distributional effects of a carbon tax in broader u s fiscal reform abstract this paper analyzes the distributional implications of an illustrative 15 carbon tax imposed in 2010 on carbon in fossil fuels we analyze its incidence across income classes and regions both in isolation and when combined with measures that apply the carbon tax revenue to lowering other distortionary taxes in the economy consistent with earlier findings we find that a carbon tax is regressive using tax swap simulations we then subtract the burden of other taxes the carbon tax revenue could displace and compute the net effect on households under three assumptions about how capital and labor income might be distributed

are emissions permits regressive grandfathered emissions permits redistribute income to wealthy households by creating firm rents that ultimately accrue to shareholders consequently they can be highly regressive even if the poor do not have large budget shares for polluting goods using an analytical model this paper estimates the burden of emissions permits borne by different income groups under control of power plant emissions of carbon so2 and nox we also compare the burden borne by poor households under permits with that under emissions taxes performance standards technology mandates and input taxes and we show how the social costs of policies differ from efficiency costs when society has aversion to inequality

should a carbon tax be differentiated across sectors abstract if some but not all countries are cooperating to reduce co2 emissions one could make the following argument a high carbon tax for carbon intensive tradeable sectors in the cooperating countries will reduce the production of goods from these sectors and therefore co2 emissions in the cooperating countries however this will to a large extent be counteracted by increased production of such goods in the countries that have no climate policy and since it is only total co2 emissions from all countries that are relevant for the climate there is no point in a policy that simply relocates co2 emissions from the cooperating countries to the countries that have no climate policy according to this line of reasoning carbon intensive tradeable sectors should thus face a lower carbon tax than other sectors of the economy this paper shows that a carbon tax should not be differentiated across sectors in the economy provided one can use import and export tariffs on all traded goods it is also shown that such a differentiation of carbon taxes is optimal for the cooperating countries if they are prevented from using tariffs on the traded goods however informational or political factors constraining the use of tariffs are likely also to constrain the possibility of differentiating carbon taxes between sectors

global warming policy a public finance perspective in the last few years a substantial volume of research has considered the design of taxes to slow greenhouse gas emissions as well as the economic effects of such policies in this paper i summarize the insights that have emerged from this work i begin by explaining that while efficiency considerations create a presumption for using coordinated international policies to alter greenhouse gas emissions the prospects for such action are bleak then i focus on the public finance of carbon taxes at the national level considering the design of such taxes as well as their incidence across and within nations next i focus on greenhouse gas emission policies that could be enacted in less developed countries such as the elimination of fossil fuel subsidies and other policies to slow deforestation finally i suggest several promising directions for future study

the distributional incidence of the gasoline tax in chile abstract this paper analyzes the distributional incidence of the excise tax on gasoline in chile using household budget surveys the incidence is calculated with respect to both income and expenditure distributions in order to consider the potential differences between transitory and permanent income the suits index is estimated as a measure of the degree of progressivity of the tax and confidence intervals are calculated using a bootstrap methodology to statistically compare changes in the incidence given changes in the tax the results show that the tax contrary to the evidence for several developed countries is slightly or moderately progressive with a lower degree of progressivity observed in the calculations based on income than those based on expenditure the simulation of the 25 reduction in the tax rate implemented in 2008 shows that in terms of incidence its effect is to reduce the progressivity of the gasoline tax which is the opposite of what was sought by the government with this policy

reforming taxes and raising revenue part of the fiscal solution this paper reviews the fiscal outlook in the united states discusses why revenue increases are a critical aspect of any enduring fiscal solution and outlines constructive policies to reform the tax system and simultaneously raise revenues in particular this paper highlights the merits of curtailing income tax expenditures introducing a value added tax and imposing levies on consumption and production of non renewable energy copyright 2011 oxford university press

taxing consumption and other sins taxes as their primary tools to collect revenue in the rest of the world governments also use income and payroll taxes but rely much more heavily than does the united states on taxing consumption consumption taxes take many forms including general sales taxes value added taxes and excise taxes on the consumption of specific items including gasoline alcohol tobacco products firearms air travel telephone communication and others the u s government does not use a value added tax making the united states unique among high income countries and a rarity in the larger world as of 2004 at least 134 countries rely on value added taxes as a substantial source of funding value added taxes are sophisticated forms of sales taxes in which taxes are withheld by businesses according to value added at every stage of production american states do impose sales taxes on broad categories of consumer purchases but state governments are considerably smaller than national governments and their sales tax rates are very low compared to the value added tax rates used in the rest of the world the united states also imposes unusually low excise taxes even after controlling for total tax collections which are lower in the united states than they are in most high income countries the deliberate social engineering that underlies the selection of certain commodities for unusually high rates of taxation appeals less to americans than to residents of other countries moreover the sin taxes on

replenishment and pricing policy for deteriorating items taking into account the time value of money abstract a deteriorating inventory model taking into account the time value of money is developed for a deterministic inventory system with price dependent demand this study applies the discounted cash flows dcf approach for problem analysis a heuristic approach is presented to derive the near optimal replenishment and pricing policy that tries to maximize the total net present value profit a numerical example is implemented to illustrate the theory

