We consider two mechanisms to procure differentiated goods: a request for quote and an English auction with bidding credits. In the request for quote, each seller submits a price and the inherent quality of his good. Then the buyer selects the seller who offers the greatest difference in quality...

This paper formulates a model of dynamic, endogenous reform of political institutions. Specifically, a class of dynamic political games (DPGs) is introduced in which institutional choice is both recursive and instrumental. It is recursive because future political institutions are decided under...

We study a model of civil dispute with delegation in which a plaintiff's lawyer works on a contingent fee basis but a defendant's lawyer on an hourly fee basis. We first derive the conditions under which delegation to the lawyers brings both the plaintiff and defendant more payoffs, compared to...

In its standard “public choice” form, the mechanism-design framework abstracts from institutional and technological constraints beyond those that the modeler can represent in the definition of states, outcomes, and preferences. This abstraction can create a useful simplification. However,...

We conduct an event analysis on OPEC quota announcements to determine their impact on the stock returns in the oil industry. We find that announcements to reduce the quota are followed by positive excess returns over pre-announcement levels, announcements of no action are met with negative...

We investigate the implications of two properties, sustainability and exemption, when imposed separately in conjunction with other basic properties for the resolution of conflicting claims. Under the protective properties, agents with sufficiently small claims in relation to the others are fully...

We give necessary and sufficient conditions for the existence of symmetric equilibrium without ties in common values auctions, with multidimensional independent types and no monotonic assumptions. When the conditions are not satisfied, we are still able to prove the existence of pure strategy...

In this paper we characterize the optimal allocation mechanism for $N$ objects, (permits), to $I$ potential buyers, (firms). Firms' payoffs depend on their costs, the costs of competitors and on the final allocation of the permits, allowing for externalities, substitutabilities and...
