税务征收体制下的社会保险费征管制度建设研究

我国社会保险费征管体制改革正在不断深入。当前,社会保险费征管仍存在制度设计有待完善、法律依据不够清晰的问题。本文基于税收征管视角,对社会保险费征管制度进行了重新审视,在全面梳理了制约社会保险费征管制度完善的限制性因素的基础上,从科学设置社会保险费征管前置程序、全面构建社会保险费征管的保障程序等多个方面,对将社会保险费征管融入税收征管流程的可行性进行了分析和探讨,以期为我国社会保险费征管制度的完善提供参考。     

Progression and revenue effects of income tax reform

Usually, only initial revenue effects of personal income tax reforms are considered. However, a tax reform characterized by base broadening in exchange for rate reduction can reduce the income elasticity of tax revenue. In that case, the increase in revenue after income growth will be relatively smaller: the tax reform has a negative effect on revenue in the second period. Using the microtax model of the Central Planning Bureau we simulated the effects of the Dutch Oort reform 1990 on revenue elasticities and, consequently, on tax revenue. The income tax revenue elasticity declined by 17 percent which caused an additional revenue loss of 0.6 percent in 1990, rising to 3.8 percent in 1993.     

Why Capital Income Taxes Survive in Open Economies: The Role of Multinational Firms

This paper discusses the role of multinational firms and double taxation treaties for corporate income taxation in open economies. We show that it is optimal for a small open economy to levy positive corporate income taxes if multinational firms are taxed according to the full taxation after deduction system or the foreign tax credit system. Positive corporate taxes also occur in the asymmetric case where some countries apply the exemption system and others apply the tax credit system. If all countries apply the exemption system, the optimal corporate income tax is zero. We also show that, under tax competition, corporate income taxes are not necessarily too low from the perspective of the economy as a whole. While the undertaxation result is confirmed for the case of the exemption system, tax rates may also be inefficiently high if the deduction or the credit systems are applied.     

关于不确定情况下净现值投资评价指标的探讨

文章对在不确定性情况下净现值（NPV）投资评价指标的有效性进行了探讨，提出在运用该指标评价项目时必须要考虑到风险的大小对项目决策的影响，并根据投资项目的统计特征。阐述了在此情况下该指标的计算。最后以实例进一步说明该计算方法的有效性。从而使项目的投资决策更为科学合理。     

Capital, corporate income taxes, and catastrophe insurance

We provide estimates of the equity capital needed and the resulting tax costs incurred when supplying catastrophe insurance/reinsurance using a partial equilibrium model that incorporates a specific loss distribution for US catastrophe losses. After consideration of insurer investment in tax-exempt securities, tax loss carry-back/forward provisions, and personal taxes, our results imply that the tax costs of equity finance alone have a substantial effect on the cost of supplying catastrophe reinsurance. These results help explain a variety of industry developments that reduce tax costs. Also, when coupled with non-tax costs of capital, these results help explain the limited scope of catastrophe insurance/reinsurance.     

基于政策目标的存款利息得税的有效性分析

我国1999年开征的存款利息所得税是一次典型意义上的相机调控行为,短期内达到了预期的调控目标。但随着政策持续时间的延长,政策刚性对社会公平和经济长期增长的负面影响也在逐步增强。而且相机性财政政策仅仅是一项短期政策,不应该被长期实施。相机性政策的长期实施不仅会使短期的政策效应丧失,而且政策刚性产生的负面影响将会不断扩大。对利息所得税而言,如果不能将其纳入个人所得税改革的整体框架内统筹安排,则应考虑尽快退出。     

存款保险法律制度利弊之研究

存款保险法律制度是直接针对银行挤兑和破产倒闭而设计的,目的在于保护存款人的利益,增强公众对银行体系的信心,减少挤兑的可能性。我国建立该制度,将有利于维护金融安全,营造公平竞争的市场环境,完善银行的退出机制,从而提高金融业的效率。     

改进我国个人工资薪金所得税的思考

个人工资薪金所得税是我国个人所得税的主体。我国现行个人工资薪金所得税的税制设计,在一定程度上制约着其功能的发挥。建议在完善我国个人工资薪金所得税功能定位的基础上,结合我国城乡居民的实际收入状况,对个人工资薪金所得税做进一步改进。
