We analyze a dynamic market for lemons in which the quality of the good is endogenously determined by the seller. Potential buyers sequentially submit offers to one seller. The seller can make an investment that determines the quality of the item at the beginning of the game, which is...

We study whether allowing players to sign binding contracts governing future play leads to reputation effects in repeated games with long-run players. We proceed by extending the analysis of Abreu and Pearce (2007) by allowing for the possibility that different behavioral types may not be...

We develop a Bayes–Nash analysis of the generalized second-price (GSP) auction, the multi-unit auction used by search engines to sell sponsored advertising positions. Our main result characterizes the efficient Bayes–Nash equilibrium of the GSP and provides a necessary and sufficient...
