Exchange Rate Economics

The paper summarizes the current theory of how a floating exchange rate is determined, dividing the subject into what determines the steady state and what determines the transition to steady state. The inadequacies of this model are examined, and an alternative “behavioral” model, which recognizes that the foreign exchange market is populated by both fundamentalists and chartists is presented. It is argued that the main importance of understanding the foreign exchange market for development strategy is to permit a correct appraisal of the dangers of Dutch disease. Empirically it seems that from the standpoint of promoting development it is preferable to have a mildly undervalued rate. The paper concludes by examining implications for exchange rate regimes.

Labour Use and its Adjustment in Indian Manufacturing Industries

Abstract

This study provides an empirical investigation of the adjustment process of labour in Indian manufacturing industries, which evolved through structural transformation in the era of globalization. The analysis is based on a dynamic model applied to a panel of 22 two-digit manufacturing industries for the time period of 22 years covering 1980/1981 to 2001/2002. It is assumed that as competition increases industries adjust their employment to a desired level which is both industry and time specific. The results indicate that the manufacturing sector has shown a considerable dynamism in adjusting its workforce. The long-run labour demand responds greatest to the output, followed by capital and least by wages. It is observed that Indian manufacturing is not inefficient in labour use as modest speed of adjustment has led employment size closer to the optimal level.     

Do Financial Market Variables Show Indicator Properties Relative to Exchange Rate Returns?

This paper assesses the contemporaneous indicator properties of financial market variables relative to movements in six major developed country currency pairs. As indicator variables changes in various relative asset prices, short-term portfolio flows and currency options data are used. We find that changes in equity index differentials, short-term speculative flows and risk reversals on currency options prices exhibit consistent indicator properties for several currency pairs. Since 1999, changes in short-term interest rate differentials have gained importance as indicators. The best indicator variables explain over 50 per cent of monthly returns of the USD/EUR and GBP/USD exchange rates and over 60 per cent of the appreciation and depreciation episodes of the USD/EUR and JPY/EUR currency pairs.

Central Bank Intervention and Heterogeneous Exchange Rate Expectations: Evidence from the Daily DEM/US-Dollar Exchange Rate

In this paper we propose a generalisation of the noise trader transmission mechanism to examine the impact of central bank intervention on exchange rates. Within a heterogeneous expectation exchange rate model intervention operations are supposed to provide support for chartist or fundamentalist forecasts, which forces portfolio managers to adjust their foreign currency positions. The empirical examination of the hypothesis is done by applying a Markov regime-switching approach to daily DEM/US-dollar exchange rates and intervention data of the Deutsche Bundesbank and the Federal Reserve from 1979 to 1992. It is shown that chartists profits rose whenever these central banks intervened on the foreign exchange market. This is not true for those who follow a fundamentalist approach.JEL Classification Numbers: F31, C32, E58, G15     

Mozambique Metical Exchange Rate Dynamics: Evidence of Fractional Co‐Integration in the USA and South African Rates

This paper studies the exchange rate dynamics of the Mozambique metical with respect to the US dollar and the South African rand. However, instead of using standard I(0)/I(1) techniques, we use long memory and fractionally integrated and co‐integrated models. Our results indicate that the two exchange rates are highly persistent, with orders of integration equal to or above 1. They also seem to be co‐integrated, with an order of integration close to albeit above 0 but with an AR coefficient very close to 1. Thus, although the two series seem to be fractionally co‐integrated, shocks in the long‐run relationship between the two variables are persistent and take a long time to disappear.     

Exchange Rate Regime and Demand for Reserves: Evidence from Kenya,Mexico and Philippines

This paper empirically investigates the demand for international reserves (and foreign exchange reserves) during fixed and floating exchange rates periods in three developing countries: Kenya, Mexico and Philippines. Based on theoretical models, three factors are identified as important for the demand of international reserves and foreign reserves: average propensity to import, volume of imports and variability of reserves. The paper employs the cointegration methodology and error correction method to investigate the relationships. Cointegration tests results indicate a reliable long-run stationary relationship between the international reserves (and foreign exchange reserves) and the stated explanatory variables across countries and sub-periods of fixed and clean float. The error correction results indicate causality from the explanatory variables to the reserves during both the short and long run. This is true during both the fixed and the floating periods.

