Cross‐Sectional Versus Panel Income Approaches: Analyzing Income Distribution Changes for the Case of Mexico
从理论和实证上调和了横截面不平等变化与面板收入变化模式，利用墨西哥面板收入数据发现面板变化在几乎所有时期都是收敛的，且这种均等化主要与就业状态和部门变化相关。
In this paper we reconcile, both theoretically and empirically, changes in cross‐sectional inequality with patterns of panel income changes during periods of economic growth and decline. Using panel earnings data from Mexico, we find that the panel changes are convergent in almost every period, the reason being that a large number of individuals experience small convergent earnings changes while a small number of individuals experience large and convergent earnings changes. We examine what accounts for the inequality of log‐earnings at a point in time and for the inequality of the log of earnings averaged over five quarters. We find that the equalization brought about by panel earnings changes is mainly associated with changes in employment status and in sector of employment and not by personal characteristics such as schooling, age, and gender.
