Circular Flow of Income in Four Sector Economy

3. The Four-Sector Economy: The circular flow model in four sector economy provides a realistic picture of the circular flow in an economy. The four sector economy comprises of: a) Household b) Firms c) Government d) Foreign Sector Here, there are two important components: a. Export: Export is referring to as an injection into the circular flow that consists of payment receives for goods and services sold to the rest of the world. b.

In this model, each sector has dual roles to play in the economy; while one s

Circular Flow of Income in Three Sector Economy

2. The Three-Sector Economy : In the circular flow model of three sector economy, government intervention has also been accounted for.

The circular flow of income is the model of the economy in which the major exchanges are represented as flows of money, goods and services etc. between economic agents. The flows of money and goods exchanged in a closed circuit correspond in value, but run in the opposite direction. The circular flow of income can be described in three types of economies. They are: 1. The Two-Sector Economy 2. The Three-Sector Economy 3. The Four-Sector Economy (Open Economy) 1.

WHAT IS GDP? Definition and Example

Gross Domestic Product (GDP) is the market value of all final goods and services produced within a country in a given period of time. GDP measures two things at once; the total income of everyone in the economy and the total expenditure on the economy’s output of goods and services. The reason that GDP can measure both total income and total expenditure is that these two things are really the same. For an economy, as a whole the income must equal to its expenditure. The income must be equal to its expenditure because every transaction has two parties; a buyer and a seller. Every dollar of spending by some buyer is a dollar of income for some seller. For example, if person A buys some goods on the cost of $20, then that $20 is his spending (expenditure). On the other hand, the $20, which the buyer has given to seller in exchange of some goods, is the income of the seller. Thus, the transaction contributes equally to the economy’s income and to its expenditure. GDP whethe
