The evolution of market integration in Russia

We use a statistical model of commodity trade to measure the extent of integration between regional commodity markets within Russia. Monthly time-series data on regional commodity prices spanning 1994 through 1999 indicate substantial fluctuations in integration over this period: an initial period of widespread integration gradually gave way to a period of disconnectedness in 1995 through 1997, which seems to have subsided by mid-1998. These fluctuations exhibit strong statistical relationships with a host of aggregate variables; most notably, internal integration exhibits a strong negative relationship with international trade.     

Commodity trade between Pakistan and the US: is there evidence of the J-curve?

A few studies that have attempted to estimate the short-run (J-curve) and long-run impact of exchange rate depreciation on Pakistan’s trade balance are either based on aggregate trade data between Pakistan and the rest of the world or between Pakistan and her bilateral trading partners. The findings are mixed at best. Considering the trade balance between Pakistan and the US, as one of its major partners, no significant effects have been discovered. Suspecting that the trade flows between the two countries could suffer from another aggregation bias, we disaggregate their trade flows by commodity and consider the trade balance of 45 industries that trade between the two countries. We find significant short-run effects of currency depreciation on the trade balance of 17 industries. The short-run effects last into the long run in 15 cases. The largest industry that account for more than 10% of the trade seems to benefit from real depreciation in the long run.     

The international wealth channel: a global error-correcting analysis

This article investigates empirically whether shocks to asset prices transmit into the trade balance through consumption and investment for a group of five of the world??s most industrialized countries. We refer to this transmission channel as the international wealth channel and estimate a GVAR model including 29 countries with quarterly data over the period 1981Q1?C2006Q4. Generalized impulse response functions show that after a negative stock price shock US and UK consumption decreases, followed by an improving trade balance. This pattern is also visible for France, but not for Germany and Japan. Stock price decreases are only associated with decreasing investment and an improving trade balance in the UK. For housing, we do find that a negative shock to UK housing prices decreases domestic investment and improves the trade balance. However, this pattern is not visible in the other countries. Finally, a domestic negative real exchange rate shock only has a significantly positive impact on the US trade balance.     

Oil Prices, Terms of Trade Shocks, and Macroeconomic Fluctuations in Saudi Arabia

The article investigates the sources of macroeconomic fluctuations in Saudi Arabia using structural vector autoregression methods and pays particular attention to oil prices and changes in terms of trade. Using a macroeconomic model tailored to the Saudi Arabian economy, the authors identify terms of trade, supply, balance of payments, aggregate demand, and monetary shocks. The results show that the Saudi Arabian price level, real exchange rate, and to a lesser extent output is vulnerable to terms of trade shocks. Moreover, Saudi Arabian terms of trade are driven by output, trade balance, and aggregate demand shocks. To stabilize output and the real exchange rate, Saudi Arabia ought to continue diversifying its production base and aim for a stable nominal oil price. (JEL E32 , Q43 , C22 )     

Taste Parameters as Model Residuals: Assessing the "Fit" of an Armington Trade Model

We note that calibration parameters in a multi‐country Armington trade model play a role similar to that of econometric residuals: they allow the model to fit the data exactly. We use this premise to evaluate the “fit” of a standard multi‐country computable general‐equilibrium model. We find that the model relies heavily on these parameters to explain the pattern of trade. In 33 of the 46 commodity groups we assess, modeled economic behavior explains less than 20% of the variation in bilateral trade. In a calibration‐ as‐estimation experiment, we estimate the commodity‐specific elasticities of substitution consistent with a well‐fitting model and find that they are substantially higher than widely accepted estimates.     

THE J CURVE: CHINA VERSUS HER TRADING PARTNERS

The short‐run effects of currency depreciation are said to be different from its long‐run effects. In the short run, the trade balance deteriorates and improvement comes after some time; hence, the J‐curve phenomenon. Previous studies that tested the response of the trade balance to exchange rate changes in China employed aggregate trade data and provided mixed results. Indeed, most of them concluded that real depreciation has no long‐run impact on the Chinese trade balance. In this paper, we disaggregate the data by country and using recent advances in time series modelling estimate a trade balance model between China and her 13 major trading partners. We show that real depreciation of the Chinese currency has a favourable impact on her trade balance with a few partners, especially the USA. Not much support is found for the J‐curve hypothesis.     

