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.     

Step Returns in Threshold Public Goods: A Meta- and Experimental Analysis

One important determinant of voluntary contributions to public goods is the value of the public good relative to that of the forgone private good. Isaac, Walker and Thomas (1984) formalized this relation in the Marginal Per Capita Return (MPCR) and demonstrated its influence on the provision of linear public goods. This paper develops a parallel concept, in the context of a threshold public good, the Step Return (SR). After providing a meta-analysis of the effect of SR in previous experiments, we compare contributions in threshold public goods games with low, medium and high SRs. Results show that subjects respond to the SR in this setting just as they respond to the MPCR in the linear public goods setting: higher SRs lead to more contributions.     

On the Private Provision of Two or More Public Goods

We extend the simple model of voluntary public good provision to allow for two or more public goods, and explore the new possibilities that arise in this setting. We show that, when there are many public goods, voluntary contribution equilibrium typically generates, not only too low a level of public good provision, but also the wrong mix of public goods. We also analyze the neutrality property in the more general setting, and extend a neutrality proposition of Bergstrom, Blume, and Varian (1986) .     

公共品供给机制:作用边界变迁及影响因素

公共品供给机制是从供给主体和运行机理的角度抽象出的公共品供给模式,包括政府供给、市场供给和自愿供给.某一公共品的供给方式不是一成不变的,其供给机制的作用边界处于变迁之中,主要表现为政府供给与私人供给的相互转化.在公共品供给机制的变迁中,公共品的性质特征、技术进步、政府职能理念、公平效率准则、政府政策倾向、需求状况以及私人资本规模都产生了一定的影响作用.     

Public goods provision,inequality and taxes

The impact of redistributive policies on voluntary contributions is still not well understood. While a higher level of redistributive taxation decreases the price of voluntary giving, it also changes the income distribution by decreasing income inequality. This paper provides a controlled laboratory experiment to investigate the net impact of the tax rate on public goods provision. The experimental findings show that while the participants decrease their voluntary contributions as the pre-tax income distribution becomes more equal, they increase their contributions with taxation. These findings have important implications for government policies regarding privately provided public goods.     

Non‐Governmental Public Norm Enforcement in Large Societies as a Two‐Stage Game of Voluntary Public Good Provision

In small groups, norm enforcement is achieved through mutual punishment and reward. In large societies, norms are enforced by specialists such as government officials. However, not every public cause is overseen by states, for instance those organized at the international level. This paper shows how nongovernmental norm enforcement can emerge as a decentralized equilibrium. As a first stage, individuals voluntarily contribute to a nongovernmental agency that produces an incentive system. The second stage is the provision of a public good on the basis of private contributions. The incentive system increases contributions by means of public approval or disapproval of behavior. It is shown that, even in large populations, nongovernmental norm enforcement can be supported in a noncooperative equilibrium of utility‐maximizing individuals. This result is in sharp contrast to those obtained in the standard situation of voluntary provision of an intrinsic public good which—without altruism or related motives—is eroded by free‐riding. Reliance on altruistic behavior is not required in supplying the second‐order public good “norm enforcement” in large societies.     

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.     

Tax Competition,Investment Irreversibility and the Provision of Public Goods

This article studies the effects of tax competition on the provision of public goods under business risk and partial irreversibility of investment. As will be shown, the provision of public goods changes over time and also depends on the business cycle. In particular, under source‐based taxation, in the short term, public goods can be optimally provided during a downturn. The converse is true during a recovery: in this case, they are underprovided. In the long term, however, tax competition does not affect capital accumulation. This means that the provision of public goods is unaffected by taxation.     

Voluntary Provision of Public Goods and Technology

This paper highlights issues in the theory of voluntary provision of public goods, building on the investigation by Peacock in connection with the contributions by Coase and Buchanan. Our goal is twofold. We first draw attention to the early literature investigating the provision of public goods and to the successive theoretical analysis. We then focus on the impact of technology on supply and demand. Examples of different types of public goods are provided, with special attention to the cultural sector, to investigate whether and how technology affects the efficiency and the effectiveness of the related public goods provision. The implementation and exploitation of technological advancements are investigated in view of the role of different actors (public, private) at different levels of government.     

PRIVATE PROVISION OF PUBLIC GOODS AND INFORMATION DIFFUSION IN SOCIAL GROUPS

I describe a dynamic model of costly information sharing where private information affecting collective‐value actions is transmitted by social proximity. Individuals make voluntary contributions toward the provision of a pure public good, and information transmission about quality of provision is a necessary condition for collective provision to take place in a stationary equilibrium. I show that unlike in the case of private goods, better informed individuals face positive incentives to incur a cost to share information with their neighbors and that these incentives are stronger and provision of the pure public good greater the smaller are individuals' social neighborhoods.     

Strategic Complementarity in the Dynamic Private Provision of a Discrete Public Good

Individual voluntary contributions to a discrete public good are shown to be strategic complements in a dynamic private provision game. This is in contrast to a public good that can take on any value in a continuum where they are strategic substitutes.     

Consuming your way to efficiency: Public goods provision through non-distortionary tax lotteries

We revisit the classical result that taxation of private consumption is distortionary and therefore precludes the efficient provision of public goods. We introduce a nonlinear consumption tax which we call a ‘tax lottery’. Under this scheme, an ad-valorem consumption tax is supplemented with a lottery in which consumers can win cash prizes. The winning probabilities in this lottery depend on all consumers' private good consumption decisions. We show that for a given ad-valorem tax, an appropriately designed lottery can implement an efficient allocation in pure-strategy Nash equilibrium. The lottery component corrects the distortion in private consumption due to the ad-valorem tax, while the resulting tax revenue is sufficient to efficiently provide the public good and pay out the lottery prize.     

