消费税制的国际比较及其对我国的启示

消费税制改革是我国新一轮税制改革的任务之一。改革和完善我国消费税制，应借鉴国外一些成功经验，丰富和完善我国消费税的立法原则，适当扩大征税范围，调整税收负担，改革计税依据和征税方法。     

Do we now collect any revenue from taxing capital income?

The U.S. income tax system has long been recognized as a hybrid of an income and consumption tax system, with elements that do not fit naturally into either pure system. What it actually is has important policy implications for, among other things, understanding the impact of moving closer to a pure consumption tax regime. In this paper, we examine the nature of the U.S. income tax system by calculating the revenue and distributional implications of switching from the current system to one form of consumption tax, a modified cash flow tax.     

Energy taxation in Southern Europe: The case of Portugal

We investigate whether or not the imposition of a common EC energy-tax will penalize more the poorer Southern European economies and if this will harm convergence at the EC level. We start by surveying briefly the existing studies and empirical evidence. Then we exploit the results obtained when using the macroeconometric HERMES models to simulate the introduction of an energy-tax. Unfortunately, as we only have HERMES results for one Southern European economy, Portugal, our conclusions are limited. Finally, we investigate convergence in Europe and the effects of energy taxation on convergence. We conclude that energy taxation will harm growth all over the EC, penalizing more one of the less developed countries, Portugal, and having most probably adverse effects on convergence.This paper was prepared for presentation at the Conference Energy Tax in Europe organized jointly by the SEO-University of Amsterdam and the DG XII of the CEC and held in Amsterdam on 13th December 1991. I would like to thank the participants in the Conference and two anonymous referees for helpful comments. Of course, the usual disclaimer applies.     

Endogenous human capital accumulation, comparative advantage and direct vs. indirect redistribution

Recently, several papers have reexamined the so-called production efficiency theorem and the Atkinson and Stiglitz theorem on commodity taxes in the optimal taxation literature. Naito [J. Public Econ. 71 (1999) 65] showed that indirect redistribution through production distortion or consumption distortion can Pareto-improve welfare and that the two theorems do not necessarily hold when different factors are imperfect substitutes and factor prices are endogenous. On the other hand, Saez J. Public Econ. (2002) forthcoming argued that in the long run, where human capital accumulation is endogenous, the two theorems are still valid. This paper develops reasonable alternative models where individuals accumulate human capital based on their comparative advantage. The present paper shows that the production efficiency theorem is not necessarily valid and that indirect redistribution from the able to the less able such as tariffs and production subsidies can increase efficiency even when skill accumulation is endogenous.     

The optimal treatment of tax expenditures

This paper analyzes the optimal treatment of tax expenditures. It develops an optimal tax model where individuals derive utility from spending on a “contribution” good such as charitable giving. The contribution good has also a public good effect on all individuals in the economy. The government imposes linear taxes on earnings and on the contribution good so as to maximize welfare. The government may also finance directly the contribution good out of tax revenue. Optimal tax and subsidy rates on earnings and the contribution good are expressed in terms of empirically estimable parameters and the redistributive tastes of the government. The optimal subsidy on the contribution good is increasing in the size of the price elasticity of contributions, the size of the crowding out effect of public contributions on private contributions, and the size of the public good effect of the contribution good. Numerical simulations show that the optimal subsidy on contributions is fairly sensitive to the size of these parameters but that, in most cases, it should be lower than the earnings tax rate.     

在科学发展观下建立绿色税收体系

随着经济的发展，社会环境与经济发展矛盾日益尖锐，在科学发展观下建立绿色税收体系的提出正是为了顺应社会发展趋势，为缓解和解决这一矛盾提供有效的途径。     

农村税费改革中存在的问题及对策

农村税费改革后,农民的负担减轻了,但税费改革中新出现的一些问题严重影响了税费改革的进程和效果。我国农村税费改革存在着城乡之间、城区与非城区农民之间负担不均衡、农村义务教育投入严重不足、村级经费短缺等亟待解决的问题。为此,应采取加大农村政府机构改革的步伐和力度、加大对农村义务教育的投入、加大中央和省级两级财政转移支付力度等措施,进一步完善农村税费改革。     

Growth,Employment and Taxation with Distortions in the Goods and Labour Market

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms.     

融资制度变革的内在逻辑和次序安排

本文主要目的在于探讨我国当前金融制度的问题,并尝试探讨融资制度变迁的内在逻辑和次序安排,希望以此作为政策制定之参考。本文认为,国有经济改革、非公有经济发展以及农村经济发展等使国家改革现行融资制度的动力很足,但与此对应,各有关主体对改革现行融资制度的动力明显不足,提高融资制度效率的关键在于所有制和竞争力上。文章还在国有商业银行股份制改造、农村金融制度、非正规金融、监管和利率等方面提出了相应的建议。
