Wage differentials across firms: an application of multilevel modelling

Abstract

Multilevel modelling techniques are applied to a dataset that matches firms and workers, to pinpoint and explain contrasts among company wage policies. Results indicate that wage differences across firms are statistically significant, affecting every parameter of the pay policy (returns to schooling, tenure, experience, the penalty imposed on newly hired workers and on women). Gross labour productivity, average schooling in the firm, firm size and economic sector are relevant forces shaping the contrast between employers' pay policies.
