Cash Position, Credit Risk and Hedging

In choosing between forward and spot hedging, cash constrained and/or high credit risk firms are more likely to hedge foreign currency transactions forward than firms of greater quality. This arises because the cost of the levered component of a spot hedge is greater than the cost of the unlevered component and this premium increases with higher credit risk. For given cash and credit characteristics, importers are more (less) likely to hedge forward than exporters if transactions costs in the home security market are less (more) than the corresponding costs in the foreign security market.     

A multivariate GARCH in mean approach to testing uncovered interest parity: evidence from Asia-Pacific foreign exchange markets

The existence of time-varying risk premia in deviations from uncovered interest parity (UIP) is investigated based on a conditional capital asset pricing model (CAPM) using data from four Asia-Pacific foreign exchange markets. A parsimonious multivariate generalized autoregressive conditional heteroskedasticity in mean (GARCH-M) parameterization is employed to model the conditional covariance matrix of excess returns. The empirical results indicate that when each currency is estimated separately with an univariate GARCH-M parameterization, no evidence of time-varying risk premia is found except Malaysian ringgit. However, when all currencies are estimated simultaneously with the multivariate GARCH-M parameterization, strong evidence of time-varying risk premia is detected. As a result, the evidence supports the idea that deviations from UIP are due to a risk premium and not to irrationality among market participants. In addition, the empirical evidence found in this study points out that simply modeling the conditional second moments is not sufficient enough to explain the dynamics of the risk premia. A time-varying price of risk is still needed in addition to the conditional volatility. Finally, significant asymmetric world market volatility shocks are found in Asia-Pacific foreign exchange markets.     

Relative risk aversion and the transmission of financial crises

We study how investor behavior affects the transmission of financial crises. If investors exhibit decreasing relative risk aversion, then negative wealth shocks increase the risk premium required to hold risky assets. We integrate this into a second generation model of currency crises which allows for contagion through changes in fundamentals. Investor behavior can be a transmission channel of financial crises, as changes in risk premia increase the coverage ratio and makes the defense of a peg less attractive for the policy maker. The feedback effect of the risk premia on the probability of devaluation also makes multiple equilibria more likely. The possible stabilization effects of capital controls and a Tobin tax on the international transmission of financial crises are also studied.     

Capital control and exchange rate volatility

The study offers one conceptual and theoretical framework for evaluating the economic effects of a trading tax on foreign exchange transactions. Taxes and the price stickiness mechanism are taken into account in the model. When prices are flexible, full monetary neutrality can be obtained even in the short-term. Intuitively, taxes on foreign exchange transactions discourage speculation by rising currency trading costs, and, thus, increase the stability of the exchange rate. Finally, the results show that not only the exchange rate but consumption, investment and employment will become less volatile by imposing trading taxes on foreign exchange transactions.     

The Use of Forward Contracts for Hedging Currency Risk

This paper derives an optimal rule for hedging currency risk in a general utility framework. Ex ante hedging performance of the forward markets is examined using the optimal hedge ratio derived from the utility model and an optimal rule derived from another model (excess return per unit risk) suggested in the hedging literature. Results of this study indicate a naive (one-to-one) hedge performs similarly to the optimal hedge ratios under either model. An implication of this study is that financial managers of multinational firms should simply follow a one-to-one rule when hedging foreign exchange risk in the forward markets.     

Entry of foreign banks in Shanghai: implications for business strategies in an increasingly competitive market

This paper uses a simple mean‐variance choice model as the basis of a duration analysis of the factors determining the decision of a foreign bank to establish a branch in Shanghai, the fast developing financial centre in China. Bank attributes, namely region of origin, parent bank size, the number of international branches and their branch network in China, have a significant impact on the time to entry. A country's share of total foreign direct investment in Shanghai also significantly affects the entry decision. The attributes facilitating entry also provide the foreign bank with a competitive advantage in its foreign currency transactions in Shanghai. However, with the ensuing market liberalisations after China's WTO accession, the entrants' competitiveness may not be sustained in the local currency market, especially following the proactive business strategies of Chinese banks and the protectionist measures of the government. It is expected that only a small number of the entrants will be able to emerge as big market players in the growing domestic currency market in Shanghai.

