3. Introduction Importance of labour market for welfare
The structure of the market has impact on employment status and influences household income and welfare.
Earnings-cash income and non-cash income
Links between income differences and Inequality

11. Data
General Household Survey Conducted by the former Federal Office of Statistics
Comprises of:
7980 Households – Rural 5842 Urban 2138
36695 Individuals– Rural Urban 9407
Only individuals 15 years and above used in the study. (20904)
Out of which reported earnings – Male 6937 Female 3450

12. RESULTS Qualitative and Quantitative

13. Table 4.1: Labour Market and Activities of the Population

14. Labour Market and Activities of the Population
Economically active 59.3%
Economically inactive 40.7%
Male economically active 75.3%
Female economically active 44.4%
Hence 55.6% of females eligible to work did not work at time of survey as against 24.6% males.
Male labour force participation higher than female

16. Inequality by Gender and Rural- Urban Dimensions
Inequality is about the same between male and female (male 0.459, female 0.466) using Gini coefficient.
Based on Theil measure inequality is higher for female than male (female and male 0.524)
Within group inequality accounts for 98% of inequality by gender. While between gender inequality accounts for only 2%.

17. Inequality by Gender and Rural- Urban Dimensions
Urban-rural inequality is about the same based on Gini coefficient (urban and rural 0.415)
Based on Theil Index, urban inequality is lower than rural (urban and rural 0.672)
Within group inequality dominates at 97% as against between group at about 3%

18. Table 4.4: Inequality by Primary Employment Group, Gender and Rural –urban dimensions

19. Inequality by Primary Employment Group, Gender and Rural –urban dimensions
Inequality is slightly more in self employed male than female (male 0.42 female 0.41)
Theil Index shows that inequality is lower among male than female (male 0.34 and female 0.41)
Within group inequality still accounts more of the inequality than between group (96% and 4%)

20. Table 4.5 Earnings equation using Heckman Procedure and OLS by Sex (log of Earnings as Dependent Variable) Total Population

21. Earnings Literacy significantly and positively affects income
Education is not significant
However, using OLS education is significant and literacy is not significant
Being employed in rural area is significant and sign is negative

22. Table 4.6 Analysis of Inequality by Employment Group: Self-employed

23. Determinants of Inequality
Inequality was measured by deviation from mean income
Self Employed– determinants of inequality include education, literacy, presence of young dependants, gender and location.
Under-6 children significantly affects mothers’ income, given the sharing of time between labour market activities and child care.

24. Table 4.7 Inequality by Employment Group: Wage Earners

25. Determinants of Inequality – wage earners
Wage earners- determinants of inequality include education and divorce (especially for women)
Self Employed– determinants of inequality include education, literacy, presence of young dependants, gender and location.
Under-6 children significantly affects mothers’ income, given the sharing of time between labour market activities and child care.

26. Table 4.8: Labour Supply Equation using Tobit Procedure (Hours supplied as dependent variable)

27. Determinants of labour market participation
Labour market participation was measured by hours of work
Significant determinants include age, education, marriage, divorce and loss of spouse
For married female, marriage affected participation in the labour market significantly though has a negative relationship
Presence of uner-6 children is inversely related to women participation in the labour market

28. Policy Implications/Recommendation
Labour force participation rate is higher among males than females. Need to improve opportunities for females to engage more in income earning activities. In the short run, this can include emphasis on skill acquisition and credit facilities to enhance participation of females in labour market. On the long run, focus could be on female-child education, improved access of women to ownership of assets
Need for social security for children under six to take care of lower mother participation in labour market. In particular day care provision for children to encourage mothers to work on income earning activities.
Income inequality is more pronounced among the paid employee than self employed. Need to continue to address issues of disparity in cash and fringe benefits among the paid employees given the government reform as it affects monetization. Need to address the wage gap between private and public paid employee.

29. Policy Implications/Recommendation
On the average the self employed earn less than paid employee. The need to improve working environment for the self employed. This could include infrastructure provision, (e.g electricity, transportation etc.) and market opportunities. Need for institutions to coordinate commodities and services provided mainly by the self employed. This can enhance quality, ensure access to markets and improve earnings.

30. Policy Implications/Recommendation
Male workers earn higher average income than female workers. Although the study did not control for age and education. The disparity in earnings might be mainly from private informal activities where wage differences exist due to nature of job.
Rural and informal urban workers need incentives to enhance their earning and thus welfare. Creating appropriate institutions to complement market forces would go along way in improving quality of products and market opportunities.

31. Conclusion
☻Labour market is a primary area where inequality should be addressed
☻Structure of the labour market is an important factor in determining welfare
☻inequality is more pronounced in paid employed
☻Inequality was higher among women involved in paid employment
☻ Disparity in labour earnings is a specific factor, which explains inequality among Nigeria workers
