Stars and Misfits: Self-Employment and Labor Market Frictions
研究发现进入自雇就业的人多来自收入和能力的极端分布，通过多任务职业选择模型解释劳动力市场摩擦导致的错配，并用韩国面板数据验证了模型预测。
Recent evidence has shown that entrants into self-employment are disproportionately drawn from the tails of the earnings and ability distributions. This observation is explained by a multitask model of occupational choice in which frictions in the labor market induce mismatches between firms and workers, and misassignment of workers to tasks. The model also yields distinctive predictions relating prior work histories to earnings and to the probability of entry into self-employment. These predictions are tested with the Korean Labor and Income Panel Study, from which we find considerable support for the model.
