Weakest-link public goods: Giving in-kind or transferring money

This paper extends the analysis of weakest-link public goods, whose level equals the smallest of the agents’ provision levels, by permitting an agent either to increase one's own provision or else augment both one's own provision and that of the other agent(s). Nash equilibria may be either symmetric with agents matching one another's provision or else asymmetric with an in-kind transfer by one agent to another. An equilibrium with cash transfers, but no in-kind transfers, may be Pareto superior to one with only in-kind transfers. If agents differ in their efficiency, then in-kind transfers by the low-cost agent may dominate a cash transfer. The possibility of Pareto-improving transfers is enhanced as the number of agents increases.     

Multinational public goods provision under multilateral income transfers and productivity differences

This article examines multinational public goods provision under multilateral income transfers and productivity differences across countries. Under a planner who uses linear approximation for utility maximization, we show that (1) a country is an income receiver if it has a higher productivity than the average in producing public goods, enabling it to provide more public goods; (2) the amount of transfers can be pinned down for all countries with an adjustment cost; (3) each country obtains an identical utility increment; and (4) the country with the lowest adjustment cost is the best candidate for the planner country. All results are derived based on well-known information regarding the cost of producing the public goods and income levels.     

Consumption externalities and the effects of international income transfers on the global environment

In this paper, we extend the standard model of private provision of public goods by including consumption externalities to characterize a situation in which economic activities pollute the environment. We consider a case in which there are an industrial country which can afford to invest in the environment and a developing country which cannot. Then, we show that international income transfers in both directions can improve the global environmental quality as well as the welfare of each country. We also show that the results have important implications for policies such as official development assistance or the assignment of tradable emission permits.     

Effects of Technology Transfers on the Provision of Public Goods

In this paper, we examine the viability ofcooperative policies oriented to the resolution oftransboundary pollution problems using the theory ofprivate provision of public goods in a two-countrymodel. We analyze the effects on economic welfare ofvoluntary technological transfers oriented to reducingthe emission of pollutants.Our analysis shows that when the atmosphere istaken as a pure public goods, ``a strong paradox' emerges:the advanced country, in spite of the transfer, seesits economic welfare improved while the developingcountry sees it worsen. Moreover, if both a technicaland an income transfer occur, this paradox mightnot be solved. Furthermore, ``a paradoxicalimprovement' occurs when the advanced country does nottake any policy towards the environment but thedeveloping country does: an improvement in the levelof technology in the developing country allows for anexpansion of the level of utility in both countries.On the other hand, in the case where the atmosphere istaken as an impure public goods, when both countriespursue an abatement policy, the transfer of technologyleads to an improvement in welfare in bothcountries.     

Nature of transfers,income tax function and empirical estimation of elasticity of taxable income for Brazil

This article aims to estimate the elasticity of taxable income (ETI), taking into account the nature of transfers and their use as a redistribution package (involving cash and in-kind transfers) to households in Brazil. Our contributions are twofold. First, we provide a simple model with balanced-budget government that reveals the role played by cash and in-kind transfers on the labour supply (and income tax revenues thereof). Next, in order to estimate ETI in the presence of cash and in-kind transfers, Brazilian population surveys (Pesquisa Nacional por Amostra de Domicílios [PNAD]) are used to explore a limited tax reform that was implemented between 1997 and 1998. This reform only affected the higher income tax bracket. Our findings suggest that in-kind (cash) transfers are positively (negatively) associated with reported taxable income and precise estimation of ETI requires estimates of both types of transfers. Last, we estimate the ETI for Brazil in the range from 0.4 to 1.3 not different from those that maximize income tax revenues.     

Social Insurance with In-kind Provision of Private Goods

This paper addresses the desirability of providing in-kind transfers as a screening device to facilitate redistribution of income from able to disabled persons within a social insurance system. An optimal policy—consisting of cash transfers, income-contingent in-kind transfers of one good particularly demanded by disabled workers, and linear taxation of other commodities—is characterized. It is then asked whether and, if so, when this policy can be replaced by an "earning-tested scheme" that provides the in-kind good only to those indivi duals who have no earnings from labor or by a non-linear pricing policy.     

Heterogeneous preferences and in-kind redistribution: Theory and evidence

This paper examines the impact of social heterogeneity on in-kind redistribution. We contribute to the previous literature in two ways: we consider (i) the provision of several public goods and (ii) agents different not only in income, but also in their preferences over the various goods provided by the public sector. In this setting, both the distribution and size of goods provision depend on the heterogeneity of preferences. Our main result is that preference heterogeneity tends to decrease in-kind redistribution, while income inequality tends to increase it. An empirical investigation based on United States Census Bureau data confirms these theoretical findings.     

