What happens when a previously unregulated labour market is regulated? After the introduction of minimum wages and mandatory employment contracts for domestic workers, wages increased markedly while neither employment nor hours worked declined; some formalisation of working conditions also occurred. All these occurred despite a lack of monitoring and enforcement, suggesting that such actions (often costly) are not essential for regulation to have a significant impact on informal employment conditions, at least in the short run.
Average wages in agriculture have risen substantially in all provinces since the introduction of minimum wages in 2003 - the gap between the actual and the minimum wage has declined significantly. Compliance has been highest in the Western Cape and Gauteng, where average agricultural wages were close to or above the minimum wage even before it was introduced and wages have continued to rise thereafter. Although enforcement appears to have had a limited impact due in part to limited penalties, more effective inspection would be an important way to improve compliance.
