Discretionary policy in a monetary union with sovereign debt

This paper examines the interactions between multiple national fiscal policymakers and a single monetary policy maker in response to shocks to government debt in some or all of the countries of a monetary union. We assume that national governments respond to excess debt in an optimal manner, but that they do not have access to a commitment technology. This implies that national fiscal policy gradually reduces debt: the lack of a commitment technology precludes a random walk in steady-state debt, but the need to maintain national competitiveness avoids excessively rapid debt reduction. If the central bank can commit, it adjusts its policies only slightly in response to higher debt, allowing national fiscal policy to undertake most of the adjustment. However, if it cannot commit, then optimal monetary policy involves using interest rates to rapidly reduce debt, with significant welfare costs. We show that in these circumstances the central bank would do better to ignore national fiscal policies in formulating its policy.     

The relationship between Turkey’s foreign debt and economic growth: an asymmetric causality analysis

Tackling foreign debt that arises as a result of limited and ineffective use of resources is an item that remains on the agenda particularly for developing countries. In this study, we examine the foreign debt debates to date in terms of economic growth and using the time series for the period 2003Q1 to 2017Q1. We used unit root tests to determine the maximum integration degree of series, and we conducted causality analysis. We found a causality relationship between net foreign debt stock and economic growth in causality analyses performed for Turkey. The empirical results of this study indicate that there is a causality relationship, including both positive and negative aspects, between net foreign debt stock and economic growth. The results of our testing showed a significant causal relationship between the variables.     

Nominal debt as a burden on monetary policy

We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt, until the time inconsistency disappears. There is a resulting welfare loss if debt is nominal rather than indexed. We also analyze the case where monetary policy is time inconsistent even when debt is indexed. In this case, with nominal debt, the sequential optimal policy converges to a time-consistent steady state with positive—or negative—debt, depending on the value of the intertemporal elasticity of substitution. Welfare can be higher if debt is nominal rather than indexed and the level of debt is not too high.     

Is fiscal policy always counter- (pro-) cyclical? The role of public debt and fiscal rules

We investigate the reaction of fiscal policy to the business cycle in a panel of 56 developed, emerging and developing economies over 1990–2011. While we strengthen the established finding that fiscal policy is counter-cyclical, additional outcomes emerge from this study. We reveal a non-linear response of fiscal policy to the business cycle, conditional upon the outstanding debt stock. Interestingly, when the public debt-to-GDP ratio goes beyond our endogenously estimated threshold of 87%, fiscal policy turns pro-cyclical. To tackle this effect, we explore the role of fiscal rules (FR). We unveil heterogeneous impacts among FR, as only some of them may mitigate fiscal policy procyclicality in high-debt contexts.     

Debt sustainability in emerging market countries: Some policy guidelines from a fan-chart approach

This paper uses a probabilistic approach to simulate the medium-term public debt trajectories of several major emerging market countries. We extend the standard debt sustainability analysis framework so as to more faithfully reproduce these countries’ economic reality in two aspects. First, we allow them to differ in the cyclical stance of their fiscal policy and in their degree of fiscal responsiveness to debt. Second, we explicitly integrate the specific risk premium paid by each country when borrowing in foreign currency. It allows us to evaluate the impact of alternative policies that the government may consider to improve sustainability. The results lead to three policy recommendations: i) a country should consider decreasing its exposure to currency risk only in extreme cases (like Argentina); ii) on the contrary, greater fiscal responsiveness (i.e. stronger fiscal tightening whenever there is a debt increase) could enhance sustainability to a much greater extent; iii) countries with low responsiveness to debt or a poor fiscal consolidation track record should be cautious with countercyclical fiscal policies, as they may trigger an unsustainable debt trajectory in the trough of the economic cycle.     

Effects of Eurobonds: A stochastic sovereign debt sustainability analysis for Portugal,Ireland and Greece

This paper assesses the impact of Eurobonds on sovereign debt dynamics for selected European member states (Greece, Ireland and Portugal). For each member state, we produce sovereign debt fan charts of (i) a baseline scenario (no Eurobonds) and (ii) a Full-Fledged Eurobond introduction. The key building blocks of our methodology are (i) a debt framework (which embeds the traditional recursive debt equation), (ii) a vector autoregressive model to take into account and parametrise macroeconomic uncertainty and (iii) a fiscal reaction function. Conditional on the absence of moral hazard, we find Eurobonds to be a good instrument to absorb macroeconomic shocks and to diminish uncertainty over future debt forecasts; for Ireland and Portugal, we find debt to be 20 percentage points lower than under our baseline scenario, by 2020.     