why are households that report the lowest incomes so well off we document that households in the uk with extremely low measured income tend to spend much more than those with merely moderately low income this phenomenon is evident throughout three decades worth of microdata and across different employment states levels of education and marital statuses of the likely explanations we provide several arguments that discount over reporting of expenditure and argue that under reporting of income plays the major role in particular by using a dynamic model of consumption and saving and paying special attention to poverty dynamics we show that consumption smoothing cannot explain all the apparent dissaving

distributional effects of taxing transport fuel this paper1 takes as its starting point the observation that fuel prices and thus taxes are important for good management of climate change and other environmental problems to economists this should be no surprise yet it seems that the role of fuel taxation as an instrument of climate policy has not been fully appreciated it is however one of the few policy instruments that since several decades has actually reduced fuel consumption appreciably thanks to taxation mainly in europe and japan carbon emissions are considerably lower than they would have been otherwise in future where carbon emissions are to be cut drastically this instrument will be crucial there is however much opposition to the instrument this opposition uses various arguments for instance that fuel taxes hurt the poor since they are strongly regressive we however find that the choice of country and methodology turns out to be of great consequence we study seven european countries france germany united kingdom italy serbia spain and sweden and do find some evidence of regressivity but the evidence is very weak it does not apply when lifetime income is used and it does not apply to the poorest country in the group the best one line summary is probably that the tax is approximately proportional

efficient inventory control for imperfect quality items in this paper we present a general eoq model for items that are subject to inspection for imperfect quality each lot that is delivered to the sorting facility undertakes a 100 per cent screening and the percentage of defective items per lot reduces according to a learning curve the generality of the model is viewed as important both from an academic and practitioner perspective the mathematical formulation considers arbitrary functions of time that allow the decision maker to assess the consequences of a diverse range of strategies by employing a single inventory model a rigorous methodology is utilised to show that the solution is a unique and global optimal and a general step by step solution procedure is presented for continuous intra cycle periodic review applications the value of the temperature history and flow time through the supply chain is also used to determine an efficient policy furthermore coordination mechanisms that may affect the supplier and the retailer are explored to improve inventory control at both echelons the paper provides illustrative examples that demonstrate the application of the theoretical model in different settings and lead to the generation of interesting managerial insights

motor vehicle insurance rating with pseudo emissions coverage abstract there is general agreement amongst economists and ecologists that transportation is an important contributor to greenhouse gas emissions typical proposals to reduce the demand for transportation and consequently emissions focus on imposing a fuel tax or a direct fee on vehicles this paper outlines the method and advantages of treating the environmental risk as additional pseudo coverage rated under existing property and liability motor vehicle insurance systems

a distributional analysis of the fairtax plan annual and lifetime income considerations dissatisfaction with the current federal tax system is fostering serious interest in the fairtax plan which would replace most of the federal taxes with a national retail sales tax the fairtax is promoted as being progressive but there is considerable skepticism of this claim we examine the distributional effects of the fairtax as well as the current system it intends to replace under both annual income and lifetime income approaches global measures of progressivity suggest that the current federal tax system is progressive while the fairtax is regressive our results are also robust to different assumptions used for estimation

optimally differentiated carbon prices for unilateral climate policy abstract economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price economists acknowledge that this principle breaks down in a second best world with other distortions such as taxes and market power in domestic and international markets however systematic analysis of this point in the economic climate policy literature is scarce in the present paper a computable general equilibrium cge set up is chosen in order to examine what pattern of differentiated carbon prices emerges as optimal in a second best world the cge model worldscan which is considered to be representative of the class of models routinely used for numerical climate policy analysis produces three main results first the optimal pattern of carbon prices is highly differentiated ranging from almost prohibitive taxes to high subsidies with a range of more than 1700 euros per ton of co 2 second the welfare gain from switching from a uniform price to optimally differentiated prices is enormous equivalent to a 27 emission reduction for free third the most important drivers of carbon price differentiation are market power in export markets as well as taxes on consumption intermediate inputs and domestic output this shows that carbon price differentiation cannot be dismissed as a policy option lightly however before translating these findings into concrete policy advice the relevant features of modelling pre existing distortions in cge models need close revision

economic growth and climate the carbon dioxide problem in contemplating the future course of economic growth in the west scientists are divided between one group crying wolf and another which denies that species existence one persistent concern has been that man s economic activities would reach a scale where the global climate would be significantly affected unlike many of the wolf cries this one in my opinion should be taken very seriously the present article will first give a brief overview of the climatic implications of economic activity with special reference to carbon dioxide and then will present possible strategies for control a more complete report with references to the literature on climatic change is contained in nordhaus 1976 it is thought that the economic activities which most affect climate are agriculture and energy of these the latter is probably more significant is certainly more easily analyzed and will be discussed here in the energy sector emissions of carbon dioxide particulate matter and heat are of significance for the global climate

