We find new equilibria of minimum-revenue core-selecting (MRCS) auctions that, in contrast to previously identified equilibria, involve overbidding - bidding more than one's true value for some packages of goods. With full information, every MRCS auction in every possible setting has equilibria...

The U.S. Department of Justice and Federal Trade Commission issued draft Vertical Merger Guidelines on January 10, 2020. In the discussion on vertical merger policy, some commenters have relied on surveys of the empirical economic literature to justify a procompetitive presumption. This comment...

We study a setting in which dynamically arriving items are assigned to waiting agents, who have heterogeneous values for distinct items and heterogeneous outside options. An ideal match would both target items to agents with the worst outside options, and match them to items for which they have...

Stable matching mechanisms are used to clear many two-sided markets. In practice, these mechanisms leave many agents on both sides unmatched. What factors determine the number of unmatched agents, and the quality of matches that do form? This paper answers this question, with a particular focus...
