Efficient Environmental Taxation Under Worker-Firm Bargaining

We study an economy with free firm entry and unemployment due to firm-worker bargaining over each firm's surplus, and where firms cause pollution that can be reduced by initial investments. An uncompensated increase in the pollution tax reduces pollution but increases unemployment, implying a tradeoff between the two. When tax revenues are used to subsidize either firms' hiring or investments, employment may also increase, creating a double dividend from the pollution tax. A pollution tax increase used to subsidize current employment is always less effective than a hiring subsidy, and is totally ineffective when subsidies equal pollution tax revenues for each individual firm. We show that the (hypothetical) pollution tax implementing the first-best solution exceeds the Pigouvian tax. The second-best tax exceeds this first-best tax when we have a double dividend, and is below it when we do not.     

From “tax state” to “debt state”

The paper is motivated by Joseph A. Schumpeter's The Crisis of the Tax State. It inquires whether the buildup of government debt in peacetimeprosperity is a threat to the stability, existence or creation of viable tax states. The paper begins by setting out Schumpeter's conception of the tax state and the nature of recent political-economic events which have reinvigorated the concept. Next the paper sets out some simple debt dynamics and sketches a debt-induced business cycle arising from heavy reliance on debt finance in peacetimeprosperity. Finally, the paper assesses threats to the tax state in light of recent work on path dependence and positive feedback. An attempt is made to throw some light on whether the plethora of new, and often small, states spawned by the demise of communism can be viable tax states.Essay on Government, the Tax State and Economic Dynamics submitted to the Third Schumpeter Prize Competition.     

Measuring the welfare effects of tax changes using the LES: An application to a carbon tax

This paper explores the use of a parametric approach to the measurement of compensating and equivalent variations resulting from price changes. The approach is based on the application of the Linear Expenditure System (LES) to each of a range of household income groups, rather than being based on a representative consumer. The method is then used to examine the distributional effects of a carbon tax, designed to reduce carbon dioxide emissions. The price changes resulting from a carbon tax depend on the carbon intensities of each good, which depend in turn on the nature of inter-industry transactions (the input-output matrix). The use of transfer payments to compensate for adverse distributional effects of a carbon tax is investigated, using social welfare functions based on equivalent incomes.     

Tax Interaction Effects,Environmental Regulation,and “Rule of Thumb” Adjustments to Social Cost

Preexisting distortions in factor markets complicate the estimation of the social welfare effects of regulatory interventions. The existence of these tax interaction effects (TIEs) suggests that general equilibrium (GE) approaches should be used to evaluate regulatory policies. However, formal GE analysis is not always feasible for the numerous environmental regulations proposed by federal, state, and local agencies. The question addressed in this paper is whether an empirically based rule of thumb upward adjustment factor is appropriate to properly scale social cost estimates in environmental policy. We argue that such rule of thumb adjustments are significantly less reliable than estimates based on a detailed general equilibrium analysis because of the uncertainty about both the magnitude and sign of the social cost distortion. In addition to addressing this question, the paper gives an overview of TIEs and their relevance to environmental policy.     

Die Komponenten des Rückganges der Ausländerbeschäftigung

Summary During the crisis of 1974/75 the number of foreign workers in Western European countries has been reduced. This has caused a new discussion about the benefits and drawbacks of the employment of foreign workers. Whatever the attitude towards this problem may be, it is useful to decompose the reduction of foreign labour into categories. First of all a certain amount of foreign labour will be reduced due to a general decrease of overall employment. This influence may be called proportionality effect. The share of foreign workers in the different branches of the economy allows the calculation of a structural effect. Both of them measure influences, which concern foreigners as well as nationals. Only the remaining influence is specific to foreigners. It may again be split into a reduction effect and a substitution effect. The former ist concerned with that part of total reduction of foreign workers, which corresponds to the decrease of employment, i.e. employment reduction by dismissal of foreign workers. The latter pertains to that part of reduction, which exceeds the decrease of employment, i.e. by this magnitude domestic labour has been substituted for foreign labour.The application of this model to the years 1974 and 1975 shows no proportionality effect (1974 it is even positive), a limited structural effect, but a high reduction effect. The substitution effect is considerable in 1974 but of minor importance in 1975. So foreign labour in Austria served actually as cyclical buffer but mainly by reduction and only partly by substitution.     

