Predicting the impact of a national minimum wage: are the general equilibrium models up to the task?
This article analyses whether computable general equilibrium (CGE) models are suitable for projecting the likely consequences of implementing a national minimum wage. Referring to modelling exercises undertaken by the National Treasury and the Development Policy Research Unit (DPRU), it shows that their projection of a strongly negative impact on employment and other macroeconomic indicators is a direct result of the architecture and assumptions of these models. By design these models preclude alternative outcomes; this renders them rather unsuitable as guides to policymaking.
Most contributions to the debate on a national minimum wage adopt a narrow view of labour markets and accept that the structure of the economy will remain essentially as it is. We question both of these assumptions. Further, we argue that a national minimum wage, at a level to be determined through careful research, must be part of a well-designed package of longer-term policy reforms that look beyond the labour market and support employment growth through investment.
