One of the most frequently used words is "strategy". However, there are cases in which people who are not understanding even from the distinction between strategy and tactics make influential remarks in public places. This course aims to understand the essence of strategic decision making that appears in various fields and to acquire basic ideas useful for problem finding and solving in each area of interest of each student. In addition, we would like to have some useful hints on how to design a system that is preferable from a social point of view in some sense (although it is also a subject of consideration) against such entities that make strategic decision making.
Based on these problem consciousness, we learn the essence of noncooperative game theory which can be applied to each case of individual field such as economy, business, political process, international relations, etc., and also briefly touch on some results of recent experimental economics. In addition, considering why it is difficult to realize desirable policies from a viewpoint of public choice theory, we will examine the theoretical basis on which we make normative judgment with reference to Amartya Sen's normative economics.
