More on Identification in Detailed Wage Decompositions
指出传统工资分解中个体虚拟变量贡献无法识别的问题，并提出一个简单解法，用西班牙劳动力市场数据演示。
Wage decompositions are often used to decompose wage differentials of two demographic groups into differences in characteristics and differences in returns to those characteristics. The latter part is used as an estimate of the degree of discrimination. A problem with this approach is that the contributions of individual dummy variables to the wage decomposition are not identified. This note proposes a simple solution to the identification problem. The solution is illustrated with an empirical application to Spanish labor market data. © 2004 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
