Estimating the Labor Market Signaling Value of the GED
利用各州不同的GED通过标准，分离出GED证书的信号价值，发现它使年轻白人辍学者的收入提高10%至19%，但对少数族裔辍学者无显著影响。
This paper tests the labor market signaling hypothesis for the General Educational Development (GED) equivalency credential. Using a unique data set containing GED test scores and Social Security Administration (SSA) earnings data, we exploit variation in GED status generated by differential state GED passing standards to identify the signaling value of the GED, net of human capital effects. Our results indicate that the GED signal increases the earnings of young white dropouts by 10 to 19 percent. We find no statistically significant effects for minority dropouts.
