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-making 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.

Selected conference presentations and acceptances: EEA–ESEM, Dublin (2026); ESAM, Adelaide (2026); NASM, Atlanta (2026); AMES–CSW, Abu Dhabi (2026); EWMES, Cyprus (2025); WAMS and LAEF (2015–2018); Chicago Fed Summer Workshop on Money, Banking, Payments and Finance (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.
