Real Exchange Rate Changes and the Trade Balance: The Evidence from Pakistan

This study uses quarterly data from July 1980 to June 2006 to explore the relationship between changes in real exchange rate and the trade balance of Pakistan. Applying the Auto Regressive Distributed Lag (ARDL) approach to cointegration, we examine the existence of a possible long-run relationship. We find the following: (1) a long-run relationship between the series exists, and (2) the coefficient of elasticity is negative and statistically significant, which does not support for the J-relation.

Given this, the policymakers should take a conservative approach in using currency devaluation to cure the fundamental disequilibrium in the balance of payments. It is likely that such policy may not produce the desired outcome—i.e., the trade balance may not improve.     

Real Exchange Rate Volatility on the Short- and Long-Run Trade Dynamics in Colombia

The short- and long-run implications of real exchange rate volatility on Colombian bilateral trade commodities and non-commodities with its major trade partners are analyzed from the perspectives of the Marshall-Lerner condition, a cointegration relation with other aggregate variables, and the J-curve hypothesis. Long-run equilibrium on the Colombian bilateral balance of trade with a country is more common when the trade volume is denominated in terms of one of the world's main currencies—as is the case of commodity trade and trade with a country whose national currency is one of these currencies. No evidence of the J-curve was found in any of the analyzed Colombian bilateral balances of trade. Opposite to the predictions of the J-curve hypothesis, more common are the scenarios of short-run improvements in the bilateral trade balances following a devaluation than are those with instantaneous declines. Improvements in the terms of trade are found to have a long-run deteriorating impact on the Colombian balance of trade, especially in the case of non-commodity trade. Policy makers should consider that continuous improvements in the Colombian terms of trade, as the ones recently observed, will ultimately be a detriment to the country's current balance of trade surplus.     

The impact of parallel market exchange rate volatility and oil exports on real GDP in Syria: Evidence from the ARDL approach

This paper investigates the impact of parallel market exchange rate volatility and trade on real GDP and real GDP growth in the Syrian economy over the period of 1990Q1–2010Q4. To this end, we first construct a parallel market exchange rate volatility indicator. Second, we estimate an autoregressive distributed lag (ARDL) model where we include our indicator of volatility among the main determinants of real GDP. Our findings imply that real GDP can be explained by three main variables: parallel market exchange rate, money supply, and oil exports. The long-run equilibrium reveals that parallel market exchange rate volatility has a negative impact on real GDP compared to the positive impact of money supply and oil exports. In contrast, the short-run impact of parallel market exchange rate volatility on real GDP growth is positive and very small counter to the long-run impact. Furthermore, the coefficient of the error correction term of the estimated ARDL model indicates that real GDP deviation from the equilibrium level will be corrected by about 10% after each quarter.     

Twin deficit or twin divergence? Fiscal policy, current account, and real exchange rate in the U.S.

In spite of concerns about “twin deficits” (fiscal and the current account deficits) for the United States economy, empirical evidence suggests that “twin divergence” is a more usual feature of the historical data, i.e., when fiscal accounts worsen, the current account improves and vice versa. This paper empirically studies the effects of fiscal policy (government budget deficit shocks) on the current account and the real exchange rate, during the flexible exchange rate regime period. Based on VAR (Vector Auto-Regression) models, we identified “exogenous” fiscal policy shocks after controlling for business cycle effects on fiscal balances. In contrast to the predictions of most theoretical models, the U.S. results suggest that an expansionary fiscal policy shock, or a government budget deficit shock, improve the current account and depreciate the real exchange rate. Increases in private savings and declines in investment contribute to the current account improvement while a nominal exchange rate depreciation, as opposed to a relative price level change, is mainly responsible for the real exchange rate depreciation. The “twin divergence” of fiscal balances and current account balances is also explained by the prevalence of output shocks, i.e. output shocks — more than fiscal shocks — appear to drive the co-movements of the current account and the fiscal balance.     

How do fiscal and technology shocks affect real exchange rates?: New evidence for the United States

Using vector autoregressions on U.S. time series relative to an aggregate of industrialized countries, this paper provides new evidence on the dynamic effects of government spending and technology shocks on the real exchange rate and the terms of trade. To achieve identification, we derive robust restrictions on the sign of several impulse responses from a two-country general equilibrium model. We find that both the real exchange rate and the terms of trade—whose responses are left unrestricted—depreciate in response to expansionary government spending shocks and appreciate in response to positive technology shocks.     

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.     

