  • THE OECD-WTO BALANCED TRADE in SERVICES DATABASE (BPM6 Edition)
    1 THE OECD-WTO BALANCED TRADE IN SERVICES DATABASE (BPM6 edition) Antonella Liberatore (OECD), Steen Wettstein (WTO)1 January 2021 Complete, consistent and balanced bilateral trade in services statistics are vital for the empirical analysis of international trade as well as for policy-making and trade negotiations. Unfortunately, such data are not readily available. This paper presents the work of OECD and WTO to build an updated version of the Balanced Trade in Services (BaTIS) dataset, a complete and consistent trade in services matrix to serve as input for the compilation of the TiVA Inter-Country Input-Output Tables and as a tool for the analysis of trade patterns in general. This second edition of BaTIS provides annual data for 2005-2019, covering 202 economies, broken down by the 12 main EBOPS 2010 service categories. This paper accompanies the dataset and describes its compilation methodology in detail, including the collection and cleaning of the reported data, the different methodologies used to estimate missing information, and the final balancing of the export and import flows. 1 This contribution reflects a description of a methodology and does not represent the position or opinions of OECD, WTO or their respective Members, nor the official position of any staff members. The definition of geographical territories in this report is merely statistical and does not imply an expression of opinion by the OECD or the WTO Secretariat concerning the status of any country or territory, the delimitation of its frontiers, its official name, nor the rights and obligations of any WTO member in respect of WTO agreements.

Using an error-correction model approach we find that on average intervention is effective in moving the real exchange rate in the desired direction, controlling for deviations from the equilibrium and short-term changes in fundamentals and global financial variables. Our results are robust to different samples and estimation methods. We find little evidence of asymmetries in the effect of sales and purchases, but some evidence of more effective interventions for large deviations from the equilibrium. We also explore differences across countries according to the possible transmission channels and nature of some global shocks.

  • Revaluation of Financial Statement Due To
    Academy of Accounting and Financial Studies Journal Volume 25, Special Issue 2, 2021 REVALUATION OF FINANCIAL STATEMENT DUE TO DEVALUATION OF CURRENCY– DOES FINANCIAL STATEMENT SHOW ACCURATE VALUE OF YOUR ORGANIZATION? Muhammad Nabeel Mustafa*, SZABIST University Haroon ur Rashid Khan, SZABIST University Salman Ahmed Shaikh, SZABIST University ABSTRACT Purpose: Debtors are current asset has a time of 120 days at max. During this time, the value of debtors gets changed. This study explores the effect of this time value of money. The objective of this research is to sight see the effect of the time value of money, normal inflation, and purchasing power on the comprehensive debtors/receivable side of the balance sheet, which can be devalued if key macroeconomic factors determine the devaluation percentage of a single currency. Methodology: Concerning these significant questions of the research, we grasped a pragmatic philosophy with an inductive approach. A mono-method of qualitative based on grounded theory was endorsed, which helped to unfold a new model through qualitative data analysis. Results: A new strategy is developed, which utters three components; normal inflation, time value of money, and purchasing power revealing significant contribution in literature. The effect of these constructs was not incorporated in the financial statement, showing vague financial valuation. These constructs have a significant impact on the financial statement of any organization especially with items having time components in the balance sheet, such as receivables and payables. Research Limitations: This research is limited to only one currency i.e., Pakistani Rupee but can be implemented on any currency. Practical Implication: The strategy will help auditors to pass the adjustment entry in the balance sheet to adjust the value of the currency at the year-end.

No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. Introduction The Political Economy of Currency Choice The Political Economy of Currency Choice he exchange rate is the most important price in any economy, for it affects all other prices. The exchange rate is itself set or strongly influenced by government policy. Currency policy thereforeT may be a government’s single most significant economic pol- icy. This is especially the case in an open economy, in which the rela- tionship between the national and international economies is crucial to virtually all other economic conditions. Policymakers who have to answer, directly or indirectly, to constit- uents, such as voters, interest groups, and investors, are the ones who make currency policy. Like all policies, the choices available to currency policymakers involve trade- offs. Currency policies have both benefits and costs, and create both winners and losers. Those who make ex- change rate policies must evaluate the trade- offs, weigh the costs and benefits, and consider the winners and losers of their actions. Exchange rate policy provides an extraordinary window on a na- tion’s political economy. This is particularly true in countries whose economies are open to the rest of the world economy, because in such a situation currency policy has a profound impact on a whole range of For general queries, contact [email protected] Frieden.indb 1 10/23/2014 8:19:54 AM © Copyright, Princeton University Press.