distributional and efficiency impacts of increased us gasoline taxes we examine the impacts of increased us gasoline taxes in a model that links the markets for new used and scrapped vehicles and recognizes the consider able heterogeneity among households and cars household choice parameters derive from an estimation procedure that integrates individual choices for car ownership and miles traveled we find that each cent per gallon increase in the price of gasoline reduces the equilibrium gasoline consumption by about 0 2

tax incidence when individuals are time inconsistent the case of cigarette excise taxes abstract one of the most cogent criticisms of excise taxes is their regressivity with lower income groups spending a much larger share of their income on goods such as cigarettes than do higher income groups we argue that traditional quantity based measures of incidence are only appropriate under a very restrictive time consistent model of consumption of sin goods a model that is much more consistent with existing evidence on smoking decisions is a time inconsistent formulation where excise taxes on cigarettes serve a self control function that is valued by smokers who would like to quit but cannot this self control function benefits lower income groups more since they have a significantly higher price sensitivity of smoking calibrations show that as a result cigarette taxes are much less regressive than previously assumed and are even progressive for a wide variety of parameter values

tax incidence in differentiated product oligopoly abstract we analyze the incidence of ad valorem and unit excise taxes in an oligopolistic industry with differentiated products and price setting bertrand firms both taxes may be passed on to consumers by more than 100 percent and an increase in the tax rate can increase short run firm profits and hence the long run number of firms we provide summary conditions for these effects to arise the conditions depend on demand curvatures and are written in elasticity form surprisingly the analysis largely corroborates cournot results with homogeneous demand

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

a chinese sky trust distributional impacts of carbon charges and revenue recycling in china abstract the introduction of carbon charges on the use of fossil fuels in china would have a progressive impact on income distribution this outcome which contrasts to the regressive distributional impact found in most studies of carbon charges in industrialized countries is driven primarily by differences between urban and rural expenditure patterns if carbon revenues were recycled on an equal per capita basis via a sky trust the progressive impact would be further enhanced low income mainly rural households would receive more in sky trust dividends than they pay in carbon charges and high income mainly urban households would pay more than they receive in dividends thus a chinese sky trust would contribute to both lower fossil fuel consumption and greater income equality

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

can permanent income theory explain cross sectional consumption patterns the prediction that consumption income ratios should decline as income rises in cross sectional data is a feature of friedman s 1957 permanent income hypothesis and other consumption smoothing models the theory thus provides a link between longitudinal income data and cross sectional expenditure data given measured income variability and a functional relationship between consumption and permanent income we predict cross sectional expenditure patterns and compare those predictions to actual values our approach cannot explain the actual skewness in consumption income ratios under even the strictest consumption smoothing model which implies that income measurement error or other anomalies are affecting the data

the peculiar scale economies of lotto the best selling lottery game in the united states is lotto a parimutuel game of long odds and large jackpots unlike in the other popular lottery games numbers and instant there is a strong tendency for per capita lotto sales to increase with the size of the population base the fact that the jackpot also tends to increase with population size is not a complete explanation since the probability of winning tends to be inversely proportional to state population our explanation for why the games are more successful in large states is that players tend to judge the likelihood of winning based on the frequency with which someone wins then a larger state can offer a game at longer odds but the same perceived probability of winning as a smaller state this abstract was borrowed from another version of this item

is the gasoline tax regressive in the twenty first century taking wealth into account abstract poterba 1991a has much influenced the literature on the distributional effects of carbon pricing poterba argues that the incidence of energy environmental taxes across households is better appreciated if the relative tax burdens are measured against total expenditure interpreted as a proxy for lifetime income instead of annual income this way however since the distribution of total expenditure is structurally more uniform the incidence of energy price increases is always less regressive than when annual income is used this outcome is often taken to lessen the relevance of equity concerns regarding carbon pricing almost twenty five years after poterba 1991a piketty 2014 revived the idea that wealth is a dimension of economic welfare constituting an increasingly important source of inequality we show that omitting wealth in measuring ability to pay means underestimating the regressivity of carbon pricing and its inequity towards younger people using household level data and statistical matching we revisit poterba s application and compare the distributional incidence of the us gasoline tax for different measures of ability to pay total expenditure income and wealth adjusted income regressivity is not a reason to forgo carbon pricing as a cost effective approach to climate mitigation but calls for consideration and compensation of the distributional effects

the implications for households of environmental tax reform etr in europe abstract the paper discusses the distributional implications of environmental tax reform etr for households and presents new results from modelling the impacts of a major etr for the european union the distributional effects arise from the new environmental taxes any tax reductions made as part of the etr the wider macroeconomic impacts from the etr any special provisions in the etr and the environmental benefits from the etr the paper s literature review makes clear that while the impacts from taxes on the household use of energy are very often regressive transport taxes tend not to be although the impacts differ between urban and rural households moreover the net distributional impact is often less regressive or not at all once the wider distributional effects are taken into account residual regressive effects can in principle be removed by further adjustments in the tax or benefits system the modelling results suggest that an etr in europe will actually increase real incomes across the eu as a whole and will not be generally regressive although the results differ by country and for different socio economic groups the political acceptability of etr may depend on the worst effects on these groups being mitigated in some way

