Experimentalists frequently claim that human subjects playing games in the laboratory violate such solution concepts as Nash equilibrium and subgame perfection. This claim is premature. What has been rejected are certain joint hypotheses about preferences, knowledge, and behavior. This note...

Saez-Marti and Weibull [4] investigate the consequences of letting some agents play a myopic best reply to the myopic best reply in Young's [8] bargaining model. This is how they introduce ''cleverness'' of players. We analyze such clever agents in general finite two-player games. We show that...

We consider Bayesian incentive compatible and individually rational mechanisms for resolving conflicts between two agents who are uncertain about each other's fighting potential. We model the default option of outright conflict as a probabilistic contest. Examples of such contests may be...

The generalised entropy measure is applied to decompose overall income inequality over several years into one part showing inequality of long-run (permanent) income and one part showing variability of single individuals' incomes over time. By comparing these components of inequality for pre- and...

A product set of pure strategies is a prep set ("prep" is short for "preparation") if it contains at least one best reply to any consistent belief that a player may have about the strategic behavior of his opponents. Minimal prep sets are shown to exists in a class of strategic games satisfying...

Game theory is usually difficult to test precisely in the field because predictions typically depend sensitively on features that are not controlled or observed. We conduct one such test using field data from the Swedish lowest unique positive integer (LUPI) game. In the LUPI game, players pick...

We study costless pre-play communication of intentions among inexperienced players. Using the level-k model of strategic thinking to describe players' beliefs, we fully characterize the effects of pre-play communication in symmetric 2×2 games. One-way communication weakly increases coordination...

Two principals simultaneously appoint one agent each and decide how much power to give to their agents. The agents' task is to bargain over the provision of a public good. Power here means the right to decide the own side's provision if negotiations break down. In equilibrium the principals...

In the present work, I adopt the cognitive hierarchy approach to analyze the centipede game. To this end, I present and study an extensive-form version of Camerer et al.'s (2004) original normal-form model. The resulting predictions are evaluated empirically using laboratory data borrowed from a...

This paper extends the concept of weak renegotiation-proof equilibrium (WRP) to allow for costly renegotiation and shows that even small renegotiation costs can have dramatic effects on the set of equilibria. More specifically, the paper analyzes the infinitely repeated Bertrand game. It is...
