Children's Perceptions of Family Relationships as Assessed in a Doll Story Completion Task: Links to Parenting, Social Competence, and Externalizing Behavior

This study was designed to examine the links between parenting, children's perceptions of family relationships, and children's social behavior. Seventy‐four children (M age=6.01 years; 39 boys; 35 girls) and their parents took part in the study. Children completed relationship‐oriented doll stories that were coded for coherence, prosocial themes, and aggressive themes. Parents completed a report of their child's social behavior, a parenting scale, and a number of demographic items. Teachers also completed measures of children's social competence and externalizing behavior. Warm parenting predicted both a child's representation of prosocial themes in the doll stories and social competence, whereas harsh parenting predicted both a child's use of aggressive themes in the doll stories and a child's externalizing behavior. These findings support the idea that children are constructing models of relationships out of the early interactions with caregivers, and that they use these representations to guide their social behavior.     

Ratio-Scale Measurement with Intransitivity or Incompleteness: The Homogeneous Case

In the homogeneous case of one-dimensional objects, we show that any relation that is positive and homothetic can be represented by a ratio-scale and a unique and constant biasing factor. This factor may favor or disfavor the preference for an object over another. In the first case, preferences are complete but not transitive and an object may be preferred even when its value is lower. In the second case, preferences are asymmetric and transitive but not negatively transitive and it may not be sufficient for an object to have a greater value to be preferred. In this manner, the biasing factor reflects the extent to which preferences may depart from a maximization process.     

管理团队认知能力、行为整合对决策效果的影响机制研究

现有文献在研究团队决策效果的影响因素时,大部分关注年龄、学历等因素,较少关注非人口统计学特征。根据现有研究结果构建团队认知能力与决策效果的关系模型,利用结构方程模型进行实证研究并指出:团队认知能力的两要素能提升团队决策效果;团队行为整合被看作是团队运作过程的核心,对决策效果产生一定的正向作用,即团队的行为整合程度越高,其决策效果越好;验证行为整合在团队认知能力与决策效果之间具有中介作用。旨为丰富高阶理论、揭示认知能力对决策效果的作用提供借鉴。     

政府失效之表现、原因及对策分析

政府失效的具体表现是:产生了新的外在性,造成了新的资源浪费,形成了新的垄断,造成了新的不平等,带来了新的经济起伏波动。治理政府失效的对策是:明确政府干预行为的目的及职能范围,决策科学化、民主化,提高政府机构的办事效率,加强对政府行为的监督与约束。     

民族地区乡村经济行为模式、动机体系及其变迁研究

民族地区乡村经济中的主导经济行为模式至少存在四种类型。民族地区人们的经济行为大致有三种基本的动机体系。改革开放以来,有五种主要因素在改变着这些经济动机体系和行为模式,一是乡(镇)政府、具有准政府性质的村集体组织以及其他各种组织的推动、示范和劝导作用,二是体制改革的推动或压力,三是文化移入的诱导或冲击,四是内部创新行为的出现,五是特定文化传承的激活。     

基于非理性行为的羊群效应分析:一个简单模型

本文在序贯交易的框架内用一个简单的模型分析了证券市场上的非理性交易行为怎样引起交易者之间的羊群行为。研究结论表明:若证券市场上所有的参与者完全理性且风险中性,则市场上不会出现羊群交易行为;相反,即便在一维不确定性下,交易者的非理性交易行为可能引起羊群效应。     

流动性约束与消费行为关系的实证研究

流动性约束是指资本市场的资金流动具有单向性,流动性约束的存在可以提高储蓄水 平,降低当期累积消费. 通过三阶段生命期界的最优消费模型,证明了流动性约束的定量存在, 并通过实证检验发现,我国消费总量中受流动性约束影响的比例达到83. 46 %. 因此,增强信 贷市场的流动性,对于扩张有效需求将起重要作用.     

绿色食品信息、价值属性对绿色购买行为影响实证研究

根据EKB模型、H-S模型和消费价值模型,结合绿色食品自身特征,构建了绿色信息传播、绿色产品属性、消费者购买行为3个构面的模型。通过问卷调查,分析了绿色信息传播和绿色产品属性的直接关系程度,以及绿色信息传播、绿色产品属性对消费者购买行为的影响。主要研究结论：绿色信息传播对绿色产品属性有普遍直接影响,绿色信息传播、绿色产品价值属性对消费者购买行为有直接影响。     

群体性突发事件中政府机会主义行为的演化博弈分析

群体性突发事件成为影响当前我国社会稳定和实现现代化平稳过渡的重要因素,但是研究主要是基于实践经验的概述和总结分析上,缺少合适的理论分析工具揭示群体性突发事件的演化规律和发展特征。本文尝试运用演化博弈理论建立了地方政府部门与社会弱势群体之间的演化博弈模型,分析了地方政府部门机会主义行为导致的群体性突发事件呈现扩大化的趋势。研究结果表明:(1)如果社会弱势群体的情绪和行动尚未激化,至多停留在集体上访或集会等体制内平和的诉求手段,机会主义的地方政府将采取高压强硬策略;此时博弈均衡结果是(妥协或平和诉求,强硬);(2)一旦弱势群体中出现少数分子采取了"打砸抢"等暴力抗争的行动,由于机会主义政府转而做出较大让步,从而诱导其他弱势成员相继采取暴力抗争行动,事态反而进一步呈现扩大趋势。因此,群体性突发事件处置过程中,地方政府的机会主义行为不仅延误事件处置的最佳时机,而且直接导致了事态的扩大化。最后结合数值分析和瓮安事件案例,剖析了地方政府部门采取的机会主义应急处置措施,以及本文理论模型的适用范围。     

The Microeconomics of Efficient Group Behavior: Identification1

Consider a group consisting of S members facing a common budget constraint p'ξ=1: any demand vector belonging to the budget set can be (privately or publicly) consumed by the members. Although the intragroup decision process is not known, it is assumed to generate Pareto‐efficient outcomes; neither individual consumptions nor intragroup transfers are observable. The paper analyzes when, to what extent, and under which conditions it is possible to recover the underlying structure—individual preferences and the decision process—from the group's aggregate behavior. We show that the general version of the model is not identified. However, a simple exclusion assumption (whereby each member does not consume at least one good) is sufficient to guarantee generic identifiability of the welfare‐relevant structural concepts.