the asymmetric relationship between executive earnings management and compensation a panel threshold regression approach abstractprior research shows that chief executive officers ceos are rewarded for their earnings management we re examine this issue using a panel threshold regression approach which allows the effect of earnings management on the ceo compensation to change across the level of earnings management and ceo compensation our results show that the effect of ceos discretionary accounting choices on their compensation is not homogeneous across various degrees of earnings management and compensation in particular for firms with moderate inordinate levels of earnings management and ceo compensation earnings management is rewarded penalized

estimating tax incidence market power and market conduct the european cigarette industry abstract recent theoretical work has shown that the incidence of ad valorem and specific taxes may differ and each may be over or under shifted onto consumers in the presence of imperfect competition these results are used to derive a method of estimating market power and conduct an application is made to the european cigarette industry previous empirical comparison of the incidence of ad valorem and specific taxes is limited for a group of countries with broadly similar cigarette industries there is evidence of undershifting of both taxes with the specific tax having a significantly greater impact on price the extremes of both perfect competition and monopoly can be rejected behaviour is no less competitive than the equivalent of cournot

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

debt covenant violation and manipulation of accruals abstract this paper examines the abnormal accruals of a sample of 94 firms that reported debt covenant violations in annual reports we expect debt covenant restrictions to influence accounting choices in the year preceding and the year of violation time series and cross sectional models are used to estimate normal accruals in the year prior to violation both models indicate that abnormal total and working capital accruals are significantly positive in the year of violation there is evidence of positive abnormal working capital accruals after controlling for management changes and auditor going concern qualifications

energy and climate hand in hand financing res e support with carbon revenues abstract in italy the cost of support for renewable electricity res e is largely recovered through the a3 surcharge which weighs heavily on electricity bills using household survey data we show the a3 surcharge is markedly regressive carbon taxation in the non ets sector is envisaged as a means to reduce co2 emissions cost effectively and generate revenue to lower the a3 surcharge a non ets carbon tax would be less regressive than the a3 surcharge and its cost would be more evenly distributed across households we calculate the revenue of a 20 tco2 non ets carbon tax would have allowed a cut in the a3 surcharge of about 68 in 2011 and 39 in 2012 the impact of the carbon tax plus the reduced a3 surcharge would have been less regressive but the cost higher for most households the restrictions imposed in the simulations mean the results are only appropriate to render first round effects of the reform policy relevance in the vast majority of the eu member states the cost of res e support is largely paid by electricity consumers most often through specific surcharges rising electricity prices are a common concern given the implications for competitiveness and equity the member states facing this issue could conveniently address it through environmental tax reforms consistent with the climate and energy package replacing res e surcharges with carbon taxes in the non ets sector would permit cost effective reduction of co2 emissions while allocating the cost of res e support more equitably the difference in regressivity would stem from the different consumption patterns of home fuels including electricity and motor fuels across income distribution a cross country comparison of energy household budget shares proves the structural nature of this difference between home fuels and motor fuels moreover the notion that electricity consumers should pay for res e support is questioned on the grounds that electricity is a basic necessity good and res e support is a means of providing public goods notably energy security and climate protection

lifetime versus annual tax and transfer progressivity sweden 1968 2009 in this paper we analyze the evolution of tax and transfer progressivity in sweden over both annual and lifetime horizons using a rich micro panel covering the period 1968 2009 we calculate tax rates over a cohort s entire working life cycle our main finding is that taxes are considerably less progressive over the lifetime than in any single year social insurance transfers to transitory low income earners account for most of this result we offer a number of robustness checks of the measurement of lifetime incomes and progressivity but none of them changes our overall findings

economic inequality and the value of nature abstract understanding what influences the value of nature is crucial for informing environmental policy from a sustainability perspective economic valuation should not only seek to determine a society s willingness to pay for environmental goods to devise an efficient allocation of scarce resources but should also account for distributional effects to ensure justice yet how economic inequality affects the value of non market environmental goods remains understudied combining recently developed theoretical results with empirical evidence this commentary shows that more equal societies have a higher valuation for environmental public goods and that non market benefits of environmental policy accrue over proportionally to poorer households on this ground we discuss implications for environmental valuation management and policy making and identify a number of fruitful areas for future research we conclude that environmental valuation should explicitly account for economic inequality and that encompassing assessments of the distributional effects of environmental policies must consider the distribution of non market environmental benefits

carbon taxes with exemptions in an open economy a general equilibrium analysis of the german tax initiative abstract sectoral exemptions from environmental regulation are applied in many countries to avoid adverse adjustment effects in specific industries the problem with exemptions is that they can make environmental policy more costly our paper analyzes the welfare costs of exemptions in environmental policy together with the issue of unilateral carbon taxes in an open economy several countries within the eu have introduced or contemplated unilateral taxes to reduce anthropogenic co2emissions taxes which are unilaterally imposed in an open economy can have significant impacts on production and employment of energy and export intensive industries to save jobs by maintaining international competitiveness most co2taxation schemes include exemptions for energy and export intensive industries as a compromise between environmental objectives and employment in these sectors this paper shows that such compromises are costly as the tax base narrows the dead weight loss increases our calculations illustrate this point in the framework of a static general equilibrium model for west germany calibrated to 1990 data we evaluate the excess costs of exemptions as a means of saving jobs in specific industries relative to an alternative instrument a uniform carbon tax cum wage subsidy which achieves an identical level of national emissions and employment at a fraction of the cost

