Exchange rate volatility and fluctuations in the extensive margin of trade

The existing evidence for exporters׳ entry and exit in response to exchange rate movements is based on either low frequency data or a sample with large devaluations. Using quarterly data of U.S. bilateral trade with 99 countries, this study provides new evidence that the extensive margin of trade fluctuates over the business cycle. First, I show that the extensive margin of exports to the U.S. and the extensive margin of imports from the U.S. are more volatile than the output of almost all trading partners. Next, I find that fixing exchange rates with the U.S. dollar, having a free trade agreement with the U.S., and an increase in country size is significantly associated with the stability of the pattern of trade with the U.S.     

The US current account,sustainability, and the international monetary system

In this paper, we examine the sources of the US current account imbalances and discuss the role of the international monetary system in enabling the US in carrying such external deficits. There is evidence that the stochastic properties of the US current account are not compatible with the intertemporal national budget constraint. We argue that this is likely to be related to the dominant role of the U.S. dollar as an international reserve asset, which allows the US to meet international demand for safe assets and allows borrowing at very low interest rates. Results from a structural VAR model indicate that temporary shocks dominate the current account in the short run, whereas domestic permanent supply shocks and preference shocks contribute significantly to US current account movements in the long run. To the extent that temporary shocks stem from aggregate demand, stabilizing aggregate demand is important in achieving long-term sustainability in the current account. Finally, the paper discusses the role of the international financial system and the international role of the U.S. dollar in contributing to US external imbalances.

The effects of dollar appreciation on sectoral labor market adjustments: Theory and evidence

We examine the extent to which exchange rate fluctuations affect sectoral employment and wages in the United States. We introduce a theoretical rational expectation model that decomposes movements in the exchange rate into anticipated and unanticipated components. The model demonstrates the effects of demand and supply channels on the response of the nominal wage and labor employment to changes in the exchange rate. The evidence indicates that the deflationary effect dominates on industrial nominal wage in manufacturing and transportation industries in the face of dollar appreciation. More importantly, there is evidence of a decrease in employment growth in several industries in response to dollar appreciation, which is statistically significant in construction and at the aggregate level. This evidence is consistent with a decrease in labor demand given the loss of competitiveness of U.S. products following dollar appreciation. There are negative effects of dollar appreciation on labor market conditions in the United States. Nonetheless, dollar appreciation is consistent with an increase in employment growth in the mining sector where the share of imports is the largest among U.S. industries.     

Nonlinearities in exchange rate determination in a small open economy: Some evidence for Canada

We analyze bilateral Canadian-US dollar exchange rate movements within a Markov switching framework with two states, one in which the exchange rate is determined by the monetary model, and the other in which its behavior follows the predictions of a Taylor rule exchange rate model. There are a number of regime switches throughout the estimation period 1991:2–2008:12 which we can each relate to particular changes in Canadian monetary policy. These results imply that an active monetary policy stance may account for nonlinearities in the exchange rate-fundamentals nexus. The strong evidence of nonlinearities also confirms the notion that exchange rate movements cannot be explained exclusively in terms of any one particular exchange rate model.     

Dynamics of floating exchange rate: how important are capital flows relative to macroeconomic fundamentals?

While focusing on traditional macroeconomic fundamentals, existing literature has provided little understanding of impacts of various types of capital flows on the dynamics of floating exchange rates. This paper develops a structural VAR model that takes into account macroeconomic fundamentals as well as various types of capital flows in explaining the fluctuations of the floating exchange rates of the Australian dollar, the Canadian dollar, and the U.S. dollar over 1980–2004. Our main findings are as follows. Among the traditional macroeconomic fundamentals, relative interest rate still plays a significant role in explaining exchange rate dynamics for all three currencies. Capital flows play an important role in explaining the fluctuations in the Australian dollar and the Canadian dollar, but not the U.S. dollar. In particular, portfolio investment is the most explanatory factor for the Australian dollar and the Canadian dollar. For the U.S. dollar, relative interest rate explains the most of exchange rate fluctuations, especially in the medium to the long run. The results indicate that capital market transactions do play important roles in determining exchange rates; however, it may have different implications for the reserve currencies versus the non-reserve currencies. Further research is needed.     

The effect of exchange rate volatility on U.S. bilateral trade with Africa: A symmetric and asymmetric analysis

The impact of exchange rate volatility on U.S. trade with the world or on U.S. trade with major partners has been assessed by many researchers, but none have considered the case of U.S. trade with African nations. We fill this gap by assessing the symmetric and asymmetric impact of the real bilateral exchange rate volatility between the U.S. dollar and each African partner’s currency on the U.S. trade flows with each of the 20 partners from Africa. We found asymmetric short-run effects of exchange rate volatility on almost all U.S. exports to and imports from each of the 20 countries. In addition, significant long-run asymmetric effects were discovered in the case of U.S. exports to 15 countries and U.S. imports from 12 countries. Our findings are partner-specific.     

