医疗保险对农村居民家庭消费的影响分析--基于不同收入层级的跨地区比较

利用2009、2010农村固定观察点数据,分析了医疗保险对不同地区、不同收入层级的农村居民家庭医疗消费支出和非医疗消费支出的影响。实证结果表明：医疗保险对农村居民家庭的医疗类消费不存在显著影响,对非医疗类消费支出则存在显著的正向促进作用。分地区来看,医疗保险对东西部地区农村居民家庭医疗类消费的影响差异显著,对东中部地区农村居民家庭非医疗类消费支出的影响同样差异显著;分收入层级来看,医疗保险对家庭医疗类消费的影响在不同收入层级的农村居民家庭之间不存在显著差异,但对非医疗类消费支出的影响在不同收入层级之间差异显著。此外,商业医疗保险作为医疗保险体系的重要组成部分,对促进农村消费起到带动作用。最后,本文从加大政府补贴和完善保障机制两个方面提出政策建议以期有效降低农村居民家庭超常的预防性储蓄,促进农村居民家庭消费。     

An Exploratory Study of Financial Remittances Among Non-Resident Indians in the United States

Remittances by immigrants and temporary workers of Indian origin in industrialized countries are a growing part of India’s economy. In this exploratory study we examine the social and economic characteristics affecting the remittance pattern of working households (or families) of Indian origin residing in the United States. As most previous studies have been undertaken at the macroeconomic level, our main contribution lies in identifying the household level factors that may influence remittances. Using an online and a mail-in survey of 39 households we find some of the significant factors affecting remittances. We also validate some of the remittance-related policies of the Indian government.

农地制度变迁的机理与合约分析：生产队制和家庭联产承包责任制

家庭联产承包责任制在农业生产上的高能激励自农地制度变革以来一直被学界所推崇,但这并不意味着生产队制的低效率。为此,在否定以生产队制低效率作为农地制度变迁的解释的基础上,从发展战略转换、制度安排缺陷、农民信念及其他方面尝试性地探讨了推动生产队制向家庭联产承包责任制变迁的内在原因,并且从生产责任制形式、土地分配方式、期限结构等方面详细阐述了家庭联产承包责任制向农业产出最大化演化的过程。相应地,伴随着农地制度变迁而来的是签约主体以及合约结构的变动,因此,从合约的角度进一步研究了生产队制与家庭联产承包责任制在合约实施和劳动监督与计量上的差别,以及作为二者共同之处的合约模糊性特征,并在此基础上对家庭联产承包责任制下税费合约的性质与形式进行了具体的分析。     

跨期消费与投资理论对新古典经济学的超越

经济学理论是时代的产物,必将随着社会的发展而不断被补充、修正和完善。新一轮经济危机的爆发对新古典经济学理论提出了挑战,自由放任、少政府干预、有效需求理论、理性人假设、一般均衡理论等遭到了质疑。本文从跨期消费和投资理论两个视角出发,分析其对新古典经济学理论的超越,揭露集聚性跨期消费和投资行为的时代缺陷,为改进和完善经济理论服务,从而合理引导跨期消费和投资理论的走向,为今后经济发展提供参考。     

理性习惯偏好与居民消费行为

 经济体制改革以来，随着经济的持续快速增长中国城镇居民已经习惯于生活水平不断提高。在这样的环境中，如果一个家庭当年消费的数量和上一年相同，其幸福感就会打折扣；另一方面，消费还具有外部性，如果与他人相比自己的消费水平降低了，消费者的效用也会受到损失。因此，理性消费者的决策目标是保持消费长期稳定增长而不仅仅是消费在各个时期的均匀分配。利用1978-2008年中国26个省（直辖市）的城镇住户调查数据得到的实证分析结果显示：消费者的习惯偏好与制度环境有关。受传统计划体制影响，1990前中国城镇居民的习惯偏好具有明显的“短视”特征。1990-2008年的估计结果则支持了理性习惯形成假设。即内部习惯形成导致了边际消费倾向明显下降，并且消费攀比是理性的。     

服务公平性对储户与银行之间关系的影响

作者在某银行广州地区的15个营业点对储户进行了一次问卷调查,探讨服务公平性对顾客与企业之间关系的影响。数据分析结果表明,结果公平性、程序公平性、交往公平性和储户感觉中的软、硬质量是同一个高阶因子的子因子,储户在正常服务环境中感知的服务公平性影响储户的消费情感和储户对本次消费经历的评估(服务质量、消费价值、储户的满意感),进而影响储户与银行之间的关系(信任感、储户与服务人员的人际关系纽带、储户与银行的感情纽带)和储户的行为意向(再购意向和口头宣传意向)。     

中国能源消费静态依赖与动态发展——基于30个省市数据综列协整分析

本文以我国30个省市为横截单元、以1995-2005年时序数据组成综列数据,建立我国省市能源消费的综列协整模型,通过综列单位根和综列协整检验,结果表明,我国各省市的能源消费与经济增长和能源效率之间存在长期均衡。基于这一结论,揭示各省市能源消费静态依赖与动态发展特征,并给出政策建议。     

The demand for social interaction

In this paper social interaction is modeled as a consumer good. A model of household production is employed to derive the demand for social interaction. The model shows that the demand for social interaction is a function of its price, the price of other goods and income. The theory is tested with data from the General Social Survey and the results show that social interaction can be explained as the consequence of utility maximizing behavior by individuals. These results are in contrast to social capital theorists who have attributed these changes to factors such as increased community heterogeneity.     

Use of time and preferences for time allocation among urban,employed, married women

This study examines the relationship between employed wives' preferences for household production time, employment time, leisure, and their actual time use. A random sample of 235 employed, married women estimate their time use on an average weekday and weekend day in 13 activities and indicate their preferences for time in those activities. Hierarchical multiple regression procedures are used to examine the relationships between actual and preferred time use. Weekday employment time is not related to preferences for more or less time in household production but wives allocating more time to employment want to spend less time at that employment and more time in leisure. Weekend employment time is related to preferences for more time in leisure, child care, and other household work. Time spent performing household work is not related to preferences for more or less time in any activity except the desire for more leisure time on weekends.Ann Renigar Hiatt is Assistant Professor in the Department of Human Services, College of Education and Allied Professions at the University of North Carolina at Charlotte, Charlotte, NC 28223. Her research interests include employed women's time allocation, time pressures, and use of time management strategies. She received her Ph.D. from the University of North Carolina at Greensboro.Deborah D. Godwin is Associate Professor in the Department of Housing and Consumer Economics at the University of Georgia, Athens, GA 30602. Her research has focused on husbands' and wives' time allocation to household production, the effects of women's employment on family economic functioning, and family financial management.

嘉庆朝内务府人参变价制度的新变化

乾隆朝内务府确立了人参变价制度,这成为其重要的财源。嘉庆时期,其人参变价在变价途径、变价价格等方面出现了一些新的变化。这些变化的出现是嘉庆皇帝统治政策调整的结果。它有着极为恶劣的影响：不仅使得内务府加剧了对两淮盐政的经济掠夺,而且进一步破坏了东北的生态平衡。这是道光朝人参变价困境的重要因素之一。
