On the Positive Correlation between Income Inequality and Unemployment
用标准工作搜寻模型解释结构性失业加剧收入不平等的实证规律，并给出一个可直接计算工资收入基尼系数的通用公式。
Two papers published in this journal (Jantti, 1994, and Mocan, 1999), among others, find empirical evidence that "increases in structural unemployment have a substantial aggravating impact on income inequality." The main point of this work is to show that standard job-search models can help us understand this empirical regularity. As a byproduct of the analysis, the paper also provides a closed-form general expression that enables direct calculation of the Gini coefficient of wage-income inequality as a function of any arbitrary initial distribution of wage offers. Three numerical examples illustrate the results. Copyright by the President and Fellows of Harvard College and the Massachusetts Institute of Technology.