Comparing exchange rate forecasting models: Accuracy versus profitability

In this paper we compare the rankings of alternative exchange rate forecasting models using two different evaluation criteria: forecast accuracy and profitability in forward market speculation. Either or both of these criteria may be useful to the practitioner depending on the forecasting application. We use both time-series and static and dynamic structural models to construct forecasts for the Canadian dollar/U.S. dollar and German mark/U.S. dollar exchange rates over the period 1976 :12–1984: 9. Our results confirm earlier findings that simple time-series models such as the random walk rank highest in forecast accuracy. The random walk also ranks high in terms of profitability for the German mark, but for the Canadian dollar the profitability rankings are quite different than the accuracy results. For both currencies we find that some models are very profitable in forward speculation, which is evidence against the speculative efficiency hypothesis but may be consistent with the existence of risk premia in foreign exchange markets.     

Exchange rate misalignments,capital flows and volatility

This study investigates the effect of three dimensions of exchange rate misalignments—(i) distance (absolute misalignments), (ii) direction (overvaluation or undervaluation), and (iii) degree (small or large misalignments)—on the overall as well as short-cycle exchange rate volatility. Using data from 1988 to 2014, we find that relative PPP-based exchange rate misalignments increase exchange rate volatility. For developed and developing countries, this increase in volatility is driven mainly by large undervalued misalignments of the U.S. dollar. This finding might be linked to interventions targeting the loss in domestic producers’ competitiveness in global markets. Interestingly, in the case of developed countries, we find this adverse effect on exchange rate volatility also for small absolute misalignments; exchange rate movements close to equilibrium may be associated with ambiguity with respect to future movements in developed countries, which can result in higher exchange rate volatility. Further, the results suggest that, when the dollar is highly undervalued, capital flows have a stabilizing effect on exchange rate volatility in developed countries but a destabilizing effect in developing countries. The finding is consistent with investors’ strategy of taking exchange rate overvaluation and undervaluation into account when engaging in cross-border investments.     

The exchange value of the dollar and the U.S. trade balance: An empirical investigation based on cointegradon and Granger causality tests

This article performs tests of Granger causality in the relationships between the nominal ad real exchange rates of the dollar and the U.S. trade balance as well as its price and quantity components over the period 1973:IIQ–1989:IIIQ. Our results suggest: (i) weak statistical evidence of unidirectional causality running from the nominal exchange rate to import prices and nominal trade balance (ii) no statistical support for the proposition that the real exchange rate simply “accommodates” changes in the real trade balance, and (iii) strong (no) causal links between the nominal and real exchange rates and export (import) volume. We tentatively conclude that movements in the exchange rate have a rather limited effect on the trade balance and that this effect is more likely to materialize on the export side of the trade balance.     

Exchange rate determination: Empirical evidence for the Greek drachma

We examine the monetary approach to the exchange rate from several perspectives, using monthly data on five Greek bilateral exchange rates. Using the Johansen multivariate cointegration technique we demonstrate that the monetary model is validate as a long-run relationship. Moreover, upon imposing the long-run monetary model restrictions we find that the proportionality of the exchange rate to relative monetary aggregates is accepted for the bilateral exchange rate of the Greek drachma with respect to the US dollar, the deutschemark, the pound sterling, the French franc and the Italian lira. Finally, using the Hansen-Johansen (1993) testing procedure, we reject the hypothesis of sample independency of the dimension of the cointegration space in all cases, apart from the German one, but we accept the hypothesis that the estimated coefficients do not display instabilities in recursive estimations.     

U.S. interest rates and the exchange value of the dollar: A test of causality

This study examines the causal relationship between interset rates and the exchange value of the dollar using Granger causality tests. Cointegration tests show that error correction models are not necessary in this case. The results suggest that the combination of short- and long-term U.S. interest rates, in nominal or real terms, Granger cause the exchange value of the dollar, and that the difference between nominal domestic and foreign rates does not Granger cause the exchange value of the dollar. This result supports the proposition that budget deficits contribute to trade deficits.     

The currency denomination of external European Union imports after European Union expansion

Using a multiple market model I examine the impact of euro expansion on the optimal currency denomination of external EU imports. Results suggest euro invoicing will increase more in the EU-expansion country than in the original EU. Exporting firms from dollar bloc countries (the U.S. or countries with fixed exchange rates with the dollar) are more likely to invoice in the euro if price discrimination is already optimal. Firms from outside the dollar bloc are more likely to use the euro when the original EU market is relatively large or transaction costs of exchanging the euro are relatively small.     

