An examination of the available data reveals that the size of government varies considerably across time and countries. By making use of a simple general equilibrium model, this paper demonstrates that size of government is affected by the availability of capital and labour within an economy. Specifically, this paper utilises a model of a closed economy that produces one-private and one-public good. Both goods are produced by means of capital and labour. Production functions are subject to constant returns to scale and perfect competition prevails in all markets. The elasticity of substitution between the public and the private good is greater than unity and there is no international factor mobility in the initial equilibrium. The size of government is measured by total spending on the public good as a proportion of the total expenditure on the private and public goods. It is shown that capital (labour) inflow can decrease (increase) the size of government. Capital inflow increases welfare if the private good is relatively capital intensive whereas labour inflow increases welfare if the public good is relatively capital intensive. 相似文献

将政府财政支出分解为消费性支出和生产性支出,建立了政府消费性支出与私人消费之间、政府资本与私人资本之间的非线性替代关系函数。将政府公共生产性服务和公共消费性服务的双重角色加入动态随机一般均衡(DSGE)模型,分析不同经济结构下政府的双重角色对中国宏观经济的影响差异。实证结果显示:政府生产性支出的弹性系数正在变小,政府生产性支出对中国宏观经济的影响在逐渐消失;在合理监管下,政府消费性支出有利于改善和提高人们的生活质量,并且不会对私人投资产生挤出效应。因此,政府应加大对财政消费性支出的监管力度。 相似文献

This paper develops a simple general-equilibrium model of a closed economy. The economy under consideration produces two final goods, one private and one public, which are both produced with labor and an intermediate good under constant returns to scale. The intermediate good is produced by labor alone, and its production is subject to output-generated variable returns to scale. The public good can be interpreted as government spending on environmental quality, police protection, cultural activities, and publicly funded health care. The model is used to examine the impact of an exogenous change in labor supply on the size of the government, relative prices, and welfare. Within the context of the present study, an increase in labor supply can be attributed to either exogenous immigration or population growth. The model is also used to examine the relationship between the size of the country and the pattern of trade. 相似文献

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 总被引:1,自引:0,他引:1
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. 相似文献

We look at privatization in a general equilibrium model of a small, tariff‐distorted, open economy. There is a differentiated good produced by both private and public sector enterprises. A reduction in government production in order to cut losses from such production raises the returns to capital and increases the tariff revenue, which are welfare‐improving. However, privatization also leads to lower wages and possibly fewer private brands. This lowers workers’ welfare, which may make privatization politically infeasible. Privatization can improve workers’ welfare with complementary reforms, e.g., attracting foreign investment or trade liberalization. 相似文献

This paper examines the short-run effects of changing government expenditure on output, consumption and employment. It attempts to combine the Public-Finance and macroeconomic approaches to the analysis of fiscal policy by introducing government expenditure which is 'useful' in consumption into an ISLM-type macro model which is derived from the singleperiod maximizing decisions of households and firms and which includes a government budget constraint.
The principal conclusion is that the effects of fiscal policy on output and employment depend on the 'efficiency' of government expenditure. The more efficiently government expenditure meets consumption needs, the less effective is fiscal policy to the point where the fiscal-policy multiplier may be negative. 相似文献

In a simple model of production with an imported polluting resource and involuntary unemployment we consider the effects of energy taxes, holding the real wage constant, under differing levels of government expenditure and externalities. Simulations reveal conflict between the goals of net welfare, employment and profitability over much of the relevant parameter range, thus extending the usual discussion of multiple dividends. However, potential net welfare and employment gains are substantial for plausible parameters. The optimal energy tax declines as government expenditure rises and is less than the Pigovian tax for plausible externalities. 相似文献

We present a neoclassical economic model of the human right to water using a nonrenewable resource model inclusive of a backstop technology. The right is interpreted as a minimum consumption requirement the government is obligated to fulfill in the event that any one household cannot do so independently. Differing by income levels, households maximize utility by purchasing a composite consumption good and water from two distinct, government-owned sources. Facing physical and financial constraints, the government uses fiscal policy to address potential human rights violations. Reducing the analysis to two periods, we develop a novel approach to compare total welfare levels from a joint human rights and neoclassical economics perspective. We define a human rights welfare standard and discuss cases in which traditional social welfare measures would exceed, violate, or meet this standard. We thus offer a unique way to merge economic analysis with human rights research. 相似文献

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。 相似文献

Tax-favored contributions for financing some public goods may be a useful part of optimal nonlinear income tax and expenditure policy. There are two sides to the potential gain from subsidized donations. First, for a given level of public good provision, higher private donations from high earners than low earners eases the incentive compatibility constraint for donors and so can raise social welfare. This follows since considering a lower-paid job includes a perception of a drop in public good provision. Second, private donation reduces consumption, easing the resource constraint. This paper explores optimal policy, using first a model with standard preferences and then a model with a warm glow of giving. In addition to showing the conditions for the level of public goods, the paper considers the pattern of optimal subsidization across earnings levels. Analysis of optimal taxation with warm glow preferences is sensitive to the choice of preferences that are relevant for a social welfare evaluation. After considering optimal rules with formulations of social welfare which do and do not include warm glow utility, the paper considers the choice of normative criterion. Like the earlier literature, this paper assumes that organizing private donations is costless while tax collection has a deadweight burden. Since private charitable fundraising is very far from costless, the paper is an exploration of economic mechanisms, not a direct guide to policy. 相似文献