Terms Definition Absolute Advantage (AA) The ability to produce a good at lower cost, in terms of real resources, than another country. In a Ricardian model, cost is in terms of labor only. Absolute advantage is neither necessary nor sufficient for a country to export a good. Ad Valorem Equivalent The ad valorem tariff that would be equivalent, in terms of its effects on trade, Terms price, or some other measure, to a nontariff barrier. Ad Valorem Tariff (A Tariff defined as a percentage of the value of an imported good. Percentage of Price) Adjustment Assistance Government program to assist workers and/or firms whose industry has declined, either due to import competition (trade adjustment assistance) or from other causes. Such programs usually have two (conflicting) goals: to lessen hardship for those affected, and to help them change their behavior -- what, how, or where they produce. AGOA U.S. legislation enacted May 2000 providing tariff preferences to African countries that qualify, including trade facilitation and technical assistance to producers. As of January 2016, 40 countries were listed as eligible. Several countries have had their eligibility removed and some later reinstated over the years. Anti-Dumping Measures A complaint by a domestic producer that imports are being dumped, leading to an anti-dumping duty if both dumping and injury are found in the resulting investigation.

  • Importing, Exporting and Aggregate Productivity in Large Devaluations∗
    Importing, Exporting and Aggregate Productivity in Large Devaluations∗ Joaquin Blaum.† July 2017 Abstract A standard mechanism linking large real depreciations to declines in aggregate productivity is that firms’ access to foreign inputs is restricted. Recent quantitative trade models of importing predict that the economy’s aggregate import share should decrease following a real depreciation. I provide evidence that in fact the aggregate import share increases after a large depreciation. Using Mexican micro data, I show that the increase in the overall import intensity is explained by the expansion and entry of new exporters, which are intense importers. I develop a model of joint importing-exporting and discipline it to match salient features of the Mexican micro data. I study a counterfactual devaluation and show that the calibrated model can generate an increase in the aggregate import share and compositional effects in line with the data. A model with importing only cannot generate either, and predicts a decrease in aggregate productivity that is twice as large.

  • Topic 12: the Balance of Payments Introduction We Now Begin Working Toward Understanding How Economies Are Linked Together at the Macroeconomic Level
    Topic 12: the balance of payments Introduction We now begin working toward understanding how economies are linked together at the macroeconomic level. The first task is to understand the international accounting concepts that will be essential to understanding macroeconomic aggregate data. The kinds of questions to pose: ◦ How are national expenditure and income related to international trade and financial flows? ◦ What is the current account? Why is it different from the trade deficit or surplus? Which one should we care more about? Does a trade deficit really mean something negative for welfare? ◦ What are the primary factors determining the current-account balance? ◦ How are an economy’s choices regarding savings, investment, and government expenditure related to international deficits or surpluses? ◦ What is the “balance of payments”? ◦ And how does all of this relate to changes in an economy’s net international wealth? Motivation When was the last time the United States had a surplus on the balance of trade in goods? The following chart suggests that something (or somethings) happened in the late 1990s and early 2000s to make imports grow faster than exports (except in recessions). Candidates? Trade-based stories: ◦ Big increase in offshoring of production. ◦ China entered WTO. ◦ Increases in foreign unfair trade practices? Macro/savings-based stories: ◦ US consumption rose fast (and savings fell) relative to GDP. ◦ US began running larger government budget deficits. ◦ Massive net foreign purchases of US assets (net capital inflows). ◦ Maybe it’s cyclical (note how US deficit falls during recessions – why?). US trade balance in goods, 1960-2016 ($ bllions). Note: 2017 = -$796 b and 2018 projected = -$877 b Closed-economy macro basics Before thinking about how a country fits into the world, recall the basic concepts in a country that does not trade goods or assets (so again it is in “autarky” but we call it a closed economy).
