Keynesian economics
Multiple schools of economic thought that trace their legacy to Keynes currently exist, the notable ones being neo-Keynesian economics, New Keynesian economics, post-Keynesian economics, and the new neoclassical synthesis. Keynes's biographer Robert Skidelsky writes that the post-Keynesian school has remained closest to the spirit of Keynes's work in following his monetary theory and rejecting the neutrality of money. Today these ideas, regardless of provenance, are referred to in academia under the rubric of "Keynesian economics", due to Keynes's role in consolidating, elaborating, and popularizing them.
