Circular flow model1/16/2024 ![]() ![]() Four SectorsThe circular flow model illustrates the interaction among the four macroeconomic sectors-household, business, government, and foreign. The income diverting away from consumption and to saving or taxes does not disappear, but is used to finance investment by business sector and purchases by the government sector. In particular, household income can be used for consumption, saving, or taxes. The prime conclusion of the circular flow model is that the overall volume of the circular flow is largely unaffected by the path taken. However, more realistic circular flow models include saving, investment, and investment borrowing enabled by the financial markets taxes and expenditures of the government sector and imports and exports of the foreign sector. The basic model illustrates the interaction between the household and business sectors through the product and resource markets. Diffe rent versions of the model sequentially combined the four sectors-household, business, government, and foreign-and the three markets-product, resource, and financial-into increasingly more comprehensive representations of the economy. The circular flow model is a fundamental representation of macroeconomic activity among the major players in the economy-consumers, producers, government, and the rest of the world. The circular flow model provides a easy way of getting the "big picture" and of seeing how the key parts of the macroeconomy fit together. In particular, the circular flow is a model of the continuous production and consumption interaction among the four major sectors of the macroeconomy-household, business, government, and foreign-using the three macroeconomic markets-product, resource, and financial. Most modern currency is fiat money.ĬIRCULAR FLOW: A model of the continuous movement of production, income, and the services of scarce resources that flow between producers and consumers. This constitutes about 30 to 40 percent of the M1 money supply. economy is issued by the Federal Reserve System (paper) and the U.S. Metal coins are also frequently included under the generic heading of currency. PAPER CURRENCY: Paper usually issued by the national government that are used as money. It can be estimated using one of three methods: looking at total expenditure, at total income or using the production approach.AmosWEB means Economics with a Touch of Whimsy! The way of measuring all these flows of money is the gross domestic product (GDP). However, this diagram introduces a clear view of how the economy works. Things such as government spending (in the form of unemployment benefits, for example) or government income ( taxes) are not shown in the diagram. For instance, take government intervention. There are a few things that are not showed in this diagram that must be taken into account to really understand how the economy of a country works. It’s worth mentioning that, as usually, diagrams do not shown how the economy actually works. The exchanges made in the economy imply a redistribution of rent according to the diagram, and the creation of value makes the economy grow. When we combine both diagrams, we get the circular-flow diagram, as shown below. ![]() Factors of production flow form households (red arrow) to firms, so they can produce more goods and services. In this case, money flows from firms to households (green arrow in the diagram below) in the form of wages in exchange for labour, interests for capital and rent for the use of land. Firms use these factors in their production. The market for factors of production is the place where households offer their labour, capital and other factors such as land, receiving an income for their use. In this case, the flow of money (green arrow in the diagram below) goes from households to firms, in exchange for finished products, which flow from firms to households (red arrow). This market represents the place where money and goods are exchanged. In other words, is the place where firms sell the goods and services they have produced, receiving a revenue paid by households. The market for goods and services is the place where households spend their money buying goods and services produced by firms. market for factors of production (such as labour or capital), where firms purchase factors of production from households in exchange for money. market for goods and services, where households purchase goods and services from firms in exchange for money The circular-flow diagram (or circular-flow model) is a graphical representation of the flows of goods and money between two distinct parts of the economy: ![]()
