Yiyuan Xie — economist · mechanism design

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

My research focuses on institutional design under private information and private property rights. My current work reinterprets classic results in mechanism design through the lens of property rights, decentralised institutions, and information constraints. More broadly, I study how mechanism design and information design can be integrated into a unified institutional framework.

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.