Optimal monetary–fiscal policy in the euro area liquidity crisis

We build an euro-area level DSGE model featuring a liquidity shock in the sovereign bonds market to simulate the strong contraction in economic activity observed during the 2008–2009 crisis. In the model, a sudden deterioration of the liquidity property of sovereign bonds is associated with deep recession and deflation. Against this background we characterize optimal monetary and fiscal policy with full commitment. We find that the optimal policy contains three features: (i) the policy rate is lowered until hitting the zero lower bound (ZLB) and then is kept at the ZLB for more periods; (ii) a prolonged central bank’s balance-sheet expansion aimed at restoring the liquidity deteriorated; (iii) a counter-cyclical fiscal stimulus which offsets, to a large extent, the fall in private spending caused by the liquidity shock. Policy regimes involving (i), but not (ii) and (iii), are quite weak in stabilizing output gap and inflation. Monetary policy regimes such as full inflation-targeting or nominal GDP targeting perform remarkably well insofar as they are complemented with an optimally-implemented counter-cyclical fiscal policy. Our results tend to favour the view that, in case of recession, an euro-wide coordinated fiscal policy should supplement the role of the ECB in achieving its primary objective.     

Austerity,inequality, and private debt overhang

Using panel data of 17 OECD countries for 1980–2011, we find that the distributional consequences of fiscal consolidations depend significantly on the level of private indebtedness. Austerity leads to a strong and persistent increase in income inequality during periods of private debt overhang. In contrast, there are no discernible distributional effects when private debt is low. This result is robust to alternative identifications of fiscal consolidations, to different ways of defining periods of private debt overhang, and to controlling for the state of the business cycle and the level of government debt. We explore different channels through which our findings can be rationalized.     

Policy mix and debt sustainability: evidence from fiscal policy rules

This paper characterizes rules-based fiscal policy setting for G-3 and large EMS countries. We set up a simple fiscal policy rule and then infer on the policymakers’ reaction coefficients by testing with GMM. Our results qualify existing evidence on systematic fiscal policy in two respects. First, fiscal policy usually stabilizes public debt; and there is indeed substantial interaction between fiscal and monetary policies via the policy mix or the debt channel. Second, sustainability is achieved with a “stop–go” cycle of consolidation. Unless debt ratios are high, consolidation does not come at the cost of less cyclical stabilization.     

Sustainability of Austrian public debt: a political economy perspective

Sustainability of Austrian public debt is investigated in the context of political objectives such as stabilizing the business cycle, increasing chances for being re-elected and implementing the ideologies of political parties. Several tests indicate that Austrian fiscal policies were sustainable in the period 1960–1974, while from 1975 on, public debt grew much more rapidly. The development of public debt in Austria seems to be driven not primarily by ideology, but by structural causes and a shift in the budgetary policy paradigm. We find some empirical evidence that governments in Austria dominated by one party run higher deficits than coalition governments. There are no indications of a political business cycle.     

A class of solvable stochastic dividend optimization problems: on the general impact of flexibility on valuation

Summary. We consider the determination of an optimal dividend policy in the presence of cash flow uncertainty and transaction costs. We state a set of weak conditions under which the optimal dividend policy can be explicitly characterized for a broad class of diffusions modelling the underlying cash flow dynamics and demonstrate that increased dividend policy flexibility does not only increase the maximal expected cumulative present value of the future dividends, it also increases the rate at which this value grows (i.e. Tobin’s marginal q). We also prove that increased transaction costs result into larger but less frequent dividend payments.Received: 23 November 2003, Revised: 23 March 2005, JEL Classification Numbers: G35, G31, C44, Q23.Luis H.R.