A reinterpretation of the traditional income–leisure model,with application to in-kind subsidy programs

The traditional income–leisure model treats income as a composite commodity; it is not appropriate for studying commodity subsidies which alter relative prices within the composite. I suggest reinterpreting the traditional model as a special case of a utility function weakly separable with respect to leisure and all other commodities. This interpretation allows the work incentive effects of any subsidy program to be inferred from the terms of the program and data on the work effort effects of any other subsidy program, most notably income maintenance experiments. I illustrate the approach by estimating the work incentive effects of public housing. The model implies that even if special complementaries between leisure or work and the subsidized good are neglected, in-kind transfers will have different work incentive effects than equivalent cash transfers. In practice, in-kind transfers will generally stimulate work effort vis-à-vis equivalent cash grants.     

THE ECONOMIC WELFARE OF THE AGED AND INCOME SECURITY PROGRAMS*

This paper examines several nonmoney components of economic welfare in both a theoretical and an empirical framework, computes the distributional ranking of aged families arising from such a measure, and subsequently examines the target effectiveness of eleven programs of the U.S. federal government aimed at the aged. While the theoretical discussion attempts to cover all factors contributing to the economic welfare of the aged, the empirical measure is somewhat less comprehensive, excluding the value of nonmarket productive activities and leisure time as well as benefits derived from direct government expenditures and some in-kind transfers and taxes. The study makes use of a subsample of the 1967 Survey of Economic Opportunity data composed of all families with at least one aged member. Specific attention is devoted to dissaving from net worth, in-kind transfers, incidence of taxes, and intrafamily transfers. Government cash and in-kind transfers are found to constitute a third of the total measured economic welfare of the aged, and the impact of each of these programs is examined individually. As might be expected, public assistance and public housing are the programs of most benefit to the aged poor. Medicaid and Medicare are substantially less so, and Social Security is distributionally neutral. Such programs as unemployment insurance are of little benefit to the aged. Tax expenditures, finally, provide no benefits to even the lower half of the distribution.     

Why Free Trade May Hurt Developing Countries

This paper builds a general equilibrium trade model where a country produces two traded goods and one nontraded public consumption good. The government finances the provision of the public good by taxing the incomes of factors of production, and/or by imposing tariffs. Within this framework, the paper (i) shows that a small tariff or an income tax improves the country's welfare if there is an undersupply of public good, and (ii) identifies the circumstances in which an improvement in the country's terms of trade may reduce its welfare, and free trade can be inferior to autarky. A terms of trade improvement, or the movement from autarky to free trade, definitely improves the country's welfare if the government imposes a tariff that leaves the domestic relative price of the imported good unchanged.     

An Economic Analysis of Public Transfers

This paper develops simple models of public transfers. The sources of income inequality are differences in ability and in luck. The government employs a redistribution policy that arises from altruistic motives in the case of ability differences. I consider the case where the government re-optimizes income transfers after it observes the outcome of private activities. When the source of income inequality is differences in luck, the economy creates a mutual insurance or provides public goods out of risk-sharing motives. I derive the paradoxical result that a more able individual would not enjoy higher welfare than a less able individual. I also investigate how public transfers react to increases in income level and income inequality.

Free‐Riding and the Provision of Public Goods in the Family: A Laboratory Experiment*

We examine the provision of family public goods using experimental economics methods. With sufficient altruism and shared resource arrangements, families can provide the efficient level of family public goods. Becker's Rotten Kid Theorem asserts that transfers from altruistic parents will induce children to maximize family income even if children are not altruistic toward other family members. Consistent with altruism, parents and children contributed more to a public good when in groups with family members than when in groups with strangers. In contrast to the predictions of the Rotten Kid Theorem, however, children's behavior fell short of maximizing family income.     

Public Good Provision and Ancillary Benefits: The Case of Climate Agreements

Several studies found ancillary benefits of the provision of public goods to be of considerable size. If these additional private benefits were noticed, they would imply not only higher cooperative but also non-cooperative provision levels. However, beyond these largely undisputed important quantitative effects, there would be qualitative and strategic implications associated with ancillary benefits: public policy would no longer be a pure but an impure public good. In this paper, we investigate these implications in a setting of non-cooperative coalition formation in the context of climate change. In particular, we address the following question. Would ancillary benefits if they were taken in consideration increase participation in international climate agreements and raise the success of these treaties in welfare terms?     