美元贬值对中国进出口企业的影响及对策

美元下跌之势难抑,国际外汇市场风险加剧。美元的贬值影响到以美元计价商品进口成本的提高,从而压缩了企业利润水平,容易诱发新一轮的贸易保护和贸易摩擦。人民币采取盯住美元有管理的固定汇率制度,美元贬值使人民币被动贬值。在长期实行的结售汇制定下,企业调整外汇净头寸的能力非常差,汇率波动对净头寸造成的损失是巨大的。中国应加强对未来汇率变动趋势的预测和把握,从根源上铲除被诉反倾销的隐患。     

Long-run real exchange rates in the Four Little Dragons

This paper analyses changes in the exchange rate arrangements and policy and their impact on the long-run real exchange rates of the Asian Four Little Dragons. It is found that purchasing power parity is a basic guide in formulating the exchange rate policy of the Four Little Dragons and that exchange rate regimes are very responsive to the effect of major external disturbances on prices. Thus, the exchange rate policy and arrangements are important factors in shaping the behaviour of the real exchange rates of the FLDs, which tend to return to the long-run average value. To test the null hypothesis that purchasing power parity does not hold between the Four Little Dragons and the United States, two cointegration tests, the augmented Dickey-Fuller (ADF) test and the Johansen test, are applied. As the symmetry and proportionality conditions are not supported by the data, the tests are conducted in a trivariate system. While the ADF test does not support PPP, evidence of cointegration is found by the Johansen test.     

假命题:“人民币汇率操纵”—一个基于马歇尔勒纳条件的实证

本文以后危机时代为背景,在中美人民币汇率现实争端以及学术界现有研究的基础上,从《IMF协定》关于"汇率操控"的定义出发、通过实证研究和对中美两国贸易实践的理论分析,得出美国等发达国家对中国政府"汇率操控"的指控不满足马歇尔-勒纳条件,即人民币贬值并不能带来中美贸易顺差。中美之间的贸易实践也有力地证明了美国对中国政府操纵汇率的责难缺乏事实依据和理论基础。美元主宰的国际货币体系、美元的霸权地位、美国的出口管制、美国的经济结构、消费模式等才是美国贸易逆差的最主要原因。     

Is there an optimal crawl?

This paper shows that optimal exchange rate policy can be defined in terms of either a long-run secular policy or a short-run stabilization policy. The rate of crawl which maximizes real per capita consumption is shown to often differ from the exchange rate movements produced under fixed or floating exchange rates. And the optimal program for dealing with short-run speculative capital flows will involve both discrete and gradual exchange rate changes. It is also argued that domestic monetary policy and exchange rate policy are not independent instruments.     

An Empirical Analysis of the Determinants of Interest Rates in Ghana

ABSTRACT

This paper provides an empirical analysis of the determinants of the bank lending rate in Ghana using annual time series data from 1970 to 2013. We found evidence of a long-run equilibrium relationship between the average lending rate charged by commercial banks and its determining factors. In the long run, bank lending rates in Ghana are positively influenced by nominal exchange rates and Bank of Ghana’s monetary policy rate but negatively with fiscal deficit, real GDP and inflation. We also find positive dependence of the bank lending rate on exchange rates, and the monetary policy rate both in the short and long run. Specifically, our findings reveal that the Bank of Ghana’s monetary policy rate and the exchange rate, by far, show strong contemporaneous effects on the average bank lending rate in Ghana.     

A REASSESSMENT OF AGGREGATE IMPORT DEMAND FUNCTION IN THE ASEAN-5: A Cointegration Analysis

This study aims to reinvestigate the empirical evidence on the long-run relationship of aggregate import demand behavior for the ASEAN-5 founding nations. This study adopts the import demand equation that has been developed by Xu (2002). The results of bounds test (Pesaran et al., 2001) show the volume of imports, activity variable (national cash flow), and relative price of imports are cointegrated in Malaysia and Singapore. However, no empirical evidence supports that these variables are cointegrated in Indonesia, Thailand, and the Philippines. This study provides a relevant implication specifically that devaluation strengthens the balance of trade. Following the Marshall-Lerner condition, exchange rate policies such as devaluation, can used to improve trade balance in Malaysia, Singapore, the Philippines, and Thailand, but not in Indonesia.     

