Several countries have introduced taxes on fossil fuels with the aim of reducing atmospheric emissions, partly because of
local environmental goals (SO2, NOx) and partly to participate in a global effort to reduce emissions of greenhouse gases. Many macroeconomic studies, based
on both global and national models, have been made of how emissions can be reduced with the help of taxes and the consequent
reduction in GDP following the introduction of such taxes. Norway has had a CO2 tax for five years, thereby providing a unique opportunity to evaluate the effects of this tax on emissions. The paper provides
a counterfactual analysis of energy consumption and emissions if no CO2 taxes had been introduced, compared with the actual situation in which such taxes exist. The effect of a CO2 tax on oil consumption, and thus CO2 emissions is studied on the basis of partial economic models for various sectors of the Norwegian economy. The study indicates
that the CO2 tax has had an impact on CO2 emissions in Norway. 相似文献

Taxation of Mobile Factors as Insurance under Uncertainty 总被引:1,自引:0,他引:1
Kangoh Lee 《The Scandinavian journal of economics》2004,106(2):253-271
This paper considers the effects of the taxation of mobile factors, i.e., capital, under uncertainty. The wages earned by residents of a jurisdiction are uncertain due to random shocks. Since the uncertain wages in a jurisdiction depend on the amount of mobile capital employed in the jurisdiction, and since taxation alters the quantity of capital employed, taxation affects the riskiness of uncertain wages. In particular, the taxation of capital moderates the fluctuation of uncertain wages, thereby providing insurance. For this reason, jurisdictions use distortionary capital taxation even if lump‐sum taxation is available. In addition, this insurance effect counteracts the tendency toward too low tax rates on capital arising from tax competition, and possibly improves the efficiency of tax competition. 相似文献

Emission of CO2, SO2 and NOx are all closely linked to the burning of fossil fuels. Here we report on simulations done by linking a Sectoral European Energy Model (SEEM), covering energy demand in nine Western European countries, with the emission-transport-deposition model RAINS developed by IIASA. The study analyses emissions of CO2, SO2 and NOx, deposition of sulphur and nitrogen and the extent of areas where the critical load for sulphur is exceeded in year 2000 under four different energy scenarios. Two different sets of future behavioural patterns for the thermal electric power production sector are considered. In one regime, called the plan-efficient regime, the sector is assumed to follow official plans with regard to investment in new capacity. In the other regime, called the cost-efficient regime, the thermal power sector is assumed to behave in a cost minimizing manner. The effects of the proposed EC carbon/energy tax are studied under both regimes, giving rise to altogether four scenarios.In both regimes the effect of the EC tax is to reduce emissions by between 6 and 10 per cent in year 2000 relative to the scenarios without the tax. A change of regime, from the regulated, plan-efficient regime to the market-based, cost-efficient regime, will, by itself, reduce emissions of CO2 and NOx by approximately 3 per cent, while SO2 emissions are reduced by 13 per cent. The EC tax will reduce sulphur deposition by more than 5 per cent in the nine model countries under the plan-efficient regime. A change of regime further reduces the total deposition by 9 per cent. The area where depositions exceed the critical load is reduced by approximately 6 per cent in year 2000 by the tax in both regimes. Changing from the plan-efficient to the cost-efficient regime has a similar impact.Although the emission reductions due to the EC tax may seem modest, they are shown to have a sizeable effect on the technological abatement costs of reaching targets like those prescribed in the Sofia protocol on the stabilisation of NOx emissions, and the Helsinki protocol on SO2 emission reductions. This is part of what can be considered to be secondary benefits of the EC carbon/energy tax. 相似文献

Pollution externalities between polluters should be taken into account in the design of corrective taxes. When the externalities are substantial and/or the number of polluters is large, the effluent levies on these firms do not necessarily result in a deadweight loss. Consequently, the second-best tax exceeds the marginal social cost of pollution. A more general rule is that the tax rate should be greater than the marginal social cost of pollution if and only if a marginal increase in the tax rate results in opposite effects on the changes of equilibrium emission level and output. 相似文献

One approach to the economic analysis of global warming seeks to balance the costs of damage from or adaptation to it with the costs of mitigating it. The costs of adaptation and damage have been estimated using techniques of environmental evaluation, but are subject to a wide margin of uncertainty. The costs of mitigation, principally by reducing the emissions of CO2, have been estimated using different kinds of economic models, some of the results of which have suggested that very little abatement of carbon emissions is justified before the costs of abatement exceed the benefits of it in terms of foregone damage and adaptation costs. The paper analyses the extent to which this conclusion is a function of the modelling assumptions and techniques used, rather than likely practical outcomes, with regard to the models' treatment of unemployed resources, revenue recycling, prior distortions in the economy due to the tax system and possible dynamic effects from the introduction of a carbon-energy tax. It concludes that, with different and arguably more appropriate treatment of the above issues, especially when the secondary benefits of reducing CO2 emissions are also taken into account, it is not clear that even substantial reductions in the use of fossil fuels will incur net costs, especially if there is the prospect of even moderate costs from global warming. 相似文献

Summary. In this paper, we establish the most possilbe general formulation of the technology governing carbon-gas emission, giving
rise to global external diseconomies, and ty to explore into the strategic interactions,both domestic and international, when
an individual country decides on the environmental policies. Through the comparison among emission taxes, quotas, and standard
in the perfectly competitive private economies, we find that the first two policies are equivalent but they are different
in effects by virtue of what we may call the tax-exemption effect of emission standards. Such a difference in the policy effect
further affects the other country's welfare through the global externalities, amplified through whether the government can
precommit to either the emission tax or the emission standard.

2007年3月14日,提交全国人大审议的企业所得税法草案规定,将内外资企业所得税税率统一为25%,法定税率由33%降低了8个百分点。外资实际税率要从15%变成25%,内资要从33%下降到25%。大多数的声音是,这项政策对外资企业是一种公平合理的国民待遇,对内资企业则是一种重要的激励。这将会使市场竞争朝着更加公平的方向发展。本文通过对这项具有里程碑意义的税改政策出台的背景、影响等方面加以综合分析,并归纳整理了该政策出台后理论界、业界的不同观点,为新税制的发展提供了展望。 相似文献

金融工具会计准则交易税制设计的思考 总被引:1,自引:0,他引:1
为了规范金融工具的确认和计量,反映金融工具对金融机构财务状况和经营成果所带来的真实影响,揭示其潜在风险,提高金融机构的会计信息的质量,新颁布的金融工具会计准则采用公允价值计量,并将损益纳入当期损益。本文分析了此举对我国税制所产生的影响,并对金融工具交易的税制设计提出了设想。 相似文献
