During the Soviet Union’s First Five-Year Plan, Western know-how and technology were extensively infused into industry through technical assistance agreements and work contracts with specialists and foreign companies. We study the causal effects of this purposeful state-led policy on labor productivity using the largest single recruitment effort of Western expertise, namely Karelian Technical Aid. This allows us to exploit exogenous variation in transfer of technology within one sector: the wood processing industry. Combining detailed individual-level data on over 5,000 North American specialists with a novel panel of accounting data on the universe of Soviet enterprises in Karelia and the Northern Region during the interwar period, we document large and persistent causal productivity gains. Important drivers of successful technology absorption were local human capital and the absence of language barriers.

NON-TECHNICAL SUMMARY
FOCUS
During Stalin’s interwar industrialization, the Soviet Union implemented one of history’s largest technology transfer programs. Several hundred industrial projects were designed by foreign engineers, built under foreign supervision, and equipped with the most advanced technology, all in just a few years (1928-1934). This paper quantifies the causal effect of Western technology transfer on Soviet labor productivity by focusing on the largest single recruitment effort of foreign expertise at that time, namely “Karelian Technical Aid” (KTA). In 1931-1933, more than 5,000 American and Canadian specialists of ethnic Finnish origin were recruited to modernize the wood processing industry in Soviet Karelia.
CONTRIBUTION
The paper makes three key contributions to the literature. First, it provides causal evidence on the impact of Western technical assistance using modern identification techniques applied to a historically significant but understudied case of Soviet industrialization. Second, it offers new insights into firm-level technology adoption within purposeful industrial policy. Third, it contributes to understanding how skilled immigration affects productivity through knowledge spillovers. The analysis combines two novel datasets: an individual-level registry of foreign workers and enterprise-level accounting data covering the universe of interwar enterprises in Soviet Karelia and the closest comparison region, namely the neighboring Northern Region, from 1925-1938. Both Karelia and the Northern region were remote areas in the North-west of the Soviet Union and specialized in the wood processing industry. The research design employs two-way fixed effects estimation comparing treated enterprises in Karelia and untreated enterprises in Karelia and the Northern region, complemented by an instrumental variables strategy exploiting geographical settlement restrictions for American and Canadian Finns imposed by the Soviet authorities.
FINDINGS
The program substantially increased labor productivity in the wood-processing industry. Enterprises in the settlements with the presence of American and Canadian Finns experienced approximately 60% productivity gains compared to non-treated enterprises. Effects emerged within two years after the start of the KTA program and persisted until the end of our observation period in 1938. Productivity gains were larger where local workers had higher initial human capital and where language barriers were smaller. Cost-benefit analysis based on our estimates suggests the KTA program was efficacious and would still have been viable at as much as almost four times higher wages for foreign workers.
