On the exchange-rate elasticity of the demand for international reserves: Some evidence from industrial countries

Summary and Conclusion In this paper we tried to investigate the supposition that a change in exchange rate lowers the demand for international reserves. This goal was achieved by incorporating the real effective exchange rate into a standard real reserve demand equation from the literature. The model was estimated for a sample of 13 countries for which the effective exchange rate was available, using pooled quarterly data over the 1973-1985 period. The empirical results revealed that a change in exchange rate indeed reduces the demand for reserves supporting the theoretical arguments of the previous studies.     

ON THE RAND: DETERMINANTS OF THE SOUTH AFRICAN EXCHANGE RATE

This paper is an econometric investigation of the determinants of the real value of the South African rand over the period 1984‐2007. The results show a relatively good fit. As always with exchange rate equations, there is substantial weight on the lagged exchange rate, which can be attributed to a momentum component. Nevertheless, economic fundamentals are significant and important. This is especially true of an index of the real prices of South African mineral commodities, which even drives out real income as a significant determinant. An implication is that the 2003‐2006 real appreciation of the rand can be attributed to the Dutch Disease. In other respects, the rand behaves like currencies of industrialised countries with well‐developed financial markets. In particular, high South African interest rates raise international demand for the rand and lead to real appreciation, controlling also for a forward‐looking measure of expected inflation and a measure of default risk or country risk.     

Exchange Rates and Trade Balance Adjustment: A Multi-Country Empirical Analysis

This study assesses the response of the trade balance to exchange rate fluctuations across a large number of countries. Fixed-effects regressions are estimated for three country groups (industrial, developing and emerging markets) on annual data for 87 countries from 1994 to 2010. The trade balance improves significantly after a real depreciation, and to a similar degree, in the long run for all countries, but the adjustment is significantly slower for industrial countries. Emerging markets and developing countries display relatively fast adjustment. Disaggregation into exports and imports shows that the delayed adjustment in industrial countries is almost entirely on the export side. The rate of adjustment in emerging markets is slowing over time, consistent with their eventual graduation to high-income status. The ratio of trade to GDP is also highly sensitive to the real effective exchange rate, with a real depreciation of 10 % raising the trade/GDP ratio across the sample by approximately 4 %. This result, which presumably reflects movements in the prices of tradables relative to non-tradables, raises questions about the widespread use of the trade/GDP ratio as a trade policy indicator, without adjustment for real exchange rate effects.     

Exchange Rate Variability and the Macro-economy: Evidence from Developing and Developed Countries

Abstract

Using annual data, the paper studies the time-series evidence regarding the allocation of fluctuations in the exchange rate between demand components, real growth, and price inflation in a sample of developing and advanced countries. The evidence reveals patterns of interaction between the macro-economy and exchange rate variability. Across developing countries, appreciation decreases the cost of imports and price inflation, while depreciation shrinks the output supply, indicating high dependency on imported goods. The reduction in output supply correlates with higher inflation and an increase in the import value. In contrast, the evidence of the negative effect of currency appreciation on output growth is more prevalent across advanced countries, while depreciation stimulates competitiveness, resulting in higher demand for exports, investment and consumption. Across developing countries, exchange rate variability decreases trend real growth and increases trend price inflation. Across advanced countries, exchange rate variability decreases trend real growth while increasing the variability of price inflation and import growth. Minimizing variability of the exchange rate would be beneficial to sustain higher growth and reduce cyclical variability in developing and advanced countries.     

Net foreign assets and macroeconomic volatility

This study analyses the co-movements of net foreign asset accumulation, consumption, real exchange rate, and real interest rate in a cross section of countries. Our sample covers both industrial and developing economies, spanning 1981–2010 period. We find that the accumulation of net foreign assets is associated with increasing consumption and real exchange rate appreciation. In a cross section of countries, when a country increases its net foreign assets to GDP ratio by a one-standard deviation, consumption to GDP increases by 0.02% per year and real exchange rate appreciates by 2% per year. Consumption to GDP responds more positively to net foreign asset accumulation in G7 countries, +0.1 to +0.2% per year, while the response is smaller and negative in developing countries reporting a −0.02% per year. The real exchange rate appreciation, however, is about +3% per year in developing countries and only about +0.2% per year in OECD countries.     

International relocation,difference in production costs,and welfare: An analysis based on a two-country model

This paper examines whether or not the globalization of Japanese companies is a problem for the Japanese economy. To examine this, using the theoretical model, the paper examines whether the globalization of home-located tradable goods firms provides a benefit to the home country from the perspective of welfare. Specifically, since globalization is thought to have begun based on the difference in production costs of the home and the foreign country, we examine how an increase of productivity in the foreign non-tradable goods sector, which is the principal factor in the difference in production costs between the two countries, affects the welfare of the home country. We show that such an increase of productivity not only induces enterprise relocation, but also improves the welfare of the home country. In particular, the latter is demonstrated by an increase in the real flow of dividends that results from holding equities in tradable goods firms located abroad, i.e., the improvement in the income account. Hence, since the prediction of the model indicates that the globalization of firms is not a problem, it can be said that the globalization of Japanese firms is not a problem for the Japanese economy.     

