Signaling to Partially Informed Investors in the Newsvendor Model

We analyze a signaling game between the manager of a firm and an investor in the firm. The manager has private information about the firm's demand and cares about the short‐term stock price assigned by the investor. Previous research has shown that under continuous decision choices and the Intuitive Criterion refinement, the least‐cost separating equilibrium will result, in which a low‐quality firm chooses its optimal capacity and a high‐quality firm over‐invests in order to signal its quality to investors. We build on this research by showing the existence of pooling outcomes in which low‐quality firms over‐invest and high‐quality firms under‐invest so as to provide identical signals to investors. The pooling equilibrium is practically appealing because it yields a Pareto improvement compared to the least‐cost separating equilibrium. Distinguishing features of our analysis are that: (i) we allow the capacity decision to have either discrete or continuous support, and (ii) we allow beliefs to be refined based on either the Undefeated refinement or the Intuitive Criterion refinement. We find that the newsvendor model parameters impact the likelihood of a pooling outcome, and this impact changes in both sign and magnitude depending on which refinement is used.     

中国制造业产业生命周期研究———基于１９９３—２０１４年数据的分析

中国制造业面临着日益严峻的资源和环境约束,制造业产业如何在转型升级、创新驱动中合理定位和选择发展道路尤为重要。通过中国制造业产业生命周期分析,明确制造业产业发展阶段,可以有效制定相关政策予以促进或抑制。因此,运用产出增长率法、产业生长曲线法、综合指标分析法等方法,基于１９９３—２０１４年的制造业产业数据展开实证检验。结果发现,基于３种不同方法所得结论基本一致：１／３的制造业产业仍然处于快速成长阶段,但半数制造业产业已经处于成熟期,少数则处于衰退期。针对处于不同生命周期阶段的产业,可分别采取创新发展、转移产能等策略。     

中国语境下主流媒体传播力评估模型及指标体系的构建

能力建设与关系建构:社会工作的基本目标

社会工作是什么的问题已成为社会工作界的百年历史难题与学科基本问题,该问题可以通过社会工作的目标进行解答.具体而言,社会工作的基本目标在于服务对象的能力建设和社会关系建构.能力建设是指通过充分挖掘受助者的潜力与能动性,使其获得独立面对生活困境的各项能力,实现受助者“自助”;关系建构则是通过扮演“资源链接者”的角色,帮助受助者建构足够的关系资源来助其渡过生活难关,实现受助者“他助”.能力建设与关系建构相互依赖、不可分割,受助者的能力是其社会关系运作的基础,而社会关系则是能力得以发挥的手段.只有兼顾二者,社会工作“助人自助”的总目标才能得以实现.     

"三农"与农村资金融量问题研究

笔者在阐述“三农”与我国农村资金融量相互关系的基础上,对我国农村资金融量问题进行了理论和实证研究,得出的结论是:在中国农村存在巨大的资金融量缺口,并有逐年扩大的趋势,这种缺口在中国农村形成有其深刻的历史、经济和体制根源。为此,提出了对我国农村经济和金融体制进行若干重大变革的政策建议。     

乡村教师文化回应性教育能力的理论阐释及实践探索

文化回应性教育能力主要包括态度与责任、认识与理解、技能与实践、反思与批判四个维度,以及乡土情怀、乡土知识、文化回应性教学能力、文化回应性课程能力、文化回应性评价能力、文化回应的敏感性六要目。目前,乡村教师责任担当存在理性与感性的相互割裂、乡土知识的认知与理解较为窄化零散、文化回应性教学设计和实施流于形式、文化回应性课程资源转化有限且碎片化、文化回应性评价内容和方法单一、文化回应性反思批判的敏感性薄弱等问题。基于此,需营造滋养乡村教师情感的乡村文化生态,构建文化回应的教师教育课程教学体系,聚焦乡村教育的实践情境搭建支持体系。     

Evaluation capacity building in the nonformal education context: Challenges and strategies

Policymakers’ demand for increased accountability has compelled organizations to pay more attention to internal evaluation capacity building (ECB). The existing literature about ECB has focused on capacity building experiences and organizational research, with limited attention on challenges that internal evaluation specialists face in building organizational evaluative capacity. To address this knowledge gap, we conducted a Delphi study with evaluation specialists in the United States’ Cooperative Extension Service and developed a consensus on the most pervasive ECB challenges as well as the most useful strategies for overcoming ECB challenges. Challenges identified in this study include limited time and resources, limited understanding of the value of evaluation, evaluation considered as an afterthought, and limited support and buy-in from administrators. Alternatively, strategies found in the study include a shift in an organizational culture where evaluation is appreciated, buy-in and support from administration, clarifying the importance of quality than quantity of evaluations, and a strategic approach to ECB. The challenges identified in this study have persisted for decades, meaning administrators must understand the persistence of these issues and make an earnest investment (financial and human resource) to make noticeable progress. The Delphi approach can be used more often to prioritize ECB efforts.
