It is common to model costs of carrying out strategies in games in relation to the complexity, in some sense, of the strategies. We show a particularly general definition of complexity for this purpose, one that subsumes many alternatives as special cases. We explore how this definition can be...

A person is said to be `trust responsive` if she fulfils trust because she believes the truster trusts her. The experiment we report was designed to test for trust responsiveness and its robustness across payoff structures, and to disentangle it from other possible factors making for...

Game harmony is a generic game property that describes how harmonious (non-conflictual) or disharmonious (conflictual) the interests of players are, as embodied in the payoffs. It can be used to predict cooperation in two-player games. We show how, for large enough positive harmony...

A corrupt transaction is often the result of bargaining between the parties involved.  This paper models bribery as a double auction where a private citizen and a public official strategically interact as the potential buyer and the potential seller of a corrupt service.  Individuals differ in...

This paper discusses the incentive to bundle when consumer valuations are non-additive and/or when products are supplied by separate sellers.  Whether integrated or separate, a firm has an incentive to introduce a bundle discount when demand for the bundle is more elastic than the overall...

We study the implications of conformism among analysts in a CARA Gaussian model of the market for a risky asset, where a trader's information is a message sent by an analyst.  Conformism increases the weight of the public information in the messages, decreasing their informativeness.  More...

The size of adverse selection and moral hazard effects in health insurance markets has important policy implications.  For example, if adverse selection effects are small while moral hazard effects are large, conventional remedies for inefficiencies created by adverse selection (e.g., mandatory...

We show that introducing an external capital market with information asymmetry into a product market model reduces opportunistic substitution of sub-standard goods and encourages producers to concentrate on long-run reputation building.  We test this result with a laboratory experiment.  We...

This paper uses a vertical relational contract between two firms to explore the implications of trade credit when the ability to repay is not observed by the supplier.  Trade credit limits the supplier's possibilities to punish the cashless downstream firms and termination may be used in...

This paper studies uniqueness of equilibrium in symmetric 2 x 2 bayesian games.  It shows that if signals are highly but not perfectly dependent then players play their risk-dominant actions for all but a vanishing set of signal realizations.  In contrast to the global games literature, noise...
