During the recent sales of UMTS licenses in Europe some countries used auctions while others resorted to so-called Beauty Contests. There seems to be a wide consensus among economists that in these and other contexts like privatisation an auction is the better selling mechanism. However, why...

This paper shows that the possibility of collusion between an agent and a supervisor imposes no restrictions on the set of implementable social choice functions (SCF) and associated payoff vectors. Any SCF and any payoff profile that are implementable if the supervisor's information was public...

This paper investigates the empirical importance of allowing for multi-dimensional sources of unobserved heterogeneity in auction models with private information. It in turn develops the estimation procedure that recovers the distribution of private information in the presence of two distinct...

This paper proposes a semi-parametric method to uncover the distribution of bidders' private information in the market for highway procurement when unobserved auction heterogeneity is present. I derive sufficient conditions under which the model is identified and show that the estimation...

Treating markets as arenas where relative advantage is contested, this entry explores the emergence and evolution of Western markets for paintings, 1450–1750, in terms of the players, their creative moves to secure gain, and the rules they devised to maintain order. Primary markets for...

Unanimous voting as the fundamental procedural source of political legitimacy grants veto power to each individual. We present an axiomatic characterization of a class of bidding processes to spell out the underlying egalitarian values for collective projects of a productive state. At heart of...

Unanimous voting as the fundamental procedural source of political legitimacy grants veto power to each individual. We present an axiomatic characterization of a class of bidding processes to spell out the underlying egalitarian values for collective projects of a "productive state". At heart of...

Many economic, political and social environments can be described as contests in which agents exert costly efforts while competing over the distribution of a scarce resource. These environments have been studied using Tullock contests, all-pay auctions and rankorder tournaments. This survey...
