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.     

Government Spending, Taxation, and Oil Revenues in Mexico

The paper analyzes the intertemporal relationship between oil duties, taxes, government spending, and GDP in Mexico during the 1981–98 period. The results from estimating a VAR model, impulse response functions, and variance decompositions on the quarterly series of taxes, government spending, oil duties, and GDP suggest that there seems to be a substitution effect between oil duties and tax revenues, and that tax revenues are not able to absorb temporary decreases in oil duties. Also, increases in tax revenue might lead to increasing government spending, but short–run increases in government spending are not likely to lead to political pressure to reduce the expected budget deficit via increased taxation and/or oil revenues. Lastly, GDP is not stimulated in the short–run by temporary increases in government spending and, thus, stabilization measures adopted in recent years to reduce the size of the government are not likely to significantly undermine GDP growth.     

Integrated water and economic modelling of the impacts of water market instruments on the South African economy

A static computable general equilibrium model of South Africa is adapted to compare new taxes on water demand by two industries, namely forestry, and irrigated field crops. Comparisons are made with respect to both the short and the long run, in terms of three target variables, namely (i) the environment; (ii) the economy; and (iii) equity. Since the taxes on the two industries do not raise the same amount of revenue, the target variables are calculated per unit of real government revenue raised by the new taxes (also referred to as the marginal excess burdens of the taxes). The model results are robust for moderate values of the water elasticity of demand in the two industries, in both the long and the short run. The tax on irrigated field crops performs better in terms of all three the target variables in the short run. In the long run the tax on irrigated filed crops is better in terms of water saving, but reduces real GDP and the consumption by poor households.     

Fiscal policy and economic activity in South Asia

This paper analyzes whether fiscal policy in South Asia amplifies or smoothens business cycle fluctuations. It estimates several econometric models to explore the cyclicality of government spending and tax buoyancy. In South Asia, tax revenue increases less than one to one with changes in gross domestic product (GDP), but public spending increases more than proportionally. For each percentage point change in GDP growth, government expenditure changes by 1.3 percentage points. While changes in tax revenue have no significant impact on economic activity, the government spending multiplier is positive and significant: each additional US dollar (USD) of spending leads to an immediate increase in GDP of 0.2 USD and to an increase of 0.4 USD in the medium run. The impact of public spending on economic activity is entirely due to capital expenditure, which is also more procyclical. Procyclical public spending and a positive expenditure multiplier imply that fiscal policy in South Asia amplifies boom‐and‐bust cycles. These results are in line with those of other emerging markets and developing economies and robust to different model specifications and estimation strategies.     

EU fiscal stance vulnerability: Are the old members the gold members?

This paper investigates the effect of aggregate shocks on the fiscal stance of the EU, and of its old (OMS) and new (NMS) member states over a business cycle. The fiscal stance is measured by the government deficit. To study the impact of aggregate shocks, we use impulse responses derived from a pooled structural vector autoregression model estimated on annual panel data. We find that the fiscal deficits of OMS could be vulnerable to discretionary changes in government expenditures and revenues. In contrast, the fiscal stance of NMS shows vulnerability to GDP shocks, because the increase in revenues after a positive GDP shock is often outpaced by greater expenditure increases in NMS. The estimated fiscal vulnerabilities stem from disproportionate policy responses concerning government expenditures and a lacking discipline to control pro-cyclical fiscal spending. Our findings for the EU thus support application of fiscal rules focused on government expenditure rather than other fiscal variables.     

Foreign direct investment and growth in India: a cointegration approach

The two-way link between foreign direct investment and growth for India is explored using a structural cointegration model with vector error correction mechanism. The existence of two cointegrating vectors between GDP, FDI, the unit labour cost and the share of import duty in tax revenue is found, which captures the long run relationship between FDI and GDP. A parsimonious vector error correction model (VECM) is then estimated to find the short run dynamics of FDI and growth. Our VECM model reveals three important features: (a) GDP in India is not Granger caused by FDI; the causality runs more from GDP to FDI; (b) trade liberalization policy of the Indian government had some positive short run impact on the FDI flow; and (c) FDI tends to lower the unit labour cost suggesting that FDI in India is labour displacing.     

