Although the term has been used (and abused) to describe many things over the years, six principal tenets seem central to Keynesianism. The Neo-Keynesians worked on reconciling Keynes’ insights with macroeconomic modelling, the New Keynesians on microfoundation-consistent modelling that produced the results he described, while post-Keynesians reject many of the starting assumptions of orthodox economics in favour of different, Keynes-inspired assumptions. ‘New Classical’ economists are more likely to accept ideas of rigidities in prices and wages.
