Standard models of observational learning in settings of sequential choice have two key features. The first is that players make decisions by using Bayes' rule to update their beliefs about payoffs from a common prior. The second is that each agent's decision rule is common knowledge, so that...

We analyze a market game where traders are heterogeneous with respect to their rationality level and have asymmetric information. The market mechanism results into a statistical equilibrium, where traders randomise among their available actions due to their limited rationality. We provide a...

The interaction between a sophisticated player and a fictitious player is analyzed and applied to the problem of optimal enforcement. An adaptive potential offender myopically responds to the history of past enforcement. How can a sophisticated enforcement official take advantage of this...

We introduce negative externalities in the form of ill will among the players of the classic two-sided assignment game of Shapley and Shubik, by letting each player's utility be negatively correlated with the payoff of all the players in his group. The new game is very complex, but under a...

In this paper we analyze the value of the information in a cooperative model. There is an agent (the innovator), having relevant information which can be sold to some potential buyers. The n potential users of the information share a market. The expected utility of each of them can be improved...

The paper analyses the timing of spontaneous environmental innovation when second-mover advantages, arising from the expectation of declining investment costs, increase the option value of waiting created by investment irreversibility and uncertainty about private payoffs. We then focus on the...

We consider a non-cooperative three-stage game played by two regulator-firm hierarchies. We suppose that raising public funds is socially costly and that market sizes are large enough. Contrary to what might be expected, we show that opening markets to international trade increases the per-unit...

We introduce a modified version of the Ultimatum game where people bargain over losses instead of gains. Results show that when people bargain over losses, they make more aggressive offers, in terms of their own monetary well-being, as compared to when they bargained over gains.

This paper evaluates the discrete bid first-price sealed-bid (FPSB) auction in a model with a general value distribution. We show that a symmetric Bayesian Nash equilibrium exists for the discrete bid FPSB auction. We further prove that the discrete bid FPSB equilibrium conditionally converges...
