The Circular Flow of Income

Residuals from each market enter the capital market as savings, which in turn are invested in firms and the government sector. Technically speaking, so long as lending is equal to borrowing (i.e., leakages are equal to injections), the circular flow will continue indefinitely. However, this job is done by financial institutions in the economy. In the circular flow of income (two-sector economy), there is an exchange of goods and services between the two players i.e., the firms and households, which leads to a certain flow of money in the economy. The firms then make factor payments to households in the form of rent, wages, interest, and profit.

This equation is called the national income identity and is the most fundamental relationship in the national accounts. When the value of leakages EXCEEDS the value of injections, the economy is slowing. More money is being removed (or withdrawn) from the economy than is being pumped into it. As a result, GDP is likely falling, unemployment is on the rise and prices and probably dropping (lower inflation). When the value of injections EQUALS the value of leakages, the economy is in a state of equilibrium.

In the financial sector

1. Households spending money in the product market represents Consumption.
2. In the circular flow of an economy in a two-sector model without the financial market, it is assumed that no savings are made in the economy.
3. Households are consumers of goods and services and the owners of the factors of production (land labour, capital, and enterprise).
4. These factors are the components of a nation’s gross domestic product (GDP) or national income.
5. Injections into the circular flow of income are a result of money borrowed by households and firms from different external sources, like financial institutions.

We simply imagine that households take their savings to financial markets to purchase interest-bearing assets. Some individual households are net borrowers, but, overall, the household sector saves. There is, on net, a flow of dollars from the household sector to the financial sector of an economy. These dollars are then available for firms to borrow to build new factories, install up-to-date equipment, and so on. That is, they are available for investment.The flows in and out of the household sector are discussed in Chapter 27. We can make this idea more precise, using the pizza economy to illustrate.

Why Is It Called a Circular Flow Model?

In a two-sector model, circular flow models start with the household sector that engages in consumption spending (C). Households contribute to an economy by working (giving away time and labor) and by buying products (giving away money). In return, households consume products and utilize government programs. The fifth sector – the financial sector – is added to complete the circular flow model. It includes banks and other institutions that provide borrowing and lending services to the other sectors. Savings and investments are assumed in the five-sector model, which flow from other sectors with residual cash into the financial institutions, then out to the sectors that need money.

Chapter 5: Government Budget and the Economy

After adding in governments, investors, and foreign markets, the circular flow model depicts how cashflow moves money from one sector to the next in a systematic, organized way. Corresponding to the flows of money in the circular flow, there are flows of goods and services among these sectors. For example, the wage income received by consumers is in return for labor services that flow from households to firms. The consumption spending of households is in return for the goods and services that flow from firms to households.

For example, economists may struggle in determining how a 5% increase in unemployment may impact the circular flow model. Though it’s understood that reduced income may lead to less consumption and less tax revenue, a circular flow model may not explain how one change will numerically change other values. From the business perspective, the company exists to create products.

In a three-sector model, government explain circular flow of national income with five sector model sector cash flows are included. The government injects money into the circle through government spending (G) on programs such as Social Security and the National Park Service. It also extracts money from households and businesses by way of taxes.

Four examples are listed below to show the significance of the model. Similarly, some of the goods consumed in our economy are not produced locally. For example, suppose that a US restaurant chain purchases Argentine beef. We could imagine that the restaurant chain hands over US dollars to the Argentine farmers.

1. The circular flow model demonstrates how money moves through society.
2. The economy often moves in a circle as money flows from one sector to another.
3. The business hopes that someone with those skills will eventually see that sign and be willing to provide the required services in exchange for the money (wages) the business is offering.
4. The leakage that the government sector provides is through the collection of revenue through taxes (T) that is provided by households and firms to the government.
5. Flows from households and firms to government are in the form of taxes.
6. In return, households consume products and utilize government programs.

Our global economy is incredibly interconnected, and this is often graphically depicted using the circular flow model. The circular flow model details how resources flow into and out of households, businesses, governments, investors, markets, and foreign entities. This cycle shows how the resources of one sector are used to develop others in a cyclical manner. Ignoring for the moment that the US government and foreign countries are absent from this version, it is important to think about what is actually signified by the product and factor markets.

Households are consumers of goods and services and the owners of the factors of production (land labour, capital, and enterprise). The economy often moves in a circle as money flows from one sector to another. Households spend money and businesses use that money to create new, better products for the households to buy in the future. Meanwhile, the businesses pay households for their time in helping develop those products.
