Primary Surplus Behavior and Risks to Fiscal Sustainability in Emerging Market Countries

This paper proposes a probabilistic approach to public debt sustainability analysis (DSA) using fan charts. These depict the magnitude of risks upside and downside surrounding public debt projections as a result of uncertain economic conditions and policies. We propose a simulation algorithm for the path of public debt under realistic shock configurations, combining pure economic disturbances (to growth, interest rates, and exchange rates), the endogenous policy response to these, and the possible shocks arising from fiscal policy itself. The paper emphasizes the role of fiscal behavior, as well as the structure of disturbances facing the economy and due to fiscal policy, in shaping the risk profile of public debt. Fan charts for debt are derived from the marriage between the pattern of shocks on the one hand and the endogenous response of fiscal policy on the other. Applications to Argentina, Brazil, Mexico, South Africa, and Turkey are used to illustrate the approach and its limitations.

The Discipline-Enhancing Role of Fiscal Institutions: Theory and Empirical Evidence

This paper discusses the role of fiscal institutions, including budget rules and non-partisan agencies, in enhancing fiscal discipline. A dynamic model of fiscal policy shows that optimal institutions lack credibility unless the costs to bypass them are sufficiently high. In our model, a combination of complete budgetary transparency and strong democratic accountability suffice to establish credibility. Under incomplete budgetary transparency, accountable governments may also use institutions as a signal of competence to increase their reelection chances, which in turn erodes the penchant for excessive deficits. In light of the theory, empirical tests of the effectiveness of institutions are undertaken. The results further emphasize that analysis should pay due attention to simultaneity bias (because disciplined governments may be more likely to adopt strict institutions). Also, interactions among different fiscal institutions, and between the latter and key features of the political system need to be explored further.

Reconciling Stability and Growth Smart Pacts and Structural Reforms

This paper analyzes the decision by a government facing electoral uncertainty to implement structural reforms in the presence of fiscal restraints similar to the Stability and Growth Pact. To the extent that the reform package entails budgetary costs, the model shows that a fiscal pact erodes incentives to carry out structural reforms, sacrificing future growth for present stability. Although the pact effectively addresses the deficit bias resulting from electoral uncertainty, the induced reduction in reforms implies ambiguous welfare effects. We conclude that a “smart” (i.e., welfare-improving) pact should take into account the budgetary effects of structural reforms. Our conclusions are consistent with the actual principles guiding the implementation of the Stability and Growth Pact.

FISCAL RULES, FISCAL COUNCILS AND ALL THAT: COMMITMENT DEVICES, SIGNALING TOOLS OR SMOKESCREENS?

Xavier Debrun and Manmohan S. Kumar deal with the impact of institutions on fiscal discipline, first discussing the point in principle: (i) fiscal institutions can work as commitment devices (i.e. tie policymakers’ hands); (ii) they can work as signalling devices (i.e. reduce the information asymmetry between the electorate and policymakers); and (iii) they can be smokescreens. The second part of the paper develops an empirical analysis to test these three hypotheses, referring to descriptive evidence and estimating a multivariate panel model for a large sample of EU countries over the period 1990-2004. The authors use time-varying indices of fiscal rule restrictiveness and coverage. The analysis finds significant support for both commitment and signalling, little for the smokescreen hypothesis.

Fiscal Rules in a Monetary Union: A Short-Run Analysis

This article challenges the conventional result according to which an instrument-independent central bank able to strictly commit to price stability makes fiscal constraints unnecessary. We present a model of a monetary union with heterogeneous members where the inefficient policy mix resulting from the lack of coordination between the common monetary policy and national fiscal policies incites the governments to appoint excessively “liberal” delegates to the central banks board. We characterize the fiscal restraints necessary to restore the central banks ability to deliver the most desirable degree of price stability. It appears that even country-specific and state-contingent restraints may be counterproductive for some member states.

