Noting that a full characterization of Nash-implementation is given using a canonical-mechanism and Maskin's theorem (Maskin, 1999) is shown using a mechanism with Saijo's type of strategy space reduction (Saijo, 1988), this paper fully characterizes the class of Nash-implementable social choice...

In their recent work Thomas S. Schelling, reiterating original arguments about game theory and its applications to social sciences. In particular, game theory helps to explore situations in which agents make decisions interdependent (strategic communication). Schelling's originality is to extend...

We compare communication about private information to communication about actions in a one-shot 2-person public good game with private information.The informed player, who knows the exact return from contributing and whose contribution is unobserved, can send a message about the return or her...

We consider a model of oligopolistic firms that have private information about their cost structure. Prior to competing in the market a competitive advantage, i.e., a cost reducing technology, is allocated to a subset of the firms by means of a multi-object auction. After the auction either all...

Implementation in iteratively undominated strategies relies on permissive conditions. However, for the sufficiency results available, authors have relied on assumptions that amount to quasilinear preferences on a numeraire. We uncover a new necessary condition that implies that such assumptions...

We model a game similar to the interaction between an academic advisor and advisee. Like the classic cheap talk setup, an informed player sends information to an uninformed receiver who is to take an action which affects the payoffs of both sender and receiver. However, unlike the classic cheap...

We study coordination failures in many simultaneously occurring coordination problems called projects. Players encounter one of these projects, but have an outside option to search for another of the projects. Drawing on the global games approach, we show that such a mobile game has a unique...

This paper investigates face-to-face lying and beliefs associated with it. In experiments in Sweden and Japan, subjects answer questions about personal characteristics, play a face-to-face sender-receiver game and participate in an elicitation of lie-detection beliefs. The previous finding of...

We consider a random-matching model in which every agent has a categorization (partition) of his potential opponents. In equilibrium, the strategy of each player is a best response to the distribution of actions of his opponents in each category of his categorization. We provide equivalence...

Networks can have an important effect on economic outcomes. Given the complexity of many of these networks, agents will generally not know their structure. We study the sensitivity of game-theoretic predictions to the specification of players' (common) prior on the network in a setting where...
