Divergence indicators and the volatility smoothness in semi-fixed exchange rate regimes

Divergence Indicators and the Volatility Smoothness in Semi-Fixed Exchange Rate Regimes. —Fixed or semi-fixed exchange rate regimes have volatility paths that are in general less smooth than their free floating counterpart. Moreover, there tends to be a correlation between the lack of smoothness and the weakness of the currency. In this article, the effects of divergence from central parity on the smoothness of the volatility are discussed within the framework of a TGARCH model. It is shown that, for various EMS rates, the divergence indicator has a statistically significant effect on the smoothness of the volatility path.     

Maximum likelihood cointegration tests of purchasing power parity: Evidence from seventeen OECD countries

Maximum Likelihood Cointegration Tests of Purchasing Power Parity: Evidence from Seventeen OECD Countries. — This paper examines the relevance of long-run purchasing power parity (PPP) during the recent floating exchange rate period, using Johansen’s maximum likelihood method for estimating and testing steady-state relations in multivariate vector autoregressive models. Thirty-two bilateral intercountry relations are considered and it is found that in many cases there exists a long-run relationship between exchange rates and international price differentials, which, however, significantly deviates from PPP in most instances.     

Capital controls and international trade finance in a dual exchange rate regime: The Belgian experience post-mortem

Capital Controls and International Trade Finance in a Dual Exchange Rate Regime: The Belgian Experience Post-Mortem. — The purpose of the paper is to model “leads and lags” capital flows on the official segment of a dual exchange market and to examine the effects of various types of capital controls imposed by authorities on the official spot and forward exchange markets. The focus of the analysis is the degree of insulation provided by a “dual exchange market cum capital controls” in face of a speculative crisis. The crucial variables in this respect are the deviation from covered interest parity and the forward risk premium. Results of the theoretical model are confronted with empirical evidence over the 1975–85 period.     

Pitfalls in panel tests of purchasing power parity

Pitfalls in Panel Tests of Purchasing Power Parity. —The results of panel unit root tests applied to real exchange rates as a test of long-run purchasing power parity (PPP) diverge much. In particular, due to misspecifications there is little evidence of the convergence of real exchange rates for the German mark. This paper provides evidence of this issue by analyzing large panels of real exchange rates vis-à-vis the German mark and the dollar. In particular, the impact of the base country and various aspects of the dynamic specifications are analyzed. Overall, the results provide strong evidence in favour of PPP as a long-run relationship.     

The trend behavior of real exchange rates: Evidence from OECD countries

The Trend Behavior of Real Exchange Rates: Evidence from OECD Countries. — This paper examines the validity of purchasing power parity (PPP) under the current float using real effective exchange rates of eleven OECD countries. The author employs a test which allows for a one-time change in the intercept and/or in the slope of the trend function. The timing of the structural break is treated as unknown and is endogenously searched from the data. It is found that for a vast majority of countries, the real exchange rate can be characterized as a stationary process with a broken trend. The paper provides support for PPP in the long run.     

A fractional cointegration approach to empirical tests of PPP: New evidence and methodological implications from an application to the Taiwan/US dollar relationship

A Fractional Cointegration Approach to Empirical Tests of PPP: New Evidence and Methodological Implications from an Application to the Taiwan/ US Dollar Relationship. —This paper applies a relatively new concept of fractional cointegration to shed some light on the validity of purchasing power parity as a long-run equilibrium condition, using the Taiwan/US dollar exchange rate. Findings suggest that, while standard tests of cointegration fail to support cointegration between nominal exchange rates, domestic and foreign prices, the fractional cointegration analysis permits deviations from equilibrium to follow a fractionally integrated process and hence captures a much wider class of parity or mean-reversion behaviour. The paper concludes by indicating areas in which fractional cointegration will be a particularly appropriate technique to unearth previously unfounded temporal characteristics.     

Assessing convergence to purchasing power parity: A panel study for ten OECD countries

Assessing Convergence to Purchasing Power Parity: A Panel Study for 10 OECD Countries. — The paper analyzes whether post-Bretton Woods real exchange rates of ten OECD countries are nonstationary so that long-run purchasing power parity (PPP) can be considered to hold. A test procedure is proposed which treats the various real exchange rates as a panel but still allows to assess the rate of convergence to PPP for each pair of currencies separately. It is shown that long-run (tradables-) PPP holds between all countries analyzed. Rates of convergence to PPP, however, are found to be quite different across countries. For most of the OECD countries convergence takes place faster than previously indicated.     

