how do market reforms affect china s responsiveness to environmental policy a large percentage of total investment in china is allocated by the central government at below market interest rates in pursuit of non economic objectives this has resulted in low rates of return and a high number of non performing loans threatening the future health of the chinese economy as a result reform of capital markets is a high priority of the chinese government at the same time the country is implementing various environmental policies to deal with serious pollution issues in this paper we ask how reforms of the capital market will affect the functioning of a carbon tax this allows us to assess how china s willingness to join global efforts to reduce carbon emissions is influenced by china s current efforts to reduce investment subsidies we compare the costs of a carbon tax in a reformed economy with the costs of a carbon tax in the current subsidized economy we find that in the subsidized economy the tax interaction effect dampens the effect of a carbon tax resulting in smaller reductions in emissions than what would result in a reformed economy importantly we also find that the effect on economic welfare from a carbon tax is lower in the subsidized economy in fact for lower levels of reductions the carbon tax is actually welfare improving these results have important implications for an economy undergoing economic transition the carbon tax rate required to achieve a certain level of emission reductions will be higher in an economy with capital subsidies however the welfare implications of the tax indicate that the current system with capital subsidies is highly distorting implying that there is a high efficiency cost for the non economic objectives the government is pursuing by maintaining this system of subsidies

are environmental taxes a free lunch issues in modelling the macroeconomic effects of carbon taxes applied analysis of output and employment effects from revenue neutral environmental taxation depends critically on how the supply side of the economy is modelled despite the long history of theoretical and computable general equilibrium supply side models the empirical basis of much of this work has been quite weak until recently however most econometric attempts to capture factor substitution effects have not been based on theoretically consistent structures this paper examines the methodological issues that underlie these problems and compares the results of imposing environmental taxes in two different econometric modelling structures the implications of theories of endogenous technical progress on the simulation properties of such models are discussed and a simple empirically based model that embodies some of these features is presented

on cost benefit rules for green taxes this paper concerns the welfare effects of a green tax reform in a dynamic general equilibrium model with preexisting taxes on labor income and capital income in comparison with previous studies on green taxes in dynamic models which have focused their main attention on long run effects of such reforms i derive cost benefit rules for a change in the tax mix by using the properties of the value function in optimal control theory this enables me to relate the welfare effect of a change in the tax mix to responses in employment the capital stock flow emissions and the stock of pollution along the whole general equilibrium path another contribution of the paper is to examine under what conditions an emission tax which is set permanently below the marginal damage of pollution is welfare superior to an emission tax path that fully internalizes the external effect

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

housing finance and urban infrastructure finance financing issues received major attention in the discussions of human settlement development policy through the preparatory process for habitat ii and at the conference itself this paper presents

commuting transport tax reform and the labour market employer paid parking and the relative efficiency of revenue recycling instruments in this paper the welfare effects of a budget neutral increase in taxes on car commuters are studied in a model that takes into account the presence of employer paid parking at the workplace it is found that the presence of employer paid parking substantially increases the welfare effect of such a tax reform independent of the use of the revenues congestion taxes not only correct congestion externalities they also reduce the inefficiency caused by employer paid parking moreover different congestion effects of alternative recycling instruments and the presence of employer paid parking jointly imply that recycling the tax revenues via higher public transport subsidies may yield much more favourable welfare effects than previously believed it can easily outperform recycling the tax revenues via lower labour taxes finally cashing out parking costs to public transport users is found to generate substantial positive welfare effects numerical analysis confirms the theory

optimal taxation and cross price effects on labor supply estimates of the optimal gas tax abstract this study estimates parameters necessary to calculate the optimal second best gasoline tax most notably the cross price elasticity between gasoline and leisure prior theoretical work indicates the importance of this elasticity but despite this almost none of the prior studies of commodity taxation and none of the studies on second best environmental regulation actually estimate it using household data we find that gasoline is a relative complement to leisure and thus that the optimal gasoline tax is significantly higher than marginal damages the opposite of the result suggested by the bulk of the prior literature indeed even if there were no externalities at all associated with gasoline the optimal tax rate would still be almost equal to the average gas tax rate in the u s following this approach to estimate cross price elasticities with leisure could strongly influence estimates of optimal rates for other important commodity or pollution taxes

socialist cities without land markets abstract how does the spatial dynamics of the socialist city compare with that of the market city what happens when all investment decisions are made administratively in the absence of land markets russian development is the longest socialist experiment on record its outcome is of paramount interest to urban economists this paper reports the first analysis of the structure of russian cities after 70 years of soviet development the main finding is a perversely positive population density gradient the soviet city also has a disproportionate share of industrial land often in prime locations free property trading started in russia in 1992 the emerging negative price gradient contrasts totally with the positive population gradient that is the legacy of administrative land allocation these two conflicting gradients highlight the land misallocation and inefficiency of the socialist city

