Outline of Final Research Achievements

We investigate how trade liberalization affects firm productivity using a general oligopolistic equilibrium model with division of labor. We analyze the impact of both tariff reduction and a decrease in the number of non-trading sectors on firm productivity and welfare.
We obtain the following results:(1) A decrease in the tariff rate and an increase in the number of trading sectors increase wage rate.(2) A decrease in tariff rate reduces firm productivity of non-trading sectors and increases firm productivity of trading sectors. (3) An increase in the number of trading sectors decreases firm productivity of both non-trading sectors and trading sectors. However, it increases the firm productivity of the newly trading sectors.
