Game Theory (ECON 159)

We first discuss Zermelo's theorem: that games like tic-tac-toe or chess have a solution. That is, either there is a way for player 1 to force a win, or there is a way for player 1 to force a tie, or there is a way for player 2 to force a win. The proof is by induction. Then we formally define and informally discuss both perfect information and strategies in such games. This allows us to find Nash equilibria in sequential games. But we find that some Nash equilibria are inconsistent with backward induction. In particular, we discuss an example that involves a threat that is believed in an equilibrium but does not seem credible.

The American Novel Since 1945 (ENGL 291)

In this final lecture on The Human Stain, Professor Hungerford argues that desire is the engine of narrative, for Roth, both at the structural level and in the very grammar of his sentences. Sex and writing are alike in their attempt to cross the boundaries between persons. Passing does not only occur racially, but is also likened to the process whereby a writer, like Roth or his proxy Nathan Zuckerman, comes to inhabit the subjectivities of other characters. One effect of these conflations--for example, Nathan standing for Faunia as he dances with Coleman--is to raise the threat of homoeroticism, which for Roth collapses difference with same-sex desire. Such stereotypes are a controversial characteristic of Roth's fiction, which nevertheless continues to draw great admiration.

Game Theory (ECON 159)

We consider games in which players move sequentially rather than simultaneously, starting with a game involving a borrower and a lender. We analyze the game using "backward induction." The game features moral hazard: the borrower will not repay a large loan. We discuss possible remedies for this kind of problem. One remedy involves incentive design: writing contracts that give the borrower an incentive to repay. Another involves commitment strategies; in this case providing collateral. We consider other commitment strategies such as burning boats. But the key lesson of the day is the idea of backward induction.

00:00 - Chapter 1. Sequential Games: Backward Induction
17:57 - Chapter 2. Sequential Games: Moral Hazard
29:50 - Chapter 3. Sequential Games: Incentive Design
44:29 - Chapter 4. Sequential Games: Commitment Strategies
01:01:06 - Chapter 5. Sequential Games: Backward Induction Is Really Important
