ORGANISATION FOR ECONOMIC CO-OPERATION AND DEVELOPMENT

Pursuant to Article 1 of the Convention signed in Paris on 14th December 1960, and which came into force on 30th September 1961, the Organisation for Economic Co-operation and Development (OECD) shall promote policies designed:

• To achieve the highest sustainable and and a rising standard of living in member countries, while maintaining financial stability, and thus to contribute to the development of the world economy.

• To contribute to sound economic expansion in member as well as non-member countries in the process of ; and

• To contribute to the expansion of world on a multilateral, non-discriminatory basis in accordance with international obligations.

The original member countries of the OECD are Austria, Belgium, Canada, Denmark, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States. The following countries became members subsequently through accession at the dates indicated hereafter: Japan (28th April 1964), Finland (28th January 1969), Australia (7th June 1971), New Zealand (29th May 1973), Mexico (18th May 1994), the Czech Republic (21st December 1995), Hungary (7th May 1996), Poland (22nd November 1996), Korea (12th December 1996) and the Slovak Republic (14th December 2000). The Commission of the European Communities takes part in the of the OECD (Article 13 of the OECD Convention).

© OECD 2005 FOREWORD

Over the past few years, productivity and economic growth have been an important focus of OECD work. This work has included both efforts to improve the measurement of productivity growth, as shown in the development of the OECD Productivity Manual, published in 2001, as well as work to enhance the understanding of the drivers of productivity performance. In the course of this work, questions about data choices and the measurement of productivity were examined at several occasions. At the same time, OECD was confronted with a growing interest in internationally comparable statistics and indicators on productivity growth.

The continued interest of many OECD member countries in productivity led to a decision to develop an OECD Productivity Database, based on data that were considered to be as comparable and consistent across countries as possible. This database and related information on methods and sources was first made publicly available through the OECD Internet site on 15 March 2004, and is being updated and revised on a regular basis. The data is available (free of charge) at:

www..org/statistics/productivity

This compendium is the first time a large number of indicators on productivity are being combined in one document. The compendium draws heavily on the OECD Productivity Database, but also includes indicators drawn from other sources, such as the OECD STAN database, which enables productivity calculations for individual industries.

The compendium includes indicators as well as methodological notes and describes the measurement challenges and data choices that were made as well as the remaining measurement problems. Detail is available in a number of annexes.

The compendium was prepared for an OECD workshop on productivity measurement, held in Madrid from 17-19 October 2005. Agnes Cimper, Julien Dupont, Dirk Pilat, Paul Schreyer and Colin Webb prepared the text and tables in the compendium. Alessandra Colecchia, Chiara Criscuolo and Pascal Marianna contributed material. Beatrice Jeffries, Paula Venditti and Julie Branco-Marinho helped prepare the manuscript.

The data underlying this compendium is primarily based on the July 2005 update of the Productivity Database. Some minor revisions to these data were made in September, primarily affecting the estimates of productivity levels (see Annex 2) and the results for a limited number of OECD countries. A full update of the OECD Productivity Database will be released on the OECD website by the end of 2005.

Compendium of Productivity Indicators

HIGHLIGHTS

This compendium presents productivity indicators in three broad areas. The first section presents economy-wide indicators of productivity growth. It shows that:

• Growth in GDP per hour worked over 1995-2004 was highest in Ireland, Korea and the Slovak Republic. In Greece, Iceland, Ireland and the United States, labour productivity grew much faster from 1995-2004 than from 1990-95. In many other OECD countries, labour productivity slowed down over this period. Alternative measures of labour productivity growth, based on net domestic product or gross domestic income, show a very similar picture, with some exceptions.

• Capital productivity declined in most OECD countries over the past decade. The decline has been most pronounced in Japan, but also in Canada, Denmark, Portugal and Spain. Finland and Ireland are exceptions; both countries have experienced a considerable increase in capital productivity.

• Stronger growth in some OECD countries, including Canada, France and the United States, over 1995-2003 was due to a combination of factors, including increased labour utilisation, strong capital deepening in information and communications (ICT) and more rapid multi-factor productivity (MFP) growth.

• Investment in ICT accounted for between 0.35 and 0.9 percentage points of growth in GDP over the period 1995-2003. Australia, Sweden and the United States received the largest boost from ICT capital. In Ireland, Finland and Greece, MFP was an important source of GDP growth.

The second section presents indicators of productivity levels. It shows that:

• Ireland, Luxembourg, Norway and the United States had the highest levels of per capita income in 2004, while Belgium, France, Ireland, Norway and the United States had the highest levels of GDP per hour worked. The different ranking of certain countries on these two measures is due to labour utilisation; many European countries have lower levels of labour utilisation than the United States. This implies that they have fewer people contributing to GDP; levels of GDP per capita are therefore lower than levels of GDP per hour worked.

• These rankings change little when alternative measures of output, such as net domestic product or gross national income, are used. Exceptions are Ireland and Luxembourg that have a lower ranking on gross national income per hour worked than on GDP per hour worked.

• Cross-country differences in income and productivity levels have eroded considerably since the 1950s. Japan and Korea have experienced the highest rates of catch-up since 1950. Many European countries experienced strong catch-up with the United States until 1980, but have fallen back since, Norway and Ireland being among the most notable exceptions.

• Australia, New Zealand, the United Kingdom and Canada already had relatively high income levels in 1950 and have done little catching up since. Central European countries, Mexico and Turkey started with low income levels in the 1950s and have only caught up a little.

• Industries predominantly involved in the extraction, processing and supply of fuel and energy goods produced the highest per labour unit. These industries were more than twice as productive as the average industry.

• Besides the energy-producing industries, those that yield the most value added per labour unit are industries considered more technology and/or knowledge intensive. In manufacturing, the chemical industry has the highest relative labour productivity level, while in services, finance, insurance and telecommunications lead the way.

The third section presents indicators of productivity growth by industry, and also includes indicators on the contribution of multinationals to productivity performance. It shows that:

• In many OECD countries, notably in Australia, Greece, Mexico, the United Kingdom and the United States, business sector services accounted for the bulk of labour productivity growth over 1995- 2003. However, the manufacturing sector remains important in the Czech Republic, Finland, Hungary, Poland, Korea, the Slovak Republic and Sweden.

• A large share of labour productivity growth in the non-agricultural business sector is attributable to knowledge-intensive activities. ICT manufacturing and services were particularly important in Finland and Sweden, whereas other high- and medium-high-technology industries were particularly important in Japan, Sweden and the United States. In Greece, Norway and the United States, wholesale and retail trade also contributed significantly to aggregate productivity growth.

• Within manufacturing, large differences in the rate of productivity growth can be observed. Electrical and optical equipment is often the industry with the highest rate of productivity growth, up to 20% annually in OECD countries such as Sweden, Hungary, Korea and Finland.

• The variation in productivity growth across services sectors is also considerable. Industries such as wholesale and retail trade, post and telecommunications and financial intermediation are typically the services sectors with the highest rate of productivity growth.

• Labour productivity of foreign affiliates in manufacturing in the United Kingdom is more than two times higher than the average labour productivity of domestic firms in the manufacturing sector.

• Foreign affiliates made an important contribution to labour productivity growth in the United States, accounting for almost a quarter of manufacturing productivity growth over 1995-2001. In the Czech Republic, France, Sweden and the United Kingdom, the bulk of productivity growth in manufacturing was due to foreign affiliates. In Japan, foreign affiliates made only a minor contribution to productivity growth.

