Using microeconomics and game theory mainly, the public choice explains political phenomena, analyzes interdependence between polity and economy, and clarifies the basis of legal system and social norm. Adopting the analytical methods of microeconomics and game theory here means that the public choice basically depends on the hypothesis that people and organizations behave to maximally achieve their specific objectives under given conditions.
In this lecture, in order to place emphasis on having students understand the basic idea of public choice, we will not carry out detailed technical explanation as a rule. However, because it is necessary to respond well to the intellectual requirements of graduate students, somewhat advanced contents may be included for undergraduates.
