Unit 2 Notes


- Gross Domestic Product-  Total dollar value of all final goods and services produced within a countries  borders within a given year 


- Gross national product- total value of all final goods and services produced by americans in a year 

- GDP Equation = C + Ig+ G + X 

Gross Domestic Product 
C: Consumption  
- Ig: Gross Private Domestic Investment 
- G: Government spending 
- Xn: Exports-imports 

- Expenditure approach  
    • Add up the market value of all domestic expenditures made on final foods and services in a single year 
    • C+Ig+G+Xn 
- Income approach 
    • Adding up all the incomes earned by households and firms in a single year 
    • W+R+I+P+Statistical adjustments 
    • W: Wages 
    • R: Rents  
    • I: Interest 
    • P: Profit 
- Budget 
    • Government purchases of good + services + govt transfer payments - govt tax and fee collection 
      • If it is a positive number, it is a deficit  
      • If it is a negative number, it is a surplus 
- Trade 
    • Exports- Imports 
- GNP 
    • GDP+ net foreign factor payment 
- NNP: net national product 
    • GNP- depreciation 
- NDP 
    • GDP - depreciation 
- National income 
    •  GDP- Indirect business taxes - depreciation - net foreign factor payment  
    • Compensation of employees + proprietors income + rental income + interest income  + corporate profits  
- Disposable personal income  
    • national income - personal household taxes + gov. transfer payments 
- Nominal GDP 

    • Def: Value of output produced in current prices  
    • P x Q 
    • Can increase from year to year if either output or price increase 

- Real GDP 
    • Def: Value of output produced in constant or based year prices  
    • Adjusted for inflation  
    • P x Q  
    • Can increase from year to year only if output increases  
- Price index 
    • Def: measure inflation by tracking changes in the price of a market basket of goods compared to the base year 
    • price of market basket of goods in current year / price of market basket of goods in base year  
- GDP deflator 
    • A price index that is used to adjust nominal GDP to real GDP 
    • In the base year the GDP deflator is
      • = 100  for years after base year  
      • = >100 For years before the base year  
      • = <100 (Nomial GDP/ Real GDP)  ×100 
- Inflation 
  • (New GDP Deflator - Old GDP Deflator / Old GDP Deflator ) ×100 
- Inflation  
  • Rise in the general level of prices 
  • Standard inflation rate 2 to 3 percent  
- Measuring Inflation 
  • Inflation rate: measures the percentage increase in the price level over time  
  • Key indicator of an economy's strength  
  • A decline in the general price level
- Disinflation 
  • It occurs when the inflation rate itself declines  
- Consumer Price Index 
  • Measures inflation by tracking the yearly price of a fixed basket of consumer goods and services  
  • Indicates changes in the price level and cost of living  
- Solving inflation problems 
  • Finding inflation rate by using market basket data 
  • (current year market basket value - base year market basket value / base year market basket value ) x 100  
- Finding inflation rate using price index 
  • (current year price index - base year price index / base year  price index )x 100 
- Estimating inflation using the rule of 70 
  • Used to calculate the number of years it will take for the price level to double at any give rate of inflation 
  • Years needed to double inflation = 70/ annual inflation rate  
- Real wages  
  • (nominal wages / price level ) ×100  
- Finding real interest rates 
  •  nominal interest rate - inflation premium  
- Cost of borrowing or lending money that is adjusted for expected inflation 
  • Nominal interest rate 
  • Unadjusted cost of borrowing or lending money  
- Demand pull inflation 
  • Caused by excess of demand / output that pulls prices upwards 
- Cost pushed inflation 
  • Caused by a rise in per unit production cost due to increasing resource cost  
  • Borrowers 
  • Fixed Contract 
- Inflation Hurts... 
  • Fixed income 
  • Savers 
  • Lenders / creditors
