How can the Fed keep the economy from falling into a recession if the budget deficit is reduced? Use the IS-LM model to determine the impact of both the fiscal policy reducing the deficit and the monetary policy, which prevents output from falling. Using words, answer the following questions (and make sure to explain why things are happening to earn full points): - What happens to the curves and equilibrium values in the affected market(s) (i.e., the money market and/or goods market)? Explain. - What shifts in the IS-LM model? Explain. - Are the equilibrium levels of interest rates and income in the IS-LM model different than before the increase in oil prices? If so, how are they different? Explain.
The reduction of the budget deficit requires increases in taxes and/or decreases in government expenditures, both of which decrease planned expenditures (shifts the PE curve to the left) at any given real interest rate. This shifts the IS curve to the left. If the Fed does nothing, in the IS-LM model we see that the equilibrium level of output/income and the interest rate would decrease. The Fed attempts to maintain the original level of output/income by increasing the money supply M. Assuming P is fixed, in the money market this results in a shift of the money supply curve (M/P) to the right, which results in a lower real interest rate r at any level of output/income. This is a rightward shift of the LM curve. The result is that, relative to the original equilibrium, the output is the same, but the interest rate r is much lower, and lower than it would have been had the Fed done nothing. Equilibrium in the goods market maintains the original level of output, because the much lower interest rate after the Fed's action increases investment by enough to offset the decreases in consumption/government spending from the budget deficit reduction.
Consider a competitive economy in which factor prices adjust to keep the factors of production fully employed and the interest rate adjusts to keep the supply and demand for goods and services in equilibrium. The economy can be described by the following set of equations: Y = AKαL(1 - α) Y=C+I+G C = C(Y - T) I = I(r) How does an increase in government spending, holding other factors constant, affect the level of: public saving? private saving? national saving? the equilibrium interest rate? the equilibrium quantity of investment?
a. Public saving equals T - G. An increase in government spending, G, reduces public saving. b. Private saving equals Y - T - C. An increase in government spending does not affect privatesaving. c. National saving equals Y - C - G. An increase in government spending reduces nationalsaving by an amount equal to the increase in government spending. d. The equilibrium interest rate increases to bring desired investment into equilibrium with thereduced quantity of national saving. e. The equilibrium quantity of investment is reduced via the increase in the interest rate by anamount equal to the increase in government spending.
The reason that the income response to a fiscal expansion is generally less in the IS-LM model than it is in the Keynesian-cross model is that the Keynesian-cross model assumes that:
investment is not affected by the interest rate, whereas in the IS-LM model fiscal expansion raises the interest rate and crowds out investment.
