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.     

Social Structure in Economic Theory

This paper investigates the factors that drive ruler decision making under democracy. By dividing politicians’ actions into two distinct domains and exploring their compositions, we construct a fuller and more realistic picture of politician decision making. In the non-discretionary domain, the politician’s actions are clearly limited by voter desires; in the discretionary domain the politician is free to make choices as he chooses without voter repercussions. Standard neoclassical models of political behavior suggest that when votes don’t matter, monetary income drives ruler behavior. While monetary pursuit may explain some ruler decisions, it leaves many other observed choices unexplained. Our non-discretionary/discretionary dichotomy highlights the up-to-now neglected role that psychic income plays in explaining otherwise unexplained ruler decisions. The case studies considered support this view.     

中国城乡有效经济增长的差异性分析

本文提出了有效经济增长的概念,构建了有效经济增长动态模型,利用该模型建立了超额人均收入等相关变量的测定方法。在此基础上分别测算我国城镇部门与农村部门有效经济增长的相关指标,并进行比较分析。结果发现,改革开放以来我国城镇部门有效经济增长无论从绝对量上还是增长速度上都明显高于、快于农村部门;城镇部门有效经济增长的减损量大于农村部门;而农村部门对有效经济增长的减损强度却大于城镇部门。因此,推动城市化且合理控制城市化进程的速度,是降低我国有效经济增长的减损强度,实现有效经济增长可持续性的有力途径。     

试论调控个人收入分配的财税政策选择

根据实际情况，我国政府调控个人收入分配，在财政政策方面，应加快完善社会保障制度，加大转移支付力度，缩小地区经济差距，加大扶贫投入的力度；在税收政策方面，应进一步完善个人所得税制度，适时开征遗产税与赠与税，加强特别消费税的作用，建立个人财产税制，适时开征社会保障税。     

全面收益理论与损益确认原则--实现原则、权责发生制原则利弊谈

收益指标是财务报表使用者特别是投资人最为关心的会计信息.美国会计学者利特尔顿认为,收益是企业会计的重心,收益表是企业会计最重要的产品.历史成本原则、实现原则、配比原则是传统收益确定模式的重要支柱.全面收益突破了实现原则,更好地体现了权责发生制原则的要求,并在会计确认中坚持了适当稳健的原则,有利于提供与信息使用者决策相关的可靠信息.
