Abstract: Traditional theories of international trade as the Ricardian-Model determine a flow of goods between two countries based on the setting of comparative advantage. Incorporating the main part of international trade to take place between countries of the same economical strength integrated trade theories have been developed, reckoning the consumer’s preference for variety. Helpmann (1999) develops a modification of an international trade system, considering differences in technology, factor price and trading cost. Latest research has especially been concerned with a constitution of a monopolistic competition system with heterogeneous firms, considering effects of trade liberalization. In Tybout and Erdem (2003) the liberalization leads to a reduction in firm mark-ups. This effect results from the thesis that a constant elasticity of substitution denotes fix markups. |
