Preparation

I am not directly examining you on any of the pre-midterm content  however given how the course is organized, a good working knowledge of pre-midterm may be necessary to answer the post- midterm content.

For the pre-midterm: Go through the Keywords/Topics from the le I sent out in connection with preparing for the mid-term earlier in the term,  and make sure you know the basic definitions and the conceptual connections between them. Read through the solutions to the various problem sets — in most cases it is simply a matter of recalling what you already learned for the midterm.

For the post-midterm:  Below is a list of keywords/glossary of terms that you should be hitting upon.   Importantly, work through all the problems from Problem Set 6 onwards by which I mean try to solve the problems on your , see the solutions, then work through the problems on your own again.   Of course, Lectures, Lecture Slides, Quiz 2 and assigned readings are all also important.

Make sure that you have a good understanding of Game Theory part of the course.  In fact a simple check of how well you are prepared  is how well you understand  Repeated Games/Extensive form games (Lec 12) and Lec 13.  That is a good indication of your preparation for the course since those lectures depend on everything that you was done in the prior parts of the course.

Keywords/Topics - Post Midterm

(Check out the midterm-prep advice that I sent out prior to midterm exam for pre-midterm material)

1. Production and Comparative Statics —  see Lec 6 slides, Quiz 2 questions. You should know how to apply  Envelope theorem, use comparative statics propositions/theorems.

2. Expected Utility Hypothesis Objective vs Subjective beliefs and modeling choice under risk vs. uncertainty.    Indifference curves under expected utility Money lotteries. Attitudes to risk, risk aversion and the shape of the vNM utility function. certainty equivalent and risk.  Arrow-Pratt Measure of Risk Aversion, Demand for insurance.

3.  Strategic Form games:  Modeling them,  IEDS, Nash Equilibrium. Mixed Strategies and Nash Equilibria in Mixed Strategies.  You should know how to characterize Nash equilibria  The problem sets from Problem Set 7 covers a number of scenarios.

4. Extensive form games: Modeling them. The key concept of a strategy in an extensive form game as contingent plan of action. Reduction of an extensive form game to an equivalent strategic form game. Perfect information vs. Imperfect information in a game.

Solving nite extensive form games of perfect information via backward induction. Concept of a sub-game and Subgame  perfect equilibrium (SPE)

5. Extensive from bargaining games:  (Rubinstein's) alternating offers bargaining game without deadline, role of patience (i.e. 6) in determining bargaining shares in SPE. The “first mover advantage” in such games.

6. Repeated Games: calculate the payoff of a play of a G1 . Use that to verify Nash equilibria or SPE. Tacit Collusion and other such economic applications (see Jonathan Levin's lecture note given in Lec 12 slides)

Minimax payos, Folk Theorem

7. Games of Incomplete information: Harsanyi Doctrine, Understand well the concept of a “type” and strategy” and Bayes Nash Equilibrium.

Basic Auctions as games of Incomplete Information. The concept of “Payoff/Revenue Equiv- alence” and  Virtual Valuations” .     Using Virtual Valuations”   to characterize Revenue Maximizing Auction formats.

Ex-post Efficiency & VCG mechanism.  Impossibility of ex-post efficient Trade (the Myerson- Satterthwaite theorem).
