Qualitative analysis of Bayes-Nash equilibrium in weak asymmetric auctions

摘要

We propose a simple qualitative methodology for improving the understanding of the nature of equilibrium strategies in asymmetric first-price sealed-bid auctions when departures from symmetry are weak. We exemplify this methodology through the exposition of three examples already studied in literature (Maskin and Riley, 2000a; Fibich and Gavious, 2003; Bajari, 2001).
