This course is an introduction into the contemporary debate on the changing patterns of the international economy and challenges the world is facing. The course deals with three major aspects of the global economy, firstly the trans-national economic flows, such as trade in goods and services, migration, financial transactions and investment. The problems are discussed before the background of international micro- and macro-economy. The aspects covered are balance of payments dynamics, exchange rate regimes, national income accounting, terms of trade, etc. Secondly the course deals with the downsides of economic globalisation such as the underlying reasons for crises and their effects on the economy, poverty and environmental degradation. Thirdly the course looks at the actors in the global economy: international organizations, national governments, non-governmental organisations, multinational corporations and regional integration initiatives. Hereby the motives, interest and interaction of the actors is scrutinised and furthermore the development of the global economic governance system is discussed.
