Thorvaldur Gylfason International Monetary Fund/Asian Development Bank Course on Financial Programming and Policies Seoul, Korea, 17-28 May 2010 1. Objectives of fiscal policy Stabilization, allocation, distribution 2. Global financial crisis and fiscal policy response Benefits associated with fiscal policy 3. Risks associated with fiscal policy Public debt dynamics Sustainability of public debt Safeguarding fiscal sustainability 1. The term fiscal policy refers to the use of public finance instruments to influence the working of the economic system to maximize economic welfare 2. Effects of fiscal policy reflect not only the impact of the fiscal balance, but also various elements of taxation, spending, and budget financing 3. Assessing the stance of fiscal policy requires taking account of the activities of all levels of government 1. Stabilization Fiscal policy influences aggregate demand Directly because Y = C + I + G + X – Z Indirectly because C depends on income after tax Through demand, fiscal policy affects output, employment, inflation, balance of payments 2. Allocation Fiscal policy also influences aggregate supply Public infrastructure, education, health care 3. Distribution Through taxes, transfers, and expenditures Progressive, neutral, regressive Fiscal policy can be used to several ends To achieve internal balance To promote external balance By ensuring sustainable current account balance By reducing risk of external crisis To promote economic growth By adjusting aggregate demand to available supply By achieving low inflation, potential output E.g., through more and better education and health care Fiscal policy needs to be coordinated with monetary, exchange rate, and structural – i.e., supply-side – policies Demand management E.g., lower income taxes Price level Aggregate supply in short run B A Aggregate demand Output Demand management Supply management E.g., lower income taxes E.g., lower import tariffs Price level Price level Aggregate supply in short run B Aggregate supply in short run A A Aggregate demand Output B Aggregate demand Output National income accounts Y=C+I+G+X–Z S = Y – T – C = I + G – T + X – Z, so G–T=S–I+Z–X Y = GDP C = Consumption I = Investment G = Government expenditure (plus lending minus repayments) T = Taxes (plus grants) X = Exports Z = Imports B = Government bonds outstanding DG = Credit from banking system DF = Credit from foreigners Government budget deficit must be financed either by (a) having private saving in excess of private investment or (b) by accumulating foreign debt through a deficit in the current account of the balance of payments, or both Alternative formulation G – T = B + DG + DF Government budget deficit must be financed by borrowing either at home or abroad, i.e., from (a) the public, (b) the banking system, or (c) foreigners Central Inflation tax: Most inflationary form of financing Bond bank financing involves money creation finance is less inflationary Removes financial resources from circulation Increases real interest rates Crowds out private investment External Especially if it leads to currency depreciation Evidence financing can be inflationary from cross-country data Strong links between budget deficits and inflation in developing countries, but not in industrial countries Bond finance is the rule in industrial countries … … and money finance is the exception Conventional budget surplus T–G Large in upswings when tax base (Y) is strong Small in downswings when tax base is weak Full-employment surplus TFE – G Use tax revenue as it would be at full employment Independent of business cycles A budget in deficit could be in surplus with full employment Deficit can be consistent with a tight fiscal stance (see chart) T, G T G Y < YFE YFE Y Public sector borrowing requirement Broad measure of public sector deficit, including central, state, and local government Primary budget balance Leaves out interest payments Conventional deficit = G – T = GN + GI – T = GN + iDG - T Primary deficit = GN – T = G – T – iDG GN = Noninterest expenditure GI = Interest expenditure i = Nominal interest rate DG = Government debt outstanding Operational deficit Leaves out inflation component of interest payments Operational deficit = conventional deficit minus inflation component of interest payments = primary deficit plus real component of interest payments GN = Noninterest expenditure Conventional deficit: GI = Interest expenditure N G N G G – T = G + iD – T = G + (r + p)D – T r = Real interest rate DG = Government debt Operational deficit: p = Inflation rate G – T - pDG = GN – T + rDG Hence, operational deficit includes only real part of interest payments, leaves out the inflation part Before Great Depression 1929-39, many thought that governments needed to balance their budgets from year to year Even so, US had built is railways through borrowing, for example Keynes revolted (General Theory 1936) If private sector failed to consume and invest, government could fill the gap Y = C + I + G + X – Z C and I and G appear side by side Guns or butter? Makes no difference Also, could reduce taxes to encourage C and I Multiplier analysis It could be shown that, with unemployed resources, an increase in G would raise Y by an amount greater than the original increase in G Active fiscal policy was used consciously in Sweden even before Keynes … … and adopted in US and elsewhere after 1960 (Kennedy-Johnson administration) Coincided with buildup of US as a welfare state with greater emphasis on public services and social security, like in Europe Active fiscal policy came naturally to Europe Fiscal policy can affect Aggregate demand, output, and price level Cut taxes: Consumption, output, and prices rise Rate of monetary expansion and inflation Increase spending financed by credit expansion: Money expands (M = D + R), so inflation goes up Aggregate supply and economic growth Boost education and health care: Efficiency and long-run growth go up Current account of balance of payments Raise taxes: Disposable income and imports fall, so current account improves unless currency appreciates Fiscal multipliers are positive, but small Impact of fiscal policy actions depends on Whether economy is open or closed (import leakage) Exchange rate regime (fixed or floating) Type of budget financing (money creation or debt) Degree of confidence in economic policy Level of government debt Financing constraints Risk premia on debt Whether fiscal changes are considered temporary or permanent How close the economy is to full employment (-) Gov’t Budget Balance (+) RE (+) (-) Tax revenue (-) Consumption (+) (+) Expenditure (+) Income (+) Fiscal Policy (-) (+) Interest Rate (-) Investment (+) (+) Capital Labor Monetary policy has been used heavily Its further impact may be limited In many countries, policy interest rates already approach zero Monetary policy may have limited effect during “balance sheet recessions,” when many firms are technically bankrupt, will use increased earnings to restore capital, and may not respond to lower interest rates Koo (2009), Holy Grail of Macroeconomics: Lessons from Japan’s Great Recession Mixed evidence on efficacy of fiscal policy in developing countries While automatic stabilizing impulses are weak and make the case for discretion, there is also the widely noted occurrence of pro-cyclicality The focus of stimulus packages differ between advanced and developing countries Infrastructure spending 46% of fiscal stimulus in developing economies, but 15% in advanced economies Tax cuts over 34% of fiscal stimulus in advanced economies, only 3% in developing economies Khatiwada, S. (2009), “Stimulus Packages to Counter Global Economic Crisis; A Review,” International Institute for Labour Studies Discussion Paper 196. No clear consensus among economists about the size of fiscal multipliers (response of real GDP to tax cuts or higher spending) Recent IMF Staff Position Note reports: A rule of thumb is a multiplier (using the definition ΔY/ΔG and assuming a constant interest rate) of 1.5 to 1 for spending multipliers in large countries, 1 to 0.5 for medium sized countries, and 0.5 or less for small open countries. Smaller multipliers (about half of the above values) are likely for revenue and transfers while slightly larger multipliers might be expected from investment spending. Negative multipliers are possible, especially if the fiscal stimulus weakens (or is perceived to weaken) fiscal sustainability.

