focusing on examples from economics and business. For example, we will examine competition in oligopolistic markets and will analyse likely (and unlikely) outcomes of such competition. In this course we will focus on decision making in economic and business settings, but the ideas of game theory can be applied to almost every situation and are widely used by e.g. psychologists, in political sciences, but also in the natural sciences such as biology. A game in this context is a strategic interaction of players, e.g. competitors deciding about prices.
