在本文中，我们考虑了教育、培训、工会和其他活动对工资影响的基本自我选择模型。我们表明，过去的模型忽略了活动的“奖励异质性”。个体之间在活动回报率上的差异——作为选择偏差的来源。我们对这种异质性进行了建模，展示了它的存在是如何被测试的，并得出了它对工资和福利收益的影响。实证应用为这种异质性提供了强有力的支持。
In this paper we consider the basic self-selection model for the effects of education, training, unions, and other activities on wages. We show that past models have ignored "heterogeneity of rewards" to the activity--i.e., differences across individuals in the rate of return to the activity--as a source of selection bias. We model such heterogeneity, show how its presence can be tested, and draw out its implications for the wage and welfare gains to the activity. An empirical application provides strong support for such heterogeneity.
