 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.Much post-Keynesian research is published in the "Review of Keynesian Economics" (ROKE), the "Journal of Post Keynesian Economics" (founded by Sidney Weintraub and Paul Davidson), the "Cambridge Journal of Economics", the "Review of Political Economy", and the "Journal of Economic Issues" (JEI).There is also a United Kingdom academic association, the Post Keynesian Economics Society (PKES).
