Sovereign default risk premia,fiscal limits,and fiscal policy

We develop a closed economy model to study the interactions among sovereign risk premia, fiscal limits, and fiscal policy. The fiscal limits, which measure the government's ability to service its debt, arise endogenously from dynamic Laffer curves. The state-dependent distributions of fiscal limits depend on the growth of lump-sum transfers, the size of the government, the degree of countercyclical policy responses, and economic diversity. The country-specific fiscal limits imply that the market perceives the riskiness of sovereign debt issued by different countries to be different, which is consistent with the observation that developed countries are downgraded at different levels of debt. A nonlinear relationship between sovereign risk premia and the level of government debt emerges in equilibrium, which is in line with the empirical evidence that once risk premia begin to rise, they do so rapidly. Nonlinear simulations show that fiscal austerity measures that aim to balance the government budget in the short run fail to contain the default risk premium, even with sizeable cuts in government purchases; but a long-term plan for fiscal reform, if it credibly changes the market's expectation about future fiscal policies, can alleviate the rising risk premium.     

Rules and risk in the Euro area

We show that stronger fiscal rules in Euro area members reduce sovereign risk premia, in particular in times of market stress. Using a unique data set of rules-based fiscal governance in EU member states, we estimate a model of sovereign spreads that are determined by the probability of default in interaction with the level of risk aversion. The legal base of the rules and their enforcement mechanisms are the most important dimensions of rules-based fiscal governance.     

Sovereign default and the sustainability risk premium effect

We analyze the joint determination of interest rate risk and debt sustainability for governments with fiscal imbalances. Because higher interest rates imply increased debt services, they worsen the government's financial situation and increase the probability of sovereign default. Thus, higher interest rates eventually lead to a decrease in the real demand for government bonds, which imposes an additional constraint on government debt sustainability.     

Mispricing of Risk in Sovereign Bond Markets with Asymmetric Information

The likelihood that a government will repay its sovereign debt depends both on the amount of debt it issues and on the government's future ability to repay. Whilst the former is publicly observable, the government may have more information about the latter than investors. This paper shows that this asymmetric information problem impairs the market's ability to differentiate economies according to their fiscal sustainability, and can lead to a disconnect between bond prices and default risk. The model can help rationalise the behaviour of Eurozone bond prices prior to the recent European sovereign debt crisis.     

Fiscal limits and monetary policy: default vs. inflation

This paper studies the monetary policy trade-off between low inflation and low sovereign risk in the environment where fiscal authorities fail to fully ensure the sustainability of government debt. Building on the Fiscal Theory of Price Level (FTPL) and the Fiscal Theory of Sovereign Risk (FTSR), this paper differs in its baseline assumption about the monetary policy objective, which is neither to rule out defaults regardless of inflation costs (as in FTPL), nor to follow inflation targeting regardless of associated sovereign risk (as in FTSR). Instead, we study the case in which the central bank controls the risky interest rate to minimize the probability of default while ruling out large inflation hikes. We show that this policy regime can mitigate default risks only when the central bank is expected to allow sufficient increases in inflation. When agents believe that the central bank's tolerance toward inflation hikes has increased, equilibrium risk premium goes down, suggesting that information concerning changes in the central bank's preferences over inflation directly impacts default risks.     

Fiscal decentralization and government size: The role of democracy

This paper examines how the level of democracy in a country affects the relationship between fiscal decentralization and government size. We argue that political regimes, proxied by their democracy levels, are important for different decentralization theories to predict the impact of fiscal decentralization on government size. We test this argument using panel data from 76 developed and developing countries during 1972–2013. We find strong and robust evidence that fiscal decentralization is negatively associated with government size and that a higher level of democracy tends to mitigate the negative impact of fiscal decentralization. Therefore, our study contributes to the literature by offering a novel insight on mixed results regarding the relationship between fiscal decentralization and government size in the literature.     

European policy and markets: Did policy initiatives stem the sovereign debt crisis in the euro area?