second best taxation of emissions and polluting goods abstract this paper studies the problem of the design of an integrated system of second best emission and output taxes in a model where production costs are negatively correlated with their emissions it shows that i the first best pigouvian rule of equating the marginal private benefit of emissions in production to the marginal social damage of emissions must be modified in the second best ii implementation of the modified pigouvian rule requires all firms to face the same marginal emission tax equal to the marginal social damage of emissions plus an adjustment term reflecting optimal tax objectives iii it may not be necessary to directly tax the polluting goods the latter taxes can be subsumed in the emission tax function iv output taxes must be set solely on the basis of optimal tax objectives no pigouvian adjustment is required v if emission taxes are restricted to be proportional and commodity taxes are constrained the modified pigouvian rule will no longer be optimal vi if preferences are weakly separable in emissions and other goods the pigouvian rule remains valid the marginal emission tax is pigouvian and emission and commodity tax instruments can be set separately to address different objectives a proportional emission tax corrects for externalities while commodity taxes are determined solely on the basis of optimal tax considerations

comment on m hoel emission taxes versus other environmental policies the choice of the appropriate instrument in environmental policy is not only a question of theoretical importance it is also of considerable political relevance while environmental taxes are sometimes used to control pollution quotas and direct controls dominate in practice if this observed bias is only due to the nature of policymaking and not supported by economic reasoning politicians are not well advised to use quotas and direct controls instead of environmental taxes hoel discusses popular arguments that are often used by politicians in favour of direct controls and concludes that the results are typically not clear cut in this comment i would like to focus on the employment effects of revenue raising and nonrevenue raising instruments politicians as well as special interest groups often claim that emission taxes increase the cost of production thereby harming employment clearly in the face of high rates of unemployment in many industrialized countries potentially negative employment effects of environmental regulation raise political resistance to green policy the ongoing debate has put

the double dividend second best worlds and real world environmental policy abstract the recent series of papers by bovemberg goulder parry and others argue that the double dividend is unlikely to exist because of second best problems they argue that the imposition of environmental tax in an economy already distorted by income taxes will further distort the economy by reducing incentives to supply labor our paper argues that this is not likely to be the case because of the restrictive assumptions made by these models and because of the role of the environment as a factor of production

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

environmental taxation and unemployment some evidence on the double dividend hypothesis in europe abstract the employment double dividend hypothesis suggests that an appropriately designed fiscal reform in which emission charges are used to subsidize employers social security contributions may realize at least two relevant policy goals a better quality of the environment and at the same time an increase in employment levels this paper uses a newly developed econometric general equilibrium model for the european union as well as for each member country and presents simulation results up to the year 2010 of the effects of a european carbon tax the revenues from which are recycled to reduce employers social security contributions the results show that recycling carbon tax revenues may provide an employment double dividend only in the short run

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

pollution taxation and revenue recycling under monopoly unions a model where a given number of firms determine their pollution reducing production technologies upon establishment and workers form monopoly unions is used to study the possibility of double dividends i e simultaneous reductions in pollution and increases in employment when the pollution tax is increased and tax revenues recycled in alternative ways in all cases pollution is reduced when output is subsidized the effect of a pollution tax increase on employment is always neutral when employment and investments are subsidized employment increases when investments are respectively relatively insensitive and sensitive to pollution taxes of the three subsidy instruments the employment subsidy is always the most and the investment subsidy the least efficient solution

an integration of trade union models in a sequential bargaining framework this paper aims to embed two popular models of trade union behavior the monopoly model and the efficient bargaining model in a more general framework it does this by analyzing sequential bargaining models where wages are determined before employment and the power of the union in the two stages of the bargain differs as well as finding that the monopoly and efficient bargain models are special cases of this model a new class of models is also discovered this framework is used to analyze the relationship between union pow er and efficiency the empirical analysis of trade unions and the effects of trade union legislation copyright 1987 by royal economic society

optimal gasoline tax in developing oil producing countries the case of mexico this paper uses the methodology of parry and small 2005 to estimate the optimal gasoline tax for a less developed oil producing country the relevance of the estimation relies on the differences between less developed countries ldcs and industrial countries we argue that lawless roads general subsidies on gasoline poor mass transportation systems older vehicle fleets and unregulated city growth make the tax rates in ldcs differ substantially from the rates in the developed world we find that the optimal gasoline tax is 1 90 per gallon at 2011 prices and show that the estimate differences are in line with the factors hypothesized in contrast to the existing literature on industrial countries we show that the relative gasoline tax incidence may be progressive in mexico and more generally in ldcs

