REAL GROSS DOMESTIC INCOME,RELATIVE PRICES,AND ECONOMIC PERFORMANCE ACROSS THE OECD

This paper uses OECD data to examine changes in labor productivity, real gross domestic product (GDP) and real gross domestic income (GDI), economic aggregates, and relative economic growth over time. Real GDI combines changes in production (real GDP) with a trading gain derived from relative price changes. The paper considers two sources of trading gains: the terms of trade, and the real exchange rate. For OECD countries, the terms of trade is the more important price ratio, making a contribution to real income growth that is, on average, an order of magnitude larger than the real exchange rate. Over long time periods, the most important source of real income growth is changes in production. Over shorter time horizons, however, the trading gain can make noteworthy contributions. Changes in aggregates like real private consumption, or the relative economic performance of nations, are shown to be particularly dependent on the trading gain during the large swings in resource prices that occurred post‐2002.     

Decomposing growth in revenues and costs into price,quantity and total factor productivity contributions

This article employs the superlative Fisher and Törnqvist indexes for exact decomposition of growth in nominal revenues and costs. The findings confirm the well-known result that these indexes very closely approximate each other, implying that the mathematically simpler and computationally easier Törnqvist is the more practicable index. Moreover, this article's nominal growth decomposition yields all the results from the more common real growth decomposition and is also more informative for policy purposes. Application to the US agricultural sector during 1948–2001 shows that of the 3.31% average annual growth in revenues, TFP growth contributed 1.90 percentage points (pct. pts.); growth in output prices added 1.43 pct. pts.; while growth in input quantities contributed?–?0.02 pct. pts. (i.e. fewer inputs). Therefore, real output growth (or revenue growth less output price growth) was 1.88 pct. pts., revealing that TFP's 1.90 pct. pts. growth contribution was fully responsible for real output growth with fewer inputs. Since revenues measure incomes, these results suggest that policy should focus more on measures to foster TFP growth than on specific price or quantity instruments to enhance income growth.     

Free trade: what are the terms-of-trade effects?

Changes in trade policy affect a nation’s economic welfare through terms-of-trade and volume-of-trade effects. A move to global free trade would imply higher world economic welfare equal to the sum of all nations’ volume-of-trade, or efficiency, effects. Since the sum of the terms-of-trade effects across all nations is zero, terms-of-trade effects are contentious. Konishi, Kowalczyk and Sjöström (2003) have shown that if customs unions do not affect trade with non-member countries, immediate global free could be achieved if free trade were proposed together with international sidepayments equal to the terms of trade effects. How large would these terms of trade effects, and hence transfers, be? This paper presents estimates from a simple computable general equilibrium model of a world economy of perfect competition. We show that, in some cases, terms-of-trade effects are small compared to efficiency gains, and transfers are not necessary for free trade. In other cases, terms-of-trade gains may account for more than 50% of a country’s gains from free trade and transfers could be large.     

Estimating the true cost of living for households with different incomes using data from Taiwan

This empirical study investigates why the true costs of living for different income groups in Taiwan as measured by the superlative Törnqvist price index have grown dissimilarly over the sample period. Specifically, it shows that using the aggregate Cost of Living (COL) estimates for the entire households as is commonly practiced would produce noticeable group bias effect in measurement. Also the magnitude of the commodity substitution bias in the conventional Consumer Price Index (CPI) is found to be positively related to household income in general. Because of the presence of these two biases, the true COL for households belonging to the two ends of the income spectrum is found to be over-estimated. This article is therefore in full agreement with Arrow's proposition that an alternative and separate set of price index be constructed.     

Trade liberalisation and exchange rate pass-through: the case of textiles and wearing apparels

Studies on the relationship between exchange rates and traded goods prices typically find evidence of incomplete pass-through, usually explained by pricing-to-market behaviour. Although economic theory predicts that incomplete pass-through may also be linked to the presence of non-tariff barriers to trade, variables reflecting such a link is rarely included in empirical models. In this paper, we estimate a pricing-to-market model for Norwegian import prices on textiles and wearing apparels, controlling for non-tariff barriers to trade and shift in imports from high- to low-cost countries. We apply the cointegrated VAR approach and develop measures of foreign prices based on superlative price indices (including the Törnqvist and Fischer price indices) and a data calibration method necessary to approximate relative price levels across countries. Our measures of foreign prices thereby account for inflationary differences and varying import shares and price level differences (known as the China effect) among trading partners. We show that these measures of foreign prices, unlike standard measures used in the pricing-to-market literature, are likely to produce unbiased estimates of pass-through. Once the China effect is controlled for, we find little evidence that pass-through has changed alongside trade liberalisation.     

Malmquist and Törnqvist productivity indexes: returns to scale and technical progress with imperfect competition

Caves, Christensen and Diewert proposed a method for estimating a theoretical productivity index for a firm using Törnqvist input and output indexes, augmented by exogenous estimates of local returns to scale. However, in order to implement their method, they assumed that the firm maximized revenue in each period, conditional on the observed input vector in each period, taking output prices as fixed. This assumption is not warranted when there are increasing returns to scale. Thus in the present paper, it is assumed that the firm solves a monopolistic profit maximization problem when there are increasing returns to scale and the results of Caves, Christensen and Diewert are modified in accordance with this assumption.     

