GDP & GNP (Unit 5)

Gross National Product and

Gross Domestic Product

Standard 12.5: Students analyze the aggregate economic behavior of the U.S. Economy

SWBAT: Explain the difference between GDP and GNP, measure and understand what the numbers

indicate.

What’s the Difference???

• GNP(Gross National Product)

-Total $ value of all final goods and services

produced annually by American residents,

whether these resources are located in the U.S. or

abroad

• GDP(Gross Domestic Product)

-Total $ value of all final goods and services produced annually within the boundaries of the U.S., whether by

Americans or Foreigners

GNP or GDP?Determine whether each of the following falls under GNP or GDP. Explain your rationale!!!1. Mexico builds a shoe company in Texas.2. Miss Stack moves to Brazil and becomes

an Economics teacher abroad.3. Due to high labor costs in the U.S., Nike

moves its entire company to China.4. Microsoft decides to build a computer

factory on the corner of Inglewood and El Segundo.

5. Come up with an example of GDP yourself and write it in as #5

6. Come up with an example of GNP yourself and write it in as #6

Measuring GDP/GNP

• Two Ways To Measure GDP/GNP:

1.) Expenditure Approach

2.) Flow of Income Approach (Circular

Flow Model)

1. Expenditure (Expense) Approach

GDP/GNP=C+I+G+Xn

C+I+G+Xn• Consumption (C): Household spending. Makes up two-

thirds of GDP spending. [the biggest spending sector of the economy]

• Investment (I): Spending by Businesses on machinery, factories, equipment, tools, and construction of new buildings.

• Government (G): Spending by all levels of government on goods and services.

• Net Exports (X-M) = Exports minus imports: Spending by people abroad on U.S. goods and services (exports, or X) minus spending by people in the U.S. on foreign goods and services (imports, or M)

Practice Problem!!! Using the Expenditure Formula, solve for GDP/GNP!!!Calculate GDP/GNP when:C=500 millionI=150 millionG=300 millionX=200 millionM=300 million

The Expenditure Approach

• Step 1: For each of the scenario, determine which category of spending it falls under.

• Step 2: Then, write whether or not GDP/GNP increased or decreased using arrows.

• Step 3: Create a tree map -- pull out a blank piece of paper and fold into 4 equal columns and label your top branch ‘The Expenditure Approach’ and the others appropriately.

• Step 4: Cut and glue into the correct column!!!

• Step 5: If time, draw a symbol next to each.

2. Circular Flow of Income ApproachGDP/GNP=W+I+R+P

1. Households provide businesses with resources (land, labor, capital, entrepreneurship)

2. In return for these resources, businesses pay $$$ in the form of Wages, Interest, Rent and Profit.

You add up all the money income derived from the production of this year’s outputs.

Wrap-Up

• What is the difference between GDP/GNP?• What are the two methods for measuring

each?• What is the main purpose of determining a

countries GDP? GNP?
