cemmap is happy to annouce a masterclass on Empirical Models of Comparative Advantage and the Gains from Trade by Dave Donaldson.
Starting with a presentation of standard models of comparative advantage that have been used to explain the pattern of trade (who trades what with whom) and the normative effects of trade (who gains and who loses when trade becomes easier to do) both between and within nations. This will span the perfectly competitive models of Ricardo and Heckscher-Ohlin (including their modern versions such as that due to Eaton and Kortum), as well as the monopolistically competitive models of Krugman and Melitz.
