Nonlinear effects of exchange rate changes on the South African bilateral trade balance

In testing for the J-curve, previous studies have shown that the trade balance model is better fitted using cointegration and error correction mechanisms. These mechanisms are able to incorporate the short-term deterioration and the long-term improvement of the trade balance – the definition of the J-curve. However, the drawback of the established cointegration and error correction frameworks is that they assume symmetry in the equilibrium adjustment process. Incidentally, studies which have used the linear frameworks have found little support for the J-curve. Since the adjustment process could be nonlinear, a fresh investigation of the J-curve using nonlinear approaches could provide competing evidence. This paper retested the J-curve by using quarterly data for South Africa and her key trade partners (China, Germany, India, Japan, the UK and the USA) and found the linear specification to support the J-curve phenomenon in only two cases (India and the USA) under relaxed conditions. In contrast, the nonlinear specification supported the J-curve phenomenon in all cases at no cost of serial correlation and functional misspecification. We also found the real exchange rate changes to have significant nonlinear effects on the South African trade balance.     

Pharmaceutical cost‐sharing systems and savings for healthcare systems from parallel trade

This paper studies the consequences of parallel trade in a two‐country model. It compares a coinsurance scheme (consumers pay a percentage of the drug price) and an indemnity insurance scheme (reimbursement is independent of the drug price) with respect to changes in copayments and public health expenditure. In the destination country, copayments for patients decrease to a larger extent under indemnity insurance, whereas reductions in public health expenditure occur only under coinsurance. In the source country, copayments increase less under coinsurance, whereas health expenditure is reduced more under indemnity insurance. In both countries, total expenditure under parallel trade is lower.     

Investigating exchange rate shocks on agricultural trade balance: The case of Tunisia

The paper studies the impact of changes in Tunisia's exchange rate on the net external position of the agricultural sector. It shows that substitutability on production and consumption among domestically produced goods leads to an ambiguous impact for reasons that go beyond the Marshall-Lerner condition. Using cointegration techniques to disentangle the long and short-run impact of changes in the exchange rate on the net agricultural trade balance, we find that the depreciation of the domestic currency leads to a deterioration of the net external position of Tunisia's agricultural sector in the long-run.     

Determinants of China's bilateral trade balance in global value chains

This paper identifies the determinants of China's bilateral trade balance using a new measure based on international input–output data, the so-called ‘trade in value-added’ (TiVA), which can prevent double counting in the estimation of bilateral trade balance. Our results show that using a measure based on gross exports, rather than TiVA, causes relatively large overestimation of the impact of the RMB exchange rate on China's bilateral trade balance. This overestimation is mainly because that the increasing production of exports may require increasing intermediate imports as a consequence of international fragmentation of production in global value chains. In addition, our results also show that the impact of FDI inflows on China's bilateral trade balances depends on the position and role of China and its trading partners in GVCs.     

The exchange regime and trade balance in Turkey

Over the last 15 years, high trade deficits have become a source of external vulnerability for the relatively stabilized Turkish economy. This corresponds to the period where authorities have been following a floating exchange rate regime. Thus, this study aims to empirically show whether the adopted exchange rate regime has an impact on the trade balance for the period of 1987 Q1 to 2015 Q2. Estimation results indicate that there is a long-run relationship between the real effective exchange rate and trade balance under both fixed and floating regimes in Turkey, but there is no evidence for the J-curve hypothesis.     

Foreign exchange rate and trade balance dynamics in East African countries

This study investigates the effects of real exchange rate on trade balance in East African countries. In contrast to past studies that have often focused on one country in the region and adopted traditional empirical methods that are subject to shortcomings, the present study employed the ARDL procedure and investigated the issue in 10 East African countries. The main results are as follows. First, real exchange depreciation significantly improves trade balance for four countries in individual country estimations, as well as in panel estimation. Second, the elasticity of trade balance with respect to real exchange rate is inelastic. Elasticity slightly increases after exchange rate liberalization but remains inelastic. Third, significant short-run fall was not found for trade balance, which suggests lack of evidence for J-curve relationship     

Formation of interdependent regional trade agreements and production networks

Production networks (PNs) can be defined as a determinant of trade partnership. Deepening PNs may generate positive welfare effects and lead to a proliferation in the formation of interdependent regional trade agreements (RTAs). This paper theoretically develops the link between PNs and the formation of RTAs and empirically investigates the link by applying a qualitative choice model estimation methodology (probit) with panel data that covers bilateral country‐pairs among 147 countries between 2000 and 2010. We find that the RTA formation has been strongly driven by deepening PNs between members as well as with third countries. We also find that production network‐driven RTA interdependence is member specific.     

