Variation in the fiscal multiplier with the method of financing: evidence across industrial countries

Government spending has often varied with the business cycle to stimulate the economy and to revive economic conditions. However, the state of public finances has often necessitated higher borrowing to finance widening fiscal deficits. Indeed, recent austerity packages around the globe have crystalized the importance of fiscal consolidation against the backdrop of rising public debt. To shed light on recent debates regarding fiscal multipliers, the article estimates variation in these multipliers with the method of financing, using annual data for a sample of industrial countries. There is a large variation in the effects of expansionary and contractinary government spending shocks on economic variables within and across countries. The significant effects of negative government spending shocks (fiscal contraction) appear more prevalent than those of expansionary shocks on real output growth, price inflation and nominal wage inflation. Consistent with theory’s predictions, the fiscal multiplier is more likely to be negative when government spending is financed by issuing debt and less likely in the case of monetization. The evidence confirms concerns about the negative effect of higher debt and more expensive financing on private activity, countering the effectiveness of fiscal policy.     

政府债务会影响财政支出的乘数效应吗?—来自跨国面板数据的经验证据

文章在构建一个局部均衡模型的基础上,采用150个国家(地区)2000?2014年的面板数据,实证考察了政府债务对财政支出乘数效应的影响,得到了与理论预期一致的经验证据.结果表明:(1)政府债务会显著影响财政支出的乘数效应.随着政府债务水平的提高,财政支出的乘数效应趋于减弱.尤其是在克服内生性问题之后,这一结论仍然成立;(2)政府债务作用存在显著的非线性特征.当政府债务占GDP的比重突破88%的阈值后,财政支出的乘数效应会在低债务国家和高债务国家之间发生非常迅速的逆向转换;(3)对中国这样的低债务国家,顺周期的财政政策运用是非常有效的.而对美国、希腊等已经处于高债务水平的国家,采取逆周期的财政政策才能避免潜在的经济波动风险.     

Government debt and optimal monetary and fiscal policy

How do different levels of government debt affect the optimal conduct of monetary and fiscal policies? And what do these optimal policies imply for the evolution of government debt over time? To provide an answer, this paper studies a standard monetary policy model with nominal rigidities and monopolistic competition and adds to it a fiscal authority that issues nominal non-state contingent debt, levies distortionary labor income taxes and determines the level of public goods provision. Higher government debt levels make it optimal to reduce public spending, so as to dampen the adverse incentive effects of distortionary taxes, but also strongly influence the optimal stabilization response following technology shocks. In particular, higher debt levels give rise to larger risks to the fiscal budget and to tax rates. This makes it optimal to reduce government debt over time. The optimal speed of debt reduction is missed when using first-order approximations to optimal policies, but is shown to be quantitatively significant in a second-order approximation, especially when technology movements are largely unpredictable in nature.     

Government debt,inflation dynamics and the transmission of fiscal policy shocks

We analyze the influence of the fiscal position on the transmission of government spending shocks in a New Keynesian model. We find that once we allow for positive levels of government debt in the steady state, the size of the fiscal multiplier depends strongly on the horizon at which the multiplier is evaluated. While the long-run effect of a fiscal policy innovation is typically of a similar order of magnitude as in Galí et al. (2007), short-run multipliers differ substantially. The reason for this non-monotonic behavior is the interaction between the dynamics of the inflation rate and the debt level in real terms for sufficiently high levels of government debt in the steady state.     

SHOULD WE CARE ABOUT THE COMPOSITION OF TAX‐BASED STIMULUS PACKAGES?

We investigate the effects of tax policy shocks on the U.S. economy over the 1972:3–2008:4 period within a structural vector autoregressive (SVAR) framework. Disaggregating tax shocks suggests that the positive output multipliers documented for total taxes by the previous literature are present only for indirect tax innovations. We also show that both labor and corporate taxes have similar effects on output, with labor tax multipliers being slightly larger in magnitude. The positive and negative responses of inflation following respectively corporate and labor tax shocks imply that former shocks work through aggregate supply, whereas the latter work predominantly through aggregate demand.

Growth forecast errors and government investment and consumption multipliers

We compare government investment and consumption multipliers in developed economies during the initial years of the ongoing fiscal consolidation. We find that, in countries with high public debt, the investment multiplier is likely to be higher than what has been assumed by policy-makers and higher than the consumption multiplier. This leads to the conclusion that the consolidation should be accompanied by increased public investment.     

