Economics has been shaped by influential thinkers whose theories have guided governments, businesses, and policymakers. Adam Smith's 'The Wealth of Nations' established the foundations of market economics. Read more
Who is called father of economics?
EasyAdam Smith, an 18th-century Scottish philosopher and economist, is widely regarded as the "Father of Economics." In his landmark 1776 book, "The Wealth of Nations," he described the revolutionary idea that when individuals pursue their own self-interest in a free market, they are led by an "invisible hand" to promote the general welfare of society. His work laid the foundation for modern free-market capitalism.
Smith was famously absent-minded; he was once seen walking 15 miles in his nightgown while deep in thought, and he often talked to himself in the streets of Edinburgh, oblivious to the people around him.
Who proposed Keynesian economics?
MediumJohn Maynard Keynes was a British economist whose ideas fundamentally changed the way governments manage their economies. He proposed "Keynesian Economics," arguing that during a recession, the government should borrow money and spend it to create demand and jobs, even if it results in a budget deficit.
Keynes was also a brilliant investor; while he lost much of his wealth in the 1929 stock market crash, he changed his strategy and eventually grew the endowment of King's College, Cambridge, from ?30,000 to over ?380,000 before his death.
Which economist is associated with the 'Invisible Hand'?
MediumAdam Smith is the economist associated with the "invisible hand" concept. It describes the unintended social benefits of an individual's self-interested actions-by trying to make a profit for themselves, businesses naturally end up providing the goods and services that people want.
Despite how famous the term is today, Smith only used the phrase "invisible hand" three times in all of his published works!
What is 'Keynesian Economics'?
HardKeynesian Economics is a theory developed by John Maynard Keynes during the 1930s. It argues that during a recession, the "Invisible Hand" of the free market is too slow, and the government must step in with spending to boost demand.
Keynes' ideas were so influential that President Richard Nixon once famously declared, "We are all Keynesians now!"
What is the 'Invisible Hand'?
MediumThe "Invisible Hand" is a metaphor introduced by Adam Smith to describe the unintended social benefits of an individual's self-interested actions. By trying to maximize their own profit, a business owner ends up providing the best goods at the lowest prices, which benefits all of society.
Smith only used this specific phrase three times in his massive body of work, yet it became the most famous concept in all of economics!
What is 'Pareto Efficiency'?
HardPareto Efficiency is an economic state where resources are allocated in the most efficient manner, such that it is impossible to make any one individual better off without making at least one individual worse off.
It is named after Vilfredo Pareto, an Italian engineer and economist who also discovered the "80/20 Rule" (that 80% of consequences come from 20% of causes)!
Which economist is known for the 'Population Theory'?
HardThomas Malthus is known for his "Malthusian Theory of Population." In 1798, he argued that while food production increases linearly (1, 2, 3...), human population increases exponentially (1, 2, 4, 8...). He predicted that humanity would eventually run out of food, leading to mass starvation.
Malthus failed to predict the Industrial Revolution and modern farming techniques, which have allowed food production to keep up with a massive global population!
What is 'Game Theory'?
HardGame Theory is the study of mathematical models of strategic interaction among rational decision-makers. It is used to predict what will happen when two or more people have to make choices that affect each other.
The "Prisoner's Dilemma" is the most famous example of game theory, showing why two rational people might not cooperate even if it's in their best interest to do so!
Who wrote Wealth of Nations?
HardAdam Smith wrote the "Wealth of Nations" (published in 1776), which is considered the first modern work of economics. In it, he argued against the old system of "mercantilism" (where countries tried to hoard gold) and instead argued that a nation's wealth comes from the productivity of its people and the freedom of its markets.
The book was published in the same year as the American Declaration of Independence. Many historians believe that the ideas in Smith's book helped shape the economic system of the newly formed United States, promoting free trade over government-controlled monopolies.
