Earnings Distribution and Inequality over Time: Education versus Relative Position and Cohort
构建了一个理论模型分析收入分布随时间的变化，并提出了估计收入不平等的方法，重点比较了相对位置与教育对收入的影响，基于日本各年龄队列的收入数据。
This paper constructs a theoretical model for analyzing the earnings distribution over time and provides an estimation procedure for the inequality of earnings over time. The theoretical model incorporates Gibrat's so-called law of proportionate effect, Galton's regression toward the mean, and serial correlation of the error terms, under the condition that the density function of earnings for each age-cohort in Japan is distributed as log-logistic. An emphasis is placed upon comparison of the influence of the relative position in the distribution with the influence of education on earnings. Finally, the coefficients of variation over time are presented.
