The impact of debt finance on aggregate demand

The crowding-out hypothesis has received extensive theoretical treatment but little supporting empirical examination. This paper presents the results of several empirical tests of the crowding-out hypothesis. These tests examine the impact of debt finance on aggregate demand, employment, inflation, and the unemployment rate. The results indicate that debt-financed fiscal initiatives crowd out a substantial amount of private spending, but do have a net expansionary effect on economic activity.     

李嘉图等价定理及其在中国的适用性分析

李嘉图等价定理认为,政府的财政收入形式的选择,不会引起人们经济行为的调整。但是,现代经济学家们并非完全同意李嘉图的见解,无论是对其必要条件的检验还是对其结论的检验都存在着争论。而通过实证分析我国1989—2004年的政府发债分别与消费和投资的关系,可以得出结论：从历史数据来看,李嘉图等价定理在我国并不适用。     

GOVERNMENT CONSUMPTION AND THE COMPOSITION OF PRIVATE EXPENDITURE: A CONDITIONAL ERROR CORRECTION MODEL

In this paper we provide empirical evidence of the relationship between government purchases and private expenditure by adopting a microeconomic approach. Using UK quarterly data, a long‐run demand system conditioned to the public sector is obtained by specifying a vector error correction model in which government consumption is assumed as an exogenous I(1) forcing variable. Our findings reject the hypothesis of separability of individual preferences between public and private expenditures, with simultaneous crowding‐out/in effects. Moreover, crowding‐out effects of government consumption on private spending are found to be larger for those goods and services that produce similar utility.     

Debt financing of public investment: On a popular misinterpretation of “the golden rule of public sector borrowing”

In this paper I challenge the proposition that the golden rule of public sector borrowing is consistent with the principle of intertemporal allocative efficiency, in the sense that growth-enhancing public investment justifies a structural public deficit. I demonstrate that in the long run the social opportunity cost of debt-financed public investment exceeds the social opportunity cost of tax financed public investments. This result holds if the social rate of time preference is lower than the interest rate on government borrowing. Thus a benevolent government would use taxes to finance public investment. In the short run, debt financing is justified if public investment has a considerable growth effect on private consumption. This requires a corresponding initial undersupply of public capital.     

Aggressive oil extraction and precautionary saving: Coping with volatility

The effects of stochastic oil demand on optimal oil extraction paths and tax, spending and government debt policies are analyzed when the oil demand schedule is linear and preferences quadratic. Without prudence, optimal oil extraction is governed by the Hotelling rule and optimal budgetary policies by the tax and consumption smoothing principle. Volatile oil demand brings forward oil extraction and induces a bigger government surplus. With prudence, the government depletes oil reserves even more aggressively and engages in additional precautionary saving financed by postponing spending and bringing taxes forward, especially if it has substantial monopoly power on the oil market, gives high priority to the public spending target, is very prudent, and future oil demand has high variance. Uncertain economic prospects induce even higher precautionary saving and, if non-oil revenue shocks and oil revenue shocks are positively correlated, even more aggressive oil extraction. In contrast, prudent governments deliberately underestimate oil reserves which induce less aggressive oil depletion and less government saving, but less so if uncertainty about reserves and oil demand are positively correlated.     

内生增长、政府生产性支出与中国居民消费

中国财政支出的较大一部分用于生产建设,中国居民消费与政府生产性支出表现出稳健的正相关关系,这一事实与从标准的新古典和新凯恩斯模型得出的挤出效应截然不同。本文构建了包含存量和流量两部分政府生产性支出的内生增长模型,研究表明,政府支出增加在提高税负、挤出居民消费的同时,也通过其生产性增加收入、挤入居民消费;政府支出增加究竟挤入还是挤出居民消费取决于两种效应的比较以及政府的生产性支出比重和税负水平。政府生产性支出的最优结构等于其相对生产性之比,政府支出的最优规模等于政府支出的生产性。     