Nontradable Goods and the Real Exchange Rate

How important are nontradable goods and distribution costs to explain real exchange rate dynamics? We answer this question by estimating a general equilibrium model with intermediate and final tradable and nontradable goods. We find that the estimated model can match characteristics of the data that are relevant in international macroeconomics, such as real exchange rate persistence and volatility, and the correlation between the real exchange rate and other variables. The distinction between tradable and nontradable goods is key to understand real exchange rate fluctuations, but the introduction of distribution costs is not. Nontradable sector technology shocks explain about one third of real exchange rate volatility. We also show that, in order to explain the low correlation between the ratio of relative consumption and the real exchange rates across countries, demand shocks are necessary.     

实际汇率对欧元区内出口贸易影响的实证分析

汇率是调节一国进出口贸易的重要工具,在欧元区由于使用统一的货币,这使得成员国无法通过改变汇率来调节本国的进出口贸易,而成员国的通货膨胀率的不同造成了欧元区各国的实际汇率并不相同,实证分析发现,实际汇率与区内出口贸易存在着明显的负相关,实际汇率每增加1%,区内出口就会减少2.39%。     

The impact of market regulations on intra-European real exchange rates

We study the contribution of market regulations to the dynamics of the real exchange rate within the European Union. Based on a model proposed by De Gregorio et al. (Rev Int Econ 2(3):284–305, 1994a), we show that both product market regulations in nontradable sectors and employment protection tend to raise the real exchange rate. We then carry out an econometric estimation for European countries for 1985–2006 to quantify the contributions of the pure Balassa–Samuelson effect and those of market regulations on real exchange-rate variations. Based on this evidence and on a counter-factual experiment, we conclude that the relative evolutions of product market regulations and employment protection across countries play a very significant role for real exchange-rate variations within the European Union and especially within the euro area, through their impacts on the relative price of nontradable goods.

汇率变动对工资和就业结构影响的实证分析

本文由Frenkel两部门理论模型,采用IMF提供的人民币对美元实际汇率数据,通过实证分析发现,实际汇率升值会显著减少贸易部门就业,即人民币升值使贸易部门就业人数显著减少,非贸易部门第二产业工人就业人数会增加,对第三产业工人就业影响不大,但就业工人实际工资水平都会有所提高。所以本文的结论是,人民币升值能提升中低阶层福利水平,支持人民币升值。     

Is the emergence of new sovereign wealth funds a fashion phenomenon?

The paper deals with the important financial policy issue of the decision for a country to establish a sovereign wealth fund (SWF). Using a large-scale database, we analyze the economic, political and institutional factors that should be considered in such a decision. In particular, we test if the emergence of SWFs and more specifically of a specific type of SWFs can be explained by the following factors: the excess foreign exchange reserves due to natural resources rents or persistent current account surpluses; the volatility of commodity prices; the appreciation of the real exchange rate leading to the “Dutch Disease” effect and the governance of the country. The results suggest that countries with excess foreign exchange reserves, which are dependent on a commodity and which suffer from an appreciation of the real exchange rate are more likely to create a fund. We also find that commodity-based funds tend to be established in low democratic countries. Finally, our results suggest that the factors driving SWFs creation are different depending on the origin of the funding (commodity or non-commodity) and the macroeconomic objective(s) assigned to the fund. Our results may be of interest for policymakers debating whether or not it can be optimal for the country to establish a SWF.     

Currency Misalignments in the BRIICS Countries: Fixed Vs. Floating Exchange Rates

In the present paper we attempt to investigate whether the real effective exchange rates of the BRIICS countries, namely Brazil, Russia, India, Indonesia, China and South Africa, converge or not to their equilibrium levels. Our analysis is based on the use of an external balance model as well as the implementation of recent panel cointegration techniques. Our evidence indicates the existence of a valid long-run relationship between the real effective exchange rate, the net foreign assets, the GDP differential and the real interest rate differential for each of the six countries of our sample. Furthermore, our empirical results imply that after the adoption of a free floating exchange rate regime by Brazil, Russia, India, Indonesia and South Africa and the liberalisation of the Chinese exchange rate policy that took place during the last decade, currency misalignments have been gradually reduced, leading the real effective exchange rates of the respective currencies very close to their equilibrium levels.     

