In this case, the United States has borrowed from Argentina. It has received goods from Argentina but has promised that it will give some goods or services to Argentina in the future. The United States has a comparative advantage in corn production because its opportunity cost (0.5 oil) is less than Saudi Arabia’s . On the other hand, Saudi Arabia has a comparative advantage in oil production because its opportunity cost (0.25 corn) is less than the US opportunity cost . First, you need to calculate the opportunity cost of producing each good for each country. Even if Jethro is willing to work like a mule while everyone else sits around, he, like all mortals, only has 24 hours in a day.
Televisions, refrigerators, or tables are durable goods because they will last three or more years when used on a regular basis. Both micro and macroeconomics which markets are represented in the simple circular-flow diagram? are explained with theories and models. The most well-known theories are probably those of supply and demand, but you will learn many others.
1 The Circular-Flow Model
The movie company—and, more generally, the US economy—has now acquired a foreign asset—Australian dollars. The spending by households on goods and services is funded by the income that households earn. But this income comes from firms, and they get their income from the spending of households. Thus there is a circular flow of income in an economy as a whole. The money flows among the different sectors of an economy as individuals and firms buy and sell goods and services. Allocative efficiency means that the particular combination of goods and services on the production possibility curve that a society produces represents the combination that society most desires.
So, in the markets for goods and services, businesses sell goods and services and households buy goods and services. Products flow one way (counter-clockwise) and money flows the other . Hence, spending on goods and services flows from households to firms, and income in the form of wages, rent, and profit flows from firms to households. Circular flow Diagram is a visual model of the economy that shows how dollars flows through markets among households and firms. Draw a box outside the original circular flow to represent the foreign country. Draw an arrow from the foreign country to firms, to represents imports. Draw an arrow in the reverse direction representing payments for imports.

The models can be made more complex to include additions to the money supply, like exports, and leakages from the money supply, like imports. In short, the market for goods and services is simply where the goods and services produced by businesses are bought. Households use part of their incomes to buy goods and services. For example, at the diner, revenue comes from customers paying for their food. At that point, the story of the economy’s circular flow starts once again.
If the pizza place uses a wood-burning oven, we would include the wood as a raw material. If the establishment heats the oven with natural gas, we would count this as a raw material.
The Simplest Version of the Circular Flow
There is a flow of goods from firms to households and a flow of labor services from households to firms. Economic growth will occur if the country’s output of goods and services increases over time. The circular flow diagram will continue to expand, and more and more items will be for sale as long as people have jobs and continue to spend their money on those products. If people lose their jobs or are fearful about the future, they will not spend money, which would hurt the circular flow of economic activity, and the overall economy will contract. The 5-sector circular flow model consists of five sectors.
- Why are so few AIDS patients in Africa and Southeast Asia treated with the same drugs that are effective in the United States and Europe?
- Here are the most common combinations of economic factors in the circular flow.
- This cycle shows how the resources of one sector are used to develop others in a cyclical manner.
- The circular flow model, also known as the circular flow of income, describes how money and economic resources flow in cycles between different sectors in an economic system.
- We can use the terms income, spending, production, and GDP completely interchangeably.
- Flows from households and firms to government are in the form of taxes.
Learn how prices are set, the motivations of buyers and sellers interact, and the ways in which markets are structured here. Households bring money to these markets, and businesses provide the goods and services.
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. The behavior of firms and individuals inside of markets is the focus of microeconomics.
In the three-sector circular flow model, the government is added to the basic circular flow model (two-sector model). When G + X + I is greater than T + M + S, the level of national income will increase.
Concept 20: Equilibrium Prices
Savings and investments are assumed in the five-sector model, which flow from other sectors with residual cash into the financial institutions, then out to the sectors that need money. As long as lending is equal to borrowing , the circular flow reaches an equilibrium and can continue forever. In a three-sector model, government sector cash flows are included. The government injects money into the circle through government spending on programs such as Social Security and the National Park Service. It also extracts money from households and businesses by way of taxes.