efficient wage bargaining as a repeated game this paper builds a bridge between the two existing approaches for wage and employment determination in a unionized market the monopoly union model and the efficient bargaining model both fail to capture the dynamic aspects of wage bargaining when the repeated nature of the wage bargaining process is considered the equilibria are neither as inefficient as the monopoly union model predicts nor as fully efficient rather the two models can be regarded as particular cases with certain discount rates we apply our model to issues such as the endgame interpretation of the u s steel industry wage concessions and featherbedding

environmental policy tax incidence and the cost of public funds this paper studies under what conditions a double dividend may occur in the sense that both environmental quality and employment rise a simple static general equilibrium model is employed in which tax policy faces the dual task of internalising a negative environmental externality and raising revenue to finance public consumption the model features a clearing labour market with both labour demand and supply and a fixed factor of production e g capital hence we can study tax incidence and its effect on employment environmental quality and the marginal cost of public funds it is shown for the case of an upward sloping labour supply curve and less than full tax shifting by employers that a shift towards greener preferences cannot yield a double dividend even if the fixed factor is important however if labour supply curve bends backwards more environmental concern confers a double dividend

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

optimal differentiation of international environmental taxes in the presence of national labor market distortions we explore the implication of the doubledividend debate for international environmentaltaxes in our scenario small open economies withdifferent labor market distortions follow a commonenvironmental policy and use national environmentaltax revenues to finance labor tax cuts since thedouble dividend hypothesis does not hold a high labortax implies a low environmental tax relative to othercountries the optimal differentiation ofinternational environmental taxes is proven to be afunction of the national labor tax rates and theuncompensated elasticities of labor supply

choosing the right instrument the role of public revenues for environmental policy this paper analyses the optimal choice of second best optimal environmental policies using a partial equilibrium model the paper first reconfirms the well known result that the existence of a double dividend in its weak definition favours environmental policy instruments which maximise tax revenues for a given improvement in environmental quality additional revenues can be used to reduce the distortion of existing taxes such as taxes on labour and capital income without uncertainty environmental taxes and auctioned permits are equally appropriate in the presence of uncertainty however the optimal choice of taxes or tradable permits depends on the relative magnitudes of the marginal environmental damage and the marginal benefit from consuming a polluting good in the second part the paper therefore analyses how the revenue capacity affects the optimal choice of environmental policy instruments in the presence of uncertainty the paper shows that the first best choice rule between price and quantity regulation weitzman 1974 remains valid in a second best world with distortionary taxation

analysis of urban land shortages the case of korean cities both natural constraints and government regulations on urban land use can cause urban land shortages and hence higher prices of urban land and housing than otherwise there have been attempts to investigate the differential effects of natural and contrived restrictions on land price for w x example rose 10 found that natural constraints have a significant positive impact on land value while monopoly zoning power makes a smaller contribution in explaining inter city variations in urban land price w x on the other hand pollakowski and wachter 8 analyzed the impact of land use controls measured by an index of restrictiveness of zoning and confirmed that land use regulations raise the prices of housing and developed land to the best knowledge of the authors however none of the published empirical studies including the two cited above actually measure the amount of shortage of urban land at the city level instead land supply variables are employed together with demand variables such as income and population size to determine their impact on land or housing prices this study seeks to fill the gap in the literature first by developing a measure of the urban land shortagersurplus from an analysis of land price

the political economy of korean government policies on real estate this paper investigates the driving forces behind the korean government s real estate policy decision making in particular it tries to explain why inefficient and inequitable policies have persisted for so long and why policy reform has been so sluggish in order to do this a few key regulations governing housing supply and land use are described and evaluated these are the price control on new apartments control on land use conversion green belts and spatial deconcentration policies next it is demonstrated that the standard economic theory of interest group politics is not appropriate in explaining the behaviour of the government officials in charge of these regulations it is then suggested that a piecemeal and lukewarm approach to policy reform could be better understood in light of the behaviour of risk averse government officials taking the political ramifications of their decisions very seriously