We investigate how European policy initiatives influenced market assessments of sovereign default risk and banking sector fragility during the sovereign debt crisis in four adversely affected countries — Portugal, Ireland, Spain and Italy. We focus on three broad groups of policies: (a) ECB policy actions (monetary and financial support), (b) EU programs (financial and fiscal rules as well as financial support in crisis countries), and (c) domestic austerity programs. We measure immediate market impact effects: what policies changed risk perceptions, using CDS spreads on sovereign bonds and banks in this assessment. We employ dynamic panel and event study methodologies in the empirical work. We find that a number of programs initially stabilized sovereign and bank bond markets (e.g. Outright Monetary Transactions program), although announcement and implementation impacts on markets differed in some cases (e.g. second Covered Market Bond Program). Actions designed to shore up sovereign markets often lowered risk assessments in bank bond markets and policies designed to ensure safety and soundness of the European banking system in some cases significantly impacted sovereign debt markets. Finally, a number of policies designed to stabilize markets had surprisingly little immediate impact on either sovereign or bank bond market risk assessments.     

Sovereign Risk,Public Investment and the Fiscal Policy Stance

Of the different types of government outlays, since the 2000s public investment has been the main variable of adjustment during recessions in advanced and emerging economies. These contractions (expansions) have been associated with relatively medium-high (low) sovereign spreads, especially in advanced economies. To rationalize these issues, we develop a model of fiscal policy and sovereign default, with corporate default risk. Policymakers must decide between the provision of an unproductive public good and public investment, weighting their respective net benefits in terms of short-term stabilization and debt sustainability. In our model, investment follows a countercyclical stance only in the case of low levels of debt and moderate negative shocks, and otherwise contracts during recessions. The policy stance, along with the mix between different outlays, is determined by how sovereign risk responds to adverse economic shocks.     

Sovereign bond markets with political risk and moral hazard

A model of interest rates on sovereign bonds with default risk is presented. The model accounts for interaction between interest rates and default risk. Multiple equilibria and stability issues are examined. The model explores the level of debt that markets will tolerate in a context where there is uncertainty about output growth, fiscal discipline, real exchange rates, and IMF intervention. The effect of likely IMF assistance on the debt ceiling is shown to be large.     

Fiscal policy and default risk in emerging markets

Emerging market economies typically exhibit a procyclical fiscal policy: public expenditures rise (fall) in economic expansions (recessions), whereas tax rates rise (fall) in bad (good) times. Additionally, the business cycle of these economies is characterized by countercyclical default risk. In this paper we develop a quantitative dynamic stochastic small open economy model with incomplete markets, endogenous fiscal policy and sovereign default where public expenditures and tax rates are optimally procyclical. The model also accounts for the dynamics of other key macroeconomic variables in emerging economies.     

Does fiscal decentralization mitigate the adverse effects of corruption on public deficits?

Corruption is harmful for public finances and appears closely related to fiscal deficits. We open a new avenue in addressing the effects of corruption on public deficits through fiscal decentralization. For a sample of 31 OECD countries over the period 1986–2010, we find that fiscal decentralization contributes to mitigating the adverse effects of corruption on public deficits. In addition, our findings indicate diversity in the effects of fiscal decentralization, in that it appears related to lower deficits in countries with higher levels of corruption but not in less corrupt countries. Our results suggest that bringing the government closer to the people through fiscal decentralization in relatively corrupt countries leads to more responsible fiscal management.     

Political and Fiscal Risk Determinants of Sovereign Spreads in Emerging Markets

Using a panel of 46 emerging market economies from 1997 to 2008, this paper investigates the key determinants of country risk premiums as measured by sovereign bond spreads. Unlike previous studies, the results indicate that both political and fiscal factors matter for credit risk in emerging markets. Lower levels of political risk are associated with tighter spreads, particularly during financial turmoil. Efforts at fiscal consolidation narrow credit spreads, especially in countries with high initial public debt levels. The composition of fiscal policy also matters as higher public investment lowers spreads as long as the fiscal position remains sustainable and the fiscal deficit does not worsen.     

Fiscal crises,decentralization, and indiscipline

How does fiscal decentralization influence fiscal discipline and the probability of a fiscal crisis? Discrete choice analysis used with panel data reveals that crisis probability is associated positively with spending decentralization and negatively with vertical fiscal imbalance. These effects are prevalent in countries with a higher degree of tax revenue decentralization, while a stronger rule of law mitigates such adverse decentralization effects. The findings imply that reduced risk sharing against local shocks under tax revenue decentralization destabilizes the sustainability of a nation's fiscal system. Therefore, policymakers should be cognizant of the undesirable impacts of decentralization on fiscal crisis and indiscipline.     

