Distortionary taxation and the free-rider problem

This paper derives a version of the Samuelson rule which takes into account that a distortionary Ramsey-tax system is used to finance public-goods provision. Individuals have private information about their public-goods preferences. Moreover, individuals differ in their productive abilities. The incidence of taxation in the Ramsey model implies that more productive individuals have a lower willingness to pay for public goods than less productive individuals. They are therefore tempted to understate their valuation of public goods and less productive individuals are inclined to exaggerate theirs. The paper characterizes an optimal rule for taxation and public-goods provision that eliminates these biases.     

A Second-Best Theory of Local Government Policy

This paper provides a model where a large number of small jurisdictions compete for mobile firms and households by supplying local public goods and factors. Jurisdictions only have an incomplete set of tax instruments at their disposal to achieve an efficient allocation. We derive second-best behavioral rules for local governments and extend optimal taxation results to the local level. Local governments distort locational decisions of mobile firms and households by taxing them above marginal congestion costs so as to balance relative locational distortions between taxes. The analysis also reveals that there is a systematic difference between the provision of local public goods and factors. While local public goods are provided according to the Samuelson rule in most situations considered, local public factors are undersupplied relative to this rule.     

信号消费、异质消费与公共产品自愿供给

传统的经典理论分析了政府供给公共产品和消费者无差别消费时的经济问题。然而在市场经济中消费者的类型是不相同的,对公共产品的消费需求也各不相同。对此,需要研究不同消费需求、不同供给模式下具有"消费信号"的公共产品自愿供给问题。研究发现,提高公共产品消费的信号性,优化公共产品的供给模式对于公共产品的自愿供给非常重要。同时,识别出"信号消费"下的异质消费者,并使公共产品具有私人产品的消费特征时,公共产品自愿供给的意愿将会增加。     

Self‐Insurance and Self‐Protection as Public Goods

Many public goods provide utility by insuring against hazardous events. Those public goods can have self‐insurance and self‐protection character. For both situations we analyze the efficient public provision level and the provision level resulting from Nash behavior in a private provision game. We consider the interaction of public goods as insurance devices with market insurance. The availability of market insurance reduces the provision level of the public good for both public and private provision, regardless of whether we consider self‐insurance or self‐protection. Moreover, we show that Nash behavior has always a larger impact than the availability of market insurance.     

The marginal cost of public funds is one at the optimal tax system

This paper develops a Mirrlees framework with skill and preference heterogeneity to analyze optimal linear and nonlinear redistributive taxes, optimal provision of public goods, and the marginal cost of public funds (MCF). It is shown that the MCF equals one at the optimal tax system, for both lump-sum and distortionary taxes, for linear and nonlinear taxes, and for both income and consumption taxes. By allowing for redistributional concerns, the marginal excess burden of distortionary taxes is shown to be equal to the marginal distributional gain at the optimal tax system. Consequently, the modified Samuelson rule should not be corrected for the marginal cost of public funds. Outside the optimum, the marginal cost of public funds for distortionary taxes can be either smaller or larger than one. The findings of this paper have potentially important implications for applied tax policy and social cost–benefit analysis.

Financial Reporting BY Local Government And The Disproportionate Requirements Of AAS 27

This paper discusses the economic characteristics, and related financial reporting issues, of goods and services provided by local government. These goods are grouped into three categories: public, private, and mixed public/private goods and services. Modified cash-based reports are found to be proper for government units that provide public and mixed goods, and accrual-based accounting is appropriate for units that provide private goods. When the provision of mixed goods and services by local government is not mandatory, the disclosure of the market value of the assets employed in producing these goods or services is also warranted.     

Öffentliche Güter mit Versicherungscharakter

Dikes as well as early warning systems against natural disasters are just two examples for pure public goods that serve as an insurance device. Dikes reduce the probability of a loss caused by flooding. Such public goods can be seen as public self-protection. By contrast, early warning systems do not reduce the probability of a loss, but the size of a loss. Hence, such public goods can be seen as public self-insurance. The present paper presents a model which takes these characteristics into account. Conditions for the efficient provision of such public goods are derived. Moreover, we analyze the consequences of a change in income and risk aversion towards the efficient provision level as well as the interaction with private market insurance.     