Fiscal stimulus is assisted by automatic stabilizers Fiscal stimulus packages need to include an exit strategy to ensure that solvency is not at risk, and should Not have permanent effects on budget deficits Provide a commitment to fiscal correction, once economic conditions improve Include structural reforms to enhance growth Should firmly commit to clear strategies for health care and pension reforms in countries facing demographic pressures Need for financing tends to lift interest rates, so capital flows in and currency tends to appreciate Central Bank must offset incipient appreciation by expanding money supply, thereby reinforcing initial fiscal stimulus Otherwise, exchange rate could not remain fixed Need for financing tends to lift interest rates, so capital flows in and currency appreciates Appreciation reduces net exports, aggregate demand, and interest rates Process continues until interest rates fall to their initial level So, fiscal stimulus is ineffective with perfect capital mobility In times of large deficits and growing public debt, public spending can have weak or even negative effects By creating expectations of a fiscal crisis, and hence of higher future taxes Increased saving may lead to a sharp fall in consumption Hence, fiscal stimulus can fail, and may even prove counterproductive Conversely, fiscal contraction may prove expansionary Fiscal policy is frequently key to addressing balance of payments problems Simple mechanism M = R + D means R = M – D = M – DG – DP Hence, given M and DP, key to raising R is reducing DG IMF: It’s Mostly Fiscal! Or look at it this way: Y = C + I + G + X – Z means X–Z=Y–C–T–I–G+T=S–I+T-G Hence, current account balance (X – Z) equals sum of private sector surplus of saving over investment (S – I) and government surplus of taxes over public expenditure (T – G) Equivalently, Z – X = I – S + G – T means that external deficit equals sum of private sector deficit and government budget deficit Unsustainable fiscal policy can trigger a crisis if public loses confidence in government’s macroeconomic policy Sudden capital outflow can result, weakening balance of payments and leading to a sharp devaluation Financing the budget externally builds up external debt, increasing risk of crisis Fiscal sustainability thus matters not only for debt, but also for balance of payments Fiscal contraction (spending cuts, tax increases) can slow down inflation, reduce current account deficit Fiscal expansion (tax cuts, spending increases) can shrink unemployment, increase aggregate demand and help restore output to full capacity, i.e., bring actual GDP up to potential GDP, especially if monetary policy is impotent Automatic, or built-in, stabilizers are revenue or expenditure provisions that have counter-cyclical impact without need for policy intervention Protect against shocks Dampen business cycles Examples Progressive taxes on income, profits Price stabilization funds Unemployment insurance 0 -5 -10 -15 -20 2003 1999 1995 1991 1987 1983 1979 1975 1971 1967 1963 1959 1955 1951 1947 1943 1939 1935 1931 1927 1923 1919 1915 1911 1907 1903 1899 1895 1891 1887 1883 1879 1875 1871 Change in Canada’s per capita GDP from year to year 1871-2003 (%) 20 15 10 5 0 -5 -10 -15 -20 -25 2003 1999 1995 1991 1987 1983 1979 1975 1971 1967 1963 1959 1955 1951 1947 1943 1939 1935 1931 1927 1923 1919 1915 1911 1907 1903 1899 1895 1891 1887 1883 1879 1875 1871 Change in US per capita GDP from year to year 1871-2003 (%) 20 15 10 5 0 -5 -10 -15 1831 1835 1839 1843 1847 1851 1855 1859 1863 1867 1871 1875 1879 1883 1887 1891 1895 1899 1903 1907 1911 1915 1919 1923 1927 1931 1935 1939 1943 1947 1951 1955 1959 1963 1967 1971 1975 1979 1983 1987 1991 1995 1999 2003 Change in UK per capita GDP from year to year 1871-2003 (%) 15 10 5 0 -10 -20 1821 1826 1831 1836 1841 1846 1851 1856 1861 1866 1871 1876 1881 1886 1891 1896 1901 1906 1911 1916 1921 1926 1931 1936 1941 1946 1951 1956 1961 1966 1971 1976 1981 1986 1991 1996 2001 Change in French per capita GDP from year to year 1821-2003 (%) 50 40 30 20 10 0 -10 -20 -30 -40 -50 1851 1855 1859 1863 1867 1871 1875 1879 1883 1887 1891 1895 1899 1903 1907 1911 1915 1919 1923 1927 1931 1935 1939 1943 1947 1951 1955 1959 1963 1967 1971 1975 1979 1983 1987 1991 1995 1999 2003 Change in German per capita GDP from year to year 1851-2003 (%) 20 10 0 1821 1826 1831 1836 1841 1846 1851 1856 1861 1866 1871 1876 1881 1886 1891 1896 1901 1906 1911 1916 1921 