Welfare Effects of Different Public Expenditures and Taxes in the Netherlands

This paper explores the welfare effects of public consumption, income transfers and public investment financed through different types of taxes. One surprising result is that, contrary to public consumption goods, public capital goods do not necessarily become less attractive if distortionary taxes, rather than lump-sum taxes, are necessary to finance them. The numerical simulations reveal that the net welfare effects of public investments in the Netherlands are typically positive if financed through lump-sum taxes or distortionary taxes on labor. However, if a source-based capital tax is adopted to finance public investments, the overall welfare effect may be negative.     

Relative consumption and majority voting: supplementing Oates’ “Decentralization Theorem”

This paper reconsiders the question of whether centralized or decentralized provision of local public goods is preferable, taking into account two new elements: the appearance of relative consumption effects and the possibility of an inefficient election outcome due to a right-skewed income distribution. Surprisingly, our results indicate that (1) decentralization may lead to a strictly higher welfare level than centralization, even if regions are homogeneous, and (2) under certain circumstances centralization may be welfare superior, even though traditional public good spillovers are not considered in our framework. Whether centralization or decentralization is preferable crucially depends on the extent to which social interaction takes place between regions.     

MEASURING THE BENEFITS FROM PUBLIC SERVICES: THE EFFECTS OF LOCAL GOVERNMENT SPENDING ON THE DISTRIBUTION OF INCOME IN NORWAY

The purpose of this paper is to provide an evaluation of how local public in-kind benefits affect the distribution of income in Norway. To this end, a method that accounts for differences between municipalities in capacity to produce the same standard of public services is used for assessing the value of sector-specific local public services in each municipality. Moreover, recipient frequencies in various demographic groups are used as basis for determining the allocation of the assessed value of services on citizens of the municipalities. The empirical results show that inequality in the (marginal) distribution of municipal in-kind benefits is rather high. The contribution of municipal in-kind benefits to inequality in the distribution of extended income (cash (after-tax) income plus municipal in-kind benefits) proves, however, to be approximately neutral.     

Equality of opportunity and optimal cash and in-kind policies

This paper examines the argument for public provision of certain private goods, like education and health, based on equality of opportunity by studying the utility possibility frontier of a society in which there is a concern for the distribution of these goods. A given quality of education or health services can be consumed for free in the public sector, but people can opt-out and purchase their desired quality levels in the private sector. Some of the conclusions are: (i) a pure cash transfer is optimal when the utility redistribution is either “sufficiently” small or large; (ii) if and only if both the equality-of-opportunity concern and the utility redistribution are large enough, can an in-kind program which attracts the whole population be justified; (iii) even when everybody chooses the in-kind program, it may be optimal to perform some additional utility redistribution by increasing the size of such program.     

Motives for household private transfers in Burkina Faso

Resource transfers among households have received considerable interest among economists in recent years. Two of the main reasons for the surge of interest in household transfers are the information on human nature conveyed by transfer behavior and the implication on income redistribution policy that private transfer might have. Empirical studies, however, provide mixed results on transfer behavior. This is because previous inquiries were confronted with several estimation issues and have focused on data from developed countries where private transfers are already small. This paper contributes to the literature on transfer behavior by using a multifaceted econometric approach to examine the motives of household transfers in Burkina, a low-income country with a well-documented tradition of gift exchanges. The findings suggest that risk sharing is not central to transfers. Altruistic transfers are apparent for the middle income class, but not at low income level. The evidence implies that crowding out may be minimal at low income level, suggesting that public transfers targeting poor households may be effective.     

Capital income taxation,tax criteria,and intergenerational welfare

In a two-period overlapping-generations model, residence criteria are shown to be optimal with lump-sum transfers to the younger generation in a dynamically efficient open economy even if all wage income, corresponding to rent income under exogenous labor supply, is not taxed away. When tax revenues are also distributed to the older generation — which indeed may be desirable for short-term intergenerational welfare distribution reasons — a weighted average rule is derived for optimal international taxation. The taxation of domestic savings income follows the inverse elasticity rule in respect to savings and, surprisingly, higher investment elasticity increases the tax level. Finally, for a small open economy and for large identical economies, tax competition with a mixed scheme of residence-based taxes and source-based subsidies yields the same tax policy as tax cooperation with no restrictions on the domestic and international capital income tax instruments.
