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.


A) Traditional theories of international trade

The general traditional model of international trade. Overview. The general traditional model: assumptions; autarkic equilibrium; free-trade equilibrium; gains from trade in consumption and production; the direction of trade; the excess demand curve (net imports). [Slides]

The Ricardian model of international trade. The concept of opportunity-cost. The Ricardian model of trade: assumptions: the linear production possibility frontier; definition of autarkic equilibrium; the free-trade equilibrium; the excess demand curve in the Ricardian model; gains from trade. [Slides]

The Heckscher-Ohlin model of international trade. Overview. The model: assumptions; production in a small open economy; factor prices and commodity prices; the Stolper-Samuelson theorem; international equilbrium; integrated equilibrium; the theorem of equalization of factors prices; the Rybczynski theorem; the Heckscher-Ohlin theorem; international trade and income distribution. [Slides]
