Wage differentials across firms: an application of multilevel modelling
运用多层次模型分析企业与工人匹配数据，发现企业间工资差异显著，且影响工资政策的各个参数，如教育回报、工龄、经验等；企业生产率、平均教育水平、规模和行业是造成差异的重要因素。
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.
