This article investigates rationalizable implementation in social environments where agents can provide hard evidence on the private information they possess. Specifically, we study necessary and sufficient conditions for virtual implementation using a notion of Rationalizability that captures...

In this paper, we analyze the consequences of taking noise into account in a simple two person fishery management game. Both a stochastic and deterministic formulation are considered. Compared to the noise-free model it is shown that the used stochastic framework has no implications for the...

Suppose that the goals of a society can be summarized in a social choice rule, i.e., a mapping from relevant underlying parameters to final outcomes. Typically, the underlying parameters (e.g., individual preferences) are private information to the agents in society. The implementation problem...

We study dominant strategy implementation especially in economic environments. We first showthat in general environments, strategy-proofness and quasi-strong-non-bossiness together are necessary and sufficient for dominant strategy implementation via the associated direct revelationmechanism. We...

In this paper, we study full implementation problem by mechanisms that allow delay. The delay on the equilibrium path may be zero, infinitesimally small or a fixed positive number. In all these three cases, implementable rules are characterized by a monotonicity-like condition alone, including...

We consider the allocation problem of infinitely divisible resources with at least three agents. For this problem, Thomson (Games and Economic Behavior, 52: 186-200, 2005) and Dogan (Games and Economic Behavior, 98: 165-171, 2016) propose "simple" but not "procedurally fair" game forms which...

We know from Gale and Shapley (1962) that every Two-Sided Matching Game has a stable solution. It is also well-known that the number of stable matchings increases with the number of agents on both sides. In this paper, we propose two mechanisms, one of which is a variant of the other, to the...

Strategy-proofness, requiring that truth-telling be a dominant strategy, is a standard concept in social choice theory. However, this concept has serious drawbacks. In particular, many strategy-proof mechanisms have multiple Nash equilibria, some of which produce the wrong outcome. A possible...

We show that Ergin & Sönmez's (2006) results which show that for schools it is a dominant strategy to truthfully rank the students under the Boston mechanism, and that the Nash equilibrium outcomes in undominated strategies of the induced game are stable, rely crucially on two assumptions....

We consider the implementation problem under incomplete information and private values. We investigate double implementability of social choice functions in dominant strategy equilibria and ex post equilibria. We show that the notion of an ex post equilibrium is weaker than the notion of a...
