the impacts of urban pricing on social and spatial inequalities the case study of lyon france with the aim of making a city sustainable this paper evaluates the impact of setting up urban toll on inequalities we use several indicators gini theil and atkinson indices to measure changes in the concentration of incomes and gravity based accessibility in the case of the lyon metropolitan area france we simulate a cordon pricing and evaluate its impacts on inequalities we adopt a comparison based approach to reduce the bias resulting from the spatial division in agreement with the literature we show that different inequality indicators produce contrasted and sometimes contradictory results both at the scale of zones or metropolitan level results from theil and atkinson indicators point out introducing a toll can reduce inequalities in the most peripheral zones although we observe an accessibility improvement particularly for central zones the first ring adjacent to the toll zone is the most adversely affected by toll

the incidence of congestion tolls on urban highways abstract the incidence of an optimal short run congestion toll is investigated using an equilibrium model of modal choice and congestion on a highway corridor served by express bus transit it is argued that for an externality tax the usual equi revenue analysis of burdens is inappropriate instead welfare effects are computed under three alternative assumptions about redistribution of toll revenues in almost all cases the net result is benefits for all income groups it is concluded that congestion tolls should not be rejected on grounds of income distribution but that an explicit package of tolls and revenue uses is probably a political prerequisite for adoption

optimal commodity taxation and tax reform under unemployment this paper derives the optimal commodity tax formula and the tax reform rule which should be used in a situation of orthodox keynesian unemployment the setting considered is a four good one individual model with fixed real wage implying an excess supply of labor the presentation is very simple and based on intuitive and graphical arguments the emphasis is on comparing our results with the more traditional results derived under full employment

pigou meets mirrlees on the irrelevance of tax distortions for the second best pigouvian tax this paper extends the mirrlees 1971 model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities using general utility structures and exploring both linear and non linear taxes it is demonstrated that the optimal second best tax on an externality generating good should not be corrected for the marginal cost of public funds since it equals one in the optimal tax system in the optimum distortions of income taxes are equal to marginal redistributional gains if the government does not have access to a non distortionary marginal source of finance the marginal cost of public funds can be either larger or smaller than one depending on subjective preferences for income redistribution the optimal second best corrective tax is then either higher or lower than the pigouvian level the findings in this paper generalize and amend prior results based on representative agent models shedding new light on the weak double dividend hypothesis and on the welfare gains of recycling revenue from environmental taxes

marginal commodity tax reforms a survey as noted 30 years ago by martin feldstein optimal taxes may be useless for practical purposes and emphasis should instead be placed on the possibility of enhancing welfare by reforming existing tax rates in this perspective marginal commodity tax reforms are gaining increasing attention due to political and economic constraints on large reforms of direct or indirect taxation in this paper we summarize the main features and results of the literature on marginal commodity tax reforms pioneered by ahmad and stern further developed by yitzhaki and thirsk and recently reinterpreted by makdissi and wodon we establish new links to other fields of research namely the literature on the use of equivalence scales and on poverty measurement we also critically examine some issues associated with the implementation of marginal tax reforms with special reference to the calculation of welfare weights and revenue effects finally we suggest directions for future research on poverty reducing commodity tax reforms

comparative advantage and the equilibrium rate of unemployment abstract this paper develops a two country heckscher ohlin model with endogenous equilibrium involuntary unemployment to examine the question wat is the effect of free trade on the equilibrium rates of unemployment in the laborabundant and labor scarce countries it is shown that free trade leads to a decline in the equilibrium rate of unemployment in the labor abundant country but to a rise in unemployment in the labor scarce country

jobs and chocolate samuelsonian surpluses in dynamic models of unemployment in dynamic models of unemployment in which the employed consume more than the unemployed workers are finitely lived and jobs are lasting employment transfers consumption from future generations to those currently alive resulting in a social surplus that is these transfers allow the current generation to consume more than its share of the output produced during its lifetime without the increased consumption coming at the expense of future generations moreover due to these intergenerational transfers the allocation that maximizes steady state output is pareto dominated by another feasible allocation with a higher level of steady state employment

sustainability impacts of car road pricing a computable general equilibrium analysis for austria abstract nationwide car road pricing schemes are discussed across europe we analyse the impacts of such schemes with respect to environmental economic and social indicators of sustainability also quantifying the trade offs among these three dimensions under different charging principles and revenue recycling options in our analysis we employ a computable general equilibrium cge approach develop a modelling structure for private transport and provide detailed empirical analysis for the case of austria regarding the social dimension it has often been argued that poorer households and commuters would have to bear a disproportionate share of the road pricing burden we find the contrary i e a stronger negative policy impact on richer households and on a small group of intensive car users the choice of revenue recycling is able to ameliorate the negative social and economic effects of road pricing without reversing the desired positive environmental effects for political feasibility questions of distributional impacts are most urgent and therefore we address them systematically within a quantitative framework

equity based natural resource allocation for infrastructure development evidence from large hydropower dams in africa and asia abstract large hydropower infrastructure development is a key energy priority in low and middle income countries as a means to increase energy access and promote national development nevertheless hydropower dams can also negatively impact people s livelihoods by reducing access to local natural resources such as land water and food this paper analyses equity based resource allocation from an ecological economics perspective by looking at local resource use competition between different uses food energy livelihoods and users villagers urban settlers local government and dam builders in selected case studies in asia and africa it also illustrates from a political ecology approach divergences between national priorities of energy production and growth and local development needs

