040842 VO International Trade (BA) (2020S)

We will discuss the most important workhorse models of international trade, such as the Armingotn model (and the gravity equation), Ricardian model (country-sector productivity differences), the Heckscher-Ohlin model (international differences in factor endowments), the Krugman model of intra-industry trade (increasing returns and imperfect competition) and the Melitz model (firm heterogeneity). We will also cover topics on multinationals, trade policy and economic geography.
