A generalized impure public good and linear characteristics model of green consumption

This paper provides a general framework for understanding consumer behavior related to goods and services that may be considered environmentally friendly, ethically produced, fairly traded, or some combination thereof. We generalize the impure public good model and derive its comparative static properties. The model accounts for any number of impure public (green) goods and joint production of any number of both private and public characteristics. The generalization provides a bridge between the impure public good model and the well-known linear characteristics model, both of which are special cases of the model developed here. The results show how demand for green goods and characteristics such as environmental quality depends on wealth, exogenously given levels of public goods, and the technologies of joint production. The effects of changes in technology depend critically on whether jointly produced characteristics are complements or substitutes in consumption. Several of the results are rather counterintuitive and differ in meaningful ways from existing models of impure public goods and linear characteristics. The results also illuminate several reasons for greater caution about whether it is reasonable to assume that green goods and services are necessarily beneficial for the provision of public goods.     

Demand for Environmental Quality: An Empirical Analysis of Consumer Behavior in Sweden

In this paper we estimate the income elasticity of demand for recreational services and other traditional groups of goods in Sweden and test for potential changes in such estimates over the twentieth century. Due to the difficulty of directly observing the demand for recreational services, we employ an indirect methodology by using the demand for some outdoor goods as a proxy for the demand for recreational services. In line with most prior research, our results confirm the expectation that recreational services, as a public good, is a luxury good in Sweden. Our results also show that the income elasticities for traditional goods are stable over time, indicating that consumer preferences for expenditure on these specific commodities do not change over time.      

Public consumer goods, output-generated variable returns, and labor supply

This paper develops a simple general-equilibrium model of a closed economy. The economy under consideration produces two final goods, one private and one public, which are both produced with labor and an intermediate good under constant returns to scale. The intermediate good is produced by labor alone, and its production is subject to output-generated variable returns to scale. The public good can be interpreted as government spending on environmental quality, police protection, cultural activities, and publicly funded health care. The model is used to examine the impact of an exogenous change in labor supply on the size of the government, relative prices, and welfare. Within the context of the present study, an increase in labor supply can be attributed to either exogenous immigration or population growth. The model is also used to examine the relationship between the size of the country and the pattern of trade.     

A STABLE NASH MECHANISM FOR QUASI-ADDITIVE PUBLIC-GOOD ENVIRONMENTS*

In this paper we present a simple game form implementing Lindahl allocations as Nash equilibrium outcomes, which has nice stability properties. we show that if the preferences of eaach consumer are representable by a utility function of the form a(y)x_i+b_i(y), where x_i(y), where x_i is the amount of private good and y, the amount of public good, then the Nash equilibrium of our geme is locally stable under the gradient adjustment process. This restriction on the preferences has been known in hte literature as the necessary and sufficient condition for the Pareto optimal amount of pukic goods to be independent of the private goods distribution. This type of preference includes quasi-linear preferences as a special case. but unlike quasi-linearity, this allows a non zero income effect of demand for public goods as well as private goods, which is often supported by empirical evidence. Our result shows how an equilbirium can be achieved over time by a decentralized strategy adjustement process for a fairly general class of environments, even in the absence of a dominant-strategy equilibrium.     

Individual incentives in the supply of public inputs

The free-rider hypothesis states that, in the decision on public-goods and private-good provision, individual incentives are such that public goods will tend to be undersupplied. This paper examines the free-rider argument as it applies to public intermediate goods. It is shown that, unlike in a static model, in a dynamic world there may exist incentives for firms to act cooperatively in determining the supply of public intermediate goods. In a dynamic context there is a cost to free riding: what one firm does now affects what others will do in the future. Provided future profits are not discounted too heavily, the free-rider problem may disappear when a time dimension is added to the theory.

分税制改革、地方财政自主权与公共品供给

本文发现20世纪90年代中期以来中国地方公共品供给水平有下降趋势,同时发现较高的公共品供给水平总是和较高的地方财政自主权联系在一起.本文应用分省面板数据,特别利用了1994年分税制改革导致的地方财政自主权的跨时和跨区变化,为上述假设提供了实证证据.本文认为中国在财政分权化过程中面临的一系列既有制度设置可以作为上述因果关系的解释机制.一系列测量偏误和模型选择的检验显示本文的实证结论是稳健的.基于中国的研究支持了那些认为财政分权而不是集权将改善地方公共品供给水平的观点.     

Intraindustry trade in intermediate goods

Since intermediate goods play such a vital role in foreign trade, this paper develops a model that explains the benefits from intraindustry trade in differentiated intermediate goods. In comparison with a situation of autarchy, this type of trade causes an increase in the number of intermediate good varieties. In this way, the producers of final goods will benefit from intermediate good varieties, which are closer to the ideal for a specific production process. At the same time, the producers of intermediate goods will, under conditions of international division of labor, benefit from economies of scale.     

Skilled–unskilled wage inequality,product variety,public input and increasing returns: A static general equilibrium analysis

The paper develops a four sector small open economy model with two traded final good sectors, a public intermediate good producing sector and a nontraded good sector producing varieties of intermediate goods. There are three primary factors: capital, skilled labour and unskilled labour. Industrial sector producing a traded good uses capital, intermediate goods and skilled labour as inputs. Intermediate goods producing sector also uses capital and skilled labour. Public input producing sector and the agricultural sector producing the other traded good use capital and unskilled labour as inputs. It is shown that, if production technologies are the same for the agricultural sector and the public input producing sector and if the scale elasticity of output is very low, then an increase in capital stock (unskilled labour endowment) raises (lowers) the skilled–unskilled wage ratio. However, an increase in skilled labour endowment does not produce any unambiguous effect. On the other hand, an increase in the tax rate on industrial output and/or an increase in the price of the agricultural product, armed with the same set of assumptions, lowers the skilled–unskilled wage ratio.     

