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.     

Habit persistence and the structure of international commodity trade

The paper analyzes the commodity structure of exports and imports of nine industrialized countries, using a dynamic version of the Linear Expenditure System. The hypothesis implied by this approach is that the structure of commodity trade can be explained by a combination of habit persistence and constant marginal expenditure shares. Application of the model to the trade composition of nine countries shows that there are considerable differences in the strength of habit persistence across countries and across commodity groups as well as between exports and imports. These are crucial for the explanation of the associated expenditure and price elasticities.     

外资流入对外贸影响的实证分析

蒙代尔认为,如果满足要素价格均等化的条件,贸易与投资具有完全替代作用,而后来的一些学者则认为资本要素的国际流动或者直接投资与商品贸易之间不仅存在替代性,而且在一定条件下存在互补关系。应该说这两种关系在不同发展阶段、不同国家、不同的条件下是表现不一的。本文主要通过近10年来我国外商投资与对外贸易的实证教据分析,侧重说明外商直接投资与对外贸易的互补关系,分析FDI流入对我国贸易的带动作用。     

AUSTRALIAN COMMODITY EXPORT PASS-THROUGH AND FEEDBACK CAUSALITY FROM COMMODITY PRICES TO THE EXCHANGE RATE

Commodity export pass-through is examined for Australia in an attempt to determine whether Australia is a price-taker in its commodity export trade. This is undertaken for seven categories of Australia's main commodity good exports. We also determine if there is feedback causality from particular world commodity prices back to the exchange rate as is often hypothesised for commodity good intensive exporting countries. It is found that Australian commodity good export pass-through is complete for the goods which are relatively less important in its export trade but is incomplete (although high) for the goods which are most important in its export trade. There is significant feedback causality to the exchange rate from the world price of coal and wheat, two of Australia's most important commodity good exports over the 1980s and early 1990s.     

Do oil price changes really matter to the trade balance? Evidence from Korea-ASEAN commodity trade data

The contribution of this article is to assess the effect of oil prices have on the trade balance in the framework of bilateral commodity trade data between Korea and each of the four ASEAN member countries—Indonesia, Malaysia, Singapore, and Thailand. To examine this subject thoroughly, we first assume the effects of oil price changes to be symmetric and apply the linear autoregressive distributed lag (ARDL) method to the subject. We find that the price of crude oil indeed has an important role in affecting Korea's trade balance with those four ASEAN economies in both the long- and short-run. We then separate oil price hikes from oil price plunges and implement the nonlinear ARDL method to reveal that there is evidence that changes in oil prices appear to have asymmetric effects on the trade balance for certain products in the long- and short-run.     

Output/Endowment and Commodity/Factor Price Relationships and Welfare in a Multilateral Trade Model with Partial Factor Mobility

A multilateral model of trade with both commodity flows and partial mobility of factor flows is set up. This model is used to develop factor endowment/output relationships as well as commodity/factor price relationships. Welfare consequences of these parametric shifts are examined. The model is built on the customs union framework which involves three countries and both commodity and factor flows. Owing to spillover effects in multilateral trade models, many nontraditional results are obtained. Many developed countries accept skilled and unskilled migrants from other countries. These migrants are generally accepted on a quota system. Moreover, it has been established that an increase in the migrant quota in the presence of factor mobility may raise or lower the output and welfare in the country not receiving migrants. In fact it is shown that the non‐migrant receiving country could be immiserized due to loss of capital. The main message of this paper is that in a multilateral trade framework there exist international spillover effects which must be taken into consideration in national policymaking.     

