A competition authority has an objective, which specifies what output profile firms need to produce as a function of production costs. These costs change over time and are only known by the firms. The objective is implementable if inequilibrium, the firms cannot collude on their reports to the...

This paper analyzes the ability of group members to cooperate in rent-seeking in a context of between-group competition. For this purpose, we develop an infinitely repeated rent-seeking model with two groups where within-group cooperation is supported through the use of a double-edged trigger...

At each moment in time, some alternative from a finite set is selected by a dynamic process. Players observe the alternative selected and sequentially cast a yes or a no vote. If the set of players casting a yes-vote is decisive for the alternative in question, the alternative is accepted and...

We analyze dynamic electoral competition policy changes. The costs of changing a policy increase with the extent of the shift and generate an incumbency advantage. We characterize the dynamics of Markov equilibria in terms of history and party polarization, and analyze how policies are...

In this paper, we reexamine Eliaz's results (2002) of fault tolerant implementation on one hand and we extend theorems 1 and 2 of Doghmi and Ziad (2008 a) to bounded rationality environments, on the other. We identify weak versions of the k-no veto power condition, in conjunction with unanimity...

A high court has to decide whether a lawis constitutional, unconstitutional, or interpretable. The voting system is runoff. Runoff voting systems can be interpreted both, as social choice functions or as mechanisms. It is known that, for universal domains of preferences, runoff voting systems...

Using data from an experiment by Forsythe, Myerson, Rietz, and Weber (1993), designed for a different purpose, we test the "standard theory" that players have preferences only over their own mentary payoffs and that play will be in (evolutionary stable) equilibrium. In the experiment each...

We study Nash implementation by natural price-quantity mechanisms in pure exchange economies with free-disposal (Saijo et al., 1996, 1999) where agents have weak/strong intrinsic preferences for honesty (Dutta and Sen, 2012). Firstly, the Walrasian rule is shown to be non-implementable where all...

This paper studies implementation problems in the wake of a recent trend of implementation of non-consequentialist nature, which draws on the evidence taken from experimental and behavioral economics. Specifically, following the seminal works by Matsushima (2008) and Dutta and Sen (2009), the...

This paper studies full implementation problems in (pure and mixed) Nash equilibrium in finite environments. We restrict the designer to adopt<I>finite</I> mechanisms, thus ruling out integer games. We provide a condition, top-<I>D</I> inclusiveness, that together with set-monotonicity is sufficient for mixed...</i></i>
