My revised diagram of the subgroups of Post Keynesian economics.
In this version I have included Joseph Steindl and Kurt Rothschild amongst the Kaleckians.
Unfortunately, some nagging doubts still remain:
(1) is there a better way to classify the American Post Keynesians Alfred Eichner and Sidney Weintraub?Update 2
(2) were James E. Meade and E. Austin G. Robinson Post Keynesians or did they basically remain neoclassical synthesis Keynesians?
(3) where should Lorie Tarshis go?
In light of the discussion below, I have updated the chart again.
My final version of the chart (I hope!), with Evsey Domar added to the Early North American Post Keynesians.
