Do Firms Pay Efficiency Wages? Evidence with Data at the Firm Level
利用企业调查数据检验效率工资假说，发现离职成本与失业对工资的影响符合理论预测，且企业特征通过提高生产率推高工资。
This study tests the efficiency wage hypothesis by estimating wage and quit equations with data from the Employment Opportunity Pilot Project survey of firms. An efficiency wage model is derived that predicts effects of turnover costs and unemployment on wages as functions of first and second derivatives from the quit equation. The model is tested by examining the relationships between the coefficients in the wage and quit equations; the results are generally favorable to efficiency wage theory. Other important findings are that firm characteristics raising workers' productivity tend to raise wages and that a rise in turnover costs reduces quits. Copyright 1993 by University of Chicago Press.