second best congestion pricing schemes in the monocentric city abstract this paper considers second best congestion pricing in the monocentric city with endogenous residential density and endogenous labour supply a spatial general equilibrium model is developed that allows consideration of the three way interactions between urban density traffic congestion and labour supply congestion pricing schemes are analysed that are second best by design and not because distortions exist elsewhere in the spatial economy like cordon charging and flat kilometre charges both for cobb douglas utility and for ces utility the analyses suggest that the relative welfare losses from second best pricing compared to first best pricing are surprisingly small

environmental kuznets curves real progress or passing the buck abstract recent research has examined the hypothesis of an environmental kuznets curve ekc the notion that environmental impact increases in the early stages of development followed by declines in the later stages these studies have focused on the relationship between per capita income and a variety of environmental indicators results imply that ekcs may exist for a number of cases however the measures of environmental impact used generally focus on production processes and reflect environmental impacts that are local in nature and for which abatement is relatively inexpensive in terms of monetary costs and or lifestyle changes significantly more consumption based measures such co2 emissions and municipal waste for which impacts are relatively easy to externalize or costly to control show no tendency to decline with increasing per capita income by considering consumption and trade patterns the author re examines the concept of the ekc and proposes the use of alternative consumption based measures of environmental impact the author speculates that what appear to be improvements in environmental quality may in reality be indicators of increased ability of consumers in wealthy nations to distance themselves from the environmental degradation associated with their consumption

how robust is the uniform emissions pricing rule to social equity concerns abstract this paper examines pollution tax differentiation across industries in light of social equity concerns using theoretical and numerical general equilibrium analyses in an optimal tax framework we characterize the drivers for non uniform optimal taxes stemming from the interaction of household heterogeneity with social preferences quantitatively assessing the case of price based co2 emissions control in the u s economy we find that uniform emissions pricing is approximately optimal when social concerns are defined over inequity induced by the environmental tax the deviation from uniform emissions pricing however becomes non negligible when pollution tax rebates deviate much from optimal transfer schemes or when social concerns are defined over both policy induced impacts and inequity unrelated to environmental policy our results are robust to a number of model extensions including the stringency of the environmental target downstream vs upstream taxation pre existing distortionary taxes and parametric uncertainty in firms and households equilibrium tax responses

marginal tax reform externalities and income distribution the paper examines welfare improving and revenue neutral directions marginal policy reforms for an economy with nonidentical individuals and an externality that has a feedback effect on the consumption of taxed goods it considers three types of policy instruments the indirect taxes the uniform poll transfer and public abatement this extends the framework set up by ahmad and stern 1984 bovenberg and de mooij 1994 and schob 1996 the theoretical model is illustrated for a specific externality namely congestion caused by peak car transport

environmental policy public finance and the labour market in a second best world abstract environmental and tax policies and the optimal provision of clean and dirty public goods are analysed within the context of a second best framework of optimal taxation households consume both clean and dirty commodities degradation of the natural environment occurs due to the consumption of dirty private and public goods but can be offset when the government engages in abatement activities increased environmental concern implies a higher dirt tax a lower tax on labour less employment more public abatement and a cleaner environment if the elasticity of substitution between private consumption commodities and leisure is large and that between clean and dirty goods is small public consumption may expand while private consumption contracts otherwise public consumption falls

equity effects of alternative assignments of global environmental rights abstract through a thought experiment in which members of different generations trade with each other in a virtual market we examine the effects of alternative assignments of global environmental rights on prices interest rates and the global distribution of income the model is semi calibrated to current and projected levels of the output of produced goods and to present and future quantities of global environmental goods income classes in each country are disaggregated to the quintile level multiple equilibria are possible for some rights assignments with implications for intergenerational equity the model projects bounds on the degree of future economic inequality depending on how the environmental rights are assigned a policy that assigns the environmental rights in such a way as to leave the present day distribution of income unchanged while moving in the direction of equal per capita endowments of environmental rights can result in future inequality comparable to today s average within country inequality

child labor and globalization the article embeds child labor in a standard general equilibrium two sector model of a small open economy facing perfectly competitive markets efficiency wages and free trade the modern sector uses skilled adult labor and capital and the agrarian sector uses unskilled child and adult labor and skilled adult labor trade policies foreign direct investment or both that increase the modern sector output reduce the incidence of child labor emigration of skilled unskilled workers reduces increases the incidence of child labor child wage subsidies increase the incidence of child labor and a ban on child labor benefits unskilled adult workers but hurts skilled workers

the environment and the ethics of discounting an empirical analysis abstract this paper examines the application of discount rates by individuals and by governments when they make decisions about environmental resource use the paper is presented in the context of ethics as determined by what is good and also by what is right for society since in this instance there appears to be no conflict between the two perspectives in addition the paper assesses whether ethical considerations are included in decision making frameworks at the individual and community levels consistency of discount rate applications between individuals and governments is also investigated since consistency is an element of ethical arguments empirical data from a study of soil conservation adoption by philippines upland farmers are used in the analysis individual discount rates are assessed in relation to income and poverty interest rates paid on debt purpose of borrowings land tenure income inequality and soil conservation adoption some of the results appear to be counter intuitive and reasons for this phenomenon are sought the overall results have policy implications and suggestions are made about how an ethical perspective might be developed by governments to help ensure that decision making criteria are more consistent with the practices of individuals within the communities they serve it is suggested that this approach would lead to greater intergenerational and intragenerational equity and better environmental quality