Collective Choice and Voluntary Provision of Public Goods*

Some public goods are provided entirely with private contributions, others with a mixture of public and private funding, and still others are entirely publicly funded. In order to study this variation, a model of dual provision is developed that endogenizes public and private funding. Households vote over an income tax that finances public supply of the good and on whether to permit private contributions. While permitting private contributions may lead to a reduction in total provision, a majority always favors permitting private contributions. Results are developed for small and large economies, and the relevance of nonexcludability and noncongestion are investigated.     

Public goods with congestion

I consider the problem of the efficient provision of a congested (limited capacity) public good in a setting with asymmetric information. I show, in particular, that when the capacity of the good is limited, in a wide class of economies it is possible to construct an incentive compatible mechanism that always produces the good at the efficient level, balances the budget and satisfies voluntary participation constraints. This result is in contrast with the corresponding impossibility result for pure public goods due to Mailath and Postlewaite (Rev. Econ. Stud. 57 (1990) 351-359) and Rob (J. Econ. Theory 47 (1989) 307-333).     

A Dynamic Tiebout Theory of Voluntary vs. Involuntary Provision of Public Goods

This paper considers a dynamic model of Tiebout-like migration between communities that utilize distinct allocation procedures for public goods. At issue is whether voluntary or compulsory procedures are more likely to prevail over time. We model infinitely lived individuals who make repeated, sequential location decisions over one of two communities. Each community uses a distinct mechanism for allocating public goods. The first is one in which contributions are given voluntarily by the citizenry of the community. The second is a compulsory scheme by which individuals are taxed proportionately to wealth with the tax determined by a majority vote. Opportunities to accumulate wealth exist via accumulation of public capital.
The Markov Perfect equilibria of the dynamic game are studied. Our main result shows that when accumulated wealth converges to a steady state, individuals' locational choices eventually "select" the involuntary provision mechanism. This holds despite the fact that unanimous location in the voluntary provision community may in many cases remain as a Nash equilibrium of the static game each period. We also describe conditions under which voluntary provision survives. These conditions require that accumulation of capital fails to decrease wealth dispersion over time. The results are shown to be consistent with findings relating inequality to school choice.     

Public goods provision,redistributive taxation,and wealth accumulation

This paper presents an extension of a static model of public goods provision with redistributional taxation, as described by Uler [Journal of Public Economics 93 (3–4), pp. 440–453], as a dynamic model of wealth accumulation. Intertemporal consumption and saving behavior strongly affect the relation between redistributive taxation and charitable contribution. Indeed, the analyses presented herein reveal that more patience (i.e. higher saving) engenders a lower redistributional tax rate. However, the optimal redistributive tax rate is not zero because redistributive taxation improves the efficiency of providing public goods that are not improved by balanced growth. This paper fills the gap separating static analysis and dynamic analysis, and generalizes the results presented by static analysis.     

On the marginal cost of public funds and the optimal provision of public goods

This paper argues that, in models with heterogeneous agents, the concept of the marginal cost of public funds (MCPF) will only be useful if it is compared with an analogous concept for the benefit side. The MCPF does not assume a unique value and is not particularly illuminating in and out of itself. Also gone is the benchmark status of MCPF = 1. Turning to the provision of public goods, using a mechanism design approach, the paper constructs a two-stage proof for Kaplow's [Kaplow, L., 1996. The optimal supply of public goods and the distortionary cost of taxation. National Tax Journal 49, 513–533.] proposition concerning the “irrelevance” of labor supply and distributional concerns in public good provision. This highlights the two fundamental ingredients for his result. First, the provision of public goods per se, when it satisfies the Samuelson's rule, is only potentially Pareto-improving. Second, the actual Pareto improvement will materialize when, or if, one reforms the income tax structure. If the reform is not forthcoming, the decision on public goods provision must rely on redistributional concerns. Finally, the paper generalizes Broadway and Keen's [Boadway, R., Keen, M., 1993. Public goods, self-selection and optimal income taxation. International Economic Review 34, 463–478.] result to a model with many types of agents, many private goods and without making any assumptions regarding which self-selection constraints are or are not binding.     

Redistribution and Provision of Public Goods in an Economic Federation

This paper concerns redistribution and public good provision in an economic federation with two levels of government: a local government in each locality and a (first mover) central government. Each locality is characterized by two ability‐types, and the ability‐distribution differs across localities. The central government redistributes via a nonlinear income tax and a lump‐sum transfer to each local government, while the local governments use proportional income taxes and provide local public goods. We show how the redistributive role of taxation is combined with a corrective role, and how the central government can implement the second best resource allocation.     

Factor Endowments and the Private Provision of Public Goods

The paper examines the consequences of increasing the size of the community in the standard model of the private provision of public goods when costs are variable. In contrast to an economy with fixed costs, the provision of the public good can fall with a larger community, and an increased provision of the public good is neither a necessary nor a sufficient condition for individual utility to rise. The paper also contributes to the literature on immiserizing growth in that it shows that capital accumulation can possibly result in lower utility for all individuals.     

Retailing public goods: The economics of corporate social responsibility

This paper explores the feasibility and desirability of Corporate Social Responsibility (CSR). We identify CSR with creation of public goods or curtailment of public bads. Using a model with profit-maximizing firms, the paper shows that there is a direct parallel between CSR and traditional models of private provision of public goods. Indeed, firms that use CSR will produce public goods at exactly the same level as predicted by the standard voluntary contribution equilibrium for public goods. We compare CSR with government provision and charitable provision, discussing when CSR by private for-profit firms could have a comparative advantage in dealing with public goods provision.
