1. Fiscal policy Changes in federal taxes and purchases that are intended to achieve macroeconomic policy objectives Fiscal Policy: Congress & President (Treasury/OMB) Monetary Policy—ain’t fiscal policy—The Fed does M-policy Fiscal automatic stabilizers Government spending and taxes that automatically increase or decrease with the business cycle progressive income tax/unemployment benefits/food stamps / other entitlements. Tax wedge The difference between the pre-tax and post-tax return to an economic activity.  Disincentive to work???  Supply-side tax cuts Cyclically adjusted budget deficit or surplus The deficit or surplus in the federal government’s budget if the economy were at potential GDP.

2. Government Purchase and Tax Multipliers The Multiplier Effect and Aggregate Demand

3. Government Purchase Multiplier The Multiplier Effect of an Increase in Government Purchases This spending multiplier is analogous but not the same as the deposit multiplier

4. The Government Tax Multiplier Cut in tax rates affects equilibrium real GDP in two ways: (1)disposable income rises  consumption spending rises (2)the rate at which purchasing power leaks from the spending stream declines  the spending multiplier increases The less the marginal propensity to leak, the greater the spending multiplier. Recall: Spending Multiplier = 1/[Marginal Propensity to Leak] = 1/[Propensity Not to Respend Additional Income Domestically] =1/[Propensity to pay taxes, save and buy things from abroad]

5. Taking into Account the Effects of Aggregate Supply: Slowing the Multiplier The Government Purchases and Tax Multipliers Because the Price Level rises, Real GDP does not increase as much as it otherwise would  The multiplier effect is reduced

6. An Expansionary Fiscal Policy Increases Interest Rates Crowding out A decline in private expenditures as a result of an increase in government purchases…slowing the multiplier Money market

7. The Limits of Using Fiscal Policy to Stabilize the Economy Crowding Out in the Short Run

8. The 1960s: A Policy Menu? The Phillips Curve

9. Explaining the Phillips Curve with Aggregate Demand and Aggregate Supply Curves Phillips curve A curve showing the short- run relationship between the unemployment rate and the inflation rate. As long as SRAS is stable, get Phillips Curve relation

10. Explaining the Phillips Curve with Aggregate Demand and Aggregate Supply Curves Phillips curve A curve showing the short- run relationship between the unemployment rate and the inflation rate. As long as SRAS is stable, get Phillips Curve relation If people expect high inflation… Phillips curve shifts…

11. The Short-Run and Long-Run Phillips Curves The Inflation Rate and the Natural Rate of Unemployment in the Long Run Nonaccelerating inflation rate of unemployment (NAIRU) The unemployment rate at which the inflation rate has no tendency to increase or decrease.  Equilibrium unemploy  “Natural” unemploymt

13. The Effect of a Government Budget Deficit on Current Account Balance The Twin Deficits, 1978–2006 Current Account Deficit = Net Capital Inflows = National Borrowing = (I – S private ) + (G – T) = - NFI = Private Borrowing + Public Borrowing