Asymmetric cointegration with threshold adjustment model of exchange rates and the trade balance in Turkey

This paper aims to investigate the long-run equilibrium relationship between the trade balance and exchange rates in Turkey using the asymmetric error correction model with threshold cointegration. The results provide new evidence for the asymmetric long-run relationship between the trade balance and exchange rates. Besides, deviations from the long-run equilibrium due to a relative increase in real exchange rates have a lower speed of adjustment in comparison to the deviations caused by a relative decrease in real exchange rates.     

Crude oil prices and the balance of trade: Asymmetric evidence from selected OPEC member countries

The contribution of this article is to assess whether the effects of crude oil price fluctuations on the trade balance are symmetric or asymmetric in the context of an individual oil-exporting country, specifically four OPEC member countries – Iran, Nigeria, Saudi Arabia, and Venezuela. To examine this subject thoroughly, we use three different measures of trade balances such as oil trade balance, non-oil trade balance, and total trade balance, and examine whether oil prices are asymmetrically passed on to the trade balances for those OPEC countries in the long- and short-run. After implementation of the nonlinear autoregressive distributed lag (ARDL) model, we find that changes in oil prices indeed have asymmetric effects on the oil trade balance for all four OPEC countries in the long-run, though not in the short-run. In the case of the non-oil and total trade balance, however, the asymmetry of oil price changes is not detected in both the long- and short-run.     

Asymmetric effects of oil price changes on the balance of trade: Evidence from selected African countries

The main new contribution of this study was to delve into the asymmetric impacts of changes in oil prices on the trade balance in the framework of six major African economies. To tackle this topic carefully, we employ three measures of external balances—oil, non‐oil and total trade balances, and assess the asymmetric response of the external balances of those six economies to oil price changes in the short and long run. Like most previous studies, we first assume the impacts of oil price fluctuations to be symmetric and employ the linear autoregressive distributed lag (ARDL) method to explore the topic. We then separate oil price hikes from oil price plunges and implement the non‐linear ARDL method to reveal that the price of crude oil has a vital role to play in the trade balances for those six African economies. Further, there is evidence of significant asymmetric impacts of oil prices typically on the oil trade balance of Africa's top oil producing countries. For the non‐oil and total trade balances, in contrast, there is little evidence of the asymmetry of oil price changes.     

Facilitating international production networks: The role of trade logistics

Networked trade in parts and components is more sensitive to the importer's logistics performance than is final goods trade. The difference between the two trade semi-elasticities is over 45%, which is quantitatively important. We also find that logistics performance is particularly important for trade among developing countries in the Asia-Pacific region, which is where the emergence of production networks has been most pronounced. Logistics performance is also more important for South–South trade than for South–North trade. Our results suggest that developing country policymakers can support the development of international production networks by improving trade logistics performance.     

The nature of trade,global production fragmentation and inflationary dynamics: Cross-country evidence

This study investigates under which circumstances trade has impact on inflation dynamics by examining the independent effects of trade intensity, intra-industry trade and trade on value added. Trade in goods is decomposed into consumption (final) goods and intermediate inputs to deepen the assessment of the role of the globalisation of production activities on inflation dynamics. Open-economy new Keynesian Phillips curve (NKPC) analyses suggest that inflation is sensitive to domestic factors and that the relevance of external factors changes with respect to the nature of trade, country groups and time. Vertical intra-industry trade in intermediate inputs and value-added trade play important role, whereas final goods trade has no statistically significant effect on inflation dynamics.     

中日贸易与人民币汇率:实证分析

中日贸易与人民币汇率问题,其汇率变动对贸易收支的影响是值得怀疑的。在两变量模型中,1998～2003年月度数据计量表明,中日贸易与人民币汇率之间没有长期稳定的协整关系。并且,依据中日两国月度统计数据计量的结论是相一致的。在多变量模型中计量证实,日本对华贸易收支取决于日本总产出、日本进口关税、人民币对日元实际汇率,以及中国总产出等宏观经济变量,仅仅人民币对日元实际升值,只会对日本对华贸易收支产生不利的影响。政策建议是,中日两国应该采取贸易合作政策,这样中日双边贸易收支都将会得到改善。     

Global production sharing and trade in the services of factors

This article develops an approach to measuring the factor content of trade when intermediate inputs are traded, and techniques differ for reasons such as factor price differences. An empirical section documents the importance of intermediates and shows that they mitigate cross-country differences in the factor content of finished goods. The performance of recent models of factor service trade is also evaluated. Existing approaches impute the factor content of imported intermediates with domestic techniques and tend to overstate how well those models perform. The framework developed here can help reconcile general-equilibrium trade models with actual patterns of trade.     