Bond market co-movements,expected inflation and the GBP-USD equilibrium real exchange rate

Since the end of the fixed rates in 1973 and after the European Monetary System (EMS) sterling dismissal in 1992, the value of the pound has undergone large cyclical fluctuations on average. Of particular interest to policy makers is the understanding of whether such movements are consistent with the lack or not of a correction mechanism to some long-run equilibrium. The purpose of the present study is to understand those dynamics, how the external value of the British sterling (GBP) relative to the US dollar (USD) evolved during the recent floating experiences, and what have been the driving forces. In this paper we assume the real exchange rate to be determined by forces relating to the goods and capital market in a general equilibrium framework. This entails testing the purchasing power parity (PPP) and the uncovered interest parity (UIP) together. In doing so, we model inflation expectations explicitly. Our findings have two important implications, both for monetary policy. First, we show that some of the observed changes in the bilateral real exchange rate cannot be solely attributed to changes in inflation rates, but, also to capital markets. Secondly, we find a weaker behavior of the US bond rate on international markets, possibly explained by the special US dollar status of World reserve currency.     

Nonlinear adjustment,purchasing power parity and the role of nominal exchange rates and prices

Although the literature on purchasing power parity (PPP) is rich in controversy, the relative contribution of prices and nominal exchange rates to real exchange rate movements which restore PPP disequilibria has rarely been put under any close scrutiny. This paper as a first step applies a cointegrated VAR framework to test for stationary real exchange rates and linear adjustments in prices and nominal exchange rates. As a second step, ESTR error correction models are fitted to test whether nonlinear error correctional behaviour characterizes the data. The results clearly indicate that the nominal exchange rate is responsible for the nonlinear mean reverting behaviour in real exchange rates and also mainly drives overall adjustment. Applying dynamic stochastic simulations based on the estimated models, this study also confirms recent results that the half-life times of real exchange rate shocks are significantly smaller than the consensus benchmark of 3–5 years.     

Impact of exchange rate volatility on commodity trade between U.S. and China: is there a third country effect

Impact of exchange rate uncertainty on trade flows still continues to dominate the literature. Most previous research has used aggregate trade data between one country and the rest of the world or between two countries at a bilateral level. A recent study, however, considered the trade between the U.S. and China at the commodity level, but excluded the ??third-country?? effect in its analysis. In this paper, we consider the commodity trade between the U.S. and China one more time and investigate whether volatility of the real U.S. dollar-Canadian dollar has any implication on the trade flows between the U.S. and China. The answer happens to be in the affirmative, though a more significant third-country effect is found in the short run as compared to the long run.     

A revisit to economic exposure of U.S. multinational corporations

To shed light on the influence of U.S. major trade partners’ currencies on MNCs’ firm values, this study investigates the asymmetric effects and the determinants of appreciated and depreciated economic exposure of the U.S. MNCs. Our empirical results reveal several findings: (1) The influences of exchange rate fluctuation on stock returns vary enormously for different currencies. (2) During the U.S. dollar appreciating period, MNCs benefit very little from this appreciation against major trade partners’ currencies, but most MNCs see harmful impacts from a U.S. dollar appreciation against the Brazilian real. (3) During the U.S. dollar depreciating period, most U.S. MNCs benefit from this depreciation against the European Monetary Union’s euro, Mexican new peso and Brazilian real; however, they overall suffer losses against the Chinese yuan, Japanese yen, and British pound. (4) The level of foreign sales is the key determinant of economic exposure.     

Oil prices,stock returns,and exchange rates: Empirical evidence from China and the United States

Employing the diagonal BEKK model as well as the dynamic impulse response functions, this study investigates the time-varying trilateral relationships among real oil prices, exchange rate changes, and stock market returns in China and the U.S. from February 1991 to December 2015. We highlight several key observations: (i) oil prices respond positively and significantly to aggregate demand shocks; (ii) positive oil supply shocks adversely and significantly affect the Chinese stock market; (iii) oil price shocks persistently and significantly impact the trade-weighted US dollar index negatively; (iv) the US and China stock markets correlate positively just as the dollar index and the exchange rate does; (v) a significant parallel inverse relation exists between the US stock market and the dollar and between the China stock market and the exchange rate; and (vi) the Chinese stock market is more volatile and responsive to aggregate demand and oil price shocks than the US stock market in recent years.     

Pricing‐to‐Market and Market Structure*

Stimulated by imperfect competition/sticky prices framework of the new open economy macroeconomics, empirical research has reconsidered the role of exchange rates in international adjustment. This paper reassesses the link between exchange rates and traded good prices by estimating pricing‐to‐market equations for the five main euro area countries over the period 1990–99. We minimize selection biases by keeping all manufacturing products and all destination markets and show that exchange rate pass‐through (ERPT) is much larger, almost complete, than previously estimated. Thanks to a huge variability in terms of exchange rate variations, products and destination markets, we can map differences in ERPT into market structures and, at the same time, reconcile our results with the empirical literature. We find that ERPT is highly incomplete for sales by oligopolistic industries into advanced economies, indeed in the order of 50–60% as previously estimated. ERPT is instead almost complete in emerging and developing economies where therefore exchange rate movements can help adjust external imbalances. We also find that ERPT is largely asymmetric: it is almost complete after an appreciation of the exporter's currency, rather incomplete after a depreciation. This result is very robust across specifications.     

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.
