EC 490

Week 1

 

1.             Game theory is the science of rational  behavior  in interactive situations. What is meant by ‘interactive’?  That what counts as optimal for each party partly depends on what other parties do. What is meant by rational?  Merely that parties have objectives, and that their actions are selected so as to aim at bringing these objectives about.

 

2.             Parametric choice: trying to optimize in circumstances where all the relevant parameters are independent of your decision. Some parameters might be unknown to you, but none are hiding from you or changing because you’re thinking about them.

Non-parametric choice: some parameters  relevant to your optimizing are interacting with your decision.

 

3.             Major figures in the history of game theory:

Thomas Hobbes (1588 – 1679); basic logic of games

David Hume (1711 – 1776); basic logic of normative coordination

Antoine Cournot (1801-1877); logic of business competition

Joseph Bertrand (1822-1900); logic of business competition

John von Neumann  (1903-1957); mathematics of 2-person zero-sum games; the founder of game theory

John Nash (1928 - ); general concept for solving games

Nobel Prize –winning game theorists: Nash, Reinhardt Selten, John Harsanyi, Thomas Schelling, Robert Aumann
