本文回顾了Lazear和摩尔[Q. J. Econ. 99（1984）275]，发现经验经验收入概况是平坦的自雇（SE）工人比工资/工资（SW）工人。这一发现支持了拉泽尔的契约理论，该理论认为，企业使用生命周期，backloaded支付系统，以解决企业和工人之间的委托代理问题。本文再现了Lazear和摩尔的调查结果，对最近的数据，并认为另一种解释。特别是，本文认为，自雇工人面临更多的工资变化，但也享有更高的人力资本回报比工资/工资工人。基于这些假设的模型产生了更平坦的经验收入概况，因为自雇工人以更多的人力资本开始职业生涯。由于机会成本，他们在工作中的人力资本投资较少。本文开发的模型中没有发现的Lazear合同理论的影响，并得出结论，发展支持这些影响。
This paper revisits the study of Lazear and Moore [Q. J. Econ. 99 (1984) 275], which found that empirical experience–earnings profiles were flatter for self-employed (SE) workers than salary/wage (SW) workers. This finding supports Lazear's contract theory, which argues that firms use life-cycle, backloaded payment systems to work around principal–agent problems between firms and workers. This paper reproduces the Lazear and Moore findings on more recent data and argues for an alternative interpretation. In particular, this paper argues that self-employed workers face more wage variation, but also enjoy a higher return for human capital than salary/wage workers. A model based on these assumptions produces flatter experience–earnings profiles, since self-employed workers start their careers with more human capital. Due to opportunity cost, they invest less in human capital on the job. This paper develops implications of the model not found in the Lazear contract theory and concludes by developing support for these implications.
