Trading gains: terms-of-trade and real-exchange-rate effects

This paper considers alternative measures of a country's trading gains, i.e., the extra income that it earns (or loses) as the result of changes in the relative prices relevant for international trade, and which makes up the difference between real gross domestic product (GDP) and real gross domestic income (GDI). Looking at both the Laspeyres and the Törnqvist aggregation, we show that the trading gains really consist of two components, a terms-of-trade effect and a real-exchange-rate effect. Nearly all national statistical agencies, receiving no firm guidance from international organizations in this matter, merely consider the first effect, which suggests that the so-called trading-gain estimates they publish are incomplete and misnamed. Even more seriously, it implies that the corresponding measures of real GDI they derive are conceptually flawed. A straightforward way to circumvent these difficulties is to use the gross domestic final expenditure price index as deflator when computing real GDI and the trading gains. Some numerical estimates for Australia are provided as an illustration. The paper also identifies the underlying linear and Translog real GDI functions for which the Laspeyres and Törnqvist terms-of-trade and real-exchange-rate effects are exact.     

Macroeconomic effects of terms of trade fluctuations in commodity exporting advanced economies

The paper examines the impact of world commodity prices on national output and trade balances in Australia, Canada, New Zealand, and Norway, OECD economies that, unlike other advanced economies, are heavily dependent on commodity exports. Contrary to Dutch disease theory based on real exchange rate adjustment, it highlights the relative price effects of terms of trade (ToT) changes on gross domestic product and net exports with reference to the experience of this unique set of OECD countries. The econometric analysis verifies key predictions of this alternative perspective that ToT fluctuations should (i) have no significant short-run impact on GDP and that (ii) due to relative price effects a strong positive relationship between the ToT and net exports is unlikely.     

Terms of trade and economic growth in Japan and Korea: an empirical analysis

This study examines the impact of terms of trade and terms of trade volatility on economic growth in Japan and Korea using time series data. The results of the Johansen (1988) cointegration method show that real gross domestic product (GDP) per capita and terms of trade are jointly determined. Generally, an increase in terms of trade volatility will lead to a decrease in real GDP per capita. An increase in oil price will lead to a decrease in terms of trade. The results of the generalised forecast error variance decompositions show that the important contributors to real GDP per capita are different between Japan and Korea. A favourable and a less volatile terms of trade are important for economic growth.     

Terms of trade volatility,government spending cyclicality,and economic growth

This paper presents estimates of the effects that terms of trade volatility has on real gross domestic product (GDP) per capita growth. Based on 5‐year nonoverlapping panel data comprising 175 countries during 1980 to 2010, the paper finds that terms of trade volatility has significant negative effects on economic growth in countries with procyclical government spending. In countries where government spending is countercyclical, terms of trade volatility has no significant effect on growth. Conditional on the mediating role of government spending cyclicality, the GDP share of domestic credit to the private sector has no significant effect on the relationship between growth and terms of trade volatility.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

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.     

Accounting for Growth and Output Gaps: Evidence from New Zealand

We evaluate New Zealand's macroeconomic performance over the 1967–1996 period, which witnessed numerous economic reforms. Using both index–number and econometric techniques, we decompose nominal GDP growth and the output gap into contributions from price level changes, productivity growth and changes in factor utilisation. Changes in domestic prices accounted for four–fifths of the growth in nominal GDP, while capital accumulation and employment growth were the most important factors determining real–output growth. Deviations in the domestic price level around its long–run trend contributed most heavily to changes in the nominal output gap. The real gap was influenced in any year variously by deviations of the terms of trade and labour input from their long–run trends, as well as by productivity shocks.     

INTERNATIONAL AND INTERTEMPORAL COMPARISONS OF REAL PRODUCT IN OECD COUNTRIES A GROWTH SENSITIVITY ANALYSIS

This paper provides two new data sets for comparisons of real income in OECD countries. The first set provides adjusted real series for GDP and its components from 1960 to 1993 based on OECD 1990 purchasing power parities. The second set uses OECD PPP of different benchmark years, and interpolates these applying national price indices. Comparisons between both alternatives, Penn World Tahle Mark 5 (PWT 5) and its new version (PWT 5.6), in terms of economic growth and convergence, reveal some remarkable differences. Moreover, there are wider differences concerning the relative countries' position in GDP per capita ranking. Estimations of convergence equations based on OECD data yield a better fit than those obtained using PWT data, although there are also some significant differences between PWT 5 and PWT 5.6. Nevertheless, a very positive result is that other parameters of interest in these equations are not affected by the use of these different data sources.     