OECD measures of labour productivity growth The OECD Productivity Manual. There are many different approaches to the measurement of productivity. The calculation and interpretation of the different measures are not straightforward, particularly for international comparisons. To give guidance to statisticians, researchers and analysts who work with productivity measures, the OECD released the OECD Productivity Manual in 2001. It is the first comprehensive guide to various productivity measures and focuses on the industry level. It presents the theoretical foundations of productivity measurement, discusses implementation and measurement issues and is accompanied by examples from OECD member countries to enhance its usefulness and readability. It also offers a brief discussion of the interpretation and use of indicators of productivity. See: www.oecd.org/sti/measuring-ind-performance OECD Productivity Database. Productivity measures rely heavily on the integration of measures of output and input. Some of the most important differences among studies of labour productivity growth are linked to choice of data, notably the combination of employment, hours worked and GDP. To address this problem, OECD has developed a reference database on productivity at the aggregate level, with a view to resolving the problem of data consistency. In deriving estimates of labour productivity growth for the economy as a whole, the database combines information on GDP, employment and hours worked. For employment and hours worked, a special effort is made to use the best available information for each country, based on a consistent matching of data on employment and annual hours worked per person employed (see Annex 1). The database adds to the already available OECD estimates of productivity growth. In particular, the OECD Economic Outlook currently includes estimates of labour productivity growth for the business sector in its Annex Tables (see A.7). These measures respond to different purposes and should thus be considered of equal value to those published in the Productivity Database. The following differences should be noted between the two series: 1) The measures for labour and multi-factor productivity in the OECD Productivity Database refer to the total economy. They are based on a detailed assessment of labour and capital input, which incorporates adjustments for average hours worked per person employed and for capital services. These economy-wide productivity measures provide a close link to changes in GDP per capita. 2) The measures of labour productivity in the OECD Economic Outlook cover the business sector only and do not adjust for average hours worked and for capital services. The main advantage of these measures is that it excludes a large part of the economy, i.e. the public sector, in which productivity is typically poorly measured. More sophisticated measures of productivity growth in the business sector are currently under development.

By definition, the difference between the 62. two measures is most important in those countries that experienced the largest shifts in their terms of trade

Alternative measures of output

GDP is a gross measure that does not account for capital used in production. The associated loss in value, depreciation, reduces the net value of production that is available as net income in any given year. The observation has often been made that a growing part of capital goods is short-lived (for example computers), and that this structural shift in the composition of assets brings with it a higher overall depreciation. A case could thus be made to measure productivity on the basis of net output as well as GDP. Countries with a structure of fixed assets that is biased towards short-lived assets would exhibit a relatively lower NDP per hour worked than GDP per hour worked, reflecting relatively higher depreciation.

However, net measures require reliable estimates of depreciation and the empirical basis for depreciation estimates is generally not well established. For similar types of assets, significant differences exist in the service lives and depreciation rates that are used by different countries. These rates are sometimes based on assumptions more than in-depth empirical studies or are based on evidence dating back a number of years. This reduces the quality of depreciation estimates as well as their international comparability. The international GDP-NDP comparisons should thus be interpreted with caution.

It is also useful to compare GDP per hour worked with Gross Domestic Income (GDI) per hour worked over time. Real gross domestic income (GDI) measures the purchasing power of the total incomes generated by domestic production (including the impact on those incomes of changes in the terms of trade); it is equal to gross domestic product at constant prices plus the trading gain (or less the trading loss) resulting from changes in the terms of trade. The terms-of-trade effect arises because real GDI is obtained by with the price index for domestic final demand rather than the price index for GDP. It measures the rate at which exports can be traded against imports from the rest of the world. The difference between movements in GDP at constant prices and real GDI are not always small. If imports and exports are large relative to GDP, and if the commodity composition of the goods and services which make up imports and exports are very different, the scope for potential trading gains or losses may be large. If the prices of a country’s export rise faster (or fall more slowly) then the prices of its imports — that is if its terms of trade improve — less exports are needed to pay for a given volume of imports so that at a given level of domestic production of goods and services can be reallocated from exports to consumption or capital formation. Thus, an improvement in terms of trade makes it possible for an increased volume of goods and services to be purchased by residents out of the incomes generated by a given level of domestic production.

Despite its analytical usefulness, it should be borne in mind that GDI is a measure of income and not a measure of production. However, as has been pointed out by some authors (Kohli 2004), terms of trade effects resemble technical change. Changes in constant price GDP would only reflect technical change whereas GDI is a measure that reflects both technical change and terms of trade. This makes GDI a meaningful measure even in the context of production analysis.

The fewer hours worked are available of Results”, OECD Statistics Working Papers 2003/6, per unit of capital, the lower capital productivity. OECD, Paris. Generally, the cost of using capital has declined relative to labour, so that the amount of labour input per capital input has declined as well, leading to the observed fall in capital productivity.

Measuring capital input From the viewpoint of the economic theory, the objective is to measure the flow of productive services that capital delivers in production. This measure relies on the assumption that capital services are a fixed proportion of the productive capital stock. With this assumption, the rate of change of capital services coincides with the rate of change of the capital stock. The latter is estimated by cumulating investment flows and correcting them for retirement, wear and tear and obsolescence. The aggregate flow of capital services is obtained by weighting the flow of capital services of each type of asset by its share in total capital income. More information on capital measurement can be found in the documentation for the OECD Productivity Database.

International comparability of price indices Price indices are key in measuring volume investment, capital services and user costs. Accurate price indices should be constant quality deflators that reflect price changes for a given performance of ICT investment goods. Thus, observed price changes of ‘computer boxes’ have to be quality-adjusted for comparison of different vintages. There are differences how countries deal with quality adjustment with possible consequences for the international comparability of price and volume measures of ICT investment. In particular, those countries that employ hedonic methods to construct ICT deflators tend to register a larger drop in ICT prices than countries that do not. The OECD uses a set of ‘harmonised’ deflators to control for some of the differences in methodology and assumes that the ratios between ICT and non-ICT asset prices evolve in a similar manner across countries, using the United States as the benchmark. Although no claim is made that the ‘harmonised’ deflator is necessarily the correct price index for a given country, the understanding is that the possible error due to using a harmonised price index is smaller than the bias arising from comparing capital services based on national deflators. However, from an accounting perspective, adjusting the price index for investment goods for any country implies an adjustment of the volume index of output. In most cases, such an adjustment would increase the measured rate of volume output change. At the same time, effects on the economy-wide rate of GDP growth appear to be contained (see Schreyer (2001) for a discussion).

Growth accounting Economic growth can be increased in several ways; by increasing the amount and types of labour and capital used in production, and by attaining greater overall efficiency in how these are used together, i.e. higher multi-factor productivity. Growth accounting involves breaking down growth of GDP into these contributions; i.e. labour input, capital input and MFP. The growth accounting model is based on the microeconomic theory of production and rests on a number of assumptions, among which the following are important: i) production technology can be represented by a relating total GDP to the primary inputs labour L and capital services K; ii) this production function exhibits constant returns to scale; and iii) product and factor markets are characterised by perfect . For any desired level of output, the firm minimises costs of inputs, subject to the production technology discussed above. Factor input markets are competitive, so that the firm takes factor prices as given and adjusts quantities of factor inputs to minimise costs. The rate of growth of output is a weighted average of the rates of growth of the various inputs and of the multi-factor productivity term. The weights attached to each input are the output elasticities for each factor of production. Output elasticities cannot be directly observed, however, and the factor shares of labour and capital are often used as weights.

The contribution of ICT capital to GDP growth

Correct measurement of investment in ICT in both nominal and volume terms is crucial for estimating its contribution to economic growth and performance. Data availability and measurement of investment in ICT based on national accounts (SNA93) vary considerably across OECD countries, especially as regards measurement of investment in software, deflators applied, breakdown by institutional sector and temporal coverage. In the national accounts, expenditure on ICT products is considered as investment only if the products can be physically isolated (i.e. ICT embodied in equipment is considered not as investment but as intermediate consumption). This means that investment in ICT may be underestimated and the order of magnitude of the underestimation may differ depending on how intermediate consumption and investment are treated in each country’s accounts.

