Spectrum auctions are used by governments to assign and price licenses for wireless communications. Effective auction design recognizes the importance of competition, not only in the auction, but in the downstream market for wireless communications. This paper examines several instruments...

We consider a model of oligopolistic firms that have private information about their cost structure. Prior to competing in the market a competitive advantage, i.e., a cost reducing technology, is allocated to a subset of the firms by means of a multi-object auction. After the auction either all...

We consider innovation contests for the procurement of an innovation under moral hazard and adverse selection. Innovators have private information about their abilities, and choose unobservable effort in order to produce innovations of random quality. Innovation quality is not contractible. We...

This paper examines experimentally the effect of a different payment mechanism in the case of a tie on an agent's willingness to pay (WTP) in a winner-take-all contest. We examine how a small chance to pay tax in case of a tie affects the contest's bids. Our hypothesis is that the tax payment is...

This paper examines the effects of spectrum auctions on mobile market competition. A simple theoretical model suggests that bigger incumbents will acquire more spectrum in auction to pre-empt after-market competitors. We use novel data from European 4G spectrum auctions to present suggestive...

In this paper, we analyse a multistage game of competition among auctioneers. In a first stage, auctioneers commit to some publicly announced reserve prices, and in a second stage, bidders choose to participate in one of the auctions. We prove existence of Nash equilibria in mixed strategies for...

We study the effects of corruption on equilibrium competition and social welfare in a first-price public procurement auction. In our model, firms are invited into the auction at positive costs, and a bureaucrat runs the auction on behalf of a government, who may request a bribe from the winning...

We consider contestants who must choose exactly one contest, out of several, to participate in. We show that when the contest technology is of a certain type, or when the number of contestants is large, a self-allocation equilibrium, i.e., one where no contestant would wish to change his choice...

We analyze a divisible good uniform-price auction that features two groups each with a finite number of identical bidders. Equilibrium is unique, and the relative market power of a group increases with the precision of its private information but declines with its transaction costs. In line with...
