Many of our seminars and public events this year will continue as online seminars or as online and in person. Please check our website listings and Twitter feed @STICERD_LSE for updates.

Unless otherwise specified, current restrictions mean in-person seminars are only open to members of the LSE community (those with a valid LSE ID card).

Those unable to join the seminars in-person are welcome to participate via zoom.

About this event

We study a two-sided search-and-matching model in which agents invest before entry. In every period, agents incur an additive search cost, pairs meet at random and bargain over prices. Inefficiencies can be caused by a potential hold-up problem and mismatches between skills. We make three major points. First, despite the potential inefficiencies, a second welfare theorem holds: the constrained efficient allocation is an equilibrium. Second, we establish a general assortativity result, provide conditions for uniqueness, and characterize the outcomes in symmetric two-skill economies. Third, we show that the efficient outcome can be discriminatory in the marriage market.

Economic Theory Seminars are held on Thursdays in term time at 15:30-17:00, ONLINE or ONLINE AND IN PERSON at the same time.

Seminar organisers: Dr Andrew Ellis and Dr Francesco Nava.
