Economics: Unit 2: Chapter 7: GDP, Real GDP, and Nominal GDP

GDP (Gross Domestic Product): The total value of all final goods and services produced within a country's border within a given year.



GNP (Gross National Product): The total value of all final goods and services produced by Americans in a given year.

What is included in GDP?
  • Final goods and services
  • Income earned
  • Interest payments on corporate bonds
  • Current production of final goods and services
  • Unsold outputs (business inventories)
What is not included in GDP?
  • Intermediate goods
  • Transfer payments (public or private)
    • Scholarships, social security
  • Purchases of stocks and bonds
  • Used or second handed sales (avoid double count)
  • Non-market transactions
    • Babysitting
    • Illegal drugs
    • Prostitution
    • Doing your own house work or repairs
    • Growing your own products for personal consumption

How do you calculate GDP?
                                 

Expenditure Approach
Income Approach
GDP=C+Ig+G+Xn
GDP=W+R+I+P+Statistical Adjustments
Used when calculating goods and services
Used for calculating factors of production

                        
C=Personal Consumption (anything you buy)           
W=Wages (Compensation of employees , salary)
Ig= Gross Private Domestic Investment 
·        Factory Equipment
·        New construction of homes and businesses
·        Tools and machines

R= Rents (rental income)           
G=Government Spending
I=Interest (interest income)
Xn= Net exports (exports-imports)
P=Payments (proprietors income)

Budget Deficit: The total amount of government borrows within a year. 
  • Total government spending exceeds tax and fee revenue
  • Equation: (Transfer Payments + Government Purchases - Government Tax and Fee Collection)
  • If the answer is negative, it is a budget surplus
  • If the answer is positive, it is a budget deficit


Trade = (exports - imports)
  • If the answer is positive, it is a surplus
  • If the answer is negative, it is a deficit
National Income Equations:
  • (GDP - indirect business tax - depreciation - net foreign factor)
  • (Compensation of employees + proprietors income + rental income + interest income + corporate profit)
Disposable Personal Income = (National Income - Household Taxes + Government Transfer Payments)

Net Domestic Product = (GDP - Depreciation) (Depreciation can also be called consumption of fixed capital)

Net National Product = (GNP - Depreciation) (Depreciation can also be called consumption of fixed capital)

GNP = (GDP + Net Foreign factor Payment)

Normal GDP: The value of output produced at current prices
  • Nominal GDP = Price * Quantity
Real GDP: The real value of output produced at constant or based year prices.
  • Real GDP = Price * Quantity
  • Nominal GDP can increase year to year. If either output or prices increase, Real GDP can only increase if output increases.
Gross Private Domestic Investment = (Net private domestic investment + Depreciation) 

To measure economic growth, find RGDP.
To measure inflation, find NGDP.


Ex. In year 1, 10 computers are sold at $2000 each, and 15 televisions were sold at $500 each. In year 2, 17 computers were sold at $ 2200 each, and 20 televisions were sold at $550 each. 

Nominal GDP is (17*2200) + (20*550) = $48400

Real GDP is (17*2000)+(20*500) = $44000


GDP Deflator = ((Nominal GDP/Real GDP) *100)
  • In base year, GDP is always equal to 100
  • For year after the base year, GDP deflator is greater than 100
  • For years before the base year, GDP deflator is less than 100

  1. Your notes were very helpful and well separate do. Your details on all of the equations helped me understand more of what each equation specifies in. The trade and budgets were well explained when regarding to surplus and deficit!