UK Multinationals' Effective Use of Financial Currency‐Hedge Techniques: Estimating and Explaining Foreign Exchange Exposure Using Bilateral Exchange Rates

Using a unique dataset of recently available accounting disclosures, this study examines the relationship between UK multinationals' stock returns and changes in the principal exchange rate to which each firm is most exposed. We find more firms with significant foreign exchange exposure estimates using this firm‐specific principal currency data, compared with those exposure estimates using the broad exchange rate index data prevalent in prior studies. The cross‐sectional variations in such principal‐currency exposure estimates are explained in relation to the financial currency‐hedge techniques that each firm specifically identifies as being used to manage its currency risk. In particular, we provide evidence that firms effectively use foreign currency derivatives and foreign‐denominated debt to reduce the currency risk associated with the bilateral exchange rate to which they are most exposed. This study is important to both the academic and the practitioner communities because it represents the first use of publicly available UK disclosures to improve the estimation and explanation of foreign exchange exposure.     

China's entry to the WTO: managerial implications for foreign banks

This paper shows that particular attributes of foreign banks, viz. size of assets, number of branches, and links to the Asian network, have significant impacts on their decision to engage in business transactions in China's domestic currency, Renminbi. Access to these markets will expand upon China's entry to the WTO and these attributes will also help the foreign bank to manage liquidity and credit risks more effectively when dealing with their Chinese customers. Other foreign banks without these attributes will have to adopt aggressive employment policies or restrict themselves to providing services to joint ventures in China.

Tax wedges,bid-ask spreads,and international financial parity conditions

Tax wedges do not induce a priori inconsistencies in the international Fisher effect nor do they render forward rates biased predictors of future spot rates once proper account is taken of the bid-ask spreads present in spot and forward foreign currency transactions.

Expectations Formation and Risk in Three Financial Markets: Surveying What the Surveys Say

This paper attempts to provide a logical overview of the literature which exploits survey data to examine issues of expectations formation and risk aversion in financial markets. Our survey suggests that: short term expectations are excessively volatile and exhibit bandwagon effects, while longer term expectations appear to be regressive and therefore stabilising; in bond and foreign exchange markets the standard result of forward rate biasedness is due in part to time-varying premia; recent research using disaggregate foreign exchange survey data demonstrates the importance of heterogeneous expectations.     

Equity block transfers in transition economies: Evidence from Poland

This paper investigates valuation effects of share block transfers and employs agency theory to explain the determinants of equity block premia. A sample of transactions from Poland is used to measure benefits and costs of ownership concentration. Block premia are found to be remarkably low and comparable with those for the most developed economies. Shareholders expect to benefit from intensified monitoring and from corporate restructuring resulting from block acquisitions. Still, shareholders are wary of expropriation stemming from the extraction of private benefits of control by block holders. The opportunities to extract such benefits depend on relative power of investors.     

Comprehensive analysis of market conditions in the foreign exchange market

We investigate quotation and transaction activities in the foreign exchange market for every week during the period of June 2007 to December 2010. A scaling relationship between the mean values of number of quotations (or number of transactions) for various currency pairs and the corresponding standard deviations holds for a majority of the weeks. However, the scaling breaks in some time intervals, which is related to the emergence of market shocks. There is a monotonous relationship between values of scaling indices and global averages of currency pair cross-correlations when both quantities are observed for various window lengths ?? t.     

Demand and supply drivers of foreign currency loans in CEECs: A meta-analysis

We present a meta-analysis of the determinants of foreign currency loans in Central and Eastern Europe. We base our inferences on the results of 21 studies that provide around 800 estimated coefficients for seven determinants of foreign currency loan demand. Our results indicate that, on average, supply factors (foreign currency deposits and the minimum variance portfolio ratio) appear to play a more significant role than demand factors (interest rate differentials) of foreign currency loans. Moreover, we show that the estimates reported in the literature tend to be influenced by selected study characteristics such as the econometric methodology and their regional focus.     