1926 1931 1936 1941 1946 1951 1956 1961 1966 1971 1976 1981 1986 1991 1996 2001 Change in Swedish per capita GDP from year to year 1821-2003 (%) 10 5 -5 -10 -15 Source: Maddison (2003). Objections to fiscal activism Borrowing to finance increased government expenditures raises interest rates, thereby crowding out investment and reducing multiplier At full employment, increased public spending, however financed, leads to inflation without stimulating output except temporarily Increasing spending or cutting taxes to combat unemployment may impart inflation bias to economic system Rules vs. discretion Long lags, including approval and implementation Fiscal activism may tend to expand public sector Government has vital role to play in modern mixed economies (allocation role) Education Health care, cf. current debate in United States Infrastructure (roads, bridges, etc.) Some would also stress government’s distribution role … … claiming that the government should try to secure reasonable equality in the distribution of income and wealth, including poverty alleviation Normative or positive economics? Partly positive: Equality is good for growth views Inequality sharpens incentives and thus helps growth Inequality endangers social cohesion and hurts growth 117 countries, 1960-2000 Per capita growth adjusted for intial income (%) Two r = -0.27 6 4 2 0 -2 -4 -6 -8 10 20 30 40 50 60 Gini index of inequality 70 is good for growth No visible sign here that equality stands in the way of economic growth An increase in Gini index by 16 points goes along with a decrease in per capita growth by one percentage point per year Per capita growth adjusted for intial income (%) Equality r = -0.27 6 4 2 0 -2 -4 -6 -8 10 20 30 40 50 60 Gini index of inequality 70 Why not raise government expenditure on public services or whatever and reduce taxes? – to buy votes Supposing all objections could be swept aside Because this would create a deficit and deficits can lead to inflation, and inflation is undesirable for many reasons – it reduces efficiency and growth, for one thing Even so, a modest deficit can be sustained in a growing economy So how modest is modest? Debt accumulation is, by its nature, a dynamic phenomenon A large stock of debt involves high interest payments which, in turn, add to the deficit, which calls for further borrowing, and so on o Debt accumulation can develop into a vicious circle How do we know whether a given debt strategy will spin out of control or not? o To answer this, we need a little arithmetic Revenues Expenditures Budget Deficit Financing Increase in debt Higher interest payments Recall operational budget deficit: G – T = B + DG + DF = D = GN + rD - T where D is total government credit outstanding Further, assume for simplicity T = GN Then, we have D = rD ΔD r This gives D So, now we have: ΔD r D Now subtract growth rate of output from both sides: ΔD ΔY r-g D Y Y g Y But what is ΔD ΔY D Y ? This is proportional change in debt ratio: D Δ ΔD ΔY Y D D Y Y This is an application of a simple rule of arithmetic: %(x/y) = %x - %y z = x/y log(z) = log(x) – log(y) log(z) = log(x) - log(y) But what is log(z) ? dlog(z) dz 1 Δz Δlog(z) dt dt z z So, we obtain Δz Δx Δy z x y Q.E.D. We have shown that Δd rg d where D d Y Debt ratio rg r=g rg Time We have shown that Δd rg d where D d Y Debt ratio rg r=g rg Time We have shown that Δd rg d where D d Y Debt ratio rg r=g rg Time Primary deficit = GN – T = G – T – iDG Primary balance: PB = T – G + iDG Take another look Intertemporal budget constraint: Dt 1 it Dt-1 PBt Dividing by nominal GDP (= PY), we get 1 it Dt Dt 1 PBt PY 1 p t 1 gt Pt 1Yt 1 PYt t t t dt 1 rt d t-1 pbt d t 1 gt dt 1 pbt 1 it 1 rt 1 pt We have seen that 1 rt d t-1 pbt d t 1 gt To find where debt ratio is headed, i.e., the long-run equilibrium value of d, we set dt = dt-1; this gives (1 gt ) pbt dt gt rt > 0 if pb < 0 and g > r Sound fiscal policy is critical for good macroeconomic management, and can help manage capital flows Fiscal stimulus is usually expansionary, but not invariably Fiscal policy crucially affects BOP, and interacts with monetary policy Fiscal policy, as before, is crucial to responding to financial crises Especially when monetary policy lands in liquidity trap and loses traction Fiscal policy can help foster rapid growth