long run gasoline demand for passenger cars the role of income distribution it is commonly agreed that the level of income and prices are crucial determinants of the consumption of motor gasoline the respective long run price and income elasticities are regularly calculated using cross sectional models despite the acknowledgement of the role of income distribution it plays no role in intercountry cross sectional models this is due to a lack of appropriate data this paper shows that the omission of distributional characteristics provides misleading elasticities using available distributional measures this paper is referring to an income threshold which is crucial to the acquisition of an automobile it is shown that on the one hand in poor countries an unequal income distribution is needed to enable at least some people to buy automobiles on the other hand in wealthy countries an unequal income distribution would exclude some people from acquiring automobiles hence depending on the income level inequality has a diverging impact on the ability to buy durable goods the second part of this paper develops a pooled 90 country model to examine this approach empirically it could be shown that distribution variables are highly significant to explain the demand for automobiles and motor gasoline moreover the consideration of the distribution of income leads to a considerable decrease in income elasticity values this is mainly due to the positive correlation between income level and income equality within the sample

discounted costs obsolescence and planned stockouts with the eoq formula abstract in this paper we propose a simple economic order quantity for a class of inventory management problems concerning items with a short and stochastic lifetime the analysis is relevant to the management of items in industries subject to fast technological progress where the obsolescence rate is large the approach is performed in the framework of the total discounted cost criterion a new economic order quantity is computed it may turn out to be significantly smaller than the one given by wilson formula finally we show that a policy maker who faces the risk of obsolescence can plan stockouts if sufficiently many customers accept late delivery

estimating price elasticities when there is smuggling the sensitivity of smoking to price in canada a central parameter for evaluating tax policies is the price elasticity of demand for cigarettes but in many countries this parameter is difficult to estimate reliably due to widespread smuggling which significantly biases estimates using legal sales data an excellent example is canada where widespread smuggling in the early 1990s in response to large tax increases biases upwards the response of legal cigarette sales to price we surmount this problem through two approaches excluding the provinces and years where smuggling was greatest and using household level expenditure data on smoking these two approaches yield a tightly estimated elasticity in the range of 0 45 to 0 47 we also show that the sensitivity of smoking to price is much larger among lower income canadians in the context of recent behavioral models of smoking whereby higher taxes reduce unwanted smoking among price sensitive populations this finding suggests that cigarette taxes may not be as regressive as previously suggested finally we show that price increases on cigarettes do not increase and may actually decrease consumption of alcohol as a result smuggling of cigarettes may have raised consumption of alcohol as well

pollution taxes and revenue recycling abstract discussions of environmental policy and the tax system have emphasized the value of pollution tax revenues which can be used to reduce other tax distortions in the economy however by raising private marginal production costs environmental taxes also tend to reduce gdp and exacerbate the welfare costs of conventional taxes for environmental taxes in consumption goods industries the net welfare change from these two effects is negative unless this good is a relatively weak substitute for leisure an estimate for the optimal pollution tax with full revenue recycling is 63 to 78 of marginal environmental damages

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

distributional impacts of carbon pricing a general equilibrium approach with micro data for households article i nfo many policies to limit greenhouse gas emissions have at their core efforts to put a price on carbon emissions carbon pricing impacts households both by raising the cost of carbon intensive products and by changing factor prices a complete analysis requires taking both effects into account the impact of carbon pricing is determined by heterogeneity in household spending patterns across income groups as well as heterogeneity in factor income patterns across income groups it is also affected by precise formulation of the policy how is the revenue from carbon pricing distributed as well as the treatment of other government policies e g the treatment of transfer payments what is often neglected in analyses of policy is the heterogeneity of impacts across households even within income or regional groups in this paper we incorporate 15 588 households from the u s consumer and expenditure survey data as individual agents in a comparative static general equilibrium framework these households are represented within the mit usrep model a detailed general equilibrium model of the u s economy in particular we categorize households by full household income factor income as well as transfer income and apply various measures of lifetime income to distinguish households that are temporarily low income e g retired households drawing down their financial assets from permanently low income households we also provide detailed within group distributional measures of burden impacts from various policy scenarios

true world income distribution 1988 and 1993 first calculation based on household surveys alone the paper derives world income or expenditure distribution of individuals for two years 1988 and 1993 it is the first paper to calculate world distribution for individuals based entirely on household survey data from 91 countries and adjusted for differences in purchasing power parity between the countries measured by the gini index inequality increased from an already very high 63 in 1988 to 66 in 1993 the increase was driven more by rising differences in mean incomes between the countries than by rising inequalities within countries the most important contributors were rising urban rural differences in china and slow growth of rural incomes in south asia compared to several large developed market economies