Ricardian equivalence and fiscal distortions in the Dominican Republic

This paper tests the Ricardian equivalence hypothesis in the context of the Dominican Republic (DR). The results rejected the Ricardian theorem but a weaker version is shown to have significant implications for the DR. If the government borrows to increase spending, private consumption is crowded out and the economy will suffer in the long run. The outcome is worst if the government borrows to deliver a tax cut. In particular, for every RD$ 1.00 of additional debt incurred to finance government primary spending, private consumption and gross domestic product (GDP) fall by a meaningful RD$ 2.15 and RD$ 1.15 respectively. If the debt is used to finance the tax cut, the fall is RD$ 2.15 in both consumption and output. Interestingly, if the government uses taxes to cover a budget deficit, the effect is neutral and consistent with Ricardian equivalence. The paper argues that fiscal distortions are in part responsible for these multipliers. Distortions are estimated to be 21 % coming from different sources including taxes evasion and fiscal drainage. These findings suggest that the DR could benefit from either reducing the level of fiscal distortions or the size and scope of the Dominican government. If, however, the government continues to pursue an active fiscal role under the current environment, it will generate an unnecessary burden to consumption and economic growth.     

Public debt in a basic endogenous growth model

We work out the mechanism that makes public debt affect the allocation of resources in the long-run. To do so we analyze an AK growth model with elastic labor supply and a government sector. The government levies a distortionary income tax and issues bonds to finance lump-sum transfers and non-distortionary public spending. We show that the long-run growth rate is the smaller the higher the debt ratio if the government adjusts public spending to fulfill its inter-temporal budget constraint. If the government adjusts lump-sum transfers the public debt ratio does not affect the balanced growth rate.     

The effects of fiscal policy on economic activity in Finland

This study analyzes whether fiscal policy decisions have real effects on the economy of Finland, and if they do, what are the strength and durations of the effects. We utilise the Vector Stochastic Process with Dummy Variables (VSPD) method in our empirical work. This approach is a suitable tool to study event-based episodes. Fiscal policy shocks do have an effect on the economic activity of Finland when the time period 1990–2007 is investigated. A positive tax shock (or a policy that increases public sector revenues) seems to have a positive effect on Investment and GDP but the response of private consumption is mixed. Results clearly indicate that increase in Government spending crowds out private sector activity, and the effect takes place sooner than with the Revenue variable in question. This is a clear evidence for the crowding out effect.     

An intertemporal general equilibrium analysis of financial crowding out: A policy model and an application to Australia

This paper constructs a two-period, perfect foresight general equilibrium model that analyzes crowding out. Private investment is debt financed, while government deficits are financed by money and debt. The existence of equilibrium is demonstrated and the model is applied to Australia for 1981–1982, the last years for which Australia had a fixed exchange rate. A benchmark solution is derived and two counterfactual simulations are carried out. Small increases in real government spending are found not to lead to crowding out, while an increase in the debt financed portion of the government's budget deficit does lead to crowding out.     

The macroeconomic effects of fiscal policy in Portugal: a Bayesian SVAR analysis

With a new quarterly dataset we estimate a Bayesian Structural Autoregression model and a Fully Simultaneous System approach to analyze the macroeconomic effects of fiscal policy. Results show that positive government spending shocks, in general, have a negative effect on real GDP; lead to “crowding-out” effects of private consumption and investment; have a persistent and positive effect on the price level and a mixed impact on the average financing cost of government debt. Explicitly considering the government debt dynamics in the model is also important. A VAR counter-factual exercise confirms that unexpected positive spending shocks create relevant “crowding-out” effects.     

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.     

The government spending and private consumption: a panel cointegration analysis

In this article, whether an increase in government spending will crowd out the private consumption is re-examined. This article augments the empirical literature by extending this issue to panel data. The empirical framework applies the panel cointegration model, dynamic OLS (DOLS), proposed by Kao and Chiang [On the estimation and inference of a cointegrated regression in panel data. Working Paper, Economics Department, Syracuse University, 1999.]. Evidence from 24 OECD countries indicates a significant degree of substitutability between government spending and private consumption when the real disposable income is included, which rejects the permanent income hypothesis. The existence of crowding out renders the Keynesian plea for expansionary fiscal policy unconvincing.     

