Fiscal Policy Chapter 12 McGraw-Hill/Irwin Copyright © 2011 by The McGraw-Hill Companies, Inc. All Rights Reserved. Fiscal Policy • Fiscal policy is the use of government taxes and spending to alter macroeconomic outcomes. • The premise of fiscal policy is that the aggregate demand for goods and services will not always be compatible with economic stability. LO-1 12-2 John Maynard Keynes and Fiscal Policy • John Maynard Keynes explained how a deficiency in demand could arise in a market economy. • He showed how and why the government should intervene to achieve macroeconomic goals. • He also advocated aggressive use of fiscal policy to alter market outcomes. LO-1 12-3 Components of Aggregate Demand • Aggregate demand is the total quantity of output demanded at alternative price levels in a given time period, ceteris paribus. LO-1 12-4 Components of Aggregate Demand • The four major components of aggregate demand are: – Consumption (C) – Investment (I) – Government spending (G) – Net exports (exports minus imports) (XIM) AD = C + I + G + (X - IM) LO-1 12-5 Figure 12.1 12-6 Consumption (C) • Consumption refers to expenditures by consumers on final goods and services. • Consumption spending accounts for approximately two-thirds of total spending in the U.S. economy. • Consumers often change their spending behavior. LO-1 12-7 Investment (I) • Investment refers to expenditures on (production of) new plant and equipment in a given time period, plus changes in business inventories. LO-1 12-8 Government Spending (G) • Government spending includes expenditures on all goods and services provided by the public sector. • Income transfers are not included: – Income transfers are payments to individuals for which no services are exchanged. LO-1 12-9 Net Exports (X-IM) • Net exports is the difference between export spending and import spending. • Currently, Americans buy more goods from abroad than foreigners buy from us. • This means that U.S. net exports are negative. LO-1 12-10 Aggregate Demand in 2008-09 • A slowdown in consumer spending reversed the growth path of AD. • Businesses decreased inventories and employment. • Government increased spending in an attempt to stimulate the economy. • The trade deficit decreased as buyers in the U.S. bought fewer imported items. LO-1 12-11 Equilibrium • Aggregate demand is not a single number but instead a schedule of planned purchases. • Macro equilibrium is the combination of price level and real output that is compatible with both aggregate demand and aggregate supply. LO-1 12-12 Equilibrium • There is no guarantee that AD will always produce an equilibrium at full employment and price stability. • Sometimes there will be too little demand and sometimes there will be too much. LO-2 12-13 Figure 12.2 12-14 The Nature of Fiscal Policy • C + I + G + (X - IM) seldom adds up to exactly the right amount of aggregate demand. • The use of government spending and taxes to adjust aggregate demand is the essence of fiscal policy. LO-2 12-15 Figure 12.3 12-16 Fiscal Stimulus • If AD falls short, there is a gap between what the economy can produce and what people want to buy. • The GDP gap is the difference between full-employment output and the amount of output demanded at current price levels. LO-4 12-17 More Government Spending • To help with the 2008-09 recession, President Obama created huge increases in government spending. • Increased government spending is a form of fiscal stimulus: – Fiscal stimulus–tax cuts or spending hikes intended to increase (shift) aggregate demand. LO-4 12-18 Multiplier Effects • An increase in spending results in increased incomes. • All income is either spent or saved: – Saving–Income minus consumption; that part of disposable income not spent. LO-3 12-19 Multiplier Effects • Part of each dollar spent is re-spent several times. • As a result, every dollar has a multiplied impact on aggregate income. LO-3 12-20 Multiplier Effects • The marginal propensity to consume (MPC) is the fraction of each additional (marginal) dollar of disposable income spent on consumption: change in consumption MPC = change in disposable income LO-3 12-21 Multiplier Effects • The marginal propensity to save (MPS) is the fraction of each additional (marginal) dollar of disposable income not spent on consumption: change in saving MPS = change in disposable income LO-3 12-22 Multiplier Effects • Spending and saving decisions are connected: MPS = 1 – MPC or MPC + MPS = 1 LO-3 12-23 Multiplier Effects and the Circular Flow • The fiscal stimulus to aggregate demand includes: – The initial increase in government spending. – All subsequent increases in consumer spending triggered by the government outlays. • Income gets spent and re-spent in the circular flow. LO-3 12-24 Figure 12.6 12-25 Spending Cycles • The demand stimulus initiated by increased government spending is a multiple of the initial expenditure. LO-3 12-26 Multiplier Formula • The multiplier is the multiple by which an initial change in aggregate spending will alter total expenditure after an infinite number of spending cycles: Multiplier = 1 / (1-MPC) LO-3 12-27 Multiplier Formula • The multiplier process at work: Total change in spending = Multiplier x Initial change in government spending • Every dollar of fiscal stimulus has a multiplied impact on aggregate demand. LO-3 12-28 Tax Cuts • Rather than increasing its own spending, government can cut taxes to increase consumption or investment spending. • A tax cut directly increases disposable income: – Disposable income is the after-tax income of consumers. LO-4 12-29 Taxes and Consumption • As long as the MPC is greater than zero, a tax cut will stimulate more consumer spending: Initial increase in consumption = MPC x tax cut LO-3 12-30 Taxes and Consumption • The cumulative increase in aggregate demand equals a multiple of the taxinduced change in consumption. Cumulative change in spending = multiplier x initial change in consumption LO-3 12-31 Taxes and Consumption • A tax cut that increases disposable incomes stimulates consumer spending. • The cumulative increase in aggregate demand is a multiple of the initial tax cut. LO-3 12-32 Inflation Worries • Whenever the aggregate supply curve is upward-sloping, an increase in aggregate demand increases prices as well as output. • President Clinton raised taxes partly because he feared inflationary pressures were building. LO-4 12-33 Fiscal Restraint • Fiscal restraint may be the proper policy when inflation threatens: – Fiscal restraint–tax hikes or spending cuts intended to reduce (shift) aggregate demand. LO-4 12-34 Figure 12.8 12-35 Budget Cuts • Cutbacks in government spending directly reduce aggregate demand. • As with spending increases, the impact of spending cuts is magnified by the multiplier. LO-3 12-36 Multiplier Cycles • Government cutbacks have a multiplied effect on aggregate demand: Cumulative reduction in spending = multiplier x initial budget cut LO-3 12-37 Tax Hikes • Tax increases reduce disposable income and thus reduce consumption. • This shifts the aggregate demand curve to the left. • Tax increases have been used to “cool down” the economy. LO-4 12-38 Tax Hikes • The Equity and Fiscal Responsibility Act of 1982 increased taxes to reduce inflationary pressures. • President Clinton restrained aggregate demand in 1993 with a tax increase, but increased aggregate demand in 1997 with a five-year package of tax cuts. LO-4 12-39 Fiscal Guidelines • The policy goal is to match aggregate demand with the full-employment potential of the economy. • The fiscal strategy for attaining that goal is to shift the aggregate demand curve. LO-4 12-40 Unbalanced Budgets • The use of the budget to manage aggregate demand implies that the budget will often be unbalanced. LO-5 12-41 Figure 12.9 12-42 Budget Deficit • Budget deficit–the amount by which government expenditures exceed government revenues in a given time period: Budget deficit = Government spending > Tax revenues LO-5 12-43 Budget Deficit • The government borrows money to pay for deficit spending. • The federal government ran significant budget deficits between 1970 and 1997. LO-5 12-44 Budget Surplus • Budget surplus–an excess of government revenues over government expenditures in a given time period: Budget surplus = Government spending < Tax revenues LO-5 12-45 Budget Surplus • By 1998, a combination of growing tax revenues and slower government spending created a budget surplus. • Starting in 2003, however, the budget returned to a deficit due to tax cuts, increased defense spending, and the Iraq War. • By 2010, the federal budget deficit exceeded $1.3 trillion. LO-5 12-46 Countercyclical Policy • In Keynes’ view, an unbalanced budget is perfectly appropriate if macro conditions call for a deficit or a surplus. • A balanced budget is appropriate only if the resulting aggregate demand is consistent with full-employment equilibrium.
