The article discusses the effect of the national minimum wage (NMW) in Great Britain on pay levels and pay dispersion vary with different theories of wages. A review of main theories of wages proposed by leading economists suggests that effects are less determinate than is often thought and that they depend on the role of pay within the motivational structure of firms. An alternative view is presented that examines the dual role of wages. The article also discusses monopsony models and efficiency wage theory.