Should We Worry about Government Debt? Thoughts on Australia's COVID-19 Response

No. While the COVID-19 crisis has required a dramatic increase in debt-financed government spending, in the current conditions the benefits from this debt are unusually high and the costs unusually low. While conditions can change, the Australian Government can right now hedge against these risks by lengthening the maturity structure of government debt, even at the cost of a modest increase in its current servicing costs.     

The optimal treatment of tax expenditures

This paper analyzes the optimal treatment of tax expenditures. It develops an optimal tax model where individuals derive utility from spending on a “contribution” good such as charitable giving. The contribution good has also a public good effect on all individuals in the economy. The government imposes linear taxes on earnings and on the contribution good so as to maximize welfare. The government may also finance directly the contribution good out of tax revenue. Optimal tax and subsidy rates on earnings and the contribution good are expressed in terms of empirically estimable parameters and the redistributive tastes of the government. The optimal subsidy on the contribution good is increasing in the size of the price elasticity of contributions, the size of the crowding out effect of public contributions on private contributions, and the size of the public good effect of the contribution good. Numerical simulations show that the optimal subsidy on contributions is fairly sensitive to the size of these parameters but that, in most cases, it should be lower than the earnings tax rate.

The effect of inflation uncertainty on ‘crowding out’

It is widely recognized that expansionary fiscal policy can crowd out private investment. The degree of crowding out depends in part on the degree of substitutability between public and private securities. In this paper, we look at how inflation uncertainty affects this substitutability and the degree of crowding out. Depending on the covariance of the return of private securities with the rate of inflation, the degree of substitutability, and thus the level of crowding out, will diminish as inflation uncertainty increases. Indeed, an increase in government debt may actually decrease the real return required on private securities, leading to “negative” crowding out.     

政府支出对居民消费的影响——对Barro-Ricardo等价之谜的中国经验分析

本文基于居民消费跨期最优化分析框架,从理论及实证角度分析了政府支出对居民消费的影响。理论研究表明,政府支出对居民消费的影响主要取决于消费者相对风险规避系数及私人消费支出与政府支出之间的相关系数。并以中国为例,在李嘉图等价框架下从经验角度考察了中国政府支出对居民消费的影响。短期内,李嘉图等价不成立,政府支出与居民消费呈互补关系,即政府支出增加将导致居民消费增加。尤其需要注意的是,与通过征税来增加政府支出相比,通过发行国债增加政府支出对总需求的扩张效应更大,积极的财政政策在我国是有效的。但在长期中,政府支出将完全挤占居民消费支出,因而支出政策不宜用于实现政府的长期经济目标。     

Intergenerational conflict and public sector size and structure: A rationale for debt limits?

How do budget rules influence the size and structure of the public sector? This question is considered in an overlapping generations political economy model. The different horizons of agents influence their voting behaviour and lead to excessive deficit financing and debt accumulation, reducing welfare of all subsequent generations. Along an equilibrium trajectory with increasing debt, the tax burden increases and public sector activities are crowded out due to the increasing costs of debt servicing. A debt ceiling may halt this process leading to less debt, more public consumption and higher welfare.     

Fiscal policy reforms in general equilibrium: The case of Greece

This paper quantifies the macroeconomic and welfare implications of (i) changes in the tax-spending mix and (ii) debt consolidation policies. The setup is a neoclassical growth model augmented with a relatively rich public sector. The model is calibrated to the Greek economy. The results suggest that, if the goal of fiscal policy is to stimulate the economy and increase welfare by changing the tax mix, then it should decrease the tax rate on labour income and increase the consumption tax rate. While higher public investment spending is good for the economy, it is lower public consumption spending that is found to be expansionary. The results also suggest that both tax- and expenditure-based debt consolidation policies lead to worse economic activity in the short run, but they have strong beneficial effects in the medium and long run when the consolidation period finishes.
