Panel data show that between 2001 and 2014 Norwegian industries’ increasing aggregated operating profits per employee increased average wages and wage inequality. The data imply that increasing profits, perhaps unsurprisingly, induce a wage premium. The data further imply that employees earning high incomes at the outset had the highest wage increase percentage-wise. Decreasing operating profits per employee had opposite but less robust effects on average wages and wage inequality. Panel data Granger causality tests finally showed that average wages, but not wage inequality, reversely and positively affect operating profits per employee.

营业利润是否会导致高收入或低收入员工平均分担工资溢价？

面板数据显示，在2001年至2014年之间，挪威各行业的平均每位员工营业利润不断增长，加剧了平均工资和工资不平等。数据表明，利润增加（也许不足为奇）会引起工资溢价。该数据进一步暗示，一开始就获得高收入的员工的工资涨幅百分比最高。每名员工的营业利润减少对平均工资和工资不平等的影响相反，但影响较小。面板数据格兰杰因果关系测试最终表明，平均工资而非人均工资不平等现象对每个员工的营业利润产生了积极的影响。
