Study Notes

Gross Domestic Product (GDP)

  • GDP is the total market value of all final goods and services produced within a country in a given year.
  • It includes all goods produced domestically, regardless of ownership (foreign-owned businesses are included).
  • It excludes goods produced overseas.

Circular Flow Diagram

  • Shows the flow of money and goods/services between households and firms.
  • Households provide labor (L) and capital (K) to firms in exchange for income (Y).
  • Firms use these factors to produce goods (using inputs like raw materials) which are then sold to households for consumption (C).
  • Government (G) provides public goods/services and collects taxes (T).
  • Foreign markets facilitate the flow of exports (EX) and imports (IM)
  • Financial markets facilitate the flow of capital and funds.

Government

  • Government budget surplus (SG) = T – G
  • Budget surplus: SG > 0
  • Budget deficit: SG < 0

Foreign Markets

  • Net exports (NX) = EX - IM
  • NX is part of the current account (CA).
  • Foreign businesses need to buy Canadian currency to buy Canadian goods

Firms

  • Production function: Y = F(K, L) - Output (Y) depends on capital (K) and labor (L)
  • Expenditures = C + I + G + NX

Households

  • Income (Y) = labor income (WL) + capital income (rK) + depreciation(δK)
  • Household saving (SH).

Value Added Approach

  • GDP equals the sum of all value added at each stage of production.
  • Value added is the difference between a firm's sales revenue and the cost of the intermediate goods it purchases.
  • Calculate GDP by summing the value added across all firms.

Expenditure Approach

  • Y = C + I + G + NX (consumption + Investment + Government purchases + Net Exports)

Income Approach

  • Y = WL + RK (labor income + capital income)

Real GDP per capita

  • Average income of residents in terms of the domestic currency.
  • Nominal GDP divided by the population.
  • Useful for comparing incomes within a country over time.
  • Adjusting for inflation is important when comparing incomes across countries or time periods.

Limitations of GDP

  • GDP does not account for:
    • Non-market activities
    • Shadow economy
    • Environmental degradation
    • Leisure time
    • Income distribution

Other Measures of Standard of Living

  • GDP is not the only indicator of standard of living.
  • Other measures include life satisfaction, average years of schooling, infant mortality, and life expectancy.
  • These measures provide a more comprehensive picture of well-being.
