论三个级别价格歧视间的关系

本文尝试着从联合需求曲线中裂变出三个级别的价格歧视,以此揭示出其间的内在联系。个别需求曲线的加总构成了联合需求曲线,它是就每单位的消费择优录取所有消费者的保留价格,将其从高到低依次排列的,因而它既反映了“不同的人”——高端客户与低端客户的需求强度的差异,也反映了“不同的量”——高端需求与低端需求的需求强度的差异。只要能成功地将联合需求曲线按“量”与按“人”进行拆分,就可以在不同的子市场依照不同的需求价格弹性对高端客户与高端需求定高价、对低端客户与低端需求定低价。     

Uncertain lifetimes and the welfare enhancing properties of annuity markets and social security

This paper explores the implications of social security programs and annuity markets through which agents, who are characterized by different distributions of length of lifetime, share death-related risks. When annuity markets operate, a non-discriminatory social security program affects only the intragenerational allocation of resources. In the absence of private information regarding individual survival probabilities, such a program will lead to a non-optimal intragenerational allocation of resources. However, the presence of adverse selection considerations gives rise to a Pareto improving role for a mandatory non-discriminatory social security program.     

Study on the clustering of a typical industry：a case of apple industry in Shaanxi Province, China

The apple industry in Shaanxi Province is a resource-based industry; compared to the best productiveregions at home and abroad, it is advantageous in high quality as well as geographical and natural resources. Currently,big changes have occurred in the apple market supply-demand relations; long-term and comprehensive shortage haspassed; the buyer＇s market has come into being; competitions in the domestic market are fierce. At the same time, theforeign apple will impact on the domestic market, increasing competitive pressure. Foreign anti-dumping measures,green barriers and technologies restrict the exportation of the domestic apple. Based on successful experience of otherindustrial clusters, this paper analyzes the existing problems in the development of Shaanxi apple industrial cluster,combining empirical analysis, qualitative analysis and quantitative analysis, proposes specific policy recommendationsand get the conclusions. First, the characteristics of the agricultural industrial cluster are analyzed; Shaanxi appleindustry is characterized by cluster. Second, the rapid development of Shaanxi apple industrial cluster exposes someproblems. Third, we need the government to control the disorderly competition of Shaanxi apple industry.     

税务征收体制下的基本养老保险个人缴费基数:问题、机制与对策

个人缴费基数是基本养老保险制度的关键参量之一。我国现行的个人缴费基数政策主要问题在于:一是核定过程复杂且难度大,因核定不到位导致的少缴和漏缴现象突出;二是以上年度月平均工资作为当期缴费基数的规定不合理;三是以职工平均工资的60%作为缴费基数下限加重了低工资收入者的缴费负担,易对其形成制度性挤出;四是社会保险费的征管流程存在制度性漏洞。在统筹推进基本养老保险全国统筹和社会保险费征收体制改革的关键时期,完善个人缴费基数政策应以增强规范性和统一性为重点。基于个人缴费基数的"两阶段"形成机制,本文建议应考虑工资结构差异,对企业职工、机关事业单位职工和灵活就业人员分别使用排除法、列举法和定额法来核定应缴费工资;将缴费基数下限降低至各地最低工资标准;将计算周期改为与工资、薪金所得个人所得税保持一致,实现税费同步计算、同征同管。     

The “Iron Law of Paternalism” in Employee Grievances and Arbitration? A Comparison of Disciplinary and Nondisciplinary Cases

In the criminology literature, the iron law of paternalism suggests that women receive less serious sanctions in the judicial system. This examination of three years of grievance outcomes (n= 1216) and arbitration outcomes (n= 1146) tests this iron law in the context of organizational disciplinary and dispute resolutions. These data, across several levels of outcomes (win, lose, compromise), controlling for the severity of grievances (disciplinary/nondisciplinary) and arbitrations (termination/nontermination) provide no support for the paternalistic thesis. Moreover, we find no support for the paternalistic thesis with regard to either the incidence or length of suspensions as a function of gender.     

Price leadership in a duopoly with capacity constraints and product differentiation

This paper analyzes Stackelberg price leadership in a duopoly in which firms are capacity constrained and products are imperfect substitutes. Assuming symmetric substitutes, linear demand, and efficient rationing, we characterize the equilibria with an exogenously specified leader. Using the equilibrium profits derived from these games, we argue that over certain ranges of asymmetric capacities an endogenous price leader will emerge. When endogenous leadership does arise, it is the large capacity firm which is the leader. We thus provide a game theoretic model of dominant firm price leadership.Dave Furth's research has been undertaken as a part of the project Competition and Cooperation.
