The present paper uses the political economy model developed by Grossman and Helpman and studies the equilibrium of a game between the two countries; the home country, which exercises the trade policy for maximizing its objective function, and the foreign country, which controls the level of its capital export for the similar purpose.
It is shown that if the production costs of the two countries are identical, the equilibrium of the game in which the two countries make simultaneous move will very likely achieve free trade. (C) 1997 Elsevier Science B.V.
