Unit 2 Notes

Circular Flow Chart 

Circular Flow Chart 




















GDP: Gross Domestic Product; total dollar value of all final goods & services produced within a country's borders within a given year. (ONLY compass what is produced in AMERICA; can DECREASE when not spending money) 

GNP: Gross National Product; it measures of what its citizens produced and whether they produce these items within its borders. 

National Income Accounting: Economist collets statistic on production, income, investment, and savings. 

Number 1 sign of checking GDP- Gas money; transportation. 

Formula to GDP- C+Ig+G+Xn

What's included in GDP?
  • C- Consumption; takes 67% of economy's final goods and services; even part of wages.
  • Ig- Gross Private Domestic Investment; factory equipment maintenance, new factory equipment, construction of housing, unsold inventory of products built in a year. 
  • G- Government Spending; government buying military weapons, buying school/ bus.
  • Xn- Net Exports; Exports-Imports
What's  NOT included in GDP?
  • Used/second hand goods (Hand me downs)
  • Intermediate Goods: Goods & services that are purchased for resale or for further processing/ manufacturing (NOT COUNTED; BUYING WHOLE CAKE NOT LAYERS)
  • Non-Market Activities: Volunteer work. (Ex. baby sit, illegal drug sales, underground activities) 
  • Financial Transactions: Stocks, bonds, real-estate 
  • Gifts/Transfer Payments:
Public- recipients contribute nothing to cut tent production. (Ex. Social security, welfare payments)
Private- Produces no output; simply transferring funds from 1 individual to another. (Ex. scholarship, Christmas gift) 

GDP & GNP Formulas (1/28/15)

Budget: Gov. purchases of goods & services + Gov. transfer payments - Gov. tax & fee collections 

Positive- budget deficit
Negative- budget surplus

Trade: Exports - Imports 
GNP: GDP + Net Foreign Factor Income (use expenditure approach for GDP)
Net National Product (NNP): GNP - Depreciation 
NDP: GDP - Depreciation 
National Income: GDP - Indirect Business Taxes - Depreciation - Net Foreign Factor Payment
OR
                            Compensation of Employees + Rental Income + Interest Income + Proprioriters               Income + Corperate Profits

Disposal Personal Income: National Income - Personal Household Taxes + Gov. Transfer Payments

Expenditures Approach: Adding up market value of all domestic expenditures made on all final goods & services in a single year.
C + Ig + G + Xn (Exports-Imports) = GDP

Income Approach (WHAT YOU REPORT): Adding up all income earned by households and firms in a single year.
GDP= W + R + I + P + Statistical Adjustments

  • Wages: Compensation of employees; salary.
  • Rents: From tenants to land lords; lease payments that corporations pay for use of space.
  • Interest: Money payed by private businesses to suppliers of loans, used to purchase capital.
  • Profit:
  1. Corporate income taxes.
  2. Dividends 
  3. Undistributed corporate profits. (Ex. dividens, depreciation, wages & salaries, corporate income tac, undistributed rotate profits, net foreign factor income earned)

Nominal GDP v. Real GDP (1/29/15)

Nominal GDP: Value of output produced in current prices; can increase from year to year of either output are price increase.

Real GDP: Value of output produced in base year or constant prices; adjusted for inflation; can increase from year to year only if output increases. (Base year/ earlier year) 

Nominal GDP & Real GDP Formula- P X Q

Calculating Nominal & Real GDP Ex:

                   Yr.1 Q          Yr.4 P          Yr.1 P          Yr.4 Q       
Comp.            10                17              $2000         $2200
T.V                 15                20              $500           $550    

Nominal GDP Steps-
  1. 17 x $2200 = $37400
  2. 20 x $550 = $1100
  3. $37400 + $1100 = $48400
Real GDP Steps-
  1. 17 x $2000 = $34000
  2. 20 x $500 = $10000
  3. $34000 + $10000 = $44000
Price Index: A measure of inflation by tracking changes in market basket of goods compared with the base year. 
  • Formula for Price Index- Price Market Basket of goods in current year/ Price Market Basket of goods in base year x 100
GDP Deflector: Price index used to adjust from Nominal GDP to Real GDP
-In base year, GDP deflector is equal to 100
-For years after base year, GDP deflector is greater than 100
-Years before base year, GDP deflector is less than 100
  • Formula for GDP Deflector- Nominal GDP/ Real GDP x 100
Inflation Formula- New GDP Deflector - Old GDP Deflector/ Old GDP Deflector x 100


Inflation (2/2/15)

Inflation: A rise in general level of prices. 
  • Standard inflation 2-3%
Inflation Rate: It measure the percentage increase in price level over time; offers key indicator pf economy's health. 

