Did Henry Ford Pay Efficiency Wages?
研究亨利·福特1914年引入五美元日薪的案例，评估效率工资理论对工资和就业决定的解释力，发现该案例有力支持了效率工资理论。
We examine Henry Ford's introduction of the five-dollar day in 1914 in an effort to evaluate the relevance of efficiency wage theories of wage and employment determination. We conclude that the Ford experience strongly supports the relevance of these theories. Ford's decision to increase wages dramatically is most plausibly the consequence of labor problems of the kind efficiency wage theorists stress. The structure of the five-dollar day program is consistent with the predictions of efficiency wage theories. There is vivid evidence that the introduction of the five-dollar day resulted in substantial queues for Ford jobs. Significant increases in Ford productivity and profits accompanied the new regime.
