      John Maynard Keynes

      He was an English economist, financier, and journalist who worked towards fundamental changes in the theory of macroeconomics and government policies. Alfred Marshall influenced him.

      Keynes started his career as a civil servant in Whitehall at India Office and wrote his first book, "Indian Currency and Finance," in 1913. His outstanding contribution made him appointed to the Royal Commission on Indian Currency and Finance.

      Keynes worked in the Treasury for the British government during the First World War in 1915. After resigning, he wrote another masterpiece named "The Economic Consequences of Power" in 1919.


      Some of the books he published

      • A Treatise on Probability
      • A Revision of the Treaty 
      • A Tract on Monetary Reforms
      • Economic Consequences of Mr. Churchill
      • The General Theory of Employment, Interest, and Money

      As the founder of Keynesian Economics, he gave his perception of economic recession and the role of government in curbing the same. He emphasized the active role of government by influencing spending and taxes.

      The idea of the former book was to explain the relationship between the level of employment and aggregate demand. In the latter, he introduced the concept of full employment and the government's role in maintaining it.

      Keynes led a revolution in economic thinking during the Great Depression. He also designed the international economic institutions established after the second world war.

      He is "Britain's most famous 20th-century economist" according to The Economist and a part of the "Most Important People of the Century" given by Time magazine. 

      Friedrich Von Hayek

      Hayek was an Austrian economist, philosopher, and legal theorist. He was a defender of classical liberalism and free-market capitalism. Also, he was the most prominent critic of the socialist consensus.


      He received the Nobel Memorial Prize in Economic Sciences in 1974 for his work on money, economic fluctuation, and interdependence of social, economic, and institutional phenomena. 

      People determined their plans using his theory on how the changing prices communicate information. Between 1940 and 1943, he gave the world of economics his book "The Road to Serfdom."

      He was appointed to the Order of the Companions of Honor, on the advice of Prime Minister Margaret Thatcher, by Queen Elizabeth II in 1984 for his services in studying economics. He was also awarded the Hanns Schleyer Prize.

      The Presidential Medal of Freedom by President George H.W. Bush in 1991 was given to him, and in 2011 his article "The use of knowledge in society" was chosen among the top twenty articles during its first hundred years.

      Ludwig Von Mises

      He was an Austrian school economist, logician, historian, and sociologist who wrote extensively on classical liberalism and its societal contribution. He was one of the most influential political and economic thinkers of the 20th century.


      In 1912, his best work was published with the title "The Theory of Money and Credit," which was also used as a textbook for money and banking. The extension to it included marginal utility theory to money.

      The general conceptual foundation he adopted was praxeology and has also set a methodological approach to economics. His book, "Human Action," used praxeology, a distinctive methodology to study human behavior.
      He was the founder of the Austrian Institute for Business Cycle in 1926 and also gave business cycle theory. The book highlights the elevation of unemployment of resources and labor, hyperinflation, and a crack-up boom.

      Mises also served as a front office in the War Department of Austria during the first world war. In addition, he was a strong opponent of Nazism and Austrian Chancellor Engelbert Dollfuss's economic advisor.

      He was an opponent of government intervention in economic matters and also adhered to the principle of laissez-faire. Instead, he focused on the free market economy as the most effective tool for producing and distributing goods and services.

      Milton Friedman

      Milton Friedman was an American economist, educator, and statistician. He insisted that studying economics enables one to understand the working of the real world and separates it from being a mathematical game.

      In 1956, he promoted the changes in the money supply in his book "Studies in the Quantity of Money." He established the relationship between money supply and real economic activities in the short run and price level in the long run.

      In 1957, he wrote "A Theory of the Consumption Function" and articulated the permanent income hypothesis, savings decisions, and household consumption. The hypothesis explained questions arising in empirical data.

      He is remembered the most for his contribution to monetary economics and is known as the founder of monetarism. He countered the business cycle by emphasizing the use of the government-sponsored policy.


      He has raised questions on many constructs of Keynesian economics in his work. In 1976 he was awarded the Nobel Prize in Economics and later, in 1977, became a member of the Hoover Institution of War, Revolution, and Peace.

      Over time, he became an articulate spokesman for free societies and free markets—his ideas regarding monetary policy, privatization, taxation, and deregulation significantly impacted government policies.

      He has covered many public policy issues and economic topics in his career. The Economist named him "the most influential economist of the second half of the 20th century".

      He served on various royal commissions, including the 1919 Royal commission on income tax and the Cunliffe Committee. 

      His famous works are "The Pigou Effect," which highlights the stimulation of employment and output caused by an increase in consumption due to government actions, and "The Economics of Welfare."

      He gave three measures to describe income.

      1. In money terms: the maximum amount spent keeping the capital value of prospective receipts during a period.
      2. Market price neutral: the maximum amount spent in a week, ensuring the ability to spend the same amount the next week.
