Game theory provides a scientific approach to the study of social interactions which focusses on the strategic aspects of decision-making between two or more individuals or groups. This course will cover the basic elements of game theory and a light introduction to political economy. The aim of the course is to provide a deeper understanding of game theoretic tools and to help you understand how these ideas have been developed and applied in the political science literature. The first part of the course will look at static games where all players move simultaneously and the second part of the course will look at dynamic games players move in sequence. In each part we will start with a simple setting where all information is known to all players (complete information) and we will then move to more complex setting where some information is not known to all players (incomplete information).
