thesis. Keynes lived from June 5, 1883 to April 21, 1946. He was a British economist, journalist, and financier, best known for his revolutionary economic theories (Keynesian economics) on the causes of unemployment and level of national income. Samuelson makes his mathematical formulations in the context of neo-Keynesian economic theory.Another influence of Samuelson is his own life.
