Growth and Public Debt: What Are the Relevant Trade‐Offs?

The interplay between growth and public debt is addressed considering a Barro‐type (1990) endogenous growth model where public spendings are financed through taxes on income and public debt. The government has a target level of public debt relative to GDP, and the long‐run debt‐to‐GDP ratio is used as a policy parameter. We show that when debt is a large enough proportion of GDP, two distinct balanced‐growth paths (BGPs) may coexist, one being indeterminate. We exhibit two types of important trade‐offs associated with self‐fulfilling expectations. First, we show that the lowest BGP is always decreasing with respect to the debt‐to‐GDP ratio while the highest one is increasing. Second, we show that the highest BGP, which provides the highest welfare, is always locally indeterminate while the lowest is always locally determinate. Therefore, local and global indeterminacy may arise and self‐fulfilling expectations appear as a crucial ingredient to understand the impact of debt on growth, welfare, and macroeconomic fluctuations. Finally, a simple calibration exercise allows to provide an understanding of the recent experiences of many OECD countries.     

Testing for a Debt‐Threshold Effect on Output Growth

Using the Reinhart–Rogoff dataset, we find a debt threshold not around 90 per cent but around 30 per cent, above which the median real gross domestic product (GDP) growth falls abruptly. Our work is the first to formally test for threshold effects in the relationship between public debt and median real GDP growth. The null hypothesis of no threshold effect is rejected at the 5 per cent significance level for most cases. While we find no evidence of a threshold around 90 per cent, our findings from the post‐war sample suggest that the debt threshold for economic growth may exist around a relatively small debt‐to‐GDP ratio of 30 per cent. Furthermore, countries with debt‐to‐GDP ratios above 30 per cent have GDP growth that is 1 percentage point lower at the median.     

Sovereign default risk and state-dependent twin deficits

This paper analyzes the impact of the government debt-to-GDP ratio on the correlation of the fiscal balance and the current account. Above a government debt-to-GDP ratio of 90 percent the correlation of the two balances decreases by 0.16 in a sample of 12 euro area countries and by 0.17 for Greece, Ireland, Portugal and Spain. This paper develops a small open economy model with defaultable government debt and riskless international capital markets to explain the empirical evidence of a state-dependent change in the correlation. In the model high public debt-to-GDP ratios raise sovereign risk premia as the default probability increases, leading to higher uncertainty about future taxes. In this case precautionary savings of households increase and partially compensate current account deficits that result from fiscal deficits. The increase in households' saving reduces the correlation of the two balances by the same magnitude as documented in the data. The model calibrated to Greece matches further business cycle moments and the empirical default frequency.     

Fiscal consolidations and bank balance sheets

We empirically investigate the effects of fiscal policy on bank balance sheets, focusing on episodes of fiscal consolidation. To this aim, we employ a very large data set of individual banks' balance sheets, combined with a newly compiled data set on fiscal consolidations. We find that standard capital adequacy ratios such as the Tier-1 ratio tend to improve following episodes of fiscal consolidation: for the median bank in our sample, a 1% of GDP fiscal consolidation increases the Tier-1 capital ratio by around 1.5 percentage points over two years. Our results suggest that this improvement results from a portfolio re-balancing from private to public debt securities which reduces the risk-weighted value of assets. In fact, if fiscal adjustment efforts are perceived as structural policy changes that improve the sustainability of public finances and, therefore, reduce credit risk, the banks' demand for government securities should increase relative to other assets.     

Long‐Term Effects of Fiscal Policy on the Size and Distribution of the Pie in the UK*

This paper provides a joint analysis of the output and distributional long‐term effects of various fiscal policies in the UK, using a vector autoregression (VAR) approach. Our findings suggest that the long‐term impact on GDP of increasing public spending and taxes is negative, and especially strong in the case of current expenditure. We also find significant distributional effects associated with fiscal policies, indicating that an increase in public spending reduces inequality while a rise in indirect taxes increases income inequality.     

Spending Reversals and Fiscal Multipliers under an Interest Rate Peg

This paper examines whether fiscal stimuli are more effective when the monetary policy is less responsive to inflation. First, we provide empirical evidence suggesting that, in the period of U.S. passive monetary policy, a positive government spending shock was followed over time by a spending cut. Second, our theoretical analysis reveals that the pegged nominal interest rate is not a sufficient condition to generate a large fiscal multiplier. An increase in government spending could increase the long‐run real interest rate, if it is associated with a government spending reversal and a less responsive monetary policy. Consequently, the response of private consumption can be negative and the government spending multiplier is not necessarily greater than 1.     

