Musgrave’s vision of the public sector: the complex relationship between individual, society and state in public good theory

Richard Musgrave introduced the notion of a public good after reading an obscure publication by Lindahl in German in 1910. His great contribution to knowledge was to provide a clear and comprehensive structure for thinking about the process of achieving an “optimal” allocation of resources across public and private goods based individual preferences and the role of government in that process. A number of ambiguities and issues in Musgrave’s vision remain only partially resolved including the need to incorporate “higher laws” or community values into the allocation process.      

‘Market failure’ arguments are a poor guide to policy

‘Market failure’ is frequently offered as a justification for government intervention in the economy. Proponents of interventions can point to almost limitless examples of markets which do not meet all the criteria for Pareto optimality and argue that government taxation, subsidies or regulation can perfect them, maximising social welfare. But comparing market outcomes with an unattainable and unidentifiable ideal is not useful in a world of imperfect knowledge and government failure. It is better to compare market outcomes against realistic alternatives. Furthermore, even within the market failure paradigm, concepts such as ‘public goods’ and ‘negative externalities’ are routinely misunderstood and inconsistently applied. This leads to predictably poor policy outcomes.     

On the cost-benefit of the regionalisation of the National Health Service

In this paper we analyse in formal terms the desirability of the regionalisation of a National Health Service. The policy consists of a devolution process, i.e. the increase in the health services provision to be decided by a region and financed by an increase in its revenues. The change is a marginal one, as it regards the part of supply of the health services exceeding a minimum standard, which for purposes of equity is maintained uniform in the national territory. As the central government is responsible for this component of the provision of health care (a federal “mandate”), the level of the said component is chosen by this authority and financed by federal taxation. Moreover, the government also applies an equalisation scheme based on the difference between a standard level of tax revenues and the revenues which the region is deemed able to raise for this purpose. Within the theoretical context of welfare improving reforms with distortionary taxation, we derive two conditions which focus on the regional, as well as the social, convenience of regionalisation.

Stackelberg leadership and transfers in private provision of public goods

We consider transfers in a Stackelberg game of private provision of a public good. It turns out that the agent who is the follower in the process of making voluntary contributions to a public good may have an incentive to make monetary transfers to the Stackelberg leader even in a situation where neither has a comparative advantage in making contributions to the public good. The Stackelberg leader is willing to accept such transfers if the actual contribution game is fully non-cooperative because the transfer generates a Pareto superior outcome. If the contributions in the Stackelberg equilibrium is the threat point of a possible cooperative Nash bargaining game, the Stackelberg leader will refuse to accept the transfer if she can.

Why Voters Veto Vouchers: Public Schools and Community-Specific Social Capital

This article explains voters‘ attachment to public education the public benefit of local schools accrues to adults, not children. Having children in local schools increases parents’ “community-specific social capital.” Through local school connections, parents get to know other adults in their community better, which in turn reduces the transaction costs of citizen provision of local public goods. Vouchers would disperse students from their communities and thereby reduce localized social capital. Empirical evidence supporting this also explains the rise and fall of Robert Putnam’s national indicators of social capital, which have moved in lock-step with the number of children per household.

Monopolistic Competition and Public Good Provision with By‐Product Firms

I develop a model in which the voluntary contributions mechanism for the provision of public goods totally breaks down in a large society. A by‐product firm sells a private good and uses its profits to provide a public good. By‐product firms compete with for‐profit firms in a monopolistically competitive industry. If the number of by‐product firms is proportional to the size of the society, then public good provision rises without bound as the society grows large. This stands in strong contrast to the results under the voluntary contributions mechanism.     

Capital structure,investment unanimity,and public goods: the case for social responsibility

This paper examines the concepts of optimal capital structure and investment in an economy where government’s role is the provision of a public good. That public good is financed through current tax revenues and the sale of government securities. Absent such complications, traditional finance theory has established the equivalence among (competitive) value maximization, unanimity, and Pareto optimality. In the setting of this paper, however, the market value of government securities is not determined by the value of public good production, and the correspondence between value maximization, Parto optimality, and unanimity will not generally hold without significant restrictions on the tax structure. Otherwise, value maximization is neither an optimal nor unanimously supported objective for the firm.     

