Financing government investment and its implications for public capital: A small open economy perspective

Expenditure reductions played a key role in many small open economies during fiscal consolidation, with large declines in public investment. This led to a reduction in public capital stock and affected the competitiveness of these economies. After the sovereign debt crisis, the governments that consider increasing investment to replenish the public capital stock have limited fiscal space and have to avoid external imbalances. We show that using budget-neutral investment spending can generate long-term benefits of higher public capital stock while at the same time limiting negative consequences for the public finances and the trade balance. The best way of financing government investment, which preserves fiscal and trade balances, and increases welfare, is by reducing other government spending. The second-best is financing investment with value-added tax. Financing with debt worsens fiscal and trade balances, while using distortionary labour taxes reduces labour supply, increases wage costs and worsens the trade deficit in the short run.     

国债规模的均衡数量及优化

笔者基于世代交叠模型,假定政府执行赤字预算体制,在市场结清的均衡状态下得到了确定国债规模与私人资本规模之比值的解析式。通过模拟发现税率、基本财政支出率、产出关于私人资本的弹性等是决定该比值大小的主要因素。     

TAX DISCOUNTING VS. CROWDING OUT

The “crowding out” effect of debt-financed government spending on the private sector consumption-saving decision and on private investment behavior has been a controversial subject for several years. Do increases in debt-financed government spending stimulate private consumption and saving in the short run, as well as private consumption in subsequent periods? Or does the realization that future taxes must be raised to finance repayment of the debt result in a lack of stimulus for consumption as well as no detrimental impact on subsequent private saving? This article empirically tests for the presence and/or magnitude of tax discounting and crowding out, carefully distinguishing between the two, and decomposes government debt instruments according to their maturities in order to determine impact due to a reorientation of debt structure. The results do not support the existence of tax discounting, suggesting instead that government deficits do stimulate current consumption.     

公共资本投资、内生经济增长与合理政府债务规模*

本文基于一个具有内生增长机制的三部门世代交叠模型,讨论了政府举债为公共投资进行融资时经济的长期均衡;同时,通过数值模拟方法考察了我国的均衡政府债务规模及其影响因素。结果表明：在特定条件下,经济系统存在一个正的均衡政府债务-产出比重,该债务比重水平明显受到公共投资—产出比重、公共投资的债务融资比重、民间资本产出弹性等参数的影响。但是,均衡政府债务比重并不是无限上升的,当上述参数超过特定临界值时,经济系统无法达到均衡,政府债务-产出之比将持续上升,财政将不可持续。另外,当民间资本产出弹性较低时,较高的均衡政府债务比重可能导致经济运行动态无效率。数值模拟结果还显示,基于不同的假设情形,我国的均衡政府债务-产出比重均在不同程度上高于当前实际的政府债务规模,这为我国在未来期间实施扩张性财政政策提供了有利的依据。     

Public Investment and Economic Growth in Latin America: an Empirical Test

The paper analyzes the impact on economic growth of public investment spending and other relevant variables (such as human capital) for nine major Latin American nations over the 1983–93 period. The results suggest that both public and private investment spending contribute to economic growth. Overall central government consumption expenditures, on the other hand, are found to have a negative effect on private investment and growth. Finally, public expenditures on education and healthcare are found to have a positive and statistically significant effect on private capital formation and long–term economic growth. From a policy standpoint, the results suggest that indiscriminate cuts in public and private investment spending are likely to be counterproductive in the long run, and more importantly, scarce public expenditures should be channeled to the promotion of new human capital (via primary and secondary education) and the maintenance of existing human capital (through healthcare expenditures).     

Government expenditure composition and fiscal policy spillovers in small open economies within a monetary union

We examine the implications of government expenditure that is complementary to private consumption, and government investment that can improve the productivity of private capital, in a global DSGE model. We show that government investment can improve an economy’s external competitiveness and stimulate private investment. If governments can finance this investment by reducing consumption that is not complementary to private consumption, then this is ex-ante budget-neutral, provides a small, but persistent stimulus without a deterioration in competitiveness, and leads to lower debt in the medium run. We also examine the cross-border transmission channels of government expenditure shocks in a monetary union when government consumption is complementary to private and public investment is productive. While both assumptions enhance cross-border spillovers, a direct import content is required to generate spillovers similar to those found in the empirical literature.     

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.     

Sudden stops in a currency union – some lessons from the euro area

During the Great Financial Crisis several euro area Member States with current account deficits were subject to sharp reversals of private capital flows. We examine how the specific policy rules of the euro area's payments system TARGET2 affects the macroeconomic adjustments to sudden stops. We find that – in the short run – public capital flows in form of TARGET2 help euro area‐deficit countries to stabilize output, consumption, and investment after a sudden stop of private capital inflows. In the long run, however, euro area countries suffer under a prolonged economic recovery and accumulated large public debt as well as higher welfare losses relative to euro peggers.     

