Besides, the government also borrows money from the financial market so it can meet its expenditures. The government sector summarizes the actions of all levels of government in an economy. Governments tax their citizens, pay transfers to them, and purchase goods from the firm sector of the economy. The amount that the government collects in taxes need not equal the amount that it pays out for government purchases and transfers. If the government spends more than it gathers in taxes, then it must borrow from the financial markets to make up the shortfall.

  • For instance, when households decide to save a portion of their income instead of spending it on goods and services, this money is removed from circulation, causing a leakage.
  • Government borrowing is sometimes referred to as the government budget deficit.
  • Technically speaking, so long as lending is equal to borrowing (i.e., leakages are equal to injections), the circular flow will continue indefinitely.
  • 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.
  • The primary types of leakages include savings (S), taxes (T), and imports (M).
  • It was believed by classical economists that financial market provides a mechanism which coordinates the savings of households and the investment expenditure, by the firms.

Firms receive revenue from households, government and the foreign sector for sale of their goods and services. Households provide factor services to firms, government and foreign sector. The residents then use their earnings to buy delicious bread and pastries from the bakery.

The Circular Flow of Income through Various Sectors of an Economy

In our above analysis of money flow, we have ignored the existence of government for the sake of making our circular flow model simple. This is quite unrealistic because government absorbs a good part of the incomes earned by households. On the other hand, if the equality between planned savings and planned investment is disturbed by the increase in investment demand, the result will be increase in income, output and employment. When households save, their expenditure on goods and services will decline to that extent and as a result money flow to the busi­ness firms will contract.

  • From the government’s perspective, both households and business pay taxes.
  • This may be considered as the firms selling the goods to themselves to add to their inventories.
  • The money flow transfers money and other forms of credit in the economy.

Goods and services produced within the domestic territory which are sold to the foreigners are called exports. 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 flow of goods and services and factors payments between firms and households reflects the circular flow of money in an economy. Injections in the circular flow of income refer to external factors that increase the flow of money within an economy.

Four-Sector Model: Incorporating Foreign Trade

Households earn money through wages and salaries, then spend that money on goods and services provided by businesses, ensuring a continuous flow of funds that keeps the economy thriving. In a five-sector model, cash flow from the financial sector is added. This includes banks and other institutes that provide cash flow via lending services. Some circular flow models also outline investor activity, as cashflow from entrepreneurs and investors may represent an inflow to businesses while net profits from the company represent an outflow. The four sector model is formed by adding the foreign sector to the three models.

Chapter 4: Determination of Income and Employment

The three-sector model adds the government sector to the two-sector model.[17][18] Thus, the three-sector model includes (1) households, (2) firms, and (3) government. The government sector consists of the economic activities of local, state and federal governments. Flows from households and firms to government are in the form of taxes.

Circular Flow of Income and Expenditure-Four Sector Economy

At the same time, both the bubble tea shop and grocery store employ people from the households, paying them wages for their labor. The households then use their income to purchase goods and services from businesses, such as the bubble tea shop and the grocery store. In a two-sector model, circular flow models start with the household sector that engages in consumption spending (C).

Household Sector

So, firms borrow money from the financial markets to maintain the flow of money. When we lend to other countries, we acquire their assets, so each year we get income from those assets. When we borrow from other countries, they acquire our assets, so we pay them income on those assets. Those income flows are added to the trade surplus/deficit to give the current account of the economy.

Money flows from producers to workers as wages and flows back to producers as payment for products. 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. To explain this we have to introduce saving and investment in the analysis of circular flow of income. 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 the Circular Flow of Income?

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. A change in one sector may critically change the rest of the circular flow model.
