We study optimal bidder collusion in an independent private value first-price auction with two bidders and two possible valuations. There is a benevolent center that knows the bidders’ valuations and sends private signals to the bidders in order to maximize their expected payoffs. After...

We present a cheap talk extension to any two-player, finite, complete information game, and ask what correlations over actions are implementable in Nash equilibria of the extended game. In the extension, players communicate repeatedly through a detail-free mediator that has been studied in...

The result of Colombo and Labrecciosa [Colombo, Luca and Labrecciosa, Paola (2006). 'The suboptimality of optimal punishments in Cournot supergames', Economics Letters 90, pp. 116-121.] that optimal punishments are inferior to Nash-reversion trigger strategies with decreasing marginal costs is...

The paper presents an endogenous growth economy with a representation of the tax rate system in the Baltic countries. Assuming that government spending is a given fraction of output, the paper shows how a flat tax system balanced between labor and corporate tax rates can be second best optimal....

The existence of ex-ante strong incumbents may constitute a barrier to entry in auctions for goods such as licenses. Favoring the allocation to entrants is a way to induce entry and thus create competition. Designs such as the Anglo-Dutch auction have been proposed with this goal in mind. We...