Economic Growth,Terms of Trade and Welfare in an Open Monetary Economy*

The authors investigate the impact of growth on terms of trade, absolute prices and welfare using a two-country, monetary model. Under flexible exchange rates export-biased growth would lead to a decline in the terms of trade if the two countries are ‘similar’. Under fixed exchange rates a weaker condition than the barter condition of export-biased growth is sufficient, namely, for the import commodity the demand creating effect of growth dominates the supply effect while for the exported commodity the opposite holds. Secondly, substitutability between money and commodities indicates that no necessary relation holds between the terms of trade and the trade balance. Thirdly, the introduction of money creates a real balance effect so that decline in terms of trade is no longer a necessary (or sufficient) condition for immiserization. Finally, the paper concludes by questioning two policy conclusions drawn in earlier models: one, that the declining terms of trade of less developed countries was due to a bias in the growth strategy and, two, that monetary models of trade support the ‘monetarist’ proposition that growth and a deteriorating trade balance can only co-exist if the domestic monetary policy is nonneutral.     

Terms of trade and the exchange rates of New Zealand and Australia

Effects of the terms of trade on the bilateral exchange rate of New Zealand and Australia and of each of these countries with the USA are evaluated. There is strong evidence of cointegration of the exchange rates and a ration of the respective national price levels when the relative terms of trade of the countries are included in dynamic models. While evidence that the long-run equilibrium relationships satisfy purchasing power parity is mixed, relative improvement of a country's terms of trade results in real appreciation of its currency in all cases. The terms of trade are also found to be exogenous for the parameters of the long-run New Zealand–Australia exchange-rate equilibrium.     

The transmission of world commodity prices to domestic markets under policy reforms in developing countries

This paper examines the degree to which world price signals have been transmitted into domestic prices for eight countries and ten commodities, a total of 31 country/commodity pairs. The main characteristic of these countries was that they all undertook substantial policy reforms during the mid‐1980s to early 1990s. The paper investigates the effect of reforms on the speed at which signals were transmitted to domestic markets and on the extent of price transmission. We find that Chile, Mexico, and Argentina are the only countries whose domestic commodity markets were integrated with world markets. For the remaining cases (Ghana, Madagascar, Indonesia, Egypt, and Colombia) in only a few country/commodity pairs is there some passthrough of world price changes. In terms of the effects of policy reforms, in the majority of the cases the hypothesis of a structural break following the reform year is rejected.     

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.     

The demise of commodity price agreements: the role of exchange rates and special interests

We derive the equilibrium joint distribution of exchange rate and commodity price in a two-country rational expectations model. The correlation between commodity price and exchange rate appears crucial for the stability of commodity markets. This result arises from the common practice to quote commodity prices in consuming countries' currency, which subjects producing countries to the currency risk. Welfare results of commodity price stabilization are obtained and facilitate the interpretation of the position taken by industrialized countries long opposed to international commodity agreements. We apply our model to the Philippines and investigate the potential effects of the International Sugar Agreement (ISA) on the various conditional volatilities of the model. We conclude on the relative ineffectiveness of these agreements in limiting fluctuations of sugar prices.     

Commodity Prices and the Terms of Trade

On combining national terms-of-trade data for developing countries with world prices of internationally traded primary commodities, it is found that variation in the world prices of three or fewer key exported commodities account for 50% or more of the annual variation in the terms of trade of a typical developing country. A considerable fraction of the variation is specific to a particular commodity and, given that the overall importance of primary commodities differs across developing countries, it is possible to account for much of the heterogeneity across them. It is concluded that commodity price fluctuations should be central features of two related literatures: studies of business cycle transmission across developing and industrialized nations, and empirical work aimed at constructing perpetual claims on developing country incomes as suggested by Shiller in 1995.     

Quotas and equilibrium relative prices in the trade restricting country

This paper is concerned with the effects of international trade restriction through quotas. It is shown that a casual relationship exists between the fraction of licences distributed domestically, the terms of trade, and the domestic relative price of the importable.     

Exchange rate changes and endogenous terms of trade effects in a small open economy

This paper shows that the small-country assumption of dependent-economy models is unlikely to hold for many of the cases in which this class of models is used, for example, in the analysis of a terms of trade shock in the “commodity currency” models. When a shock affects most or all of the small countries exporting a commodity, the combined exchange rate effects will result in endogenous terms of trade changes even for those countries too small to individually affect world markets. The paper also explores the possible implications of these secondary terms of trade changes for the dependent-economy models.     

