a b s t r a c tWe formulate a two-country, two-good, two-factor, two-period-lived overlapping generations model to examine how population aging determines the pattern of and gains from trade. Two main results are obtained. First, the aging country endogenously becomes a small country exporting the capital-intensive good, whereas the younger country endogenously dominates the world economy determining the world prices, in the free trade steady state. Second, although uncompensated free trade cannot be Pareto superior to autarky, there exists a compensation scheme applied within each country such that free trade is Pareto superior to autarky.
We examine welfare and revenue effects of tariff and tax reform in a country importing final and intermediate goods, both of which are produced under imperfect competition. We consider two reform strategies. First, lower the sum of a consumption tax and a tariff on the intermediate good, and leave the sum of the consumption tax and a tariff on the final good unchanged. Second, lower the former and change the latter to leave government revenue unchanged. We specify conditions under which each reform strategy raises welfare without decreasing government revenue.