a century of evolution from harris s basic lot size model survey and research agenda abstract determining the economic lot size has always represented one of the most important issues in production planning this problem has long attracted the attention of researchers and several models have been developed to meet requirements at minimum cost in this paper we explore and discuss the evolution of these models during one hundred years of history starting from the basic model developed by harris in 1913 up to today following harris s work a number of researchers have devised extensions that incorporate additional considerations the evolution of eoq theory strongly reflects the development of industrial systems over the past century here we outline all the research areas faced in the past by conducting a holistic analysis of 219 selected journal papers and trying to give a comprehensive view of past work on the eoq problem finally a new research agenda is proposed and discussed

efficiency and equity in two part tariffs the case of residential water rates as first noticed by coase 1946 a standard result in utility regulation is that efficiency requires two part tariffs with marginal prices set to marginal costs and fixed fees equal to each customer s share of fixed costs residential water customers in france face marginal prices for water that average about 8 more than marginal costs under price elasticity estimates that are consistent with previous results in the literature efficiency costs represent around 8 million euros of welfare losses for 2008 even though the impact is fairly small current price schedules are an important pre existing distortion which should be considered when evaluating current taxes aimed at addressing external costs moreover efficiency gains from reformed tariffs could be used to fund water assistance programs focused on financially stressed households

are the costs of reducing greenhouse gases from passenger vehicles negative energy models suggest that the costs of reducing carbon emissions from transportation are high relative to those for other sectors this paper discusses why taxes or equivalent permit systems to reduce passenger vehicle emissions produce large net benefits rather than costs when account is taken of a their impact on reducing other highway externalities besides carbon and b interactions with the broader fiscal system both of these considerations also strengthen the case for a tax based approach over fuel economy regulation while fiscal considerations strengthen the case for taxes over grandfathered emissions permits the paper also comments on the practical relevance of automobile fuel taxes or their policy equivalents to broader legislation intended to mitigate climate change

a tale of two tails commuting and the fuel price response in driving abstract pricing greenhouse gases is widely understood as the most efficient approach for mitigating climate change yet distributional effects hamper political acceptance these distributional effects are especially important in transport the fastest growing sector for greenhouse gas emissions using rich data covering the entire population of vehicles and households in denmark this study uncovers an important feature of driving demand two groups of much more responsive households in the lower and upper tails of the work distance distribution we further estimate the causal effect of public transport a critical determinant of the upper tail and show how public transport access can both reconcile differences in fuel price elasticities between the united states and europe and considerably influence the distributional effects of fuel pricing

tax policy issues in designing a carbon tax a carbon tax is a promising tool for discour aging the greenhouse gas emissions that cause climate change in principle a well designed tax could reduce the risk of climate change minimize the cost of emissions reductions encourage innovation in low carbon technologies and raise new public revenue but designing a real world carbon tax poses significant challenges we analyze those challenges from a public finance perspective emphasizing three tax policy design issues setting the tax rate collecting the tax and using the resulting revenue the benefits of a carbon tax will depend on how policymakers address those issues

the economics of casino taxation in this article a model of the costs of a casino is developed that focuses on the implications for economic welfare of different taxation schemes for casinos the situation being considered is in a country where casinos cater exclusively to foreign tourists the goal of the country is to determine the maximum amount of taxes that can be extracted from the activities of this sector under different systems of taxation when the price of gambling is set by regulation above its competitive level the economic losses created by excessive investment in the sector can be reduced by taxation a turnover tax on the amount gambled can maximize both tax revenue and the economic welfare of the country due to administrative constraints a number of countries rely on the taxation of the casinos fixed assets or a combination of a turnover tax and a tax on fixed costs the model is applied to the situation in north cyprus the annual economic efficiency loss from its poorly designed tax policies on casino gambling is

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

economic lot sizing with learning and continuous time discounting is it significant abstract learning curves are a means of representing continuous improvement in firms such improvements bring savings in production costs this may also allow smaller batches to be produced more frequently and hence bring further savings in holding costs earlier research advocated that for more realistic modelling of inventory problems the holding cost should be evaluated means of the internal discount rate of the firm c van deft j p vail international journal of production economics 44 1996 255 265 this paper examines whether when learning is considered it is reasonable to ignore the effect of continuous time discounting of costs by investigating the effect of learning and time discounting both on the economic manufacturing quantity and minimum total inventory cost numerical examples are provided to illustrate the solution procedure for the mathematical model developed although the analysis yields different economic order quantities the difference in cost from the quantities derived using wilson lot size formula is not significant

the equity and efficiency of two part tariffs in u s natural gas markets abstractresidential natural gas customers in the united states face volumetric charges that average about 30 percent more than the marginal cost of gas this inefficient departure from marginal cost pricing allows gas utilities to cover their fixed infrastructure and operating costs proposals for recovering these costs instead through fixed monthly fees are often opposed because of a widespread belief that current rate schedules have desirable distributional consequences using nationally representative household level data we show that the correlation between household income and natural gas consumption is indeed positive but surprisingly weak so current rate schedules are only mildly progressive in part we argue that this is because poor households tend to have larger families and less energy efficient homes we calculate bill impacts under a variety of scenarios and show that even a modest energy assistance program would more than offset the distributional impact of tariff rebalancing for most low

