Gross Domestic Product

Gross domestic product (GDP) is a measure of the market value of all final goods and services produced in a period. It is also the sum of the value added at each stage of production by all industries within a country. GDP can be expressed in nominal or real terms. Nominal GDP values output in current prices, while real GDP values output adjusted for inflation.

In the United States, GDP is measured and reported by the Bureau of Economic Analysis (BEA). The BEA releases quarterly estimates of GDP growth in both nominal and real terms. These estimates are followed closely by economists and policymakers as they provide insights into the health of the economy.

While GDP is a widely used metric, it has its limitations. One criticism is that it does not account for unpaid work, such as child care or housework. Another is that it does not consider the distribution of income across households. As such, it may not provide an accurate picture of economic well-being for all members of society.

Keynesian Theory

In macroeconomics, Keynesian theory is an economic theory that attributes fluctuations in aggregate demand to changes in autonomous spending and concludes that active government policy is needed to stabilize output over the business cycle.

The basis for Keynesian theory is the assumption that prices, wages, and interest rates do not adjust quickly or smoothly to changes in economic conditions. This sticky prices assumption implies that there is a lag between when an economic event occurs and when its full effects are felt in the economy. For example, if aggregate demand falls, it will take time for prices, wages, and interest rates to adjust downward. In the meantime, output will also fall. The goal of Keynesian policy is to smooth out these fluctuations and reduce the severity of the business cycle.

Keynesian theory was developed by British economist John Maynard Keynes during the 1930s. It was originally presented in his book The General Theory of Employment, Interest, and Money (1936).


In macroeconomics, stagflation is a situation in which the inflation rate is high and the economic growth rate is low. This combination can lead to lower living standards and higher unemployment.


Inflation is when the overall prices of goods and services in an economy rise. This usually happens when the demand for these goods and services outpaces the supply, leading businesses to raise their prices to keep up with consumer demand. Inflation can also be caused by an increase in the money supply, which can lead to higher prices as people have more money to spend on goods and services.

Inflation can have both positive and negative effects on an economy. On one hand, it can lead to higher wages as businesses try to keep up with rising prices. This can help boost economic growth and standard of living. On the other hand, inflation can also lead to higher costs of living as people have to spend more money on essentials like food and shelter. It can also lead to lower savings rates, as people will tend to spend their money rather than save it when prices are constantly rising.

Policymakers typically use monetary policy tools to target a specific rate of inflation. For example, if policymakers want to achieve 2% inflation, they may use tools like interest rates and quantitative easing (printing money) to increase the money supply and spur economic growth.


Deflation is a decrease in the price level of goods and services. This is the opposite of inflation, which is an increase in the price level. Deflation can be caused by a decrease in money supply or a decrease in demand for goods and services.

Supply Side Economics

Supply-side economics is a macroeconomic theory that stresses the importance of increasing the supply of goods and services in order to promote economic growth. The theory is often associated with laissez-faire or free-market approaches to economics.

The key elements of supply-side economics include:

Lowering taxes and regulations to encourage businesses to invest and expand.

Reducing government spending to free up resources for the private sector.

Encouraging workers to increase their productivity through training and education programs.

Supporters of supply-side economics argue that it is a more effective way to promote economic growth than demand-side policies, such as Keynesian fiscal policy. They also point out that countries with lower tax rates and less regulations tend to grow faster than those with higher taxes and more regulations.

Critics of supply-side economics argue that it leads to income inequality and benefits only the wealthy. They also argue that it fails to address the underlying problems of an economy, such as weak demand or structural unemployment.

Market Failure

Market failure is the inability of a market to efficiently allocate resources. This can be due to a variety of factors, including imperfect information, externalities, and public goods. When a market fails, it can lead to sub-optimal outcomes for both buyers and sellers.

There are a number of different types of market failures that can occur. One type is known as informational asymmetry, which occurs when one party in a transaction has more or better information than the other party. This can lead to problems such as moral hazard, where one party takes on more risk than they would if they had complete information.

Another type of market failure is externalities, which are costs or benefits that are not borne by the parties involved in the transaction. For example, pollution from a factory could be considered an externality. If the polluting company does not have to pay for the cleanup or health costs associated with the pollution, they may be less likely to take steps to reduce their pollution levels.

Public goods are another type of market failure. These are goods or services that are non-rivalrous and non-excludable – meaning that one person’s consumption does not reduce availability for others, and it is impossible to exclude non-payers from enjoying the good or service. National defense is typically considered a public good, since everyone benefits from it but it is impossible to exclude anyone from its benefits.


Monetarism is an economic theory that focuses on the role of money in the economy. Monetarists believe that money is the main driver of economic activity, and that changes in the money supply can have a major impact on inflation and economic growth.

While monetarism has been influential in central banking and macroeconomic policymaking, it has fallen out of favor in recent years. Critics argue that monetarism does not adequately explain the complex relationships between money, credit, and other factors in the economy.

Market Economy

A market economy is one in which the production and distribution of goods and services is determined by the interplay of supply and demand in the marketplace. Market economies are characterized by a high degree of economic freedom, voluntary exchange, and competition.

In a market economy, businesses and households interact in markets to allocate resources and produce and exchange goods and services. The key characteristic of a market economy is that decisions regarding investment, production, and consumption are made by private individuals and firms.

A market economy has several benefits. First, it allows for greater economic freedom than other economic systems. Individuals are free to choose what they want to produce or consume. This leads to a more efficient allocation of resources since people are able to produce what they are best at producing.

Second, market economies promote competition. This encourages firms to be efficient and innovative in order to survive. Third, market economies tend to be more prosperous than other economic systems because they allow for the efficient use of resources. Finally, market economies provide opportunities for people to improve their standard of living through entrepreneurship and hard work.

Market Equilibrium

In economics, the market equilibrium is a state in which the supply and demand for a good or service in a market are equal. The market equilibrium occurs when the quantity of a good or service that buyers are willing and able to buy (demand) equals the quantity of a good or service that sellers are willing and able to sell (supply).

In a market equilibrium, prices reflect the relative values that consumers place on goods and services. For example, if more people want to buy a good than there are willing sellers, then the price of the good will increase. Conversely, if more people want to sell a good than there are willing buyers, then the price of the good will decrease.

The market equilibrium is sometimes also referred to as the "market clearing" because it represents a state in which there is no surplus or shortage of any goods or services. A surplus occurs when there is more of a good or service available than what consumers are willing to buy at the current price. A shortage occurs when there is less of a good or service available than what consumers are willing to pay at the current price.

It is important to note that the market equilibrium is not necessarily static; it can change over time as consumer preferences and technology change.


In conclusion, these are just a few of the macroeconomics terms that you need to know. Of course, there are many more out there, but understanding these ten will give you a good foundation on which to build your knowledge. With a solid understanding of macroeconomics, you'll be able to better navigate the financial world and make sound investment decisions.
