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.     

To react or not? Technology shocks, fiscal policy and welfare in the EU-3

This paper develops a dynamic stochastic general equilibrium (DSGE) model to examine the quantitative macroeconomic implications of counter-cyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity and consumption habits, as the particular market failures justifying policy intervention. We subject the model to productivity shocks and allow policy instruments to react to the output gap and the debt-to-output ratio. A welfare analysis reveals that the most effective instrument-target combination is to use public consumption to stabilize the output gap. Moreover, welfare gains from counter-cyclical fiscal policy are much stronger in the presence of wage rigidities compared with consumption habits. Finally, since active policy and automatic stabilizers are substitutes, it is possible that relatively undistorted economies may be in need of countercyclical fiscal action due to inadequate automatic stabilizers.     

Big Brother is also being watched: Measuring fiscal credibility

Fiscal policy is less credible than monetary policy, due to political economy issues. This paper provides an explicit measure of fiscal credibility, based on the anchoring of private expectations onto official targets. It documents how credibility varied among a sample of 27 European countries over 1995–2019. Credibility behaves like a stock of trust that is affected by fiscal policy, past performance, and institutions (fiscal rules and councils). This paper highlights how regular government communication – budgets and fiscal plans – is crucial to anchor expectations and buttress credibility. Last, it shows that credibility is associated with better sovereign financing conditions. Governments should thus strive to maintain their credibility.     

Identifying fiscal inflation

Fiscal theorists warn about the risk of future inflation as a consequence of fiscal imbalances in the US. Because actual inflation remains historically low and data on inflation expectations do not corroborate such risks, warnings for fiscal inflation are often ignored in policy and academic circles. This paper shows that a canonical NK-DSGE model enables identifying an anticipated component of inflation expectations that is closely related to fiscal policy. Estimation results suggest that fiscal inflation concerns have induced a 1.6%-points increase in long-run inflation since 2001. The model also rationalizes why data on inflation expectations do not reveal such concerns outright.     

The global dimension to fiscal sustainability

This paper provides a new perspective of fiscal sustainability and financial globalization in emerging and industrial countries. We highlight the importance of global capital market shocks for fiscal sustainability, a relationship which has hitherto been ignored in the empirical literature. Using a factor model we demonstrate that the relationship between deficit and debt is conditional upon a global factor and we suggest that this global factor is related to world-wide liquidity. We also demonstrate that this acts as a constraint on emerging market economies’ fiscal policy.     

Monetary–fiscal policy interactions and fiscal stimulus

Increases in government spending trigger substitution effects—both inter- and intra-temporal—and a wealth effect. The ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior. Studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption: higher future taxes create a strong negative wealth effect, while the active monetary response increases the real interest rate. This paper estimates Markov-switching policy rules for the United States and finds that monetary and fiscal policies fluctuate between active and passive behavior. When the estimated joint policy process is imposed on a conventional new Keynesian model, government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized. The paper reports the model's predictions of the macroeconomic impacts of the American Recovery and Reinvestment Act's implied path for government spending under alternative monetary–fiscal policy combinations.     

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.     

Optimal fiscal policy in a world liquidity trap

We construct a model of the international transmission of ‘liquidity trap’ shocks, and examine the case for international coordination of fiscal policy to respond to the liquidity trap. Integrated financial markets tend to propagate liquidity traps. In a global environment, fiscal policy may be effective in raising GDP when the economy is stuck in a liquidity trap, but it does so in a ‘beggar thy neighbor’ fashion; when one economy is in a liquidity trap, the cross country spillover effect of fiscal policy is negative. We examine the welfare optimizing policy response to a liquidity trap when countries coordinate on fiscal policy. Fiscal policy may be an effective tool in responding to a liquidity trap, although it is never optimal to use fiscal expansion sufficiently to fully eliminate a downturn. Moreover, there is little case for coordinated global fiscal expansion. For the most part, the country worst hit by a liquidity trap shock should use its own policies to respond, without much help from foreign policies.     

Cross-border spill-overs from fiscal stimulus in a monetary union

We analyse domestic and cross-border effects of fiscal policy in a two-region business cycle model of a monetary union. Without relying on debt consolidation via spending reversals along the lines of Corsetti, Meier and Mueller (2010) and Corsetti and Mueller (2014) we show that a fiscal expansion by the core economies of the euro area is associated with crowding in of both core and periphery consumption. Interestingly, cross-border spill-over effects are larger the larger the share of credit constrained households in the periphery.     

This time truly is different: The cyclical behaviour of fiscal policy during the Covid-19 crisis

Fiscal policy was more countercyclical during the Covid-19 crisis than in previous (crisis) episodes. This paper presents empirical evidence in favour of a “this time truly is different” moment based on analysing the cyclical behaviour of fiscal policy for 28 advanced economies over 1995–2021. Discretionary fiscal policy during the Covid-19 crisis (2020–2021) did more to counteract the downturn – especially in the Eurozone –, as we do not find comparable evidence for countercyclicality during the financial crisis or Euro crisis. Automatic fiscal stabilisers, the non-discretionary domain of fiscal policy, significantly contributed to countercyclical stabilisation during the pandemic.     

