Modifying the uniform-price auction to eliminate ‘collusive-seeming equilibria’
Abstract
The uniform-price auction is used in many regional electricity procurement auctions
and its “collusive-seeming equilibria” have been linked to potential exercise of market
power. Such equilibria do not exist, however, if a small amount of cash is split among
rationed bidders. To shed light on what drives this result, I also examine variations
in which the auctioneer is able to increase and/or decrease quantity after receiving
the bids. “Increasable demand” also eliminates all collusive-seeming equilibria. These
results suggest ways to modify the uniform-price auction in order to reduce the potential
exercise of market power.