energy taxation and the double dividend effect in taiwan s energy conservation policy an empirical study using a computable general equilibrium model abstract faced with pressure from greenhouse gas reductions and energy price hikes the taiwan government is in the process of developing an energy tax regime to reflect environmental external costs and effectively curb energy consumption as well as mitigate co2 emissions through an adequate pricing system this study utilizes a cge model to simulate and analyze the economic impacts of the draft energy tax bill and its complementary fiscal measures under the assumption of tax revenue neutrality the use of energy tax revenue generated for the purpose of reducing income tax is the best choice with double dividend effects since it will effectively stimulate domestic consumption and investment and consequently mitigate the negative impacts of the distortionary tax regime the double dividend effect is less significant however when the supplementary measures being used are for government expenditure nevertheless all supplementary measures have effectively reduced energy consumption which means they have delivered at least the first dividend in the sense of co2 emissions control it has been verified in this study that having adequate public finance policy measures is the key to realizing the double dividend effect

examining for evidence of the leapfrog effect in the context of strict agricultural zoning while strict agricultural zoning policies or greenbelts are implemented to reduce urban sprawl such policies may result in the leapfrog effect which could cause sprawl to extend further this paper outlines a theoretical explanation for the occurrence of the leapfrog effect due to developent restrictions imposed by agricultural zoning this theory is then applied empirically to a setting where agricultural zoning has been implemented ontario s greenbelt the results provide evidence that the leapfrog effect has occurred around the greenbelt as farmland values just beyond the outer boundary have increased extensive sensitivity analysis supports this result jel q15 r52

green throughput taxation environmental and economic consequences according to optimal taxation theory raw materials should be taxed to capture the embedded scarcity rent in their value to reduce both natural resource use and the corresponding emissions or the throughput in the economic system the best policy may be a tax on material inputs as a first approach to throughput taxation this paper considers a tax on intermediates in the framework of a dynamic computable general equilibrium model with environmental feedbacks to balance the budget payroll taxes are reduced as a result welfare indicators as material consumption and leisure time consumption are reduced while on the other hand all the environmental indicators improve

environmental levies and distortionary taxation pigou taxation and pollution i note an important distinction between the optimal price of environmental quality in a second best world and the optimal level of environmental quality using an analytical general equilibrium model i show that for reasonable parameter values an increase in tax distortions arising from an increase in required tax revenues leads to a fall in the optimal pigouvian tax rate even while environmental quality improves in general knowledge of the direction of changes in optimal environmental tax rates due to changes in the economy is not sufficient for understanding the impact on environmental quality 2003 elsevier science b v all rights reserved

optimal control of externalities in the presence of income taxation optimal control of externalities a substantial literature examines second best environmental policy focusing particularly on how the pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation additional literature is motivated by the possibility that distributive concerns should amend the internalization prescription it is demonstrated however that simple first best rules unmodified for labor supply distortion or distribution are correct in a natural basic formulation of the problem specifically setting all commodity taxes equal to marginal harms and subsidies equal to marginal benefits can generate a pareto improvement likewise a marginal reform in the direction of the first best can yield a pareto improvement for other reforms a simple efficiency test characterizing when a pareto improvement is possible is offered qualifications and explanations for the substantial departure from results in previous work are also elaborated

optimal dynamic carbon taxes in a climate economy model with distortionary fiscal policy how should carbon be taxed as a part of fiscal policy the literature on optimal carbon pricing often abstracts from other taxes however when governments raise revenues with distortionary taxes carbon levies have fiscal impacts while they raise revenues directly they may shrink the bases of other taxes e g by decreasing employment this article theoretically characterizes and then quantifies optimal carbon taxes in a dynamic general equilibrium climate economy model with distortionary fiscal policy first this article establishes a novel theoretical relationship between the optimal taxation of carbon and of capital income this link arises because carbon emissions destroy natural capital they accumulate in the atmosphere and decrease future output consequently this article shows how the standard logic against capital income taxes extends to distortions on environmental capital investments second this article characterizes optimal climate policy in sub optimal fiscal settings where income taxes are constrained to remain at their observed levels third this article presents a detailed calibration that builds on the seminal dice approach but adds features essential for a setting with distortionary taxes such as a differentiation between climate change production impacts e g on agriculture and direct utility impacts e g on biodiversity existence value the central quantitative finding is that optimal carbon tax schedules are 8 24 lower when there are distortionary taxes compared to the setting with lump sum taxes considered in the literature

energy taxes in the netherlands what are the dividends in this paper the environmental and economic effects of the introduction of a unilateral energy tax in the netherlands are analysed using an applied general equilibrium age model the effects of a small user energy tax and a general energy tax are compared while taking into account different tax recycling mechanisms the model contains a great level of detail with respect to emissions and environmental indicators greenhouse effect acidification eutrophication and waste which is helpful for assessing environmental quality the results show that the introduction of a small environmental tax reform not only improves the environment but also raises non environmental welfare which is due to an improvement of the efficiency of the tax structure

