Judith Spirig (UCL)
Tuesday 10 December 2024 14:00 - 15:30
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.

About this event
Extensive research on judicial politics has documented disparities in adjudication and biases in judging. Yet, lacking statistical methods to infer individual preferences from group decisions, existing studies have focused on courts publishing individual judges' opinions, leaving a gap in understanding collegial courts that report only collective and unanimous (`per curiam') panel decisions. We introduce a statistical methodology to identify the most fitting decision-theoretic models for such collective decisions, infer judges' individual preferences, and quantify the inconsistency in the court's decisions. This methodology is applicable in various small group decision-making contexts where group assignments are repeated and exogenous. Applying it to the Swiss appellate court for asylum appeals, where decisions are made in three-judge panels, we find that in 45% of cases, the panel chair can overrule the median judge. Although judges' preferences vary strongly with partisanship, the partially collective decision making of the panel moderates this heterogeneity.
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 SAL 3.05, unless specified otherwise.
Seminar coordinators: Aliz Toth, Carl Muller Crepon and Nirvikar Jassal