Exchange rate uncertainty and the efficiency of the forward market for foreign exchange

Exchange Rate Uncertainty and the Efficiency of the Forward Market for Foreign Exchange. — The paper investigates to what extent exchange rate uncertainty can account for the observed deviations from the forward market efficiency hypothesis (FMEH). The empirical analysis employs a simple varying parameter regression to allow uncertainty to modify the central parameters of the FMEH in a direct way. Uncertainty is proxied by significant exchange rate changes. The results indicate that there is considerable support for the FMEH if one allows the intercept term to vary over time.     

Real exchange rates and unit root tests

Real Exchange Rates and Unit Root Tests. — This paper examines monthly OECD exchange rate data (1979–1997) using univariate and panel data unit root tests. Some of these tests support the hypothesis of a unit root. But tests of cointegration reveal the existence of weak purchasing power parity relationships between bilateral nominal exchange rates and relative prices. We suggest that researchers need not conduct unit root tests on real exchange rate data when a modified version of PPP is used; or if there is a long enough time series. Given the definition of real exchange rates, the indicator should be stationary and should have intrinsic mean reverting behaviour.     

A general equilibrium evaluation of trade and industrial policy changes in Austria and Hungary

A General Equilibrium Evaluation of Trade and Industrial Policy Changes in Austria and Hungary. — Two linked static CGE models — based on 1990 data — are used to study effects of trade liberalization, problems of migration and changes in industrial policy in Austria and Hungary. The huge differences in factor endowment (Hungary is relatively labour abundant, Austria is relatively capital abundant) gives Hungary a strong competitive position in the production and export of lowwage products. Austria should have comparative advantages in products with high capital content when trading with Hungary. Although trade liberalization helps to improve welfare, much stronger effects follow from factor migration and capital accumulation through the transformation process in Hungary.     

The effects of Europe’s internal market program on production and trade: A first assessment

The Effects of Europe’s Internal Market Program on Production and Trade: A First Assessment. — The paper analyzes the extent of structural changes that have occurred inside the EC since the launching of the internal market program. The first part of the paper examines intersectoral shifts in the pattern of specialization within EC manufacturing and finds relatively little change from 1986 to 1992. The second analyzes the trade impact of the internal market program, and finds that internal and external trade creation have both prevailed. The third uses regression analysis to explain the share of intra-EC imports in total EC imports in 1986 and in 1992, and identifies the impact of the internal market program.     

Exchange rate volatility and its impact on the transaction costs of covered interest rate parity

This paper provides empirical evidence on the linkage between foreign exchange market volatility and daily 90-day covered interest rate parity (CIP) conditions of the three major exchange rates against the US dollar (US$). Markov regime shifting models were utilized to generate time series of volatility regime probabilities and these were used to explain the first and second moments of the daily deviations from and the transaction cost bands around the covered parity conditions. We find a significant positive relationship between the deviations and the regime probabilities, indicating an increasing probability of higher volatility state being associated with rising deviations (both first and second moments) from the parity condition. Similar positive relationship is found for the transaction bands. Rising (falling) probabilities of high (low) volatility regimes increased the first and second moments of the bands. Furthermore, we find a higher volatility state combined with a US$ depreciation is associated with significantly higher volatility in the daily deviations than an appreciation. Also, US$ depreciation is associated with widening transaction bands. This suggests that the level of market uncertainty was higher when the US$ was depreciating.     

State-space estimation of rational bubbles in the Yen/Deutsche Mark exchange rate

State-Space Estimation of Rational Bubbles in the Yen/Deutsche Mark Exchange Rate. — This paper considers a series that uncovered interest parity predicts to be white noise and inspects it for evidence of stochastic rational bubbles. State-space methods are used that specify a bubble component of the series as an unobserved state. The technique’s effectiveness is demonstrated by Monte Carlo experiments. One span of the series is found in which a stochastic rational bubble specification clearly dominates the white noise specification. It coincides with a period of general financial turm-oil in the associated economies, i.e. Japan and Germany during 1989 and early 1990.     

