What Caused the Korean Currency Crisis in 1997?*: Weak Fundamentals or Self‐fulfilling Expectations*

The present paper investigates which factor is primarily responsible for the sharp depreciation of the Korean won against the US dollar in 1997, using a bivariate vector autoregressive model of real and nominal exchange rates. In the present study, we directly identify the relative importance of fundamental and non‐fundamental factors from the raw data series on exchange rates. This approach is different from most previous studies on the Korean currency crisis, which use proxy variables to represent the two factors. The empirical results show that the collapse of the Korean currency in 1997 appears to be mostly a result of the weakened macroeconomic fundamentals of the economy with, to a limited extent, some non‐fundamental factors.     

Target Zones and Realignment Risk: An Integrated Approach

In this paper, it is shown that inflation differentials and trade deficits were significant determinants for exchange rate movements in the European monetary system. Since the target zone prevents EMS exchange rates from adjusting gradually to changing economic conditions, a standard regression model cannot detect this influence however. Therefore, a new econometric model is introduced, in which deteriorating competitiveness increases the probability of large depreciations and high volatility. These depreciations can be due to large devaluations or to panic reactions of the market due to expected devaluations. It is shown that the out-of-sample predictions of the model outperform the random walk, and that large arbitrage gains can be made in the foreign exchange market if our model predictions are used.     

The Behavior of the Real Exchange Rate Under Fixed and Floating Exchange Rate Regimes

This article investigates the behavior of real exchange rates under fixed and flexible exchange rates. Using data from both the Bretton Woods and the modern floating periods, we decompose real exchange rate movements into components attributable to supply shocks, real demand shocks, monetary shocks, capital flows shocks, and real oil price shocks. Empirical results show that real demand shocks are an important source of real exchange rate movements under both fixed and flexible rates, while monetary shocks are negligible. Supply and oil price shocks seem to be more important under Bretton Woods, while capital flows shocks seem to explain a relatively higher proportion of real exchange rate movements under the modern floating period.     

How would Capital Account Liberalization Affect China＇s Capital Flows and the Renminbi Real Exchange Rates？

In this paper we study the determinants of gross capital flows, project the size of China's international investment position in 2020, and analyze the implications for the renminbi real exchange rate if China liberalizes the capital account. We assume in this exercise that the renminbi will have largely achieved capital account convertibility by the end of the current decade, a timetable consistent with recent proposals by the People's Bank of China. Our analysis shows that if the capital account were liberalized, China's gross international investment position would grow significantly, and inflows and outflows would become much more balanced. The private sector would turn its net liability position into a balanced position, and the official sector would reduce its net asset position significantly, relative to the country's GDP. Because of the increasing importance of private sector foreign claims and the decreasing importance of official foreign reserves, China would be able to earn higher net investment income from abroad. Overall, China would continue to be a net creditor, with the net foreign asset position as a share of GDP remaining largely stable through this decade. These findings suggest that the renminbi real exchange rate would not be particularly sensitive to capital account liberalization as capital flows are expected to be two‐sided. The renminbi real exchange rate would likely be on a path of moderate appreciation as China is expected to maintain a sizeable growth differential with its trading partners.     

Fiscal announcements and real exchange rate dynamics

This paper examines the dynamic impact of anticipated government spending on real exchange rates in a general-equilibrium framework. I show that an increase in government spending causes persistent movements in real exchange rates, and that the time profile of real exchange rates differs with patterns of government spending. Hence, one of the explanations for the misalignment and excess volatility of real exchange rates during the flexible exchange rate system may be volatile changes in government spending.     

Mean‐reverting and Asymmetric Volatility Switching Properties of Stock Price Index,Exchange Rate and Foreign Capital in Taiwan*

The main purpose of the present study is to explore the relationships among stock price index, exchange rate and foreign capital in Taiwan and to detect whether the mean‐reverting and asymmetric volatility switching properties exist in these markets. The multivariate asymmetric nonlinear smooth transition generalized autoregressive conditional heteroskedastic in mean model is used in this study. The empirical results indicate that overbuy and oversell rates of foreign capital influence the movements of the stock price index and the exchange rate. All three conditional means exhibit asymmetric mean‐reverting behavior, with negative returns reverting quicker than positive returns in terms of both speed and magnitude. The empirical results also demonstrate that the conditional heteroskedasticities of these markets are asymmetric, generating different volatility persistence under a prior positive and negative return shock.     

The Complex Dynamics of Real Exchange Rates with Countercyclical Balance of Trade

We extend Dornbusch's (1973) model to determine whether the countercyclical trade balance which is often observed in real business cycle studies can be rationalized and show that the sum of export and import elasticities being less than one is responsible for the complex fluctuation of exchange rates within this exogenous-shock-free framework.     

CURRENCY BOARD ARRANGEMENTS AS A SUPER‐FIXED ALTERNATIVE IN THE CHOICE OF EXCHANGE RATE REGIME1

Currency board arrangements (CBAs) are currently widely proposed as a super‐fixed exchange rate solution to exchange rate volatility. This paper researches the nature, operation, benefits and disadvantages of CBAs. Benefits comprise improved policy credibility, lower inflation and interest rate levels, increased economic growth, increased foreign capital flows, and sharply reduced currency speculation. These are compared with the shortcomings of CBAs, such as the absence of a lender of last resort, real exchange rate misalignments and their consequences for the economy. The paper identifies the type of country that would be the most likely candidate to benefit from a CBA.     

