  1. Fiscal Policy An Analytical Framework With Application

  2. Outline • Deficits: Definitions and explanations • Fiscal sustainability. What do you want to call fiscal balance? • How should fiscal policy look like in theory? • How does it look in practice?

  3. Deficits: Definitions • Different concepts of Deficit • Full-employment (structural) deficit • Note that the deficit varies with the business cycle • Revenues are greater in expansions • Expenditures are greater in recessions • What would the deficit be if we leave aside these cyclical fluctuations? • In a recession, structural deficit is lower than overall deficit • Primary deficit • Net of interest payments: • Some of the current deficit is simply interest on previously accumulated debt • Credit card again: regardless of what you do this month, you still have to pay interest on your balances

  4. Why Run a Deficit? • Stabilization • Fiscal Policy as a tool to manage AD in the short run • Example: Tax cut • But recall our discussion on the multiplier: What if people look ahead and see that the extra deficit will have to be paid for at some point (with interest!)? • This is often called the “Ricardian” view • “Tax Smoothing” • Even if deficits have no impact on AD, it may still be the case that you want to run them • Taxes have a distortive impact on incentives (i.e. they can affect AS)  The distortion is greater at higher rates • If you have temporary need for high spending, you want to borrow instead of raising taxes

  7. Deficits : Thinking about The Future Burden

  8. Financing a Deficit • Borrowing • If the government needs to incur some expenditure beyond current revenues, it can issue a bond and sell it to the private sector • In other words, it borrows money from the private sector, and pays interest on it • Ex: In the US, government can issue Treasury bill (to be paid back in one year or less), T-note (two to ten years), T-bond (twenty to thirty years) • T-note and T-bond pay interest (“coupon”) every six months; T-bill pays no explicit interest, but is sold at a discount • These bonds are also traded in secondary markets (that’s where the Fed conducts open market operations)

  9. Financing a Deficit • Monetizing • In principle, the government can also sell these new bonds to the Central Bank • To buy them, the CB “prints money” • This form of raising revenue for the government is called “seignorage” • This is a way in which FP can influence MP • Independence of the Central Bank is meant to prevent this type of process

  10. Current Challenges • Current Outlook • Right now, most developed countries are running very high budget deficits • To a large extent, this is a product of the recessions • However, there are structural issues that, if unaddressed, may lead to structurally high deficits, and consequently to increasing (possibly unsustainably so?) debt levels • Demographic issues • Aging  Pensions / Health expenditures • Fewer workers to tax to pay for that • Less private savings (older people save less) • A lot of these are off-budget items

  11. Current Challenges • What Is “Unsustainable”? • Ultimately, it’s about the country’s perceived ability to repay • If investors think they won’t be repaid, they won’t buy bonds • Look at Greece right now • If debt relative to GDP is too high (and rising), the ability to repay may be a concern • But how high is “too high”? • That depends a lot on the situation of each country!

  12. Fiscal sustainability • Debt is accumulated in order to fund a fiscal deficit • The fiscal deficit can be decomposed into three components • Deficit = G – T + i D • Primary spending • Current revenues • Interest on the debt • We do not consider debt issuance or privatization as revenue or debt amortizations as spending • We call T – G the primary surplus, S • Deficit = i D - S • The deficit is just equal to the increase in net debt

  13. Fiscal sustainability • An unsustainable position is one where the debt rises faster than the capacity to pay for it • For debt to be sustainable in the long run, some ratios have to be stable • Debt to GDP • Debt to tax revenue • What needs to be the fiscal balance for this to occur?

  14. Constant debt ratio Consider the following law of motion Where b is the debt to gdp ratio, r is the nominal (real) interest rate, g is the nominal (real) rate of gdp growth and s is the primary surplus. Then b(t) = b(t-1) if:

  15. Numerical examples • A typical tax revenue ratio for an LDC is 15-20 percent • A typical real growth rate is 3-4 percent • A typical debt ratio is 40% of GDP • A typical real interest rate is 5% • The equation implies that the primary surplus needs to be • s=(.05-.03).4=0.8% • So if T/Y = 15%, then G/Y =14.2%

  16. Some fiscal numbers

  17. What happens if the debt is denominated in dollars? Consider the debt ratio Where B* is debt in dollars (tradables) and Y* , Y is tradable and non-tradable output

  18. What happens if there is a real depreciation? The elasticity of b relative to e is given by:

  20. How should fiscal policy look like?

  21. Fiscal policy: Keynesian • Fiscal policy as business-cycle management • Spend in bad times, save in booms • Use fiscal policy when monetary policy is ineffective • Liquidity trap • Japan • Problem: suffers from long and variable lags, but also slow to decide and difficult to change • The problem with the shower temperature

