Public versus private sector wage gap in Egypt : evidence from quantile regression on panel data

الملخص EN

wage distribution during 1998-2012 using Egyptian Labor Market Panel Survey.

We estimate the public-private sector wage gap with Mincer wage equations both at the mean and at different quantiles of the wage distribution.

In this process we take into account observable and unobservable characteristics of the individuals using the panel feature of the data with a fixed effects model.

We address sector of employment selection issue for both males and females.

We find that there is very little evidence of sample selection in our data.

Therefore, we present both the selection corrected results and the results with no selection correction.

We find a persistent public sector wage penalty for males and public sector wage premium for females in the face of extensive sensitivity checks.

They are larger when unobserved heterogeneity is taken into account for males but insignificant for females.

They are similar across the quantiles for males but, smaller at the top than at the bottom of the conditional wage distribution for females.

We further examine the public sector wage gap over time and in different sub-groups according to age and education.

The public sector wage penalty for males has decreased recently over time and is larger for the better educated and younger.

We also find substantial regional differences in public sector wage gap for males.
