Public Good Provision Under Monopolistic Competition

This paper presents a model of voluntary private provision of public good under monopolistic competition following Pecorino. Consumers prefer product varieties and a public good. Marginal utility of income depends inversely upon the aggregate consumption of private goods in this model. As population size increases, aggregate consumption of private goods goes up and marginal utility of income falls. This explains the positive relationship between population size and public good provision. Any technological changes in the production of private goods are shown to be neutral to the aggregate provision of public good. These results are in contrast to Pecorino.     

Public goods, merit goods, and the relation between private and government consumption

In this paper, we investigate the relation between public and private consumption, by constructing a general government spending data set, by function, for 12 European countries. In particular, we split government consumption into two categories. The first category—“public goods”—includes defence, public order, and justice. The second category—“merit goods”—includes health, education, and other services that could have been provided privately. Equations from a relatively general permanent income model are estimated by GMM. The estimates are fairly robust in showing that public goods substitute while merit goods complement private consumption. However, the relation between merit goods and private goods turns out to be stronger than that between public goods and private goods. Thus, in the aggregate government and private consumption are complements.

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。     

Consumption multipliers of different types of public spending: a structural vector error correction analysis for the UK

The aim of this paper is to investigate the relationship between government spending and private consumption in the UK, for which there is scarce previous empirical evidence. We disaggregate public expenditure into three categories and search for the corresponding private consumption multipliers. Our analysis is based on the estimation of a structural vector error correction model with quarterly non-interpolated data for the period 1981:1–2007:4. Initially, we estimate negative but barely significant effects on consumption of shocks to total public spending. Then, using the public spending breaking down, we find that while shocks to public wages crowd-out private consumption as predicted by neoclassical models, shocks to the non-systematic component of social spending and government purchases of goods and services generate a positive reaction, so to crowd-in private consumption. Thus, the qualitative and quantitative dimensions of fiscal multipliers on private consumption change across different public spending categories. Our findings suggest that any empirical support of competing theoretical models on the issue would benefit from a disaggregation of government expenditure, rather than focusing on the aggregate measure.     

The general equilibrium effects of fiscal policy: Estimates for the Euro area

This paper describes a dynamic stochastic general equilibrium model featuring a fraction of non-Ricardian agents in order to estimate the effects of fiscal policy in the Euro area. The model takes into account distortionary taxation on labor and capital income and on consumption, while expenditures are broken down into purchases of goods and services, compensation of public employees and transfers to households. A newly computed quarterly data set of fiscal variables is used. Our results point to the prevalence of mild Keynesian effects of public expenditures. In particular, although innovations in fiscal policy variables tend to be rather persistent, government purchases of goods and services and compensations for public employees have small and short-lived expansionary effects on private consumption, while innovations in transfers to households show a slightly more sizeable and lasting effect. The effects are more significant on the revenue side: decreases in labor income and consumption tax rates have sizeable effects on consumption and output, while a reduction in capital income tax favors investment and output in the medium run. Finally our estimates suggest that fiscal policy variables contribute little to the cyclical variability of the main macro variables.     

Does Government Expenditure Crowd Out Private Consumption in Italy? Evidence from a Microeconomic Model

An abnormal expansion of the public sector may create serious problems to the market economy, as the literature suggests. This issue is quite important in countries such as Italy where the size of the public sector and of its debt are quite relevant. In this paper a model, in the microeconomic tradition, is developed and applied to the italian economy using a quite general utility function to represent consumer's behaviour. The aim of the article is to set up a methological framework in which to test for the hypothesis that the provision of public and impure public goods crowds out private consumption. The main result of the analysis is that, in Italy, traditional public goods play a neutral role in expenditure decisions while impure public goods crowd out private consumption. This crowding out is created by over-production of these services; merit goods are direct complements to a wide range of private goods, but this beneficial effect is more than offset by the negative income effect related to their financing.     