  22. The New Classical critique • People have expectations about the future • The do not see debt as net wealth, since it will be serviced with their own taxes • Ricardian equivalence: an increase in public spending is an increase in future taxes, leading the private sector to spend less in the present • Useless from the point of view of demand management

  23. Ricardian Equivalence • Two periods, no discount rate, r=0 • i=0, rate of discount = 0 • Government consumes always the same amount but taxes only in period 2 • G1=G2=G • Private income is given, Y1, Y2 • 2G= t * Y2 • Y1+(1-t)Y2=C1+C2 • U=u(C1)+u(C2) • C1= C2= [Y1+(1-t)Y2]/2 = [Y1+Y2]/2-G • dC1/dG = -1

  24. A rationale for tax smoothing • Distortionary taxes Y=Y(t), Y’<0, Y’’<0 • E.g. Y1 = Y – at2 • Budget constraint of govt • G1+G2=t1*Y1 + t2 * Y2 • (1-t1)Y1+(1-t2)Y2=C1+C2 • U=u(C1)+u(C2) • C1= C2= [(1-t1)Y1+(1-t2)Y2]/2 • At the optimum t1 = t2

  25. Critique of Ricardian equivalence • Imperfect capital markets in dev. countries • Off-set coefficient: how much does private saving increase when public saving declines? • Standard estimates at 0.5 (Edwards 1996) • But only because of crisis times (Gavin 1997) • In normal times offset is very high • It is very low in bad times • Overlapping generations • I get the money, my children pay the taxes • Exploiting non-equivalence is a weak basis for policy • Tell it to the Republicans

  26. The world is volatile • Y may be volatile because of supply and demand shocks • G may be volatile because programs may have uncertain costs • T depends on Y • G may also depend on Y, ideally with a negative correlation • Unemployment compensation • Automatic stabilizers can do the trick

  27. Optimal policy • Optimal policy: stabilize tax rates in an inter-temporal program that is solvent • How does it look like? • Run deficits in periods of low income • Run surpluses in periods of high income • Make sure that debt ratios remain stationary • Looks keynesian. What is the difference?

  28. Implementing in practice • The OECD calculates the full-employment deficit • They calculate what would have been the deficit if the economy was at the equilibrium Y • Is this appropriate for developing countries?

  29. What would you want to control for in a developing country? • The terms of trade may be at non-equilibrium levels • The current account may be at non-equilibrium levels • Since there is taxation on spending and imports, this may generate a difference of income vis a vis equilibrium • The real exchange rate has important fiscal implications • Calculate FD at equilibrium RER • Are interest rates at equilibrium levels? • Domestic rates and the “peso problem” • Foreign rates are volatile • Old debt may be at different rates than current rates • “Structural fiscal deficit” is where the FD&BB curve cross the NN curve

  37. Questions • Why do developing countries face precarious access to borrowing? • Do they borrow too much? • Do they tax too little? • Why do they exhibit pro-cyclical instead of anti-cyclical fiscal policy? • Why is there an electoral budget cycle?

  38. Why is fiscal policy messy? • Coordination problems • The common pool problem • Delayed stabilization • Aggregation problems • Arrow’s impossibility theorem • Electoral rules • Agency problems • Credibility/time-inconsistency problems

  39. The commons problem • Chicken and lobster • While their benefits tend to be concentrated, they tend to be financed from a common pool of resources • (Weingast, Shepsle and Johnsen 1981) • The budget is the result of a collective decision-making process, involving a variety of agents: • Legislators • Spending ministers • The finance minister • Generates a tendency to overspend and to overborrow

  40. Common pool problems • Dynamic version • Tendency towards pro-cyclical spending

  41. Agency problems • Delegated choice, incompatible objectives and asymmetric information • Governments may want to spend more money than the public, because they can appropriate part of it • Lack of confidence • Incentives to lie about real situation • Incentives to distort reality through policy • E.g. The electoral budget cycle (Nordhaus 1975, Tufte 1978, Rogoff 1990)

  42. Credibility, time inconsistency • What is optimal today is not optimal tomorrow • Let bygones be bygones • Promise to repay in good times is not credible • Imperfect credibility leads to undereborrowing in bad times • Signalling (Saint Paul)

  43. Aggregation and electoral rules • Whose choice is it? • Down to West Palm Beach • Proportional representation vs. first past the post • District magnitude • Margaret Thatcher’s landslide? • What are the costs and benefits • Better representation vs. more difficult aggregation • Effective number of parties • One or two chambers?