人民币实际有效汇率的水平与波动性对就业的影响——基于东部地区面板数据的实证分析

自2005年汇率制度改革以来,人民币正式进入升值通道,并已经对实体经济运行产生了重要影响。本文选择中国东部11省(市)、1994～2007年的年度数据,建立面板数据模型,分析人民币实际有效汇率的水平与波动性对就业量的影响。结果发现,人民币实际有效汇率的水平与就业量显著负相关:在其它条件不变的情况下,人民币实际有效汇率指数上升1%,就业量将下降0.126%;人民币实际有效汇率的波动性对就业量仅具有轻微的负面影响。文章最后就如何减轻人民币升值对就业的负面影响提出了若干政策建议。     

Do Real Exchange Rates Follow a Nonlinear Mean Reverting Process in Developing Countries?

In an effort to fight relatively high inflation, many developing countries try to manage their nominal exchange rates through official intervention. In addition, developing countries tend to have high transportation costs, tariffs, and nontariff barriers. These factors are among the sources of generating nonlinearity in real exchange rates and hence some nonlinear adjustment toward purchasing power parity (PPP) in developing countries. In this paper, we employ monthly real effective exchange rate (REER) data of 88 developing countries and test the null of nonstationarity versus an alternative of linear stationarity by the means of a conventional unit root test and compare the results with those obtained from a new test in which the null is the same but the alternative hypothesis is nonlinear stationarity. The latter test supports the PPP theory in more developing countries compared with the former test, suggesting that nonlinear adjustment toward PPP in developing countries is an important phenomenon. Reported country characterizations indicate that reversion in REER occurs more often for high-inflation countries and for countries with high flexibility in their exchange rates.     

Currency Substitution and the Stability of the Demand for Money in East Asia

Abstract

This paper models and tests the stability of the demand for money in five East Asian countries—Indonesia, Malaysia, Philippines, Singapore, and Thailand—in the context of an open economy. The Johansen multivariate cointegration vector error correction analysis against quarterly data covering the period 1985:1–2001:4 was used. It was found that a stationary long run cointegrating relationship exists between broad money, real income, domestic interest rates, foreign interest rates corrected for exchange rate depreciation, and the expected rate of depreciation of the exchange rate. The results show that US Treasury bills rates and the foreign exchange rate vis-à-vis the US dollar play a significant role in the East Asian countries money demand relationship. This suggests that currency substitution vis-à-vis the US dollar may be an important consideration in the design and implementation of monetary policy in the East Asian countries. Furthermore, the results show that the Asian currency crises impacted the money demand functions negatively in these countries. CUSUM and CUSUMSQ stability tests show no evidence of parameter instability of the money demand functions in three of the five countries throughout the period under investigation.     

Sources of Real Exchange Rate Volatility in Africa: The Case of ECOWAS*

Abstract: This study examines the impact of (real) demand shocks, (aggregate) supply shocks, and monetary shocks on real exchange rates in 13 West African countries. We observe that the real demand shocks explain most of the fluctuations in real exchange rates in all these countries. Accordingly, policymakers should adopt a careful demand management strategy by controlling government expenditure and taxes.     

Assessing the Equilibrium Exchange Rate of the Malaysian Ringgit: A Comparison of Alternative Approaches

Drawing on the behavioral equilibrium exchange rate and the fundamental equilibrium exchange rate approaches, this paper assesses the equilibrium value of the real effective exchange rate of the Malaysian ringgit over the past 25 years. For 2005, when the Malaysian authorities exited from the peg with the US dollar, both models determine a slight undervaluation of the currency. Openness and real GDP per capita have been the main drivers of real exchange rate movements in the past, although non-tradable productivity, government consumption, and net foreign assets have also had a sizable impact. The paper also highlights the limitations of applying the two approaches in the context of emerging countries.     

ESTIMATING EXCHANGE RATE AND BILATERAL TRADE BALANCE RELATIONSHIPS: THE EXPERIENCE OF SUB-SAHARAN AFRICAN COUNTRIES

This paper examines the effects of exchange rate changes on the bilateral trade balance of ten African countries vis‐à‐vis the US using annual data over period 1977‐2002. Both the Johansen and panel cointegration tests find cointegration among the series. The country FMOLS results show that real exchange rate depreciation improves the trade balance in six of ten countries in contrast to Tanzania in which it worsens the trade balance, with no effect found in Ghana, Morocco and Senegal. Foreign real income improves the trade balance in two countries but worsens it in another three. Finally, domestic real income negatively affects the trade balance in four countries but improves it in another three. The three‐panel coefficients are correctly signed and significant at the 1% level.     

国际收支视角下人民币汇率形成机制改革探讨

我国国际收支持续双顺差和外汇储备大幅增长导致了人民币升值压力的形成。目前我国已实行以市场供求为基础的有管理的浮动汇率制,且已实现了人民币经常项目下的可兑换,因而外汇市场供求和国际收支状况对人民币汇率的影响逐步加大。本文基于外汇供求模型构建了我国国际收支影响人民币汇率形成的模型并进行了实证分析,结果显示出口、外资流入和外汇储备变动对汇率的影响比较显著。最后基于上述分析对如何完善人民币汇率形成机制提出了政策建议。
