医疗决策情景下医生利他性测量的实验经济学研究

随着实验经济学、行为博弈论的发展,传统经济学中的自利假设受到利他倾向的挑战。利他性在医疗决策中体现为医生行为偏离个人利益最大化,关注患者健康福利,被认为是医生绩效和医疗服务质量的关键决定因素之一,对公益性导向和满足社会公众利益最大化目标的落实具有重要意义。但是利他性难以测量影响了对医生利他性的研究和有效激励机制的建立。本研究基于显示偏好原理并采用独裁者博弈为基础设计的受控实验室实验模拟医生医疗决策情景,根据医生决策结果,分别基于医生效用函数计算和运用随机效用模型估算医生的利他性。结果显示医生决策过程中对患者健康效益给予了正向权重。医生的利他性存在异质性。基于医生效用函数计算的利他性均值为0.82,表明医生对患者健康效益的权重为82%。96%的医生利他性大于0.5,50%的医生利他性大于0.85。运用随机效用模型估算的利他性(患者健康效益与医生利润的边际替代率)为1.078>1,49%的医生边际替代率大于1,说明相比个人利益医生更加重视患者健康效益。两种方法下测量的利他性显著正相关(Spearman’s ρ=0.715, p<0.001)。提示本研究应用的医疗决策情景下利他性的测量方法可实现医生利他性的量化,基于两种方法测量的医生利他性可以相互印证。     

Distinguishing between the impact of social media public and private compliments on customers’ future service recovery expectations

We seek to explore whether customers’ levels of service recovery expectations differ across customers who, prior to the service failure, publicly complimented the firm on social media and customers who, in advance of the service failure, privately complimented the firm on social media. We explore these differences in terms of satisfaction with the service provider and willingness to go back to the service provider. We conduct an experiment to test the research hypotheses. Our study results show that customers who complimented the service provider publicly (relative to privately) on social media in advance of a service failure require a higher level of service recovery to be satisfied with the service provider and go back to the service provider. Further, these effects are partly moderated by customer loyalty and social media usage intensity.     

获益不对称情景下的群体间合作行为研究

掌握获益不对称群体间合作行为规律可为大量的此类合作实践提供指导。在群体内和群体间过程不能割裂的认识下,群体间自发合作本质上是个体、个体所在群体、群体间所形成嵌套社会困境下的全局公共品贡献行为。通过行为经济学理论、嵌套社会困境多公共品实验室实验对获益不对称群体间合作行为进行分析和检验发现:（1）合作环境具有宽归集、内群体偏向行为特点;（2）在交互中,不公平厌恶和互惠两类条件合作的出现和叠加使此类合作从开始到持续不同于获益对称情形;（3）高水平、更稳定的群体间合作可出现于温和程度的不对称情形。该结果表明行为因素可为促进获益不对称群体间合作实践提供新途径。     

吉林油田电能计量系统容灾方案的研究

吉林油田电能计量系统存储、分析的大量数据对于吉林油田有着重大意义,吉林油田的很多日常业务都以这些数据为基础,如果因为一些自然灾难或者人为原因而造成数据损坏或者丢失,将会大大降低工作效率,丢失的数据还要经过最原始的人工抄表进行填补。目前这套系统的数据只是定时的进行人工备份,像这样的繁琐的数据备份即耗费人力物力而且在数据在意外丢失的情况下恢复的数据量又难以得到保证,这样很可能会造成巨大的不可弥补的损失。吉林油田电能计量系统容灾方案旨在为吉林油田电能计量系统提出一个完善的容灾系统。这样,即使吉林油田电能计量系统出现意外,容灾系统也会立即恢复数据,为系统正常运转提供了保障。

Corruption in public service delivery: An experimental analysis

To improve our understanding of corruption in service delivery, we use a newly designed game that allows us to investigate the effects of the institutional environment on the behavior of service providers and their monitors. We focus on the effect of four different factors: whether monitors are accountable to the service recipients, the degree of observability of service providers’ effort, the providers’ wages and the providers’ professional norms. In accordance with theory, we find that service providers perform better when monitors are elected by service recipients and when their effort is more easily observed. However, there is only weak evidence that service providers perform better when paid more. Monitors are more vigilant when elected and when service providers are paid more. Playing the game with Ethiopian nursing students, we also find that those with greater exposure to the Ethiopian public health sector perform less well, either as provider or as monitor, when the experiment is framed as a public health provision scenario, suggesting that experience and norms affect behavior.     

最低工资标准提升的就业效应——一个基于自然实验的经验研究

本文以最低工资标准提升作为自然实验,应用回归调整的差中差方法分析了最低工资标准提升对青年和中年低技能劳动力就业的影响。研究结果表明,最低工资标准提升对低技能群体中的男性和青年女性的就业没有产生显著影响;但对低技能群体中的中年女性就业却产生显著的消极影响,且最低工资标准提升幅度越大,对就业的消极影响越大。因此,政府适当的提升最低工资标准将有助于低技能劳动力整体工资水平的增长。

通过构建大企业集群自主创新模式选择动力系统模型,探讨了6种自主创新模式动力要素构成,并根据集群生命周期理论,分析了不同生命周期阶段的大企业集群特征,提出后发优势下大企业集群自主创新推进模式：产生阶段宜采取基于技术引进的自主创新和官产学研合作创新;成长阶段宜采取基于跨国技术联盟的自主创新、集群大企业合作自主创新和适度的原始自主创新;成熟阶段宜进行原始自主创新和基于跨国并购的自主创新;衰退阶段原产业宜采取集成创新,新产业宜采取灵活的自主创新模式。最后,以青岛家电大企业集群为典型案例进行分析,验证了相关结论。     

INTRA‐HOUSEHOLD EXPERIMENTS: A SURVEY

Experiments with family groups are rare, but since many decisions are taken at the household level or occur within the household it is an important area to investigate. This paper provides a survey of the recent experimental work on intra‐household decision‐making. I discuss some of the challenges involved in doing experiments with couples and families and consider major areas that remain yet to be explored. While general themes from the research are still emerging, four results repeatedly occur: (1) the absence of efficiency in intra‐household decisions; (2) joint decisions that are not a convex combination of individual decisions; (3) individual behaviour is affected by opportunities for hiding actions from spouses and (4) deviations from standard models of microeconomics in line with those seen in the anomalies literature of individual decision‐making.