Taxation, Migration, and Pollution

This paper analyzes optimal fiscal, environmental and immigration policy for a single jurisdiction. In the presence of immigration quotas, taxes on the output of externality-producing industries should be higher than indicated by the standard rule for Pigovian corrective taxation. Immigration quotas are not optimal if fiscal instruments can be used to control immigration, and relaxation of immigration quotas generally increases domestic welfare. If optimal taxes are imposed on immigrants, no immigration quota should be imposed, and a version of the traditional Pigovian rule characterizes optimal taxation of domestic externalities. If production in the immigrants' country of origin causes trans-boundary spillovers, domestic welfare can be improved by lighter taxation of immigrants or by further relaxation of immigration quotas.

Global and Regional Public Goods: A Prognosis for Collective Action

This paper applies modern concepts from the theory of public goods to indicate why progress has been made with respect to some global and regional public goods (for example, cutting sulphur emissions) but not with respect to others (for example, cutting greenhouse gases). Factors promoting collective action at the transnational level include the removal of uncertainty, a high share of nation-specific benefits, a limited number of essential participants and the presence of an influential leader nation. The impact of public good aggregation technologies on the future provision of transnational public goods is related to the trend in world-wide income inequality. Principles are presented for designing supranational structures for addressing transnational public good problems. JEL classification: H41, D70, Q20.     

A public good model with lotteries in large groups

We analyze the effect of a large group on a public goods model with lotteries. We show that as populations get large, and with preferences in which people only care about their private consumptions and the total supply of the public good, the level of contributions converges to the one given by voluntary contributions. With altruistic preferences of the warm-glow type, the contributions converge to a level strictly higher than those given by voluntary contributions, but in general they do not yield first-best levels. Our results are important to clarify why in general governments do not rely on lotteries for a large part of the revenue creation for public good provision. They are also useful to understand why lottery proceeds are earmarked to worthy causes, where warm glow is likely to be larger.     

Protecting the Vulnerable: the Tradeoff between Risk Reduction and Public Insurance

In a risky world should governments provide public goods thatreduce risk or compensate the victims of bad outcomes throughsocial insurance? This article examines a basic question indesigning social protection policies: how should a governmentallocate a fixed budget between these two activities? In thepresence of income and risk heterogeneities a simple publicinsurance scheme that pays a fixed benefit to all householdsthat suffer a negative shock is an effective redistributionalinstrument of public policy. This is true even when a well functioningprivate insurance market exists, and so the role of public insuranceis not to correct a market failure. In fact, the existence ofa private insurance market means that the public system hasdesirable targeting properties—all but the poor and high-risktake up private insurance. The provision of public goods thatreduce risk for all should therefore be complemented with publicinsurance that (automatically) benefits those who are especiallyvulnerable.     

我国开征不动产税与增强地方政府公共服务能力的思考

在物质生活基本得到满足的情况下．老百姓对医疗、教育、社会保障、公共安全以及环境保护等公共产品和公共服务的需求越来越突出，对地方政府的目标要求也不再是发展经济这一单一目标，而是更加强调其公共服务的能力。地方政府的公共服务能力在很大程度上取决于其收入能力。本文将探讨不动产税改革将如何在增强地方政府公共服务能力中发挥作用，并针对开征不动产税过程可能遇到的难点问题，提出相关对策建议。     

行政区划壁垒、边界地区公共品提供与经济发展

行政区划壁垒是阻碍区域协调发展的重要因素。本文首先分析了行政区划壁垒对省际交界地带经济发展可能产生的两种效应——边界跳跃效应和边界洼地效应,接着利用栅格级别夜间灯光亮度和公共品提供数据,对两种效应进行检验。结果显示:第一,省际交界地带不存在显著的边界跳跃效应,紧邻省界两侧的地带在经济发展和公共品提供水平上都高度接近;第二,省际交界地带存在明显的边界洼地效应,越靠近省界的地区,经济发展和公共品提供水平越滞后,这一效应在距离省界20公里的范围内尤为明显。边界洼地效应的存在导致省内核心地带的经济发展难以辐射到边界地带,也可以作为边界跳跃效应不存在的原因。本文研究表明,进一步打破传统的以行政区划为界线的分割式治理体系,不仅有助于促进区域协调与平衡发展,也有助于畅通国内大循环、构建新发展格局。     

