在公共品供给中,政府责任是提供它需要并且能够提供的公共品。需要提供的公共品是指在现有的资源技术条件下,达到社会效用最大化所需提供的公共品。能够提供的公共品是指征到拉弗曲线隐含的最大税收量所能提供的公共品。需要并且能够提供的公共品是指需要提供的公共品与能够提供的公共品中量较小的一方。通过比较政府实际提供的公共品与需要并且能够提供的公共品,可以评价政府在这一领域称职与否。 相似文献

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

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying. 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

我国自1980年开征个人所得税以来,特别是1994年新的“个人所得税法”颁布实施以来,个人所得税呈大幅度增长趋势,在税收中所占的比重也逐年提高,现今已经成为我国的第四大税种。但是随着我国市场经济体制的深入发展,居民收入水平的明显提高,个人所得税税制本身和征管中都存在和暴露了一些问题,对其进行改革已经势在必行。文中对我国现行个人所得税税制本身和征管中存在的一些问题进行探讨,并提出相应的改革思路。 相似文献