In particular, expenditure on software has only very recently been treated as capital expenditure in the national accounts, and methodologies still vary considerably across countries. Difficulties for measuring software investment are also linked to the ways in which software can be acquired, e.g. via rental and licences or embedded in hardware. Moreover, software is often developed on own account. To tackle the specific problems relating to software in the context of the SNA93 revision of the national accounts, a joint OECD-EU Task Force on the Measurement of Software in the National Accounts has developed recommendations concerning the capitalisation of software (Lequiller, et al., 2003; Ahmad, 2003). These are now being implemented by OECD member countries.

Measuring business sector productivity

Business sector output is defined as economy-wide GDP less the government wage bill, less net indirect taxes and government consumption of fixed capital. Business sector employment is defined as total economy employment less public sector employment. The business sector thus excludes outputs and inputs that relate to government. The main advantage of business sector measures is that they exclude a large part of the economy, i.e. the public sector, in which productivity is typically poorly measured. In the absence of production and market prices (as is the case for example for general administration), government output is normally measured by the inputs that are used to produce this output, implying zero productivity growth.

Measures of business sector productivity are also important because this sector ultimately determines the development of an economy’s potential output and of the economy's tax base. At the same time, the precise definition of the business sector is not always straightforward. Also, it can be difficult to allocate certain enterprises to the market or to the non-market sector. In their national statistics, countries use different approaches towards measuring the output and inputs of the business sector. Differences arise in particular in the treatment of health or education services that may be considered part of non-market production in some countries and part of market production in others.

Over the past few years, several countries have started to develop output-based measures of production for non-market activities. For example, the United Kingdom has put in place measures of output of education and health services in their national accounts. A report to the U.K. Office of National Statistics (Atkinson 2005) provides a comprehensive discussion of the issues involved in measuring non- market output.

Despite their conceptual advantages, business sector measures of labour productivity are subject to greater constraints of data availability than labour productivity measures for the total economy. In particular, it is difficult to obtain reliable and internationally comparable data for the total number of hours worked in the business sector, making it necessary to revert to the total number of persons employed as a measure of labour input. As long as average hours worked per person do not change significantly over time, this makes little difference to the resulting productivity measures. However, when there are marked shifts in working hours, the two measures of labour input may give rise to quite different rates of labour productivity growth.

• In many OECD countries, labour use, as measured by hours worked per capita, is substantially lower than in the United States. This is because of disparities in working hours but also in several

Comparisons of income and productivity levels Comparisons of income and productivity levels face several measurement problems (see Annex 2 for further detail). First, they require comparable data on output. In the 1993 System of National Accounts (SNA), the measurement and definition of GDP are treated systematically across countries. Most countries have implemented this system; in the OECD area, Turkey is the only exception, and its output is likely to be understated relative to other OECD countries. Other differences, such as the measurement of software investment, also affect the comparability of GDP across countries, although the differences are typically quite small. The second problem is the measurement of labour input. Some countries integrate the measurement of labour input in the national accounts; this may ensure that estimates of labour input are consistent with those of output. In most countries, however, employment data are derived from labour force surveys which are not entirely consistent with the national accounts. Labour input also requires measures of hours worked, which are typically derived either from labour force surveys or from business surveys. Several OECD countries estimate hours worked from a combination of these sources or integrate these sources in a system of labour accounts, which are comparable to the national accounts. The OECD Productivity Database includes estimates of total hours worked which aim at consistency between estimates of employment and hours worked. The cross-country comparability of hours worked remains somewhat limited, however, with a margin of uncertainty in estimates of productivity levels. Third, international comparisons require price ratios to convert output expressed in a national currency into a common unit. Exchange rates are of limited use for this purpose because they are volatile and reflect many influences, including capital movements and trade flows. The alternative is to use purchasing power parities (PPP), which measure the relative prices of the same basket of consumption goods in different countries. The estimates shown here are based on official OECD PPPs for 2004.

Alternative measures of output – level comparisons

GDP is a gross measure that does not account for capital used in production. The associated loss in value, depreciation, reduces the net value of production that is available as net income in any given year. The observation has often been made that a growing part of capital goods is short-lived (for example computers), and that this structural shift in the composition of assets leads to higher overall depreciation. A case could thus be made to measure productivity on the basis of net domestic product as well as GDP. Countries with a structure of fixed assets that is biased towards short-lived assets would exhibit a relatively lower NDP per hour worked than GDP per hour worked, reflecting relatively higher depreciation.

However, net measures require reliable estimates of depreciation and the empirical basis for depreciation estimates is generally not well established. For similar types of assets, significant differences exist in the service lives and depreciation rates that are used by different countries. These rates are sometimes based on assumptions more than in-depth empirical studies or are based on evidence dating back a number of years. This reduces the quality of depreciation estimates as well as their international comparability. The international GDP-NDP comparisons should thus be interpreted with caution.

It is also useful to compare GDP with gross national income (GNI). This comparison permits to take into account the payments received from or sent to the rest of world. GNI is equal to GDP less net taxes on production and imports, less compensation of employees and income payable to the rest of the world plus the corresponding items receiving from the rest of the world. For example, when company profits are transferred abroad, this leads to GNI being lower than GDP. Conversely, when foreign affiliates or domestic firms or residents abroad transfer payment to the domestic economy, this will raise GNI relative to GDP.

At the same time it should be noted that income-based measures, while useful from a perspective, are not necessarily the preferred indicator when it comes to measuring productivity. The purpose of productivity measures is to capture inputs and outputs in a production process and GNI may not be the best measure of output for this purpose.

Measuring labour productivity by industry

The indicators shown here are determined by data availability and simply measure value added per person employed. Further adjustments to labour input, including adjustment for part-time work and hours worked per worker, can be made for certain OECD countries but international comparisons by industry are not yet feasible. A few other notes apply to the indicators:

• For the labour productivity levels, 2002 value added at current prices was used. For the European Union, member countries' value added data were aggregated after applying 2002 US dollar GDP purchasing power parities (PPPs). Industry-specific PPPs are preferable, but are not available for all sectors and countries.

• The labour productivity levels by industry are relative to the total non-agriculture business sector. This consists of all industries except i) Agriculture, hunting, forestry and fishing (ISIC 01-05); ii) Real estate activities (ISIC 70 - for value added this includes imputed rent of owner occupied dwellings); and iii) Community, social and personal services (ISIC 75-99 - this includes mainly non-market activities such as public administration, education and health for which, in some countries, there are still some measurement problems). This activity-based definition is not to be confused with an institutional definition of the business sector (see A.7).

• Sectors that are considered technology- and/or knowledge-intensive are highlighted in the graphs. For manufacturing, R&D intensity is the main determinant broadly identifying Chemicals (ISIC 24), Machinery and equipment (ISIC 29-33) and Transport equipment (ISIC 34-45) as high or medium-high technology sectors (see Annex 1, of STI Scoreboard 2003 for more details). For services, preliminary analyses of embodied technology (based on input-output tables) and composition of workforce skills have complemented limited R&D intensity information to describe the following broad service sectors as knowledge intensive: Post and telecommunications (ISIC 64); Finance and Insurance (ISIC 65-67) and Business services (ISIC 71-74).

• The European Union in this section covers the 15 member countries up to 2004 plus two new members, the Czech Republic and Hungary.

• Data on value added for the EU countries is expressed in basic prices; for Japan and the United States, it is at factor costs.

Measuring labour productivity growth by industry

Labour productivity growth can be calculated as the difference between the rate of growth of output or value added and the rate of growth of labour input. Calculating a sector’s contribution to aggregate productivity growth requires a number of simple steps, as explained in the OECD Productivity Manual. First, the aggregate rate of change in value added is a share-weighted average of the industry-specific rate of change in value added, with weights reflecting the current price share of each industry in value added. On the input side, aggregation of industry-level labour input is achieved by weighting the growth rates in hours worked by industry with each industry’s share in total labour compensation. Aggregate labour productivity growth can then be calculated as the difference between aggregate growth in value added and aggregate growth in labour input. An industry’s contribution to aggregate labour productivity growth is therefore the difference between its contribution to total value added and total labour input. If value added and labour shares are the same, total labour productivity growth is a simple weighted average of industry-specific labour productivity growth. Similar approaches can be followed when production, instead of value added, is used as the output measure. However, OECD work on the basis of the STAN database has typically focused on value added, since constant price series of value added are more widely available across OECD countries than constant price series of production. Difficulties in measuring output and productivity in services sectors should also be taken into consideration when interpreting the results (see Wölfl, 2003).

