  4. The Government and Fiscal Policy fiscal policy The government’s spending and taxing policies. monetary policy The behavior of the Federal Reserve concerning the nation’s money supply.

  5. Government in the Economy discretionary fiscal policy Changes in taxes or spending that are the result of deliberate changes in government policy. Government Purchases (G), Net Taxes (T), and Disposable Income (Yd) net taxes (T) Taxes paid by firms and households to the government minus transfer payments made to households by the government. disposable, or after-tax, income (Yd) Total income minus net taxes: Y - T. disposable income ≡ total income − net taxes Yd≡Y − T

  6. Government in the Economy Government Purchases (G), Net Taxes (T), and Disposable Income (Yd)  FIGURE 9.1 Adding Net Taxes (T) and Government Purchases (G) to the Circular Flow of Income

  7. Government in the Economy Government Purchases (G), Net Taxes (T), and Disposable Income (Yd) When government enters the picture, the aggregate income identity gets cut into three pieces: And aggregate expenditure (AE) equals:

  8. Government in the Economy Government Purchases (G), Net Taxes (T), and Disposable Income (Yd) budget deficit The difference between what a government spends and what it collects in taxes in a given period: G - T. budget deficit ≡G − T

  9. Government in the Economy Government Purchases (G), Net Taxes (T), and Disposable Income (Yd) Adding Taxes to the Consumption Function To modify our aggregate consumption function to incorporate disposable income instead of before-tax income, instead of C = a + bY, we write C = a + bYd or C = a + b(Y − T) Our consumption function now has consumption depending on disposable income instead of before-tax income.

  10. Government in the Economy Government Purchases (G), Net Taxes (T), and Disposable Income (Yd) Planned Investment The government can affect investment behavior through its tax treatment of depreciation and other tax policies.

  11. Government in the Economy The Determination of Equilibrium Output (Income) Y = C + I + G

  12. Government in the Economy The Determination of Equilibrium Output (Income)  FIGURE 9.2 Finding Equilibrium Output/Income Graphically Because G and I are both fixed at 100, the aggregate expenditure function is the new consumption function displaced upward by I + G = 200. Equilibrium occurs at Y = C + I + G = 900.

  13. Government in the Economy The Determination of Equilibrium Output (Income) The Saving/Investment Approach to Equilibrium saving/investment approach to equilibrium: S + T = I + G To derive this, we know that in equilibrium, aggregate output (income)(Y)equals planned aggregate expenditure (AE). By definition, AE equals C + I + G; and by definition, Y equals C + S + T. Therefore, at equilibrium C + S + T = C + I + G Subtracting C from both sides leaves: S + T = I + G

  14. Fiscal Policy at Work: Multiplier Effects • At this point, we are assuming that the government controls G and T. In this section, we will review three multipliers: • Government spending multiplier • Tax multiplier • Balanced-budget multiplier

  15. Fiscal Policy at Work: Multiplier Effects The Government Spending Multiplier government spending multiplier The ratio of the change in the equilibrium level of output to a change in government spending.

  16. Fiscal Policy at Work: Multiplier Effects The Government Spending Multiplier

  17. Fiscal Policy at Work: Multiplier Effects The Government Spending Multiplier  FIGURE 9.3 The Government Spending Multiplier Increasing government spending by 50 shifts the AE function up by 50. As Y rises in response, additional consumption is generated. Overall, the equilibrium level of Y increases by 200, from 900 to 1,100.

  18. Fiscal Policy at Work: Multiplier Effects The Tax Multiplier tax multiplier The ratio of change in the equilibrium level of output to a change in taxes.

  19. Fiscal Policy at Work: Multiplier Effects The Balanced-Budget Multiplier balanced-budget multiplier The ratio of change in the equilibrium level of output to a change in government spending where the change in government spending is balanced by a change in taxes so as not to create any deficit. The balanced-budget multiplier is equal to 1: The change in Y resulting from the change in G and the equal change in T are exactly the same size as the initial change in G or T.

  22. The Federal Budget federal budget The budget of the federal government. The “budget” is really three different budgets. First, it is a political document that dispenses favors to certain groups or regions and places burdens on others. Second, it is a reflection of goals the government wants to achieve. Third, the budget may be an embodiment of some beliefs about how (if at all) the government should manage the macroeconomy.

  23. The Federal Budget The Budget in 2007

  24. The Federal Budget The Budget in 2007 federal surplus (+) or deficit () Federal government receipts minus expenditures.

  30. The Economy’s Influence on the Government Budget Tax Revenues Depend on the State of the Economy Tax revenue, on the other hand, depends on taxable income, and income depends on the state of the economy, which the government does not completely control. Some Government Expenditures Depend on the State of the Economy Transfer payments tend to go down automatically during an expansion. Inflation often picks up when the economy is expanding. This can lead the government to spend more than it had planned to spend. Any change in the interest rate changes government interest payments.

  32. The Economy’s Influence on the Government Budget Automatic Stabilizers automatic stabilizers Revenue and expenditure items in the federal budget that automatically change with the state of the economy in such a way as to stabilize GDP. Fiscal Drag fiscal drag The negative effect on the economy that occurs when average tax rates increase because taxpayers have moved into higher income brackets during an expansion.

  33. The Economy’s Influence on the Government Budget Full-Employment Budget full-employment budget What the federal budget would be if the economy were producing at the full-employment level of output. structural deficit The deficit that remains at full employment. cyclical deficit The deficit that occurs because of a downturn in the business cycle.

  36. increase in spending: - decrease in spending: = net increase in spending A P P E N D I X A DERIVING THE FISCAL POLICY MULTIPLIERS THE BALANCED-BUDGET MULTIPLIER • The balanced-budget multiplier is found by combining the effects of government spending and taxes: In a balanced-budget increase, ΔG = ΔT; so we can substitute: net initial increase in spending: ΔG − ΔG (MPC) = ΔG (1 − MPC)

  37. We can now apply the expenditure multiplier to this net initial increase in spending: A P P E N D I X A DERIVING THE FISCAL POLICY MULTIPLIERS THE BALANCED-BUDGET MULTIPLIER Because MPS = (1 − MPC), the net initial increase in spending is: ΔG (MPS)
