This article examines if there is a wage gap between public and private mining (and quarrying) workers in India, using the NSS data (2004–2005, 2009–2010 and 2011–2012). We employ linear and quantile regressions to estimate the wage gap. The ordinary least squares (OLS) results suggest that workers in the public sector mines (and quarries) earn 59 per cent more than their private sector counterparts. However, the wage gap is not uniform across the conditional wage distribution. The quantile regression estimates show that the magnitude of the wage gap is larger at the bottom quantile than at the top; the gap reduces as we move up the wage distribution. Observations drawn from our sub-sample analysis concur with these findings. JEL Classification: J21, J31, J45

印度采矿和采石业中的公共-私人工资差距

本文使用NSS数据（2004-2005年，2009-2010年和2011-2012年）来检验印度的公共和私人采矿（采石）工人之间是否存在工资差距。我们采用线性和分位数回归来估计工资差距。普通最小二乘（OLS）结果表明，公共部门矿山（和采石场）的工人收入比私营部门的工人高59％。但是，在有条件的工资分配中，工资差距不是统一的。分位数回归估计显示，最低分位数的工资差距大于最高分位数的工资差距；随着我们提高工资分配，差距会缩小。从我们的子样本分析中得出的观察结果与这些发现一致。JEL分类：J21，J31，J45