Due to rapid technological progress, main driver of aggregate productivity growth in measuring productivity growth in this industry is OECD countries. While its contribution to aggregate particularly difficult.

Electrical and optical equipment is among the manufacturing industries with the highest rate of productivity growth, up to 20% annually in OECD countries such as Sweden, Hungary, Korea

Hedonic methods

Examining the role of ICT-producing sectors in economic growth is heavily influenced by measurement problems, both regarding outputs and inputs. The key measurement problem for the manufacturing of ICT goods on both the output and input side concerns prices, in particular how to statistically capture significant quality improvements associated with technological advances in goods such as computers and semi-conductors. The use of hedonic deflators is generally considered as the best way to address these problems. Several countries currently use hedonic methods to deflate output in the computer industry (e.g. Canada, Denmark, France, Sweden and the United States). However, these countries do not use exactly the same method. Some countries, such as the United States , apply their own hedonic deflator, others apply the US hedonic deflator adjusted for exchange rates, and yet other OECD countries apply conventional deflators.

Adjusting for these methodological differences in computer deflators for the purpose of a cross-country comparison is difficult, since there are considerable cross-country differences in industrial specialisation. Only few OECD countries produce computers, where price falls have been very rapid; many only produce peripheral equipment, such as computer terminals. Similar differences in industry composition exist in Radio, Television and Communication Equipment (ISIC 32), which includes the semi-conductor industry. The differences in the composition of output are typically larger than in computer investment, where standardised approaches have been applied (e.g. Schreyer, et al. 2003).

(2005), “The Service Economy in OECD OECD countries. Productivity growth rate in social Countries”, STI Working Paper 2005/3, OECD, Paris. services are not shown in the charts, as many OECD countries still measure the output of these services through their inputs.

Measuring productivity in services The service sector now accounts for about 70 to 80% of aggregate production and employment of OECD economies and continues to grow. But measuring output and productivity growth in many services is not straightforward. What exactly does a lawyer or produce? How can the rapidly-changing pricing schemes of telecommunications providers be compared over time? And how should one measure the ‘quantity’ of health services provided by public hospitals? These and similar questions arise when statisticians attempt to measure the production of services and the output of service industries and the difficulty of this task is hard to overstate. Generally, measuring volumes in the national accounts requires that current-price values of flows of goods and services can be divided into volume and price components. Typically, this is more difficult for services than for goods. Characteristics of goods can normally be identified and changes in quantities and qualities are measurable in principle, whereas for services even quantitative changes are often hard to measure, let alone quality change. Omitting qualitative changes does not necessarily mean that volume of services will be underestimated. For example, technical progress may improve the quality of medical services but may also lead to a decline in quality when, for example, self-service in post offices, longer queuing times or increased distances to the nearest post office all of which reflect an increased burden on customers and a lower quality of services. At the level of individual industries, two types of measurement issues arise: comparability of current-price measures, and comparability of the price indices used to deflate the latter or, in some cases, the comparability of volume indices. When it comes to the impact of service industry measures on the comparability of aggregate GDP series, two other factors come into play. The first is the extent to which a particular service industry’s output is bought as intermediate input by other domestic producers as opposed to the share of output that is delivered to final demand (private consumption, investment, government and export). The larger the share of the former, the smaller the impact of a measurement error at the industry level on measures of aggregate GDP growth, and vice versa: if a service industry delivers exclusively for final demand purposes, any possible measurement will carry over to measures of total GDP. The second factor is the size of the industry in question, or more precisely, its share in economy-wide value-added. The larger the share, the bigger the potential impact of an incorrect measure of industry-level output.

Measuring labour productivity of foreign affiliates in host countries

In the calculations shown here, the choice of measurement of labour productivity was largely determined by the availability of data. Even at the level of total manufacturing, it was not possible to calculate total factor productivity, since no data on capital stock were available for foreign affiliates. Labour productivity is measured on the basis of divided by the number of employees.

Relative labour productivity of foreign affiliates is the ratio of labour productivity of foreign affiliates compared to the national total for labour productivity in the manufacturing and services sectors.

To measure labour productivity in terms of growth for total manufacturing and services, value added data for foreign affiliates have been deflated using sectoral deflators of the national industry and re-weighing them according to the sectoral structure of foreign affiliates. These calculations have been made where possible. For some sectors, this approach was not possible due to missing data. In these cases, deflators at a higher level of aggregation were used.

Calculating foreign affiliates’ contribution to productivity growth To measure the contribution of foreign affiliates to productivity growth, the OECD has put together a database with information from the AFA, FATS and STAN databases. The database contains information on the growth of labour productivity, measured as deflated value added over employment of affiliates and non-affiliates for the manufacturing sector of 12 OECD countries and for the services sector of 9 OECD countries. Total annualised labour productivity growth is defined as the weighted sum of domestic firms’ productivity growth and foreign affiliates’ productivity growth, where the weights used are the shares of domestic and foreign affiliates in total employment, as shown in the formula below: EMP EMP it − it−k LPi t LPi t−k 1 ∆LP EMP EMP− 1 ∗ t = ∑ t t k * k LPt−k i=DOM ,FOR LPt−k k

Where LP is labour productivity calculated as the ratio of real value added to labour input (EMP), ∆ indicates change; k indicates the number of years between observations, so that the left-hand side is aggregate annualised labour productivity growth. For each sector therefore the contribution to labour productivity growth of foreign affiliates can be calculated as: ∆  EMP EMP −   1 LP 1 LP 1 k ∗  FOR,t * LP − FOR,t k * LP  LP  = * FOR,t * w + ∆w * * FOR  FOR,t FOR,t −k  t −k  FOR FOR,t  EMPt EMPt −k  k LPt −k k LPt −k   14244 4344 14244 4344 within between Foreign affiliates’ contribution to productivity growth derives from switches in labour resources between domestic and more productive foreign affiliates, the “between effect”, and from labour productivity growth within the group of foreign affiliates, the “within effect”. The first term of the right-hand side is the “within” effect and the second is the “between” effect. Thus, foreign affiliates’ contribution to labour productivity growth might increase if there is an increase in its rate of productivity growth or if their average employment share is higher (from the first term); and if their employment share increases or their labour productivity level is higher relative to the domestic average (from the second term).

ANNEX 1: OECD PRODUCTIVITY DATABASE

Over several years, the analysis of productivity and economic growth has been an important focus of OECD work. To carry out this work, OECD needs comparable data on productivity growth and its underlying drivers. There has also been significant interest in productivity data by researchers and analysts outside the OECD and this led to the development of the OECD Productivity Database, designed to be as comparable and consistent across countries as is currently possible. The database and related information on methods and sources were made publicly available through the OECD Internet site on 15 March 2004.

Coverage

The OECD Productivity Database currently provides annual estimates of

• Labour productivity growth, measured as GDP per hour worked, for 29 OECD countries and the period 1970-2004;

• Capital services and multi-factor productivity for 19 OECD countries for the period 1985-2003;

• Labour productivity levels for 2004.

All of the above data relate to the economy as a whole. In addition, the Productivity Database features industry-level measures of labour productivity growth, drawn from the OECD STAN Database, see www.oecd.org/sti/stan

The OECD Productivity Database is updated on a regular basis as new data become available. It is accessible through the OECD Internet site, at: www.oecd.org/statistics/productivity

Sources of data underlying the OECD Productivity Database

The OECD productivity database combines – to the extent possible – a consistent set of data on GDP, labour input measured as total hours worked, and capital services. The following sources are used in the productivity database.

