Chen Yi-Chun is the fifth from the department to be elected to the fellowship

Chen Yi-Chun is one of 25 new Fellows of the Econometric Society this year. He joins four other department faculty who were elected previously. Chew Soo Hong was elected in 2011 while Jessica Pan, John Quah and Satoru Takahashi were elected in 2020.

Chen Yi-Chun studies how higher-order beliefs—what agents believe about others’ beliefs, and so on—shape strategic behaviour. With co-authors, he designs mechanisms that deliver the target social outcome in every equilibrium, even when agents’ beliefs are misspecified. In parallel, he also analyses how incomplete information affects the stability and efficiency of matching outcomes.

His recent research draws on tools across domains to unlock new insights—for instance, using linear regression to harness higher-order beliefs for information aggregation; applying information design to optimal single-object auctions as well as multi-product monopoly pricing; and bringing matching theory to the axiomatization of correlation preferences.