Deflation: Decline in general price level.

Disinflation: Occurs when inflation rate declines.

Consumption Price Index (CPI): Measures inflation by tracking yearly price of fixed basket of consumer goods & services;indices changes in price level and cost of living.


  • Solving inflation problems: 

A) Finding inflation rate using basket market.
-Curent year market basket - Base year market basket value / Base year market basket value x 100

B) Finding inflation rate using price indexes 
-Curent year price index - Base year index / Base year price index x 100

C) Estimating Inflation
-Rule of 10 used to calculate number of years it would take for price level to double at any given rate of inflation.

  • Ex. Years needed to double inflation = 70 (Annual rate is 5%); Years needed to double 14
D) Determining real wages. 
-Real wages = Nominal Wages / Price Level x 100

E) Finding Real Interest Rate
-Real interest rate - Nominal interest rate - inflation premium will give you real interest rate.

Real Interest Rate: The cost of borrowing or lending money that is adjusted for inflation; always expressed as percentage.

Nominal Interest Rate: Unadjusted cost of borrowing or lending money,

Rule of 70:    Used to calculate the number of years it will take for the price level to double at any given rate of inflation.

Causes of Inflation

A) Demand Pull Inflation: Caused by an excess of Demand over Output that pulls prices upward. (Ex. Concert; more people, more higher prices, closer seats.)

B) Cost Pull Inflation: Caused by a rise in per uint production cost due to increasing resource cost. (Ex. If gas oil goes up, plane tickets go up.)

Effects of Inflation:
  • Anticipated- Expecting to happen.
  • Unanticipated- Suddenly happening. (Ex. Manager says everybody is fired; sudden)

Hurt by Inflation

  • Fixed Income (Ex. Social Security, scholarship, grants)
  • Savers (Can not change)
  • Lenders/ Creditors (Worth less)

Help by Inflation

  • Borrowers- debt will be repaid with cheaper dollars than those loaned out. 

Unemployment (2/3/15)

Unemployed: Percentage of people who do not have jobs but in labor force.

Labor Force: Number people in country that are classified either employed or unemployed

  • Unemployment Rate Calculation: Number unemployed/ Number unemployed + Number employed x 100
Unemployment Percentage: 4-5%

Not in Labor Force

  1. Kids
  2. Military personnel 
  3. Mentally insane 
  4. Prison
  5. Retired 
  6. Stay at home parents 
  7. Full time students
  8. Discourage workers 

Types of Unemployment

  • Frictional: "Between jobs" People between jobs because they choose new opportunities, choices, life styles, new education levels. 
  • Structural: Technology changing, lack of skills, declining industry (NASA, type writer technician)
  • Seasonal: Waiting right season to go to work. (Ex. Santa Claus, easter bunny, life guards)
  • Cyclical: Occurs due to swing in economy deals with business cycle. (Ex. Trough)
Full Employment: Occurs when no cyclical
-Unemployment is still present but only 4-5%; Economy producing at full potential possible. (Not everybody working)

National Rate of Unemployment (NRU): 4-5%

Why unemployment is bad?

  1. Not enough consumption (GDP) Not working, not buying 
  2. Too much poverty 
  3. Too much government assistance

Why unemployment is good?

  1. Less pressure to raise wages
  2. More workers available for future expansion. 
Okun's Law: For every 1% of unemployment above the NRU causes 2% decline in real GDP (Ex. If unemployment 3.5%, NRU is 7% (3.5 x 2 = 7) )








1 comment:

  1. You have a very well written post, but there are also trade deficits and surpluses which can be recognized with the answer of the trade formula (exports-imports). There is a trade deficit if the answer is a negative number, and a trade surplus when the number is positive.
