Economics is the social science that studies how individuals, businesses, and governments allocate scarce resources to satisfy unlimited wants and needs. Read more
Which tax increases with income?
HardA progressive tax is a tax system where the tax rate increases as the amount of taxable income increases. This means that people who earn more money pay a higher percentage of their income in taxes than people who earn less. Most modern income tax systems, including those in the US, UK, and Canada, are progressive.
The highest top income tax rate in US history was a staggering 94% in 1944 and 1945. It was raised to this level to help pay for the massive costs of fighting World War II, though very few people actually ended up paying that top rate.
What is 'Seigniorage'?
HardSeigniorage is the difference between the face value of money, such as a 10 bill or a quarter, and the cost to produce it. For example, if it costs 5 cents to make a 1 bill, the government earns 95 cents in seigniorage.
If the cost of the metal in a coin becomes more than its face value (like some old pennies), the seigniorage becomes negative, and the government actually loses money by making it!
What is 'Zero-sum'?
HardA Zero-sum game is a mathematical representation of a situation in which each participant's gain or loss is exactly balanced by the losses or gains of the other participants. In these situations, the total benefit to all players always adds up to zero. Most competitive sports, like chess or football, are zero-sum because for one person to win, the other must lose.
Economics is generally not a zero-sum game because trade allows both parties to become wealthier at the same time!
What is real GDP adjusted for?
HardReal GDP (Gross Domestic Product) is an inflation-adjusted measure that reflects the value of all goods and services produced by an economy in a given year. By using "constant-dollar" prices from a base year, it removes the effects of price changes (inflation or deflation) to show whether the actual volume of production has increased or decreased.
If you compare Nominal GDP (not adjusted) and Real GDP during periods of high inflation, a country might look like it is growing by 10% or more, while the "Real" growth might actually be zero or negative once price increases are stripped away.
What is 'Cartel'?
HardA cartel is a group of independent market participants (usually companies or countries) who collude with each other in order to improve their profits and dominate the market. They usually do this by fixing prices or limiting supply.
Cartels are illegal in most countries, but international ones (like OPEC) can exist because there is no "global government" to ban them!
What is the 'Lorenz Curve' used for?
HardThe Lorenz Curve is a graphical representation used to show the distribution of income or wealth within a population. The further the curve bows away from a straight 45-degree line, the more unequal the society is.
The "Gini Coefficient" is actually a mathematical measurement of the area between that straight line and the Lorenz Curve!
What is the term for a market with only one buyer?
HardA monopsony is a market structure in which there is only one buyer for a particular good or service. This gives the buyer significant power to dictate prices and terms to the sellers. A classic example is a "company town" where a single factory is the only employer for all the workers in the area.
Many economists argue that giant retail chains can act as "monopsonies" toward their small suppliers, forcing them to accept very low prices!
What is 'Mercantilism'?
HardMercantilism was an economic theory popular in Europe between the 16th and 18th centuries that argued a nation's power depended on its wealth, specifically its gold and silver reserves. It encouraged countries to export as much as possible and import as little as possible to keep wealth within the country. This led to many wars and the rise of colonial empires.
Mercantilism was the dominant system that Adam Smith attacked in his famous book 'The Wealth of Nations!'
What is the term for the total value of goods and services produced by a country's citizens?
HardGross National Product (GNP) is the total value of all finished goods and services produced by a country's citizens and businesses, regardless of where they are located in the world.
While GDP measures what is produced within a country's borders, GNP follows the people-so a Japanese company factory in the US counts towards US GDP but Japanese GNP!
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!"
Which measure includes foreign income?
HardGross National Product (GNP) is the total value of all finished goods and services produced by a country's residents and businesses, regardless of where the production takes place. Unlike GDP, which focuses on production within a country's borders, GNP includes income earned by citizens working abroad and subtracts income earned by foreigners within the country.
For many years, the United States used GNP as its primary measure of economic activity before switching to GDP in 1991 to bring its reporting in line with most other nations and better reflect the activity happening inside the country.
What is a 'Public Good'?
HardA Public Good is a product or service that is "non-excludable" (you can't stop people from using it) and "non-rivalrous" (one person's use doesn't reduce it for others). Classic examples include national defense, street lighting, and clean air.
Public goods often suffer from the "Free Rider Problem," where people use the service without paying for it (e.g., via taxes), which is why the government usually has to provide them!
Which curve shows the tradeoff between inflation and unemployment?
HardThe Phillips Curve is an economic concept developed by A.W. Phillips, stating that inflation and unemployment have a stable and inverse relationship. The theory suggests that with economic growth comes inflation, which in turn should lead to more jobs and less unemployment.
While this relationship held true for decades, the "Stagflation" of the 1970s proved that it is possible to have both high inflation and high unemployment at the same time!
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 Laffer curve related to?
HardThe Laffer Curve is a theoretical relationship between tax rates and the amount of tax revenue collected by a government. It suggests that if tax rates are 0%, the government gets no money, but if tax rates are 100%, people will stop working entirely, so the government also gets no money. Therefore, there must be an "optimal" tax rate in the middle that maximizes revenue.
The curve is named after economist Arthur Laffer, who famously sketched the idea on a cloth napkin during a meeting with White House officials in 1974 to show them why cutting taxes could sometimes actually increase the government's total tax income!
What is 'Gross Profit'?
HardGross Profit is the profit a company makes after deducting the costs associated with making and selling its products (Cost of Goods Sold or COGS). It is calculated as Total Revenue minus COGS. It does not include other expenses like taxes or interest.
Gross profit margin is a great way to see how efficiently a company is producing its core products before the "overhead" costs kick in!
What is 'Hedge Fund'?
HardA Hedge Fund is an investment fund that pools capital from accredited individuals or institutional investors and invests in a variety of assets, often with complex portfolio-construction and risk-management techniques. They are called "hedge" funds because they often take positions that "hedge" against market downturns.
Unlike mutual funds, hedge funds are mostly unregulated and are only open to very wealthy "sophisticated" investors!
What is liquidity trap?
HardA Liquidity Trap is a situation in which interest rates are very low and savings rates are high, rendering monetary policy ineffective. In this state, consumers and investors prefer to hold onto cash (liquidity) rather than investing it, even when the central bank tries to stimulate the economy by increasing the money supply. This often happens when people expect a deflationary event or a war.
The concept was famously introduced by John Maynard Keynes; during a liquidity trap, the central bank's usual tool of lowering interest rates is like "pushing on a string"-it simply has no effect on stimulating the economy.
What is 'Deadweight Loss'?
HardDeadweight Loss is the loss of economic efficiency that occurs when the equilibrium for a good or service is not achieved. This is often caused by market distortions like taxes, subsidies, or price ceilings. It represents value that is lost to both the buyer and the seller.
Economists use deadweight loss to show why "perfectly competitive" markets are usually better for society than markets with high taxes or monopolies!
What is 'Regressive Tax'?
HardA Regressive Tax is a tax applied uniformly, taking a larger percentage of income from low-income earners than from high-income earners. It is in opposition to a progressive tax.
Sales tax is often considered regressive because a poor person and a rich person both pay the same 1 tax on a loaf of bread, but that 1 is a much bigger deal to the poor person!