TERMS OF TRADE AND ECONOMIC GROWTH IN NINETEENTH CENTURY BRITAIN *

International trade and economic growth have been considered intimately linked in nineteenth century Britain. Conventional estimates of Britain's gross national product, however, fail to account for changes in the terms of trade and may be misleading indicators of changes in real income. Revised figures that incorporate terms of trade changes are presented here. One finding is that conventional estimates of GNP overstate growth in real income early in the century when the terms of trade deteriorated.     

Are shocks to the terms of trade shocks to productivity?

International trade is frequently thought of as a production technology in which the inputs are exports and the outputs are imports. Exports are transformed into imports at the rate of the price of exports relative to the price of imports: the reciprocal of the terms of trade. Cast this way, a change in the terms of trade acts as a productivity shock. Or does it? In this paper, we show that this line of reasoning cannot work in standard models. Starting with a simple model and then generalizing, we show that changes in the terms of trade have no first-order effect on productivity when output is measured as chain-weighted real GDP. The terms of trade do affect real income and consumption in a country, and we show how measures of real income change with the terms of trade at business cycle frequencies and during financial crises.     

China's potential future growth and gains from trade policy bargaining: Some numerical simulation results

Numerical simulation analysis of bargaining solutions is little developed in existing literature. In this paper, we use a numerical general equilibrium model which captures China and her major trading partners and examine the outcomes of trade policy bargaining solutions (bargaining over tariffs and financial transfers) over time, and then measure both absolute and relative gains to China from trade bargaining. These measurements are important for policy making. Our simulation results indicate that China's welfare gain from trade bargaining will increase over time if countries keep their present higher GDP growth rates for several decades, but there are major difference when using different bargaining solution concepts. These differences have not been noted in existing literature but have an intuitive explanation. Our results also indicate that if China jointly bargains along with India, Brazil and other developing countries with the OECD, and when we use PPP to adjust China's relative GDP size China's gain will further increase.     

The effects of economic freedom,regulatory quality and taxation on the level of per capita real income: a preliminary analysis for OECD nations and non-G8 OECD nations

This study of the impact of economic freedom, regulatory quality and the relative burden of taxation on the level of per capita real income/GDP among OECD nations over the period 2003 to 2007 adopts a modified version of the overall economic freedom index computed by the Heritage Foundation (2013), one with the fiscal freedom and business freedom indices removed. This study then provides panel least squares fixed-effects estimates for five linear specifications/models. Each nation during this time frame can be regarded either as a nation per se or as a de facto ‘economic region’ within the OECD. The analysis first focuses upon all of the OECD nations and then, as a robustness test, subsequently focuses only on non-G8 OECD member nations. The estimations in this study all provide strong empirical support for the three central hypotheses proffered here, namely: (1) the higher the overall degree of economic freedom, the higher the per capita real income (GDP) level; (2) the higher the level of regulatory quality, the higher the level of per capita real income (GDP) and (3) the higher the overall tax burden, expressed as a per cent of GDP, the lower is the level of per capita real income (GDP).     

CONCEPTS AND PROBLEMS OF CONSISTENCY IN TERMS-OF-TRADE ANALYSIS*

The debate on how to deal with changes of relative prices in national accounts has, so far, remained inconclusive, especially with regard to the question of how to measure gains from changes of terms of trade. Keeping the experiences of the 1970s in mind (i.e. substantial changes of relative prices sparked off by increased oil prices), this state of affairs is not considered tenable. On this background, the paper takes up the old debate on how to deflate figures of domestic product, total as well as by industries. It tries to argue that deflated figures should be presented not only as real product figures by industries (using the double deflation method), but also as real income figures, obtained by deflating the current-prices figures of a certain year by the same general price index. When this is done according to procedures spelled out in detail, gains/losses from changes of the terms of trade in foreign trade will show up as an integral part of the framework. In the paper, special attention is given to the concept of industry terms of trade. On the basis of simplifying assumptions (which are, however, relaxed in the final part of the paper), it is shown how the ratio of real income divided by real product of a certain industry will be proportionate to the terms of trade of the industry concerned, when the latter concept is defined in the appropriate way. Furthermore, the sum of the industry gains/losses from changes of their terms of trade will be equal to the gain/loss of the economy taken as a whole from changes of the terms of trade in foreign trade.     

