This study examines whether foreign direct investment inflows facilitate upgrading of export quality in host countries. The analysis focuses on the Russian Federation and uses customs data merged with firm-level information from ORBIS. The results show a positive relationship between the quality of products exported by domestic firms and the presence of foreign affiliates in the upstream (input-supplying) industries. This relationship is present irrespective of export destination or FDI origin. The results are robust to using different proxies to measure product quality.JEL Classification numbers: F14, F23, O24. *I am grateful to Beata S.

All errors are my own.1 For instance, Javorcik, Keller and Tybout (2008) report that small Mexican producers meet with their input suppliers (usually foreign affiliates) every 6 months to learn about the possibilities of upgrading their products. Suppliers provide the necessary inputs and often prepare a new formula for the product based on these inputs.
