Collective Choice Theory

The course Collective Choice Theory focuses on the application of economics to political science. In particular, we will apply different economic methodology such as rational choice and game theory to the study of systems and institutions for making collective choices. For this purpose we will introduce various methods of aggregating preferences of members of a given society into some social or collective preference. In-depth attention will be given to areas such as decision making in committees, legislative bargaining, design of elections and the analysis of voting power.

The course is taught in English and lectures and exercise classes alternate loosely (20 units in total). The exam will be posed in English (questions can, however, be answered in either English or German). If less than 5 participants register for a written exam, an oral examination may be held instead of the written exam.