Regime changes and fiscal sustainability in Kenya

Kenya's fiscal policy landscape is characterized by primary deficit spending forcing the government to rely on debt to meet its objectives. The justification often being that as a developing economy, annual growth rates and future prospects may in the short run justify the uptake of debt to finance infrastructural development. However, given potential fiscal limits, fiscal cycles usually alternates between sustainable and unsustainable regimes and this has a bearing on long run sustainability. This study therefore sought to investigate the nature of fiscal policy regime in Kenya and the extent to which fiscal policy is sustainable in the long run taking into account periodic regime shifts. Markov switching models were used to endogenously determine fiscal policy regimes. Regime switching tests were used to test whether No-Ponzi game condition and debt stabilizing condition were met. The results established that regime switching model was suitable in explaining regime sustainable and unsustainable cycles. An investigation of fiscal policy regimes established that both sustainable and unsustainable regimes were dominant, and each lasted for an average of four years. There was evidence to imply the existence of procyclical fiscal policy in Kenya. Regime switching tests for long run sustainability suggested that the No-Ponzi game condition weakly holds in the Kenyan economy. Regime-based sensitivity analysis indicated that persistence of unsustainability regime for more than 4 years could threaten long-run fiscal sustainability.     

Monetary and fiscal policy interactions in a post Keynesian open-economy model

Using a post Keynesian model, this study aims to analyze the stabilizing role of fiscal and monetary policies in an open economy with a managed exchange rate regime. The real exchange rate is modeled as an endogenous variable and inflation explained using the conflicting claims approach. The dynamic properties of macroeconomic equilibrium are evaluated in different regimes of fiscal and monetary policies. The main result of this study suggests that the preferred policy regime is the one in which economic authorities are complementary and fiscal policy plays an explicitly active role. In this regime, the fiscal policy must commit to the target for the rate of capacity utilization and the monetary authority must commit to the inflation target.     

Monetary and fiscal policy interactions in a New Keynesian model with capital accumulation and non-Ricardian consumers

The paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of Ricardian equivalence. Under this assumption, government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics. The key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics. Specifically, we identify bifurcations associated with threshold values of steady-state debt, leading to qualitative changes in the local determinacy requirements.     

Monetary policy and fiscal limits with no-default

This paper discusses monetary and fiscal policy interactions that stabilize government debt. Two distortions prevail in the model economy: income taxes and liquidity constraints. Possible obstructions to fiscal policy include a ceiling on the equilibrium debt-to-GDP ratio, zero or negative elasticity of tax revenues, and a political intolerance of raising tax rates. At the fiscal limit two mechanisms restore solvency: fiscal inflation, which reduces the real value of nominal debt, and open market operations, which diminish the size of government debt held by the private sector. Three regimes achieve this goal. In all regimes monetary policy is passive. In all regimes a muted tax response to government debt is consistent with equilibrium. The propensity of a fiscal authority to smooth output is found to determine what is an acceptable response (in the form of tax rate changes) to the level of government debt, while monetary policy determines the timing and magnitude of fiscal inflation. Impulse responses show that the inflation and tax hikes needed to offset a permanent shock to transfers are lowest under nominal interest rate pegs. In this regime, most of the reduction in the real value of government debt comes from open market purchases.     

Cross-country evidence on the distributional impact of fiscal policy

This article provides new evidence on the distributional effects of fiscal policy using data on a panel of OECD economies over the last four decades. We study how four measures of income inequality and poverty respond to several stock and flow variables accounting for fiscal actions. We find that increases in government debt and expenditure promote a less unequal distribution of income. We detect a significant distributional impact of education and social spending as well as of government consumption expenditure. We also investigate potential redistributive implications of large fiscal expansion and consolidation episodes finding no evidence of additional effects beyond those associated with conventional fiscal variables.

Cross-country evidence on determinants of fiscal policy effectiveness: the role of trade and capital flows

This article studies the determinants of size differentials between fiscal multipliers in countries around the world, both advanced and developing economies. We introduce variables not considered before for explaining multiplier size differentials, such as capital flows and the openness of capital markets, while controlling for domestic conditions and exchange rate regimes. We also disaggregate GDP into its main components in order to identify the channels through which external and internal factors can influence GDP after a change in fiscal policy. Our results point to the existence of a new channel through which fiscal policy effectiveness is affected. Capital flows, especially FDI flows, play an important role in determining the sizes of fiscal multipliers, and a country’s external conditions largely explain GDP changes after fiscal expenditure shocks. Our results also point towards a strong link between a country’s international position and its real economy.     

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.     

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.     

Capital inflows, fiscal discretion, and exchange rate policy

Many writers have argued for the benefits of a credible fixed exchange rate (a hard peg) as a commitment device in an open economy. But historically, fixed exchange rates have often been associated with large current account deficits and episodes of ‘over-borrowing’. This paper develops a model of capital inflows that are linked to the exchange rate regime because of endogenous fiscal policy. The key message of the paper is that a hard peg is undesirable in the absence of commitment in fiscal policy. In face of a credible fixed exchange rate, the fiscal authority subsidizes capital inflows. The economy will engage in inefficiently high international borrowing, and in welfare terms may end up worse off than under capital market autarky. To eliminate the incentive to subsidize borrowing, the monetary authority must follow a flexible exchange rate rule in which capital inflows lead to exchange rate appreciation. If fiscal policy must be financed by money creation rather than direct taxation, then a fixed exchange rate rule may cause both over-borrowing and a subsequent exchange rate crisis.     

Macroeconomic impacts of fiscal policy shocks in the UK: A DSGE analysis

This paper develops and estimates a new-Keynesian dynamic stochastic general equilibrium (DSGE) model for the analysis of fiscal policy in the UK. We find that government consumption and investment yield the highest GDP multipliers in the short-run, whereas capital income tax and public investment have dominating effect on GDP in the long-run. When nominal interest rate is at the zero lower bound, consumption taxes and public consumption and investment are found to be the most effective fiscal instruments throughout the analysed horizon, and capital and labour income taxes are established to be the least effective. The paper also shows that the effectiveness of fiscal policy decreases in a small open-economy scenario and that nominal rigidities improve effectiveness of public spending and consumption taxes, whereas decrease that of income taxes.
