Abstract: We consider auctions as games and we discuss how to analyze such games, and providing robust guarantees for their performance even when players participate in multiple  auctions, have valuations that are complex functions of multiple outcomes, and are using learning strategies to deal with an uncertain environment.

2.30pm:  Invited Talk by Dirk Bergemann. The Limits of Price Discrimination

Abstract: We analyze the welfare consequences of a monopolist having additional information about consumers’ tastes, beyond the prior distribution; the additional information can be used to charge different prices to different segments of the market, i.e., carry out “third degree price discrimination”. We show that the segmentation and pricing induced by the additional information can achieve every combination of consumer and producer surplus such that: (i) consumer surplus is non-negative, (ii) producer surplus is at least as high as profits under the uniform monopoly price, and (iii) total surplus does not exceed the efficient gains from trade. As well as characterizing the welfare impact of price discrimination, we examine the limits of how prices and quantities can change under price discrimination. We also examine the limits of price discrimination in richer environments with quantitydiscrimination and limited ability to segment the market.

9.30am:  Invited Talk by Joe Halpern.  Language-based Games.

Abstract: We introduce language-based games, a generalization of psychological games that can also capture reference-dependent preferences. In language-based games, the domain of the utility function is extended to what we call situations: maximal sets of atisfiable formulas in some language. The role of the underlying language in this framework is thus particularly critical. By choosing the right language, we can capture psychological games [Geanakpolos, Pearce, and Stachetti] and reference-dependent preference [Koszegi and Rabin]. Of special interest are languages that can express only coarse beliefs (e.g., the probability of an event is “high” or “low”, rather than “the probability is .628”. Despite the expressive power of the approach, we show that it can describe games in a simple, natural way. Nash equilibrium and rationalizability are generalized to this setting; Nash equilibrium is shown not to exist in general, while the existence of rationalizable strategies is proved under mild conditions.

This represents joint work with Adam Bjorndahl and Rafael Pass.

2.30pm:  Invited Talk by Ehud Kalai.  Learning and Stability in Large Games

Abstract: The sensitivity of Nash equilibrium to modeling details of a game makes its predictions unreliable in many applications. In games with many players, however, Nash equilibria are robust and the modeling difficulties are less severe. Using a new concept of compressed Nash equilibrium, we discuss these properties in a general model that includes uncertainties about unknown fundamentals of nature and players’ types. Despite the failing of robustness in short interaction, aftersufficiently long play robustness is obtained.

Motivating examples include games played on the web and price stability in market games.
