I am a PhD student in the Department of Economics. I obtained my Bachelor's degree from Peking University in 2021. I work on political economy and innovation in both historical and contemporary settings. Using machine learning and language models, I build novel datasets and measures from unstructured archival and modern records to study the gains from empire, the diffusion of innovation, and firms' responses to external pressures.

I am on the 2026-2027 job market.

Battles and Spoils: Evidence from the British Museum

Abstract: States rely on agents to fight their wars yet often pay them little. I ask whether battles systematically generated spoils and whether military officers benefited from them in the context of the British Empire. First, using novel British Museum catalog data and the battles that British forces fought between 1816 and 1913, I find that the British Museum acquired more artifacts from a battle's location in the year after the battle, and that acquisitions stayed higher for decades. These spoils arose from new access to a place's wealth and from direct taking on the field. The increase followed British victories, was larger in places Britain never ruled, and was stronger for artifacts the British Museum acknowledges as taken in war. Spoils were also turned into cash through prize sales and kept appearing in auction houses for decades. Second, battles generated private gains for military officers. I link manually collected biographies of battle commanders to their wealth at death. Commanders of the battles that were followed by larger inflows of artifacts to the British Museum left higher probated wealth, controlling for pre-battle rank, personal characteristics, and family background. After the Indian Mutiny, a war rich in spoils, officers purchased more commissions in the regiments that had served in the campaign. Together, the results show that imperial warfare generated spoils on a large scale, and that the gains reached not only the state but also the officers who carried it out.
