We analyze a settlement and litigation game in which both parties possess private information relevant to the value of a claim. The plaintiff knows the level of damages, while the defendant knows the probability he will be held liable for those damages. We consider two alternatives: (1) the...

We examine an evolutionary model in which the primary source of "noise" that moves the model between equilibria is not random, arbitrarily improbable mutations but mistakes in learning. We find conditions under which the payoff-dominant equilibrium in a 2 x 2 game is selected by the model as...

This paper looks at simple games with one round of pre-play communication followed by a simultaneous move, complete information game. In these games the {\em curb} concept distinguishes among efficient equilibria according to their risk. The paper contains two major results. First, if only one...

Standard non-cooperative game theory is not selective enough to discriminate among many of the possible outcomes in infinitely repeated reciprocity games. However, experimental evidence, especially in symmetric games, suggests strongly that people arrive at only a few outcomes. Theoretical...

Two of the most important refinements of the Nash equilibrium concept for extensive form games with perfect recall are Selten's (1975) {\it perfect equilibrium\/} and Kreps and Wilson's (1982) more inclusive {\it sequential equilibrium\/}. These two equilibrium refinements are motivated in very...

An intuitively natural consistency condition for contingent plans is necessary and sufficient for a contingent plan to be rationalized by maximization of conditional expected utility. One alternative theory of choice under uncertainty, the weighted-utility theory developed by Chew Soo Hong...

I continue the study, begun in Blume (1993), of stochastic strategy revision processes in large player populations where the range of interaction between players is small. Each player interacts directly with only a finite set of neighbors, but any two players indirectly interact through a finite...

We present a new methodology for studying the problem of labor contracting within a firm's boundaries where contracts provide only a minimal commitment to wages and employment. Given the peculiar contractual incompleteness of labor contracts, the resulting wages and profits under an interesting...

We provide an overview of the methods of analysis and results obtained, and, most important, an assessment of the success of rational learning dynamics in tying down limit beliefs and limit behavior. We illustrate the features common to rational or Bayesian learning in single agent, game...

Reciprocity norm in the U.S. Congress and state assemblies has been studied extensively. By contrast, obedience norms frequently observed in many legislative bodies outside the United States have received relatively little attention. We seek to provide an evolutionary account of obedience norms....
