信用的二重性探究

人类最初产生的信用 ,是包含在公道和友谊之中的信用 ,后来才产生借贷这种经济学意义上的信用。信用同时具有伦理品性和经济品性双重属性。现代信用既具有私人物品的竞争性、排他性 ,又具有一般公共物品的非竞争性、非排他性特征 ,还具有一般公共物品所不具备的无形化及以社会道德为基础等特殊性。信用作为公共物品仍是经济品性和伦理品性的同构体     

测度政府层级条件下公共产品最优供给规模及供给效率的模型与方法

政府供给公共产品的最优规模与效率的分析是困难的，借用分级条件下政府供给公共产品最优规模的模型和政府供给公共产品的数据包络分析（DEA）模型，为量化政府供给公共产品的效率提供理论依据；同时，根据IMD测度政府效率的指标体系和国内相关的研究实践，探讨了分析政府供给公共产品的效率的具体方法，并提出了相应的政策建议。     

社会资本视角下的农村公共产品分类与供给主体责任研究

公共产品分类研究是明确其供给责任的前提,分类研究不足是我国公共产品供给责任不清的重要原因.对公共产品分类研究不仅从理论上全面明确反映了公共产品的内容与特征,而且在一定程度上确定了公共产品供给的主体责任.

香奈儿品牌形象对消费者购买意愿的影响分析

中国消费者为现阶段全球最大的奢侈品消费群体。自香奈儿进入中国市场以来,因其高贵、优雅、简约的设计风格受到中产阶级以上女性消费群体的欢迎和喜爱。在奢侈品行业中,品牌形象作为企业重要的无形资产,成为了品牌竞争的另一领域。基于上述背景,论文以“香奈儿品牌形象对消费者购买意愿的影响分析”为选题,以贝尔模型为研究基础,使用问卷调查法获取数据,运用SPSS 19.0统计软件对数据进行处理分析,并结合消费者行为学相关理论,研究品牌形象的不同变量对于消费者购买行为产生的影响。     

Punishment,counterpunishment and sanction enforcement in a social dilemma experiment

We present the results of an experiment that explores the sanctioning behavior of individuals who experience a social dilemma. In the game we study, players choose contribution levels to a public good and subsequently have multiple opportunities to reduce the earnings of the other members of the group. The treatments vary in terms of individuals’ opportunities to (a) avenge sanctions that have been directed toward themselves, and (b) punish others’ sanctioning behavior with respect to third parties. We find that individuals do avenge sanctions they have received, and this serves to decrease contribution levels. They also punish those who fail to sanction third parties, but the resulting increase in contributions is smaller than the decrease the avenging of sanctions induces. When there are five rounds of unrestricted sanctioning, contributions and welfare are significantly lower than when only one round of sanctioning opportunities exists, and welfare is lower than at a benchmark of zero cooperation.

Competitive search markets for durable goods

Summary. This paper considers a dynamic version of Akerlof's (1970) lemons problem where buyers and sellers must engage in search to find a trading partner. We show that if goods are durable, the market itself may provide a natural sorting mechanism. In equilibrium, high-quality goods sell at a higher price than low-quality goods but also circulate longer. This accords with the common wisdom that sellers who want to sell fast may have to accept a lower price. We then compare the equilibrium outcomes under private information with those under complete information. Surprisingly, we find that for a large range of parameter values the quilibrium outcomes under the two information regimes coincide, despite the fact that circulation time is used to achieve separation.

公共品供给中的政府责任

在公共品供给中,政府责任是提供它需要并且能够提供的公共品。需要提供的公共品是指在现有的资源技术条件下,达到社会效用最大化所需提供的公共品。能够提供的公共品是指征到拉弗曲线隐含的最大税收量所能提供的公共品。需要并且能够提供的公共品是指需要提供的公共品与能够提供的公共品中量较小的一方。通过比较政府实际提供的公共品与需要并且能够提供的公共品,可以评价政府在这一领域称职与否。     

技术性贸易壁垒对我国出口的影响及对策思考
