Chapter 11 - Fiscal Policy
MACROECONOMICS EXAM REVIEW CHAPTERS 11 THROUGH 16 AND 18 Key Terms and Concepts to Know CHAPTER 11 - FISCAL POLICY I. Theory of Fiscal Policy Fiscal Policy is the use of government purchases, transfer payments, taxes, and borrowing to affect macroeconomic variables such as real GDP, employment, the price level, and economic growth. A. Fiscal Policy Tools • Automatic stabilizers: Federal budget revenue and spending programs that automatically adjust with the ups and downs of the economy to stabilize disposable income. • Discretionary fiscal policy: Deliberate manipulation of government purchases, transfer payments, and taxes to promote macroeconomic goals like full employment, price stability, and economic growth. • Changes in Government Purchases: At any given price level, an increase in government purchases or transfer payments increases real GDP demanded. For a given price level, assuming only consumption varies with income: o Change in real GDP = change in government spending × 1 / (1 −MPC) other things constant. o Simple Spending Multiplier = 1 / (1 − MPC) • Changes in Net Taxes: A decrease (increase) in net taxes increases (decreases) disposable income at each level of real GDP, so consumption increases (decreases). The change in real GDP demanded is equal to the resulting shift of the aggregate expenditure line times the simple spending multiplier. o Change in real GDP = (−MPC × change in NT) × 1 / (1−MPC) or simplified, o Change in real GDP = change in NT × −MPC/(1−MPC) o Simple tax multiplier = −MPC / (1−MPC) B. Discretionary Fiscal Policy to Close a Recessionary Gap Expansionary fiscal policy, such as an increase in government purchases, a decrease in net taxes, or a combination of the two: • Could sufficiently increase aggregate demand to return the economy to its potential output.
