I. Motivation
Empirical evidence shows that Fiscal policy is procyclical in Latin America
–During expansions (contractions)
•cyclically-adjusted revenues decrease (increase)
•cyclically-adjusted expenditures increase (decrease)
–Gavin and Perotti (1997), Alberola and Molina (2003)
–Widespread phenomenon:
• Talvi and Vegh (2000) show that FP is procyclical in a sample of 20 industrial countries and 36 developing countries. Exception: G-7 countries.
•Kaminsky, Reinhart and Vegh (2004) for a sample of 104 countries.
Destabilizing role of fiscal policy
– introduces an additional source of volatility.

I. Motivation
Does the stance of fiscal policy depend on creditworthiness, as measured by debt sustainability perceptions?
Empirical strategy1) Test the procyclicality of FP in LA
•Compute output gap and structural primary balance (SPB)
•Are they correlated?
2) Test how perceptions of credit worthiness, embedded in debt sustainability impinges on fiscal stance
•Derive indicator of debt sustainability : current threshold balance (CTB)
•Estimate relationship between fiscal stance and CTB
6
II. Procyclicality of Fiscal Policy
Three steps:
Derive the output gap
Estimate the structural balance–Fiscal Stance= change of SPB as percentage of GDP
SPB associated with cyclically-adjusted revenuespublic spending
contractionary fiscal stance
Is Fiscal policy procyclical?
Test link SPB changes and output gap

II. Procyclicality of Fiscal Policy: Output Gap
OUTPUT GAP
– Production function: OECD, IMF (EC shifting towards it)•Problems: data availability (labour stock, capacity use, K stock), data homogeneity, crises and volatility
– Modified Hodrick-Prescott Filter (Kaiser and Maravall, 1999)
•Pre-adjust the series by removing outliers ==> tackle sharp drops in activity•To overcome accuracy problems in both ends of the series we added forecasts and backcasts (actually, original series for backcasts and Consensus Forecasts for forecasts)

II. Procyclicality of FP: Structural Primary Balance
STRUCTURAL PRIMARY BALANCE
Simplified scheme differs from OECD
Cycle sensitive revenues, considered as a whole (no data) Expenditure not depending on cycle (no unemployment benefits) Account for the importance of commodity-related taxes:
OIL: Colombia, Ecuador, Mexico and Venezuela; COPPER: Chile
9
II. Procyclicality of FP: Structural Primary Balance
1.- Revenue elasticities wrt GDP and commodity prices
2.- Structural component of public revenues:
where both Y* and P* are estimated by applying the Modified H-P filter
3.- Structual Primary Balance (SPB, henceforth):

II. Procyclicality of FP: Structural Primary Balance
Sample:Period: 1980-2004
Countries: Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, Uruguay and Venezuela
Sources: IMF’s GFS and IFS complemented with national statistics
Caveat: fiscal data is for the central government, except for the public debt, which is for the consolidated government

III. Debt sustainability and Fiscal Stance
Why is fiscal policy procyclical? We focus on sustainability concerns
impinge on perception of credit worthines are reflected on financial indicators
Financial indicators coupled with debt level determine debt dynamicsDebt dynamics signal debt sustainability and therefore concernsThe level of debt is binding through the cycle if
High enoughFinancing conditions are volatile and
closely related to the cycle affect debt sustainability concerns
Putting these intuitions into testing:1.- Derive an indicator of fiscal sustainability: current threshold balance2.- CTB v. Fiscal Stance
16
III. Debt sustainability and Fiscal Stance: CTB
1. CURRENT THRESHOLD BALANCE (CTB) Starting point: government’s budget constraint (%GDP)
Simplifying assumptions due to data availability: contingent liabilities, types of debt, seignorage
Hence, current threshold balance = debt-stabilising primary balance (D=0)
Note: no distinction internal/external debt, equal cost We use a measure of implicit real interest rate derived from dividing
interest payments over the stock of debt, both as %GDP Overcome problems linked to that simplification

III. Debt sustainability and Fiscal Stance: SPB vs CTB
2. DOES THE FISCAL STANCE DEPEND ON DEBT SUSTAINABILITY CONCERNS?
Empirical analysis framed within the following regression:
CTB expected positive sign– Higher required primary balance triggers fiscal contraction (SPB)
FP reaction to sustainability concerns is expected to be a function of the sustainability problem itself
– Larger gap, more impact on changes in SPB expected negative sign– More evident impact of CTB on SPB
Controls: inflation, terms of trade, output gap, years-in-default dummies

IV. Conclusions
We have presented robust evidence on
Fiscal policy in Latin America is procyclical
This procyclicality is shown to be related to the evolution of fiscal sustainability
–Deterioration of fiscal sustainability indicator, as measured by the CTB, leads to a fiscal tightening
–The tightening is larger the worse is the level of debt sustainability, as measured by the ECM term
–Once we control for debt sustainability fiscal policy is neutralExtensions
–Normative consequences. Is fiscal policy adequate?•Long term values of debt dynamics determinants
–Why not doing it for CA + R.D?