Gross Domestic Product

Estimates for GDP are derived from OECD's Annual National Accounts (ANA). The data from ANA are based on OECD’s annual national accounts questionnaire to OECD member countries. The data resulting from this questionnaire differ somewhat from national sources and are more comparable across countries than those derived from OECD’s quarterly national accounts, thanks to several small methodological adjustments that are made. However, the differences with other OECD sources, such as the Quarterly National Accounts and the Economic Outlook database, are minor for most countries.

Employment

Equally important for international comparisons of productivity growth are comparable measures of labour input. In most comparisons of labour productivity growth, labour input is measured along only

two dimensions: the number of persons employed and the total number of hours worked of all persons employed.1

Basic data for employment can be derived from several sources, including administrative records, labour force surveys and establishment or enterprise-based surveys. Labour force surveys are typically conducted to provide reliable information about personal characteristics of the labour force, such as educational attainment, age, or the occurrence of multiple job holding, as well as information about the jobs (e.g. hours at work, industry, occupation and type of contract). Compared with most other statistical sources on employment, labour force surveys are quite well standardised across OECD countries as most countries collect their numbers on the basis of agreed guidelines, and therefore they pose few problems for international comparisons. In addition, labour force surveys have fairly comprehensive coverage of the economy. However, they are based on a national concept, which implies that they exclude non-resident workers (commuters) that are quite important for some OECD countries. Moreover, they may have lower and upper age thresholds and may exclude institutional households. Despite these shortcomings, labour force surveys are often an important source of information for comparisons of productivity growth for the aggregate economy.

The main difficulty with employment estimates from labour force surveys is that the data are not necessarily consistent in coverage with other data needed, notably GDP and hours worked. Labour force surveys are mostly defined within geographic boundaries, whereas, for example, national accounts are defined within economic boundaries. This implies, for example, that a country’s military bases and diplomatic premises on foreign soil are part of its economic territory, and that the residence of an enterprise is determined according to its “centre of economic interest”.

A second major source of employment data is therefore the national accounts. Following the introduction of SNA 1993/ESA 1995 many countries now provide data on employment in the framework of the national accounts. In principle, national accounts information on employment is preferable over labour force surveys, due to the conceptual issues discussed above and since the national accounts are likely to integrate a wider range of basic source data on employment.

In practice, the concepts and actual compilation of the national accounts estimates of employment are not yet as well standardised as labour force surveys. One issue is conceptual; most European countries provide data on persons employed in their national accounts, as is also the case with the labour force surveys. In several other OECD countries, including Austria, Canada, Greece, Japan, the United Kingdom and the United States, the national accounts data on employment refers to the number of jobs, which is closer to the concept used in establishment or enterprise statistics. This conceptual difference can be important for the resulting estimate of employment, notably in countries with a high rate of multiple job-holding, such as the United States.

Previous OECD estimates of productivity growth have sometimes used labour force surveys as a source of employment data for productivity estimates at the aggregate level. Recently, and in close co- ordination with Eurostat, OECD decided to move to the national accounts as the preferred source of employment data. This methodological change was driven by three motivations:

1. Consistency between GDP and employment. Employment estimates from the national accounts are likely to be more consistent with GDP estimates than employment estimates from labour force surveys, since the employment estimates may incorporate information from other sources of employment. For example, in several countries, e.g. Italy, GDP includes an adjustment for the informal economy. This adjustment is also reflected in the employment estimate in the national accounts. The employment number in the labour force survey is substantially lower; using this number for comparisons of productivity growth might lead to a bias in Italian estimates of labour productivity growth.

1 . A possible third dimension concerns labour composition. This dimension is currently being investigated (see Colecchia, 2005).

© OECD 2005 47

2. Conceptual. The national accounts are more appropriate from a conceptual point of view, since they use economic boundaries instead of national boundaries.

Despite this choice for the source of employment data for OECD estimates of productivity growth, it is important to be cognisant of the statistical problems that are still associated with national accounts information on employment. The first important limitation is that only 19 OECD countries currently include data on total hours worked in the framework of national accounts. These are: Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Korea, Netherlands, Norway, the Slovak Republic, Spain, Sweden, Switzerland and the United States. For most of these countries, the OECD has now moved to estimates of total hours worked from the national accounts. For the United States, the OECD does not use the BEA estimates of total hours worked, but those of the BLS, as these are the official US estimates of total labour input. For the remaining countries, the OECD continues to use data on hours worked that are collected for the OECD Employment Outlook from a variety of sources, including labour force surveys, and combines these with employment figures from national accounts to derive an estimate of total hours worked (see also Annex 2).

An additional problem is that little is known about how countries currently integrate different sources of employment information in the national accounts. It is not clear whether this is done in a similar way across countries. Moreover, some countries supply data on persons employed, others on jobs or full-time equivalents. Work is currently underway in several organisations, including the OECD and Eurostat, to examine and improve the measures of employment (and hours worked) that are included in the national accounts. This work will hopefully reduce some of the uncertainties that are associated with employment estimates in the national accounts, and the adjustments that countries make in integrating different sources of employment information.

Hours worked

Estimates of levels of GDP per hour worked require estimates of total hours worked that are consistent across countries and consistent with GDP. For most of the 19 countries for which total hours worked are available in the national accounts (with the exception of the United States), these data are used in the productivity calculations. For the other countries, consistency is currently achieved by matching the hours worked per person that are collected by the OECD for its annual OECD Employment Outlook with the national accounts measure of employment for each individual country. Estimates of average hours actually worked per year per person in employment are currently available on an annual basis for 27 OECD countries from the OECD Employment Outlook, whereas estimates of average hours per person in dependent employment are available for two additional countries (see OECD (2004), Statistical Annex Table F). These estimates are available from National Statistical Offices for 20 countries. Employment Outlook estimates for several countries (including Australia, Canada, France, Norway, Sweden and Switzerland) are fully consistent with National Accounts concepts and coverage and are thus typically the same as those derived from the OECD Annual National Accounts Database.

To develop their estimates of average hours worked, countries use the best available data sources for different categories of workers, industries and components of variation from usual or normal working time (e.g. public holidays, annual leave, , absences from work due to illness and to maternity, etc.). For example, in 2 countries (Japan and United States) actual hours are derived from establishment surveys for regular or production/non-supervisory workers in employee jobs and from labour force surveys (LFS) for non-regular or managers/non-supervisory employees, self- employed, farm workers and employees in the public sector. In 3 other countries (France, Germany and Switzerland), the measurement of annual working time relies on a component method based on standard working hours minus hours not worked due to absences plus hours worked overtime. Standard working hours are derived from an establishment survey (hours offered), an administrative source (contractual hours) and the labour force survey (normal hours), respectively. The coverage of workers is extended using standard hours reported in labour force surveys or other sources as hours

worked overtime. Vacation time is either derived from establishment-survey data on paid leave or the number of days of statutory leave entitlements. Hours lost due to sickness are estimated from the number of days not worked from social security registers and/or health surveys.

On the other hand, the national estimates for 12 more countries (i.e. Australia, Canada, Czech Republic, Finland, Iceland, Mexico, New Zealand, Poland, Slovak Republic, Spain, Sweden and United Kingdom) rely mainly on labour force survey results. Annual working hours are derived using a direct method annualising actual weekly hours worked, which cover all weeks of the year in the case of continuous surveys. But, for labour force surveys with fixed monthly reference weeks, this method results in averaging hours worked during 12 weeks in the year and, therefore, necessitates adjustments for special events, such as public holidays falling outside the reference week (i.e. Canada and Finland). Finally, estimates of annual working time for 7 other EU member states (Austria, Belgium, Greece, Ireland, Italy, the Netherlands and Portugal) are derived by the OECD Secretariat for the OECD Employment Outlook by applying a variant of the component method to the results of the Spring European Labour Force Survey (ELFS).

