This paper examines the welfare impact of emission taxes and subsidies in a green market where consumers emit a pollutant through their usage of products produced by duopolists. For this purpose, we employ a discrete?Ccontinuous model including both consumer choice and usage of an environmentally differentiated product in a utility-consistent framework. The findings indicate that an emission tax is always welfare dominant over a subsidy on consumer purchases of the clean product because of its contribution to a reduction in environmental damage. It does this by both inducing firms to improve the environmental qualities of their products and by constraining consumer usage of these products.  相似文献

The paper considers trade between identical countries with imperfectly competitive markets, and compares the impacts of regional and multilateral tariff reduction on strategic environmental taxation and welfare. While both forms of trade liberalization increase production and consumption in tariff‐reducing countries, regionalism also reduces production in a non‐participating country and may decrease its consumption. Consequently, regionalism and multilateralism change pollution tax and welfare in the tariff‐reducing countries in similar ways when pollution is local, but in dissimilar ways for global pollution. When pollution is global, regionalism is likely to be preferred to multilateralism for the establishment of free trade among countries.  相似文献

This paper addresses optimal taxation, when therelationship between the consumption of a`dirty' good and the resulting environmentaldamage is uncertain and treated as a randomvariable by policy makers. The main purpose isto analyze how increased uncertainty, measuredas a mean preserving increase in the spread ofthis random variable, affects the optimalcommodity tax on the dirty consumption good. Incase the only task of government is to correctthe environmental externality, and if thepreferences are characterized by nondecreasingabsolute risk aversion, we find that thecommodity tax on the dirty consumption goodincreases in response to additionaluncertainty. If, on the other hand, thegovernment provides a public good and uses alump-sum tax in addition to the commodity tax,it is possible that the commodity tax decreasesas a response to additional uncertainty, evenif the preferences are characterized bynondecreasing absolute risk aversion. A similarresult emerges, although for different reasons,if the lump-sum tax is replaced by a laborincome tax.  相似文献

This paper examines the potential role for fuel substitution in electricity production in reducing carbon dioxide emissions over a ten-year time horizon. This is achieved by adding fuel substitution to output changes resulting from demand responses arising from a tax on carbon dioxide emissions. A time profile of adjustments is developed. The tax required for Australia to meet a 20 per cent reduction in emissions from 1993 levels is calculated and effects on inequality and social welfare are examined. The paper also examines the potential effect of a subsidy towards the use of low-emission fuels, financed from the carbon tax. A subsidy produces an improvement in emissions abatement and a lower tax required to reach the emissions target.  相似文献

This paper computes the change in welfare associated with the introduction of incentives. We calculate by how much the welfare gains of increased output due to incentives outweigh workers' disutility from increased effort. We accomplish this by studying the use of incentives by a firm in the check-clearing industry. Using this firm's production records, we model and estimate the worker's dynamic effort decision problem. We find that the firm's incentive scheme has a large effect on productivity, raising it by 12% over the sample period for the average worker. Using our parameter estimates, we show that the cost of increased effort due to incentives is equal to the dollar value of a 5% rise in productivity. Welfare is measured as the output produced minus the cost of effort; hence, the net increase in the average worker's welfare due to the introduction of the firm's bonus plan is 7%. Under a first-best scheme, we find that the net increase in welfare is 9%.  相似文献

This paper examines methods used to evaluate the welfare effects of tax changes, with emphasis on the measurement problems involved. Welfare changes and excess burdens are defined, along with approximations. Aggregate measures, using a social welfare function, are examined. The special case of income taxation is then examined, leading to discussion of the marginal welfare cost of taxation and the marginal cost of funds. The measurement methods examined include the use and estimation of direct and indirect utility functions, along with the algebraic and numerical integration from estimated Marshallian demand functions to the compensated demands. The use of equivalent incomes to examine tax changes, using unit record data from household budget surveys, is then discussed.  相似文献