A Trusteeship Theory of Accounting for Natural Capital Assets

One of the problems encountered in implementing accrual accounting in the government sector is that of accounting for natural capital assets provided freely to government and which are used as public goods. Professional accounting standards require that these assets be valued and included in the government's statement of assets and liabilities. The problem is not encountered in business accrual accounting because business neither acquires assets freely nor provides services to the public on a non-commercial basis.
Various issues surrounding accrual accounting for natural capital assets used as public goods are examined in this article. The nature and characteristics of such assets, and the distinctions between private goods and public goods markets, are first explained to set the context for examination of the issues. Then the issues as to whether natural capital assets should be treated as assets for accounting purposes and included in the government's statement of financial position are analysed according to FASB standards; it is concluded that they are not assets. Rather, it is proposed that these assets used for the provision of non-commercial services to the public should be treated in a separate category as public goods assets which are held in trust by the government on behalf of the nation, for the benefit of current and future generations and for the preservation of the natural ecology of the nation. Commercial valuations are not relevant for these assets and they need not be valued in financial terms for their good management.     

交易费用、政府边界与财政体制改革

将新制度经济学中的交易费用理论引入政府供给公共产品的分析，给出了政府供给公共产品的边界的理论模型。我国政府在供给公共产品过程中发生的交易费用：决策费用、实施费用和监督费用过高，制约了我国政府供给公共产品的效率。制度的一项重要功能是降低交易成本，改革财政分权体制是降低政府供给公共产品发生的交易费用的有效途径。     

Tax Competition and International Public Goods

A well known result in the tax competition literature is that tax rates are set too low in the Nash equilibrium to finance an efficient level of public consumption goods. In this model we introduce international spillovers in public goods provision and show that such spillovers reduce, and in the limiting case of perfect spillovers, eliminate tax competition. There is, however, always underprovision of the public good in equilibrium, since larger spillovers increase the problem of free riding. In an extension to the model, we demonstrate that congestion costs may result in overprovision of the public good.     

Public‐Sector Accounting:A Common Reporting Framework? A Rejoinder

This article responds to some criticisms in Newberry's recent article in Australian Accounting Review concerning whether there is, or should be, a common reporting framework for public-sector and private-sector accounting. The Public Sector Accounting Standards Board supported this approach. Here, it is argued that business accounting is not appropriate for those parts of the public sector concerned with the provision of public goods to citizens. Following this article is a further rejoinder by Carnegie and Wolnizer, and a response by Newberry to both commentaries.     

Pawns and queens revisited: public provision of private goods when individuals make mistakes

This paper analyses the optimal tax policy and public provision of private goods when the government is paternalistic and has a redistributive objective. When individuals only differ with respect to their income-earning abilities, the publicly-provided goods should be overprovided, relative to the decentralised optimum, if society’s marginal valuation of them exceeds the individual valuation and if these goods are complements to labour supply. However, when the individuals also differ in terms of their valuation of the publicly-provided good, this simple conclusion does not hold. Optimal marginal income tax rates are shown to differ from the standard rules if publicly-provided goods and labour supply are related.      

Uncertainty in the Theory of Public Finance

This paper discusses the role that the economics of uncertainty has played in the theory of public finance. From being mostly concerned with its choice-theoretic foundations in the 1950s and 1960s, the theory of expected utility maximisation and risk averse behaviour has contributed decisively to the development of several areas of the theory of public finance. Three of these have been chosen here to illustrate the general point: The theory of taxation and risk taking with focus on portfolio choice, the role of uncertainty in public expenditure analysis (emphasising the effect of public goods provision on private risk taking) and the theory of tax evasion and compliance.
