Price Regulations in a Multi-unit Uniform Price Auction

Research output: Contribution to conferencePaperResearchpeer-review


Inspired by recent regulations in the New York ICAP market we examine the effect of different price regulations on a multi-unit uniform price auction. We investigate a bid cap and a bid foor. Given suffciently high total capacities general bid caps always ensure that the market price does not exceed the price cap whereas a selective bid cap for only the larger firms, does not guarantee this outcome. A sufficiently high bid floor always destroys pure strategy equilibria with equilibrium prices above the marginal costs, no matter whether the floor applies to all or only to relatively small firms.
