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.     

Between-group contests over group-specific public goods with within-group fragmentation

We model a contest between two groups of equal sized populations over the division of a group-specific public good. Each group is fragmented into subgroups. Each subgroup allocates effort between production and contestation. Perfect coordination is assumed within subgroups, but subgroups cannot coordinate with one another. All subgroups choose effort allocations simultaneously. We find that the group that is more internally fragmented receives the smaller share of the public good. Aggregate rent-seeking increases when the dominant subgroups within both communities have larger population shares. Any unilateral increase in fragmentation within a group reduces conflict and increases the total income of its opponent. Strikingly, the fragmenting community itself may, however, increase its total income as well, even though its share of the public good declines. Hence, a smaller share of public good provisioning cannot be used to infer a negative income effect on the losing community.

Free riding with discrete and continuous public goods: Some experimental evidence

Two experimental designs were employed in which subjects were offered either a “discrete” public good, for which group contributions must meet a provision point before subjects receive payoffs; and a “continuous” public good, which returned 30 percent of group contributions to each subject at all contributions levels. Free riding, or non-contribution, is a dominant strategy in the continuous case. Non-contribution is not a dominant strategy in the discrete case; there are multiple equilibria. Contribution levels were similar in both cases, and did not vary significantly with method of payment (hypothetical versus real money); earnings, however, were higher in the continuous and realmoney versions of the experiment. Subjects' demographic characteristics made little difference to contribution patterns. The most significant determinant of contributions was the round of the “game.” Roughly speaking, subjects contributed less the longer they played, regardless of other factors.     

From weakest-link to best-shot: The voluntary provision of public goods

It has traditionally been assumed that the socially available amount X of a public good is the simple sum of the separate amounts x _i produced by the i = 1, ..., I members of the community. But there are many other possibilities of practical importance. Among them are: (i) Weakest-link rule, where the socially available amount is the minimum of the quantities individually provided, and (ii) Best-shot rule, where the socially available amount is the maximum of the individual quantities. The former tends to arise in linear situations, where each individual has a veto on the total to be provided (e.g., if each is responsible for one link of a chain); the latter tends to arise when there is a single prize of overwhelming importance for the community, with any individual's effort having a chance of securing the prize. In comparison with the standard Summation formula of ordinary public-good theory, it is shown that underprovision of the public good tends to considerably moderated when the Weakest-link function is applicable, but aggravated when the Best-shot function is applicable. In time of disaster, where the survival of the community may depend upon each person's doing his duty, the conditions for applicability of the Weakest-link rule are approximated. This circumstance explains the historical observation that disaster conditions tend to elicit an extraordinary amount of unselfish behavior.     

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.     

The voluntary provision of a pure public good with diminishing marginal returns

In experiments investigating the voluntary provision of a pure public good, participants consistently allocate resources to this good when the Nash prediction is to allocate nothing. This paper explores the robustness of this result when the Nash prediction calls for a division of resources between the private and public goods. We consider how a change in individual resource endowments and supplemental earnings information affect allocations to the public good. Results indicate that, under both the high and low endowment conditions, groups continue to allocate more resources than the Nash prediction. However, providing participants with detailed instructions that describe the declining marginal benefit to the public good leads to a significant decrease in allocations to the public good.     

The life satisfaction approach to valuing public goods: The case of terrorism

Terrorism has large social costs that are difficult to quantify for the well-known problems of eliciting people’s preferences for public goods. We use the LSA to assess these costs in utility and monetary terms. Based on combined cross-section time-series data, we estimate the costs of terrorism for France and the British Isles. We find large negative effects of terrorism on life satisfaction that translate into considerable compensating surpluses for a hypothetical reduction in terrorism, in particular for the serious conflict in Northern Ireland. The effects of terrorism are robust and differ across groups in accordance with prior expectations.