Effect of the Tax System ON R&D Intensity,Growth, Wages and Consumption Share

We propose a general equilibrium knowledge‐driven (semi‐)endogenous‐growth model with horizontal R&D, which is extended to consider two types of labour, skilled and unskilled, and exogenous government expenditure, financed through taxes on financial assets and on labour income, to analyse the implications of the tax system on R&D intensity, economic growth, wage inequality and consumption share in the output. In particular, we show that: (i) taxes have negative influence in the consumption share, being higher the marginal effect of the labour‐income tax; (ii) for any given government expenditure share, an increase (a decrease) in financial‐assets tax decreases (increases) the labour‐income tax; (iii) only the financial‐assets tax affects negatively the R&D intensity and the skill‐premium; thus, to reduce the skill‐premium the financial‐assets tax must increase; (iv) ignoring the effect on wage inequality and on R&D intensity, taxes are substitutes.     

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.     

Shifting Taxes from Labor to Consumption: More Employment and more Inequality?

This paper investigates the effect of shifting taxes from labor income to consumption on labor supply and the distribution of income in Germany. We simulate stepwise increases in the value‐added tax (VAT) rate, which are compensated by revenue‐neutral reductions in income‐related taxes. We differentiate between the personal income tax (PIT) and social security contributions (SSC). Based on a dual data base and a microsimulation model of household labor supply behavior, we find a regressive impact of such a tax shift in the short run. When accounting for labor supply adjustments, the adverse distributional impact persists for PIT reductions, while the overall effects on inequality and progressivity become lower when payroll taxes are reduced. This is partly due to increases in aggregate labor supply, resulting from higher work incentives.     

Cyclical Multiplier and Zero Low Bound Effects of Government Expenditure on Economic Growth: Evidence for Greece

This study explores the impact of government expenditure multipliers on economic growth utilising an Autoregressive Distributed Lag (ARDL) approach. We provide evidence on the short‐term dynamics as well as the long‐run expenditure multiplier effects on economic growth for the Greek economy over the period 1960–2014. We find that the size of the multiplier does not differ substantially over the phases of the business cycle. Our results also indicate that irrespective of the scale of inflation, government expenditure positively affects economic growth, whilst inconclusive evidence is obtained in the case of exceptionally low interest rates.     

Taxation, Bequests, and Short and Long Run Timber Supplies: An Overlapping Generations Problem

This paper uses an overlapping generations model with one-sided altruism to study the effects of several forest taxes that target bequests and affect timber supply. Unlike previous work, we investigate bequests and timber supply in both the short and long run when bequests are costly (e.g., taxed). The landowner's problem is examined in the short run, while the government's problem is examined in the long run assuming the existence of a steady state. We also consider taxes targeting harvests, growth, savings and bequests. Several new results are established concerning the interactions of taxes that might be used by a government to alter short and long run forest capital stocks: (i) the presence of a forest bequest tax affects the neutrality of harvest tax in both the short and long run, (ii) in the long run the bequest tax decreases bequests and timber supplies. When the bequest tax is not present, the capital income tax is neutral with respect to bequest and timber supply, while the harvest tax is neutral only if forest productivity is also not taxed. Finally, (iii) in the short run, the substitution and total effects of taxes in landowner decisions generally depend on the presence of the bequest tax. The results have implications for Pigouvian tax design and second best tax choice.     

我国的政府教育支出与经济增长——基于1980—2011年的数据分析

对于政府教育支出与经济增长的关系实证研究并没有确定的结论。本文利用我国1980-2011年的时间序列数据分析了政府教育支出对经济增长的影响。实证研究表明,无论是在长期还是短期内政府教育支出都对经济增长具有正的显著的影响,即我国的政府教育支出能够促进经济增长。 Granger因果检验表明,我国的政府教育支出与经济增长之间存在双向因果关系。另外,长期中政府教育支出对经济增长的影响效果大于短期。这说明政府教育支出对经济增长的影响是个长期的累积过程,因而教育投入不应该是一种短期行为。目前我国政府的教育支出仍处于相对较低的水平,具有较大的提升空间,从而具有推动经济增长的巨大潜力。因此,为保持经济的持续增长,在近期和长期内不断加大政府对教育的投入、优化教育资源的配置应是一项极其重要的教育政策。     

How much to share: Welfare effects of fiscal transfers

Recent sovereign debt crisis has challenged policy makers to explore the possibility of establishing a fiscal transfer system that could alleviate the negative impact of asymmetric shocks across countries. Using a simple labour production economy, we first derive an analytically tractable solution for optimal degree of fiscal transfers. In this economy, fiscal transfers can improve welfare by moving the competitive equilibrium with fiscal transfers closer to the social planner's solution. We then extend the model to a DSGE setting with capital, international bond and linear taxes, and we analyze how implementation of a simple revenue sharing rule affects welfare and macroeconomic variables over time. Simulation results show that risk sharing through fiscal transfers always improves welfare in the long run. However, under certain model specifications, short‐run transitional welfare loss can outweigh the long‐run benefits. These results suggest that, in designing fiscal transfers across countries, government should take into consideration the intertemporal nature of welfare gains.     

