Sector choice, multiple job holding and wage differentials: Evidence from Poland
利用波兰数据研究公共与私营部门间的工资差异如何影响劳动者的部门选择及兼职决策，发现私营部门存在显著工资溢价，且工资差距越大，大学学历者兼职意愿越强。
This article uses data from Poland to investigate the role played by wage differentials, between the public and private sectors, in influencing sector choice and the decision to moonlight. Standardising for worker characteristics and allowing for sector selection effects, we find (i) a substantial private sector wage premium, (ii) wage differentials are a significant determinant of sector choice, and (iii) the desire to moonlight is particularly strong among those who face the greatest wage gap, that is, university educated employees.
