By reducing the negative correlation between local prices and productivity shocks, trade liberalization changes the volatility of returns. In this paper, we explore the second moment effects of trade. Using forty years of agricultural micro-data from India, we show that falling trade costs...

We develop a versatile general equilibrium framework to determine the spatial distribution of economic activity on any surface with (nearly) any geography. Combining the gravity structure of trade with labor mobility, we provide conditions for the existence, uniqueness, and stability of a...

What is the best way to reduce trade frictions when resources are scarce? To answer this question, we develop a framework that nests previous general equilibrium gravity models and show that the macro-economic implications of these various models depend crucially on two key model parameters,...
