Keynes works versus Fischer's work

Keynes advocated for the formulation of monetary and fiscal policies that mitigate the effects caused by the great economic recession. Keynes advocated for full employment and government intervention. Fisher's developed an economic equation that reflects real nominal interest rates and the importance of money supply on the nominal interest rate. Leeth Isharc believes in the economics of monetary equilibrium and started his career as interest rates exotics. He is more interested in hedge funds and, therefore, strongly advocates Fischer's equation and works since they were more focused on interest rates rather than monetary policies as a whole.