ON THE EFFECTS OF DIFFERENT PATTERNS OF PUBLIC CONSUMPTION EXPENDITURES

The multiplier effects resulting from an isolated increase in the level of public consumption within different public branches are investigated and the policy implications are discussed. The article begins with a theorethical analysis which shows why and in which ways these multipliers can be expected to differ between public branches. Thereafter, an empirical investigation is given, based on simulations with an econometric model of the Swedish economy. In this model the public activities are divided into 13 different public branches. The effects of an increase in public consumption on employment, imports and private consumption are found to differ considerably depending on which branch of the public sector is expanded. Some implications for short run stabilization policy are discussed. The article ends with a special analysis of the implications for a medium term planning problem: the trade off between private and public consumption growth. This analysis throws new light on the old topic "private or public consumption". In an economy with highly differentiated production in the public sector the trade-off is shown not to be unique. The sacrifice of private consumption growth corresponding to a given growth of public consumption expenditures will vary considerably according to the distribution of the public consumption growth within the different branches of the public sector.     

The Penalties of Inefficient Infrastructure

In most developing countries, irrigation, road, and power networks are not in good condition. In Latin America, for example, the effectiveness of such public infrastructure is only about 74% of that of industrialized countries. Low effectiveness imposes a cost on these countries in terms of forgone output. This paper develops a general–equilibrium model to study the long–run consequences of ineffective infrastructure. The model is solved numerically using parameters from seven Latin American countries. Results show that the long run penalty of ineffective infrastructure is about 40% of steady–state real GDP per capita. Raising effectiveness is shown to have sizable positive effects on income per capita, private investment, consumption, and welfare. Nevertheless, policymakers instead usually emphasize building new infrastructure. If effectiveness is low in the existing infrastructure network, new infrastructure investments can negatively affect per–capita income, private investment, consumption, and welfare.

A Permanent Income Model of Public Consumption

This paper tests the permanent income hypothesis (PIH) for public consumption. Unlike private agents, a government is a representative national, infinitely-lived agent that usually faces no liquidity constraints. Thus, the expectation is that the PIH restrictions should not be rejected for public consumption. However, using U.S. data, the paper is unable to find evidence supporting the permanent income model of public consumption. Public consumption is found to be sensitive to lagged public income and too smooth relative to permanent public income. The results therefore cast doubt on the characterization of the public sector as a social welfare optimizing agent.     

The long run relationship between private consumption and wealth: common and idiosyncratic effects

We investigate the long run relationship between private consumption, disposable income and wealth approximated by equity and house price indices for a panel of 15 industrialized countries. Consumption, income and wealth are cointegrated in their common components. The impact of house prices exceeds the effect arising from equity wealth. The long run vector is broadly in line with the life cycle permanent income hypothesis, if house prices are allowed to enter the relationship. At the idiosyncratic level, a long run equilibrium is detected between consumption and income, i.e. the wealth variable can be excluded. The income elasticity in the idiosyncratic relationship is significantly less than unity. Hence, the presence of wealth effects in consumption equations arises from the international integration of asset markets and points to the relevance of risk sharing activities of agents. Without sufficient opportunities, an increase in national saving rates would be expected, leading to a lower path of private consumption expenditures.     

The impact of targeting policy on spouses’ demand for public goods,labor supplies and sharing rule

This paper studies the impact of targeted unconditional cash transfers on the spouses’ demand for public goods, labor supplies and sharing of resources. We estimate a collective labor supply model with distributional factors which is extended to include preferences over marketable public goods (including child goods). In this way, unlike previous research, we consider the impact of such transfers on the intrahousehold allocation of resources and distinguish between the labeling and recipient effects. We exploit the UK experience and find evidence in favor of the collective model with separable preferences over labor supplies and public goods. This finding implies a recipient effect and not a labeling effect of child benefits. Given the household’s unearned income, the bigger the wife’s bargaining power, the more the resources allocated to public goods (including child goods) and the wife’s private consumption. The results can be useful in the design of family policy which aims to improve the relative welfare of children within the family and alleviate any intrahousehold consumption inequalities.     

