The French data has already been used to estimate models of wage determination that include both individual and firm effects. The firm-level averages of these measures are related to a number of important outcomes: profitability, productivity, capital/labor ratios and survival rates.

This research is important because it will enhance our understanding of wage determination and the dynamics of job creation and destruction at the level of the firm. ***
