In some cases, logistics-related businesses may choose to go beyond transport and storage and help with the disabling and processing of returned goods and returning them to market. The idea of the circular flow was already present in the work of economist Richard Cantillon. In sum each fundamental unit of the economy, whether household or firm, acts both as producer and consumer.


Circular chains could reduce our total material footprint by 28% by 2032, according to the Circularity Gap. For this purpose, then private investment by business firms must be less than the savings of the households. Thus Government borrowing reduces private investment in the economy. In other words, Government borrowing crowds out private investment. Let us make in-depth study of the circular flow of income in two sector, three sector and four sector economy. The circular flow of income is a simple model to explain basic economic transactions.

Types of models

If businesses decided to produce less, it would lead to a reduction in household spending and cause a decrease in GDP. Or, if households decided to spend less, it would lead to a reduction in business production, also causing a decrease in GDP. Analyzing the circular flow model and its current impact on GDP can help governments and central banks adjust monetary and fiscal policy to improve an economy. Based on the above assumptions, the four-sector circular flow model can be further explained with help of the following diagram.

On the other hand when a country imports goods from outside, it has to expend its foreign exchange in paying for these goods. So long as a country earns more foreign exchange than it needs to pay out , it can be said to have a favourable Balance of Payments. Thecircular flow of economic activityis a model showing the basic economic relationships within a marketeconomy. It illustrates the balance between injections and leakages in our economy. Half of the model includes injections, and half of the model includes leakages. The circular flow model shows where money goes and what it’s exchanged for.

Not all products go to households within the economy; some products are exported to other countries, leaving the circular flow. Likewise, businesses from outside the economy sell their products to households within the economy in the form of imports. The model also does not account for situations in which the levels of supply and demand fluctuate. Prices may be changed for reasons other than the natural functioning of market forces. For example, if consumer tastes shift, levels of demand would change, causing prices to change. This could result in inefficiencies in the economy that interrupt the circular flow.

Types of Circular Flow of Income

The idea of circular flow was first introduced by economist Richard Cantillon in the 18th century and then progressively developed by Quesnay, Marx, Keynes, and many other economists. Representation of reciprocal financial and real flows between economic factors. Also in some cases, if the net tax revenue is higher than the government expenditure, the government reduces the public debt and funds the capital market. Foreign Sector includes the import and export of goods and services. Aggregate demand is a measurement of the total amount of demand for all finished goods and services produced in an economy. Macroeconomics studies an overall economy or market system, its behaviors, the factors that drive it, and how to improve its performance.

For example, when you buy coal, it is an intermediate good because it is used to produce electricity. The calculation of national income takes into account only final goods. It does this by looking at how much money is spent on each type of good.

Pushing ahead with circular economy supply chains

The purpose of a theory is to take a complex, real-world issue and simplify it down to its essentials. If done well, this enables the analyst to understand the issue and any problems with it. A good theory is simple enough to be understood, while complex enough to capture the key features of the object or situation being studied. Economists carry a set of theories in their heads like a carpenter carries around a toolkit. When they see an economic issue or problem, they go through the theories they know to see if they can find one that fits. Then they use the theory to derive insights about the issue or problem.

  • Value is defined as an item that has a worth that can be expressed in dollars and cents.
  • The money flow from households and business firms to the government is labelled as tax payments in Fig.
  • The better qualified, competent, and motivated a workforce is, the more productive it can be.
  • Marx distinguishes between “simple reproduction” and “expanded reproduction”.
  • The idea that income and goods flow in a circular fashion between businesses and households dates to the earliest economic theorists.
  • A labour market is the input market in which households supply work for wages to firms that demand labour.

In the former case, no the state of economy is circular flow of economic activity growth occurs, while in the latter case, more is produced than is needed to maintain the economy at the given level, making economic growth possible. It indicates the movement of money from different economic sectors in terms of factor payments for availing factor services. This equation shows equilibrium in the circular flow of income and expenditure. The foreign sector receives income from the business sector in return for the goods and services imported by the latter.

Economics for Everyone: Circular Flow – Basic framework of an Economy

Instead, it describes the current position of an economy regarding how its inflows and outflows are used. For example, if a country realizes it has deficient national income, it may choose to reduce its imports and scale back certain government programs. The circular flow model demonstrates how money moves through society.

Leakages and Injections play a vital role in the operation of the circulation flow model. The presence of leakages and injections in the circular flow model makes it inconsistent. Leakage refers to the divergence of income or capital from the economic circulation and injection refers to the addition of income and capital into the circular flow model.

Non renewable resources such as oil, coal etc once used will never be replaced. Renewable resources can be used and replaced and is not depleted with use. Also, we don’t spend all the money we receive, but will save some in banks. We’ve updated our privacy policy so that we are compliant with changing global privacy regulations and to provide you with insight into the limited ways in which we use your data. Strictly speaking, a theory is a more abstract representation, while a model is a more applied or empirical representation.

On the other hand, taxes on business firms tend to reduce their investment and production. The government offsets these leakages by making purchases from the business sector and buying services of the household sector equal to the amount of taxes. In this way, the circular flows of income and expenditure remain in equilibrium.

In a nutshell, the circular flow of income diagram represents the flow of money and receipt of goods, services and factor services between business firms and households sectors in a two-sector economy. Notably, the economic activities are free from government intervention and it is a closed economy model. When households and firms borrow savings, they constitute injections.

In this model we see that business and household sectors are the principals in the circular flow of real items and money—that takes place in the resource and product markets. In other words, business sector do not buy all the economic resources directly from the households; nor do the households buy goods and services directly from business sector. Starting from the resource market household sector supplies economic resources to satisfy the demand of business sector .

In a four-sector model, money also flows into the circle through exports , which bring in cash from international buyers from the foreign sector. By extension, this indicates that the two-sector or three-sector models are domestic activity only. The foreign sector is different from the domestic sector as there may be administrative inefficiencies that result in lost cash flow due to import taxes, duties, or fees. Therefore, injections refer to the addition of income and resources into the circular flow model.

The concept the circular flow of income is a simplification which attempts to illustrate the flow of money and goods from households to business enterprise and back to households. Consider a circular flow model involving Apple employees and Apple product consumers. In this example, we’ll also include the government to form a three-sector circular flow model. By combining these two parts, we will get the continuous circular flow of income and expenditure in a two-sector economy. The flow of goods and services as well as factors between household, business, government, and foreign sectors.

In the present time of globalization, economies of the world are being increasingly opened and interconnected. When domestic business firms export goods and services to foreign markets, injections are made into the circular flow model. On the other side, if the national businesses or the government imports from the overseas corporations and firms, leakage appears in the circular flow model. Figure 11 shows that taxes flow out of the household and business sectors and go to the government. The government purchases goods from firms and also factors of production from households. Thus government purchases of goods and services are an injection in the circular flow and taxes are leakages in the circular flow.
