Opacity in bargaining over public good provision

We consider ultimatum bargaining over the provision of a public good. Offer-maker and responder can delegate their decisions to agents whose actual decision rules are opaque. We show that the responder will benefit from strategic opacity, even with bilateral delegation. The incomplete information created by strategic opacity choices does not lead to inefficient negotiation failure in equilibrium. Inefficiencies arise from an inefficient provision level. While an agreement will always be reached, the public good provision will fall short of the socially desirable level. Compared with unilateral delegation, bilateral delegation is never worse from a welfare perspective.     

Financial Control of a Competitive Economy with Public Goods but Without Randomness

The monetary and fiscal control of a simple economy without outside randomness is studied here from the microeconomic basis of a strategic market game. The government’s bureaucracy is treated as a public good that provides services at a cost. A conventional public good is also considered.     

Bargaining over Public Goods

In a simple public good economy, we propose a natural bargaining procedure, the equilibria of which converge to Lindahl allocations as the cost of bargaining vanishes. The procedure splits the decision over the allocation in a decision about personalized prices and a decision about output levels for the public good. Since this procedure does not assume price-taking behavior, it provides a strategic foundation for the personalized taxes inherent in the Lindahl solution to the public goods problem.     

Dynamic Games of Environmental Policy in a Global Economy: Taxes versus Quotas

The effects of environmental policy on the global environment as an international public good with a stock externality and national welfare are examined in a model with trade in a polluting commodity. The welfare effects of environmental policy, decomposed into terms of trade, abatement cost, and environmental damage effects, induce governments to adopt a strategic use of their policy measures. In the absence of international cooperation on environmental policy, it is demonstrated that the emission tax game brings about larger strategic distortions than the emission quota game.     

One-sided provision of a public good through bargaining under representative democracy

We examine a trade-off between strategic delegation and the internalization of interregional externalities through bargaining in the context of political economy. We show that in the case of one-sided provision of a public good, if the public good produced by one region generates a sufficiently significant spillover to another region, then interregional negotiation increases the total surplus of the entire economy.     

Nonprofits and public good provision: A contest based on compromises

Two competing nonprofits with ideologically distinct missions compete for donor funding to provide an indivisible public good in a population with heterogeneous preferences. This paper examines the extent to which (average) public values are undermined and nonprofits’ ideology compromised in a contractual game in which the right to provide the public good is the outcome of competition between nonprofits. We also scrutinize the roles of (i) cooperative versus competitive contracting, (ii) multiple public goods, (iii) enforceability of actions and (iv) observability of nonprofit costs in determining the equilibrium terms of the contract. In each case, the intensity of the ideological divide between the donor and the nonprofits jointly impact the degree to which compromises are made in terms of both the public's and nonprofit's missions, and the ability on the part of the donor to reap double (cost-saving and strategic) financial gains.     

Successful Leadership in Global Public Good Provision: Incorporating Behavioural Approaches

In the standard model of voluntary public good provision and other game theoretic models, climate-friendly leadership of a country is not successful: A unilateral increase of this country’s greenhouse gas abatement measures, i.e., contributions to the global public good of climate protection, will not lead to a positive reaction by the other countries but instead trigger a reduction of their abatement efforts and thus a crowding-out effect. In this paper it is shown how this undesired consequence need no longer occur when elements of behavioral economics are incorporated in the otherwise standard model of public good provision. In particular, strategic complementarities between the public good contribution of the leading country and those of the follower may result either if the follower has specific non-egoistic or other-regarding preferences or if the leader’s contribution positively affects the follower’s beliefs, i.e., his conjectural variations, about the leader’s behaviour.     

Strategic Complements, Substitutes, and Ambiguity: The Implications for Public Goods

We examine the effect of ambiguity in symmetric games with aggregate externalities. We find that ambiguity will increase/decrease the equilibrium strategy in games with strategic complements/substitutes and positive externalities. These effects are reversed in games with negative externalities. We consider some economic applications of these results to Cournot oligopoly, bargaining, macroeconomic coordination, and voluntary donations to a public good. In particular we show that ambiguity may reduce free-riding. Comparative statics analysis shows that increases in uncertainty will increase donations, to a public good.

Heterogeneity,impatience, and dynamic private provision of a discrete public good

We analyze dynamic private provision of a discrete public good by heterogeneous agents, who differ in terms of their levels of impatience, in a differential game framework. In contrast to the strategic complementarity result for homogeneous individuals, we show that an asymmetric completion Markov perfect equilibrium exists, where the individual contributions and the strategic behaviors depend crucially on an impatience differential: the difference in rates of time preference across groups of individuals. When this differential is insignificant, contributions of both types of individuals are strategic complements. On the other hand, when this impatience differential exceeds a threshold, the contributions of impatient individuals become strategic substitutes, whereas the contributions of patient individuals remain strategic complements. We show that group size has an interesting role to play in the strategic behavior: increasing the number of patient individuals aggravates the incentives to free‐ride by the impatient agents. We also derive a condition under which all the socially beneficial projects get completed in the equilibrium.     

Tax Competition, Capital Mobility, and Public Good Provision Within a Trading Block

The authors examine a two–country general–equilibrium model of a two–country trading block where governments through tax policies attract mobile capital and provide an imported public consumption good. Within this framework the authors examine, among other things, how preferences over the public good and the size (population) of a country affect the Nash or cooperative equilibrium values of income tax rates in the two countries. The analysis identifies sufficient conditions under which (i) the Nash/cooperative equilibrium income tax rates are strategic substitutes or complements, and (ii) the Nash equilibrium income tax rates may be greater than the cooperative rates.     