China＇s Import-exchange Rate Linkage： Evidence from the China-bound Exports of Japan and Korea

This paper examines how the China-bound exports of Japan and Korea are related to exchange rates, motivated by the fact that processing trade makes up a large proportion of China＇s trade, and that Japan and Korea are the leading source countries for processing imports. Because processing imports are inputs for exports, the link between such imports and China＇s exchange rates are ambiguous. We estimate export functions that include China＇s RMB real effective exchauge rates （REER） along with bilateral real exchange rates （B RER） using Johausen ＇s cointegration method aud find that the RMB REER significantly affects Japanese and Korean exports to China, even more so than BRER in most cases examined. These two exchange rates appear in the export equations with opposite signs. Subsequently, we use the estimated model to illustrate the importance of accounting for a concurrent change in B RER when analyzing the effects of a hypothetical RMB revaluation on China＇s trade balances despite the apparently weak imports-B RER linkage.     

Business Cycles and FDI: Evidence from German Sectoral Data

Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level data set on the foreign activities of German firms to test whether foreign activities are affected by business cycle developments. We aggregate the data by the sector of the reporting firm, the sector of the foreign affiliate, and the host country. Data are annual and cover the period 1989–2002. We find that German outward FDI increases in response to positive cyclical developments abroad and in response to a real depreciation of the domestic currency. JEL no. E3, F23     

Real Exchange Rates and Fundamentals: Evidence from 15 OECD Countries

In an extended Balassa–Samuelson model, long-run real exchange rates are determined by relative productivity and terms of trade. We present evidence of systematic long-run relationships between these fundamental variables and real exchange rates in a data set covering 15 OECD countries from 1960 to 1996. High relative productivity is associated with real exchange rate appreciations in most cases. There is less support for the hypothesis that the terms of trade affect equilibrium real exchange rates.     

BASKET PEGS AND EXCHANGE RATE REGIME CHANGE: AUSTRALIA AND NEW ZEALAND IN THE MID‐SEVENTIES*

The adoption of a basket peg by China in July 2005 raised interest in this form of exchange rate regime. This paper explores the emergence of the basket peg in the early 1970s, using New Zealand and Australia as case studies to examine why it was adopted, how it operated, and their policy‐makers' use of it to influence various goals. We highlight the complexity of regime choice following the collapse of Bretton Woods. For Australia and New Zealand, the basket peg was a plausible (although interim) solution when they were reluctant either to peg to a single currency or float.     

Intraday effects of macroeconomic shocks on the US Dollar–Euro exchange rates

This paper characterizes the intriguing features of high frequency 15-min Dollar–Euro foreign exchange returns data. The FIGARCH model is found to be the preferred specification for the long memory volatility process in the high frequency returns. This paper then examines how macroeconomic shocks affect the high frequency Dollar–Euro returns on an intraday basis. Quantifying the intraday effects of the shocks on the high frequency returns by using a linearly distributed lag dummy variable, this paper finds that the effects on the high frequency returns are generally statistically significant and that they appear to be asymmetric depending on the regions and the signs of the shocks and to be persistent for several lags even within a day. However, the macroeconomic shocks are found not to affect the long memory property in the high frequency returns implying that the linear dummy variable model may not be enough to explain the long memory property.     

Japan＇s Bubble,the USA＇s Bubble and China＇s Bubble

This paper compares the three recent episodes of boom and bust cycles in asset prices: Japan in the late 1980s to the 1990s; the USA since the mid‐1990s; and China during the past decade. Although we have not yet seen a collapse of Chinese property prices, their increases so far are comparable to those in the other two episodes and a careful comparative study is warranted. The present paper first examines the behavior of asset prices, of property prices in particular, in the three cases, and highlights some similarities. The paper emphasizes the role played by extremely easy monetary policy in generating bubble‐like asset price behavior in the three cases. The reason for easy monetary policies is investigated. In the US case, the monetary authority was concerned about the risk of deflation in the early to mid‐2000s. The experiences of Japan and China are quite similar in that the monetary authorities of both countries were seriously concerned about the possible deflationary effects of exchange rate appreciation on the economy. The implications of such a finding for the future of Chinese macroeconomic policy are discussed.     

Deviations from long-run equilibria and probabilities of devaluations: An empirical analysis of Danish realignments

Deviations from Long-Run Equilibria and Probabilities of Devaluations — An Empirical Analysis of Danish Realignments. — The probabilities of realignments between the Danish krone and the D-mark are investigated for the 1979–1995 period. Two multivariate systems are estimated. In the I (1) systems, the deviations from the cointegration relations are used as explanatory variables when determining the probabilities of exchange rate changes. It is found that real imbalances in the economy have to a large extent determined the probabilities of central parity changes. Furthermore, the probabilities of central parity changes have been significantly lower after 1983.     

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.     

Simple credibility tests of the ERM bands for the pound sterling and the Italian lira

This article presents evidence that the European Monetary System (EMS) bands for the Italian lira and the pound sterling were not credible for most of the period 1990–1992, and especially during the week prior to their withdrawal from the EMS system. Using a simple test, developed by Svensson, domestic interest rates for both Italy and the United Kingdom have been found to be mostly outside the rate-of-return bands implied by the official arrangements of the EMS target zone system. Furthermore, comparing implied forward rates for various maturities with the official EMS bands of both currencies, we again found that the followed monetary policies in both countries were not in general consistent with those needed to maintain an orderly functioning of the (EMS) system. The Svensson test can further be used as an indicator of potential speculative attacks on an EMS currency, and, in turn, as a signal of an emerging need to adjust the corresponding country's monetary policy.