防控“新冠肺炎”疫情的财税政策研究

突如其来的“新冠肺炎”疫情对我国宏观经济的平稳运行特别是对中小企业的经营以及就业都会产生较大的影响。在这场防控疫情的斗争中,财政税收政策将发挥重要的作用,但无论是减税还是增支都将会加大财政的赤字率。在2020年这个特殊时期,国家可以考虑突破3%的财政赤字率,但从长期来看,未来也不应该搞结构性赤字,因为这将导致巨大的政府债务。为了应对疫情,国家应当在加大宏观政策调节的力度、加大对公共卫生领域的投入、缓解企业经营困难以及实施好就业优先政策方面出台相应的财税政策。     

Austerity and Private Debt

This study provides empirical evidence that the costs of austerity crucially depend on the level of private indebtedness. In particular, fiscal consolidations lead to severe contractions when implemented in high private‐debt states. Contrary, fiscal consolidations have no significant effect on economic activity when private debt is low. These results are robust to alternative definitions of private‐debt overhang, the composition of fiscal consolidations, and controlling for the state of the business cycle and government debt overhang. I show that deterioration in household balance sheets is important to understand private debt‐dependent effects of austerity.     

Fiscal Fan Charts: A Tool for Assessing Member States' (Likely?) Compliance with EU Fiscal Rules

This paper sets out a methodology for constructing fan charts for the government deficit and debt ratios over the medium term. It relies on information contained in Stability/Convergence Programme Updates, a model of the relevant stochastic process (for example, that of real GDP) or processes, and a parameter estimate of the sensitivity of the primary budget balance to the output gap for the member state under consideration. A model of the dynamic deficit–debt relationship allows the impact of random output growth to work its way through the fiscal arithmetic in a consistent and traceable way to produce fan charts over a five‐year forecast horizon. The initial set of fiscal fan charts included here for Ireland use the indicative public finance projections set out in its 2011 Update. The methodology makes the standard assumption of no fiscal policy response to any change in the budgetary position over the period such as could arise from changes in growth rates. Governments will, however, generally be in a position to adjust fiscal policy towards meeting a specific target, such as the 3 per cent Maastricht Treaty deficit target. A second set of fan charts is included that indicates how the probabilistic range of fiscal outcomes could be affected by a tightening of fiscal policy in 2013–15.     

Canada's Budget Triumph

In the mid‐1990s Canada's federal government, concerned about a debt‐to‐GDP ratio that was approaching 70%, began a decade‐long policy of cutting government spending. It also increased taxes, but by only one dollar for about every six dollars of spending cuts. The Canadian government cut subsidies to individuals, corporations, and provincial governments while tightening eligibility for unemployment insurance. The government also sold off its holdings of various state‐owned enterprises. One major success was its shifting of air traffic control to NAV Canada, a private, non‐profit user cooperative. This step netted the government $1.4 billion at the outset, saved about $200 million a year in subsidies, and resulted in a technological revolution in air traffic control that has put Canada years ahead of the United States. From 1997 to 2008, Canada's government had an unbroken string of annual budget surpluses; and by 2009, Canada's debt‐to‐GDP ratio had fallen below 30%. Starting in 2000, the government used some of what otherwise would have been surplus to cut taxes on individuals and corporations. The corporate tax rate was cut in stages from 28% in 2000 to 21% by 2004.

Macroeconomic Effects of Government Spending: The Great Recession was (Really) Different

We estimate the effect of government spending shocks on the U.S. economy with a time‐varying parameter vector autoregression. The recent Great Recession period appears to be characterized by uniquely large impulse responses of output to fiscal shocks. Moreover, the particularity of this period is underlined by highly unusual responses of several other variables. The pattern of fiscal shock responses neither completely fits the predictions of the New Keynesian model of an economy subject to the zero lower bound on nominal interest rates, nor does it suggest regular variation of fiscal policy effects depending on the state of the business cycle. Rather, the Great Recession period seems special in that government spending shocks had a strongly negative effect on the spread between corporate and government bond yields and a strongly positive effect on consumer confidence and private consumption spending.     

Financial Crisis, Fiscal Policy, and the 1995 GDP Contraction in Mexico

In 1995 Mexico experienced its largest contraction of gross domestic product (GDP) since the early twentieth century. I propose a simple mechanism to partially account for the contraction: the effects of changes in fiscal policy. The contraction of GDP was preceded by a financial crisis. The government responded by raising taxes and reducing spending. Using a model with taxation and government consumption, and the business cycle accounting methodology, I measure the impact of fiscal policy. Fiscal policy accounts for 20.7% of the fall in output.     

