Abstract

This paper develops a dynamic Ricardian trade model that incorporates productive infrastructures into the manufacturing sector financed by tax. We investigate the relationship between the timing of opening trade and total welfare. We also compare the two kinds of total welfare: the total welfare that a country obtains by closing international trade until it has a comparative advantage in manufacturing and then engaging in free trade and the total welfare that the country obtains by specializing in agriculture according to the law of comparative advantage from the beginning. The main results are as follows: (1) there is the optimal tax rate maximizing the total welfare; (2) an increase in agricultural productivity can accelerate the timing of opening trade, which, however, does not necessarily improve the total welfare; and (3) the total welfare under specialization in manufacturing can be higher than that under specialization in agriculture depending on conditions.
