Economics: Some Important Economists and their Theories PART-2

Thomas Malthus:

Thomas Malthus had two major contributions to the modern economic system: the population theory and the theory of market gluts. Thomas Robert Malthus was the first economist to propose a systematic theory of population.  He articulated his views regarding population in his famous book, Essay on the Principle of Population (1798). He stated that population, when unchecked, increases at a geometrical ratio while food production increases only in an arithmetical ratio.

John Meynard Keynes:

John Meynard Keynes revolutionized the economists’ conceptions about economics. He says that the state can stimulate economic growth and restore stability in the economy through expansionary policy like massive spending on infrastructure when demand is low and growth rate is falling. Theories of Keynes were presented in his book :General Theory of Employment, Interest and Money . He is also known as the father of world bank and IMF(International monetary fund)
