The course is aimed at providing students that did not take International Economics in the First-cycle degree/Bachelor with some basic theoretical tools. In the part of the course devoted to international trade the focus is on what are the reasons explaining trade patterns among countries and what are the gains from trade. The most important instruments of trade policy are analyzed, and the costs and benefits of protectionist trade policies are assessed. Moreover, multinational enterprises organizational and production choices are explained, in order to understand their functioning. In the part of the course devoted to international monetary economics, the focus is on the mechanisms that determine the exchange rate between currencies, and on the relationship between exchange rates, money supply and interest rates
