论个人所得税存在的问题及改革方向

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。     

Double Dividend with Involuntary Unemployment: Efficiency and Intergenerational Equity

This paper analyzes the double dividend and distributional issues within an overlapping generations model framework with involuntary unemployment. We characterize the necessary conditions needed to obtain a double dividend, when the revenue of the environmental tax is recycled by a variation of the labor tax rate. We show that an employment dividend may occur without any efficiency dividend and that the young generation is not always harmed by the fiscal reform, even without any intergenerational transfers. Therefore, three dividends (environmental, efficiency and intergenerational equity) can occur simultaneously.     

Environmental tax policy in a model of growth cycles

Summary. The purpose of this paper is to consider environmental taxation which would control emissions of firms in a model of growth cycles. In the model presented below, the economy may experience two phases of growth and environmental quality: “the no-innovation growth regime” and “the innovation-led growth regime”. Aggregate capital and environmental quality remain constant in the no-innovation growth regime, while they perpetually increase in the innovation-led growth regime. The paper shows that the tax plays a key role in determining whether the economy stably converges to one of the two regimes or fluctuates permanently between them. It also shows that there is a critical level of the tax and that the economy obtains higher growth rates of capital and environmental quality by raising (or reducing) the tax if the initial tax is below (or above) the critical level.

Rethinking the costs related to global warming: A survey of the issues

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.     

How efficient are national environmental standards? A benefit-cost analysis of the United States experience

This paper summarizes the results of the first systematic, geographically-specific efficiency assessment of the U.S. experience with national environmental standards and with alternative approaches to establishing those standards. This ex-post evaluation assessed the net benefits that resulted from EPA's regulation of conventional air and water pollutants from the pulp and paper industry between 1973 and 1984. The paper compares the benefit-cost efficiencies of the three dominant regulatory approaches: technology, ambient, and benefits. Unlike previous studies, which assessed benefits and costs on a national basis, the study estimates both costs and benefits on a facility-by-facility basis. The analysis shows how the efficiency of national environmental regulations can vary dramatically at local levels. The authors conclude that the technology-based standards for water pollution management failed as an efficient environmental strategy. The costs clearly exceeded the benefits in the aggregate, as well as in the specific in most situations. Benefits exceeded costs at only 11 of the 68 mills investigated. The ambient based standards for air pollution management succeeded as an environmental strategy in the aggregate, but succeeded in the specific for only one-third of the mills (22 of 60 mills). The benefits-based standards for air pollution management also succeeded in the aggregate as well as in the specific for about one-half of the mills. Benefits exceeded costs at 29 of the 60 mills investigated. The results of the study point to two major conclusions. First, a regulatory policy that is based on some measure of environmental results, either ambient-based or benefits-based, will be more efficient than a policy that ignores environmental results. Second, truly efficient policies for reducing environmental risks require pollution mitigation decisions that take into account local conditions. These include not only the changes in local ambient conditions, but also the number of people who will benefit from pollution reduction decisions. This latter conclusion suggests that national environmental standards per se may be inefficient.Dr. Luken is currently Senior Environmental Advisor to the United Nations Industrial Development Organization (UNIDO) in Vienna, Austria.

Domestic and international strategic interactions in environment policy formation

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.

浅析我国企业所得税改革——写在2007年“税合一”出台之际

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。     

OECD税制绿色化与我国之借鉴

OECD成员国在实现税制绿色化方面采取的值得我国借鉴的措施有:取消或修正现行扭曲性的补贴和税收条款,调整现行税制,开征新的环境税.基于对我国现实国情的考虑,将实现税制绿色化的重点放在开征新的环境税-环境污染税和某些资源税上,并以改革现行税制与逐步消除对环境不利的补贴政策辅助之.
