This paper investigates the dynamics of product adoption under incomplete information regarding product quality. A revising agent observes a small sample of actions played in the population and also receives a private signal indicating the realized state. Using a simple heuristic, the agent...

We study the robustness of cheap-talk equilibria to infinitesimal private information of the receiver in a model with a binary state-space and state-independent sender-preferences. We show that the sender-optimal equilibrium is robust if and only if this equilibrium either reveals no information...

Consider a nite, normal form game G in which each player position is occupied by a population of N individuals, and the payoff to any given individual is the expected payoff from playing against a group drawn at random from the other positions. Assume that individuals adjust their behavior...

In [1], it was shown that in games of perfect information, common knowledge of rationality entails that the backward induction outcome is reached, and is consistent (for short, entails BI). That work has been criticized because it assumes that a player chooses rationally at all his nodes, even...

Define a continuous game to be one in which every player's strategy set is a Polish space, and the payoff function of each player is bounded and continuous. We prove that in this class of games the process of sequentially eliminating "never-best-reply" strategies does not terminate after the...

Define a continuous game to be one in which every player's strategy set is a Polish space, and the payoff function of each player is bounded and continuous. We prove that in this class of games the process of sequentially eliminating "never-best-reply" strategies terminates before or at the...
