Yiyuan Xie · Coasean–Hurwiczian theorist

Welcome! I am an Education-focused Lecturer at the School of Economics, UNSW Sydney. 

My research develops a Coasean–Hurwiczian approach to mechanism design. Following Hurwicz, I study institutions as mechanisms for coordinating private information and incentives. Following Coase, I treat property rights and decentralized decision makings as primitives. This perspective leads me to revisit canonical impossibility results in trade, public goods provision, asking whether inefficiency reflects an unavoidable informational constraint or an institutional setting that centralizes too much authority.

I have presented, or am scheduled to present, my research at major international conferences, including ESEM 2026 in Dublin, NASM 2026 in Atlanta, AMES-CSW 2026, EWMES 2025, WAMS and LAEF 2015–2018, and the Chicago Fed Summer Workshop on Money, Banking, Payments and Finance in 2013.

I received the Best Discussant Award at the WAMS and LAEF Conference in 2015. I served as President of the Economic Research Student Association at UNSW in 2013–2014.
