我们分析了工资的不确定性对自雇工人的劳动力供给的影响，使用PSID数据对自雇的美国男性。过去工资的标准差作为衡量工资不确定性的尺度，是男性自营职业劳动力供应的关键决定因素，具有重大的积极影响。相反，（工具化的）工资或其他解释变量没有影响。我们的研究结果与自雇人士的“自我保险”是一致的，以应对更大的不确定性，工作时间更长，他们也可以帮助解释为什么自雇美国人的平均工作时间更长，平均工资低于员工同行。
We analyse the effects of wage uncertainty on the labour supply of self-employed workers, using PSID data on self-employed American males. The standard deviation of past wages, as a measure of wage uncertainty, is the key determinant of male self-employed labour supply, with a significant positive effect. In contrast there is no effect from the (instrumented) wage or other explanatory variables. Our findings are consistent with the self-employed 'self-insuring' in response to greater uncertainty by working longer hours, and they can also help explain why self-employed Americans work longer average hours for lower average wages than their employee counterparts.
