Voluntary purchase of public goods

This paper examines the application of Buchanan's ‘independent adjustment’ model of public good provision to individual donations to voluntary or non-profit organizations. An individual's donation function is a simple transformation of the Marshallian demand function; consequently donation functions ‘reveal,’ in principle, preferences for public goods. The existence of a tax-subsidy system sustaining a Pareto optimal level of provision is demonstrated, and the relationship to the existing subsidy scheme in the U.S. is examined. Finally, two implications of the model suggest that it is not appropriate as a representation of actual donor behavior.     

Why societies need public goods

The most distinctive features of public goods are usually understood to be the difficulty of excluding potential beneficiaries and the fact that one appropriator’s benefits do not diminish the amount of benefits left for others. Yet, because of these properties (non-excludability and non-rivalry), public goods cause market failures and contribute to problems of collective action. This article aims to portray public goods in a different light. Following a recent reassessment of public goods in political philosophy, this contribution argues that public goods are particularly suitable for sustaining a well-ordered society. Public goods contribute to social inclusion, they support the generation of the public, and they strengthen a shared sense of citizenship. This article scrutinizes these functions of public goods and offers a discussion of the interventionist thesis which states that governments should sustain public goods.     

Rent-seeking for pure public goods

In this paper we present a formal analysis of rent-seeking for public goods by two or more groups with different numbers of individuals. We begin by considering equally wealthy groups under risk neutrality, a case which constitutes our basic model. Several surprising and interesting results emerge from the analysis of this basic case. The problem is then extended to deal with (a) groups with different wealth levels, and (b) risk aversion. This last extension brings about a further crop of interesting and useful results.     

Why the intrinsic value of public goods matters

Abstract

Existing accounts of public-goods distribution rely on the existence of solidarity for providing non-universal public goods, such as the humanities or national parks. There are three fundamental problems with these accounts: they ignore instances of social fragmentation; they treat preferences for public goods as morally benign, and they assume that these preferences are the only relevant moral consideration. However, not all citizens unanimously require public goods such as the humanities or national parks. Public-goods distribution that is based only on citizens’ preferences, therefore, means that non-universal public good are at a constant risk of under-provision, and has negative implications for human flourishing. The paper, therefore, develops a complementary justification for the distribution of public goods, that decouples the distribution of public goods from ad hoc preferences, and grounds the distributive justification in the intrinsic value of these goods. There are three reasons to include intrinsic-value considerations in public-goods distribution: responding to crowding-out effects; promoting shared heritage and cross-fertilization. Finally, the intrinsic-value justification may indirectly promote solidarity. Thus, the intrinsic-value and the solidarity justifications need not be mutually exclusive, rather they can be mutually reinforcing.     

Private provision of public goods can be efficient

Economists have long believed that private provision of public goods will be inefficient, though recently some have argued that altruism may mitigate the inefficiencies. Without altruism, agents contribute to the point where marginal cost equals their private marginal benefits. With altruism, they contribute more and hence are closer to the point where marginal cost and total marginal benefits are equated. In an earlier paper (Bagnoli and Lipman, 1989), we showed that private provision need not be inefficient. In a very natural model of private provision without altruism, we showed that the set of (undominated perfect) equilibrium outcomes is identical to the core. Here we consider the effect of altruism on private provision. Altruism essentially creates more public goods because the well-being of others becomes a public good. We show that our model of private provision still has efficient equilibria under a wide variety of circumstances. Interestingly, the equilibria may be inefficient when agents are concerned about the effect of private provision on the distribution of wealth. Intuitively, the game we consider is a very powerful instrument for efficient private provision, but must be supported by other instruments if the set of public goods is expanded too far.We wish to thank Jim Andreoni, Ted Bergstrom, and an anonymous referee for helpful comments and to acknowledge financial support from the National Science Foundation through NSF Grant SES-8520296.

Government subsidies to private spending on public goods

This paper examines how the size of an efficient subsidy varies with the amount of free-riding and the presence of distorting taxation. Ironically, the existence of free-riding, where some individuals make no voluntary contribution at all, reduces the size of an efficient subsidy and makes a subsidy more attractive compared to direct taxation. For the gain to be significant, the number of donors must be extremely few in number. Even when the gains from a subsidy relative to direct taxation are small, a subsidy may dominate direct taxation because it can reveal an efficient level of the public good. The analysis distinguishes between traditional public goods such as national defense, and what I call transfer public goods, where members of society care about the consumption of a particular group in society such as the poor. I generalize the Samuelson (1954) results to derive conditions for efficiency in providing transfer public goods.     

A general model of rent seeking for public goods

This paper generalizes the model of collective rent-seeking over a public good. Expanding the rent seeker's consumption bundle to include preferences over the public good and a private good, our results suggest collective rent-seeking is positively related to group size. Although free riding exists within a group, there is not a one-for-one tradeoff. In addition, rent seeking increases with wealth. Finally, total effort expended by both groups increases if either group increases in membership size, except in the case of an extremely lopsided contest. The key condition underlying these results is that the marginal utility of the public good is not inversely related to the private good.     

Innovations in the provision of public goods and services

Current efforts at administrative reform in both developed and developing countries have invariably focused on the critical issue of provision of public goods and services. The accumulated experience and attendant innovations are therefore vast. Few attempts have been made to pull this experience together and draw salient features which might be of use to newcomers to the task of improving provision of public goods and services. This article draws on a panel of experts and government officials convened by the author who have reflected and/or experimented with innovative approaches to public good and service provision. After discussing the role of the state, market and civil society relative to public goods and services, the article lays out a set of basic institutional options for innovations in provision. The article concludes with some strategic considerations on the sequencing of steps to achieve successful market-based innovations in the provision of public goods and services in the context of the minimalist and the strong but restrained state. © 1998 John Wiley & Sons, Ltd.     

The second-order dilemma of public goods and capital accumulation

The second-order dilemma arises from each individual’s incentive to free ride on a mechanism to solve the public goods provision problem (the first-order dilemma). We show by a voluntary participation game that if the depreciation rate is low, public goods can be accumulated through voluntary groups for provision, and that the accumulation is effective in solving the second-order dilemma. This analysis also shows that population growth increases the accumulation of public goods in the long run.
