Designed for the serious reader, this book teaches strategy through the use of game theory. The focus is on setting up and solving games, especially those that arise in economics and business. Develops modeling skills as well as the ability to implement a certain format, the form of the game, by using proven applications and examples of setups. Contains an analogous framework of necessary condition (equilibrium) and sufficient conditions such as undominated strategies, symmetry and subgame perfection to motivate solutions. Features a variety of examples ranging from the Bible to Wall Street.
