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
Elections aggregate information of citizens who gather information, in part from mainstream news, but possibly to a large extent from their different echo chambers which filter news in particular ways. We study information aggregation and electoral outcomes in the presence of endogenous echo chambers. Citizens choose their echo chambers in a self-serving way, in part to shield them from the outside world (mainstream news) and thus preserve their political faith as often as possible. The key asymmetry is how isolated citizens are, namely how much they trust/distrust mainstream news to begin with. We study in several contexts the electoral advantage that the side with more isolated followers may have. This advantage can turn into a sure electoral victory regardless of the true state of the world, thereby failing information aggregation, in some instances. Information aggregation can still fail if voters can abstain, don't fully trust their echo chamber sources, and with echo chamber disinformation.
The Political Science and Political Economy (PSPE) research group at the LSE brings together faculty and PhD students who do quantitative and/or formal research on political institutions, political behaviour, public policy, and political economy.
The PSPE Research Seminar provides a venue for researchers (mostly from outside of the LSE) to present their work.
These seminars are held on Tuesdays in term time at 14.00-15.30, both ONLINE AND IN PERSON in room 32L 3.05, unless specified otherwise.
Seminar coordinator: Dr Stephane Wolton