Two other considerations should be kept in mind. First, annual working-time measures are reported either on a job or on a worker basis. To harmonise the presentation, annual hours worked measures can be converted between the two measurement units by using the share of multiple job holders in total employment, which is available in labour force surveys, albeit no further distinction is possible between second and more jobs.2 This difference is particularly important in matching annual working time estimates to employment estimates. Some countries provide employment estimates in the national accounts on the basis of jobs; for these countries, it is important to ensure that the measure of annual working-time per person that is used reflects jobs instead of workers. In Canada and Japan, the estimates of average hours worked already refer to hours per job. For the United Kingdom, the national accounts estimates of employment also refer to jobs, but preference has been given to employment estimates from the ONS labour force survey, since these are consistent with official UK productivity estimates.

Second, given the variety of data sources, of hours worked concepts retained in data sources, and of measurement methodologies (direct measures or component methods3) to produce estimates of annual working time, the quality and comparability of annual hours worked estimates are constantly questioned, and are subject to at least two probing issues:

• Labour force survey-based estimates are suspected of over-reporting hours worked compared to work hours reported in time-use surveys, in particular for those working long hours, like managers and professionals.

• Employer survey-based estimates do not account for unpaid overtime hours and are sometimes suspected of under-reporting hours worked, with consequences on productivity levels and growth.

The comparability of measures of hours worked across OECD countries thus remains an issue, and work is currently underway, notably through the Paris Group, the UN city group on Labour and Compensation, to further improve the available measures of hours worked. Data on hours worked are best suited for comparisons of trends over time, although comparisons of the level of average annual hours of work for a given year can be informative if the cross-country differences are sufficiently large.

2. For example, the BLS-Office of Productivity and Technology (OPT) estimates of annual hours of work for the United States are reported on a (per) job basis and are later converted by the OECD Secretariat to a per worker basis by multiplying the job-based annual hours of work by (1 + CPS based share of multiple jobholders in total employment). 3 . However, both methods can be summarised by the following identity: Annual hours per worker = Standard weekly hours worked x Number of weeks actually worked over the year = Weekly hours actually worked x 52 weeks, considering weekly reference period for reporting hours worked.

These data are incorporated, to the extent available, in the OECD estimates of productivity levels for 2004 presented in this compendium. Source: OECD (2005).

Capital input

The appropriate measure for capital input within the growth accounting framework is the flow of productive services that can be drawn from the cumulative stock of past investments in capital assets (see OECD, 2001a). These services are approximated by the rate of change of the ‘productive capital stock’ – a measure that takes account of wear and tear, retirements and other sources of reduction of the productive capacity of fixed assets. Flows of productive services of an office building, for instance, are the protection against rain or the comfort and storage services that the building provides to personnel during a given period (Schreyer et al., 2003). The price of capital services per asset is measured as their rental price. If there are markets for capital services, as is the case for office buildings, for instance, rental prices could be directly observed. For most assets, however, rental prices have to be imputed. The implicit rent that capital good owners ‘pay’ themselves gives rise to the terminology ‘user costs of capital’.

Compendium of Productivity Indicators

Capital input (S) is measured as the volume of capital services, assumed to be in a fixed proportion to the productive capital stock (see Schreyer, et al., 2003 for a more extensive explanation and for details of the computation of capital services). The productivity database publishes capital services data with calculations based on the perpetual inventory method (PIM) The PIM calculations are carried out by OECD, using service lives for different assets that are common across countries and correcting for differences in deflators for information and communication technology assets. Sources for the investment series by type of asset underlying the capital services series are national statistical offices4 and the Groningen Growth and Development Centre Total Economy Growth Accounting Database5 (http://www.ggdc.net).

Measures of multi-factor productivity in the OECD Productivity Database

The following methodology has been applied for the computation of multi-factor productivity (MFP) measures:

Rates of change of output

Output (Q) is measured as GDP at constant prices for the entire economy. Year-to-year changes Q are computed as logarithmic differences: ln( t ) Q t−1

Rates of change of labour input

Labour input (L) is measured as total hours actually worked in the entire economy. Data on total hours has been specifically developed for the present purpose, see above. Year-to-year changes are L computed as logarithmic differences: ln( t ) . Lt−1

Rates of change of capital input

i = Capital services are computed for six different types of assets (St i 1,2,...7 ) and aggregated to an overall rate of change of capital services by means of a Törnqvist index:

i i i  St  7 1 i i  St  i u tSt ln  = ()v + v − ln  with v ≡   ∑i=1 2 t t 1  i  t 7 i i St−1 St−1 u S     ∑i=1 t t

7 where vi is the share of each asset in the total value of capital services uiSi . In this t ∑i=1 t t i i i expression, the value of capital services for each asset is measured by u tSt where u t is the user i cost price per unit of capital services and St is the quantity of capital services in year t.

Cost shares of inputs

The total cost of inputs is the sum of the remuneration for labour input and the remuneration for capital services. Remuneration for labour input has been computed as the average remuneration per employee multiplied by the total number of persons employed. This adjustment was necessary to

correct for self-employed persons whose income is not part of the compensation of employees as registered in the national accounts. The source for data on compensation of employees and for the number of employees as well as the number of self employed is the OECD Annual National Accounts.

 COMP  =  t  w t L t  E t  EE t 

where

w t Lt : remuneration for labour input in period t

COMPt : compensation of employees in period t

EE t : number of employees in period t

E t : total number employed (employees plus self-employed) in period t.

Total cost of inputs is then given by:

7 C = w L + uiSi and the corresponding cost shares are t t t ∑i=1 t t

L ≡ w t Lt st for labour input and Ct

6 uiSi S ≡ ∑i=1 t t st for capital input. Ct

Total inputs

The rate of change of total inputs is a weighted average of the rate of change of labour and capital input with the respective cost shares as weights. Aggregation is by way of a Törnqvist index number formula:

Compendium of Productivity Indicators

Why does the OECD publish different productivity measures?

The release of the OECD Productivity Database adds several new measures to the already available OECD estimates of productivity growth. In particular, the OECD Economic Outlook currently includes estimates of labour productivity growth for the business sector in its Annex Tables (see A.7). These measures respond to different purposes and should thus be considered of equal value to those published in the Productivity Database. The following differences should be noted between the two series:

1. The measures for labour and multi-factor productivity in the OECD Productivity Database refer to the total economy. They are based on a detailed assessment of labour and capital input, which incorporates adjustments for average hours worked per person employed and for capital services. These economy-wide productivity measures provide a close link to changes in GDP per capita.

2. The measures of labour productivity in the OECD Economic Outlook cover the business sector only and do not adjust for average hours worked and for capital services. The main advantage of these measures is that it excludes a large part of the economy, i.e. the public sector, in which productivity is typically poorly measured. Measures of business sector productivity are also important because this sector ultimately determines the development of potential output and the economy’s tax base.

In the medium term, OECD intends to develop more sophisticated measures of productivity for the business sector, incorporating adjustments for hours worked and capital services. Data constraints currently do not permit this for most OECD countries, primarily due to lack of data on capital services for the business sector.

ANNEX 2: OECD ESTIMATES OF LABOUR PRODUCTIVITY LEVELS

Introduction

International comparisons of productivity growth can give useful insights in the growth process, but should ideally be complemented with international comparisons of income and productivity levels. An examination of income and productivity levels may give insights into the possible scope for further gains, and also places a country’s growth experience in the perspective of its current level of income and productivity. OECD has published estimates of labour productivity levels in various studies (e.g. Scarpetta, et al., 2000; OECD, 2003), and has recently released estimates of productivity on the OECD Internet site, at: www.oecd.org/statistics/productivity

Since the release of OECD estimates of productivity growth in the OECD Productivity Database in March 2004 (see Annex 1), more attention has turned to the measurement of productivity levels, since these serve as a yardstick of economic performance in many OECD countries. Several statistical agencies and international organisations, including Eurostat, the UK Office of National Statistics, the US Bureau of Labor Statistics, and the International Labour Organisation, now release estimates of labour productivity levels, as do some academic institutions, such as the Groningen Growth and Development Centre, and some private institutions, such as the Conference Board. In several instances, notably in the case of Eurostat and the ONS, estimates of labour productivity levels serve as official yardsticks of economic performance and are used to measure progress with regards to explicit policy targets.