Government Budgets and Public Services: Some Criteria for Determining the Sources and Levels of Public Goods, including Transport Services

Instances of non-optimal consumption of public goods and services can easily arise if individual demand curves are not identical. It does not follow, however, that the best solution to the problem of too little consumption is an increase in government expenditure. Special user charges and voluntary contributions of time, goods, and money on the part of persons that value public goods more highly than the general population have long been important ways of supplementing government spending for social goods. The work trip appears to be a good example of a service area where existing cost structures and pricing methods may be biased against the voluntary associations which are needed to make the United States less dependent on foreign oil. This bias could be corrected by using an income-tax-surcharge to help finance the fixed costs associated with mass transit and other types of work trip pooling arrangements.     

Altruism, redistribution and social insurance

The paper examines the influence of altruism on voluntary transfers and government redistribution in a simple model: two jobs of different productivity are assigned by chance to two individuals. Ex ante the individuals are identical, ex post they have different incomes. The first part of the paper examines voluntary transfers determined ex post or agreed upon ex ante in the absence of altruism. In the second part, the influence of altruism is examined. Altruism is modelled as a pure public good: the minimum consumption (or income, since there is only one consumption good). Both individuals can contribute to its provision, one person by earning wage income, the other by voluntary transfers. The ex ante solutions generally lead to higher expected welfare but create several incentive problems. Only lump-sum transfers are considered.

Tax Competition and Revelation of Preferences for Public Expenditure

This paper considers a federal country composed of local jurisdictions that differ in their inhabitants' tastes for public goods, and which finance local public expenditure through a source-based tax on capital income. The taste for public goods is the private information of local governments. The central government seeks an optimal policy, in which grants to local governments are conditioned on local tax rates. The uninformed central government seeks both to allocate capital efficiently among jurisdictions, and to induce jurisdictions to provide an efficient mix of private and public consumption. It is shown that there persist at this constrained optimum both some misallocation of capital and some violation of the Samuelson rule for optimal public good provision in every jurisdiction.     

Environmental degradation,self-protection choices and coordination failures in a North–South evolutionary model

Environmental degradation may lead agents to increase their work effort to replace the consumption of depleted free access environmental goods with that of private substitute goods. The rise in the activity level that follows may further deplete the environment, which in turn increases the production and consumption of substitute goods. Using a North–South evolutionary model, we show that the existence of a coordination failure among interacting heterogeneous agents may lead the economy towards Pareto-dominated attracting stationary states where individuals work and produce “too much” (i.e. more than socially optimal). Finally, we analyse possible welfare effects of transferring the environmental impact of Northern production to the South and show that such a policy may decrease welfare in both hemispheres.     

Growth and fluctuations: The role of public dividends and public spending

In this paper, we consider a discrete-time version of the endogenous growth model developed by Barro [Barro, R.J., 1990. Government spending in a simple model of endogenous growth. Journal of Political Economy 98, 103–125], but augmented in order to envisage a public participation in the production of private goods. Public dividends are invested in order to provide a public good; in turn, the public good plays a role of indispensable production externality and, eventually, of growth engine.For what concerns the production of private goods, we find that an optimal policy is always based on a positive participation of the government as shareholder; also, when growth is slow, a public intervention or large substitution effects stabilize the economy.A right mix of short-run services and long-run infrastructures is suggested in slow economies to rule out expectation-driven fluctuations. Infrastructures are mainly recommended in presence of moderate income effects, while services are recommended in presence of strong income effects.     

Does government ideology influence budget composition? Empirical evidence from OECD countries

This paper examines whether government ideology has influenced the allocation of public expenditures in OECD countries. I analyze two datasets that report different expenditure categories and cover the time periods 1970–1997 and 1990–2006, respectively. The results suggest that government ideology has had a rather weak influence on the composition of governments’ budgets. Leftist governments, however, increased spending on “Public Services” in the period 1970–1997 and on “Education” in the period 1990–2006. These findings imply, first, that government ideology hardly influenced budgetary affairs in the last decades, and thus, if ideology plays a role at all, it influences non-budgetary affairs. Second, education has become an important expenditure category for leftist parties to signal their political visions to voters belonging to all societal groups.     

