Public Administration and Economics – National Minimum Wage in South Africa

Question 1

South Africa’s National Minimum Wage Act (NMWA) has been in force since 2019 and continues to shape the wage landscape for employers across all industries. The legislation sets the statutory floor below which no employee may be paid and requires annual adjustments to ensure that the wage remains relevant considering economic pressures (Polity, 2026).

•   Explain with the aid of a clearly labelled diagram, the impact of the National Minimum Wage when it is set above the equilibrium wage in a perfectly competitive labour market. (50 marks).

In your answer, analyse the effects of the National Minimum Wage on wages, employment, and unemployment, and critically discuss the relevance of this theoretical model for understanding labour market outcomes in South Africa.

Impact of national minimum wage above equilibrium wage in a perfectly competitive labour market

The diagram is included in the appendix section which includes a labour market graph with y-axis showing the wage rate, x-axis showing the quantity of labour, Labour demand is downward sloping whereas labour supply is upward sloping. The equilibrium Wage and equilibrium employment where demand in supply intersect, and the national minimum wage is set above equilibrium wage. At National minimum wage, the labour supplied increases to Qs and the labour demanded decreases to Qd. The gap between the Qs and Qd indicates unemployment.

Impact on wages

The workers that are employed would get a higher rate whereas the low income workers would benefit from improved earnings and purchasing power. The employers face higher labour costs.

Impact on employment

The labour would become expensive which leads to a direct impact on the hiring process of the firm as it would reduce significantly. Some businesses would consider replacing workers with technology, and the employment falls from Qe to Qd.

Impact on unemployment

More people would be ready to work at a higher wage but the employers would hire few of the workers. The difference between the labour supplied and the labour demanded creates unemployment.

Relevance to South Africa

This model is quite reliable to South Africa because the economy faces high employment, and a large number of workers are low skilled. South Africans also represent a major chunk as labour intensive sectors such as agriculture, retail and hospitality. This model has certain limitations such as some employers absorb higher wage costs without reducing employment, and the higher wages would directly contribute towards improved worker productivity and morale.
