Theory of the firm in relation to exchange rates,import substitution and export

Neoclassical theory deals with the profit maximizing beheviour of the firm in a closed economy. Once an open-economy condition is introduced, the impact of the exchange rate on the cost and price parameters of the firm and, consequently, its import substitution and export decisions becomes relevant. A model is presented with case studies in which, given the exchange rate, the firm seeks to determine the optimal level of import substitution, output and export with the objective of maximizing its profit. In today's competitive world when countries are liberalizing and moving towards an open trade regime, the influence of exchange rates on the decision-making processes of firms is bound to be significant. An approach which provides them with a methodology for spelling out their options and making optimal choices is, therefore, of considerable practical interest.
