Combinatorial Clock Auctions (CCAs) have recently been used around the world to allocate spectrum for mobile telecom licenses. CCAs are claimed to significantly reduce the scope for gaming or strategic bidding. This paper shows, however, that CCAs facilitate strategic bidding. Real bidders in...

We analyze the effects of mergers in first-price sealed-bid auctions on bidders' equilibrium bidding functions and on revenue. We also study the incentives of bidders to merge given the private information they have. We develop two models, depending on how after-merger valuations are created. In...

There is by now a large literature arguing that auctions with a variety of after-market interactions may not yield an efficient allocation of the objects for sale, especially when the bidders impose strong negative externalities upon each other. This paper argues that these inefficiencies can be...

We analyze the reporting strategies of firms and the investigation strategies of auditors in an archetype principles-based financial reporting system. To this end, we add a verification stage to a standard cheap-talk game, and apply the resulting game to financial reporting. We show that for a...

We investigate the nature of market failure in a dynamic version of Akerlof (1970) where identical cohorts of a durable good enter the market over time. In the dynamic model, equilibria with qualitatively different properties emerge. Typically, in equilibria of the dynamic model, sellers with...

This paper considers a government auctioning off multiple licenses to firms who compete in a market after the auction. Firms have different costs, and cost efficiency is private information at the auction stage and the market competition stage. If only one license is auctioned, standard results...

We consider a government auctioning off multiple licences to firms that compete in an aftermarket. Firms have different costs, and cost-efficiency is private information in the auction and in the aftermarket. If only one licence is auctioned, standard results say that the most efficient firm...
