In this paper we study a large market in which sellers compete by offering auctions to buyers instead of simple fixed price contracts. Two variants of the model are studied. One extends a model first analyzed by Wolinsky (1988) in which buyers learn their valuations only after meeting sellers....

This paper studies an internet trading mechanism similar to the one described in Peters and Severinov (2000) in a market where traders values are interdependent. Conditions are given for which this mechanism has a perfect Bayesian equilibrium which supports allocations that are the same as the...

Proofs of some of the theorems in <a href=\"http://microeconomics.ca/michael_peters/internetauctionsrevisshort.pdf\"> Internet Auctions with Many Traders</a>

We study a multi-unit auction environment similar to eBay. Sellers, each with a single unit of a homogenous good, set reserve prices at their own independent second-price auctions. Each buyer has a private value for the good and wishes to acquire a single unit. Buyers can bid as often as they...

This paper studies an internet trading mechanism similar to the one described in Peters and Severinov (2001) in a market where traders values are interdependent. It is shown that under reasonable conditions this mechanism has a perfect Bayesian equilibrium which supports allocations that...

In modelling competition among mechanism designers, it is necessary to specify the set of feasible mechanisms. These specifications are often borrowed from the optimal mechanism design literature and exclude mechanisms that are natural in a competitive environment; for example, mechanisms that...

The paper contrasts the exact equilibria of games where sellers compete in price with the rational expectations equilibria of these games. It is shown that the distribution of prices offered by sellers in both the exact and rational expectations equilibrium converge weakly to the same limit as...
