This paper uses firm-level panel data of on-the-job training to estimate its impact on productivity and wages. To this end, we apply and extend the control function approach for estimating production functions, which allows us to correct for the endogeneity of input factors and training. We find that the productivity premium of a trained worker is substantially higher compared to the wage premium. Our results are consistent with recent theories that explain work-related training by imperfect competition in the labor market.

This paper uses representative panel data on 1,701 Bulgarian and 2,047 Romanian manufacturing firms to analyze how price-cost margins are affected by privatization and competitive pressure. Privatization is associated with higher price-cost margins. This effect is stronger in highly competitive sectors, which suggests that the creation of competitive markets and privatization go together. It also suggests that privatized firms reduce costs rather than increase prices, as in highly competitive markets firms are more likely pricetakers. Import penetration is associated with lower price-cost margins in sectors where product market concentration is high, but in more competitive sectors this effect is reversed.