Fiscal Policy Shocks in the Euro Area and the US: An Empirical Assessment*

We analyse the impact of fiscal policy shocks in the euro area as a whole, using a newly‐available quarterly data set of fiscal variables for the period 1981–2007. To allow for comparability with previous results on euro‐area countries and the US, we use a standard structural vector autoregressive (VAR) framework, and study the impact of aggregated and disaggregated government spending and net‐tax shocks. In addition, to frame euro‐area results, we apply the same methodology for the same sample period to US data. We also explore the sensitivity of the results to the inclusion of variables aiming to control for underlying financial and fiscal conditions. The main new findings are that: expansionary fiscal shocks have a short‐term positive impact on GDP and private consumption, with government spending shocks entailing, in general, higher effects on economic activity than (net) tax reductions; output multipliers to government expenditure shocks are of similar size in the euro area and in the US; the persistence of a fiscal spending shock is higher in the US than in the euro area, which appears to be related to military spending in the US; and fiscal multipliers have increased over the recent past in both geographical areas.     

Is fiscal consolidation self-defeating? A panel-VAR analysis for the Euro area countries

This paper studies the effects of fiscal consolidation on the debt-to-GDP ratio of 11 Euro area countries over the period 2000Q1-2012Q1. Using a quarterly Panel VAR allows us to trace out the dynamics of the debt-to-GDP ratio following a fiscal shock and to disentangle the main channels through which fiscal consolidation affects the debt ratio. We define a fiscal consolidation episode as self-defeating if the level of the debt-to-GDP ratio does not decrease compared to the pre-shock level. Our main finding is that when consolidation is implemented via a cut in government primary spending, the debt ratio, after an initial increase, falls to below its pre-shock level. When instead the consolidation is implemented via an increase in government revenues, the initial increase in the debt ratio is stronger and, eventually, the debt ratio reverts to its pre-shock level, resulting in what we call self-defeating consolidation.     

Macro‐Fiscal Volatility and the Composition of Public Spending*

Earlier empirical literature has examined some long‐ and medium‐term aspects of macro‐fiscal volatility while leaving its short‐term fiscal impact unexplored. To help fill that gap, we examine the impact of macro‐fiscal volatility on the composition of public spending. To that end, we analyse a panel of 10 EU countries during 1991–2007. Our results suggest that increases in the volatility of regularly‐collected and cyclical revenues such as the VAT and income taxes tend to tilt the expenditure composition in favour of public investment. In contrast, increases in the volatility of ad hoc taxes such as capital taxes tend to favour public consumption spending, albeit only a little. We interpret such volatility innovations as conveying news to the fiscal policymaker about the underlying economic conditions, with especially regularly‐collected and cyclical taxes prompting short‐term cyclical fine‐tuning.     

Fiscal consolidations and public debt in Europe

The objective of this paper is to gain insights into the relationship between deficit-reducing policies and the evolution of the debt/GDP ratio. We consider past events of fiscal consolidation in a selected group of EU countries and check what is the associated change of the debt/GDP ratio both from a short- and medium-term perspective. In the analysis, we also differentiate between tax-based and savings-based fiscal consolidations and the pre-Euro and Euro periods. Our results point towards a positive short-term effect, while the medium-term effect turns out to be negative. Savings-based fiscal consolidations result to be less negative on the DGR evolution than tax-based ones. The Euro’s introduction seems not to have altered significantly the relationship studied.     

Outside wealth,the demand for money and the crowding out effect

Policy simulations with most large macroeconometric models evidence little, if any, crowding out of private spending from debt financed increases in government expenditures. Examination of the structure of these models reveals that none allows for a wealth effect of debt finance on the demand for money, even though theoretical studies suggest that this wealth effect may cause significant crowding out. This paper provides empirical evidence that increases in government debt held by the public do increase the demand for money; therefore, the fiscal policy simulations of the large macroeconometric models may yield biased conclusions concerning the crowding out effect.     

On the International Dimension of Fiscal Policy

This paper analyzes the international dimension of fiscal policy in a small open economy framework. We consider the case in which the government finances its spending by levying distortionary taxes and issuing state‐contingent debt. While in a closed economy taxes are essentially invariant, in an open economy taxes can be as volatile as output. This is because the presence of a terms of trade externality introduces efficient fluctuations in the consumption–leisure wedge driven by movements in the real exchange rate. As a result, the optimal fiscal rule suggests that taxes should be varied to replicate these fluctuations.     

Identifying Discretionary Fiscal Policy Reactions with Real‐Time Data

We propose a method of identifying discretionary fiscal policy reactions using real‐time data. Automatic stabilizers should depend on true GDP, while discretionary fiscal policy is contingent on the information that policy makers have in real time. We can compute a real‐time measurement error by comparing the first release of GDP data with later revisions. Discretionary fiscal policy is influenced by this measurement error, whereas automatic fiscal policy is not. We use this identification approach to test the central identifying assumption of Blanchard and Perotti’s (2002) seminal structural vector autoregression (VAR). According to this assumption, fiscal policy makers do not react to GDP developments contemporaneously in a discretionary fashion. We find that government expenditure is adjusted upward if GDP growth in real time is lower than true GDP. This suggests that fiscal policy makers use short‐term funds to buy goods and services in response to their perception of GDP dynamics.
