Abstract: We assess the impact of internet connectivity and digital trade policies on trade and welfare. Using a bilateral measure of internet connectivity, we find a significant positive relationship between the internet and both domestic and international trade for goods and services---at the both the intensive and extensive margin. We also find that digital trade facilitation provisions in trade agreements have significantly increased trade in services but not goods. These findings highlight that digital trade determinants play different roles for goods and services: the internet is beneficial for goods trade but critical for services. Finally, using a general equilibrium model of trade, we assess the trade and welfare impacts of increased internet connectivity in developing countries and find that increases in internet use can have large positive impacts on poorly connected countries. However, it also highlights the danger of developing countries falling behind as the digital economy continues to grow.

"gegravity: General Equilibrium Gravity Modeling in Python" (2021), USITC Office of Economics Working Paper 2021-04-B.

Abstract: 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 derive measures of statistical precision for model estimates. The package is based on prominent models used in the literature and aims to make structural gravity modeling more readily accessible to researchers and policy analysts.

"One Nation, One Language? Domestic Language Diversity, Trade and Welfare" (2021), USITC Office of Economics Working Paper 2021-01-B, with Tamara Gurevich, Farid Toubal, and Yoto Yotov.

Abstract: 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 importance of shared languages for domestic integration. To highlight the general equilibrium implications of domestic language proximity, we simulate the repeal of Quebec's Bill 101, which made French an official language in Canada and established fundamental language rights for French-speakers. The analysis demonstrates that domestic language diversity has significant implications for Canada's welfare but also sizable economic consequences that stretch far beyond its borders.
