A Core‐Equilibrium Convergence in a Public Goods Economy

This paper shows a core‐equilibrium convergence in a public goods economy where consumers' preferences display warm glow effects. We demonstrate that if each consumer becomes satiated to other consumers' provision, then as the economy grows large the core shrinks to the set of Edgeworth allocations. Moreover, we show that an Edgeworth allocation can be decentralized as a warm glow equilibrium.     

Information Advantage in a Public Good Economy with Multiplicative Structure of Utilities

This paper extends results on information advantage in Cournot oligopoly to a public good economy with uncertainty and private information where the state‐dependent utilities have a multiplicative structure. We show that in a Bayesian–Nash equilibrium where consumers’ contributions are positive in all states of nature, a consumer with superior information is rewarded with a higher ex ante expected utility. Our counter example shows that in the case where one consumer does not contribute, information disadvantage might emerge. Thus, the interiority assumption is essential to obtain our results.     

On the Frequency of Interior Cournot–Nash Equilibria in a Public Good Economy

In a public good economy the distribution of initial income is an important determinant of how many individuals contribute to the public good in Cournot–Nash equilibrium. In this paper, first a simple formula is derived that provides a measure for the size of the set of income distributions leading to an interior Cournot–Nash equilibrium in which all individuals contribute to the public good. Furthermore, we give an estimate for the frequency that all members of a certain subgroup of the population are contributors.     

Equilibrium Existence and Uniqueness in Public Good Models: An Elementary Proof via Contraction

This paper presents a proof for existence and uniqueness of a Nash equilibrium of a public good model that exploits a simple contraction mapping. The proof establishes both existence and uniqueness in a single exercise that provides intuition about sufficiency. The method of proof is applied not only to the basic pure public good model but also to the impure model. In the latter model, income normality does not play the same pivotal role for existence and uniqueness.     

Federalism as a Public Good

This paper suggests that stabilizing federalism is like solving a public good provision problem. It reviews results in the public good provision literature that are relevant for federalism, and discusses the implications of these results for the institutional design of federalism.

Tariff Rate as a Public Good

If domestic firms lobby for protection, the tariff rate is a public good to all domestic firms, whether they engage in lobbying or not. This paper analyzes how the endogenous tariff rate as a public good depends on the group size in two‐stage lobbying models. The result depends not only on whether domestic firms lobby cooperatively or not, but also on whether domestic firms incur indirect lobbying costs or not. This paper shows that if free riding is not very serious and if the number of domestic firms is small compared to the number of foreign firms, entry of a domestic firm is likely to increase the equilibrium tariff rate.     

An Institutionalist Vision of a Good Economy

The current crisis in global capitalism and the wide-ranging problems that have been caused by the promulgation of a regime of deregulation of goods, services, and labor markets across the globe, but especially in the United States over the past thirty years, may indeed prove to be the end of the neoliberal era. Thus it is an opportune time to reconsider how the global economy could be restructured along more equitable and progressive lines. This paper will present the institutionalist vision of just such a good economy, building on the ideas of Veblen, Ayres, Commons, and Galbraith. The institutionalist vision of a good economy is productive but also non-invidious, democratic but also pragmatic, egalitarian but also efficient. The good economy must therefore be embedded in key social institutions, and be regulated appropriately to preserve the most beneficial social and cultural institutions. The good economy must, furthermore, be a full-employment economy, with jobs available to all who are capable of making productive contributions to their society and to enable those who labor to work in decent conditions. Finally, the good economy must provision all its members with the necessary means of subsistence for them to achieve their human aims.     

Optimal Nonlinear Redistributive Taxation and Public Good Provision in an Economy with Veblen Effects

This paper deals with the consequences of the assumption of negatively interdependent preferences for the shape of the optimal nonlinear income tax and the efficient level of public good provision in a setting where the agents' market ability is private information. The analysis points out that the terms added in the tax formulas due to the presence of Veblen effects might justify a reduction in the optimal marginal tax rates faced by the different individuals. Also, the desirability of negative marginal tax rates cannot be ruled out. With respect to the issue of the optimal level of public good provision, I derive a modified Samuelson rule and highlight the fact that the Veblen‐based part of the formula might require to distort downwards the efficient level of public good provision.

Destructive behavior in a Fragile Public Good game

Socially destructive behavior in a public good environment–like damaging public goods–is an underexposed phenomenon in economics. In an experiment we investigate whether such behavior can be influenced by the very nature of an environment. To that purpose we use a Fragile Public Good (FPG) game which puts the opportunity for destructive behavior (taking) on a level playing field with constructive behavior (contributing). We find substantial evidence of destructive decisions, sometimes leading to sour relationships characterized by persistent hurtful behavior. While positive framing induces fewer destructive decisions, shifting the selfish Nash towards minimal taking doubles its share to more than 20%.     

