This paper studies the empirical links among factor endowments, trade, and personal income distribution. The motivation is that many developing countries have implemented radical trade reforms in recent years. These reforms have changed relative prices, induced a reallocation of resources, and...

Models on the composition of trade and growth often assume that the technological content of trade is negatively correlated with the income of the trading partner.

This paper presents a test to discriminate among behaviors of producers of exhaustible resources. The behavior of a competitive producer of an exhaustible resource should follow an Euler equation. The existence of futures markets allows us to sidestep the difficult issues related to estimating...

This paper presents a model in which trade is motivated both by preference for variety and comparative advantages. This framework is used to analyze the welfare implications of trading blocs among countries with different endowments with and without transportation costs