Public provisions of professional services

Professional services are credence goods provided by certified experts (professionals). The most prominent examples of professional services are medical or legal services. Interestingly, the markets for such services are often subject to partial public provision: there is a low-end segment, where the services of basic quality are provided for free and professionals are reimbursed by the government, and a high-end segment, where free-market principles prevail. We examine the efficiency of this market structure. To this end we apply a modified version of the model of the market for goods with credence attributes proposed by Baron. We demonstrate that partial public provision can correct for the market failure caused by the credence good nature of professional services, even in the presence of regulation costs. The efficiency gain from partial public provision is due to a combination of quality and price effects.     

The Provision of Language‐Specific Public Services

I consider the optimal provision of public services when individuals' effective consumption of the services depends on their proficiency in the language they are provided in. A social planner chooses levels of provision in both a dominant and minority language which are financed by a linear tax on labor income. Minority language speakers make a costly investment to increase their proficiency in the dominant language. In doing so they increase their wage and, possibly, gain access to higher levels of public services provided in the dominant language. The planner faces a trade‐off between compensating minority language speakers for their lower wages and encouraging their integration by rewarding higher levels of dominant language proficiency. Under majority voting, it is possible that the level of public services is increasing in the relative size of the minority language community. This result contrasts with what is typically assumed in the literature on fractionalization and public good provision—that cultural heterogeneity decreases the level of public goods.     

Public–private partnerships for the provision of public goods: Theory and an application to NGOs

When will a public good or service be provided by the government, when will it be provided by a NGO, and when will we see a private–public partnership? This paper provides a model where a typical public good requires different inputs which raises the possibility of partnerships to exploit comparative advantages of different parties. But hold-up problems due to contractual incompleteness in specifying tasks discourage separation of ownership and management. The fact that public goods have the property of non-rivalry and non-excludability and that NGOs tend to be non-profits drives our key results. We apply the framework to NGOs in developing countries which, in the last few decades, have been increasingly involved in various capacities in the provision of a wide range of public goods and services.     

Public goods, merit goods, and the relation between private and government consumption

In this paper, we investigate the relation between public and private consumption, by constructing a general government spending data set, by function, for 12 European countries. In particular, we split government consumption into two categories. The first category—“public goods”—includes defence, public order, and justice. The second category—“merit goods”—includes health, education, and other services that could have been provided privately. Equations from a relatively general permanent income model are estimated by GMM. The estimates are fairly robust in showing that public goods substitute while merit goods complement private consumption. However, the relation between merit goods and private goods turns out to be stronger than that between public goods and private goods. Thus, in the aggregate government and private consumption are complements.     

International Factor Mobility, Government Size and Welfare

An examination of the available data reveals that the size of government varies considerably across time and countries. By making use of a simple general equilibrium model, this paper demonstrates that size of government is affected by the availability of capital and labour within an economy. Specifically, this paper utilises a model of a closed economy that produces one-private and one-public good. Both goods are produced by means of capital and labour. Production functions are subject to constant returns to scale and perfect competition prevails in all markets. The elasticity of substitution between the public and the private good is greater than unity and there is no international factor mobility in the initial equilibrium. The size of government is measured by total spending on the public good as a proportion of the total expenditure on the private and public goods. It is shown that capital (labour) inflow can decrease (increase) the size of government. Capital inflow increases welfare if the private good is relatively capital intensive whereas labour inflow increases welfare if the public good is relatively capital intensive.     

Reliability of individual valuations of public and private goods: Choice consistency, response time, and preference refinement

We examined the reliability of a large set of paired comparison value judgments involving public goods, private goods, and sums of money. As respondents progressed through a random sequence of paired choices they were each given, their response time decreased and they became more consistent, apparently fine-tuning their responses, suggesting that respondents tend to begin a hypothetical value exercise with relatively imprecise preferences and that experience in expressing preference helps reduce that imprecision. Reliability was greater for private than for public good choices, and greater for choices between a good and a monetary amount than for choices between two goods. However, the reliability for public good choices was only slightly lower than for the private goods.     

Property values,local public expenditure and economic efficiency

A bid-rent model of property value determination with a public good and property taxation is developed. Using the local government budget constraint, an estimating equation is derived which can indicate whether public goods are efficiently provided. The empirical results show over-provision of public goods in northeastern New Jersey.     

Income Distribution, Taxation, and the Private Provision of Public Goods

This article investigates the role of taxation when public goods are privately provided. Externalities between consumers via the public good are shown to cause kinks in social indifference curves. As a result, a government restricted to income taxation should engineer enough inequality to ensure there are some non-contributors to the public good. Whether commodity taxation changes this conclusion depends on the extent to which consumers "see through" the government budget constraint. If they can, inequality should still be sought. When they cannot, in contrast to the case of an economy with only private goods, commodity taxation can be used in conjunction with income transfers to achieve the first-best.     

Tax instruments as constraints on the disposition of public revenues

This paper examines the possible selection of tax instruments as means of inducing a Leviathan-like government to provide the public goods and services that taxpayer-beneficiaries desire. The analysis is conducted in a constitutional setting, in which potential taxpayers-beneficiaries confront choices among tax instruments, when these are taken to be the primary constraints on the behavior of government in postconstitutional periods. The analysis suggests a particular form of earmarking; each expenditure is allotted a particular tax base that is highly complementary with the public good itself. The complementarity between tax base and the corresponding public good is the central relationship that exerts discipline on government. Arguments for this type of earmarking have not, to our knowledge, been previously developed in tax theory.
