A panel cointegration approach to estimating substitution elasticities in consumption

This paper investigates the relationship between government spending and private consumption. The general framework is a cointegration approach of Ogaki (1992) used to estimate the intratemporal elasticity of substitution between government and private consumption in a panel of 15 European countries. Recently developed non-stationary panel methodologies that assume cross-section dependence are applied. Results indicate an Edgeworth substitutability between private and public spending.     

Non-linear budgetary policies: Evidence from 150 years of Italian public finance

We investigate the sustainability of Italy’s public finances from 1862 to 2012 adopting a non-linear perspective. Specifically, we employ the smooth transition regression approach to explore the scope for non-linear fiscal adjustments of primary surpluses in response to the accumulation of debt. The empirical results show the occurrence of a significantly positive reaction of primary surpluses to debt when the debt–GDP ratio exceeded the trigger value of 110 percent. The after-threshold positive response implies that the path of Italy’s fiscal policy is sufficiently consistent with the intertemporal budget constraint.     

Public debt dynamics with tax revenue constraints

We develop a dynamic model of public debt under the assumption that it is problematic for governments to implement fast increases of tax revenues, as new taxes require costly infrastructure and expertise that can be built only over time. In this environment, the standard condition requiring economic growth greater than interest costs is not sufficient to guarantee financial stability. Debt might become unstable if the gap between these two indicators falls below a given threshold. Our empirical analysis based on historical public finance data for the US provides strong support for the model. This study conveys a cautionary warning, because the debt of relatively safe borrowers may suddenly become unstable for instance because of a substantial deceleration in the growth of nominal income. These issues can be particularly relevant for those countries that do not have a modern and efficient tax collection system.     

A golden rule of public finance or a fixed deficit regime?: Growth and welfare effects of budget rules

In this paper, we compare growth and welfare effects of various budget rules within an endogenous growth model with productive public capital, utility enhancing public consumption and public debt. We find that introducing a fixed deficit regime does not affect the long run growth rate compared to a balanced budget while establishing a golden rule results in higher growth. Simulations of welfare effects indicate that a golden rule leads to highest welfare followed by a balanced budget and a fixed deficit regime. A maximum fraction of deficit financed public investment is derived. Varying the intertemporal elasticity of substitution shows that economies populated by households who have a strong tendency to smooth consumption should adhere to a balanced budget from a welfare point of view.     

An estimated fiscal Taylor Rule for the postwar United States

This paper estimates a multi-instrument fiscal Taylor Rule for the United States. Taxes and purchases both respond strongly to deficits, while transfers do not. Taxes are procyclical; purchases are acyclical; and transfers are countercyclical. These estimates appear stable over time.     

Fiscal policy over the real business cycle: A positive theory

This paper explores the implications of the political economy model of Battaglini and Coate (2008) [8] for the behavior of fiscal policy over the business cycle. The model predicts that fiscal policy is counter-cyclical with debt increasing in recessions and decreasing in booms. Public spending increases in booms and decreases during recessions, while tax rates decrease during booms and increase in recessions. In both booms and recessions, fiscal policies are set so that the marginal cost of public funds obeys a submartingale. When calibrated to the US economy, the model broadly matches the empirical distribution of debt and also its negative correlation with output. However, the predictions of pro-cyclical spending and counter-cyclical taxation do not find empirical support. The calibrated model generates the same fit of the data as a benevolent government model in which the government faces an exogenous lower bound on debt. Nonetheless, the two models have very different comparative static implications.     

Dynamic elasticities of tax revenue: evidence from the Czech Republic

Tax revenue elasticities with respect to tax bases are key parameters for the modeling of public finances. Yet the existing studies estimating these elasticities for emerging countries disregard the effects of tax reforms on tax revenue, which renders their estimates inconsistent. We introduce a framework for estimating both short- and long-run tax revenue elasticities using quarterly data adjusted for the effects of reforms. Our results suggest that the long-run elasticities in the Czech Republic are 1.4 for wage tax, 0.9 for value added tax, 1.7 for profit tax and 1 for social security contributions. The adjustment process for value added tax and social security contributions is fast, but for the remaining two categories, it is important to distinguish between the short- and long-run elasticities: the initial response of revenue to changes in the bases is weak. In the case of wage tax it takes half a year for the elasticity to surpass unity.     

Growth effects of government expenditure and taxation in rich countries: A reply

Agell et al. (2005) criticise our earlier findings (Fölster and Henrekson 2001) of a robust negative relationship between government size and economic growth for an extended sample of rich countries. In this short paper it is argued that their critique is unfounded. Most importantly, the critique does not deal with the main result of the original study, namely that the most complete specifications for assessing the relationship between government expenditure and growth in rich countries are robust even according to stringent extreme bounds criteria.     

