Exports and Indirect Hedging of Foreign Currency Risk

We present a model of a risk-averse competitive exporting firm under exchange rate risk. Direct hedging instruments are not available. However, there are domestic assets whose prices are correlated to the foreign currency. We consider a market for futures contracts in these domestic assets and investigate the firm's indirect hedging and export policy. It is shown that the availability of many financial instruments correlated with foreign exchange may, under some circumstances, provide the same results as a perfect hedge.

Hedging exchange rate risk: The multiperiod case

We analyse production and hedging in a multiperiod framework for a risk-averse exporting firm facing a random exchange rate. We extend the separation theorem to this multiperiod model. Our study shows that unbiased currency forward markets in all periods do not imply standard full hedging. Under some conditions, the firm tends to overhedge compared to the one-period hedging models.     

Exchange rate volatility,international trade and labour demand

The purpose of this study is to assess under what conditions exchange rate volatility generates a positive effect on an exporting firm’s labour demand. As the exchange rate volatility increases, so does the value of the export option, provided that firms are flexible with respect to international trade. Higher volatility increases the potential gains from trade and can increase the demand for labour. The firm’s trade flexibility can be interpreted as a real hedging strategy when financial markets are incomplete. In many newly industrializing countries and emerging economies financial markets are imperfect or risk sharing markets are just starting to develop at a rather slow pace.     

The firm under uncertainty: real and financial decisions

This paper examines the interplay between the real and financial decisions of the competitive firm under output price uncertainty. The firm faces additional sources of uncertainty that are aggregated into a background risk. We show that the firm always chooses its optimal debt–equity ratio to minimize the weighted average cost of capital, irrespective of the risk attitude of the firm and the incidence of the underlying uncertainty. We further show that the firm’s optimal input mix depends on its optimal debt–equity ratio, thereby rendering the interdependence of the real and financial decisions of the firm. When the background risk is either additive or multiplicative, we provide reasonable restrictions on the firm’s preferences so as to ensure that the firm’s optimal output is adversely affected upon the introduction of the background risk.

Market structure and multiperiod hedging

This paper develops a multiperiod hedging model for a competitive risk-averse international firm. We study the optimal sequential hedging strategy and analyze the impact of the structure of available risk sharing markets on the firm's export decision. As a main result, we find that the number of risk sharing markets critically affects the export level while the timing of these markets is inconsequential.     

Hedging with mismatched currencies

This article presents a model of a risk-averse multinational firm facing risk exposure to a foreign currency cash flow. Forward markets do not exist between the firm's own currency and the foreign currency, but do exist for a third currency. Because a triangular parity condition holds among these three currencies, the available forward markets, albeit incomplete, provide a useful avenue for the firm to indirectly hedge against its foreign exchange rate risk exposure. This article offers analytical insights into the optimal cross-hedging strategies of the firm. In particular, the results show that separate unbiasedness of the forward markets does not necessarily imply a perfect full hedge that eliminates the entire foreign exchange rate risk exposure of the firm. The optimal cross-hedging strategies depend largely on the firm's marginal utility function and on the correlation of the random spot exchange rates. © 1999 John Wiley & Sons, Inc.

Foreign production and international hedging in a multinational firm

This paper presents a model of a risk-averse multinational firm under exchange rate risk. The firm, which owns and controls assets in two countries, is engaged in foreign production, sales, and foreign currency forward contracting. The implications of the existence of forward markets in global market decisions are discussed. It is shown that a separation theorem holds. The optimal hedging behavior is also discussed.     

Export,Exchange Rate Risk and Hedging: The Duopoly Case

Abstract. This paper studies a Cournot duopoly in international trade with firms exposed to exchange rate risk. A hedging opportunity is introduced by a forward market on which one firm can trade the foreign currency. We investigate two settings: First, we assume that hedging and output decisions are taken simultaneously. It is shown that hedging is exclusively done for risk‐managing reasons as it is not possible to use hedging strategically. Second, the hedging decision is made before the output decisions. We show that hedging is not only used to manage the risk exposure but also as a strategic device.
