Wage structure and firm performance

This study describes the human resources management along several dimensions, based on administrative data (DADS and tax data): wage schedule both in terms of level but also dispersion, stability of the workforce, proportion of different qualifications and age, share of subsidized jobs ... A typology of these companies is available from these dimensions. Then we compare these wage structures with the performance. We observe that the most productive firms are also those who pay the highest wages, even after taking into account their specific characteristics (size, sector) and those of their employees. The link between wage dispersion and the productivity is more difficult to characterize: the estimate parameters are very sensitive to the empirical specification.