Imperfect Tax Compliance and the Optimal Provision of Public Goods

Our aim in this paper is to investigate whether the presence of imperfect income tax compliance affects the optimal provision of public goods within a framework in which public expenditure is financed by a general income tax that also accomplishes redistributive goals. We first derive the income tax structure, and then a generalized Samuelson rule. We argue that, under imperfect income tax compliance, it is desirable to distort public–good supply downwards, in the sense that the sum of marginal rates of substitution between public and private consumption must exceed their marginal rate of transformation.     

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.     

Bergstrom,Blume, and Varian: Voluntary contributions and neutrality

Bergstrom, Blume, and Varian provided a neutrality result for the private provision of public goods that has inspired a considerable literature. The result has significant implications for income redistribution and broader policy interventions. This paper reviews the basic result and its applications, and discusses extensions to general private provision economies.     

Relative price shifts,economies of scale and poverty during economic transition1

Economic transition is associated with significant shifts in relative prices between private and public goods. If, as a result, public goods claim a larger share of total expenditures, economies of scale in consumption increase. We show how relative price changes might alter the welfare of different‐sized households in the short run and over time. We illustrate, for a selection of transition economies, that conventional poverty profiles are quite sensitive to assumptions made about economies of scale in consumption. In particular, the common view that large households with many children are poor relative to small households (such as those comprising the elderly) is shown to be highly non‐robust.     

Should governments stop subsidies to private goods? Evidence from rural Latin America

This paper empirically documents the effects of subsidizing private goods to the detriment of the government's supply of public goods. We use a new data set from the rural sector in fifteen Latin American countries over the period 1985–2001 collected using a methodology that allows us to separate government subsidies to private goods from expenditures in the provision of public goods. The econometric evidence shows that the government's decision to subsidize either private or public goods has dramatic consequences for economic development. Reducing the share of subsidies to private goods (or, equivalently, increasing the share of public goods) in the government's budget has, ceteris paribus, a large and significant positive impact on rural per capita income, reduces certain undesirable environmental effects associated with output expansion, and contributes to poverty reduction.     

Income Distribution, Taxation, and the Private Provision of Public Goods

This article investigates the role of taxation when public goods are privately provided. Externalities between consumers via the public good are shown to cause kinks in social indifference curves. As a result, a government restricted to income taxation should engineer enough inequality to ensure there are some non-contributors to the public good. Whether commodity taxation changes this conclusion depends on the extent to which consumers "see through" the government budget constraint. If they can, inequality should still be sought. When they cannot, in contrast to the case of an economy with only private goods, commodity taxation can be used in conjunction with income transfers to achieve the first-best.     

Social security,saving, and macroeconomics

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.     

Existence of equilibrium and stratification in local and hierarchical Tiebout economies with property taxes and voting

Summary. This paper present the first fully closed general equilibrium model of hierarchical and local public goods economies with the following features: (i) multiple agent types who are endowed with both some amount of private good (income) and a house, who are mobile between houses and jurisdictions, and who vote in local and national elections; (ii) multiple communities that finance a local public good through property taxes which are set in accordance with absolute majority rule; and (iii) a national government that produces a national public good financed through an income tax whose level is determined through majority rule voting. In contrast to previous models, no overly restrictive assumptions on preferences and technologies are required to prove the existence of an equilibrium in the presence of property taxation and voting. Thus, the existence of an equilibrium is proved without any of the major restrictions used in the past, and sufficient conditons for stratification of agents into communities based on their public good preferences and their wealth levels are found. This model lays the groundwork for a positive applied analysis of local public finance and intergovernmental relations. It furthermore builds the foundation for the first parameterized computable general equilibrium model of local public goods and fiscal federalism.
