Ethnic wage differences in Malaysia: parametric and semiparametric estimation of the Chinese-Malay wage gap
使用参数和非参数方法估计马来西亚华裔与马来裔的工资方程，校正样本选择偏差后发现，华裔与马来裔的工资差距在女性中比男性更大，且非参数估计结果削弱了参数估计中发现的强烈歧视效应。
Parametric and semiparametric estimated wage equations, which correct for sample selection bias, are used to assess the returns to eduction and extent of ethnic ‘discrimination’ in (Peninsular) Malaysia. In particular, this paper focuses on the level of ‘discrimination’ between Malay and Chinese men and women. The Andrews–Schafgans (1998) estimator is used to estimate consistently the wage equation intercept in the semiparametric case. The results show that the Chinese–Malay offered wage difference typically is larger in absolute value among women than men. The strong ‘discrimination’ favouring Chinese over Malays observed using the parametric results is negated by the semiparametric results.
