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.     

The Malaysian Real Trade Balance and the Real Exchange Rate

The cointegration technique is used to examine the long‐run and short‐run relationships between the real Malaysian trade balance with the real exchange rate, domestic and world incomes. The results suggest that a real ringgit exchange rate depreciation improves the trade balance in the long run. World and domestic incomes are also found to be important determinants of trade balance. The significance of world income on trade balance indicates that Malaysia is prone to external shocks. An error‐correction model is then estimated to study the short‐run dynamics of the effects of exchange rate. The impulse response analysis shows that the effect of exchange rate on the trade balance lasts for about three years. A devaluation of ringgit will initially improve the trade balance, albeit small, after which the trade balance starts to deteriorate, and then improves again suggesting that there exists a delayed J‐curve.     

THE J‐CURVE AT THE INDUSTRY LEVEL: EVIDENCE FROM TRADE BETWEEN THE US AND AUSTRALIA*

Previous studies that tested the J‐curve phenomenon for Australia used trade data either between Australia and the rest of the world or between Australia and its trading partners on a bilateral basis. They were unable to find support for the J‐curve in the short run nor any significant relation between the trade balance and the exchange rate in the long run. In this paper we disaggregate the data between Australia and its second largest trading partner, the US, and consider the trade between 108 industries. Using annual data over the 1962–2003 period and bounds testing approach to cointegration and error‐correction modelling, we are able to discover short‐run effects of currency depreciation on the trade balance in 64 industries. The long‐run and positive effects were only evidenced in 35 cases, supporting the J‐curve.     

A nonlinear approach to the U.S.–Australia commodity trade and the J‐curve: Evidence from 123 industries

The application of nonlinear models and asymmetric analysis have recently proven to yield results that are superior to those of the linear and symmetric analysis. However, the new approaches in testing the J‐curve between Australia and the rest of the world or between Australia and her trading partners such as the United States did not yield any significant outcomes. Suspecting that those results suffer from aggregation bias, we apply new methods to the trade flows of 123 industries that trade between the United States and Australia and give evidence of an asymmetric J‐curve in 28 industries. Furthermore, we find short‐run asymmetric effects of exchange rate changes on the trade balance of almost all studies, short‐run impact asymmetric effects in 27 industries and significant long‐run asymmetric effects in 56 industries. Our findings are industry‐specific.     

The J‐Curve: Evidence from Fiji*

This article provides new evidence on both long run and short‐run determinants of trade balance for Fiji and investigates evidence of J‐curve adjustment behaviour in the aftermath of a devaluation. We adopt a partial reduced form model that models the real trade balance directly as a function of the real exchange rate and real domestic and foreign incomes. Cointegration analysis is based on a recently developed autoregressive distributed lag approach—shown to provide robust results in finite samples. The long run elasticities are also estimated using a dynamic ordinary least squares approach and the Fully Modified Ordinary Least Squares (FM‐OLS) approach. Amongst our key results we find that there is a long‐run relationship between trade balance and its determinants. There is evidence of the J‐curve pattern; growth in domestic income affects Fiji’s trade balance adversely while foreign income improves it.     

The Bilateral J‐Curve in Australia: A Nonlinear Reappraisal

Since the introduction of error‐correction and cointegration techniques, the J‐curve effect implies an initial short‐run deterioration of the trade balance, followed by improvement later due to currency devaluation. In a previous study of Australia’s bilateral trade, with each of her 23 partners, using the linear Autoregressive Distributed Lag (ARDL) approach we found the J‐curve effect in the model with the United Kingdom only. However, after incorporating the ARDL model that allows for nonlinear adjustment of exchange rate changes, we found the effect on four more partners – all asymmetrically. Furthermore, we document short‐run asymmetry in exchange rate changes in almost all models; short‐run adjustment asymmetry, and impact‐asymmetry in almost half of the models.     