A Note on Impacts of International Trade on Economic Growth and Inflation

Results of this study indicate that short- and long-term effects of international trade on inflation, GDP, and inflation-adjusted GDP growth vary over periods with fixed or freely floating exchange rates or a big accumulated trade deficit. Causalities between trade and other macroeconomic variables are also different in different periods.

This study does not find supportive evidence that “phantom GDP gains” may significantly change impacts of imports on productivity, CPI, and inflation-adjusted GDP and causalities between imports and other macroeconomic variables, although a structural break is found in the relationship between imports and GDP at the beginning of 2003.     

Adjustability in production and dynamic effects of domestic competition policy

Abstract

This study explores the effect on trade balance of suppressing competition in the domestic non-tradable sector through the interaction between the short-run adjustment and the long-run adjustment in production process. Constructing a model that can capture a more short-run aspect than Yano (2001 Yano, M. 2001. Trade imbalance and domestic market competition policy. International Economic Review, 42: 729–750.  [Google Scholar]), this study demonstrates that the effect depends on the factor intensity ranking between the tradable sector and the non-tradable sector. In this model, a change in the price of the tradable good at time 0 plays an important role to explain this result.     

External adjustment in oil exporters: The role of fiscal policy and the exchange rate

After the decline in oil prices, many oil exporters face the need to improve their external balances. Special characteristics of oil exporters make the exchange rate an ineffective instrument for this purpose and give fiscal policy a sizeable role. These conclusions are supported by regression analysis of the determinants of the current account balance and of the trade balance. The results show little or no relationship with the exchange rate and, especially for the less diversified oil exporters, a strong relationship with the fiscal balance or government spending.     

The macroeconomics of commercial policy and the trade balance: A policy perspective

Given the continuing growth of foreign direct investment (FDI) in the United States, there is a growing interest in examining its impact on the rate of economic growth. The immense literature on economic growth in the United States is composed of studies that concentrate on measuring the domestic variables that affect U.S. economic growth. However, the impact of foreign direct investment on the economic growth of the United States has not received the attention that is deserves. The purpose of this study is: (1) to examine the determinants of economic growth in the United States over time, and (2) to see if there is any time-series support for the FDI-led growth hypothesis in the United States. To achieve these goals the study uses a model that is based on the postulates of de Mello. Employing a 40-year period of annual data, the model is estimated by using the Beach Mackinnon technique which corrects for autocorrelation. The estimation results suggest the following conclusions: 1. The major determinants of economic growth in the United States are total factor productivity growth, domestic investment growth, and foreign direct investment growth. 2. Causal relationships between foreign direct investment growth and economic growth is uni-directional, running from foreign direct investment to economic growth. 3. Causal relationships between foreign direct investment growth and total factor productivity growth is uni-directional, running from foreign direct investment to total factor productivity. These findings suggest that foreign direct investment growth has a significant impact on the United States economic growth. Additionally, foreign direct investment has a significant impact on total factor productivity in the United States, further contributing to the United States’ economic growth. This calls on the U.S. policy makers to devise policies that are conducive to increasing the amount of foreign direct investment in this country.     

Effect of exchange rate volatility on industry trade flows between Malaysia and China

This paper investigates the impact of ringgit/yuan volatility on Malaysian trade with her largest trading partner, China. The short- and long-run impacts are estimated using bounds testing approach to cointegration analysis and disaggregated bilateral trade data by industry over the period of 1985–2010. Specifically, we considered a total of 151 importing and 24 exporting industries in Malaysia that traded with China. Our finding indicates that cointegration existed in 94 Malaysian import industry models and 16 Malaysian export industry models. Among these cases, exchange rate volatility has short-run effects on majority of the models. However, the short-run effects shift into the long-run effects in 46 out of 69 industries in import models and 5 out of 10 industries in export models. Results indicate that the exchange rate uncertainty has positive effects on majority of these industries.     

Effects of wars and boycotts on international trade: Evidence from the late Ottoman Empire

Abstract

Between 1830 and 1913, the Ottoman Empire was involved in destructive wars with its trading partners. Boycotts were organized against Bulgaria and Austria-Hungary. The effects of wars and boycotts are a topic of debate among historians. This article examines whether wars and boycotts were associated with how the Ottoman Empire traded with its trading partners from 1830 to 1913. The findings indicate a decrease in trade with its adversaries during the Russo-Turkish War of 1877–78, the Crimean War, and the Balkan Wars. In addition, there was a statistically significant reduction in trade with Austria-Hungary due to the boycott.
