Objective:
What is the circular flow diagram of the economy?
What is GDP and how do you calculate it?Slide3
Circular-Flow Diagram
All countries calculate a set of numbers known as the national income and product accounts. The more reliable the accounts, the more economically advanced the country is.
Bureau
of Economic Analysis, a division of the Department of Commerce, calculates the national accounts (national income and product accounts) to keep track of spending of consumers, sales of producers, business investment spending, government purchases, and many other flows of money amount different sectors of the economy.Slide4
Circular-Flow Diagram
The circular-flow diagram is a simplified representation of the
macroeconomy
.
Shows the flows of money, goods and services, and factors of production through the economy
Underlying principle is that the flow of money into each market or sector is equal to the flow of money coming out of that market or sectorSlide5

Circular-Flow Diagram
The model represents the transactions that take place by two kinds of flows around a circle:
Flows of physical things such as goods; services, labor, or raw materials in one directions
Flows of money that pay for these things in the opposite directionSlide7
Circular-Flow Diagram
The simplest circular-flow diagram illustrates an economy that contains only two kinds of “inhabitants”: households and firms
Households –an individual or group of people who share their income
Firm – an organization that produces goods and services for sale and that employs members of the householdSlide8

Expanded Circular-Flow Diagram
Consumer spending – buying goods and services from domestic firms and from firms in the rest of the world
Households also derive additional income from their indirect ownership of the physical capital used by firms – stocks
Shares in the ownership of a company
Households also receive additional income from bonds – loans to firms in the form of an IOU that pays interest
The income the household receives from factor markets includes profit distributed to company shareholders and the interest payments on any bonds that they hold
Same goes for rent from firms
In a factor market, households receive income in the form of wages, profit, interest, and rent via factor marketsSlide11
Expanded Circular-Flow Diagram
Households spend most of the income received from factors of production on goods and services
Why do the markets for goods and services don’t absorb all of a household’s income?
Households don’t get to keep all the income they receive – have to pay income and sale taxes
Some households receive government transfers – payments that the government makes to individuals without expecting a good or service in return (unemployment insurance)
Total income households have left after paying taxes and receiving government transfers is disposable incomeSlide12
Expanded Circular-Flow Diagram
Why do the markets for goods and services don’t absorb all of a household’s income
?
Many households set aside a portion of their income for private savings
The private savings go into financial markets – individuals, banks, and other institutions buy and sell stocks and bonds as well as make loansSlide13
Expanded Circular-Flow Diagram
General Characteristic of the Circular-Flow Diagram:
The total sum of flows of money out of a given box is equal to the total sum of flows of money into that boxSlide14
Circular-Flow Model: Government
Government returns a portion of the money it collects from taxes to households in the form of government transfers
Government borrowing – the amount of funds borrowed by the government in the financial markets to buy goods and services
Government purchases of goods and services are the total expenditures on goods and services by federal, state, and local governments
Includes everything from military spending on ammunitions to your local public school’s spending on chalk, erasers and teacher salariesSlide15
The World
The world participates in the U.S. economy in 3 ways:
Exports
Imports
Foreigners can participate in U.S. financial markets through foreign lending and foreign borrowing
Foreign lending is lending by foreigners to borrowers in the U.S. and purchases by foreigners of shares of stock in American companies
Foreign borrowing is borrowing by foreigners from U.S. lenders and purchases by Americans of stock in foreign companiesSlide16
Circular Flow -- Firms
Firms also buy goods and services in the economy
Building a new factory
Accumulate an inventory
Inventories are goods and raw materials that firms hold to facilitate their operations
National accounts count this as investment spending
Spending on new productive physical capital, such as machinery and buildings, and on inventories – as part of total spending on goods and services
Accounted for due to they change the ability of a firm to make future salesSlide17
Gross Domestic Product (GDP)
Final goods vs. intermediate goods
Final goods and services are goods and services sold to the final, or end, user
Intermediate goods and services are goods and services that are inputs into the production of final goods and services
The purchaser is another firm, not the final userSlide18
Gross Domestic Product (GDP)
Gross Domestic Product is the total value of all
final goods and services
produced in an economy during a given period, usually a year.
GDP of 2011 was $15,094,025
Three ways to calculate GDP:
Survey firms and add up the total value of their production of final goods and services
Add up aggregate spending on domestically produced final goods and services in the economy
GDP = C + I + G + X - IM
Sum the total factor income earned by households from firms in the economy Slide19
Gross Domestic Product (GDP)
Aggregate spending is the sum of consumer spending, investment spending, government purchases of goods and services, and exports minus importsSlide20
