研究了2022年2月24日入侵以来俄乌战争中外国战士死亡的政治经济学，分析了人口因素、军事制度和国际贸易如何影响各国赴乌或援俄战士的死亡人数，并发现经济自由和健全民主对个人参战决策有重要作用。
Abstract This empirical study extends the public choice literature on the allocation of death during war by examining the political economy of foreign fighter deaths in the Russo-Ukrainian War since the 24 February 2022 invasion. The study explores the roles played by various demographic factors, military institutions, and international trade relations in determining the number of foreign fighters from a variety of countries who have died in support of either Ukraine or Russia during the Russo-Ukrainian War. Unlike other related studies, this study also investigates the importance of, and finds evidence in support of, both economic freedom and a robust democracy in shaping the choices made by individuals around the globe to venture to, and die fighting on, the battlefields of Ukraine.
