我国政府支出和公共投资对私人投资的效应分析

首先采用Diamond模型对公共投资及各项政府支出对私人投资影响进行理论分析;然后利用1980~2005年间的数据,运用协整检验、单方程误差修正模型分析了我国政府支出和公共投资及各项政府支出对私人投资的长短期效应;经验结果表明无论从长期还是短期看政府支出挤出了私人投资而公共投资则挤入了私人投资,国防支出和行政管理支出在长期和短期都挤出了私人投资,社会文教支出长期挤入了私人投资,短期挤出了私人投资。     

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.     

Do government purchases crowd out investment?

The objective of this study is to determine whether federal government purchases negatively impact private investment using times series regression analysis. This study uses quarterly data from the years 1986.1 to 2004.4 in order to provide a relatively contemporary evaluation of the effects of federal purchases on private investment. The empirical results in this study reveal that increases in federal urchases, expressed as a percent of GDP, act to reduce new investment, which provides further support for the theory that government expenditures crowd out private investment.

Effects of government spending on private investment

This paper investigates the effects of military and non-military public expenditures on gross private investment using cointegration and error-correction analysis. The latter type of public spending is disagreggated into expenditures of infrastructure, consumption and other general government expenditures. The empirical evidence from four emerging European countries namely, Greece, Ireland, Portugal and Spain suggests that in some cases public capital spending stimulates investment, while in others it depresses it. Also, the results tentatively indicate that defence spending exerts no influence on private investment, thus adding to the ongoing controversy of the economic effects of military spending.     

Discretionary fiscal policy and economic activity in Greece

This paper investigates the effects of discretionary fiscal policy changes on economic activity and its subcomponents in Greece in the period 2000–2011. Changes in government spending and net taxes have Keynesian effects. An increase in government consumption has the most pronounced positive effects on output growth, private consumption and non-residential investment, while it reduces residential investment. Cuts in the public investment programme crowd in private investment, but are associated negatively with the net exports ratio. Both indirect and direct tax hikes lower private consumption, private investment and output growth. However, higher direct taxes by lowering disposable income they reduce import demand, thus, improving the trade balance.     

Public and Private Investments in Greece: Complementary or Substitute ‘Goods’?

This paper investigates whether government investment spending exerts a positive or a negative effect on private investments. Time-series data for Greece as well as the methodology of cointegration suggest that, over the period 1948-80, public investment spending exerted a positive effect on private investments, while over the period 1981-96, the relationship turned out to be negative. Empirical results indicate that the large increase of the public share in the total investment process tended to crowd out private investments and to jeopardize the growth process of the economy.     

China's Growing Government Debt in a Computable Overlapping Generations Model

This paper simulates the effects of China's growing government debt in a computable equilibrium model of overlapping generations. Our model assumes that the government increases debt to finance its spending in the short run, and then increases taxes or cuts spending to keep the debt–GDP ratio constant. The spending‐driven government debt increases public capital and output in the short run, but decreases private investment, total capital stock, output, and net exports in the long run, and makes the future generations worse off. Among various means of debt control, a decrease in government spending seems to be the least harmful to private investment, capital stock, and output while an increase in capital taxation is most detrimental.     

Do expectations matter? Reassessing the effects of government spending on key macroeconomic variables in Germany

This article contributes to the debate on how to properly identify exogenous fiscal shocks in the data. We include expectations held by consumers and firms into the standard vector autoregression (VAR) framework based on information from historical issues of the German political magazine Der Spiegel. The findings underscore the need to account for expectations, as failing to do so leads to significant misinterpretation of the effects of government spending. When neglecting anticipation effects, our results support the recent findings for Germany by pointing to a rather positive effect of government spending on GDP. However, inclusion of expectations yields a change in this effect, suggesting that government spending is much less beneficial for GDP, as it crowds out private consumption and investment.     

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.     

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).     