中国共享式经济增长实证研究——基于公共支出、部门效应和政府治理的分析

文章首先基于多维贫困指标SHPI构建了共享式增长指数PEG,然后运用公共支出、政府治理水平和部门效应三个方面的指标来考察共享式增长。文章具体通过协整和误差修正模型分析了长期和短期影响共享式增长的主要因素及其调整机制,并在此基础上重点估计了各部门公共支出对共享式增长的影响。文章发现1978-2008年中国经济增长总体上具有共享性,但是大部分年份的共享程度较低。长期内,在公共支出、部门效应和政府治理水平三大类因素中公共支出方面的三个变量对PEG的影响最大。短期内,政府一般性支出和政府规模对共享式增长程度有非常显著的消极影响。     

TAXES, GROWTH AND THE CURRENT ACCOUNT TICK-CURVE EFFECT

This paper examines the dynamic and long run effects of a shift from income taxes to consumption taxes in a growing small open economy. We introduce a government sector that maintains a balanced budget and expenditure at a constant proportion of domestic income to a small open economy Swan-Solow model. Our framework provides a previously unidentified dynamic effect that is robust to endogenising the savings rate. Lowering the income tax rate promotes economic growth and has a tick-curve effect on the current account balance, characterised by instantaneous deterioration, a period of recovery and gradual convergence to an improved position in the long run.     

Endogenous Growth,Taxes and Government Spending: Theory and Evidence*

This paper provides a theoretical and empirical investigation of the simultaneous effects of taxes and government spending on long‐run economic growth in an endogenous growth framework. A two‐sector model is considered: one sector produces physical output and the other produces human capital. Government expenditure is divided into several categories, and several types of taxes are included. The property tax is especially interesting because it is a major source of revenue for local government. The theoretical model is estimated using annual panel data from North Carolina counties. This study finds that state‐level fiscal policies affect economic growth but county‐level fiscal policies do not.     

An Empirical Analysis of the Determinants of Foreign Aid: A Panel Approach

This paper uses a panel approach to examine the determinants of foreign aid. It examines the extent to which taxes on international trade and the scope of government activities, ethnicity, private credit, and education determine foreign aid. The paper specifies and estimates a model that explains the allocation of foreign aid among 151 countries over the period 1975 to 1998. The key empirical finding suggests that Taxes on Trade increases foreign aid dependency. Moreover, trade, private credit, foreign direct investment, GDP per worker, and government consumption are important determinants of foreign aid. The factors that appear to decrease foreign aid include: Years of schooling, private credit, trade, and GDP per worker. The factors that appear to increase foreign aid include: Taxes on international trade, ethnicity, and government consumption.     

WHAT IT TAKES TO SOLVE THE U.S. GOVERNMENT DEFICIT PROBLEM

This paper uses a structural multi‐country macroeconometric model to estimate the size of the decrease in transfer payments (or tax expenditures) needed to stabilize the U.S. government debt/gross domestic product (GDP) ratio. It takes into account endogenous effects of changes in fiscal policy on the economy and in turn the effect of changes in the economy on the deficit. A base run is first obtained for the 2013:1–2022:4 period in which there are no major changes in U.S. fiscal policy. This results in an ever increasing debt/GDP ratio. Then transfer payments are decreased by an amount sufficient to stabilize the long‐run debt/GDP ratio. The results show that transfer payments need to be decreased by 2% of GDP from the base run, which over the 10 years is $3.2 trillion in 2005 dollars and $4.8 trillion in current dollars. The real output loss is 1.1% of baseline GDP. Monetary policy helps keep the loss down, but it is not powerful enough in the model to eliminate all of the loss. The estimates are robust to a base run with less inflation and to one with less expansion. (JEL E17)     

政府支出与居民消费:替代或互补——基于非线性有效消费函数的实证

以非线性有效消费函数为基础,笔者构造了一个政府支出与居民消费的跨期替代模型,并利用1978年～2004年相关数据,实证研究了我国政府支出与居民消费的关系.研究结果表明,在短期内,我国政府支出与居民消费呈互补关系;但在长期内,我国政府支出与居民消费呈替代关系,即政府支出挤占居民消费支出.因此,在短期内,政府可以通过增加支出增加居民消费以提高社会总需求;但在长期经济均衡时,政府不宜采用支出政策来实现长期经济目标.     

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.
