STICERD Industrial Organisation Seminars

Estimating Equilibrium in Health Insurance Exchanges: Price Competition and Subsidy Design under the ACA

Pietro Tebaldi (University of Chicago)

Monday 17 October 2016 12:30 - 14:00

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

To design premium subsidies in a health insurance market it is necessary to estimate consumer demand and study how different subsidy schemes affect insurers’ incentives. Combining data from the Californian ACA marketplace with a model of insurance demand and insurers’ competition, I identify and estimate demand and cost primitives, and assess equilibrium outcomes under alternative subsidy designs. I find that vouchers are less distortionary than subsidies calculated from market premiums, and — given age-heterogeneity in demand and cost — tailoring subsidies to age leads to an equilibrium where all buyers are better off and per-person public spending is lower.

Industrial Organisation seminars are held on Mondays in term time at 12:30-14:00, ONLINE, unless specified otherwise.

Seminar organiser: Alessandro Gavazza.
