我国可再生能源发展的经济学分析——基于租金理论视角

在常规能源资源逐步耗竭,生态环境日益恶化的背景下,可再生能源逐步替代常规能源成为大势所趋.但是目前我国可再生能源不仅没有与经济同步发展,甚至出现了常规能源对可再生能源的反替代.试图通过租金理论,分析我国可再生能源发展滞后的经济学原因,从而为我国加快发展可再生能源提出一些有针对性的政策建议.     

基于资源—能力—活动模型的商业模式创租机制研究

企业的不同租金类型来源于不同的商业模式活动。与商业模式资源—能力—活动模型相对应,存在资源选取和能力构建两种主要创租机制。这两种创租机制存在的独立性思维缺陷源自传统企业战略和企业理论中的＂资源—能力＂二分法。由于知识同时具有资源和能力属性,而知识来源于学习,因此,完善这两种创租机制、提高企业资源生产力和创租能力的思路是资源整合、知识积累和组织学习。     

农业与非农业地租的动态均衡分析

地租是马克思主义经济学中最富争议的问题之一。马克思的地租模型是特定历史条件下的产物,相对较低的农业资本有机构成和地权流转等因素一旦发生变化,马克思地租模型的结论便需要重新审视,而且马克思地租模型缺乏对非农用地地租问题的系统分析,可以说马克思的地租模型是一个局部的、静态的均衡分析。本文在坚持劳动价值论和生产价格理论的基础上,运用动态的一般均衡分析工具,把剩余价值、资本有机构成、地权流转等变量内生化,试图建立起关于农业和非农业绝对地租与级差地租的一般分析框架。     

马克思与李嘉图的地租理论比较研究

马克思的地租理论是在批判、继承、发展李嘉图地租理论基础上形成的，两者在地租理论方面有相同之处更有不同之处。李嘉图地租理论是建立在劳动价值论的基础上的，马克思对其给予了高度的评价，但也批判了李嘉图地租理论中的许多错误之处，并阐述了李嘉图错误的原因，在批判的同时继承、发展了他的地租理论，使地租理论成为一个科学和完善的理论。     

International Rent Sharing and Domestic Labour Markets: A Macroeconomic Analysis

Compared to international trade relations relatively little is known about the role foreign direct investment linkages play in the transmission of disturbances from one country to the next. Inspired by the microevidence on profit sharing within multinational corporations and within industries, we investigate for six countries whether a cross-border rent-sharing phenomenon can be identified at the macroeconomic level. The rent-sharing hypothesis implies that an increase in foreign profitability should boost wages and/or employment in the domestic economy. We find corroborative evidence for Belgium, France, Germany, the Netherlands and the United Kingdom. US labour market conditions, by contrast, are not affected by changes in profitability in other countries. JEL no. E32, F23, F40, J23, J31     

Group competition for rents

This paper examines rent dissipation in a two-stage group rent-seeking contest without a predetermined distribution rule. the rent in this setting exhibits both public and private good characteristics depending on the stage of the contest. Focusing on the relationship between group size and aggregate rent seeking we find that social waste depends not only on total numbers but also on the distribution of population across groups. We show that group size asymmetry acts to reduce rent dissipation.     

The Value of the Rent Control Option

In this paper, we combine direct arbitrage arguments and an option-pricing approach to develop a method of pricing the option for rent control. For a lump-sum payment of key money, a tenant acquires the right to rent a real estate unit for an exogenously determined controlled rent, as opposed to paying the free-market rent. The tenant may continue exercising this right as long as he or she lives. Alternatively, the tenant may sell the right to occupy the controlled rent unit and receive a fraction of the key money paid by the subsequent tenant. We value the equilibrium key money, in a representative agents partial equilibrium, while endogenously determining the expected tenure duration in a controlled rent unit. We propose a procedure for valuing rent control options different from the representative agents. Our analysis shows that under real-world levels of conditional life expectancy, the level of the fraction of the key money retained by a departing tenant has an insignificant effect on the expected tenure duration in a controlled rent unit and on the level of key money.     

现行企业所得税优惠政策评析

现行企业所得税制度已经运行十年有余,作为非基准税收制度的所得税优惠政策也越来越多,并且其执行效果不尽如人意。通过对现行所得税优惠的政策制度基础进行分析,可得出如下基本判断:两税并存是我国高税率、多优惠的制度基础;作为非基准税收制度的所得税优惠政策对基准所得税制度修订过多,税制的改革已成为必要;改革的方向是两税并轨,清理优惠,对于需要保留的税收优惠政策应贯彻以行业优惠为主、区域优惠为辅的原则。     

Energy Prices and Carbon Taxes under Uncertainty about Global Warming

This paper extends the strategic interactions between producers of fossil fuels concerned about their profits and a taxing government concerned about the consumers’ welfare for uncertainty: global warming follows an Itô -process. Stochasticity requires to differentiate between reversible and irreversible emissions in contrast to the deterministic version. The unconstrained (= reversible) case allows for a closed form solution but not the more realistic and constrained case. Nevertheless interesting analytical properties (e.g. about when to stop emissions, implicit conservation due to monopolistic supply) are derived and complemented by a numerical example.     

论中国寻租社会成本的量度

中国寻租社会成本的量度可以从两个不同的视角进行分析通过寻租社会成本的计量公式可以求出不包括外部性在内的中国寻租的社会成本;从外部性角度考虑,可以通过亚当·斯密的职业选择理论,抽象出一个模型来分析影响政府人选择职业的各种因素,从而剖析我国的寻租活动的社会成本.
