Empirical Analysis of Wage Differentials Among Public Servants in Nigeria

Abstract

This study investigated wage differentials among public servants in Nigeria with four specific objectives. Both primary and secondary (salary structures) data were used for this study. The work employs a stratified sampling technique in collecting the primary data. We employ the quantile regression and logistic models in our analysis. Using a sample of 840 employees, in accordance with our theoretical priors, the empirical result support the standard inverse relationship between wage differential and labour turnover. That as state workers’ wages increases, the probability of a State worker leaving to Federal civil service falls by 0.2901. Wage differences by gender are well pronounced among the low cadre than high cadre of manpower, in favour of male employees and in favour of female in the middle cadre of manpower. The intergovernmental workers analysis reveals that Bayelsa State workers earn higher than other States selected, including Federal workers. Enugu State workers are seen to earn lower than the rest States workers selected. The inter-sector wage differences; health workers earn higher than other sectors workers selected for this study. However few recommendations were given to address the problem of wage differential in Nigeria.