the distributional implications of a carbon tax in ireland we study the effects of carbon tax and revenue recycling across the income distribution in the republic of ireland in absolute terms a carbon tax of 20 tco2 would cost the poorest households less than 3 week and the richest households more than 4 week a carbon tax is regressive therefore however if the tax revenue is used to increase social benefits and tax credits households across the income distribution can be made better off without exhausting the total carbon tax revenue

lifetime incidence and the distributional burden of excise taxes this implies that low income households in one year have some chance of being higher income households in other years and significantly affects the estimated distributional burden of excise taxes this paper shows that household expenditures on gasoline alcohol and tobacco as a share of total consumption a proxy for lifetime income are much more equally distributed than expenditures as a share of annual income from a longer horizon perspective excise taxes on these goods are therefore much less regressive than standard analyses suggest this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

the incidence of fuel taxation in india abstract fuel taxes have returned to centre stage as a potential policy instrument for greenhouse gas abatement on the basis of some studies in developed countries critics have complained that a fuel tax would be regressive this paper uses data from a representative household survey covering more than 124 thousand indian households to examine this claim it finds that a fuel tax would be progressive as would a carbon tax using an input output approach it is found that the progressivity results holds good even when one considers indirect consumption of fuel through its use as an intermediate input sensitivity checks allowing for differing price elasticities of demand between rich and poor confirm this result for most of fuels a tax on kerosene is the only fuel tax that is regressive in all situations

measurement of inequality by components of farm household consumption expenditures inequality in consumption levels of families both nationally and internationally has been studied by theil however empirical studies that measure inequality in farm household consumption to our knowledge have not been performed this study measures inequality in farm household consumption in addition the study also measures inequality in consumption based on farm typology and farming region results from this analysis show consumption inequality among farm households is lower than consumption inequality among all other households results indicate that other expenditures component has the highest inequality and food and household supplies component has the lowest inequality further farm typology has information about difference in consumption expenditures the typology is informative when it comes to the components of consumption while the regional decomposition is not

the impact of a carbon tax on inequality abstract climate change and economic inequality are inextricably linked despite widespread agreement among researchers and policymakers that a carbon tax is the most efficient mechanism to curb greenhouse gas emissions such a tax exacerbates inequality since low income households spend a greater share of their income on carbon intensive goods using input output tables and detailed expenditure data for the united states we estimate households carbon footprints and examine the impact of a revenue neutral tax of 50 per ton of co2 on multiple forms of inequality devoting carbon tax revenue to fund a carbon dividend makes the policy progressive minimizes redistribution among households of similar means mitigates group based inequalities and benefits 56 of people including 84 in the bottom half of the distribution while some researchers have dismissed dividends on efficiency grounds we show that the double dividend typically associated with labor tax cuts is insufficient to protect the purchasing power of a majority of americans

the taxation of the poor this paper uses microsimulation modeling to estimate the annual burden offederal state and local taxes on the poor in two states we find that in 1988 the average burden of taxation on poorfamilies and individuals was 15 3 percent in massachusetts and 18 percent in new york as most of the burden is due to state and local taxes federal tax reform had only a minor impact on the overall tax burdens faced by the poor though the analysis is for two state we argue that the basic results are applicable for most other states given the high incidence of persistent poverty among those who are poor in any given year we argue that annual burdens provide a good indication of long run burden for a significant proportion of the poor

can carbon taxes be progressive abstract most studies have assessed the distributional impact of carbon taxes through their effects on commodity prices alone while ignoring their impact on individual welfare brought about by changes in factor prices yet the remunerations of capital and labor are not affected by these taxes similarly and their shares in earned incomes are not uniform across households this paper provides a comprehensive analysis of the incidence of carbon taxes on inequality by considering simultaneously the commodity and the income channels we propose a decomposition of the change in individual welfare metrics then we develop a general equilibrium model to assess the impact of carbon taxes on factor and commodity prices and subsequently their distributional impact on households using the lorenz and concentration curves and the gini index our results suggest that changes in factor prices and changes in commodity prices especially those of energy commodities have opposing effects on inequality carbon taxes tend to reduce inequality through the changes in factor prices and tend to increase inequality through the changes in commodity prices hence we find a non monotonic u shaped relationship between carbon taxes and inequality our results suggest that the traditional approach of assessing the impact of carbon taxes on inequality through changes in commodity prices alone may be misleading the findings cast light on the desirability of using both channels in the assessment of carbon taxes on inequality

what is a fair co2 tax increase on fair emission reductions in the transport sector we examine how individual preferences for fair reductions of carbon dioxide co2 emissions affect the support for increases in the co2 tax on gasoline and diesel we assume that people not only care about their own material welfare but also have preferences for fairness in policy design and we explore the implications using original data from a mail questionnaire sent to a representative sample of the swedish population the main result is that fairness in policy design does matter those respondents who adhere to a fairness principle tend to be relatively more positive to increases in the co2 tax one possible explanation for this result is that there is a relatively high degree of reciprocity regarding the origin of emissions and the fairness regarding who should bear the burden of co2 reductions via a split sample analysis we also find that the relative importance of fairness principles is dependent upon whether one uses a car often or not this sheds light on the potential goal conflict between the importance of fairness principles and self interest in the form of a need for private car transportation