Corporate Lobbying, Regulatory Conduct and the Porter Hypothesis

Michael Porter, the influential Harvard management guru, has promoted the idea that compliance with stricter environmental regulations can afford secondary benefits to firms through improved product design, innovation, corporate morale and in other ways. Once these secondary benefits are factored, the net cost of compliance is argued to be lower than conventionally thought and may even be negative. Whilst environmental economists have rejected the Porter Hypothesis as being based on excessively optimistic expectations of the likely size of such secondary benefits the underlying ideas do enjoy significant credence in the business community. In the context of a lobbying model of regulatory policy-making we argue that the EPA should change the way it conducts regulatory policy to take account of Porter's views – even if it knows those views to be misguided. The model serves to illustrate the more general point that fashions in management thinking can be expected to impact the optimal conduct of regulatory policy.     

Biological Adaptation in Human Societies: a ‘Basic Needs’ Approach

The groundzero premise (so to speak) of the biological sciences is that survival and reproduction is the basic, continuing, inescapable problem for all living organisms; life is at bottom a survival enterprise. It follows that survival is the paradigmatic problem for human societies as well; it is a prerequisite for any other, more exalted objectives. Although the term adaptation is also familiar to social scientists, until recently it has been used only selectively, and often very imprecisely. Here a more rigorous and systematic approach to the concept of adaptation is proposed in terms of basic needs. The concept of basic human needs has a venerable history – tracing back at least to Plato and Aristotle. Yet the development of a formal theory of basic needs has lagged far behind. The reason is that the concept of objective, measurable needs is inconsistent with the theoretical assumptions that have dominated economic and social theory for most of this century, namely, valuerelativism and cultural determinism. Nevertheless, there have been a number of efforts over the past 30 years to develop more universalistic criteria for basic needs, both for use in monitoring social wellbeing (social indicators) and for public policy formulation. Here I will advance a strictly biological approach to perationalizing the concept of basic needs. It is argued that much of our economic and social life (and the motivations behind our revealed preferences and subjective utility assessments), not to mention the actions of modern governments, are either directly or indirectly related to the meeting of our basic survival needs. Furthermore, these needs can be specified to a first approximation and supported empirically to varying degrees, with the obvious caveat that there are major individual and contextual variations in their application. Equally important, complex human societies generate an array of instrumental needs which, as the term implies, serve as intermediaries between our primary needs and the specific economic, cultural and political contexts within which these needs must be satisfied. An explicit framework of Survival Indicators, including a profile of Personal Fitness and an aggregate index of Population Fitness, is briefly elucidated. Finally, it is suggested that a basic needs paradigm could provide an analytical tool (a biologic) for examining more closely the relationship between our social, economic and political behaviors and institutions and their survival consequences, as well as providing a predictive tool of some value.     

Attitudes Towards Paying Taxes in Austria: An Empirical Analysis

People mostly pay their taxes although there is a low probability of getting caught and being penalized. Thus, new attempts in the tax compliance literature try to go beyond standard economic theory. This paper examines citizens attitudes toward paying taxes – what is sometimes termed their tax morale, or the intrinsic motivation to pay taxes. Tax morale may be a key determinant to explain why people are honest. However, there are very few papers that explore the concept of tax morale theoretically and empirically. This study, based on the World Values Survey and the European Values Survey, therefore attempts to fill this gap in the literature, focusing on tax morale in Austria. Societal variables such as trust or pride have been identified as key determinants that shape tax morale in Austria. Furthermore, a lower perceived compliance leads to a decrease of tax morale, which indicates that social comparisons are relevant. The results also show a decrease of tax morale between 1990 and 1999, although Austrias taxpayers still have a very high tax morale compared to other European countries.     

The Double Dividend Debate: Some Comments from a Politico-Economic Perspective

During recent years, using theoretical and simulation models there has been an extensive debate about the welfare and employment effects of ecological taxes. This paper is a comment on this double dividend debate from a politico-economic perspective. First, a graphical representation of the main results of the theoretical models developed by Bovenberg et al. is given. After some remarks on the difference between the results of the theoretical and simulation models some more general remarks on welfare analysis and optimal taxation theory are made. After this, the question of the tax base is tackled. Finally, it is asked what we can learn from this debate for environmental policy purposes.     

Augmented serial rules for an excludable public good

Summary. We present a new class of rules named augmented serial rules for the provision of an excludable public good. First, we characterize this class by the four axioms of strategy-proofness, envy-freeness, access independence, and nonbossiness. Second, we identify two important subclasses by imposing an additional axiom: (i) anonymous augmented serial rules by anonymity, and (ii) Moulins serial rule by individual rationality.Received: 31 December 2002, Revised: 9 June 2004, JEL Classification Numbers: D71, D82, H41.This paper is a substantial revision of Serial cost sharing with simple games.

