Cournot Oligopoly Conditions under which Any Horizontal Merger Is Profitable

Findings in economic theory suggest that horizontalmergers involving firms with aggregate market shareless than 50% are unlikely to be motivated by theconsequent reduction in competitivity. The resultsarise because, absent cost efficiencies, quantity-settingfirms in small mergers are impoverished by the merger.We demonstrate that this conclusion is a consequence ofthe strong restrictions imposed on the demand function,and we identify a well-behaved demand function suchthat any set of merging firms benefits from the reductionin competition even when there are no cost efficiencies.     

“唐斯定律”的对城市道路管理方式的启示——以上海为例

近年来，我国城市纷纷采用供给方管理的方式，通过增加道路来缓解民用汽车迅猛增长所导致的交通拥堵。在这样的情况下，研究城市道路管理的方式的合理性具有突出的理论与现实意义。本文通过对城市道路的提供方式与提供数量的分析，认为：基于城市道路消费的特殊性，其供给方管理导致的诱增交通在长期会使交通状况更加恶化，与“唐斯定律”相符。随后通过对上海地区的实证研究从客观交通状况的演变及城市道路使用者的主观需求变化角度分别对该结论作进一步验证。

Critical mass of users versus critical mass of services in a multiproduct information service system

In this paper we study the economic behaviour of the suppliers of a set of advanced telecommunications services with a joint adoption cost (common access facilities, learning process, etc.). In fixing the two-part tariffs for their services the suppliers have to share the burden of leaving to the users a surplus sufficient to cover the adoption cost. The lack of coordination in supplying a critical mass of services or in the pricing decisions has high changes to result in suboptimal or unviable diffusion of the new technology as a whole. We present a static optimization model of user behaviour, and derive access and usage demand with a two-part tariff and a joint adoption cost. We compare noncooperative and cooperative market equilibria in a duopoly with perfect information; finally we discuss the extension of our analysis to the case of imperfect information in a dynamic setting.     

Poverty and fat consumption: Education poor or income poor?

In this paper, we question the role of added fats on health disparities in the French case and its policy implications. Since low-status populations are proven to have more nutritional pathologies, can we evidence fat consumption specificity in poor populations? We first verify the strong sensitivity of fat consumption to income and education, criteria which both characterize deprived populations. We estimate a demand system taking into account the selection issue. For this we propose a modification of the Shonkwiler and Yen's procedure which, unlike Heckman's, allows participation on every market of products to be controlled for. We use the latter procedure on a set of seven fat categories which have different, including opposite, health attributes. Our results show that segmentation following income and/or education essentially affects price elasticities. This offers different perspectives for health policies. Controlling fat consumption through prices appears easier among low-income households than among low-education households.     

An experimental approach to valuing new differentiated products

An experimental store was created to evaluate initial demand for locally produced and guaranteed tender steak products as a more realistic alternative to contingent valuation (CV) and dichotomous-choice experimental methods. Strengths of the approach are incentive compatibility, a realistic consumption set, and a familiar choice environment. Consumers selected among USDA Choice, premium quality, lean, guaranteed tender and locaily produced strip steaks. A double-hurdle count data model indicated initial willingness-to-pay (WTP) for locally produced steak comparable to prior CV results, but demand was highly elastic. Demand for premium quality steak crowded out demand for the guaranteed tender product, contrasting with prior dichotomous-choice experimental results.     

以财富管理为着力点服务浙江经济转型升级

浙江省经济转型将迎来巨大的财富管理需求,这为银行业发展财富管理业务提供了良好契机.同时,开展财富管理银行业务也是商业银行打破同质化竞争、辅助产业资本走出去、实现自身战略转型的必由之路.在浙商业银行实现财富管理转型,必须从传统的资金提供者向综合金融服务商转变,可以从产品创新、品牌塑造、新兴产业、中小企业、信息技术和风险控制六个方面入手.同时,政府和监管机构也应加快完善法律法规,鼓励金融创新,搭建行业交流平台.     

农村资金互助社可持续发展的策略取向研究

面对分散的小额贷款市场,农村资金互助社拥有内在的组织和制度上的优势.但在现实中,其生存发展尚面临资金来源缺乏、信贷风险转移机制缺失、外部政策环境待完善等因素制约.为增强农村资金互助社的持续发展能力,需要建立其与正规金融机构的资金联结机制,深化与农民专业合作社的合作,健全自身的管理,并优化政府的监管安排.     

关于我国货币需求函数研究的几点看法

本论文在对过去20年我国货币需求甬数相关研究的文献总结后发现:货币需求函数研究是个传承与分化的过程;"三分法"不利于货币需求函数研究的模型表达;当前文献中广泛使用的制度变量替代形式可能存在严重缺陷;货币层次的传统分类方法使货币需求函数稳定性检验产生误差.论文由此提出建立目标取向基础上的货币需求甬数体系.