Does the distinction between gross and value‐added exports matter? An empirical investigation of export elasticities

This study uses bilateral U.S. export data from the OECD’s Trade in Value‐Added database to estimate and compare elasticities for three distinct export measures: conventional measures of gross exports, domestic value added in gross exports, and value‐added exports. It finds little evidence of significant differences in the income elasticities across the three export measures or in the price elasticities of gross exports and domestic value added in gross exports. However it finds a significantly higher price elasticity for value‐added exports, suggesting that conventional price elasticity estimates may underestimate the impact of a real dollar depreciation on U.S. exports of value added.     

Industry-level emission trading between power producers in the EU

This paper investigates how restrictions for emission trading to the energy-intensive power sector will affect the magnitude and distribution of abatement costs across EU countries vis-à-vis a comprehensive EU emission trading regime. It is found that emission trading between European power sectors allows the harvest of a major part of the efficiency gains provided by full trade as compared to strictly domestic action. However, trade restrictions may create a more unequal distribution of abatement costs across member states than is the case for a comprehensive trade regime. The reason for this is that restricted permit trade enhances secondary terms-of-trade benefits to EU member countries with low marginal abatement costs at the expense of the other EU member states.     

Multinational taxation and international emissions trading

Many studies have shown that the activities of multinational corporations are quite sensitive to differences in income tax rates across countries. In this paper I explore the interaction between multinational taxation and abatement activities under an international emissions permit trading scheme. Four types of plans are considered: (1) a single domestic permit system with international offsets; (2) separate national permit systems without trade; (3) separate national permit systems with limited offsets; and (4) an international permit trading system. For each plan, I model the incentives for the multinational firm to choose abatement activities at home and abroad and to transfer emissions credits between parent and subsidiary. Limits on trading across countries restrict efficiency gains from abatement, as is well known. But if available offset opportunities are limited to actual abatement activities, those activities are also more susceptible to distortions from incentives to shift taxable income. Transfer-pricing rules can limit but not always eliminate these distortions. In a system of unlimited international trading, abatement is efficiently allocated across countries, but tax shifting can still be achieved through intra-firm transfer pricing. From the basis of efficiency for both environmental and tax policies, the best design is an international permit trading system with transparent, enforceable transfer-pricing rules.     

GDP Growth Accounting: A National Income Function Approach

In this paper, we provide a decomposition of GDP growth that is complete and exact for the translog national income function and for the Törnqvist index of real GDP. The contributions of changes in output quantities, factor prices and total factor productivity are identified. Special consideration is given to foreign trade, with imports treated as a negative output. Annual estimates for the United States are reported for the period 1948–98.     

Real Gross Domestic Product and the Terms of Trade

Since their inception in the early 1960s, constant price national accounts have contained a measurement inconsistency in the expenditure accounts which flows through to the production accounts. The inconsistency has the effect of excluding changes in the terms of trade (the ratio of export prices to import prices) from real gross domestic product, so that it is unequal to real gross domestic income, which includes them. In economies, such as those of Australia and Canada, that experience substantial changes in the terms of trade, a real gross domestic product excluding those effects becomes a misleading guide for macroeconomic analysis and policy.     

ACCRUED CAPITAL GAINS, PERSONAL INCOME AND SAVING IN THE UNITED STATES, 1948–1964

Capital gains are an important source of personal income in the United States but they are not included in the national accounts or the official estimate of personal income and saving. Individuals report their realized gains for tax purposes but the economic theorist would include both realized and accrued gains in income. National income theorists continue to debate whether capital gains should be included in income but, because of the many conceptual and statistical problems involved in estimating capital gains, no satisfactory estimates have been developed. Consequently, the debate has stayed mainly at the theoretical level. This paper deals with the methodology of estimating accrued capital gains. A simple analytical model is developed to estimate capital gains from data on market value and net acquisitions of an asset but the model can be adapted to incorporate asset prices directly. It is shown that the methods used for estimating accrued gains in the past are special cases of the model proposed in the paper. The model is then used for estimating gains accruing to individuals in the United States on their holdings of corporate stock, real estate and livestock during 1948–1964.
During this period accrued gains have amounted to roughly five times the realized gains reported for tax purposes; corporate stock and real estate are the most important sources of capital gains and corporate stock accounts for almost two-thirds of all accrued gains. The paper goes on to examine the implications of these estimates for the existing series on personal income and saving in the United States. The inclusion of accrued gains would increase the variance in the official estimates but personal saving is affected more than personal income. The paper concludes with an evaluation of these results and some suggestions for further research.     

