云南少数民族地区可持续发展理念的形成和发展

在自然经济模式下,人们对资源的开发和利用十分有限,经济发展水平低,交流范围狭窄,因此,可持续性和生态平衡得以较好地维系。改革开放以来,特别是国家确立了建立社会主义市场经济体制的目标模式之后,少数民族地区的商品经济均有不同程度的发展,在国家确立了西部大开发和全面建设小康社会的战略目标之后,少数民族地区商品经济迅速发展起来。商品经济的发展对生态平衡和可持续性带来了前所来有的冲击,如何通过制度安排和技术手段来发展经济的同时保持生态平衡,实现可持续发展是少数民族地区经济发展面临的一个两难选择,为解决发展和保护之间的矛盾,云南少数民族地区可持续发展的理念便逐渐形成和发展起来。     

新一轮税改致力于完成的六大任务

启动新一轮税制改革,首先必须明确它所要完成的任务。这些任务包括:恰当界定宏观税负水平;政府收入行为及其机制的规范化;融入经济全球化;与财政安排体系相协调;税收中性与税收调控相结合;提升国家竞争力。     

论我国税收信息化的建设及其意义

我国税收信息化的建设与发展,特别是金税工程的建设、税收征管软件的推广应用和出口退税管理系统的信息化建设,极大地促进了我国税收管理的现代化进程。     

关于依法治税若干问题的思考

税收是市场经济条件下国家参与社会产品分配,进行宏观调控的重要手段。因此,市场经济要求强化税收,依法治国要求依法治税。税收征收管理的过程也就是贯彻执行税法的过程,依法治税是税收工作的立足点和灵魂所在,是依法治国的重要内容,也是当代中国政府和税务工作者为之探索和实践的重大课题。离开了依法治税,不仅税收工作本身得不到保障,市场经济也不可能正常发展。     

中国企业征税制度的一种新设计:TFO税

基于信息经济学的信号显示理论，提出了基于企业主业的行业平均利润率、公司经营时间和员工数量等三大关键变量，从企业外部来确定企业纳税额的中国式企业征税新制度（即TFO税），对现行征税制度进行了有效的改进，效率更高、成本更低。     

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.     

Noisy chaotic dynamics in commodity markets

The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003     

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.
