In the transition to a market economy, the Russian workforce underwent a wrenching period of change, with excess supply of some industrial skills coexisting with reports of skills shortages by many enterprises. This paper uses data from the Russia Competitiveness and Investment Climate Survey and related local research to gain insight into the changing supply and demand for skills over time, and the potential reasons for reported staffing problems and skills shortages, including labor turnover, compensation policies, and the inhibiting effects of labor regulations. It discusses in-service training as an enterprise strategy for meeting staffing and skills needs, and presents evidence on the distribution, intensity, and determinants of in-service training in Russia. It investigates the productivity and wage outcomes of in-service training, and the supportive role of training in firms' research and development and innovative activities. A final section concludes with some policy implications of the findings.