Long‐run Lunacy,Short‐run Sanity: a Simple Model of Trade with Labor Market Turnover*

It is often argued that international trade is all about long‐run relationships. In this paper, we argue that this view is flawed when factor markets are characterized by turnover. Toward that end, we provide a simple dynamic model of trade with labor market turnover and show that the relationship between the economy's short‐run and long‐run behavior is more complex than in traditional trade models. For example, in the short run, the economy may produce outside of its long‐run frontier. We show that focusing on long‐run relationships can lead one to draw faulty policy conclusions, while focusing on its short‐run behavior restores sanity. The implication is that in the presence of factor market turnover, international trade issues can only be understood by studying the entire dynamic path of the economy. Long‐run relationships should be ignored.     

Offshoring and skill overlap: An empirical investigation

Conventional international trade theory predicts that bilateral offshoring flows will be highest when two countries have very different relative factor endowments. In contrast, the new trade theory contends that offshoring is more likely to exist when countries’ relative factor endowments are similar. This paper empirically tests the relationship between offshoring and relative factor endowments, measured by the skill overlap index between two countries and finds evidence that there is an inverted U‐shape relationship. Our empirical results predict that the rise in educational attainment in China will motivate U.S. multinationals to send their tasks to China in the short run; over the long run, however, U.S. multinationals will have fewer incentives to send their tasks to China. This finding sheds new light on the current trade tensions between the United States and China and has implications for trade policy.     

The bilateral J‐curve: Canada versus her 20 trading partners

There is a common belief that currency depreciation worsens the trade balance in the short run and improves it in the long run resulting in the so called J‐curve phenomenon. Early studies employed aggregate data and provided mixed results. Recent studies, however, have employed disaggregated data to remove any aggregation bias from their analysis. In this article we consider the Canadian experience and test the phenomenon between Canada and her 20 major trading partners. Using quarterly data and the bounds testing approach to cointegration, and error‐correction modelling we were able to provide support for the J‐curve in 11 out of 20 cases.     

Trade liberalization,firm entry,and income inequality

This paper examines the short‐ and long‐run effects of trade liberalization via tariff reductions on income inequality in an economy, which is characterized by an imperfectly competitive urban manufacturing sector and a perfectly competitive rural agricultural sector. Tariff reductions reduce domestic output in the importable urban manufacturing sector, leading to shifts of capital from the urban sector to the rural agricultural sector. This can narrow the wage gap between skilled and unskilled labor in the short run. However, the lowered capital cost attracts new firms, and subsequently excessive entry of firms, to the urban manufacturing sector. This firm entry effect can mitigate the favorable effect of tariff reductions on wage inequality in the long run. Empirical study confirms the findings.     

Currency fluctuations and the French–U.S. trade balance: evidence from 118 industries

The impact of currency depreciations on trade has inspired a large body of research. Recent studies have examined industry-level trade, often using cointegration analysis, finding that a significant fraction of industries respond positively to devaluations. Oftentimes, adjustment lags result in a “J curve” effect, where devaluations hurt the trade balance temporarily. This study examines the specific case of trade between the United States and France, but finds that these flows are less sensitive than has been shown for other country pairs. Only 30 of 118 industries see increased trade balances after a dollar depreciation, and virtually none follow any type of a “J curve.” Certain industry sectors are more sensitive than others, however. Examining the SITC classifications of those 30 industries, we find that many of them are clustered in the SITC 700 (Machinery and Transport Equipment) and 800 (Miscellaneous Manufactured Articles) categories. In particular, clothing and footwear, as well as electrical equipment, are particularly affected.     

IMPACT OF EXCHANGE RATE UNCERTAINTY ON COMMODITY TRADE BETWEEN THE US AND AUSTRALIA*

Exchange rate volatility is said to have negative or positive effect on trade flows. Previous studies that considered the impact of exchange rate uncertainty on the trade flows of Australia employed trade data either between Australia and rest of the world or between Australia and her few major trading partners. They were unable to discover any significant impact. In this paper when we disaggregate trade data by commodity between Australia and one of her major trading partners, the US, we find exchange rate volatility to have short‐run effects on trade flows of most industries. However, the short‐run effects last into long run, only in limited cases, though more in export commodities than import ones.     

