« STATISTICS STATISTICS 2002 Measuring the Non-Observed Economy A Handbook Good-quality national accounts are vital for economic policy making and research. An important aspect of their quality is the extent to which they cover all economic activities. However, exhaustive coverage is difficult to achieve. Activities may have been excluded from the statistics used to compile the national accounts because they are underground, illegal, informal, household production for own final use, or due to deficiencies in the basic data Measuring the collection system. Such activities are said to comprise the non-observed economy, and including them in the national accounts is referred to as measurement of the non-observed economy. The aim of the Handbook is to identify and promote best practice for measurement of the non-observed economy Non-Observed that is consistent with international standards and, in particular, with the 1993 System of National Accounts. In addition, the Handbook indicates how stand-alone estimates of the informal sector, of underground production, of household production for own final use, and of some illegal activities, may be obtained. Economy The Handbook is aimed at producers and users of macroeconomic statistics. The primary audience is the staff of statistical offices involved in the collection of macroeconomic statistics and preparation of the national accounts. In addition, the Handbook may prove useful to those who have reason to be concerned about overall levels of economic production and what may be missing. It may also benefit researchers and journalists who are confronted with a plethora of alternative measures of the underground, hidden, shadow economy, etc., and who would like to Measuring the Non-Observed Economy: A Handbook know why these measures are all different and which can be regarded as the most reliable.

FOREWORD AND ACKNOWLEDGEMENTS Complete coverage of economic production is a vital aspect of the quality of the national accounts. This exhaustiveness is hard to achieve because of the difficulties in accounting for certain types of productive activities. Activities that are missing from the basic data used to compile the national accounts because they are underground, illegal, informal, household production for own final use, or due to deficiencies in the basic data collection system are referred to as non-observed. They are said to comprise the non-observed economy (NOE), and including them in the national accounts is referred to as measurement of the NOE. Given the wide range of possible approaches to NOE measurement, there is a need to identify and promote international best practice. This is the aim of the Handbook. It presents a systematic strategy for achieving exhaustive estimates of gross domestic product that is consistent with international standards and, in particular, with the 1993 System of National Accounts. The Handbook was put together by a team drawn from national and international statistical organisations. The principal contributors were Adriaan Bloem, Manlio Calzaroni, Jacques Charmes, Michael Colledge (editor), Ralf Hussmanns, Youri Ivanov, Brugt Kazemier, Andrei Kosarev, Ronald Luttikhuizen, Sabina Ronconi, Manik Shrestha, Seppo Varjonen, Peter van de Ven and Denis Ward. Derek Blades provided detailed comments on all chapters. Helpful advice and comments were also received from Misha Belkindas, Peter Harper, Anne Harrison, Ralf Hein, Victor Holovko, Olga Ivanova, Irina Masakova, Paul McCarthy, Brian Newson, Vitezslav Ondrus, Gerhard Reinecke, Silke Stapel, Alexander Surinov and Jiri Vopravil. Particular thanks are due to the Italian National Statistical Institute (Istat), the Russian Federation State Statistical Committee, and Statistics Netherlands for their active support of this project.

They will be taken into account in any future revision. Enrico Giovannini Chief Statistician and Director of the Statistics Directorate Organisation for Economic Co-operation and Development Carol S.