Fiscal policy and national saving

This paper uses structural vector autoregressions along with structural measures of fiscal policy to measure the dynamic impact of fiscal policy shocks on the output gap and national saving. Positive shocks to government purchases and negative shocks to real net taxes are found to increase the output gap. Positive shocks to the government's structural surplus increases national saving although the effects are small. Positive shocks to government purchases are found to substantially reduce national saving. Negative shocks to real net tax revenues as a share of potential GDP have a small negative impact on national saving.     

Fiscal policy in a small open economy with cross-border labor mobility

The large and stable inflow of workers’ remittances through formal financial channels to developing countries prompted authorities to harness fiscal resources from this flow. This paper develops a macro-dynamic model of a small open economy with cross-border labor mobility emphasizing fiscal policy. The flow of remittances is the result of a household’s optimizing decision to migrate. We examine the macroeconomic responses to fiscal policies. First, we show that an economy with international migration is more resilient to demand shocks resulting from fiscal contraction. Second, the short-run association between remittances and domestic output depends on the sources of the shocks. Third, our results indicate that the equilibrium impact of a tax on remittances can be expansionary and welfare-improving when an economy is initially close to full employment. The presence of utility-enhancing government expenditure and a potential negative externality from over-allocation of labor abroad (over migration) justify the presence of distortionary taxes.     

ON FISCAL MULTIPLIERS: ESTIMATES FROM A MEDIUM SCALE DSGE MODEL

This article contributes to the debate on fiscal multipliers, in the context of an estimated dynamic stochastic general equilibrium model, featuring a rich fiscal policy block and a transmission mechanism for government spending shocks. I find the multiplier for government spending to be 1.07, which is largest on impact. The multipliers for labor and capital tax on impact are 0.13 and 0.34, respectively. The effects of tax cuts take time to build and exceed stimulative effects of spending by 12–20 quarters. I carry out counterfactual exercises to show how alternative financing methods and expected monetary policy have consequences for the size of fiscal multipliers.     

So alike,yet so different: Comparing fiscal multipliers across EU members and candidates

We estimate, using a Panel Vector Autoregressive approach and data from 2001Q1 to 2017Q1, the fiscal multipliers of the European Union (EU) members and candidates. These countries are grouped according to their stages of integration: original members, new Eurozone members, and candidates for the Eurozone and the EU itself. For each group, we assess the impact of a positive spending shock (expansionary) or a positive tax shock (contractionary) on GDP. Our findings suggest that: (i) rising government spending increases GDP in both the EU and Eurozone candidates (Keynesian multipliers), but slightly decreases it in the Eurozone members (non-Keynesian multipliers); (ii) higher taxes are associated with mixed results in terms of GDP dynamics - both increases and decreases in terms of GDP are found - in the four country groups (suggesting the presence of Keynesian and non-Keynesian multipliers). Overall, these outcomes indicate that spending multipliers are, compared to tax multipliers, more sensitive to European Union or Eurozone membership.     

Public Preferences for Government Spending Priorities: Survey Evidence from Germany

Employing data from a representative survey conducted in Germany, this paper examines public preferences for the size and composition of government expenditure. We focus on public attitudes towards taxes, public debt incurrence and public spending in six different policy areas. Our findings suggest, first, that individual preferences for the use of additional tax money can be categorised as either capital‐oriented expenditure or public debt reduction. Second, we find that fiscal preferences differ along various dimensions. Specifically, personal economic well‐being, economic literacy, confidence in politicians, political ideology and time preference are significantly related to individual attitudes towards public spending, taxes and debt. The magnitude of the effects is particularly large for time preference, economic knowledge and party preference. Third, public preferences for public spending priorities are only marginally affected when considering a public budget constraint.     

Consumption multipliers of different types of public spending: a structural vector error correction analysis for the UK

The aim of this paper is to investigate the relationship between government spending and private consumption in the UK, for which there is scarce previous empirical evidence. We disaggregate public expenditure into three categories and search for the corresponding private consumption multipliers. Our analysis is based on the estimation of a structural vector error correction model with quarterly non-interpolated data for the period 1981:1–2007:4. Initially, we estimate negative but barely significant effects on consumption of shocks to total public spending. Then, using the public spending breaking down, we find that while shocks to public wages crowd-out private consumption as predicted by neoclassical models, shocks to the non-systematic component of social spending and government purchases of goods and services generate a positive reaction, so to crowd-in private consumption. Thus, the qualitative and quantitative dimensions of fiscal multipliers on private consumption change across different public spending categories. Our findings suggest that any empirical support of competing theoretical models on the issue would benefit from a disaggregation of government expenditure, rather than focusing on the aggregate measure.     

