Is it possible to analyze a wide variety of social and economic problems using a unified framework? In the first module, we address this question. We will see that the concept of rational decision making is useful, but it is not quite sufficient to provide governing principles. Motivated examples and some history of game theory will be provided. You will also be asked to play a simple card game to see how it feels to make your decisions strategically.

The basic solution concept of game theory is Nash equilibrium. In Module 2, we try to understand this central concept through various examples and ask the following crucial question: how do players come to play a Nash equilibrium?

In Module 3, we will dig deeper into the relationship between rationality and Nash equilibrium. We will consider the whole spectrum of possible intellectual capacities of players, spanning the range from unlimited ability for sophisticated reasoning to absolute zero intelligence. In the end, you will see that Nash equilibrium can emerge under a fairly wide range of intellectual capacities of players.