Given the importance attached to labour productivity levels, it is unfortunate that there is still considerable variation in the currently available estimates. Primarily, this seems due to differences in the choice of basic data. Indeed, much of the differences can be brought back to how different organisations select and combine information on the three components of labour productivity levels at the economy-wide level. These components are gross domestic product, labour input and a conversion factor for total GDP (typically a purchasing power parity or PPP) that is needed to translate output in national currency units to a common currency.

This annex briefly discusses some of the main measurement issues for these components, as well as the different data choices that can be made. It focuses on the current OECD approach to measuring labour productivity levels, but also refers to other possible approaches, where appropriate. The discussion focuses on comparisons of labour productivity at the economy-wide level; the estimation of productivity levels for individual industries raises additional measurement issues that go beyond the scope of this annex.6

Output: comparability and data choices

Most comparisons of labour productivity levels focus on GDP as the measure of output. Other measures of aggregate output, such as GNP or national income, have also been used in a few studies, but are not considered here. The measurement and definition of economic output is treated systematically across countries in the 1993 System of National Accounts (SNA 93). Most countries in the OECD area have now implemented the 1993 SNA, Turkey being the only exception, which implies that its level of GDP is likely to be somewhat understated relative to other OECD countries. Despite the harmonisation of GDP estimates through the 1993 SNA, there are some differences in estimation methods across countries, however (Ahmad, et al., 2003). These typically have only a small effect on growth rates, but may be substantially more important for comparisons of output and productivity

6 . A forthcoming OECD reader discusses these issues in greater detail (OECD, forthcoming).

Compendium of Productivity Indicators

levels. Some of the main differences that are known to affect GDP levels are the following (Ahmad, et al., 2003):

• Expenditure on military equipment. The coverage of government investment in the US National Income and Product Accounts (NIPA) is more extensive than that recommended by the SNA, since it includes expenditures on military equipment (aircraft, ships, missiles) that are not considered assets by the SNA. The national accounts in most other OECD countries strictly follow the SNA in this matter. As the amount of public investment affects GDP, this results in a statistical difference in the measurement of GDP. Convergence on this issue is expected in the next edition of the SNA, in 2008. In the meantime, the OECD publishes data in its Annual National Accounts Database for the United States which adjust for this difference.

• Financial Intermediation Services. Most banking services are not explicitly charged. Thus, in the SNA, the implicit production of banks is estimated using the difference between interests received and paid. All OECD member countries have estimated this part of bank production, known as “Financial Intermediation Service Indirectly Measured” or “FISIM”. While it is relatively straightforward to recognise and estimate FISIM, the key problem is breaking it down between final consumers (households) and intermediate consumers (business and government). Only the first part has an overall impact on GDP. In the United States, Canada and Australia, such a breakdown has been estimated in the national accounts for some time, in accordance with the SNA. In Europe and Japan, the implementation of a breakdown between final and intermediate consumers has been delayed. The recent comprehensive revision of the US accounts has significantly reduced the difference in GDP levels linked to this factor to just over 1% of GDP, roughly halving the impact on growth. The EU member states and Japan are currently in the process of implementing the allocation of FISIM in their accounts. This methodological difference should be mostly eliminated in 2005, but will still affect comparisons of GDP and productivity levels as long as countries have not all implemented the new method.

• Software investment. Another significant issue in the comparability of GDP concerns the measurement of software. The 1993 SNA recommended that software expenditures be treated as investment as long as the acquisition satisfied conventional asset requirements. This change added nearly 2% to GDP for the United States, around 0.7% for Italy and France, and about 0.5% for the United Kingdom. Doubts on the comparability of these data were raised when comparing “investment ratios”, which are defined as the share of software expenditures that are recorded as investment to total expenditures in software. These ratios range from under 4% in the United Kingdom to over 70% in Spain (Lequiller, et al., 2003; Ahmad, 2003). A priori, one would expect that these are roughly the same across OECD countries. An OECD-Eurostat Task Force confirmed that differences in estimation procedures contributed significantly to the differences in software capitalisation rates, and a set of recommendations describing a harmonised method for estimating software were formulated (Lequiller, et al, 2003; Ahmad, 2003). Most of these recommendations will be implemented by countries, but this will only happen gradually. Differences in software measurement will therefore continue to have an impact on the comparability of GDP levels for some time to come.

• The informal economy. Another factor that may influence the comparability of GDP across countries is size of the non-observed economy. In principle, GDP estimates in the national accounts take account of this part of the economy. In practice, questions can be raised about the extent to which official estimates have full coverage of economic activities that are included in GDP according to the SNA, or to which extent there some under-reporting is involved. Large differences in coverage could substantially affect comparisons of productivity levels.

It is not clear, a priori, how large the impact of these, and possible other, differences is on GDP levels. What is clear, however, is that there is a margin of uncertainty associated with the comparability of levels of GDP across countries. Consequently, there is also a range of uncertainty associated with estimates of productivity levels; small differences between countries (of a few percentage points) will obviously fall within this range of uncertainty. This is important in interpreting estimates of productivity levels; countries within a small range of income and productivity levels may not have income and productivity differences that are statistically or economically significant (Schreyer and Koechlin, 2002).

The data choices for GDP are fairly uniform across different sources. In the OECD estimates of productivity levels, data on GDP are derived from OECD's Annual National Accounts (ANA). The data from ANA are based on OECD’s annual national accounts questionnaire to OECD member countries. The data resulting from this questionnaire may differ somewhat from national sources and are more comparable across countries than those derived from OECD’s quarterly national accounts (or the OECD Economic Outlook database), thanks to some small methodological adjustments that are made. For example, the US GDP estimates are adjusted for expenditure on military equipment, as discussed above. However, the differences with other OECD sources, such as the Quarterly National Accounts and the Economic Outlook database, are minor for most countries.

For two countries, Australia and New Zealand, the OECD’s Annual National Accounts provides GDP estimates for fiscal years. This creates an inconsistency with other countries, since comparisons of productivity levels ideally should correspond to the same (calendar) year. However, this problem is considered relatively limited and no adjustment is made.

Labour input

Of great importance for international comparisons of productivity levels are comparable measures of labour input. The OECD estimates of labour productivity levels are typically based on the same data choices as the OECD estimates of labour productivity growth.7 Annex 1 therefore provides a more detailed discussion of the measures of labour input used in the calculations of productivity levels.

Purchasing power parities for international comparisons

The comparison of income and productivity across countries also requires purchasing power parity (PPP) data for GDP. Exchange rates are not suitable for the conversion of GDP to a common currency, since they do not reflect international price differences, and since they are heavily influenced by short-term fluctuations. The estimates used by the OECD are derived from its joint programme with Eurostat and refer to current-price PPPs (Schreyer and Koechlin, 2002). For the current set of comparisons, the most recent PPP benchmark comparison (for 2002) is used as the basis for the estimates.

The OECD does not recommend the use of PPP-adjusted estimates of GDP in time series, because of the difficulty to obtain PPPs that are consistent over time. This is why only one year of productivity level comparisons is included in the OECD Productivity Database. Users interested in adding a time dimension to this one year level comparison should use the corresponding database on productivity growth, which gives appropriate indices of productivity growth for individual OECD countries over a long time period.