Anonymous sequential games: Existence and characterization of equilibria

Environmental market creation: saviour or oversell?

In recent years considerable attention has been paid to the notion of market creation for the conservation of environmental assets. Market creation establishes a market in the external benefit or cost in question (e.g. biodiversity or pollution reduction) and leaves the relevant parties to adjust their behaviour accordingly. While most attention has been paid to market creation through tradable permits and taxes (the polluter-pays), it is less easy to secure a perspective on beneficiary-pays initiatives. Both polluter-pays and beneficiary-pays initiatives are examples of modified Coaseian bargains in which governments intervene in the bargains to lower transactions costs, establish property rights, deal with public goods issues, or act on behalf of disadvantaged groups. This paper reviews four major initiatives in this respect - debt-for-nature swaps, bioprospecting and the Global Environment Facility at the global level, and the Costa Rican Forest Law at the local level. It finds that while there is much to applaud in initiatives in these new markets, serious questions remain about the modest flows of funds associated with such global bargains, and the extent to which they secure environmental improvements relative to the baseline of business-as-usual.JEL Classification: D49, D62, H41, O19, Q57, Q2I am indebted to members of the Wildlife Conservation Research Unit at Oxford University and to David Simpson of Resources for the Future and University College London for valuable comments on an earlier version of this paper.

Efficiency of Nonpoint Source Pollution Instruments: An Experimental Study

In nonpoint source pollution problems, the regulator does not observe each polluters individual emission, which prevents him from using the conventional policy instruments. Therefore, new instruments have been designed to regulate this type of pollution. In an experiment, we compare the efficiency of some of these instruments: an input-based tax, an ambient tax/subsidy, an ambient tax, and a group fine. We assume that polluters themselves are affected by environmental damages. A control session without any regulation is also carried out in order to study the status quo situation. Our experimental data show that the input tax and the ambient tax are very efficient and reliable, and the group fine is fairly efficient and reliable. These instruments improve social welfare with respect to the status quo. On the contrary, the ambient tax/subsidy decreases social welfare with respect to the status quo, and its effect is very unreliable.     

Institutional Evolution through Purposeful Selection: The Constitutional Economics of John R. Commons

The paper relates John. R. Commons view on the roleof human design in institutional evolution to the views thathave been advanced on this matter by F. A. Hayek, in German ordo-liberalism,and in constitutional political economy. It is argued that Commonsconcept of purposeful selection points in the direction ofa theoretical perspective that consistently integrates the notionsof institutional evolution and constitutional design.     

The greenhouse effect: Damages,costs and abatement

The buildup of so-called greenhouse gases in the atmosphere — CO₂ in particular-appears to be having an adverse impact on the global climate. This paper briefly reviews current expectations with regard to physical and biological effects, their potential costs to society, and likely costs of abatement. For a worst case scenario it is impossible to assess, in economic terms, the full range of possible non-linear synergistic effects. In the most favorable (although not necessarily likely) case (of slow-paced climate change), however, it seems likely that the impacts are within the affordable range, at least in the industrialized countries of the world. In the third world the notion of affordability is of doubtful relevance, making the problem of quantitative evaluation almost impossible. We tentatively assess the lower limit of quantifiable climate-induced damages at $30 to $35 per ton of CO₂ equivalent, worldwide, with the major damages being concentrated in regions most adversely affected by sea-level rise. The non-quantifiable environmental damages are also significant and should by no means be disregarded.The costs and benefits of (1) reducing CFC use and (2) reducing fossil fuel consumption, as a means of abatement, are considered in some detail. This strategy has remarkably high indirect benefits in terms of reduced air pollution damage and even direct cost savings to consumers. The indirect benefits of reduced air pollution and its associated health and environmental effects from fossil-fuel combustion in the industrialized countries range from $20 to $60 per ton of CO₂ eliminated. In addition, there is good evidence that modest (e.g. 25%) reductions in CO₂ emissions may be achievable by the U.S. (and, by implication, for other countries) by a combination of increased energy efficiency and restructuring that would permit simultaneous direct economic benefits (savings) to energy consumers of the order of $50 per ton of CO₂ saved. A higher level of overall emissions reduction — possibly approaching 50% — could probably be achieved, at little or not net cost, by taking advantage of these savings.We suggest the use of taxes on fossil fuel extraction (or a carbon tax) as a reasonable way of inducing the structural changes that would be required to achieve significant reduction in energy use and CO₂ emissions. To minimize the economic burden (and create a political constituency in support of the approach) we suggest the substitution of resource-based taxes in general for other types of taxes (on labor, income, real estate, or trade) that are now the main sources of government revenue. While it is conceded that it would be difficult to calculate the optimal tax on extractive resources, we do not think this is a necessary prerequisite to policy-making. In fact, we note that the existing tax system has never been optimized according to theoretical principles, and is far from optimal by any reasonable criteria.During the academic year 1989–90 Dr. Ayres was at the International Institute for Applied Systems Analysis (IIASA), Laxenburg, Austria.During the summer of 1989 Mr. Walter was a member of the Young Scientists' Summer Program at IIASA.     