Group size and the private supply of a best-shot public good

This paper examines the relationship between group size and the likelihood that a best-shot public good is voluntarily provided. Holding fixed each member's individual probability of supplying the public good, the likelihood of supply increases as the group grows. This is the size effect. However, as group size increases, the probability that each individual member supplies decreases. This is the strategic effect. The net effect of group size on the likelihood is thus ambiguous. As group size increases without bounds, the two effects are offset—the likelihood approaches a finite limit.     

Global environmental problems and the strategic choice of technology

Reductions of environmentally harmful emissions are often a public good in a global context. For strategic reasons, countries may adopt a technology with high per unit cost of emission reduction, even if a technology with lower per unit cost is available at no extra cost. They thereby credibly commit themselves to not reducing emission much in the future. In a game of private voluntary provision of emission reduction, this commitment will make other countries increase their emission reductions. Also, in the case where countries cooperate in the future, such commitment gives a country a strategic advantage, because it shifts the disagreement point in a favorable direction.     

Elderly Care and Intrafamily Resource Allocation when Children Migrate

This paper considers the intrafamily allocation of elderly care in the context of international migration where migrant children may be able to provide financial assistance to their parents, but are unable to offer physical care. To investigate the interaction between siblings, I take a non-cooperative view of family decision-making and estimate best response functions for individual physical and financial contributions as a function of siblings' contributions. I address the endogeneity of siblings' contributions and individual migration decisions by using siblings' characteristics as instrumental variables as well as models including family fixed effects. For both migrants and non-migrants, I find evidence that financial contributions function as strategic complements while siblings' time contributions operate as strategic substitutes. This suggests that children's contributions toward elderly care may be based on both strategic bequest and public good motivations.     

Improving Voluntary Public Good Provision Through a Non-governmental,Endogenous Matching Mechanism: Experimental Evidence

Social norms can help to foster cooperation and to overcome the free-rider problem in the private provision of public goods. This paper focuses on the endogenous establishment of an average-oriented norm which sanctions deviations from average public good contributions. In a laboratory experiment, we analyse whether subjects are willing to implement a punishment and reward scheme at their own expense by applying the theory of non-governmental norm enforcement put forward by Buchholz et al. (J Public Econ Theory 16(6):899–916, 2014). Based on their theory, which omits a central authority but introduces an endogenously determined enforcement mechanism, we implement a two-stage public good game. In the first stage, subjects determine the strength of the sanctioning mechanism on their own. In the second stage, they decide on their personal contributions to the public good based on the established mechanism. In line with comparable pool punishment experiments, we find that subjects are apparently willing to contribute funds in order to establish a norm enforcement mechanism. Groups over-invest in the mechanism, but this over-investment decreases over time. These investments seem to be driven by the subjects’ previous individual contributions and partly by a number of strategic considerations, i.e. the previous average contribution made to the public good lowers the investment in the sanctioning mechanism. In the second stage of our experiment, higher norm enforcement parameters tend to lead to higher public good contributions. The earnings with the mechanism are on average higher than without.

Punishment and counter-punishment in public good games: Can we really govern ourselves?

A number of experimental studies have shown that the opportunity to punish anti-social behavior increases cooperation levels when agents face a social dilemma. Using a public good experiment, I show that in the presence of counter-punishment opportunities cooperators are less willing to punish free riders. As a result, cooperation breaks down and groups have lower earnings in comparison to a treatment without punishments where free riding is predominant. Approximately one quarter of all punishments are retaliated. Counter-punishments appear to be driven partly by strategic considerations and partly by a desire to reciprocate punishments.

A Public Choice Approach to Strategic and Nonstrategic Environmental Policy

In this paper we take a public choice perspective on strategic environmental policy and international environmental agreements. We examine cooperative and noncooperative environmental policies under governments that are either welfare maximizers (“good dictators”) or tax revenue maximizers (“Leviathans”). We show that Leviathans can perform better in terms of welfare and that good dictators can set higher taxes. We then analyze international environmental agreements and show that the breakdown of environmental cooperation can indeed lead to a welfare gain for all signatory countries. Considering a delegation game between governments, we find that a Pareto‐superior Leviathan outcome can be the unique Nash equilibrium.     

Adaptation to Climate Change: Commitment and Timing Issues

We study the impact of timing and commitment on adaptation and mitigation policies in the context of international environmental problems. Adaptation policies present the characteristics of a private good and may require a prior investment, while mitigation policies produce a public good. In a stylized model, we evaluate the impact of strategic commitment and leadership considerations when countries with different attitudes towards environmental cooperation coexist. We obtain equilibrium abatement and adaptation levels and environmental costs under partial cooperation for various timing and leadership scenarios. Crucially, global environmental costs suffered by countries are found to be greater when adaptation measures can be used strategically.     

Herding with collective preferences

This paper studies a simple model of observational learning where agents care not only about the information of others but also about their actions. We show that despite complex strategic considerations that arise from forward-looking incentives, herd behavior can arise in equilibrium. The model encompasses applications such as sequential elections, public good contributions, and leadership charitable giving.