The Economic Agenda: a View from the US

The paper surveys the agenda needed to restore noninflationary growth in industrial countries. The role of fiscal policy as short‐run stimulus both on the spending side and on the tax side is discussed. The author comments on trade, specifically the new trade round, and international finance. Long‐run fiscal imbalances due to aging are analyzed. The role of fiscal institutions such as the European Growth and Stability Pact, the Japanese bad‐loan problem, and structural problems are put into the perspective that advanced economies should nurture their reforms globally so as to provide successful examples of reforms and prove helpful trading partners.     

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

An Eaton–Kortum model of trade and growth

We combine a multi‐country, continuum‐good Ricardian model of Eaton and Kortum (2002) with a multi‐country AK model of Acemoglu and Ventura (2002) to examine how trade liberalization affects countries' growth rates and extensive margins of trade over time. Focusing on the three‐country case, we obtain three main results. First, a permanent fall in any trade cost raises the balanced growth rate. Second, trade liberalization increases the liberalizing countries' long‐run fractions of exported varieties to all destinations. Third, the long‐run effects of trade liberalization are different from its short‐run effects, which can reverse the welfare implications of the static Eaton–Kortum model.     

Wage Inequality,Increased Competition,and Trade Liberalization: Short Run vs Long Run

This paper examines the impact of increased competition and trade liberalization on skilled–unskilled wage inequality in the short run as well as the long run. It is shown that an increase in the number of firms in the producer services sector increases wage inequality in the short run even if the income shares of capital in the industrial and agricultural sectors were identical. A decrease in the services sector's fixed cost decreases wage inequality in the short run if the income share of capital in the agricultural sector is relatively large. Owing to the presence of external economies, a decrease in the services sector's fixed cost increases wage inequality in the long run. A decrease in import duty on the agricultural good increases wage inequality in the short as well as the long run but its effect in the long run is stronger due to the presence of external economies in the industrial sector.     

A SURVEY ON THE OUTPUT EFFECTS OF TAX REFORMS FROM A POLICY PERSPECTIVE

This study reviews the existing evidence on the effects of tax reforms on output levels and growth over the short and long run from different strands of the literature. It develops and applies criteria to evaluate the usefulness of ex‐post estimates to predict the effects of tax reforms ex ante. Based on these criteria, we present detailed tables summarizing and comparing ex‐post estimates of the effects of tax reforms. Overall, our review suggests that at least the direction of the short‐run and long‐run growth effects can be predicted with a reasonable degree of certainty, but there is disagreement with respect to the magnitude. Our review also suggests that depending on the tax change, trade‐offs between short‐run stabilization and long‐run growth may arise and that more research on this question is needed.

Trade Liberalization and Cartel Stability

Can reduced trade barriers promote a collusive understanding about not exporting into each others domestic markets? Reduced trade costs increase the short‐run gains from starting exporting, but can also make the long‐run punishment of such a strategy harsher. If collusion on prices is supported by a trigger strategy, a reduction in trade costs weakens competition in the sense that collusion is easier to sustain. In a corresponding model with collusion on quantities, this conclusion is reversed. The authors also discuss how results change if grim trigger strategies are replaced by stick‐and‐carrot punishments.     

Rigid labour markets with trade and capital mobility: theory and evidence

Abstract We develop a multi‐country model with imperfect labour markets to study the effect of labour market frictions on bilateral trade flows. We use a framework that allows for goods trade and capital mobility and show that labour market imperfections exert opposite effects in the absence of capital mobility (the short run) and its presence (the long run), respectively. In the short run, a higher degree of labour market rigidity decreases the value of total trade, but increases the share of intra‐industry trade for a country that is larger than its trading partner. The reverse effects are observed when capital is allowed to cross country borders. Using data on unemployment and income distribution for 23 OECD countries, we compute the central parameter in our theoretical model that describes the degree of labour market rigidity. We use this new empirical concept to provide evidence for our theoretical findings by means of reduced‐form regressions as well as simulation results of a calibrated general equilibrium model.     

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.