Foreign Transfers and Real Exchange Rate Adjustments in a Financially Constrained Dependent Economy

This paper investigates the role of the real exchange rate in determining the effects of foreign transfers. If capital is perfectly mobile between sectors, a pure transfer has no long-run impact on the real exchange rate. A decline in the traded sector occurs because the transfer, being denominated in traded output, substitutes for exports in financing imports. While a pure transfer causes short-run real exchange appreciation, this response is temporary and negligibly small. Transfers allocated to productivity enhancement do generate permanent real exchange rate adjustments in response to the sectoral reallocation of productive factors. The analysis, which employs extensive numerical simulations, emphasizes the tradeoffs between real exchange adjustments, long-run capital accumulation, and economic welfare, associated with alternative forms of transfers.

Pitfalls in Measuring Exchange Rate Misalignment

We evaluate whether the Renminbi (RMB) is misaligned, relying upon conventional statistical methods of inference. A framework built around the relationship between relative price and relative output levels is used. We find that, once sampling uncertainty and serial correlation are accounted for, there is little statistical evidence that the RMB is undervalued, even though the usual regression point estimates indicate substantial misalignment. The result is robust to various choices of country samples and sample periods, as well as to the inclusion of control variables. We then update the results using the latest vintage of the data to demonstrate how fragile the results are. We find that whatever misalignment we detected in our previous work disappears in this data set.

Exchange Rate Cycles and Canada/US Manufacturing Prices

The paper examines the industry characteristics that are related to the shifts in competitiveness, measured as the relative common-currency price ratios between Canadian and US manufacturing prices. We find that relative input costs and relative productivity growth are the two most important factors influencing changes in relative Canada/US prices. Competitive pressures emanating from trade are important determinants of the extent to which relative productivity differences are passed through to cross-country relative prices. We also find that the magnitude of domestic market competition and export intensity affects the short-run relative price shifts over the cycle of exchange rate. JEL no. E30, F31, L60     

Impact of Macroeconomic Announcements on Foreign Exchange Volatility: Evidence from South Africa

This study focuses on scheduled macroeconomic news announcements and evaluates their impact on the volatility of the South African rand (ZAR) and US dollar (USD) exchange rate using high frequency data. The following asymmetries are studied: news items by geographical location, no‐news vs. surprise news announcements and positive vs. negative news announcements. We make the following findings in our empirical study: (i) After the release of a news announcement, the level of foreign exchange volatility rises. This is independent of whether the news item surprised the market or not. (ii) Both South African and US news items significantly impact USD/ZAR volatility, suggesting that the news items are being used to formulate investor expectations regarding the future prospects of the currency pair. (iii) Negative news appears to have a greater impact on exchange rate volatility relative to positive news. This result is also state dependent, as investors tend to behave differently to news depending on the economic climate at that point in time. Investor cognitive biases give rise to the asymmetric news effects on exchange rate volatility. Finally, investors do not always act in rational manner, especially when faced with multiple news items that are contradictory to each other.     

我国出口汇率传递的非对称性:来自中日贸易的证据

文章扩展了Yang（2007）的厂商定价模型,对汇率传递非对称性、特点和成立条件进行理论分析,发现对称传递需要满足严格的条件,而现实中更常见的是非对称汇率传递。在一定条件下,商品需求弹性越大,越可能呈现出口国货币贬值传递率高而升值传递率低的特点。利用2000年1月至2011年12月我国出口日本的966种商品价格数据,发现汇率波动向价格传递具有非对称性：（1）人民币升值时,日元价格上涨较少;而贬值时,价格下降较多。我国出口商品的需求弹性较大,在日本市场上面对的是一个强竞争结构。（2）若月度升值超过一定幅度（测算约为2.43%）,传递率又会有所上升,说明尽管日元价格易跌难涨,但在升值导致成本上涨较多、明显挤压利润时,厂商不得不适当提高日元售价。采用2000年至2018年9月日本从中国进口单位价值指数进行稳健性检验,得出类似结论。现阶段稳定的人民币名义汇率对我国出口企业是更为有利的。     

Fixed Exchange Rates and Disinflation in Emerging Markets: How Large Is the Effect?

