Hector Chade (Arizona State University), joint with Victoria Marone, Amanda Starc, and Jeroen Swinkels

Thursday 08 June 2023 15:30 - 17:00

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

Unless otherwise specified, in-person seminars are open to the public.

Those unable to join the seminars in-person are welcome to participate via zoom if the event is hybrid.

About this event

We study a general screening model that encompasses the problem facing a price-setting insurer that offers vertically differentiated contracts to consumers with multiple dimensions of private information. We combine theory and calibrated numerical analysis to provide three novel results: (i) even in the presence of both selection and moral hazard, optimal menus satisfy intuitive conditions that generalize the literature on multidimensional screening and shed light on insurer incentives; (ii) the insurer’s problem with an infinite number of contracts is well-approximated with only a small set of contracts; and (iii) under conditions that are economically innocuous in our setting, the problem becomes dramatically simpler and can be solved using familiar graphical analysis. W illustrate the use of the simplified problem to provide intuition about optimal menus, contrast the incentives of a monopolist and a social planner, and evaluate policy interventions in a monopoly market.

Economic Theory Seminars are held on Thursdays in term time at 15:30-17:00, both ONLINE and IN PERSON in SAL 3.05.

Seminar organisers: Dr Andrew Ellis and Dr Christopher Sandmann.
