The single crossing property plays a crucial role in monotone comparative statics (Milgrom and Shannon (1994)), yet in some important applications the property cannot be directly assumed or easily derived.  Difficulties often arise because the property cannot be aggregated: the sum of two...

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...

Ultimatum games have been extensively used in experimental studies. By studying the consequences that restrictions shared by ultimatum games have in subject`s behaviour, this paper argues that some results are falsified by design constraints. This paper also presets a taxonomy of certification,...

Through an experiment this study investigates the effects that verification has on honest traders. This paper demonstrates that by reducing the scope for trust verification can have a negative effect on the behaviour of honest individuals. Specifically, the analysis shows that trustworthy agents...

This paper shows that a monopolistic certifying party can have incentives to disclose revealing information about the agent he is certifying. Using a three-person game-theoretic model and allowing certificate users (buyers) to have noisy estimates of the quality level of the agent being...

The standard model of an extensive form game rules out an important phenomenon in situations of strategic interaction: deception. Using examples from the world of ancient Greece and from modern-day Wall Street, we show how the model can be generalized to incorporate this phenomenon. Deception...

We analyze the incentives to disclose intermediate research results. We find that despite the help that disclosure can give to a rival, the leading innovator sometimes chooses to disclose. Disclosure signals commitment to the research project, which may induce a rival to exit. With weak product...

This paper shows that a monopolistic certifying party can have incentives to disclose revealing information about the agent he is certifying. Using a three-person game-theoretic model and allowing certificate users (buyers) to have noisy estimates of the quality level of the agent being...

We study a model of informed principal with private values where the principal is risk neutral and the agent is risk averse. We show that the principal, regardless of her type, gains by not revealing her type to the agent through the contract offer. The equilibrium allocation transfers some...

We construct a dynamic epistemic model for extensive form games, which generates a hierarchy of beliefs for each player over her opponents` strategies and beliefs, and tells us how those beliefs will be revised as the game proceeds. We use the model to analyze the implications of the assumption...