Fiscal Policy and Welfare in a Small Open Economy with Imperfect Competition

This paper considers the effects of fiscal policy in a two-sector small open economy, with unionized labour markets, and heterogeneous types of imperfect competition in the product markets. By making the marginal propensity to import endogenous, the paper shows that there is no robust or general relationship between the balanced-budget multiplier and the degree of imperfect competition. The fiscal multiplier with distortionary taxes can be positive or negative, depending on the size of the importables sector and the foreign firm's market share. The normative rule for fiscal policy depends on the size of the fiscal multiplier. An increase in economic activity is insufficient by itself to induce the government to over-supply public goods relative to the Walrasian case.     

Variation in the effects of government spending shocks with methods of financing: Evidence from the U.S.

Using annual data for the United States, the paper investigates the evidence of variation in the fiscal multiplier with the method of financing government spending. The fiscal multiplier varies in the face of positive and negative shocks and across methods of financing. In general, fiscal expansion appears insignificant on aggregate demand and economic activity. In contrast, the evidence presents a number of significant negative multipliers in the face of fiscal contraction. The combined evidence challenges the effectiveness of fiscal policy and supports arguments to restrain fiscal expansion in an effort to stimulate the economy.     

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.     

Fiscal multipliers in a structural VEC model with mixed normal errors

This paper estimates the effects of fiscal policy shocks on GDP in the United States with a vector error correction (VEC) model in which shocks are identified by exploiting the non-normal distribution of the model residuals. Unlike previous research, the model used here takes into account cointegation between the variables, and applies a data driven method to identify fiscal policy shocks. The approach also allows statistical testing of previous identification strategies, which may help discriminate between them and hence also explain differences between various fiscal multiplier estimates. Our results show that a deficit financed government spending shock has a weak negative effect on output, whereas a tax increase to finance government spending has a positive impact on GDP.     

Automatic stabilizers, fiscal rules and macroeconomic stability

This paper analyzes the effect of the fiscal structure upon the trade-off between inflation and output stabilization induced by technological shocks in a DGE model with nominal and real rigidities that also integrates a rich menu of fiscal variables as well as a target on the debt to output ratio. The channels through which fiscal policy affects macroeconomic stability include supply-side effects of distortionary taxes, the procyclical behavior of public spending induced by fiscal rules and the conventional effect of automatic stabilizers operating through disposable (permanent) income. The paper investigates these channels and concludes that, contrary to what has been found in RBC models, distortionary taxes tend to reduce output volatility relative to lump-sum taxes when significant rigidities are present. We also study the stabilization effect of alternative (distortionary) tax structures and find that these are only relevant if substantial rigidities are present.     

Fiscal multipliers in good times and bad times

This paper estimates the magnitudes of government spending and tax multipliers within a regime-switching framework for the U.S. economy during the period 1949:1–2006:4. Our results show that the magnitudes of spending multipliers are larger during periods of low economic activity, while the magnitudes of tax multipliers are larger during periods of high economic activity. We also show that the magnitudes of fiscal multipliers got smaller for episodes of low growth, while they got larger for episodes of high growth in the post 1980 period. Analyzing the effects of government spending and taxes on consumption and investment spending indicates that the magnitude of the effects of fiscal shocks on consumption and investment is very small.     

Macroeconomic effects of fiscal policy in Pakistan: a disaggregate analysis

This study analyzes the macroeconomic effects of fiscal policy on macroeconomic variables in Pakistan. The study utilizes VAR framework and uses quarterly data of Pakistan from 1976Q1 to 2017Q4. The results showed that after an increase in government expenditures, private consumption and prices take three quarters to increase, while private investment follows the declining trend. Private consumption and interest rate are negatively related with taxes, while private investment and prices are positively related with taxes. Real GDP, private consumption and interest rate respond positively with an increase in developmental expenditure, public consumption and public investment. Private investment is negatively related with development expenditure, public consumption and public investment. An increase in direct tax as well as indirect tax leads to an increase in real GDP, private investment and interest rate, while private consumption takes three to five quarters to responds. Private investment and prices are positively related with non-tax revenue, while real GDP, private consumption and interest rate are negatively related. These results support the Keynesian view that government expenditure and taxes are useful tools to stimulate the economic activity, while crowding-out hypothesis holds in Pakistan as well. An active and efficient role of government is required for macroeconomic stability.     

Persistent government spending and fiscal multipliers: The investment-channel

This paper inspects the mechanism shaping government spending multipliers in various small-scale DSGE setups with endogenous labor supply and capital accumulation. We analytically characterize the short-run investment multiplier, which in equilibrium can be either positive or negative. The investment multiplier increases with the persistence of the exogenous government spending process. The response of investment to government spending shocks strongly affects short-run multipliers on output and consumption.