compact or spread out cities urban planning taxation and the vulnerability to transportation shocks this paper shows that cities made more compact by transportation taxation are more robust than spread out cities to shocks in transportation costs such a shock indeed entails negative transition effects that are caused by housing infrastructure inertia and are magnified in low density cities distortions due to a transportation tax however have in absence of shock detrimental consequences that need to be accounted for the range of beneficial tax levels can therefore be identified as a function of the possible magnitude of future shocks in transportation costs these taxation levels which can reach significant values reduce city vulnerability and prevent lock ins in under optimal situations

discounting and distributional considerations in the context of global warming the economics of global warming is reviewed with special emphasis on how the cost depends on the discount rate and on how costs in poor and rich regions are aggregated into a global cost estimate both of these factors depend on the assumptions made concerning the underlying utility and welfare functions it is common to aggregate welfare gains and losses across generations and countries as if the utility of money were constant but it is not if we assume that a e co2 equivalent dlubling implies costs equal to 1 5 of the income in both high and low income countries a pure rate of time preference equal to zero and a utility function which is logarithmic in income then the marginal cost of co2 emissions is estimated at 260 590 usd ton c for a time horizon in the range 300 1000 years an estimate which is large enough to justify significant reductions of co2 emissions on purely economic grounds the estimate is approximately 50 100 times larger than the estimate made by nordhaus in his dice model and the difference is almost completely due to the choice of discount rate and the weight given to the costs in the developing world as well as a more accurate model of the carbon cycle finally the sensitivity of the marginal cost estimate with respect to several parameters is analyzed

reevaluating the first and the second dividends of environmental tax reforms abstract there is increasing global interest in market based climate change policies following the last elections in the united states in this context an exxon mobil chief executive came out in favour of a carbon tax this paper is concerned with the welfare analysis of environmental tax reforms etr and takes up the claims for the need of an unambiguous and operative definition of the double dividend both for empirical purposes and political advisement in this paper we contest the usual definition of the second dividend and its assimilation to an efficiency dividend we propose alternative definitions by suggesting a different splitting of the total welfare variation between the first and the second dividend in order to isolate the efficiency effects of the etr the new definitions become clearly understandable and easy for economic and policy interpretation concepts like weak and strong double dividend turn out to be unnecessary finally we analyze etr for the us economy to illustrate the advantages of the proposed definitions for policy implementation

will a radical transport pricing reform jeopardize the ambitious eu climate change objectives abstract this paper examines the effects of replacing current fuel taxes by a system of taxes that account better for all the different external costs of the different transport modes one of the important implications of this reform is that current fuel taxes are decreased to a level of 80 euro ton of co 2 but that the mileage related taxes on car and truck use increase using the tremove model for the transport sector of 31 european countries one finds that the volume of transport will decrease because current taxes on transport are too low compared to overall external costs overall co 2 emissions will decrease slightly using the markal times model for the belgian energy sector putting all sectors and technologies on equal footing shows that a fuel tax reform makes that it is not cost efficient to require large co 2 emission reductions in the transport sector and that traditional car technologies will continue to dominate the car market in 2020 2030

on revenue recycling and the welfare effects of second best congestion pricing in a monocentric city abstract this paper examines congestion taxes in a monocentric city with pre existing labor taxation when road toll revenue is used to finance labor tax cuts 35 of the optimal road tax in our numerical model does not reflect marginal external congestion costs but rather functions as a ramsey mirrlees tax i e an efficiency enhancing mechanism allowing for an indirect spatial differentiation of the labor tax this adds a quite different motivation to road pricing since welfare gains can be produced even in absence of congestion we find that the optimal road tax is non monotonic across space reflecting the different impacts of labor supply elasticity and marginal utility of income which both vary over space the relative efficiencies of some archetype second best pricing schemes cordon toll flat kilometer tax are high 84 and 70 respectively when road toll revenue is recycled lump sum the optimal toll lies below its pigouvian level extensions in a bimodal framework show that the optimality of using road toll revenue to subsidize public transport depends on the initial inefficiency in public transport pricing

second best analysis with markets in disequilibrium public sector pricing in a keynesian regime the paper develops pricing rules for a public sector subject to a budget constraint in an economy where the private sector experiences keynesian unemployment excess supply of labour and of commodities both second best and welfare improving pricing rules are studied it is found that such rules can be defined in operational terms in general they are quite complex involve quantities which are not directly observable reservation wages and prices and require evaluation of income and employment multipliers the general equilibrium approach to second best theory thus involves standard macroeconomic concepts and techniques some discussion of methodological issues and of policy objectives inflation versus unemployment is offered in order to facilitate interpretation the corresponding results for an economy with a competitive private sector are first restated

diet and the distribution of environmental impact abstract this paper examines the relationship between scale and distribution issues it is argued that since achieving a sustainable scale requires economic activity to stay within biophysical limits considerations of equity should not be limited to the distribution of monetary measures such as income but should include the distribution of scarce environmental services as well in order to make this point this paper examines how differences in diet across populations lead to inequality in the distribution of environmental impact first the distribution of food consumption across the world s population is examined using national data next ecological footprints are estimated in order to ascertain how differences in diet affect the distribution of environmental impact the results show that the meat intensive diet enjoyed by many in the industrialized world leads to a greater degree of inequality in the use of environmental services than is apparent from examination of the distribution of food consumption across countries