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.

Exchange Rate Forecasting: Results from a Threshold Autoregressive Model

Structural models of exchange rate determination rarely forecast the exchange rate more accurately than a naive random walk model. Recent innovations in exchange rate modeling indicate that changes in the exchange rate may follow a self-exciting threshold autoregressive model (SETAR). We estimate a SETAR model for various monthly US dollar exchange rates and generate forecasts for the estimated models. We find: (1) nonlinearities in the data not uncovered by the standard nonlinearity tests and (2) that the SETAR model produces better forecasts than the naive random walk model.     

金融发展与中间品离岸水平:基于制造业外部融资依赖度的实证分析

在国际生产网络不断扩张与深化的背景下,一国较高的金融发展水平会降低成本,提高本土产品的竞争力,进而影响企业的国际生产网络布局。文章在要素禀赋理论的框架下,采用美国制造业数据,考察贸易伙伴国金融发展对中间品离岸水平的影响,并进一步引入引力因素进行实证检验,结果表明,贸易伙伴国金融发展水平的提高会促进美国各产业离岸水平的提升,这种促进作用在外部融资依赖度高的产业上更为显著,即企业会将更多的生产环节布局在金融发展水平较高的国家。在考虑了不同计量技术、指标并分样本后上述结论依然稳健。     

Stock market uncertainty and uncovered equity parity deviation: Evidence from Asia

Recently, many empirical studies document that a country's stock market performance relative to the US and its local currency units per US dollar tend to move in opposite direction over the short run, also known as the uncovered equity parity (UEP) condition. However, those studies have applied only to advanced economies to date. This study conducted the same tests to a sample of 18 Asian economies. To one's surprise, we found that the UEP condition reverses its sign among Asian currencies. In addition, measures of stock market uncertainty are suggested as a potential driving force behind this UEP reversal for Asian economies. This surprising result suggests that there might be other mechanisms behind the joint dynamics of equity and currency returns than the portfolio rebalancing caused by incomplete foreign exchange risk hedging. The reasoning is that Asian foreign exchange (FX) markets are even more subject to incomplete foreign exchange risk hedging. Thus, one should expect even stronger UEP evidence from Asian currency markets if the portfolio rebalancing mechanism was the only force at play.     

The Effect of Exchange Rate on Bilateral Trade Balance: New Evidence from Malaysia and Thailand

This paper attempts to identify the major economic factors that influence the bilateral trade balances of Malaysia and Thailand with the US and Japan. To this end, an unrestricted VAR model was estimated using quarterly frequency data from 1980: I to 1996: IV. The Johansen results indicate a stable long-run relation between trade and three macro variables: exchange rate, domestic income and foreign income. The main findings of this paper are: (i) the real effective exchange rate is an important variable in the trade balance equation and devaluation improves the trade balances of both economies in the long-run; (ii) the other important variables that determine trade balance include domestic and foreign incomes; (iii) the results indicate no J-curve effect and causal run from exchange rate to trade balance, (iv) the real effects of devaluation are distributed over a period of eight to nine quarters.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.     

The South Africa-U.S. Trade and the Real Exchange Rate: Asymmetric Evidence from 25 Industries

Previous studies that assessed the effects of exchange rate changes on the trade balance of South Africa assumed that the effects are symmetric. In this paper we violate that assumption and assess the asymmetric effects of the real rand-dollar rate on the trade balance of 25 2-digit industries that trade between South Africa and the U.S. We find short-run asymmetric effects in a total of 19 industries but short-run cumulative or impact asymmetric effects only on five industries. Short-run asymmetric effects lasted into long-run asymmetric effects on 14 industries. Further analysis revealed industries that will benefit from rand depreciation and those that will be hurt from rand appreciation.