Assessing fiscal episodes

In an OCDE panel, for the period 1970–2010, we assess the effects of fiscal consolidation episodes, with four different definitions. Our results reveal that lower final government consumption increases private consumption in three out of the four approaches, when a fiscal consolidation occurs, and the debt ratio is above the cross-country average. The magnitude of these coefficients is higher for countries with lower debt levels, implying more successful consolidations associated with reduced crowding-out effects. There is some evidence of non-Keynesian effects for both private consumption and private investment, and the effects of social transfers on private investment tend to be negative, both in the short and long run. In a financial crisis, such effects are also more prone to happen. Finally, raising long-term interest rates reduces per capita private investment.     

Optimal fiscal policy in the neoclassical growth model revisited

This paper studies optimal taxation in a version of the neoclassical growth model in which investment becomes productive within the period, thereby making the supply of capital elastic in the short run. Because taxing capital is distortionary in the short run, the government׳s ability/desire to raise revenues through capital income taxation in the initial period or when the economy is hit with a bad shock is greatly curtailed. Our timing assumption also leads to a tractable Ramsey problem without state-contingent debt, which can give rise to debt-financed budget deficits during recessions.     

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.     

Sustainable government debt in a two-good,two-country overlapping generations model

The recent dramatic rise of government deficits in most advanced countries to counter the effects of the global financial crisis arouses renewed interest for one of the perennial topics of fiscal policy: the sustainability of government debt. This paper explores maximum sustainabile debt in a two-good, two-country overlapping generations (OLG) model and analyzes existence and dynamic stability of steady states as well as the transitional dynamics of private capital when government debt remains below the maximum sustainable level. We find that maximum government debt levels for both countries exist and are negatively related. Moreover, if sustainable government debt is unilaterally expanded, private capital is crowded out in both countries while the terms of trade of the debt-expanding country are unaffected if capital income shares are internationally equal.     

Disaggregated approach to government spending shocks: a theoretical analysis

We calibrate a dynamic stochastic general equilibrium model that features a transmission mechanism with different types of government spending, while the literature usually treats government spending as a homogenous compound. In this regard, we manage to distinguish between different types of government spending (namely: government investment, government wage component consumption and non-wage component consumption) where each type of spending has a varied role in the economy. The government wage increase has the largest positive effect both on private consumption and output by affecting the economy through the government production. This is a natural consequence of government production being complementary to private consumption in our model. Other two government spending types, namely government non-wage consumption and government investment, also have positive effects on output, whereas their responses on (private) consumption are mostly negative. These results provide an alternative explanation for the wide range of multipliers existing in the literature as our setup enables them to produce different effects on macroeconomic variables.     

财政政策、货币政策与国外经济援助

本文通过把国外经济援助分成直接对私人的经济援助和直接对政府的经济援助来讨论这两类经济援助对政府财政政策和货币政策的影响。我们发现对私人的经济援助的增加可以使得私人消费水平和政府公共消费水平增加 ,但是它也导致政府收入税税率和通货膨胀率的提高 ;另一方面 ,对政府的经济援助增加可以使得均衡时的私人资本存量、私人消费水平和政府公共消费水平增加 ,同时可以使得均衡时的收入税税率和通货膨胀率下降。     

Welfare Analysis of a Fiscal Reconstruction Policy in an Overlapping Generations Economy with Public Investment

Constructing an endogenously growing overlapping generations model with public investment, we examine the welfare effects of a fiscal reconstruction policy. In this paper we define a fiscal reconstruction policy as a policy where the government reduces its spending level without changing the tax revenue and allocates the surplus of the revenue to redeem public debt. We show that if government spending is not productive it is possible that a fiscal reconstruction policy improves the utilities of both the current and future generations, while if government spending is productive it can harm the utilities of both generations.

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。     

Investment Cycles and Sovereign Debt Overhang

We characterize optimal taxation of foreign capital and optimal sovereign debt policy in a small open economy where the government cannot commit to policy, seeks to insure a risk-averse domestic constituency, and is more impatient than the market. Optimal policy generates long-run cycles in both sovereign debt and foreign direct investment in an environment in which the first best capital stock is a constant. The expected tax on capital endogenously varies with the state of the economy, and investment is distorted by more in recessions than in booms, amplifying the effect of shocks. The government's lack of commitment induces a negative correlation between investment and the stock of government debt, a "debt overhang" effect. Debt relief is never Pareto improving and cannot affect the long-run level of investment. Furthermore, restricting the government to a balanced budget can eliminate the cyclical distortion of investment.     

Human capital formation,learning by doing and the government in the process of economic growth

We present an endogenous growth model with human capital and learning by doing. Human capital is not an input factor in the production process of final output but it affects the ability to build up knowledge capital as a by‐product of cumulated investment (learning by doing). Human capital is formed in the schooling sector that is financed by the government. The government may run into debt but obeys the inter‐temporal budget constraint. The article analyzes the structure of the model and studies the effects of different budgetary policies as regards the balanced growth rate, transition dynamics and with respect to welfare.     

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.     

PUBLIC AND PRIVATE INVESTMENT AND ECONOMIC GROWTH IN MEXICO

This paper analyzes the impact on economic growth of public and private investment spending in Mexico. Public investment expenditures had a positive and significant effect on output growth. Public investment's impact on economic growth was statistically identical to the impact of private capital spending. The contribution of public investment to output expansion came at the expense of private investment as indicating a significant crowding out effect.
