We experimentally examine the effectiveness of a leniency program against bidding rings in two commonly used auctions: the English auction (EN) and the first-price sealed-bid auction (FPSB). Our results show that the leniency program does not affect the average winning bid, nor the average...

We experimentally examine the collusive properties of two commonly used auctions: the English auction (EN) and the first-price sealed-bid auction (FPSB). In theory, both tacit and overt collusion are always incentive compatible in EN while both can be incentive compatible in FPSB if the auction...

Currently no refinement exists that successfully selects equilibria across a wider range of Cheap Talk games. We propose a generalization of refinements based on credible deviations, such as neologism proofness and announcement proofness. According to our Average Credible Deviation Criterion...

The same contestants often meet repeatedly in contests. Behavior in a contest potentially provides information with regard to one's type and can therefore influence the behavior of the opponents in later contests. This paper shows that if effort is observable, this can induce a ratchet effect in...

Perfectly discriminating contests (or all pay auction) are widely used as a model of situations where individuals devote resources to win some prize. In reality such contests are often preceded by investments of the contestants into their ability to fight in the contest. This paper studies a two...

This paper models the trade-off between production and appropriation in the presence of simultaneous inter- and intra-group conflicts. The model exhibits a 'group cohesion effect': if the contest between the groups becomes more decisive, or contractual incompleteness between groups becomes more...

This paper considers incentives for information acquisition ahead of conflicts. We characterize the (unique) equilibrium of the all-pay auction between two players with one-sided asymmetric information. The type of one player is common knowledge. The type of the other player is drawn from a...

This paper extends the axiomatic characterization of contest success functions of Skaperdas (1996) and Clark and Riis (1998) to contests between groups. – Contest ; conflict ; axiom ; group

Lobbyists choose what to lobby for. If they can precommit to certain policy proposals, their choice will have an influence on the behavior of opposing lobbyists. Hence lobbyists have an incentive to moderate their policy proposals in order to reduce the intensity of the lobbying contest. This...

Trade opportunities are generally seen as valuable instruments to improve the allocation of resources in society. However, when the traded rights are secured through unproductive rent-seeking contests, the tradeability of the rents may provide stronger incentives to invest in rent-seeking...
