5 Nobel Prize-Winning Economic Theories You Should Know About
The Public Choice Theory
- James M. Buchanan's work within Public Choice earned him the Nobel Prize in Economic Science in 1986.
- This theory shows that contrary to the conventional wisdom that public-sector actors act in the public's best interests, politicians and bureaucrats tend to act in self-interest, just like private-sector actors.
- Using these insights, we can better understand the incentives that motivate political actors and better predict the results of political decision-making, then design fixed rules that will lead to better outcomes.

Microeconomics: Comparative Advantage
The law of comparative advantage was first mentioned in 1817 by English economist David Ricardo.
A company has a comparative advantage when it is able to provide a good or service at
Opportunity Cost
An opportunity cost is the potential ‘alternative’ or benefit that is forfeited when one chooses a particular option.
The other, foregone option, if it is lower than other companies, is the key factor in this trade-off.
Skills: Diversity And Specialization
Comparative advantage is also measured by the salary yardstick, and how much a person’s time, skills and core skill sets are worth.
Example: Michael Jordan is a skilled basketball player, and is very tall. If he wants, he could paint his own house by himself and do it quickly due to his height. But as he is also a skilled sportsperson, he could earn much more in that time, and probably hire someone else to paint his house, even if the hired painter (who has a comparative advantage due to his specialization of painting houses) takes more time to do it.
A financial crisis
A financial crisis is often associated with a panic or a bank run where investors sell off assets or withdraw money from savings accounts.

Causes of a financial crisis
Generally, a crisis is caused if institutions or assets are overvalued, and can be worsened by panic and herd-like investor behaviour.
Contributing factors include systemic failures, unexpected or uncontrollable human behaviour, regulatory absence or failures, or contagions that is like a virus that spread from one institution or country to the next. If left unchecked, an economic crisis can cause a recession or depression.
Financial crisis examples
- The Stock Crash of 1929. On Oct. 24, 1929, share prices collapsed after a period of wild speculation and borrowing to buy shares. It led to the Great Depression, which was felt worldwide. One trigger of the crash was a drastic oversupply of commodity crops, which led to a steep decline in prices.
- The 20007-2008 Global Financial Crisis. This was the worst economic disaster since the Stock Market Crash of 1929. It started with a subprime mortgage lending crisis in 2007. Then it moved into a global banking crisis with the failure of investment bank Lehman Brothers in September 2008.
Marginal Benefit vs. Marginal Cost
Marginal benefit and marginal cost are two measures of how the cost or value of a product changes.
- The marginal benefit is a measurement from the consumer
Marginal Benefit
A marginal benefit change in a consumer's advantage if they use an additional unit of a good or service.
A marginal benefit usually declines as consumption increases. For example, the consumer may buy one ring for $100, but only willing to buy another if the second ring is $50. The consumer's marginal benefit reduces from $100 to $50 from the first to the second good.
Marginal Cost
Producers consider marginal cost, which is the small but measurable change in the expense to the business if it produces one additional unit.
In producing a product, efficiency in productivity can result in making more products in the same amount of time. The cost of raw materials may also go down if it is purchased in bulk, therefore, decreasing the marginal cost.