green policies and public finance in a small open economy we explore the effects of greener preferences for the public finances employment and the domestic capital stock in a second best framework we find that greener preferences typically result in capital flight also employment declines despite the factor substitution that is induced by a lower tax on labour and a higher tax on natural resources if the uncompensated wage elasticity of labour supply is positive private utility declines public consumption in contrast may rise if most of the improvement in environmental quality occurs through a lower level rather than a cleaner composition of economic activity however if the labour supply curve bends backwards private utility rises while public consumption falls i introduction the deterioration of the natural environment constitutes one of the major challenges facing public policy today business groups are concerned that environmental protection induces both capital flight and major losses in private income environmental groups in contrast maintain that a more ambitious environmental policy may not impose large costs in particular environmental taxation may be attractive especially for the high tax countries of western and northern europe in these countries the

environmental tax interactions when pollution affects health or productivity abstract recent studies indicate that interactions with the tax distorted labor market increase the cost of pollution regulation however these studies make restrictive assumptions regarding preferences and ignore key links between pollution human health and labor productivity together these assumptions imply that pollution does not affect labor supply this paper develops an analytical general equilibrium model that considers several potential benefits from reduced pollution including improved health or productivity it shows that these benefits affect labor supply and thus create a benefit side tax interaction effect that can be of the same magnitude as the familiar cost side interaction when reduced pollution boosts labor productivity the effect substantially magnifies such benefits in contrast when pollution affects consumer health the effect tends to diminish the benefits of reduced pollution the paper considers only environmental regulation but these concepts apply equally to other policies affecting productivity or health such as research subsidies or occupational safety regulations

on the double dividend under imperfect competition we investigate whether and under which conditions a revenue neutral environmental tax reform may yield an employment double dividend i e an improvement of environmental quality and an increase in aggregate employment using a model with two market imperfections a rigid real wage and imperfect competition in one industry we show that an employment dividend is plausibly obtained however for countries where labor taxes are high and households spend a large share of their income in favor of environmentally harmful consumption goods a double dividend can nevertheless not be obtained for under these conditions environmental quality deteriorates

alleviating unemployment the case for green tax reforms abstract it has been argued recently that imposing taxes on pollution produces additional tax revenues which can be used to replace labour taxes and thus reap a double dividend in the form of improving environmental quality and alleviating unemployment this paper analyses the employment effects of revenue neutral green tax reforms by focusing on the revenue recycling effect our model contains three features which are important when looking at the employment effects of green tax reforms first there is unemployment in equilibrium second wages are determined endogenously third various institutional arrangements for taxing unemployment benefits for the price indexation of unemployment benefits and the personal tax exemption are considered it is shown that these institutional arrangements are crucial for the effectiveness of green tax reforms a revenue neutral green tax reform will boost employment if unemployment benefits are nominally fixed and taxed at a lower rate than labour income employment actually falls if unemployment benefits are price indexed and taxed at the same rate a revenue neutral green tax reform which increases the personal tax credit will never increase employment

tax reform structural unemployment and the environment the effects of environmental tax reform i e using the proceeds of a higher energy tax rate to lower the labour tax rate on wage formation employment and environmental quality are analysed in the context of a small open economy with structural unemployment caused by hiring costs we find that such a reform may boost employment if it shifts the tax burden away from workers towards those without employment in the formal sector environmental tax reform succeeds in shifting the tax burden away from workers in the formal sector if higher energy taxes reduce earnings in the informal sector by reducing labour productivity

taxation unemployment and growth dynamic welfare effects of green policies abstract this paper analyzes the effects of environmental tax reforms on a small open economy the labor market is characterized by union wage setting the carbon tax acts as an implicit tariff which gives rise to terms of trade gains the terms of trade effect together with the union wage setting leads to a positive relationship between the capital labor ratio and net foreign wealth in the short run the disinvestments in real and financial capital give temporary room for higher consumption and instantaneous utility the long run effect on instantaneous utility is more uncertain a strong double dividend may exist

consequences of environmental tax reform for involuntary unemployment and welfare we investigate the welfare effects of environmental tax reform i e raising environmental taxes and using the proceeds to reduce distortionary taxes on labour the framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage environmental tax reform boosts not only environmental quality but also employment if substitution between labour and resources is easy the production share of the fixed factor is large and the initial tax rates on resources and profits are small if the initial tax system is sub optimal with a negligible tax on resources profits rise as well