Bilateral J-curve between the UK vis-à-vis her major trading partners

Currency depreciation is said to worsen the trade balance first before resulting in an improvement, yielding a short-run pattern labelled the J-curve phenomenon. While early studies tested the J-curve by using aggregate trade data, a few recent studies have employed bilateral data, mostly between the US and her major trading partners. In this paper we extend the literature by considering the experience of the UK. We test the phenomenon between the UK and her twenty major trading partners by employing data over 1973Q1–2001Q3 period. In most instances, we find no support for the J-curve in the short-run. In the long run, only in five cases has the exchange rate had significant impact on the bilateral trade balance.     

Optimising and Non‐optimising Balance of Trade Models: A Comparative Evidence from India

This study estimates and compares the competing optimising and non‐optimising balance of trade models using Indian data. The results obtained from the optimising model suggest that the prices relative to user cost of capital and the real wealth lead to a deterioration, while the real capital stock results in an improvement in trade balance. The estimates of conventional non‐optimising balance of trade model show the significant effect of domestic income and real exchange rate and the insignificant effect of world income on the balance of trade. The error correction models reinforce the long run estimates and show the significant effect of lagged equilibria on the balance of trade. The non‐nested hypothesis tests provide mixed evidence for the preference of one model over the other. The J test suggests that the optimising model outperforms the non‐optimising model, while the F test shows that both these models are acceptable in explaining the balance of trade.     

S-Curve at the industry level: evidence from US–UK commodity trade

Backus et al. in (Am Econ Rev 84(1): 84–103, 1994) found that the cross-correlation function between terms of trade and trade balance resembles the letter S and labeled it the S-curve. Support for S-curve is rather weak in some cases, most notably US when aggregate trade data are used. Empirical regularities based on aggregate trade data may suffer from a potential bias stemming from aggregation. Indeed, by employing US bilateral trade data excellent support for the S-curve is recovered. The support, however, was rather weak at the level of US–UK bilateral trade. Suspecting aggregation bias again, we employ US–UK trade data at the industry level and find overwhelming support for the S-curve. Furthermore, commodity attributes play no role. Valuable comments of an anonymous referee are greatly appreciated. Any error, however, is ours.     

How responsive are trade flows between Malaysia and China to the exchange rate? Evidence from industry data

This paper investigates the impact of currency depreciation on bilateral trade between Malaysia and China, especially how a real depreciation of ringgit against the yuan on each industry’s inpayments and outpayments affect the trade balance. We employ disaggregated quarterly data on import and export for 52 industries over the period 1993Q1 to 2012Q4. The results from the bounds testing approach to the cointegration and error-correction model reveal that the real bilateral exchange rate has short and long-run effects on the inpayments and outpayments of the industries. However, the short-run effects shift into the long run in 14 out of 35 industries in the inpayment models and 17 out of 44 industries in the outpayments models. Most of these are small industries producing intermediate goods. According to the ML condition, the depreciation of ringgit against yuan improves Malaysia’s trade balance with China in these industries.     

Exchange market pressure and primary commodity – exporting emerging markets

This paper studies short-term sensitivity between exchange market pressure and various domestic and external factors in primary commodity-exporting emerging markets. The paper focuses on the top country-commodity groups in sugar, cereal, fuels, ores and coffee during the pre-peak and post-peak commodity price periods across floating and pegged exchange rate regimes, using the price of crude oil as a general benchmark. Employing a panel model and panel VAR analysis, the paper finds the heterogeneity of response patterns unique to country-commodity groups and exchange rate regimes. According to the results, in flexible regimes, volatility occurs via the foreign exchange market, interest rates, and domestic credit cycles, feeding into the social costs for structurally weaker economies. Hard exchange-rate pegs often result in a drain on international reserves as the terms of trade deteriorate following post-price peaks, leading to unpopular depreciation. These results accentuate concerns over uneven international trade patterns, an open economy’s short-term foreign exchange policy, and speculative capital flows. Such sensitivity has broad implications for macroeconomic balance and the sustainability of implied exchange rate targets in the presence of a foreign exchange constraint across emerging markets.     

