Unit 2 - GDP

GDP

  • Gross Domestic Product (GDP) - the total market value of all final goods and services produced within a country's borders within a given year
  • Gross National Product (GNP) - a measure of what its citizens produce and whether they produce these items within its borders
  • What's NOT Included in GDP
    1. Used or "Second-Hand" Products
      • avoid double or multiple counting
    2. Gifts/Transfer Payments (public or private)
      • no output being produced
      • public ex: welfare, social security
      • private ex: scholarship
      • recipients  contribute nothing to current production
    3. Stocks & Bonds
      • purely financial transaction
      • no output being produced
    4. Unreported Business Activities
      • "tips"
    5. Illegal Activities
      • drugs, prostitution, etc...
    6. Intermediate Goods
      • goods that require further processing before they are ready for final use
      • ex: big mac, car
    7. Non-Market Activities
      • volunteer/family work

Calculating GDP

  • both approaches should yield the same amount
    • expenditure = income

Expenditure Approach

  • adds up all the spendings on goods and services produced in a given year
GDP = C + Ig + G + X 
  • C - the personal consumption expenditures (67 % of the economy)
    • the purchase of finished goods and services
  • Ig - gross private domestic investment
    1. covers new factory equipment
    2. factory equipment maintenance
    3. construction of housing
    4. unsold inventory of products built in a year
  • G - government spending
  • Xn - net exports
    • (exports - imports)

Income Approach

  • adds up all the income that resulted from selling all final goods and services produced in a given year
GDP = WRIP + Statistical Adjustments
  • W - wages (salary, salary supplements, compensation of employees)
  • R - rents (rental income)
  • I - interests (interests income)
  • P - profits (proprietors income)

Formulas

  1. Trade
    • (export - import)
    • [-] = deficit
    • [+] = surplus
  2. Budget
    • (govt purchases of goods & services) + (govt transfer payments) - (govt tax & fee collections)
    • [-] = surplus
    • [+] = deficit
  3. National Income
    • Option 1: (compensation of employees) + (rental income) + (interests income) + (proprietors income) + (corporate profits)
    • Option 2: (GDP) - (indirect business taxes) - (depreciation *consumption of fixed capital*) - (net foreign factor payments)
  4. Disposable Personal Income
    • (national income) - (personal household taxes) + (govt transfer payments)
  5. Net National Product
    • (GNP) - (depreciation)
  6. Net Domestic Product
    • (GDP) - (depreciation)
  7. GNP
    • (GDP) + (net foreign factor payment)
  8. Gross Private Domestic Investment
    • (net private domestic investment) + (depreciation)

Nominal vs. Real GDP

  • Nominal GDP - the value of output produced in current prices
    • formula: P x Q
    • can increase from year to year if either output or price increases
  • Real GDP - the value of output produced in constant base-year prices that is adjusted for inflation
    • formula: P x Q
    • can increase from year to year if any output increases
  • in the base-year, the current price is equal to constant prices
    • base year → Nominal GDP = Real GDP
  • in years after the base-year, nominal GDP will exceed real GDP
  • in years before the base-year, real GDP will exceed nominal GDP

  • GDP Deflator - a price index used to adjust from nominal to real GDP
    • (nominal GDP / real GDP) x 100
  • in the base-year, the GDP deflator will equal 100
  • for years after the base-year, GDP deflator will be greater than 100
  • for years before the base-year, the GDP deflator will be less than 100

  • Inflation - a general rise in the price level
    • Inflation Rate = (new price index - old price index) / (old price index) x 100
  • Consumer Price Index (CPI) - measures the cost of a market basket of goods of a typical urban American family
    • (cost of a market basket of goods in a given year) / (cost of a market basket of goods in the base-year) x 100

Unit 7 - Comparative & Absolute Advantage

Absolute Advantage looks at who can produce more with the same resources or who can produce the same output with less resources ex: Pap...
