A note comparing the capacity setting performance of the Kreps-Scheinkman duopoly model with the Cournot duopoly model in a laboratory setting

The paper reports the results of 39 laboratory duopoly markets for which pricing institution and participant experience are treatments. Cournot (C) duopolies (quantity precommitment and a price determined to clear the market) are contrasted with Kreps-Scheinkman (KS) duopolies (quantity precommitment and posted prices). Inexperienced participants in KS markets have much more difficulty selecting capacities consistent with the theoretical predictions than do those in C markets. With experience, the differences disappear.Duopoly Laboratory experiment Quantity precommitment Posted prices Price competition Market-clearing prices Experience