A Note on Environmental Awareness and Cross-Border Pollution

Considering a Nash equilibrium in which a developed country chooses the amount of foreign aid and a developing country sets the emission tax rate and the proportion of the received aid allocated to public abatement of pollution, it is shown that an increase in the recipient countrys environmental awareness will reduce the level of cross-border pollution and benefits the donor though its foreign aid is increased.     

The measurement of entry rates: Recondiseration and resolution

This paper extends the recent analysis of Audretsch and Fritsch on entry rates, and suggests a resolution to the possible policy confusion which they discuss. British data also show very different results for the determinants of entry depending on whether the ecological or labour market entry rate is used. It is shown that, in addition to the static, size-distribution effect discussed by Audretsch and Fritsch, there are dynamic factors at work which may lead to this result. However, there need be no conflict in policy signals arising from this, because the labour market approach can be shown to be a superior measure of entry rates where spatial analysis is undertaken.     

Equilibria and Pareto optima of markets with adverse selection

Summary This paper examines the efficiency properties of competitive equilibrium in an economy with adverse selection. The agents (firms and households) in this economy exchange contracts, which specify all the relevant aspects of their interaction. Markets are assumed to be complete, in the sense that all possible contracts can, in principle, be traded. Since prices are specified as part of the contract, they cannot be used as free parameters to equate supply and demand in the market for the contract. Instead, equilibrium is achieved by adjusting the probability of trade. If the contract space is sufficiently rich, it can be shown that rationing will not be observed in equilibrium. A further refinement of equilibrium is proposed, restricting agents' beliefs about contracts that are not traded in equilibrium. Incentive-efficient and constrained incentive-efficient allocations are defined to be solutions to appropriately specified mechanism design problems. Constrained incentive efficiency is an artificial construction, obtained by adding the constraint that all contracts yield the same rate of return to firms. Using this notion, analogues of the fundamental theorems of welfare economics can be proved: all refined equilibria are constrained incentive-efficient and all constrained incentive-efficient allocations satisfying some additional conditions can be decentralized as refined equilibria. A constrained incentive-efficient equilibrium is typically not incentive-efficient, however. The source of the inefficiency is the equilibrium condition that forces all firms to earn the same rate of return on each contract.Notation ={ ₁,..., _k } set of outcomes - : ₊ generic contract or lottery - A = () ; - A_o A{, where denotes the null contract or no trade - S={1,...,¦S¦} set of seller types - L(s) number of type-s sellers - M number of buyers - u: × S seller's utility function, which can be extended toA× S by puttingu(, s) ; - v. × S buyer's utility function, which can be extended toA × S by puttingv(, s) ; - f:A ₀ ×S ₊ allocation of sellers - g:A ₀ ×S ₊ allocation of buyers - A ₊ sellers' trading function - :A ×S ₊ buyers' trading function This paper has had a long gestation period, during which I have been influenced by helpful conversations with many persons, by their work, or both.

Endogenous Growth and Natural Resource Scarcity

Endogenous growth theory has rekindled interest in the role of innovation in determining long-term economic growth. Generally, this body of literature has ignored the contribution of natural resources to growth or the role of innovation in overcoming resource scarcities. The latter problem has been a focus of resource economics for many years, but innovation is usually modelled as exogenous rather than endogenous technological change. Recent investigations in political economy have additionally suggested that the supply of innovation may itself be constrained by resource scarcities, especially in the developing world. The following paper attempts to bridge these theoretical gaps through the formal analysis of two issues: First, a simple Romer-Stiglitz model of endogenous growth with resource scarcity and population growth is developed to determine the optimal balanced growth path for the economy. Second, the basic model is extended to allow for the possibility of resource availability constraining the supply of innovation, so that in the long run innovation net of any resource constraint is zero. However, under the latter conditions it is still possible to avoid resource exhaustion and thus achieve a constant level of per capita consumption in the long run. The paper therefore demonstrates that endogenous growth can overcome resource scarcity, but the outcome in the long run depends critically on assumptions concerning any constraints imposed by resource availability on the generation of innovation.
