Questions and Answers

What is one of the three sources to finance a deficit according to the classical equilibrium model?

  • Increasing tariffs
  • Cutting public services
  • Government borrowing (correct)
  • Reducing consumer confidence

    • If government cuts taxes and consumers believe that spending will decrease in the near future, consumption will fall less.

    True

    What does the classical equilibrium model assume about the relationship between savings (S) and investment (I) when government debt increases?

    S = I

    <p>Perfect Ricardian equivalence = Consumers adjust their savings in anticipation of future taxes. Government spending cut = Can lead to an increase in real income in the private sector.

    Study Notes

    Quantity Theory of Money

    • The price level is related to output and money quantity.
    • The equation of exchange models money supply and transactions.
    • Focuses on money supply, all transactions, and other factors.
    • M: quantity of money.
    • V: velocity of money.
    • P: price index for final goods.
    • Y: real output.
    • MV = PY
    • Income velocity of money (purchase of currently produced final goods).
    • PY = Nominal GDP.
    • If MV = PQ, then the price vector of all goods is considered.
    • Cambridge approach emphasizes money demand.
    • Md = k(PY), where Md is money demand, and k is the proportion of nominal income demanded as cash holding.

    Classical Theory of Interest Rate

    • Equilibrium interest rate is where lending and borrowing desires equal.
    • Interest rate is the cost of borrowing.
    • Investment is linked to expected profits and interest rates.
    • Credit market, demand (firms & government), and supply (savers), relate inversely with interest rates.
    • Investment is inversely related to interest rates.
    • Savings and Investment = (G-T) + I.
    • Two reasons for full employment in classical macroeconomics are supply is vertical and the interest rate relates.

    Policy Implications of Classical Equilibrium Model

    • Fiscal policy (changes in G) assumes a balanced budget.
    • Funding deficits can stem from: taxes, debt, or money creation.
    • Ricardian equivalence assumes consumers understand future tax implications, causing reduced today's consumption.
    • Debt increases impact consumption and investment, but not the level of GDP.
    • Crowding out effect is when private sector resources are reduced due to deficit spending.
    • Fiscal policy effects do not affect price levels.
    • Monetary policy (changes in M) affects price levels.
    • Money neutrality: equilibrium real values aren't dependent on money quantity.

    Model Example

    • Macroeconomic models are available in Blackboard's spreadsheet.
    • Model functions include: Y = A(K^α)(N^1-α).
    • Labor demand depends on profit maximization.
    • Real wage = marginal product of labor.
    • Labor market equilibrium conditions are NS = ND.
    • Parameter values are provided.