a just and efficient reduction of resource throughput to optimum abstract resource throughput in the economy e g of energy or materials must be progressively reduced by at least one order of magnitude to achieve an optimal level although this would solve the resource distribution conflict between the generations it would also aggravate the resource distribution conflict between persons of the same generation it is shown here that a solution to these two conflicts and efficient resource allocation are only possible if resource certificates are distributed to consumers free of charge and traded between them this paper builds on and integrates ideas developed in h daly s daly h e 1992 allocation distribution and scale towards an economics that is efficient just and sustainable ecological economics 6 185 193 article on allocation distribution and scale adding insights from the ecological footprint concept to propose a mechanism for facilitating intergenerational equity and drastically reducing resource throughput basically the mechanism involves rationing throughput equitably internalizing environmental and social externalities and substituting labour for resource use this can be achieved almost without a drop in prosperity both unemployment and dependence on scarce resources decline

does britain or the united states have the right gasoline tax this paper develops an analytical framework to assess the second best optimal level of gasoline taxation taking into account unpriced pollution congestion and accident externalities as well as interactions with the broader fiscal system we provide calculations of the optimal taxes for the us and the uk under a variety of parameter scenarios under our central parameter values the second best optimal gasoline tax is 1 01 gal for the us and 1 34 gal for the uk current tax rates are much lower than this in the us and higher in the uk the calculations are moderately sensitive to alternative parameter assumptions the congestion externality is the largest component in both nations revenue raising needs also play a significant role as do accident externalities and local air pollution potential welfare gains from reducing the current uk tax rate are estimated at nearly one fourth the production cost of all gasoline used in the uk even larger gains could be achieved by switching to a tax on vehicle miles with equal revenue yield for the us the welfare gains from optimizing the gasoline tax are smaller but those from switching to an optimal tax on vehicle miles are very large

optimal tax and public investment rules for congestion type of externalities optimal government policy is considered in a second best framework where consumers and producers cause an externality of the congestion type and income distribution issues are taken into account the theoretical results of the optimal tax literature are adapted using the concept of the net social pigouvian tax an illustrative age model uncovers the relative importance of its components the model demonstrates that the level of the externality tax does not depend strongly on distribution concerns as reoptimization of the other taxes ensures that the income distribution objective is reached the model also allows us to study the interaction between externality taxes and public abatement

a political economy model of road pricing abstract in this paper we use a simple majority voting model to study the introduction of urban congestion tolls the model allows for different types of uncertainty and considers different uses of the toll revenues the following results are obtained first we show that individual uncertainty with respect to modal substitution costs may imply that a majority votes against road pricing ex ante although a majority would have been in favor after its introduction ex post moreover if a majority is against road pricing ex ante there will also be no majority for organizing an experiment that would take away the individual uncertainty second political uncertainty with respect to the use of the revenues corroborates the finding that ex ante more voters will be against the introduction of tolls third both types of uncertainty suggest that fewer voters are against road pricing when toll revenues are used to subsidize public transport than when they are redistributed to all voters importantly the results of this paper are consistent with a number of recent empirical observations on efforts to introduce road pricing including the systematic rejection of road pricing in referenda the more favorable attitudes towards road pricing after than before its introduction and tying the toll revenues to support public transport

behaviors and housing inertia are key factors in determining the consequences of a shock in transportation costs this paper investigates the consequences of a sudden increase in transportation costs when household behaviors and building inertia are accounted for a theoretical framework is proposed capturing the interactions between behaviors transportation costs and urban structure numerical simulations show that changes in households and landowners choices reduce significantly the long term adverse effects of a shock in transportation costs indeed the shock translates over the long run into a more concentrated housing that limits households utility losses and maintains landowners income but because of building inertia the shock leads first to a long transition during which the adjustment is constrained by a suboptimal housing supply structure then households support larger losses than in the final stage though lower than with no behavior adjustment and landowners experience a large decrease in their aggregate income and an important redistribution of wealth thus behaviors and building inertia are key factors in determining the vulnerability to transportation price variability and to the introduction of climate policies our policy conclusions are that i if a long term increase in transportation costs is unavoidable because of climate change or resource scarcity a smooth change prevents to some extent the negative transition effects and ii fast growing cities of the developing world can reduce their future vulnerability to shocks in transportation costs through the implementation of policies that limit urban sprawl

economic growth and environmental degradation the environmental kuznets curve and sustainable development abstract in this paper we critically examine the concept of the environmental kuznets curve ekc it proposes that there is an inverted u shape relation between environmental degradation and income per capita so that eventually growth reduces the environmental impact of economic activity the concept is dependent on a model of the economy in which there is no feedback from the quality of the environment to production possibilities and in which trade has a neutral effect on environmental degradation the actual violation of these assumptions gives rise to fundamental problems in estimating the parameters of an ekc the paper identifies other econometric problems with estimates of the ekc and reviews a number of empirical studies the inference from some such ekc estimates that further development will reduce environmental degradation is dependent on the assumption that world per capita income is normally distributed when in fact median income is far below mean income we carry out simulations combining ekc estimates from the literature with world bank forecasts for economic growth for individual countries aggregating over countries to derive the global impact within the horizon of the bank s forecast 2025 global emissions of so 2 continue to increase forest loss stabilizes before the end of the period but tropical deforestation continues at a constant rate throughout the period