Sectoral linking of carbon markets: A trade-theory analysis

The linking of emission trading systems (ETS) is a widely discussed policy option for future international cooperation on climate change. Benefits are expected from efficiency gains and the alleviation of concerns over competitiveness. However, from trade-theory it is known that due to general equilibrium effects and market distortions, linking may not always be beneficial for all participating countries. Following-up on this debate, we use a Ricardo-Viner type general equilibrium model to study the implications of sectoral linking on carbon emissions (‘leakage’), competitiveness, and welfare. By comparing pre- and post-linking equilibria, we show analytically how global emissions can increase if one of the ‘linked’ countries lacks an economy-wide emissions cap, although in case of a link across idiosyncratic sectors a decrease of emissions (‘anti-leakage’) is also possible. If – as a way to address concerns about competitiveness – a link between the EU ETS and a hypothetical US system is established, the partial emission coverage of the EU ETS can lead to the creation of new distortions between the non-covered domestic and international sector. Finally, we show how the welfare effect from linking can be decomposed into gains-from-trade and terms-of-trade contributions, and how the latter can make the overall effect ambiguous.     

Monetary policy shocks and productivity measures in the G-7 countries

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.

Household Satellite Account for France

We estimate in a household satellite account (HHSA) the value of French domestic production in 2010 and 1998, using the input method and following Eurostat's recommendations. In line with previous studies, we find that extending the system of national accounts (SNA) frontier of production to domestic activities (house chores, cooking, care …) has a sizeable effect on key macroeconomic indicators (+33 percent GDP, ?5 p.p. GDP growth, +50 percent disposable income, +58 percent consumption, and ?10 p.p. of purchasing power growth). We conduct a sensitivity analysis to various methodological issues which have not yet been settled by an international benchmark. Quantitatively, the two most important issues are the boundary of household production—we favor a relatively narrow definition—and the use of a gross or a net wage—we prefer gross wage‐. However, estimates are much less sensitive to otherwise greatly debated issues such as which substitute wage to use.     

A COMPARISON OF SOME SHORT-CUT METHODS OF ESTIMATING REAL PRODUCT PER CAPITA

Several recent studies of short-cut estimates comparing real income (on a purchasing power basis) of countries are reviewed, including methods comparing real income based on indicators, like electricity consumption. New estimates are presented for 101 countries which had a tradition of conventional national income estimates in 1965, and for 40 countries without extended national income series. One conclusion from the empircial analysis was that until there exist a large number of countries for which purchasing power estimates of real income are available, it is difficult to discriminate between alternative short-cut methods using indicators, and difficult to estimate real per capita incomes of low income countries without substantial errors of estimate. The paper advocates more purchasing power estimates, and institutionalizing the collection of international prices of specified items so that abbreviated market baskets can be readily compared across countries.     

SHORT-CUT ESTIMATES OF REAL INCOME

The United Nations International Comparisons Project (ICP) has conducted in-depth purchasing-power parity (PPP) studies of the so-called "benchmark" countries (of which there were 34 in the 1975 sample). In the absence of PPP studies of the rest of the countries in the world, the ICP team has constructed "short-cut" estimates of real income (that is, income converted from domestic currency to dollars at PPP) for the nonbenchmark countries. The idea of a "short-cut" procedure for estimating real income is to run a regression of real income on nominal income (that is, income converted from domestic currency to dollars at a market exchange rate) and other variables among the benchmark countries and then to use this regression to estimate real income for the nonbenchmark countries. The most recent ICP short-cut estimates have been based on regressions of real income on nominal income and the foreign trade ratio. The present study expands the list of candidate variables that might be included in a short-cut regression. The list includes educational attainments, the share of minerals in GDP, the trade balance, the growth of the money supply, tourist receipts, and the share of nontradables in GDP. The theory underlying the inclusion of each of these variables is discussed. Regressions are run with various combinations of these variables and some short-cut estimates of real income for 76 market economies are presented.     

International Capital Mobility and the Costs of Us Import Restraints*

Abstract This paper evaluates general equilibrium welfare effects of tariffs, quotas, and voluntary export restraints under different assumptions about international capital mobility. We show analytically that, when induced terms-of-trade and rental-rate effects are considered, the qualitative influence of capital mobility on the costs of protection cannot be ascertained unambiguously. Simulation estimates for the US indicate the practical importance of capital mobility, as well as of terms-of-trade and rental-rate adjustments, in determining the ultimate welfare effects of import restraints.     

Inflation Expectations, Interest Rates and Arbitrary Income Transfers

Unexpected inflation, disinflation or deflation cause arbitrary income transfers between an economy's borrowers and lenders. This redistribution results from distorted real interest rates that are too high when price level changes are over‐predicted and too low when they are under‐predicted. This article shows that in Australia's case, inflation expectations were mostly biased upwards throughout the 1990s, according to the Melbourne Institute of Applied Economic and Social Research series and to a new derived series based on bond yields, implying that real interest rates were too high over this time. In turn, this caused substantial arbitrary income transfers from debtors to creditors, estimated to have averaged up to 3 per cent of gross domestic product over the period.
