Circular Flow Model Definition and Calculation

An important development was John Maynard Keynes’s 1933 publication of the General Theory of Employment, Interest and Money. Keynes’ assistant Richard Stone further developed the concept for the United Nations (UN) and the Organisation for Economic Co-operation and Development to the systems, which is now used internationally. Furthermore, a significant improvement was made in 1933 by John Maynard Keynes and his assistant, which further developed the concept for the United Nations that is the current model used now.

You also report that there was a recent increase in the price level. As yet, though, you do not know anything about either the causes or the consequences of these events. Measurement of the economy tells you what has happened, but it tells you neither why it happened nor what it means.

In the three-sector model, the government is added to the two-sector model. In this model, money flows from households and businesses to the government in the form of taxes. The government pays back in the form of government expenditures through subsidies, benefit programs, public services, etc.

Figure 6.4 illustrates additional money flows that occur in the open economy when exports and imports also exist in the economy. In our analysis, we assume it is only the business firms of the domestic economy that interact with foreign countries and therefore export and import goods and services. Here we will concentrate on its taxing, spending and borrowing roles. Government purchases goods and services just as households and firms do. Government expenditure takes many forms including spending on capital goods and infrastructure (highways, power, communication), on defence goods, and on education and public health and so on. It will be seen that government purchases of goods and services from firms and households are shown as flow of money spending on goods and services.

Implications of the Circular Flow Model

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. It means that the households spend their entire income on the purchase of goods and services and every firm spends all the receipts from the sale of goods and services to make factor payments. However, it does not happen in the actual world, i.e., households do not spend their entire income on the consumption of goods and services. In the same way, the firms save some part of their receipts for the expansion of business or various other reasons. Besides, the firms also borrow money from outside to finance their expansion plans.

  • We need to know its limitations so we don’t ask the Circular Flow of Income to do too much.
  • In the circular flow model, the value of goods and services produced equals the sum of household consumption, investment by firms, government spending and exports minus imports.
  • The circular flow of income demonstrates how economists calculate national income, or gross domestic product (GDP).
  • Furthermore, a significant improvement was made in 1933 by John Maynard Keynes and his assistant, which further developed the concept for the United Nations that is the current model used now.

Therefore, in case of trade deficit, domestic consumer households and business firms will borrow from abroad to finance their excess of imports over exports. In the open economy there is interaction between countries not only through exports and imports of goods and services but also through borrowing and lending funds or what is also called financial market. These days financial markets around the world have become well integrated. In opposite direction to this, money flows from business firms to the households as factor payments such as wages, rent, interest and profits. The government provides payment for the purchases of goods & services to the business firms and income for the factor of production to the household sector.

Types of models

A certain portion of the company’s profits is given to the government in the form of taxes. In some cases, Apple may benefit from government programs or subsidies, so part of these tax dollars may indirectly benefit Apple. 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.

Firm Sector

In this example, additional sectors (or additional flows) could be added. For example, Apple is an international company that sells goods around the world. Another example is how investors may contribute money into Apple in return for a portion of the company. This example highlights the complexity of the circular flow model as inputs and outputs are continually cycling throughout a systematic economy. The expenditure method of national income calculation is based on the expenditures taking place in the economy. The expenditures that happen in an economy can be done by individuals, households, business enterprises, and the government.

What is Circular Flow of Income?

In other words, the flow of money income will not always continue at a constant level. In year of depression, the circular flow of money income will contract, i.e., will become lesser in volume, and in years of prosperity it will expand, i.e., will become greater in volume. This sector encompasses imports and exports with other nations–international, rather than intranational, trade. Leakage from and injection into the economy takes place as a result of imports and exports of goods.

Earlier, we emphasized that GDP measures the production of an economy. Now we see that GDP is equally a measure of the income of an economy. Again, this reflects the fact that there are two sides to each transaction. We can use the terms income, spending, production, and GDP completely interchangeably. Looking at some basic measurements of the economy has allowed you to be more concrete about the problems in Argentina. You report back to the International Monetary Fund (IMF) team that production has been declining in recent years.

However, households who view the rate of interest as return on savings feel encouraged to save more. Real flows of resources, goods and services have been shown in Fig. In the upper loop of this figure, the resources such as land, capital and entrepreneurial ability flow from households to business firms as indicated by the arrow mark. Withdrawals are leakages from the economy as a result of taxation, spending on imports, and monetary savings. The circular flow of income or circular flow is a model of the economy in which the major exchanges are represented as flows of money, goods and services, etc. between economic agents.

Households receive income from Apple, though part of these funds is given to the government via taxes. The financial market also plays an important role in a three-sector economy, as the government saves a part of their earned income and deposits the same in the financial market. Besides, the government also borrows money from the financial market so it can meet its expenditures. Amongst these questions, the main question is how economies create wealth. In an economy, all factors of production (FoP) undergo a production flow/cycle; in the process of which it generates wealth in the form of making payments to the factor of production, known as factor payments.

Circular flow of income

The linkage between the saving of households and the investment of firms is one of the most important ideas in macroeconomics. The five-sector model adds the financial sector to the four-sector model.[19] Thus, the five-sector model includes (1) households, (2) firms, (3) government, (4) the rest of the world, and (5) the financial sector. The financial sector includes banks and non-bank intermediaries that engage in borrowing (savings from households) and lending (investments in firms).[19] Money facilitates such an exchange smoothly. 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.

When the government is running a deficit, there is a flow of dollars to the government sector from the financial markets. Alternatively, the government may run a surplus, meaning that its revenues from taxation are greater than its spending on purchases and transfers. In this case, the government is saving rather than borrowing, and there is a flow of dollars to the financial markets from the government sector. 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 interchanges between the household, business firm, and government sectors remain the same if a foreign sector is added to the model. The foreign sector is also referred to as the overseas or external sector. The flows in and out of the firm sector of an economy must balance.

This circular flow of money will continue indefinitely week by week and year by year. It may, however, be pointed out that this flow of money income will not always remain the same in volume. 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.
