Marxism and Keynesianism is a method of understanding and comparing the works of influential economists John Maynard Keynes and Karl Marx.Both men's works has fostered respective schools of economic thought (Marxian economics and Keynesian economics) that have had significant influence in various academic circles as well as in influencing government policy of various states.
Keynesian economics has developed from the work of John Maynard Keynes and focused on macroeconomics in the short-run, particularly the rigidities caused when prices are fixed. It has two successors.

Formally Keynes writes the multiplier as k=1/S'(Y).
Monetarism was particularly influential in the early 1980s, but fell out of favor when central banks found the results disappointing when trying to target money supply instead of interest rates as monetarists recommended, concluding that the relationships between money growth, inflation and real GDP growth are too unstable to be useful in ...
Ultimately, the differences between new classical macroeconomics and New Keynesian economics were resolved in the new neoclassical synthesis of the 1990s, which forms the basis of mainstream economics today, [2] [3] [4] and the Keynesian stress on the importance of centralized coordination of macroeconomic policies (e.g., monetary and fiscal ...