TAKING THE PUZZLE OUT OF THE PURCHASING POWER PARITY PUZZLE: AN APPLICATION IN RESPECT OF SOUTH AFRICA

This paper discusses two versions of the purchasing power parity puzzle. It presents the results of nonlinearity and nonstationarity tests in respect of the real exchange rates of the rand. It is found that the rand real exchange rate behaviour tends to be nonlinear and stationary in a majority of cases in the sample. This suggests that for the majority of the currencies in the sample, the real exchange rates of the rand are mean‐reverting, implying that the purchasing power parity relation holds in a nonlinear manner.     

DO AFRICAN COUNTRIES MOVE ASYMMETRICALLY TOWARDS PURCHASING POWER PARITY?

This paper investigates the possibility that the adjustment towards long‐run relative purchasing power parity (PPP) is dependent upon the nature of deviations from PPP that are experienced. While existing studies involving developed and less developed countries often find against PPP having employed linear tests of non‐stationarity or non‐cointegration, we employ a new cointegration test, recently advocated by Enders and Siklos and Enders and Dibooglu, that tests for an asymmetric adjustment towards parity with respect to positive and negative deviations of the real exchange rate from its equilibrium value. Using a sample often African economies with data taken from the post‐Bretton Woods floating exchange rate era, long‐run PPP holds in eight of these cases if an explicit distinction is made between positive and negative deviations. Across the sample, we find variation in the type of asymmetry experienced and the roles played by price and nominal exchange rate adjustment.     

The Danish agricultural revolution in an energy perspective: a case of development with few domestic energy sources

This article examines the case of Denmark—a country which historically had next to no domestic energy resources—for which new historical energy accounts are presented for the years 1800–1913. It demonstrates that Denmark's take‐off at the end of the nineteenth century was relatively energy dependent. This is related to Denmark's well‐known agricultural transformation and development through the dairy industry, and thus the article complements the literature which argues that expensive energy hindered industrialization, by arguing that similar obstacles would have precluded other countries from a more agriculture‐based growth. The Danish cooperative creameries, which spread throughout the country over the last two decades of the nineteenth century, were dependent on coal. Although Denmark had next to no domestic coal deposits, this article demonstrates that Danish geography allowed cheap availability throughout the country through imports. On top of this it emphasizes that another important source of energy was imported feed for cows.     

Fiscal and monetary policy in a monetary union: Credible inflation targets or monetized debt?

Fiscal and Monetary Policy in a Monetary Union: Credible Inflation Targets or Monetized Debt? —The paper examines the interrelationship between fiscal and monetary policy in a two-country monetary union. The worst scenario occurs when an independent central bank sets the nominal interest rate and responds to rising government debt/GDP ratios by monetization. The result is high inflation, high debt/GDP ratios and a large public sector. Government debt and inflation are contained if the governments bear sole responsibility for solvency, but the public sector remains excessively large. The best scenario occurs if the central bank removes the incentive for the governments to engineer surprise inflation by credible inflation targeting.     

Does antidumping stimulate FDI? Evidence from Japanese firms in the UK

Does Antidumping Stimulate FDI? Evidence from Japanese Firms in the UK. — This paper explores which factors influence the number of Japanese firms in the UK and the level of employment and fixed assets in those firms, at a highly disaggregated sector level. We are interested in whether trade policy has had a role to play in the entry and expansion of Japanese firms. The results give some support to the hypothesis that antidumping action has acted as an incentive for Japanese direct investment in the UK. However, it has a relatively modest effect —antidumping cases can explain a maximum of 8 per cent of the expansion in employment by existing Japanese firms in the UK, while they appear to have no influence on the arrival of new firms.     

Measuring marginal intra-industry trade

Measuring Marginal Intra-Industry Trade. — Trade liberalisation and adjustment: how important is intra-industry trade? This paper focuses on the appropriate measurement of intra-industry trade as indicator of structural adjustment costs. It is argued that existing dynamic versions of the Grubel-Lloyd index reflect horizontal trade only and classify vertical intra-industry trade with inter-industry trade. The paper proposes a method to distinguish between horizontal and vertical trade and applies these techniques to emerging trade between the EU and the economies of central and eastern Europe.