7. Some OECD countries have only very recently included estimates of hours worked in the national accounts. To the extent possible, these estimates have been incorporated in the OECD estimates of productivity levels, as presented in Annex Table 2. They have not yet been fully incorporated in the OECD estimates of productivity growth and in the data choices for those calculations, as shown in Annex Table 1. This difference will be addressed in the next update of the OECD Productivity Database, which is planned for end-2005.

OECD estimates of labour productivity levels for 2004, September 2005

Clearly, data for international comparisons of income and productivity are not perfect and some choices between different sources have to be made. In the OECD approach, GDP is derived from the OECD ANA database, which incorporates the latest comparative information on GDP from OECD member countries. Data on employment for most countries are also from the OECD national accounts as these should have a better correspondence to the estimates of GDP. For a limited number of countries, no appropriate employment estimates are currently available from the national accounts, in which case employment is derived from the OECD Labour Force Statistics. Estimates of hours worked are either from the national accounts, or from the OECD Employment Outlook, as discussed in Annex 1. To convert GDP to a common currency, the OECD uses current PPPs, which are developed in the OECD-Eurostat PPP programme.

Annex Table 2 presents the data choices and the resulting productivity level estimates for 2004. These estimates still require further work in the following ways:

1. The estimates of annual hours worked per person for several OECD countries are not yet consistent with the national accounts. Data on hours worked currently reach the OECD through two data collections. First, 29 OECD countries currently provide data on hours worked to the annual data collection for the OECD Employment Outlook; 7 of these countries provide the OECD with estimates of annual hours worked that are consistent with national accounts concepts and coverage. Secondly, 19 countries currently provide estimates of total hours worked in the framework of the national accounts for inclusion in OECD’s Annual National Accounts. Further investigation of these estimates of hours worked is needed.

2. The employment estimates that are currently incorporated in the national accounts are not necessarily consistent across countries or with the corresponding estimate of GDP. Addressing this problem will require further statistical work.

For analytical purposes, it is important that estimates of GDP per hour worked are combined with estimates of GDP per capita and estimates of GDP per person in the labour force and GDP per person of working age. The national accounts currently often do not include the necessary information on working-age population and labour force, and such data have commonly been derived from labour force statistics. The OECD’s change in method towards the national accounts as the main source of employment information requires that the link between labour force statistics (i.e. national concepts) and national accounts estimates of productivity (i.e. domestic concepts) is addressed.

ANNEX 3: OECD DATABASES RELEVANT TO PRODUCTIVITY ANALYSIS

Annual National Accounts (ANA): The OECD’s Annual National Accounts presents a consistent set of data mainly compiled on the basis of the 1993 System of National Accounts (SNA). It contains data from 1970 whenever possible for OECD member countries. The database contains a wide selection of accounts: main aggregates (GDP by expenditure, GDP by kind of activity, GDP by income and disposable income, saving and net lending), detailed breakdown by kind of activity for gross value added (at current and constant prices), components of value added, gross fixed capital formation, employment and hours worked. It also includes final consumption expenditure of households by purpose and simplified accounts for general government. Detailed accounts by institutional sector are also available. The database also provides comparative tables based on exchange rates and purchasing power parities.

Publications: OECD, National Accounts of OECD Countries, Volume I, 1992-2003, Main Aggregates, 2005 Edition; OECD, National Accounts of OECD Countries: Detailed Tables 1992/2003, Volume II, 2005 Edition. Also available annually on line on SourceOECD (www.sourceoecd.org).

Labour Force Statistics (LFS): The OECD’s Labour Force Statistics provides detailed statistics on population, labour force, employment and unemployment, broken down by gender, as well as unemployment duration, employment status, employment by sector of activity and part-time employment. It also contains participation and unemployment rates by gender and detailed age groups, as well as comparative tables for the main components of the labour force. Data are available for each OECD member country and for OECD-Total, Euro zone and EU15. The time series cover 20 years for most countries. It also provides information on the sources and definitions used by Member countries in the compilation of statistics.

Publication: OECD, Labour Force Statistics: 1984-2004, 2005 Edition. Also available annually on line on SourceOECD (www.sourceoecd.org).

Economic Outlook (EO): The OECD Economic Outlook Database is a comprehensive and consistent macroeconomic database of the OECD economies, covering expenditures, foreign trade, output, employment and unemployment, interest rates and exchange rates, the balance of payments, outlays and revenues of government and of households, and government debt. For the non-OECD regions, foreign trade and current account series are available. The database contains yearly and quarterly information, both for the historical period and for the projection period. The historical data is based on data from national statistical agencies and OECD sources such as the Quarterly National Accounts, the Annual National Accounts, the Quarterly Labour Force Statistics, the Annual Labour Force Statistics and the Main Economic Indicators.

Publication: OECD, Economic Outlook, twice yearly. The database is available on CD-ROM: http://www.oecd.org/dataoecd/47/40/32108765.pdf A statistical annex to the OECD Economic Outlook is available at: http://www.oecd.org/document/61/0,2340,en_2649_34109_2483901_1_1_1_1,00.html

Productivity Database: The OECD Productivity Database is a database on productivity at the aggregate level that is designed to be as comparable and consistent across countries as is currently possible (see Annex 1). The database and related information on methods and sources were made publicly available through the OECD Internet site on 15 March 2004. The OECD Productivity Database currently provides annual estimates of:

• Labour productivity growth, measured as GDP per hour worked, for 29 OECD countries and the period 1970-2004 (PROD);

© OECD 2005 59

• Capital services and multi-factor productivity for 19 OECD countries for the period 1985-2003 (CAP);

• Labour productivity levels for 2004 (see Annex 2; PRODL).

The OECD Productivity Database is updated on a regular basis as new data become available. It is accessible through the OECD Internet site, at: www.oecd.org/statistics/productivity

STAN: The STAN database for Industrial Analysis includes annual measures of output, labour input, investment and international trade by economic activity which allow users to construct a wide range of indicators focused on areas such as productivity growth, competitiveness and general structural change. The industry list based on the International Standard Industrial Classification (ISIC) Rev. 3, provides sufficient details to enable users to highlight high-technology sectors and is compatible with those lists used in related OECD databases in the ‘STAN’ family (see below). STAN- Industry is primarily based on member countries’ annual National Accounts by activity tables and uses data from other sources, such as national industrial surveys/censuses, to estimate any missing detail. Since many of the data points in STAN are estimated, they do not represent the official member country submissions. See: www.oecd.org/sti/stan

Publication: STAN-industry is available on line via SourceOECD ( www.sourceoecd.org) where it is regularly updated (new tables are posted as soon as they are ready). A “snapshot” of STAN- industry is also available on CDROM together with the latest versions of STAN – R&D (ANBERD), STAN – Bilateral Trade and a set of derived STAN Indicators. See www.oecd.org/sti/stan/indicators.

AFA: The Activities of Foreign Affiliates database presents detailed data on the performance of foreign affiliates in the manufacturing industry of OECD countries (inward and outward investment). The data indicate the increasing importance of foreign affiliates in the economies of host countries, particularly in production, employment, value added, research and development, exports, wages and salaries. AFA contains 18 variables broken down by country of origin and by industrial sector (based on ISIC Rev. 3) for 23 OECD countries.

Publication: OECD, Measuring Globalisation: Economic Globalisation Indicators, 2005 Edition. Also available annually on line on SourceOECD (www.sourceoecd.org).

FATS: This database gives detailed data on the activities of foreign affiliates in the services sector of OECD countries (inward and outward investment). The data indicate the increasing importance of foreign affiliates in the economies of host countries and of affiliates of national firms implanted abroad. FATS contains five variables (production, employment, value added, imports and exports) broken down by country of origin (inward investments) or implantation (outward investments) and by industrial sector (based on ISIC Rev. 3) for 21 OECD countries.

Publication: OECD, Measuring Globalisation: Economic Globalisation Indicators, 2005 Edition. Also available annually on line on SourceOECD (www.sourceoecd.org).
