标题： The Economic Costs of the Russia-Ukraine War: A Synthetic Control Study of (Lost) Entrepreneurship

摘要： 这项合成控制研究量化了自2014年克里米亚入侵以来， Russo-Ukrainian 战争在经济上造成的成本，具体表现为两国错失的企业家活动。与合成反事实相比，乌克兰的个体经营者数量减少了67.5万，相当于相对损失了20%。乌克兰中小企业的数量暂时减少了7.1万（14%），并在冲突五年内恢复。相比之下，俄罗斯在冲突五年内失去了超过140万家中小企业（42%）。俄罗斯中小企业的消失既由于新企业创建减少，也由于现有企业关闭增多。 显示英文摘要

摘要： This synthetic control study quantifies the economic costs of the Russo-Ukrainian war in terms of foregone entrepreneurial activity in both countries since the invasion of Crimea in 2014. Relative to its synthetic counterfactual, Ukraine's number of self-employed dropped by 675,000, corresponding to a relative loss of 20%. The number of Ukrainian SMEs temporarily dropped by 71,000 (14%) and recovered within five years of the conflict. In contrast, Russia had lost more than 1.4 million SMEs (42%) five years into the conflict. The disappearance of Russian SMEs is driven by both fewer new businesses created and more existing business closures.
