Game Theory (ECON 159)Uploaded 20-11-08In business or personal relationships, promises and threats of good and bad behavior tomorrow may provide good incentives for good behavior today, but, to work, these promises and threats must be credible. In particular, they must come from equilibrium behavior tomorrow, and hence form part of a subgame perfect equilibrium today. We find that the grim strategy forms such an equilibrium provided that we are patient and the game has a high probability of continuing. We discuss what this means for the personal relationships of seniors in the class. Then we discuss less draconian punishments, and find there is a trade off between the severity of punishments and the required probability that relationships will endure. We apply this idea to a moral-hazard problem that arises with outsourcing, and find that the high wage premiums found in foreign sectors of emerging markets may be reduced as these relationships become more stable.00:00 - Chapter 1.

Introduction to Ancient Greek History (CLCV 205)Uploaded 20-11-08In this lecture, Professor Kagan traces the development and the power of the Persian empire. He also shows how the Persian empire and the Greek world eventually came into conflict through a few incidents concerning Ionian Greeks in Asia Minor, which eventually turned into the Persian Wars. Professor Kagan ends this lecture with a description of the events of the battle of Marathon in which the Athenians defeated the Persians.00:00 - Chapter 1.

Game Theory (ECON 159)Uploaded 20-11-08We discuss repeated games, aiming to unpack the intuition that the promise of rewards and the threat of punishment in the future of a relationship can provide incentives for good behavior today. In class, we play prisoners' dilemma twice and three times, but this fails to sustain cooperation. The problem is that, in the last stage, since there is then is future, there is no incentive to cooperate, and hence the incentives unravel from the back. We related this to the real-world problems of a lame duck leader and of maintaining incentives for those close to retirement. But it is possible to sustain good behavior in early stages of some repeated games (even if they are only played a few times) provided the stage games have two or more equilibria to be used as rewards and punishments. This may require us to play bad equilibria tomorrow. We relate this to the trade off between ex ante and ex post efficiency in the law. Finally, we play a game in which the players do not know when the game will end, and we start to consider strategies for this potentially infinitely repeated game.00:00 - Chapter 1.

The Civil War and Reconstruction (HIST 119)Uploaded 21-11-08Professor Blight uses Herman Melville's poem "On the Slain Collegians" to introduce the horrifying slaughter of 1864. The architect of the strategy that would eventually lead to Union victory, but at a staggering human cost, was Ulysses S. Grant, brought East to assume control of all Union armies in 1864. Professor Blight narrates the campaigns of 1864, including the Battles of the Wilderness, Spotsylvania, and Cold Harbor, and the siege of Petersburg. While Robert E. Lee battled Grant to a stalemate in Virginia, however, William Tecumseh Sherman's Union forces took Atlanta before beginning their March to the Sea, destroying Confederate morale and fighting power from the inside. Professor Blight closes his lecture with a description of the first Memorial Day, celebrated by African Americans in Charleston, SC 1865.00:00 - Chapter 1.
