Working paper title: Refugees and Entrepreneurship: Evidence from Ukrainians in Poland

By: Pierre-Louis Vézina, Cevat Giray Aksoy and Piotr Lewandowski

Abstract

We examine business creation by Ukrainian refugees in Poland following the Russian invasion of Ukraine. Using registry data, we show that Ukrainians started 38,833 firms in 2022–23, accounting for 7% of all new registrations in Poland. We link this entrepreneurship to refugees in two ways. First, our survey shows that 58% of post-invasion Ukrainian founders registered as refugees. Second, cross-county regressions show that a 10% increase in adult male Ukrainian refugees is associated with a 2.71% increase in Ukrainian firm registrations. We then show that new Ukrainian businesses stimulate rather than crowd out Polish entrepreneurship. Using a shift-share strategy based on refugee shocks and Ukrainians’ comparative advantage, we find that a 10% increase in Ukrainian registrations led to 2.31% more Polish firms. Survey evidence suggests two mechanisms: emulation, with 59% of Ukrainian owners reporting Polish entrepreneurs starting similar firms, and supply-chain linkages, with 88% of Ukrainian firms engaged in local business-to-business transactions.
