Theoretical Literature review There are various models that have been constructed to describe exchange rate volatility and trade. Clark (1973) is the first to develop a theoretical framework which includes exchange rate volatility in the simple trade model. He focuses on the consequence of exchange rate volatility on the level of country’s export. He considers a representative firm that produces homogenous good under perfect competition and sells its entire products abroad. This firm does not have any importing input and it receives its income in terms of foreign currency (that is, it is facing a price uncertainty). It is also assumed that the firm is paid in foreign currency for its exports and these earnings are sold in the forward exchange …show more content…

According to first, direct channel impact, the volume of goods is affected by prices and profits that cannot be determined accurately because of exchange rate uncertainty. For example, a firm has two choices of purchasing; one is imported product and the second is a domestic substitute. They are equally valued in local currency terms using currency exchange rate levels. The firm would decide to buy domestic product if it is not clear what the exchange rate will be at the time of purchase. From this point of view, exchange rate uncertainty might affect the trade volume negatively. If hedging possibilities exist with reasonable costs it might reduce the exchange rate risk. In this case, the preceding view has to be modified. However, the forward markets could not eliminate the exchange rate uncertainty completely at reasonable cost, even in well developed forward markets financial institutions can provide only limited protection. So, exchange rate uncertainty has a direct negative effect on trade flows. The authors pointed to the second channel which is based on less straightforward explanation. According to the second channel, the exchange rate uncertainty effect depends on some decisions, which have an impact on trade flows over a longer period of time. The firm’s ability to predict the future income stream could be weakened by trading foreign …show more content…

In their paper they developed several propositions. The first proposition shows that in the absence of forward markets, a change in the mean exchange rate affects trade flows and the balance of trade. An increase in exchange rate volatility impedes both exports and imports, and surplus or deficit of the balance of trade is reduced as well. In the second proposition they tried to prove that when forward market is incorporated in the model it affects differently to exports and imports. With a forward market, one trade flow benefits and the other trade flow necessarily loses from changes in either the expected rate or the volatility. So the imports and exports are defined to be the different sides of forward market and they might be impeded or benefited from changes in exchange rate volatility. They conclude that exchange rate volatility can be detrimental or beneficial to both export and imports depending on net currency position of the