环境成本的内部化与环境税制变迁   总被引:2,自引:0,他引:2  
本文分析了环境成本产生的经济学根源,进而分析了环境成本内部化的途径.研究发现,政府环境税收政策的实施对企业利润的影响决定了环境成本内部化的途径.在完善的环境税制下,征收环境税可以促使污染企业外部成本内部化,因而环境税制是一种有效的环境经济政策.中国还没有开征专门的环境税,目前的税制在保护环境上发挥的作用不明显,有必要开征专门的环境税.本文运用制度变迁理论探讨了中国环境税制变迁的路径.  相似文献

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.  相似文献

运用短期局部均衡分析方法研究完全竞争市场和垄断市场条件下环境税对社会福利的影响.结果显示:在完全竞争市场条件下,对企业征收环境税可以增进社会福利.而在垄断市场条件下,环境税的福利效应具有不确定性,这取决于垄断造成的扭曲程度.如果垄断造成的扭曲较小,环境税仍然可以提高社会福利.但无论是增进抑或降低社会福利,对垄断企业征收环境税都不可能实现最优化,因为环境税在矫正污染外部性的同时,垄断造成产量水平下降导致福利损失增加,所以只能追求一个次优的结果,次优环境税低于完全竞争条件下的标准环境税.  相似文献

This paper considers a trade situation where the production activities of potentially heterogeneous countries generate pollution which can cross borders and harm the well-being of all the countries involved. In each of those countries the policy maker levies pollution taxes on the polluting firms and a tariff on imports in order to correct that distortion. The purpose of the paper is to investigate the effect of a reduction in the tariff on equilibrium pollution taxes and welfare. The existing literature has investigated this problem for trade between two identical countries. This paper analyzes the problem in the more realistic context where countries are not necessarily identical and trade can be multilateral. It becomes possible to show what bias is introduced when those two realities are neglected. I find that a tariff reduction can actually lower output; it can also lower welfare even if pollution is purely local.  相似文献

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.  相似文献

Environmental Taxation and Strategic Commitment in Duopoly Models   总被引:2,自引:1,他引:2  
In this paper, we address the issue of optimalenvironmental taxation under imperfect competition.The problem is analysed for three different types ofduopoly models, the Cournot open and closed loopmodels, and the Stackelberg model. We explicitlyanalyse the role of strategic behaviour. Each firm hasto make a choice of output level and of the level ofa strategic variable. The choice of this strategicvariable affects both marginal cost and emissions. Wecompare the properties of these three duopoly models,and derive and compare optimal environmental taxes. Weshow that whether the optimal tax is lower or higherthan marginal environmental costs depends on theinformation transmission and the effect of thestrategic variable on marginal costs. In addition, thedifferences in market shares, and the influence of thetax on the cost structure play important roles, indetermining optimal emission taxes.  相似文献

This paper addresses some features of environmental funds that the government uses to finance public abatement with pollution tax revenue or tariff revenue. I find that when the pollution tax rate and the tariff rate are jointly chosen optimally, then the optimal pollution tax rate is higher than the Pigouvian tax rate under public abatement financed by tariff revenue, and lower when public abatement is financed by pollution tax revenue. Furthermore, I show that the optimal tariff rate is positive regardless of which tax revenue is used to finance public abatement. These results are relevant for countries where the government seeks revenues earmarked for the financing of environmental funds.  相似文献

Permitting allowance banking in emissions trading programs can reduce expected compliance costs by giving capped firms flexibility to adjust the time path of abatement and to hedge against future uncertainty. Recent literature suggests that this compliance cost dividend is significant (Fell and Morgenstern Environ Resour Econ 47:275–297, 2010). Allowance banking may yield an environmental dividend (a) if the growth rate of marginal damages from emissions is less than the discount rate and (b) if emissions are lower in the short run as firms bank permits for use in later periods. A discrete, stochastic dynamic programming model is considered to simulate the two dividends of allowance banking in the context of the most recent Federal United States greenhouse gas cap-and-trade legislation. Simulation results show that under a range of parameter values, the environmental dividend has the same order of magnitude as the compliance cost dividend. Under the central set of parameters, allowance banking increases expected present value of benefits by about $350$ million dollars per year of the program. The environmental dividend, however, is completely eliminated if capped firms can borrow permits from future periods without limit.  相似文献

Consequences of Environmental Tax Reform for Unemployment and Welfare   总被引:4,自引:0,他引:4  
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.  相似文献