Monotonic extensions on economic domains

The property of “monotonicity” is necessary, and in many contexts, sufficient, for a solution to be Nash implementable (Maskin 1977). In this paper, we follow Sen (1995) and evaluate the extent to which a solution may fail monotonicity by identifying the minimal way in which it has to be enlarged so as to satisfy the property. We establish a general result relating the “minimal monotonic extensions” of the intersection and the union of a family of solutions to the minimal monotonic extensions of the members of the family. We then calculate the minimal monotonic extensions of several solutions in a variety of contexts, such as classical exchange economies, with either individual endowments or a social endowment, economies with public goods, and one-commodity economies in which preferences are single-peaked. For some of the examples, very little is needed to recover monotonicity, but for others, the required enlargement is quite considerable, to the point that the distributional objective embodied in the solution has to be given up altogether.

Natural and double implementation of public ownership solutions in differentiable production economies

This paper examines the implementation of two public ownership solutions in convex production economies with differentiable production functions. The two public ownership solutions we focus on are the proportional and equal benefit solutions. Two “natural” mechanisms which doubly implement the proportional and equal benefit solutions respectively in Nash and strong Nash equilibria are proposed without assuming free disposal.

Looking across borders: A test of spatial policy interdependence using local government efficiency ratings

Spatial patterns in (local) government taxation and spending decisions have received a lot of attention. Still, the focus on taxation or expenditure levels in previous studies may be incomplete. Indeed, (rational) individuals are likely to consider the level of spending on (or taxation for) public goods provision simultaneously with how much public goods they actually receive—thus assessing the ‘price/quantity’ of government policies. Therefore, the present paper argues that incumbents may want their ‘price/quantity’ ratio to be close to that in neighbouring regions. Analysing Flemish local governments' efficiency ratings for the year 2000 (which relate total spending to the quantity of locally provided public goods), we confirm the existence of neighbourhood effects in local government policies.

Selling to Socially Responsible Consumers: Competition and The Private Provision of Public Goods

We model firms as competing for socially responsible consumers by linking the provision of a public good (environmentally friendly or socially responsible activities) to sales of their private goods. In many cases, too little of the public good is provided, but under certain conditions, competition leads to excessive provision. Further, there is generally a trade-off between more efficient provision of the private and the public good. Our results indicate that the level of private provision of the public good varies inversely with the competitiveness of the private-good market and that the types of public goods provided are biased toward those for which consumers have high participation value.     

Dynamic voluntary provision of public goods with uncertainty: a stochastic differential game model

Fershtman and Nitzan (Eur. Econ. Rev. 35:1057–1067, 1991) presented a continuous dynamic public good game and solved the model for feedback Nash equilibria. Wirl (Eur. J. Polit. Econ. 12:555–560, 1996) extended the model and considered nonlinear strategies. Both models do not include uncertainty and hence neglect an important factor in the theory of public goods. We extend the framework of Nitzan and Fershtman and include a diffusion term. We consider two cases. In the first case, the volatility of the diffusion term is dependent on the current level of the public good. This set-up will in principle lead to the same type of feedback strategies computed under certainty. In the second case, the volatility is dependent on the current rate of public good provision by the agents. The results are qualitatively different. We provide a detailed discussion as well as numerical examples. In particular, we show that in both cases uncertainty signifies the free rider effect.     

Voluntary contributions to multiple public goods in a production economy with widespread externalities

In a production economy, multiple public goods are produced by firms in competitive markets, and provided by the government together with contributions from consumers. There are widespread externalities: all consumers’ consumption and contributions and all firms’ production enter into utility functions. Public goods can be imperfect substitutes or complements, and they can be local public goods or club goods. Zero bounds that require consumers to make nonnegative contributions complicate the differentiable approach. Applying the transversality theorem for smooth economies in a regular parameterization, we obtain the existence of equilibrium in such an economy, and generically equilibria are regular and locally unique.