Neoclassical Growth, Manufacturing Agglomeration, and Terms of Trade

This study reverses the prediction of geography and growth models that trade integration may cause income divergence. Moreover, a new dynamic welfare gain of trade openness is identified. These results are obtained from embedding a new economic geography model into a neoclassical growth model. Starting from symmetric countries, a country that accumulates more capital than the other increases its home market size, improves its terms of trade, and lowers its relative consumption price index, because trade costs drive a wedge in between relative producer and consumption price indices. Both effects in turn tend to increase its marginal revenue product of capital relative to the other country (divergence forces), while factor substitution diminishes its marginal revenue product of capital (convergence force). Reducing trade costs decreases the wedge and weakens the divergence forces, while the convergence force is unaffected. Hence, divergence is more likely with higher rather than lower trade costs.     

Oman's trade and opportunities of integration with the Asian economies

This paper investigates the determinants of trade between Oman and its major Asian trading partners in order to gauge the impact of the process of trade liberalisation. The empirical findings based on the gravity model indicate that Oman's imports from Asia are strongly determined by Asian population, Asian per capita gross domestic product (GDP), real exchange rates, distance and Oman's per capita GDP. The results also provide strong evidence that Oman's oil exports to Asia are strongly and equally determined by Asia's and Oman's population. Our findings reveal that while distance is not a friction to Oman's oil exports, it has a weak regressive effect on non-oil exports. Our results also indicate a negative but statistically insignificant effect of trade liberalisation on non-oil exports. These findings certainly have policy implications in terms of Oman–Asia trade relationship and in particular the need for more policy intervention to liberalise the non-oil exports sector so as to facilitate its wider integration within Asia.     

Convergence clustering in the Chinese provinces: New evidence from several macroeconomic indicators

In this paper, the convergence clustering in 31 Chinese provinces regarding several important economic indicators over the period 1952 to 2016 was empirically investigated. Several provincial clusters were identified in the per capita (real) gross domestic product (GDP), consumption–income ratio, retail price, and consumer price inflation rates, using a club convergence and clustering procedure. The empirical findings are as follows. First, it was found that all series of the original data contain a significant nonlinear component. Second, it was observed that there are five significant clusters for the per capita income in China. Third, it was found that there are four significant clusters for the consumption–income ratio. Fourth, it was observed that there are four significant clusters for the retail inflation rates and two significant clusters for the consumer inflation rates in China. These results will enable local and central planners to implement economic growth, savings and price adjustment policies for different groups of provinces.     

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.     

What Determines Real Exchange Rates? The Nordic Countries

The model derived in this paper yields testable implications concerning the long‐run co‐movements of real exchange rates, relative labor productivity, the trade balance and terms of trade. Countries with relatively higher output growth, trade deficits or improved terms of trade are found to have more appreciated real exchange rates, with the main channel of transmission working through the relative price of nontraded goods. Exogenous terms‐of‐trade shocks are found to be the most important determinant of long‐run movements in the real exchange rate for Denmark and Norway, while demand shocks account for most of the long‐run variance in the real exchange rate for Finland and Sweden.     

Rigid Wage,Factor Immobility and Immiserizing Growth*

In the theory of trade and growth, Bhagwati made an interesting contribution by demonstrating the proposition that growth can be welfare reducing even at constant terms of trade, whenever distortions obtain in an economic system. Batra-Scully strengthened the Bhagwati thesis and derived the conditions for growth to be immiserizing at improved terms of trade in the presence of a wage differential. In the present analysis, we show that economic expansion in a country which is characterized by factor immobility and/or factor price rigidity may not reduce the country's real income at constant or improved terms of trade. Specifically, the Bhagwati theorem, and its stronger version proposed by Batra-Scully, hold for an economy with a rigidity in factor price whether or not accompanied by factor immobility. However, growth will not lower welfare at constant or improved terms of trade if factor immobility is the only imperfection existing in the factor market.     

A Band Spectral Analysis of Exports and Economic Growth in the United States

This paper examines the role of exports in aggregate economic growth in the United States using band spectral regression. The findings reveal a predictable relationship between long-run frequency components of real export growth and real GDP growth over the post-Bretton Woods period of flexible exchange rates. The study fails to uncover a significant relationship between long-run frequency components of the terms of trade and real output. Overall, the findings support the export-led growth hypothesis, and dismiss long-run movements in the terms of trade as an important determinant of real output growth.
