Whilst the latter has a greater abundance of originality, the former has a greater clarity of insight and formal expression. Don Patinkin states his theory of the labour market and corresponding notion of the full employment equilibrium in just three pages of Money, Interest and Prices (in the 1965 edn. pp. 127–30). These pages deserve great attention: they state the labour market model that became the standard foundation for the aggregate supply curve in the aggregate demand/aggregate supply (AD/AS) model.
