This is the second course in a two-part sequence. We study recent developments in empirical international trade and focus on estimation methods drawn from the field of empirical industrial organization. The reading materials include a mix of trade theory papers, empirical trade papers and industrial organization applications. The sessions will combine expositions by the lecturer, presentations by students and 'hands-on' coding, mostly in Matlab and Stata. We will discuss demand-side heterogeneity and quality, and study discrete-choice models for demand estimation. We will discuss models with demand-side driven heterogeneous markups. The final section of the course will focus on information frictions and the estimation of discrete choice problems with adverse selection and moral hazard.