Structural vulnerability and resilience to currency crisis: Foreign currency debt versus export

Is there any factor that is not analyzed in the literature but is important for preventing currency crises? I argue that exports are an important factor to prevent currency crises that has not been frequently analyzed in the existing theoretical literature. Using the third generation model of currency crises, I derive a simple and intuitive formula that captures an economy’s structural vulnerability characterized by the elasticity of exports and repayments for foreign currency denominated debt. I graphically show that the possibility of currency crisis equilibrium depends on this structural vulnerability and also analyze how this vulnerability impacts the effectiveness of monetary policy response.     

The Association Between the Level of International Diversification and Risk

This study analyzes the association between the degree of international involvement (DOI) and risk. Both systematic risk (measured by the market model beta) and total risk (measured by variance of return) are analyzed. Betas of fully diversified foreign stock portfolios are shown to be lower than betas of domestic portfolios. Therefore, if the beta of a foreign investment by a U.S. firm is equal to the average beta of an investment in the foreign market, then overall firm beta will decrease as DOI increases (hypothesis). While total risk might be decreased due to the diversification provided by increasing DOI, currency, political, and other risks could cause total risk to increase. Briefly, the results of this study suggest that (1) systematic risk is negatively related to DOI even after controlling for other factors known to be associated with systematic risk, (2) intertemporal changes in systematic risk are negatively related to intertemporal changes in DOI, and (3) in contrast to the results of previous research, DOI is not negatively related to total risk and, in fact, intertemporal changes in total firm risk are marginally positively related to intertemporal changes in DOI.
Our results suggest that increasing DOI decreases systematic risk but increases total risk. Year to year changes in both beta and variance of return appear to be related to year to year changes in DOI. While currency, political, and other risks of international operations increase total risk, these risks apparently can be diversified away resulting in a beta that behaves as a blending of its previous level and the beta of a fully diversified investment in the foreign market.     

Currency Mismatching

This paper considers a firm domiciled in an emerging market, modeling its decision to denominate its debt in a combination of its domestic currency and a foreign currency, that is, the dollar. The objective is to determine those situations when the firm is motivated to engage in currency mismatching, that is, denominating a higher percentage of its debt in dollars than what is warranted by its dollar‐denominated sales. The following factors are shown to induce greater currency mismatching: speculative capital flows into the emerging market, reduced ability to price discriminate between domestic and foreign customers, increased exchange rate stability, and lower risk‐aversion.

The future of the dollar–euro exchange rate

Monetary unification in Europe is expected to produce a major new international currency, which may compete with the U.S. dollar as the currency of choice in foreign exchange transactions, financial asset markets and central bank reserves. This study considers two important issues regarding the euro: its global role as medium of exchange, unit of account, and store of value and its position relative to the U.S. dollar. Among the main considerations are differences in cyclical behavior, inflation differentials, trade patterns and capital flows, and risk-return assessments. External diversification of private portfolios and of central banks’ reserve holdings will play a key role in determining the euro’s exchange rate. Overall, despite its rough start, we argue that the euro may emerge as a challenger to the U.S. dollar.     

Risk premia in general equilibrium

This paper shows that non-linearities from a neoclassical production function alone can generate time-varying, asymmetric risk premia and predictability over the business cycle. These empirical key features become relevant when we allow for non-normalities in the form of rare disasters. We employ analytical solutions of dynamic stochastic general equilibrium models, including a novel solution with endogenous labor supply, to obtain closed-form expressions for the risk premium in production economies. In contrast to an endowment economy with constant investment opportunities, the curvature of the consumption function affects the risk premium in production economies through controlling the individual's effective risk aversion.     

Immunizing Foreign Exchange Contracts Against Swap Rate and Volatility Risks

Swap rate risk, also called the problem of' "maturity gaps," originates from foreign currency holdings whenever the involved contracts have differing maturities. Such differing maturities give rise to a sensitivity of the portfolio values with respect to the "swap rate," or differential between the relative interest rates in two countries. Volatility risk, which typically affects only currency contracts having asymmetric payoffs (such as currency options), gives rise to a sensitivity of portfolio values with respect to changes in the exchange rate volatility. In this article we show how currency portfolios may be immunized , or made insensitive, to both swap rate risk and volatility risk, in the sense of Macaulay's (1938) classical treatment of interest rate risk. The European currency option contract is the primary subject of our discussion, since we show that both ordinary forward contracts and other complicated currency contracts are equivalent to suitable combinations of European currency options.
