Abstract

Purpose

The primary motive of a minimum wage policy is to provide a wage floor for poorly paid workers and improve their welfare. In Nigeria, real minimum wage declined by 60 per cent between 1974 and 2011, thus reducing the welfare of workers. The wage gap between low skilled and high skilled workers have also widened over the years in favour of the latter. There are concerns that the series of minimum wage increase in Nigeria may not be welfare-enhancing. The paper aims to discuss these issues.

Design/methodology/approach

This study examined the welfare effects of minimum wage increase in Nigeria using a computable general equilibrium model. The model was calibrated using a 2006 Social Accounting Matrix and four sets of scenarios (20, 35, 50 and 140 per cent wage increases), were simulated.

Findings

The findings show that employers substituted other labour categories for minimum wage workers. This increases the wage rates of other labour. The consumer price index also increased as firms partly pass-on increased labour cost to consumers. Generally, the simulations show that minimum wage policies worsen the welfare of its intended beneficiaries, due to negative impact on prices and employment.

Originality/value

This study deviates from existing studies on minimum wage in Nigeria, by providing a proper disaggregation of the labour market that represents the Nigerian economy. In this regard, the informal sector was accommodated and the potential impact of the minimum wage on this sector determined. It also adopted the equivalent variation welfare measure which incorporates price and consumption effects in measuring welfare.