The Effects of Real Exchange Rate on Trade Balance and Domestic Output: A Case of Malaysia

The main objective of this study is to determine the effects of real exchange rate changes on the real Malaysian trade balance and the domestic output during the pegged exchange rate regime, 1977:1–1998:2, using quarterly data. The cointegration results suggest that a real ringgit exchange rate depreciation improves the Malaysian balance of trade in the long run. The impulse response analysis suggests that the effects of a depreciation of ringgit on the trade balance and domestic output are quite similar. A devaluation will initially improve the trade balance and domestic output, after which the trade balance starts to deteriorate and then the recession sets in, but subsequently both the trade balance and domestic output improve.     

Markov switching GARCH models of currency turmoil in Southeast Asia

This paper analyzes exchange rate turmoil with a Markov switching GARCH model. We distinguish between two different regimes in both the conditional mean and the conditional variance: “ordinary” regime, characterized by low exchange rate changes and low volatility, and “turbulent” regime, characterized by high exchange rate devaluation and high volatility. We also allow the transition probabilities to vary over time as functions of economic and financial indicators. We find that real effective exchange rates, money supply relative to reserves, stock index returns, and bank stock index returns and volatility contain valuable information for identifying turbulent and ordinary periods.     

FOREIGN EXCHANGE RATES AND FOREIGN DIRECT INVESTMENT IN THE UNITED STATES

The hypothesis that foreign direct investment into the United States responds to variations in exchange-rate levels and to exchange-rate uncertainty is tested for the period 1976-1998. We account for nonstationarity and cointegration in the data series and use conditional measures of exchange-rate uncertainty. While a long-run relationship exists among foreign direct investment in-flows as a share of GNP, the real exchange rate, and the GARCH measure of exchange-rate volatility, we find no discernible link between the real exchange rate and inward foreign direct investment in the short run. We also conclude that foreign direct investment decreases in response to increases in exchange-rate uncertainty in the short run when we use a conditional measure of exchange-rate uncertainty.     

Workers' remittances and Dutch Disease in Bangladesh

Workers' remittance is one of the major sources of foreign exchange earnings for Bangladesh in recent years. It accounted for 12% of GDP in 2009 and has colossal socio-economic implications for the country. However, the inflows of foreign exchange earnings can exert adverse effects on the international competitiveness of an economy as postulated by the Dutch Disease theory. Using Johansen Cointegration and Vector Error Correction Model and annual data from 1971 to 2008, this paper investigates the effects of remittances on the external trade competitiveness as measured by the movements of real exchange rate of the country. The results of the study suggest that the influx of workers' remittances significantly appreciates the real exchange rate and deteriorates the external trade competitiveness of Bangladesh. While increased terms of trade indicates similar adverse effects, openness in goods and capital markets and nominal devaluation improve the trade competitiveness of the country. Therefore, greater trade openness and channelling remittances to the priority investment projects can be powerful policy devices to improve the external competitiveness and avert ‘Dutch Disease' in Bangladesh.

Current account and relative prices: Are there any cointegration relationships in the presence of structural breaks in emerging economies?

The aim of this study is to examine the long-run relationship between the current account and relative prices, such as terms of trade (TOT) and real exchange rate, for the emerging economies. These variables have been exposed to large fluctuations for more than two decades in all emerging economies; therefore, structural breaks have to be taken into account in all estimations. In this article, various methodological techniques have been used to examine this long-run relationship (with and without the structural breaks). Two important results have emerged, first; when the structural changes are excluded there is a strong evidence for long-run relationship between current account and relative prices. Second; when the structural breaks are included, variables are found to be stationary. Hence, depending on the stability of the variables, the validity of the cointegration relationship has been seriously questioned. This study illustrates that the test results proving non-stationary of the series and the presence of cointegration may be spurious if there is any possibility of instability.     

Devaluation,Innovation, and Prices

We investigate the effects of exchange rate changes on innovation by a multinational corporation. The firm enjoys a monopoly in the home market but engages in Cournot competition with a domestic firm in the foreign market. Changes in currency values affect the multinational firm’s profits in domestic currency units, and thus influence the optimal level of process innovation as well as output and prices in the two markets. We find that a devaluation of the home currency will lead the home firm to increase its output in both the home and foreign markets, and increase its spending on R&D. We also find that currency devaluation in the home market leads to lower prices in both markets.     

On exports and economic growth: the case of Italy

The export-led growth hypothesis for the Italian economy (1960-98) is tested through a VAR model with four macroeconomic variables: an index of the GDP of the rest of the world; the Italian real exchange rate; Italian real exports; and the Italian real GDP. Our results provide clear empirical support for the hypothesis. They also suggest that the Kaldorian approach is very useful in analysing short-run as well as long-run growth and fluctuations of an open economy such as Italy.
