We present evidence of sector earnings gap decomposition in the Ghanaian labor market for the period 2009–2015. With a sample of 200 workers from state‐owned enterprises (SOEs) and 250 from privatized enterprises (PEs), we use the Mincerian wage equation, with the Oaxaca–Blinder and Juhn–Murphy–Pierce decompositions on earnings, and observe that the two ownership categories differ regarding personal characteristics and institutional factors, with employees in PEs receiving a wage premium (64%) over their SOE counterparts. In addition, employee observed characteristics explain only 36% of the earnings differential. The PE‐SOE differential is small at the top quartiles compared with previous studies. However, individuals at the bottom of the wage distribution in the public sector earn far lower than their counterparts in the private sector, signaling that low‐level SOE workers have not gained much despite the single spine salary structure policy initiated by the Government in 2008 to bridge the wage gap. This study contributes to wage analysis and decomposition by focusing on individual and institutional factors—personal characteristics, sector, and government policy—that are traditionally not combined in extant literature.

所有权类型和收入差距分解：来自加纳劳动力市场的证据

我们提供了2009-2015年期间加纳劳动力市场部门收入差距分解的证据。我们对200名来自国有企业（SOE）的工人和250名来自私有化企业（PE）的工人进行了抽样，我们使用Mincerian工资方程，对收入进行了瓦哈卡—布林德和尤恩·墨菲—皮尔斯的分解，并观察到两者所有权类别在个人特征和制度因素方面有所不同，私募股权公司的雇员比国有企业的雇员享有工资溢价（64％）。此外，员工观察到的特征只能解释收入差异的36％。与以前的研究相比，最高四分位数的PE-SOE差异很小。但是，在公共部门的工资分配最底层的人的收入远低于私营部门的同龄人，这表明尽管政府于2008年推出了单一脊柱式薪资结构政策以弥合工资差距，但低水平的国有企业工人并未获得太多收益。这项研究通过关注个人和制度因素（个人特征，部门和政府政策），对工资分析和分解做出了贡献，这些因素传统上在现有文献中并未合并。