关于公共支出与经济增长的国内外研究综述

公共支出与经济增长的关系一直以来为经济学家们所争论。持公共支出促进经济增长观点认为,政府公共支出在经济增长中发挥着重要作用,因为它为经济发展提供了大量的公共品和其他具有外部效应的公共福利或服务,从而鼓励和便利了私人投资,形成了一个较好的投资环境,促进了经济增长。而持反对意见的认为,公共支出往往是生产率较低的,为融通政府支出而形成的高税收又会对私人部门的消费和投资造成很大的负面影响,因此,必须缩减政府支出,才能保证经济增长。当然也有人持两者根本就没有关系的观点。     

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。     

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.     

Asymmetric output growth effects of government spending: Cross-sectional and panel data evidence

Using a model that accommodates asymmetric adjustments of output growth to changes in growth of government spending, the effects of aggregate and disaggregate government spending variables on output growth are examined. Both cross-section and panel regression estimations are conducted. Robustness of results to joint-endogeneity of output and government spending, alternative conditioning variables, and cointegration is investigated. Aggregate government spending appears to have positive output growth effects particularly in periods of below-trend growth in this variable. The government sector's productivity appears to be higher than non-government sector's productivity when spending growth is below-trend growth and only for non-OECD countries; no differences in sectoral productivities are detected for OECD countries. Government consumption spending has no significant output growth effects, but government investment spending has positive output growth effects particularly when its growth falls below its trend-growth; this favorable effect turns negative when government investment spending growth exceeds its trend-growth. Results are robust across alternative model specifications and estimation methods.     

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.     

Public capital formation and labor productivity growth in Chile

Following the lead of the endogenous growth literature, this article analyzes the impact on labor productivity growth of public and private investment spending in Chile. Using cointegration analysis, the results of the dynamic labor productivity function for the 1960–95 period show that (lagged) public and private investment spending, as well as the rate of growth in exports, has a positive and highly significant effect on the rate of labor productivity growth. The estimates also indicate that increases in government consumption spending have a negative effect on the rate of labor productivity growth, thus suggesting that the composition of government spending may also play an important role in determining the rate of labor productivity growth. The findings call into question the politically expedient policy in many Latin American countries of disproportionately reducing public capital expenditures to meet targeted reductions in the fiscal deficit as a proportion of GDP.     

Government size,composition of public spending and economic growth in Brazil

The performance of the fiscal policy is largely affected by the relationship between government size, composition of public spending and economic growth. We use a theoretical framework to find optimal relations among these variables and confront them with a panel data for the Brazilian states. Private capital and government spending are substitute inputs in production as the Brazilian states require provision of public spending to fill gaps in the underdeveloped private sector. Public investment and current government expenditures are combined in fixed ratios in the overall government spending due to strong rigidity of the public budget. The optimal share of public investment is considerably lower than current expenditures, as occurs in developing countries characterized by low economic dynamism. Finally, the average tax burden from the data is below the estimated optimal level, meaning that there is space for increasing tax rate without harming economic growth for some Brazilian states.     

Fiscal policy, long‐run growth, and welfare in a stock‐flow model of public goods

Abstract.  We introduce public capital and public services as inputs in an endogenous growth model. We show that the growth rate depends on the apportionment of tax revenues between the accumulation of public capital and the provision of public services. When public spending is financed by proportional income taxes, the growth rate, the level of public spending as a proportion of GDP, the level of investment in public capital as a proportion of total public spending, and the level of private investment as a proportion of total private spending all are lower in the equilibrium outcome than in the optimal outcome.

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.     

Macroeconomic effects of government spending in China

Government spending plays an important role in determining economic performances in China. Its macroeconomic effects are analysed in this paper. We show that government spending in China Granger‐causes output, consumption and investment booms as well as inflation, and has a multiplier larger than 1. The large multiplier effects are found not only in aggregated time‐series data but also in panel data at the provincial level. We also provide a theoretical model and Monte Carlo analysis to rationalize our empirical findings. Our theoretical and Monte Carlo analyses support the large multiplier found in China but also suggest that government spending is not necessarily a free lunch in spite of the large multiplier effects.
