A Reexamination of the Federal-Private Wage Differential in the United States
用新数据重新检验美国联邦政府与私营部门的工资差异，发现差异比以往研究小，因为之前未控制详细的职业和地点特征。
The federal-private wage differential is reexamined with recent data. Using specifications similar to those used in three previous studies, the author finds that the federal-private wage differential has narrowed since the 1974-79 period analyzed in those studies. In addition, he discovers that wage differentials based on specifications used in the literature are biased upward because the previous studies did not control for detailed occupational and locational characteristics of workers. Corrected point estimates of the wage gap are much smaller than previous estimates in the literature. Differences in the gap across demographic groups, occupations, and locations are also discussed.