humans environment and economies from vicious relationships to virtuous responsibility abstract the debates questioning the meaning of growth point to a need for a more holistic understanding of human beings and of the economic actor fundamental to economic theory and practice this contribution turns to virtue ethics in order to reframe the self in more reflexive relational and environmental terms we explore the significance of understanding humans sense of responsibility that is quintessentially relational and of their capacity and need to relate to nature as well as community and society we begin by reviewing the main arguments in the thriving debate in ecological economics around what the characteristics of the human being can contribute to implement an ecologically sustainable development our aim is then to draw a link between this debate and that of virtue ethics that leads to a different understanding of the human being of what can contribute to individual wellbeing and a good life responsibility we argue is not only a value but a virtue that enables individuals to find meaning in acting responsibly towards the environment emphasising the multiple benefits that arise from framing good lives in active terms we conclude reflecting on the challenges to and implications of our proposition for government institutions particularly education

on the conceptual foundations of ecological economics a teleological approach abstract nature is characterised by the emergence and continued existence of far from equilibrium self organizing dissipative structures ffesods which can be described in terms of their genotypes potentialities and phenotypes realizations if a ffesods genotype is contained within its phenotype we call it an organism we can describe the behaviour of organisms as being teleological we offer three tele for organisms first telos self maintenance development and self realization second telos replication and renewal third telos service to other organisms to other species or to the whole of nature sustainability of an ecosystem requires a balance and harmony between these mutually supporting tele we define the related concepts of stock store and fund we can interpret all living activity be it natural or economic in terms of relationships between funds through the three tele we can characterise the environmental problems in the first world as stemming from too great an emphasis by humans on the first telos through consumerism and too little emphasis on the third telos in the third world we can identify environmental problems with an imbalance towards the second telos reproduction leading to a de emphasis of the third telos the long run solution to global environmental problems must lie in the re establishment of global harmony between the three tele of both humans and non humans

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

allocation distribution and scale towards an economics that is efficient just and sustainable abstract the practical policy of issuing tradeable permits for depletion and pollution requires for its implementation the clear separation of the three basic economic goals of efficient allocation equitable distribution and sustainable scale economic theory needs to catch up with policy in recognizing that scale issues cannot be reduced to either allocation or distribution

rural urban wage differentials unemployment and efficiency wages an open economy policy analysis this paper analyzes the desirability of various policies designed to counteract the distorting nature of an equilibrium rural urban wage differential in a small open two sector economy with urban unemployment a dual labor market model with an efficiency wage in the urban sector and urban unemployment is analyzed for the distributional and national output effects of an urban wage subsidy an urban production subsidy and a tariff on the urban good while a small subsidy or tariff raises the value of national output redistribution effects may limit the viability of intervention however subsidies can also be pareto improving policies

the greenhouse effect and intergenerational transfer abstract the scientific basis for understanding the economic issues involved in the greenhouse effect is outlined four important aspects of the problem are identified and discussed irreversibility international and institutional constraints uncertainty and intergenerational equity attention is focused upon the intertemporal choice problem a model describing the potential for intergenerational transfers under the uncertainty of climatic change due to fossil fuel combustion is presented we conclude intergenerational compensation can be achieved by investment in capital or technology or by bequest and is ethically required regardless of any other action

the theory of reform and indian indirect taxes abstract given a set of value judgements an initial state and a model of the economy one can ask whether some feasible tax change would increase welfare we do this by defining the marginal cost in terms of welfare of raising an extra rupee from the i th good the inverse optimum problem is the calculation of non negative welfare weights on households which imply that the initial state is optimum if no such welfare weights exist then a pareto improvement is possible we illustrate the concepts and results using data from the indian economy for 1979 1980 directions of tax reform for a number of specific social welfare functions and for pareto improvements are presented

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

agreeing to pay under value disagreement reconceptualizing preference transformation in terms of pluralism with evidence from small group deliberations on climate change abstract plural values contribute to multiple arrays of expressed preferences conventionally preference convergence toward consensus among initially disagreeing decision makers is understood in terms of diminishing value differences a cogent account of consensual decision that respects non diminishing value plurality is lacking instead there is a theoretic expectation for categorical consistency between subjective values and expressed preferences valuing agents in social interaction are expected to indicate identical preference orderings only if they hold correspondingly identical categories of values this expectation precludes meaningful conceptualization of preference convergence under divisive normative dispositions an alternative framework is proposed and illustrated by results from a designed deliberative forum on australia s climate change policy data were analyzed based on q methodology results show that small group deliberations enabled effective communication between distinctive subjective positions and broadened understandings between individuals while a consensual decision gained progress no identified value discourse diminished below a significant degree observed changes in values did not run parallel to the converging preferences suggesting a decline in value preference consistency these changes nonetheless are amenable to the principle of value pluralism an alternative rationality concept is needed to account for this moral ideal within economics

winning or losing from dynamic bottleneck congestion pricing the distributional effects of road pricing with heterogeneity in values of time and schedule delay abstract this paper analyses the efficiency and distributional impacts of congestion pricing in vickrey s 1969 dynamic bottleneck model of congestion allowing for continuous distributions of values of time and schedule delay we find that congestion pricing can leave a majority of travellers better off even without returning the toll revenues to them we also find that the consumer surplus losses or gains from tolling are not strictly monotonic in the value of time because they also depend on the value of schedule delays the greatest losses are not incurred by drivers with the lowest value of time but by users with an intermediate value of schedule delays and the lowest value of time for that value of schedule delays for second best pricing with an untolled alternative the pattern of distributional effects is quite similar to that for first best pricing in contrast with results from prior static models users who are indifferent between the two alternative routes are not the ones who gain least from this type of second best pricing our results suggest that in assessing the distributional impacts of road congestion pricing it is important to take into account both the distribution of the value of time and of the value of schedule delays as well as the dynamics of departure time choice

