Historian Robert Skidelsky argues that the post-Keynesian school has remained closest to the spirit of Keynes' original work. It is a heterodox approach to economics.


Introduction

The term "post-Keynesian" was first used to refer to a distinct school of economic thought by Eichner and Kregel (1975) and by the establishment of the ''Journal of Post Keynesian Economics'' in 1978. Prior to 1975, and occasionally in more recent work, ''post-Keynesian'' could simply mean economics carried out after 1936, the date of Keynes's ''General Theory''. Post-Keynesian economists are united in maintaining that Keynes' theory is seriously misrepresented by the two other principal Keynesian schools: neo-Keynesian economics, which was orthodox in the 1950s and 60s, and new Keynesian economics, which together with various strands of
neoclassical economics Neoclassical economics is an approach to economics in which the production, consumption and valuation (pricing) of goods and services are observed as driven by the supply and demand model. According to this line of thought, the value of a good ...
has been dominant in mainstream macroeconomics since the 1980s. Post-Keynesian economics can be seen as an attempt to rebuild economic theory in the light of Keynes' ideas and insights. However, even in the early years, post-Keynesians such as Joan Robinson sought to distance themselves from Keynes, and much current post-Keynesian thought cannot be found in Keynes. Some post-Keynesians took a more progressive view than Keynes himself, with greater emphases on worker-friendly policies and redistribution. Robinson, Paul Davidson and Hyman Minsky emphasized the effects on the economy of practical differences between different types of investments, in contrast to Keynes' more abstract treatment. The theoretical foundation of post-Keynesian economics is the principle of effective demand, that demand matters in the long as well as the short run, so that a competitive market economy has no natural or automatic tendency towards full employment. Contrary to the views of new Keynesian economists working in the neoclassical tradition, post-Keynesians do not accept that the theoretical basis of the market's failure to provide full employment is rigid or sticky prices or wages. Post-Keynesians typically reject the IS–LM model of John Hicks, which is very influential in neo-Keynesian economics, because they argue endogenous bank lending to be more significant than central banks' money supply for the interest rate. The contribution of post-Keynesian economics has extended beyond the theory of aggregate employment to theories of income distribution, growth, trade and development in which money demand plays a key role, whereas in neoclassical economics these are determined by the forces of technology, preferences and endowment. In the field of monetary theory, post-Keynesian economists were among the first to emphasise that money supply responds to the demand for bank credit, so that a

cannot control the quantity of money, but only manage the interest rate by managing the quantity of monetary reserves. This view has largely been incorporated into mainstream economics and

, which now targets the interest rate as an instrument, rather than attempting to accurately control the quantity of money. In the field of finance, Hyman Minsky put forward a theory of financial crisis based on financial fragility, which has received renewed attention.


Main features

In 2009 Marc Lavoie listed the main features of post-Keynesian economics: * Effective demand * Historical and dynamic time He also lists 5 auxiliary features: * The possible negative impact of flexible prices * The monetary production of the economy * Fundamental uncertainty * Relevant and contemporary microeconomics * Pluralism of theories and methods


Strands

There are a number of strands to post-Keynesian theory with different emphases. Joan Robinson regarded Michał Kalecki's theory of effective demand to be superior to Keynes' theories. Kalecki's theory is based on a class division between workers and capitalists and
imperfect competition In economics, imperfect competition refers to a situation where the characteristics of an economic market do not fulfil all the necessary conditions of a perfectly competitive market. Imperfect competition will cause market inefficiency when it hap ...
. Robinson also led the critique of the use of aggregate production functions based on homogeneous capital – the Cambridge capital controversy – winning the argument but not the battle. The writings of Piero Sraffa were a significant influence on the post-Keynesian position in this debate, though Sraffa and his

Monetary circuit theory, originally developed in continental Europe, places particular emphasis on the distinctive role of money as means of payment. Each of these strands continues to see further development by later generations of economists. Modern Monetary Theory is a relatively recent offshoot influenced by the macroeconomic modelling of Wynne Godley and Hyman Minsky's ideas on the labour market, as well as chartalism and functional finance.
