82181 - INDUSTRIAL ECONOMICS AND INTERNATIONAL TRADE

Conoscenze e abilità da conseguire

The aim of the course is to introduce the student to the main concepts of industrial organisation in the context of open economies. First, the course analyses the interaction of firms in the market focusing on their strategic behaviour and on how the latter is affected by competition policy. Second, the course introduces the models of international trade to illustrate how international competition affects firms and country behaviour and its impact on economic growth. At the end of the course students are able to: (a) understand strategic interaction of firms; (b) evaluate the role of competition policy; (c) understand how international trade fosters economic growth.