Public Good Mix in a Federation with Incomplete Information

We analyze a model of resource allocation in a federal system in which the center transfers real resources between member states. The center is assumed to be unable to observe the precise value of the cost differences across jurisdictions that motivate the transfers. Moreover, the center cannot observe the output levels of the individual local public goods provided by the jurisdictions, but must condition its transfers on a coarse aggregate of expenditures on public goods. We find that when the jurisdiction with private information realizes a high unit cost, it is generally worthwhile for the center to allow it a level of expenditure on public goods that differs from the "first best" level. However, whether that level is higher or lower than its first best level depends on the magnitudes of demand parameters for the local public good.     

Finitely Repeated Voluntary Provision of a Public Good

This paper theoretically explores the voluntary provision of a public good when either one of the following holds: (i) agents’ utility is the sum of their monetary earnings and a nonmaterial component, or (ii) agents’ exhibit satisficing behavior. We show that a small degree of either nonmaterial payoffs or satisficing behavior can generate large contributions in a finitely repeated game, even if the incentive to free‐ride on others’ contributions calls for negligible public good provision in the static game. The equilibrium is characterized by a sharp decline in contributions toward the end of the game. Several comparative results regarding group size and technology are consistent with laboratory data obtained in experimental studies. The model also predicts the restart effect observed in previous experiments.     

Aggregative Public Good Games

We exploit the aggregative structure of the public good model to provide a simple analysis of the voluntary contribution game. In contrast to the best response function approach, ours avoids the proliferation of dimensions as the number of players is increased, and can readily analyze games involving many heterogeneous players. We demonstrate the approach at work on the standard pure public good model and show how it can analyze extensions of the basic model.     

Public Good Contributions Between Communities

The four fundamental determinants of voluntary contributions to public goods are taste, community size, wealth, and wealth distribution. This paper argues that for policy purposes it is important to discriminate between the four hypotheses. To do this, it is necessary to consider the comparative static effects of the above determinants not only on total contribution, but also on per capita contribution and the participation rate. Furthermore, just as members of a smaller community would contribute more than their identical counterparts in a larger community, we show that members of a community that has more poor members would also contribute more than their identical counterparts in a community that has more rich members.     

Sharing the Cost of a Public Good without Subsidies

We study the construction of a social ordering function for the case of a public good financed by contributions from the population. We extend the analysis of Maniquet and Sprumont (2004) to the case when cost shares cannot be negative, i.e., agents cannot receive subsidies from others. We adapt the Maniquet–Sprumont defense of public good welfare egalitarianism to this context. Weakening their Free Lunch Aversion axiom and adding a continuity requirement allows us to characterize the public good welfare maximin social ordering function.     

Equilibrium Growth in a Small Economy Facing an Imperfect World Capital Market

A growth model of a developing economy facing an upward-sloping curve of debt is analyzed. Equilibrium is characterized by transitional dynamics in which consumption, capital, and debt converge to a common growth rate. The adjustment is through the debt-capital ratio, which drives the borrowing rate to a level at which growth rates are equalized. The economy is subject to two externalities: a production externality associated with government expenditure, and a financial externality associated with the upward-sloping supply of debt. The tax structure that enables the decentalized economy to attain the first-best equilibrium is characterized.     

Pareto-improving Immigration in an Economy with Equilibrium Unemployment

A dynamic two-country labour matching economy is presented. Workers decide whether to search in their native country or look for a job abroad (bearing an additional cost). The number of vacancies posted by firms in each country depends on the average characteristics of the workers searching inside that country. Wages are determined in an individual Nash bargain. We show the existence of multiple steady-state equilibria: one no-migration equilibrium and two migration equilibria. The multiplicity of equilibria is due to a self-fulfilling prophecy phenomenon linking average wages and incentives to migrate. The equilibria are Pareto-ranked, with migration-equilibria dominating no-migration.     

House Money Effects in Public Good Experiments

Are decisions in economics experiments distorted because the money subjects risk comes from the experimenter rather than their own pockets? There is some evidence that people receiving small, one time “windfall gains” have a higher marginal propensity to consume them, and when doing so, exhibit greater risk-seeking behaviour. This has been found in individual decision making experiments when anticipated wealth effects have been controlled, and labelled the “house money effect.” In public good experiments, house money effects could be driving the high levels of voluntary contributions commonly observed. This possibility is tested by comparing VCM contribution rates when subjects supply their own endowments with those when endowments are provided, while holding constant the distribution of promised earnings. No evidence of house money effects is found, suggesting that use of “free” initial money endowments does not distort subsequent contributions in VCM environments.     

Framing and Misperception in Public Good Experiments

Earlier studies have found that framing has a substantial impact on the degree of cooperation observed in public good experiments. We show that the way the public good game is framed affects misperceptions about the incentives of the game. Moreover, we show that such framing‐induced differences in misperceptions are linked to the framing effect on subjects' cooperation behavior. When we do not control for the different levels of misperceptions between frames, we observe a significant framing effect on subjects' cooperation preferences. However, this framing effect becomes insignificant once we remove subjects who misperceive.