Sovereign debt spread and default in a model with self-fulfilling prophecies and asymmetric information

The euro area sovereign debt crisis has renewed interest in government credibility and the risk of default. Recent empirical evidence has shown that the sharp increase in government bond yields cannot be attributed entirely to changes in macroeconomic fundamentals. Contagion effects can occur, and self-fulfilling speculation may arise. In this paper, we develop a theoretical model in the spirit of the second-generation currency crisis models developed by Obstfled (1996). The model describes a strategic game between governments and private investors. Euro area countries face a trade-off as governments may either commit to and implement restrictive fiscal policies or default on debt. The commitment strategy may not be optimal if the fundamentals deteriorate. The policy maker lose part of their credibility, and governments are forced to default. In addition, we introduce uncertainty about the cost of default in the model, which is then able to account for a greater variety of equilibrium. Thus, when the evaluation of the cost of default is asymmetric, prophecies are not always realized and default does not occur. Simulations of the model then show that it offers insights, and can help to account for the situations of Greece and Italy during the sovereign debt crisis.     

A new test for fiscal sustainability with endogenous sovereign bond yields: Evidence for EU economies

In this paper we develop a new test for fiscal sustainability and propose a synthetic fiscal sustainability indicator. Conventional tests based on fiscal reaction functions assume a constant real interest rate. However, many empirical studies find evidence on a positive response of long-term rates to sovereign debt levels. We take this evidence into account and endogenize the long-term real interest rate in testing fiscal sustainability. We apply the new test for the European economies. We find that considering the response of interest rate to debt may change the assessment of fiscal sustainability. More specifically, our results indicate that fiscal sustainability is at risk in a number of European Union economies, even if the results of traditional approaches suggest sustainable fiscal policy.     

Fundamentals and Sovereign Risk of Emerging Markets

We empirically assess the relative importance of various economic fundamentals in accounting for the sovereign credit default swap (CDS) spreads of emerging markets during 2004–2012, which encompasses the global financial crisis of 2008–2009. Inflation, state fragility, external debt and commodity terms of trade volatility were positively associated, while trade openness and a more favourable fiscal balance/GDP ratio were negatively associated with sovereign CDS spreads. Yet the relative importance of economic fundamentals in the pricing of sovereign risk varies over time. The key factors are trade openness and state fragility in the pre‐crisis period, the external debt/GDP ratio and inflation in the crisis period, and inflation and the public debt/GDP ratio in the post‐crisis period. Asian countries enjoy lower sovereign spreads than Latin American countries, and this gap widened during and after the crisis. Trade openness was the biggest factor behind Asia's lower sovereign spreads before the crisis, and inflation during and after the crisis. The results imply that external factors were paramount in pricing sovereign risk prior to the crisis, but internal factors associated with the capacity to adjust to adverse shocks gained prominence during and after the crisis.     

Sudden Stops,Time Inconsistency,and the Duration of Sovereign Debt

We study the sovereign debt duration chosen by the government in the context of a standard model of sovereign default. The government balances off increasing the duration of its debt to mitigate rollover risk and lowering duration to mitigate the debt dilution problem. We present two main results. First, when the government decides the debt duration on a sequential basis, sudden stop risk increases the average duration by 1 year. Second, we illustrate the time inconsistency problem in the choice of sovereign debt duration: governments would like to commit to a duration that is 1.7 years shorter than the one they choose when decisions are made sequentially.     

The effect of political factors on sovereign default

This aricle examines the effect of political factors on sovereign default. Using a theoretical model, we find that political instability increases the likelihood of default. To test this theoretical implication, we use a panel logit model to estimate the effect of long- and short-run political factors, along with other macroeconomic variables, on the probability of default. Data from 68 developed and developing countries between 1970 and 2010 is used to conduct the study. Our findings suggest that a country is more likely to default when (i) it has a relatively younger political regime in place; (ii) it faces a higher chance of political turnover; and (iii) it has a less democratic political system. Economic factors are also vital; a country with stronger growth and less external debt is less likely to experience sovereign default. Robustness tests using alternative measures of political risk, trade balance and EMBI sovereign bond spreads also support the baseline findings.     

Sovereign default risk and volatility

In a model of sovereign debt with endogenous default, we find a non-monotonic relationship between default risk and volatility, reflecting a trade-off between prudence and the insurance value of default. We show that this feature also holds in the data.