South African trade policy mattersTrade performance and trade policy*

South African trade policy has exerted a major influence on the composition and aggregate growth of trade. In the Apartheid period, South Africa developed a comparative advantage in capital‐intensive primary and manufactured commodities partly because of its natural resource endowments, but also because the pattern of protection was particularly detrimental to exports of non‐commodity manufactured goods. By contrast, trade liberalization from 1990 not only increased imports, but by reducing both input costs and the relative profitability of domestic sales also boosted exports. This evidence suggests that additional trade liberalization and policies that afford South African firms access to inputs at world prices could well be part of the strategy to enhance export diversification.     

Analysing Comparative Advantage and Competitiveness: An Application to Australia's Textile and Clothing Industries

Australia's comparative advantage and competitiveness in textile and clothing (TAC) industries are analysed, using Balassa's revealed comparative advantage index and Vollrath's measures of competitiveness. The analysis based on Balassa's indices shows that Australia has a strong comparative disadvantage in textiles and clothing as aggregate commodity groups, but there is comparative advantage in sub–categories of 'special textile products', 'floor coverage, tapestry etc', and 'fur clothing'. The analysis based on Vollrath's indices shows that Australia is not competitive in the world market with respect to aggregate commodity groups of textiles and clothing. Grubel–Loyd index of intra–industry trade was calculated for seven categories of textiles and two categories of clothing. The results show a rising trend in intra–industry trade in some of these categories of TAC products, implying that Australia increasingly exports and imports differentiated TAC products. Australian TAC industries may look to further promote exports of their products in the global market through increased product differentiation and improved quality and design.     

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.     

Aggregate Fluctuations with National and International Returns to Scale*

Cyclical movements in aggregate output, factor inputs, and productivity are all positively correlated across countries. This article proposes a model in which positive cross‐country correlations of these variables result from increasing returns to the world‐wide variety of intermediate goods even if technology shocks are purely country‐specific. The model also accounts for the observed positive relationship between bilateral trade volume and international comovements. Positive comovements can also arise with constant returns to variety, but only if technology shocks are themselves strongly correlated. The combination of constant returns and common shocks, however, tends to generate procyclical fluctuations of the trade balance.     

Adjustment costs and factor demands in Canadian manufacturing industries

This paper examines whether there is a relationship between the commodity terms of trade (the price of primary commodities relative to the price of manufactures) and the net barter terms of trade of 42 Sub-Saharan African countries. For most countries, there is little evidence of a stable, long-run relationship between the two terms of trade series. Accordingly, the practice in the literature of proxying for movements in any given country's terms of trade by using an aggregate index of relative commodity prices is inappropriate, and is likely to engender misleading policy conclusions.     

The S‐curve Dynamics of US Bilateral Trade*

A few studies in dynamic general‐equilibrium setting have argued that the trade balance is negatively correlated with current and future movements in the terms of trade but positively correlated with past movements, hence the S‐curve phenomenon. Using aggregate trade data and the terms of trade has not provided strong empirical counterpart. However, in this paper, when we disaggregate the trade data between the US and her trading partners we find stronger results in support of the S‐curve.     

Trade and Tradability: Exports, Imports, and Factor Markets in the Salter-Swan Model

We extend the Salter-Swan model to include both factor markets and semi-traded goods. In our model, changes in relative factor prices depend on changes in world commodity prices, factor endowments, and the trade balance. In contrast, only changes in world commodity prices can affect factor prices in the neoclassical trade model. The inclusion of semi-traded goods weakens the magnification effect in both the Stolper-Samuelson and Rybczynski theorems. When imports and domestic goods are poor substitutes, a characteristic of some commodities in developing countries, the sign of the Stolper-Samuelson theorem is reversed.     

The J-curve: evidence from commodity trade between US and China

In testing the short-run (J-curve effect) and the long-run effects of currency depreciation on the trade balance many researchers have used either trade data between one country and the rest of the world or between one country and another trading partner. Both groups are said to suffer from aggregation bias. To reduce the bias, in this article we consider trade data between one country (the US) and her trading partner (China) disaggregated by commodity. We use imports and exports of 88 industries (2-digit and 3-digit classifications) and cointegration analysis to show that the trade balance of at least 34 of the industries react favourably to real depreciation of the dollar. The J-curve effect is detected in 22 industries. Furthermore, most of these industries that are sensitive to currency depreciation are durable commodity groupings.     

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.
