Establishment size and task-specific wages: Evidence from historical contract data

This study examines whether task-specific jobs are rewarded differently across establishments of different sizes and whether these rewards vary across distinct technologies. We found that the aggregate premium estimates on the impact of size on wages conceal significant differences between tasks and technologies and that these differences reflect unobserved individual heterogeneity. The role of self-selection of more productive workers into larger establishments is particularly substantial in the case of abstract tasks.