Movements of relative agricultural prices in sub-Saharan Africa

Movements of relative agricultural prices in 20 countries insub-Saharan Africa between 1973 and 1999-95 are investigated.Changes in the net barter terms of trade of the agriculturalsector are compared with international terms of trade movements.Movements in prices received by cocoa, coffee, cotton and teafarmers are compared with unit export prices and with indicatorsof production costs. World price movements for the same commoditiesare compared with unit export prices of major exporting countries.A similar analysis is undertaken for cereals, where producerprices are compared with unit import prices and with cost indicators.Possible factors which affect these relative price movementsare discussed with special emphasis on the role of alternativepolicy regimes. Empirical findings suggest that conventionalviews on the anti-farmer bias of African policies till the 1980sare questionable and the recent liberalisation of agriculturalmarkets in Africa have not generated farmer-friendly outcomes.     

International business cycles and the relative price of investment goods

Abstract Is the relative price of investment goods a good proxy for investment specific technology? We model this relative price in a flexible price international economy with two fundamental shocks, namely, the total factor productivity (TFP) shock and the investment‐specific technology (IST) shock. We show that the one‐to‐one correspondence between the IST shock and the relative price of investment goods breaks down in an international economy because of the short‐run correlation between the terms of trade and the relative price of investment goods. The data congruent negative correlation between the investment rate and the relative price of investment goods thus does not necessarily reflect decline in investment frictions (rise in IST), as suggested by many studies. A calibration experiment with the US data demonstrates that such an inverse relation between rate of investment and the relative price of investment goods basically reflects the positive effect of TFP on the terms of trade for a broad range of economies where the home bias in consumption exceeds investment and there is a sizable adjustment cost of investment.     

International risk sharing and commodity prices

Abstract Cole and Obstfeld (1991) exposited a classic result where equilibrium movements in the terms of trade could make ex ante risk‐sharing arrangements unnecessary: a unity elasticity of substitution across goods and production specialization. This paper extends their model to N countries and M commodities (N > M). Here the terms of trade provides insurance against commodity‐specific shocks, not country‐specific shocks. Using commodity‐level production data at the national level and world commodity prices, we document significant terms of trade variability and positive responses of nation‐specific production to terms of trade improvements. The endogenous terms of trade insurance mechanism highlighted in CO is virtually non‐existent.     

Joint outputs and real wage rates

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares.     

Dynamics of the Relationship Between the Terms of Trade and the Trade Balance in Developing Countries of Asia,Africa and Latin America

The objectives of this study are to examine the relationship between the terms of trade and trade balance to GDP ratios for a large number of developing economies using data on barter terms of trade, real exchange rate and trade balances. The literature on the subject postulates J-curve or S-curve between terms of trade and trade balance and we examine whether there is any evidence of a J-curve or S-curve relationship in time series data over the period 1970–1999. We find that for a few economies in Asia, Africa and Latin America, the existence of a S-curve is supported. However, for a large number of countries, neither a strict J-curve nor S-curve relationship holds.

     

Do Preferential Rules of Origin Reverse Trade Creation and Trade Diversion?

Restrictive preferential rules of origin (PROOs) moderate the ‘trade diversion and trade creation’ effects of free trade agreements (FTAs). Moderation effects occur because restrictive PROOs reverse the increase in the relative price of non-member country goods initially caused by FTAs. Such a reversal arises because high compliance costs associated with restrictive PROOs lead to a lower utilization of tariff preferences by member countries. With a lower utilization, the increase in the relative price of non-members country goods would be smaller than it could have been with a full utilization. Thus, restrictive PROOs will lead to less than full trade diversion from non-members to member countries, and less than complete trade creation to member countries. This paper infers the effect of restrictive PROOs on intra-regional trade from the estimated parameters of the revenue function, on the presumption that trade diversion refers to a decrease in the elasticity of substitution between import sources, and that trade creation refers to a difference between the change in import price elasticity and the trade diversion effect. Empirical results support the conjecture that restrictive PROOs move in the opposite direction of FTAs partly undoing the trade diversion and trade creation effects of FTAs.
