Do the black market and the official exchange rates converge in the long run?

Establishing cointegration and long-run convergence between the official and the black market exchange rates is a way of testing foreign exchange market efficiency. Earlier research employed the Engle-Granger or Johansen method to test for cointegration between the two rates. Since either method requires each rate to be non-stationary, exchange rates that did not possess this property had to be excluded from analysis. However, with the introduction of the bounds testing approach to cointegration, no exchange rate needs to be excluded since this relatively new technique does not require pre-unit root testing. This paper employs monthly data from 27 developing countries and the bounds testing approach to cointegration by Pesaran et al. (2001) to show that in 22 out of 27 countries, not only are the two rates cointegrated but in all countries the black market exchange rate causes the official rate to adjust and converge toward the black market rate in the long run.     

Black market exchange rate,currency substitution and the demand for money in LDCs

Mundell's conjecture in 1963 that the demand for money could depend on the exchange rate in addition to income and interest rate has received some attention in the literature by including the official exchange rate and estimating the money demand in a few developed countries. In less developed countries, since there is a black market for foreign exchange, it has been suggested that the black market exchange rate rather than the official rate should be the determinant of the demand for money in LDCs. This proposition is tested by estimating the demand for money for 25 LDCs using the bounds testing approach to cointegration. The main conclusion is that while in some LDCs, the black market rate enters into the formulation of the demand for money, in some others the official rate is the determinant. The black market premium also played a role in some countries.     

Japanese and U.S. interventions in the yen/U.S. dollar market: estimating the monetary authorities’ reaction functions

This paper uses recently released official data on the foreign exchange market interventions of the Japanese monetary authorities in the yen/U.S. dollar market during the period 1991–2001 to examine the motivation for the intervention policy. We also compare the Japanese intervention policy with the U.S. intervention policy. Our results suggest that the Japanese authorities regularly responded to deviations of the yen/U.S. dollar exchange rate from a short-term and a long-term exchange rate target. By contrast, the U.S. authorities intervened only occasionally and seemed to have merely reinforced Japanese interventions.     

Order flow in the South: Anatomy of the Brazilian FX market

This paper analyses one of the main pillars of Brazil's newly found economic resilience: a maturing FX market providing support to its managed floating exchange rate regime. I develop a microstructure model suitable to describe the Brazilian FX market, an emerging economy frequently subjected to sudden stops in capital flows. The model introduces two major changes relative to previous microstructure models. First, dealers may decide to hold overnight positions in the FX market if they find it profitable to do so. Second, customers’ demand for foreign exchange is a function of macroeconomic fundamentals, including contemporaneous feedback from exchange rate movements. The main predictions of the model are supported by a unique data set, covering all transactions between dealers and customers from the official Brazilian FX market from July 1, 1999 to June 30, 2003 (a time period in which Brazil suffered two severe external liquidity shocks).     

The investment decision of a Multinational Firm under uncertain quantity restrictions

In this paper we analyze the allocative investment decisions of a Multinational Firm (MNF) when it faces uncertain quantity restrictions such as a voluntary export restraint or a quota imposed by the host government. The model with uncertain quantity restrictions is analyzed further by introducing additional uncertainties such as a foreign tax rate, transfer prices, foreign exchange rates and foreign demand. The MNF invests more in the host country due to uncertain quantity restrictions. The risk averse MNF invests more in the host country despite its uncertain tax rate if the transfer price is less than the expected marginal revenue loss due to the uncertain quantity restriction. The uncertain transfer price leads the MNF to invest more in the foreign country if the tax rates are dissimilar between the two countries. Foreign demand uncertainty and foreign exchange rates uncertainty have the same effects on capital allocation between the host country and home country. In particular, we derive the condition under which the direction of investment is unambiguous.     

Analysis of an unannounced foreign exchange regime change

Starting in 2004 the Guyanese foreign exchange rate has been remarkably stable relative to earlier periods. This paper explores the reasons for the stability of the rate. First, the degree of concentration in the foreign exchange market has increased, thus making the task of moral suasion relatively straightforward once this policy tool comes to bear on the dominant trader(s). Second, long-term or non-volatile capital inflows make the exchange rate less susceptible to sudden reversal. Third, commercial banks, the dominant foreign exchange traders, have large outlays of assets in domestic currency, thus their desire for exchange rate stability. The econometric exercise is consistent with the notion that trader market power has contributed to lower volatility in the G$/US exchange rate. The paper also presents a model that analyzes monetary policy effects in the presence of a mark-up or threshold interest rate.     

西方外汇干预预期传导途径理论演进——兼评当前金融经济形势下中国外汇干预实践

在西方各国从固定汇率制向浮动汇率制过渡的过程中,外汇干预的力度不仅没有被削弱,反而表现出不断加强的趋势。这与外汇干预稳定汇率预期、平滑经济波动的作用是密切相关的。中国自2005年7月宣布人民币汇率形成机制改革,参考一篮子货币进行调节以后,如何通过外汇干预引导市场预期,使汇率变动向有利于宏观经济稳定的方向发展,已成为学术界研究的热点。文章旨在总结西方国家外汇干预的预期传导途径理论,并将其与中国当前所面临的世界性次贷金融经济风险相结合,希望能为中国的外汇干预实践提供助力。     

Timing of price clustering and trader behavior in the foreign exchange market: evidence from Taiwan

In this paper, I use a unique proprietary dataset from the foreign exchange market to examine the existing hypotheses on price clustering. I find that market uncertainty plays an important role in price clustering. Moreover, since trading behavior changes under different market conditions, market timing also affects the likelihood of price clustering. The results support both the price resolution hypothesis (Ball et al. J Futures Mark 5:29–43, 1985) and the negotiation hypothesis (Harris Rev Financ Stud 4:389–415, 1991). Since the data covers the interbank foreign exchange market, which is the market for the professional bank dealers, the attraction hypothesis is less likely to be a plausible explanation for price clustering in the foreign exchange market.     