Credit and the transmission of fiscal policy shocks: Recent evidence from Greece

Based on the SVAR approach we examine the importance of credit for the transmission of fiscal policy shocks in Greece. Fiscal shocks have more pronounced effects on the output when credit is constrained. Tax burden shocks have the most protracted effects.     

Social polarization, fiscal instability and growth

We present a dynamic model of fiscal policy in a simple growth framework where social polarization (of preferences) plays a central role in the evolution of fiscal instability and growth collapse. In a highly polarized society, a deficit occurs endogenously, fiscal spending path becomes more volatile, output collapses, and economic growth rate is reduced along the transition path to a new lower level of output. One novel feature is that the size of fiscal deficit, the magnitude of fiscal volatility, and the size of reduction in output and growth rate are explicitly shown to be increasing functions of the degree of social polarization. This is because of the positive relationship between the polarization of preferences and the incentive for policymakers (or socio-economic groups) to overexploit the government resources in a common pool setting (polarization effect). Thereby, we offer a fiscal instability channel that negatively links social polarization and growth, which is an alternative yet distinct explanation for the empirical finding that social polarization is harmful to growth. Moreover, we fully distinguish the incentive to engage in such short-term policies under political uncertainty from that under polarization. Polarization and political uncertainty are shown to be distinct yet critical to the dynamic coordination failure in the common pool setting.     

Time-consistent taxation in a dynastic family model with human and physical capital and a balanced government budget

Abstract .  This paper analyzes optimal, time consistent taxation in a dynastic family model with human and physical capital and with a balanced government budget. When tax revenue is used for publicly provided consumption or lump-sum transfers, leisure would be higher than its social optimum. Pareto optimal taxation requires taxing capital income more heavily than labour income and subsidizing investment at the same rate of the tax. Also, it requires either subsidizing labour at the same rate as a consumption tax or subsidizing consumption at the same rate as a labour income tax, and hence it is not a practical guide to policy. Further, a consumption tax, or equivalently a uniform income tax with investment subsidies at the same rate, can be improved on by taxing capital income more heavily than labour income.     

Procyclical government spending: Patterns of pressure and prudence in the OECD

This paper tests for differences in the cyclicality of government spending across functional categories. Evidence from 20 OECD countries suggests that procyclicality is more likely in smaller functional budgets, but capital spending is more likely to be procyclical for the larger spending categories.     

On the size of fiscal multipliers: A counterfactual analysis

We point out that fiscal multipliers derived from SVAR-models include the predicted future path of policy instruments. After the initial shock, net taxes and government expenditures react to each other and are autocorrelated. In a counterfactual simulation, we report fiscal multipliers that abstract from these dynamic responses.     

Beyond the Toledo agreement: the intergenerational impact of the Spanish Pension Reform

The paper examines the intergenerational impact of the Spanish public pension system after the 1997 Pension Reform Act. Within a Generational Accounting framework, we find that the new legal setting could leave future generations with liabilities as high as 176% of 1996 GDP. Hence, we analyse the impact of alternative reforms. Holding the pay-as-you-go setting, a further improvement to tax-benefit linkage in line with the Toledo Agreement proposals is shown to yield an intergenerationally more balanced outcome, than an increase in the retirement age or an expansion of public subsidies financed through indirect taxes. Finally, a move toward a partially funded pension system which restores the intergenerational balance is simulated.     

The distributional impact of large dams: Evidence from cropland productivity in Africa

We examine the distributional impact of large dams on cropland productivity in Africa. As our unit of analysis we use a hydrology based spatial breakdown of the continent that allows one to exactly define regions in terms of their upstream/downstream relationship at a highly disaggregated level. We then use satellite data to derive measures of cropland productivity within these areas. Our econometric analysis shows that while regions downstream benefit from large dams, no beneficial effects accrue to cropland within the vicinity. Moreover, we find that the productivity enhancing impact of upstream dams is dependent on the local climate. Overall our results suggest that upstream dams have quantitatively on average provided up to 12% of the minimum daily per capita amount of kilocalorie needs in downstream communities and increased agricultural production by 1%.     

Nonlinear effects of government debt on private consumption: Evidence from OECD countries

This paper investigates nonlinear effects of government debt on private consumption. The estimated consumption function shows smooth regime switching depending on the debt-to-GDP ratio, and a higher level of government debt crowds out private consumption to a greater extent.