Tax Reform with Useful Public Expenditures 总被引:1,自引:0,他引:1
We examine the effects of tax reform in an endogenous growth with two types of useful public expenditures. The optimal fiscal policy shifts the tax base to private consumption and generally requires a change in the size of government. If a tax reform holds the size of government fixed to satisfy a revenue‐neutrality constraint, then the reform will be suboptimal; theory alone cannot tell us if welfare will be improved. For some model calibrations, we find that a revenue‐neutral consumption tax reform can result in large welfare gains. For other quite plausible calibrations, the exact same reform can result in tiny or even negative welfare gains as the revenue‐neutrality constraint becomes more severely binding. Overall, our results highlight the uncertainty surrounding the potential welfare benefits of fundamental tax reform. 相似文献

This study estimates empirically the employment effects if stronger tobacco control policies result in reduced consumption in South Africa. Since 1995, the government has committed itself to a stronger tobacco control policy and increased excise taxes. Yet policy makers are sensitive to the need to pursue this public health policy in a way that will minimize job losses. This study uses input-output methodology and four expenditure scenarios to estimate output and employment effects following such policies. The analysis suggests that net employment effects will be positive if consumption expenditure is switched from tobacco to other goods and services in the economy. Further, this study suggests that these policy implications for tobacco control and public health hold, if a country has a self-sufficient industry like South Africa. (JEL 118, D57) 相似文献

Arguing within the framework of a life-cycle hypothesis of consumption of the individual household, Martin Feldstein has claimed that a pay-as-you-go, unfunded social-security system implies a private-sector perception of wealth which both depresses private saving and raises aggregate consumption. But the effects in a macro-economic context are not the same. With less than full employment, perceived increments to private wealth in social security or any other government obligations should increase current and planned future consumption and saving, raising employment and output. With full employment, as long as monetary policy is appropriately accommodating, such increments to wealth should raise prices but leave all real variables, including capital accumulation, unaffected. Increases in social-security wealth would merely substitute for real private wealth in the form of explicit government bonds. Econometric estimates from corrected U.S. data on social security, public debt, income, and employment are consistent with these hypotheses. 相似文献

This paper implements and adapts the conceptual framework developed by Winters (2002) that identifies the transmission mechanisms between trade policy reform and household welfare outcomes. We make use of household panel data from Vietnam collected in two years, 1992–93 and 1997–98 that span the very earliest years of the reform period and its immediate after effects. Poverty dynamics are modeled using changes in consumption expenditure and poverty transition models. The trade effect is captured by a set of variables that are most likely to have an impact on rural poverty, namely prices of staples and employment in the export sector. We show that trade liberalization has a material and positive effect on rural household welfare and this trade effect is largely transmitted to the poor through the labor market channel. 相似文献

This study examines the effects of public expenditure on production activity and private consumption activity. An input-output model with consumption functions connected is used for evaluating the repercussions of public expenditure. Taking both production and consumption repercussions into account, it is concluded that in the year 1965 public expenditure generated 26 percent of domestic incomes and 18 percent of imports. Viewed in terms of the shares of different types of income generated, 72 percent of public expenditure goes to domestic income, and the remaining 28 percent to imports. Forty-five percent of public expenditure returns directly as income to general government. The study also examines the effects of public expenditure by industry and over time (1959 to 1965). 相似文献

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. 相似文献

We explore a novel channel through which government spending can stimulate consumption and welfare through its effects on aggregate productivity, without directly affecting either utility or production possibilities. In the presence of monopolistic competition and increasing returns to specialization, it is shown that government spending can partly alleviate the inefficiencies of monopolistic competition. This is because government spending generates an endogenous increase in total factor productivity by increasing the variety of intermediate goods. If the degree of increasing returns to variety is large enough, a rise in such wasteful government spending may increase consumption levels enough to increase welfare.

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. 相似文献

Price Premiums for Eco-friendly Commodities: Are ‘Green’ Markets the Best Way to Protect Endangered Ecosystems? 总被引:1,自引:0,他引:1
‘Green’ markets represent a means through which public goods can be privately provided. A green product is an impure public
good consisting of a private good (e.g., rain forest honey) bundled with a jointly produced public good (e.g., biodiversity
protection). In the context of ecosystem protection, popular green commodities include eco-tourism excursions, coffee grown
under forest canopies (‘shade-grown’), tagua nuts for buttons and ornaments, rainforest nuts and oils for cosmetic products,
and rain forest honey. We examine the dynamic efficiency of eco-friendly price premiums in achieving ecosystem protection
and rural welfare goals by contrasting the use of price premiums to the use of payments that are tied directly to ecosystem
protection. We demonstrate analytically and empirically that direct payments are likely to be more efficient as a conservation
policy instrument. Depending on the available funds, the direct payments may be better or worse than green price premiums
in achieving rural welfare objectives. If direct payments are not feasible for social or political reasons, we demonstrate
analytically and empirically that the price premium approach is likely to be more effective at achieving conservation and
development objectives than the currently more popular policy of subsidizing capital acquisition in eco-friendly commercial
activities. 相似文献