ecology and valuation big changes needed abstract ecological economics has developed as a transdisciplinary science but it has not taken significant steps toward a truly integrated process of evaluating anthropogenic ecological change the emerging dominance within ecological economics of the movement to monetize ecological services when combined with the already well entrenched dominance of contingent pricing as a means to evaluate impacts on amenities has created a monistic approach to valuation studies it is argued that this monistic approach to evaluating anthropogenic impacts is inconsistent with a sophisticated conception of ecology as a complex science that rests on shifting metaphors an alternative pluralistic and iterative approach to valuation of anthropogenic ecological change is proposed

aggregation and deliberation in valuing environmental public goods starting from a distinction between kantian principle based and utilitarian preference based approaches in political theory this essay argues that we may understand normative judgments individuals make about policy to express principled views of the public interest or purpose not private preferences about their own consumption opportunities these judgments in other words state opinions about what we ought to do as a society rather than report preferences about what i want as a utility maximizer this essay then argues that contingent valuation can take into account these kinds of judgments which dominate public discourse about the environment only if it moves toward a deliberative discursive jury like research method emphasizing informed discussion leading toward a consensus based on an argument about the public interest

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

trade and relative wages the role of supervisory function by skilled workers abstract the effect of trade on relative wages is examined taking into consideration some aspects of internal organization of firms namely the twin function of production and supervision by skilled workers when trade is based on endowment differences the effect of trade is greater than is predicted by the stolper samuelson theorem when trade is based on technological differences freer trade tends to reduce the relative wages in each country in a two country world economy

environmental taxes with heterogeneous consumers an application to energy consumption in france abstract this paper constructs a model with four groups of households who have preferences over labor supply consumption of polluting energy related and non polluting non energy goods and emissions it quantifies the model for the french economy and computes its optimal tax equilibria under nine second best tax regimes we find that the redistributive role of environmental taxes requires the polluting goods to be taxed at a rate much below their marginal social damage these goods may even require an outright subsidy if the society values equality a lot secondly if environmental taxes that have an exclusively externality correcting role they benefit all types although the gains are rather modest the gains and losses become more substantial when environmental taxes have a redistributive role as well third setting the environmental tax at its pigouvian level rather than its optimal externality correcting cum redistributive level benefits the high income group at the expense of the low income groups fourth nonlinear taxation of polluting goods and nonlinear commodity taxation in general is a powerful redistributive mechanism fifth introducing environmental taxes in the current french tax system with its suboptimal income taxes results in substantial welfare gains for the highest income group and a sizable loss for the least well off persons

values ideology and politics in ecological economics abstract ecological economics is built on a value commitment to study environmental issues and to contribute constructively to a more sustainable development path however many ecological economists still hesitate it appears to depart too much from other scholars by openly addressing issues of values and ideology in this essay the role of the scholar s orientation with respect to values and ideology is addressed it is observed that not only scholars but also actors in society are guided by their ideological orientation this leads to the idea that some of the weaknesses of economic man and profit maximising firm assumptions can be mitigated by introducing a political economic person and a political economic organisation

labour supply and commuting abstract we examine the effect of commuting distance on workers labour supply patterns distinguishing between weekly labour supply number of workdays per week and daily labour supply we account for endogeneity of distance by using employer induced changes in distance in germany distance has a slight positive effect on daily and weekly labour supply but no effect on the number of workdays the effect of distance on labour supply patterns is stronger for female workers but it is still small

beyond homo economicus evidence from experimental economics environmental policies are generally based on a model of the human actor taken from neoclassical economic theory this paper reports on laboratory experiments suggesting weaknesses in this model and describes alternative models correcting these weaknesses one finding is that economic actors tend to be hyperbolic as opposed to exponential discounters who discount the immediate future at a higher rate than the more distant future another finding is that economic actors are not self regarding but rather in many circumstances are strong reciprocators who come to strategic interactions with a propensity to cooperate respond to cooperative behavior by maintaining or increasing cooperation and respond to free riders by retaliating against the offenders even at a personal cost and even when there is no reasonable expectation that future personal gains will flow from such retaliation we discuss some implications for policy analysis 2000 elsevier science b v all rights reserved

optimal environmental taxation in the presence of other taxes general equilibrium analyses this paper examines the optimal setting of environmental taxes in economies where other distortionary taxes are present we employ analytical and numerical models to explore the degree to which in a second best economy optimal environmental tax rates differ from the rates implied by the pigovian principle according to which the optimal tax rate equals the marginal environmental damages both models indicate contrary to what several analysts have suggested that the optimal tax rate on emissions of a given pollutant is generally less than the rate supported by the pigovian principle moreover the optimal rate is lower the larger are the distortions posed by ordinary taxes numerical results indicate that previous studies may have seriously overstated the size of the optimal carbon tax by disregarding pre existing taxes this abstract was borrowed from another version of this item

support and opposition to a pigovian tax road pricing with reference dependent preferences abstract loss aversion can affect support and opposition to pigovian taxes to reduce externalities this paper studies road pricing with reference dependent preferences modeled by a linear gain loss utility function given this specification we find that the socially optimal road toll is smaller than the optimal toll in the absence of reference dependence and it declines in the degree of loss aversion loss aversion can also explain the empirical observation that support for road pricing is lower before than after its introduction we further show that loss aversion may increase or reduce lobbying efforts by driver organizations against the introduction of tolling it will increase lobbying if a high toll is proposed but drivers initially believe that the probability that it will be introduced is small lastly loss aversion unambiguously reduces lobbying by organizations of non drivers representing for example environmentalists or public transport users in favor of the introduction of a toll

