本文使用中国社会科学院经济研究所2006年的农民工调查数据,考察了农民工是否能够因恶劣的工作条件而获得补偿性工资差异。OLS估计结果表明,农民工在城市劳动力市场并不能获得补偿性工资差异,这说明城市劳动力市场对农民27-而言还是分割的。考虑到OLS估计可能会因度量误差和遗漏变量而偏离真实值,本文还使用了工具变量法对OLS的估计偏差进行了纠正。工具变量法的估计结果进一步支持了基于OLS的分析。本文也使用了Lee(2007)的方法,在处理恶劣工作条件这一变量的内生性的前提下,考察了恶劣工作条件在不同条件分位点上对工资的影响,发现农民工无论处于所有工资条件分布的高端还是低端,都无法获得补偿性工资性差异。
Using the 2006 migrants survey data, this paper intends to check the existence of compensating wage differentials for rural migrants. OLS estimates reveal that rural mi- grants do not enjoy compensating wage differentials for job disamenities, suggesting the presence of a segmented labor market in which rural migrants are involved. IV estimates further corroborate our previous findings. This paper also examines the effect of job disamenities on wage across conditional quantiles while correcting for the endogeneity bias following Lee (2007). Quantile regressions reveal no evidence of the existence of compen- sating ware differentials for migrants.
