Multinational Firm, Exchange Rate Risk and the Impact of Regret on Trade

This paper examines the behavior of the regret-averse multinational firm under exchange rate uncertainty. The multinational firm simultaneously sells in the home market and exports to a foreign country. We characterize the multinational firm's regret-averse preferences by a modified utility function that includes disutility from having chosen ex-post suboptimal alternatives. The extent of regret depends on the difference between the actual home currency profit and the maximum home currency profit attained by making the optimal production and export decisions had the multinational firm observed the true realization of the random spot exchange rate. We show that the conventional results that the multinational firm optimally produces less, sells more domestically, and export less abroad under uncertainty than under certainty holds if the multinational firm is not too regret averse. Using a simple binary model wherein the random spot exchange rate can take on either a low value or a high value with positive probability, we show that the multinational firm may optimally produce more, sell less domestically, and export more abroad under uncertainty than under certainty, particularly when the multinational firm is sufficiently regret averse and the low spot exchange rate is very likely to prevail