Fiscal adjustment and the costs of public debt service: evidence from OECD countries

We use a panel of 21 OECD countries from 1970 to 2009 to investigate the effects of different fiscal adjustment strategies on long-term interest rates – a key fiscal indicator reflecting the costs of government debt service. As Europe’s sovereign debt crisis has shown, governments confronted with high deficits and rising debt may be forced to enact fiscal adjustments in order to avoid increasing market pressure and solvency problems. Over the last four decades, such measures taken by governments in OECD countries have varied in duration, size, composition and in their success to re-establish fiscal sustainability. We find that large and expenditure-based adjustments lead to substantially lower long-term interest rates. Small and revenue-based measures do not have an effect on interest rates. Financial markets thus only seem to value strict and decisive measures – a clear sign that the government’s pledge to cut the deficit is credible.     

The sovereign property of foreign reserve investment in China: A CVaR approach

This paper investigates the role of foreign exchange reserve investment to hedge overall macroeconomic risks. Different from usual micro profit-maximizing purpose, the investment with macro objective is unique in the field of foreign reserve investment. We propose a framework of mean-variance-CVaR (conditional value at risk) model to capture the features of such investment and calculate the optimal allocation of foreign reserves in China. We use Cornish–Fisher method to calculate CVaR and adopt quasi-Newton algorithm to solve the optimization problem. Two scenarios are compared in the paper: the usual micro profit-maximizing portfolio and the sovereign portfolio hedging macro risks. We find that hedging the overall macro risks and lower the overall volatility of the economy through foreign reserve investment is possible under certain risk constraints.     

Exploring the link between household debt and income inequality: an asymmetric approach

We investigate the relationship between household debt and income inequality in the USA, allowing for asymmetry, using data over the period 1913–2008. We find evidence of an asymmetric cointegration between household debt and inequality for different regimes. Our results indicate household debt only responds to positive changes in income inequality, while there is no evidence of falling inequality significantly affecting household debt. The presence of this asymmetry provides further empirical insights into the emerging literature on household debt and inequality.     

The response of household debt to income inequality shocks: a heterogeneous approach

This article explores the impact of changes in income inequality on household indebtedness using Pedroni's heterogeneous panel VAR. As a result, we find evidence in support of large cross-country heterogeneity in the responses of household leverage to income inequality shocks. We also find that such heterogeneity stems from differences in the strength of financial regulations and supervision.

Time-varying effects of fiscal policy in Spain: a Markov-switching approach

How have the effects of Spanish fiscal policy varied over time? Given this starting point, in this article we analyse the regime dependence of fiscal policy in Spain by estimating a vector autoregressive model within a Markov-switching framework. Our results indicate that Spain’s membership of the Economic and Monetary Union (EMU) is the most likely source of time variation in the fiscal outcomes. Accordingly, increases in the primary deficit-to-GDP ratio do not succeed in stimulating economic activity in the first regime; rather, unexpected upsurges in the primary deficit harm economic activity (non-Keynesian effect) in the second regime, which prevails since the ratification of the Maastricht Treaty.     

Government risk premiums in the bond market: EMU and Canada

This paper focuses on risk premiums paid by central governments in Europe and sub-national governments in Germany, Spain, and Canada, using data for bond yield spreads for the period 1991–2005. We find that risk premiums by central governments respond positively to debt and deficits; German states enjoyed a favourable position in financial markets before EMU but not thereafter; Spanish and Canadian provinces risk premiums over the whole period; German and Spanish sub-central governments pay liquidity-related interest rate premiums; Canadian and German provinces/states that benefit from fiscal equalization lower spreads. This is evidence of market discipline at work and of credibility of the EU no-bailout clause.     

Minimac : A small integrated model of the financial and real sectors of the Swedish economy

The model emphasizes the financial part of the economy and the channels through which the central bank and the government can affect it. The model combines a complete flow of fund matrix with an income–expenditure scheme in a common framework. The consistency of the flow of funds matrix is achieved through residual determination of one asset/liability from each financial balance identity. The model describes the Swedish credit market after the abolition of credit market regulation. Thus the policy instruments included comprise – among others – the interest rate scale, the cash reserve requirement, the exchange rate, government consumption and differential tax rates but no direct regulation of bank advances or investment in government securities. The model mechanisms are illustrated with policy simulations. Those display, in some instances, processes which after some periods tend to reverse the intended effects of the original policy measure. They therefore point to the need for a strategy which involves a sequential use of several policy instruments.
