Horizontal shifts in bid curves observed in wholesale electricity markets are consistent with Cournot competition. Quantity competition reduces the informational requirements associated with evaluating market performance because the markups of all producers then depend on the same inverse...

When faced with budget-constrained bidders, all-pay auctions revenue-dominate standard auctions (Örst and second-price), which, in a competitive market, gives an edge to the all-pay format. An equilibrium in which sellers compete with standard auctions fails to exist if the all-pay format is...
