A simple theory of Pareto-distributed earnings
提出一个简单模型，内生地生成顶层收入的帕累托分布。工人占据不同利基市场，收入由利基内劳动力供给和向下倾斜的劳动需求曲线决定，最高收入者出现在工人稀少的利基中。
I introduce a simple model which endogenously generates a Pareto distribution in top earnings. Workers inhabit different niches, and the earnings of a worker is determined by the niche-specific supply of labor and a downward-sloping labor-demand curve. The highest paid workers are the ones that inhabit a niche with few other workers. A Pareto tail in earnings emerges as long as the labor-demand curve has a limit elasticity and the distribution of workers over niches satisfies a regularity condition from extreme-value theory, satisfied by virtually all continuous distributions in economics.
