Short course

Optimal transport and economic applications

PSE summer school, June 22-26, 2020


This short course is focused on optimal transport theory and matching models and their applications to economics, in various fields such as labor markets, economics of marriage, industrial organization, matching platforms, networks, and international trade. It will provide the crossed perspectives of theory, empirics and computation. A particular emphasis will be given on computation (R and Python). This course is partly based on Galichon’s 2016 monograph, Optimal Transport Methods in Economics. Princeton University Press.


Wednesday, June 24, 9am-12:30pm
Thursday, June 25, 9am-12:30pm
Friday, June 26, 9am-11am