exploring the impact of internal corporate governance on the relation between disclosure quality and earnings management in the uk listed companies this study investigates the impact of internal corporate governance on the relation between disclosure quality and earnings management in the uk listed companies in particular whether governance mechanisms have deterrent effect on earnings management similar to firms disclosure quality unlike prior literature we measure a number of board and audit committee related governance instruments three disclosure quality proxies i e investor relation magazine award forward looking disclosure and analyst forecast accuracy and the modified jones model to test the hypotheses of the study on a matched pair sample data of investor relation magazine award winning and non winning firms our findings in the ols and sensitivity analyses using heckman procedure and 2sls regressions consistently report a significant negative association between earnings management and disclosure quality for all proxies in restraining earnings management in contrast corporate governance variables are mostly insignificantly related to earnings management this provides an emerging trend of the outperformance of disclosure quality over internal governance mechanisms in lessening earnings management these findings warrant due attention of the policy makers investors corporate firms and other stakeholders in shaping a high quality disclosure and governance regime in corporate settings to mitigate managerial manipulations of earnings across the countries in the world

automobile externalities and policies this paper discusses the nature and magnitude of externalities associated with automobile use including local and global pollution oil dependence traffic congestion and traffic accidents it then discusses current federal policies affecting these externalities including fuel taxes fuel economy and emissions standards and alternative fuel policies summarizing insofar as possible the welfare effects of those policies finally we discuss emerging pricing policies including congestion tolls and insurance reform and summarize the appropriate combination of policies to address automobile externalities

investor sophistication and market earnings expectations this paper investigates whether sophisticated investors rely more on analyst forecasts than on time series model forecasts in forming expected earnings although analyst forecasts are generally more accurate than time series model forecasts e g o brien 1988 analyst forecasts are not clearly superior to time series model forecasts as a proxy for expected earnings e g brown et al 1987b recent research has concluded that earnings expectations reflected in stock prices at least partially reflect a seasonal random walk srw model bernard and thomas 1990 and abarbanell and bernard 1992 in particular ball and bartov 1996 find that market earnings expectations incorporate the sign of the serial correlation in seasonally differenced earnings but underestimate the correlation magnitude see also maines and hand 1996 these findings suggest that at least some market participants ignore public information in forming expected earnings i examine whether information usage is correlated with investor sophistication and or the degree to which investors are informed

accruals management investor sophistication and equity valuation evidence from 10 q filings the release of the full set of financial statements in form 10 q provides investors with the data necessary to estimate the discretionary portion of earnings thereby allowing them to better assess the integrity of reported quarterly earnings we thus expect a negative association between unexpected discretionary accruals estimated using 10 q disclosures and stock returns around 10 q filing dates consistent with our expectations we document a negative association between unexpected discretionary accruals and cumulative abnormal returns over a short window around the 10 q filing date furthermore this association varies systematically with investor sophistication finally results from portfolio tests indicate that this association is economically as well as statistically significant one interpretation of our findings is that accruals management has substantial valuation consequences which are quickly impounded into stock prices

the welfare effects and the distributive impact of carbon taxation on italian households in this work the welfare effects and the distributive impact on italian households of the italian carbon tax are calculated the carbon tax has been introduced in italy at the beginning of 1999 asking for smooth increases over a number of years in the prices of most fossil fuels its welfare effects have been calculated using true cost of living index numbers and the compensating variation the parameters have been obtained through estimation of a complete almost ideal demand system using households data from 1985 to 1996 the welfare loss turns out to be quite substantial and affects italian households in a non negligible way but the distribution of welfare losses across different levels of total monthly expenditures does not allow sustaining the regressivity of carbon taxation as the effect becomes bigger as we move up the income distribution this evidence might encourage the use of carbon taxes at least in the transport sector as cost effective instruments of environmental policy especially after the ratification of the kyoto protocol on climate change

market structure and casino taxation in tourist resorts this article examines the association of tax effects with market structure for casino gaming we show that if market structure is uncompetitive much of casino taxation falls on tourists whose demand is inelastic relative to supply the tax is likely to be efficient under strong external demand if imposed on oligopoly casinos with a monopoly location in a cross border market the likelihood of economically good taxation is greater under oligopoly than under competition but lower than under monopoly casino taxes should be lowered in a more competitive market with weaker external demand our prediction is consistent with the evidence found from casino tourism development in macao with high gambling taxes

fair value pension accounting abstract we compare the value and credit relevance of financial statements under fair value and smoothing sfas 87 models of pension accounting while fair value improves the credit relevance of the balance sheet it does not improve its value relevance further fair value impairs both the value and credit relevance of the income statement and the combined financial statements unless transitory gains and losses g l are separated from more persistent income components overall our results suggest there are no informational benefits to adopting a fair value pension accounting model