household transport demand in a cge framework the main objective of this study is to improve the modelling of household demand for transport services in a computable general equilibrium cge model the new extended model is then used for numerical calculations to test how the swedish economy reacts to a carbon target special attention will be given to distributional effects and the connection between labour supply and work journeys in a sparsely populated country like sweden a differentiation between trip purposes and trip length a complementary relationship between work journeys and labour supply and a subdivision of households by density of population and income influence the numerical results our main conclusions from the analysis of a carbon target are that if the carbon tax revenue is recycled by decreasing the employers social contribution fee welfare costs are lower than with lump sum replacements of tax revenue to households the welfare cost may be reduced even further if work journeys are not additionally taxed as compared to the base year however the lower total welfare cost is obtained at the expense of making society more unequal since both labour tax recycling cuts in employers social contributions and exempting tax on work journeys will make low income groups carry a higher burden an increased carbon dioxide tax is also shown to increase welfare differences between sparsely populated areas and city regions in sweden

tax revenue and the marginal cost of public funds in sweden abstract we assess the welfare cost of raising a marginal unit of tax revenue in a balanced budget general equilibrium framework the calculated social cost of an increment of public funds is sensitive to both the specific type of tax increase and the type of public spending used on the margin best guess assumptions on labor supply elasticities yield marginal costs of public funds for different fiscal mixes of between 0 67 and 4 51 at prevailing tax rates in sweden alternative labor supply assumptions well within the range of current estimates substantially affect the results and can imply infinite marginal welfare costs marginal welfare costs are also sensitive to assumptions about both the income and substitution effects of labor supply

funding transportation spending in metropolitan washington dc the costs of alternative revenue sources abstract this paper develops and implements an analytical framework for estimating the efficiency costs of raising additional revenue from taxes on labor property gasoline peak road use and higher transit fares for the washington dc area the model incorporates driving externalities and interactions between the different policies an economic case can be made for using congestion taxes and possibly gasoline and property taxes to raise extra revenue though it should be qualified for example the inelastic demand for driving limits the congestion benefits per dollar of revenue raised and these taxes have adverse employment effects in the same way that a tax on labor income does

are we consuming too much this paper articulates and applies frameworks for examining whether consumption is excessive we consider two criteria for the possible excessiveness or insufficiency of current consumption one is an intertemporal utility maximization criterion actual current consumption is deemed excessive if it is higher than the level of current consumption on the consumption path that maximizes the present discounted value of utility the other is a sustainability criterion which requires that current consumption be consistent with non declining living standards over time we extend previous theoretical approaches by offering a formula for the sustainability criterion that accounts for population growth and technological change in applying this formula we find that some poor regions of the world are failing to meet the sustainability criterion in these regions genuine wealth per capita is falling as investments in human and manufactured capital are not sufficient to offset the depletion of natural capital

class racial conflict intolerance and distortions in urban form lessons for sustainability from the detroit region in this qualitative analysis into the equity conditions of urban sustainability an examination is presented into the complexity of one particular aspect of intra generational equity racial and class discrimination and its role in distorting urban form and in generating resource inefficient and environmentally destructive human activity patterns the article therefore focuses on the role of discrimination itself in encouraging ecological degradation the detroit region shows that racial and class conflicts can facilitate the shaping of the urban built environment as one population sub group largely white and upper income attempts to distance itself from another sub group that is largely black lower income and considered a threat the outcome is not only disinvestment and decline in the urban core but also excessive suburbanization as whites seek homogenous urban environments and use space to increase the distance between themselves and the black population the study shows that the lack of cooperation and tolerance across ethnic racial and class subgroups facilitates inefficient low density and scattered developments and excessive degradation of natural ecological systems

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

property relations and economic development the other land reform abstract continued concern for development has led to the suggestion that private property rights should be created to stimulate economic development this suggestion derives from an incomplete understanding of the property relations on the public domain lands in the arid tropics and from a confusion of cause and effect between property and economic productivity a model of the private public boundary in land is developed that challenges the view that wealth would increase if land at the extensive margin were privatized the various types of property regimes in land are defined and explained

environmental tax design with endogenous earning abilities with applications to france abstract this paper studies environmental taxation in a mirrlees setting with two novel features first energy a polluting good is used both as a factor of production and a final consumption good second the wage is determined endogenously while labor of different individual types remain homogeneous the model is calibrated for the french economy we show that i the optimal tax is less than the marginal social damage of emissions and turns into an outright subsidy when the inequality aversion index is high ii the optimal tax on energy as an input is always equal to its marginal social damage iii the social welfare gain due to lowering the current energy taxes to their optimal levels with the general income tax being set optimally in both cases is between 17 and 32 euro per household this hurts the rich and benefits the poor

a consumption based approach to environmental kuznets curves using the ecological footprint indicator recent research suggests that consumption based measures offer an insightful perspective on the debate on the relationship between economic growth and the environment in this article we deepen the

international fragmentation boon or bane for domestic employment abstract in this paper we introduce the fairness approach to efficiency wages into a standard model of international fragmentation this gives us a theoretical framework in which wage inequality and unemployment rates are co determined and therefore the public concern can be addressed that international fragmentation and outsourcing to low wage countries lead to domestic job losses we develop a novel diagrammatic tool to illustrate the main labour market effects of international fragmentation we also explore how preferences for fair wages and the size of unemployment benefits govern the employment effects of outsourcing and critically assess the role of political intervention that aims to reduce unemployment benefits under internationally fragmented production

