The Transition of Thoughts on Grain Control in the Qing Dynasty:A Survey of the Great Debate on the Ever-Normal Granary and Grain Prices in 1748

The ever-normal granary system was an official granary management system in ancient China.Throughout its existence,the system functioned as a major means of adjusting the price of grain and provided disaster relief.Few studies on the system touches upon the relationship between grain price fluctuation and the development of the grain market,or the ever-normal granary system and its related economic school of thoughts.Starting with the development of the grain market and the relationship between the price of grain and grain reserves,and through a systematic review of the debate on the ever-normal granary system and grain prices among high-level officials of the Qing government in the 13th year of Emperor Qianlong’s reign(1748),this paper analyzes the historical process and reasons for the change in thoughts on the ever-normal granary system and discusses the historical path of how economic phenomenon gave rise to the clash of economic thoughts that influenced the evolution of this economic institution.     

How small service failures drive customer defection: Introducing the concept of microfailures

Service that falls below customer expectations is framed as a service failure. While many researchers have investigated service failures, they have tended to focus on large service failures. This is likely because large failures are more noticeable by firms and more likely to prompt customer complaints than small failures. However, we argue that smaller service failures can cause as much damage as larger failures, and in some cases even more. We introduce the concept of service microfailures, which we define as instances when a customer’s expectations go unmet in some small way. While minor in isolation, repeated service microfailures that go unnoticed and unrecovered can compound in effect and drive customer defection. For this reason, we propose that service microfailures are a potentially much larger managerial problem than they may appear on the surface. In this article, we conceptualize microfailures as a distinct form of service failure and outline the mechanism through which they cause damage. We then develop a multifaceted approach through which managers can detect, repair, and prevent service microfailures.     

恩格尔系数失灵的若干影响因素分析

文章所探讨的恩格尔系数失灵,是指恩格尔系数在中国现实情况下被低估而不能正常反映现实经济情况的现象。文章认为,导致恩格尔系数失灵的因素包括房地产价格上升、社会保障制度不健全、收入分配差距扩大、食品安全问题等,这些因素都会降低居民食物的显性支出。文章提出,恩格尔系数的划分标准是居民生活质量重要的评判依据,但不是惟一的评判依据。在实际应用中,恩格尔系数须结合GDP、人均GDP、基尼系数等指标一同搭配使用,才能更好的作为测定居民生活水平的依据。政府应通过宏观经济政策的规制,提高恩格尔系数对现实经济运行的解释力,弱化并消除恩格尔系数失灵的现象。     

面向再制造业市场失灵问题的协同方案研究

鉴于再制造在资源效率、能源节约、环境保护等方面具有的优势,近年来,大力推进再制造业的发展,成为学术界和政府相关部门的共同呼声.然而,现实中,再制造业的发展,尤其是在起步阶段,通常面临着交易成本、信息不对称以及外部性等障碍,即市场失灵问题.文章首先从资源效率的视角理解再制造的内涵,其次探讨成功的再制造业所必需的关键要素,然后对再制造业发展过程中的市场失灵问题进行归类,最后以构建“政府—企业—行业协会”的协力伙伴关系为视角,提出矫正市场失灵的协同方案.     

中小企业财务预警实证研究—来自上市公司的经验证据

文章采用了统计方法中的因子分析法,通过对我国中小板上市公司财务失败状况的实证研究,建立了中小板上市公司财务预警模型——主成分模型,并通过选择的样本指标,初步确定了企业财务状况评价区域,并对模型的有效性进行了检验。结果证明所建立的模型对中小板上市公司具有预警作用。     

A Kinked-Demand Theory of Price Rigidity

I provide a microfounded theory for one of the oldest, but so far informal, explanations of price rigidity: the kinked-demand curve theory. Kinked-demand curves arise when some customers observe at no cost only the price at the store they are at. At the microlevel, the kinked-demand theory predicts that prices should be more likely to change if they have recently changed, and more flexible in markets where customers can more easily compare prices. At the macrolevel, it captures a part of the inflation/output trade-off that is not shifted by inflation expectations and therefore persists in the long run.     

试论《太平经合校》中“师策文”与哀帝建平四年的宗教运动之关系

通过对比考察《太平经合校》中的"师策文"与史籍所载的汉哀帝建平四年(公元前3)的宗教运动所表现出的诸多特征,认为《太平经合校》中的"师策文"应是汉哀帝建平四年(公元前3)宗教运动的行动纲领,在甘忠可的《包元太平经》中应已存在。此次宗教运动表明民间道教团体至少是在西汉哀帝之时便已如火如荼地发展起来了。     

政府竞争、规制失效与垄断行业高收入来源探析——以中国电力产业为例

本文通过建立电力产业规制模型来探讨垄断的电力产业促进中国经济增长的具体机制。我们发现,相对于无规制的独家垄断状态,规制者通过降低垄断者的电价和利润来实现经济增长的目标,但是不完美监督则造成了"双赢互换型"规制失效和小工商业用户对耗电大户的交叉补贴,这构成了电网高收入的主要来源。经验证据进一步证明了本文提出的理论命题,最后,我们总结提出了中国的电力产业规制理论,并对现行的电力产业改革路径进行了反思。     

Inducing Employees to Leave: A Comparison of Four Severance Options

This study examines the demographic, economic, and psychographic characteristics of 324 blue‐collar workers who were offered four options for either retirement or severance from the organization. Consistent with previous research, individuals who accepted retirement options have more organizational tenure and believed that the packages would provide stable financial futures. A key finding for those who accepted the nonretirement options is that comparable employment would be available. The study concludes with research limitations and suggestions for future research.
