The gegravity Python package is a collection of tools for analyzing general equilibrium, structural gravity models of international trade. It provides a framework for estimating structural gravity models, simulating counterfactual trade experiments, and conducting Monte Carlo simulations to...

Gravity models of trade have long found that estimates of trade determinants differ across both time and products. In this paper, we demonstrate that there is a systematic relationship between these two influences. Past research has found that trade factors such as distance, common language, and...

Using new data on linguistic diversity across and within countries, we examine novel channels though which language affects trade patterns and economic welfare. We find that linguistic similarity within a country accounts for about 10 percent of estimated ‘home bias’, demonstrating the...