environmental sustainability as the first principle of distributive justice towards an ecological communitarian normative foundation for ecological economics abstract the ecological economic concern with environmental sustainability embodies the normative orientations of the field this concern is foremost a matter of distributive justice the definition of which determines the relevance of the appropriate scale and efficient allocation criteria yet it would appear that the discipline lacks a shared internally consistent set of ethical premises by which this concern might be legitimized various authors have embraced a rawlsian conception of liberal justice as the appropriate banner for ecological economics in place of the consequentialist libertarian foundations of neoclassical economics including environmental economics it is argued here that this is insufficient in so far as it is premised on a vision of a discrete self sufficient economic actor instead it is posited that an ecological economic ethic must proceed from an understanding of the economic actor as community member a recognition implicit in recent ecological economic contributions focused on discourse ethics and deliberative democracy an ecological communitarian conception of distributive justice which views the well being of the individual as inseparable from the integrity of its implicate mutually constituting human and non human natural communities is advanced as the appropriate basis for the ecological economic world view in this light the thermodynamic foundations of ecological economics are seen to provide the necessary departure point for normative decision making oriented towards ensuring sustainability in economic organization

international trade policy in a model of unemployment and wage differentials the author examines the effects of import tariffs and export subsidies in a two sector model with sector specific wage differentials and an equilibrium level of unemployment in general such policies change both the composition and level of employment policies designed to attract workers to the high wage sector could also result in reduced employment and lower social welfare this could happen if the low wage sector is also the relatively labor intensive sector in such situations the optimal policy might entail protecting the low wage labor intensive sector i examine the effects of import tariffs and export subsidies in a two sector model with sector specific wage differentials and an equilibrium level of unemployment in general such policies change both the composition and level of employment policies designed to attract workers to the high wage sector could also result in reduced employment and lower social welfare this could happen if the low wage sector is also the relatively labour intensive sector in such situations the optimal policy might entail protecting the low wage labour intensive sector

redistribution and pollution taxes with non linear engel curves abstract this paper analyses optimal corrective taxation and optimal income redistribution the pigouvian pollution tax is higher if pollution damages disproportionally hurt the poor due to equity weighting of pollution damages moreover under general utility functions optimal pollution taxes should be set below the pigouvian tax if the poor spend a disproportionate fraction of their income on polluting goods however if engel curves are linear optimal pollution taxes should follow the first best rule for the pigouvian corrective tax even if the government wants to redistribute income and the poor spend a disproportional part of their income on polluting goods the often used quasi linear ces and stone geary utility functions all have linear engel curves if engel curves are linear and if pollution taxes are not optimised pareto improving green tax reforms exist that move the pollution tax closer to the pigouvian tax simulations demonstrate that optimal corrective taxes should be pigouvian if the demand for polluting goods is derived from a les demand system but deviate from the pigouvian taxes if demand for polluting goods demand is derived from a piglog demand system

commuting and labour supply revisited according to theory road pricing may reduce welfare when labour supply is negatively distorted by an income tax this effect particularly occurs when commuting costs reduce labour supply we examine the hypothesis that commuting costs reduce labour supply in the short run in particular we estimate the effect of commuting time on labour supply in the uk we account for endogeneity of commuting time by employing exogenous changes in commuting time resulting from firm relocations and changes in infrastructure our results cast doubt on the idea that increases in commuting cost reduce labour supply at least in the short run more precisely we find that females labour supply reacts positively to or is unaffected by increases in commuting time whereas males labour supply is unaffected

transport taxes with multiple trip purposes a congestible urban transport system is considered in which cars and buses are used for commuting and non commuting trips commuting is a strict complement to taxable labour supply the optimal tax structure for raising a given amount of government revenue is examined for the cases where differentiation of transport tolls between trip purposes is and is not possible an application to belgian urban environments shows that optimal toll differentiation produces significant efficiency improvements without differentiation reforming transport taxes generates substantial gains only when the labour tax can be reduced

fairness stewardship and sustainable development abstract the welfare economic concept of fairness offers an attractive axiomatic foundation for the popular notion of stewardship fairness emphasizes the ex ante equal standing of all persons across and within generations this highlights the inextracability of poverty alleviation and environmental sustainability especially in the agrarian tropics where biodiversity loss deforestation and desertification are growing global concerns

intergenerational equity and environmental decisions a model using rawls veil of ignorance abstract four general strategies for resource use exploitationism conservationism naturalist preservationism and extensionist preservationism are sketched and a two step model for deciding resource policy issues is proposed the model based on a modification of rawls hypothetical rational decision model posits a self interested chooser who decides the rules constituting a fair society in the first stage the chooser places pre emptive constraints on each generation s use of resources these constraints embodying leopold s conception of whole ecosystem health limit the options available to individuals of any generation in the pursuit of economic welfare in the second stage each generation may choose a strategy of resource use from those possibilities fulfilling the first stage constraints it is argued that a exploitationism is not in general an acceptable strategy because it violates constraints that would be imposed on all generations by a chooser who is ignorant regarding the generation he will inhabit b extensionist preservation which recognizes values inherent in wild species and natural ecosystems provides no operationalizable guide for environmental policy c conservationism fails to protect the biotic heritage of future generations because applications of the sustainable yield criterion can cause simplification and eventual breakdowns of natural ecosystems and therefore d a broadly naturalist preservationist strategy which imposes constraints on the pervasive exploitation of ecological systems and thereby protects biological diversity in the long run would be chosen by the rational chooser who is ignorant of the generation he will inhabit