Pricing-to-market in U.S. imports and exports: A time series and cross-sessional study

This paper provides a comparative study of how U.S. imports and exports prices react to exchange rate changes. It finds, through time series analyses, that while both U.S. and foreign exporters price to market, foreign exporters in general absorb a large portion of exchange rate changes by themselves while U.S. exporters pass through most of the exchange rate change to foreign currency prices. Pricing behavior of U.S. imports and, to a lesser extent, of U.S. exports varies across industries and such variation relates to industry characteristics such as market shares, product d differentiation, and capital-to-labor ratio.

Managed Floating as a Monetary Policy Strategy

Although there seems to be a broad consensus among economists that purely floating or completely fixed exchange rates (the so-called corner solutions) are the only viable alternatives of exchange rate management, many countries do not behave according to this paradigm and adopt a strategy within the broad spectrum of exchange rate regimes that is limited by the two corner solutions. Many of these intermediate regimes are characterized by significant foreign exchange market interventions and a certain degree of exchange rate flexibility with non-preannounced exchange rate targets. While academic research in this area usually concentrates on some specific aspects of intermediate regimes (such as the effectiveness of interventions or institutional aspects), managed floating has rarely been analyzed as a comprehensive monetary policy strategy. In this paper, we present a monetary policy framework in which central banks simultaneously use the exchange rate and the interest rate as operating targets of monetary policy. We explain the mechanics of foreign exchange market interventions and sterilization and we explain why a central bank has an interest of controlling simultaneously the two operating targets. We derive the monetary policy rules for the two operating targets from a simple open economy macro model in which the uncovered interest parity condition and the monetary conditions index play a central role.     

A note on transfer prices and exchange rate pass-through

The paper builds a model of a parent corporation selling an intermediate product to a foreign subsidiary. The model is used to explain the response of foreign prices to changes in the exchange rate between the country of the parent affiliate and the foreign subsidiary. The model examines this response with and without an external market for the intermediate product.     

Macroeconomic influences on the stock market

The paper studies the dynamic interactions among indicators of economic activity, such as industrial production, interest rate and exchange rate, the performance of the foreign stock market, oil prices, and stock returns to examine whether economic activity movements affect the performance of the stock market for Greece. The empirical evidence suggests that stock returns do not lead changes in real economic activity while the macroeconomic activity and foreign stock market changes explain only partially stock market movements. Oil price changes explain stock price movements and have a negative impact on macroeconomic activity.     

Extreme risk spillovers between crude palm oil prices and exchange rates

This study is the first attempt to examine the extreme risk spillovers between Malaysian crude palm oil (CPO) and foreign exchange currencies of the three largest CPO importers: India, the European Union and China throughout the global financial crisis. Using daily data of three currencies, CPO spot and futures from 2000 to 2018, our results show: First, before the crisis, the unexpected change in foreign exchange rates is the primary driver of risk spillover to the CPO market. Second, during the crisis, the extreme movement of CPO spot returns is dominant in the Malaysian exchange rates relative to the euro. Third, after the crisis, the spillover flows from the CPO market to the foreign exchange market. Overall, our findings show the importance of CPO pricing dynamics in mitigating foreign exchange risk over the crisis period. This paper contributes to the extant literature by recognizing the effect of risk spillover on the targeted foreign exchange rate for portfolio allocation.     

An objective function for simulation based inference on exchange rate data

The assessment of models of financial market behaviour requires evaluation tools. When complexity hinders a direct estimation approach, e.g., for agent based microsimulation models, simulation based estimators might provide an alternative. In order to apply such techniques, an objective function is required, which should be based on robust statistics of the time series under consideration. Based on the identification of robust statistics of foreign exchange rate time series in previous research, an objective function is derived. This function takes into account stylized facts about the unconditional distribution of exchange rate returns and properties of the conditional distribution, in particular, autoregressive conditional heteroscedasticity and long memory. A bootstrap procedure is used to obtain an estimate of the variance-covariance matrix of the different moments included in the objective function, which is used as a base for the weighting matrix. Finally, the properties of the objective function are analyzed for two different agent based models of the foreign exchange market, a simple GARCH-model and a stochastic volatility model using the DM/US-$ exchange rate as a benchmark. It is also discussed how the results might be used for inference purposes. Research has been supported by the DFG grant WI 20024/2-1/2. We are indebted to two anonymous referees of this journal, Leigh Tesfatsion, Patrick Burns and other participants of the CEF’06 conference in Limassol for helpful comments on preliminary versions of this paper.

Valuation effects of capital inflows: Evidence from emerging market economies

This paper studies valuation changes of capital inflows in 19 emerging market economies (EMEs). In most of the EMEs, we find that there are significant valuation changes and a positive rate of return on external liabilities by foreigners. Furthermore, the nonlinear effects of exchange rate movements on valuation changes are investigated using panel smooth transition regression models. Empirical results show that the transition is centered at approximately −22.3% of exchange rate change, which implies that when the exchange rate appreciates more than this level, foreign investment value gains increase considerably.
