Essays On Repeated Games And Double Auctions

The alternating double auction market institution is presented as a discrete time version of the open outcry market. The game in extensive form is analyzed in an almost perfect information setting, using the concept of subgame perfectness. By applying two new equilibrium selection criteria, a general existence result is obtained for "impatience equilibria" of the game. All such equilibria are shown to have unique properties concerning the traded quantities and prices. The most important results are that the equilibrium prices are independent of the number of traders and are always very close to - if not inside - the range of competitive prices. The latter can be evaluated as game theoretic support for the convergence of prices to the competitive price. The process of price formation is traced by applying the learning direction theory and introducing the "anchor price hypothesis".

This second Cambridge University Press collection of papers by Vernon L. Smith, a creator of the field of experimental economics, includes many of his primary authored and coauthored contributions on bargaining and market behavior between 1990 and 1998. The essays explore the use of laboratory experiments to test propositions derived from economics and game theory. They also investigate the relationship between experimental economics and psychology, particularly the field of evolutionary psychology, using the latter to broaden the perspective in which experimental results are interpreted. The volume complements Professor Smith's earlier work by demonstrating the importance of institutional features of markets in understanding behavior and market performance. Specific themes investigated include rational choice, the notion of fairness, game theory and extensive form experimental interactions, institutions and market behavior, and the study of laboratory stock markets.

Personalized and continuing relationships play a central role in any society. Economists have built upon the theories of repeated games and reputations to make important advances in understanding such relationships. Repeated Games and Reputations begins with a careful development of the fundamental concepts in these theories, including the notions of a repeated game, strategy, and equilibrium. Mailath and Samuelson then present the classic folk theorem and reputation results for games of perfect and imperfect public monitoring, with the benefit of the modern analytical tools of decomposability and self-generation. They also present more recent developments, including results beyond folk theorems and recent work in games of private monitoring and alternative approaches to reputations. Repeated Games and Reputations synthesizes and unifies the vast body of work in this area, bringing the reader to the research frontier. Detailed arguments and proofs are given throughout, interwoven with examples, discussions of how the theory is to be used in the study of relationships, and economic applications. The book will be useful to those doing basic research in the theory of repeated games and reputations as well as those using these tools in more applied research.