Fiscal Policy and Macroeconomic Stability : Automatic Stabilizers Work, Always and Everywhere

The paper revisits the link between fiscal policy and macroeconomic stability. Two salient features of our analysis are (1) a systematic test for the government’s ambivalent role as a shock absorber and a shock inducer - removing a downward bias present in existing estimates of the impact of automatic stabilizers - and (2) a broad sample of advanced and emerging market economies. Results provide strong support for the view that fiscal stabilization operates mainly through automatic stabilizers. Also, the destabilizing impact of policy changes not systematically related to the business cycle may not be as robust as suggested in the literature.

Government Size and Output Volatility; Should We Forsake Automatic Stabilization?

Prior to the launch of the euro, academics and policymakers were concerned that the loss of the monetary policy instrument would deprive participating countries of a vital tool to respond to country-specific economic shocks. This concern was rooted in the generally accepted proposition that market-based adjustment channels-i.e. labour mobility and capital flows-tended to be weaker among euro area countries than among regions of existing monetary unions such as the United States. Automatic stabilizers had long been regarded as playing a key role in macroeconomic stabilization. In particular, they were generally considered as having contributed significantly to the decrease of output volatility witnessed in Europe and in the United States after World War II, when the size of governments increased substantially on both sides of the Atlantic. Hence it was hoped that improved national fiscal policy could partly make up for the loss of monetary policy in stabilizing national macroeconomic conditions. The aim of the paper is to discuss this issue in the light of recent experience.

Implementing the Stability and Growth Pact; Enforcement and Procedural Flexibility

The paper proposes a theoretical analysis illustrating some key policy trade-offs involved in the implementation of a rules-based fiscal framework reminiscent of the Stability and Growth Pact (SGP). The analysis offers some insights on the current debate about the SGP. Specifically, greater ‘procedural’ flexibility in the implementation of existing rules may improve welfare, thus making the Pact more easily acceptable to euro area Member States. Here, procedural flexibility designates the enforcer’s room to apply well-informed judgment on the basis of underlying policies and to set a consolidation path that does not discourage high-quality policy measures. Yet budgetary opaqueness may hinder the qualitative assessment of fiscal policy, possibly destroying the case for flexibility. Also, improved budget monitoring and greater transparency increase the benefits from greater procedural flexibility. Overall, we establish that a fiscal pact based on a simple deficit rule with conditional procedural flexibility can simultaneously contain excessive deficits, lower unproductive spending and increase high-quality outlays.

Is Fiscal Policy Coordination in Emu Desirable

It is widely argued that Europes unified monetary policy calls for the international coordination at the fiscal level. We survey the issues involved with such coordination of fiscal policy as a demand management tool and we use a simple model to investigate the circumstances under which coordination may be desirable. It turns out that coordination is beneficial when the correlation of the shocks hitting the various economies is low. However, given the potentially adverse reaction by the ECB (as a result of free-riding and/or a conflict on the orientation of the policy mix), fiscal coordination is likely to be counterproductive when demand or supply shocks are highly symmetric across countries and the governments are unable to acquire a strategic leadership position vis-a-vis the ECB.

Making Fiscal Space Happen: Managing Fiscal Policy in a World of Scaled-Up Aid

Debt relief and the scaling up of aid to low-income countries should allow for greater fiscal space for expenditure programs to create long-term growth and lower poverty rates. But designing a suitable medium-term fiscal framework that fosters a sustainable delivery of better public services and infrastructure while maintaining a credible commitment to fiscal prudence confronts many challenges. This paper discusses what low-income countries can do to shape fiscal policy frameworks that are ambitious in trying to absorb additional aid while still ensuring longer-term sustainability for government expenditure programs and finances. It suggests what approaches can be used to manage the greater fiscal policy risks associated with a scaled-up aid environment, including coordination with monetary policy. The paper also discusses what institutional changes are needed if donors and countries are to facilitate the implementation of a higher level of aid-financed spending programs.
