Combining “real effort” with induced effort costs: the ball-catching task

We introduce the “ball-catching task”, a novel computerized task, which combines a tangible action (“catching balls”) with induced material cost of effort. The central feature of the ball-catching task is that it allows researchers to manipulate the cost of effort function as well as the production function, which permits quantitative predictions on effort provision. In an experiment with piece-rate incentives we find that the comparative static and the point predictions on effort provision are remarkably accurate. We also present experimental findings from three classic experiments, namely, team production, gift exchange and tournament, using the task. All of the results are closely in line with the stylized facts from experiments using purely induced values. We conclude that the ball-catching task combines the advantages of real effort tasks with the use of induced values, which is useful for theory-testing purposes as well as for applications.     

外部环境、资源拼凑与“军技民用”新产品开发关系研究

基于资源拼凑理论视角,运用扎根理论对传统军工企业“军技民用”新产品开发过程进行探究,并探索外部环境、资源拼凑对“军技民用”新产品开发的作用机理。结果发现：“军技民用”新产品开发包括信息获取、技术选择、技术再造3个过程;资源拼凑是“军技民用”新产品开发的有效措施;外部环境对资源拼凑开发“军技民用”新产品过程具有调节作用。     

R&D, risks and overreaction in a market with the absence of the book-to-market effect

Prior studies document that the book-to-market (BM) effect is absent in the Taiwan stock market. Using Taiwanese data covering from 1991 to 2006, we show that, after controlling for the size effect and the Fama and French's (1993) risk factors, the BM effect only exists for those firms with low R&D intensity essentially because these stocks suffer less from investors’ underreaction to R&D investment. The BM effect arises primarily from fundamental reversals acting as a proxy for investors’ overreaction.     

安徽省亳州市小麦产业现状与发展策略研究

目的 亳州市位于黄淮麦区,是安徽省小麦种植面积第二大地市,亳州小麦产业化发展对安徽省至关重要,总结亳州小麦产业发展现状,分析其存在的主要问题,为亳州小麦产业化发展提供建议。方法 文章通过对亳州小麦产业和加工企业进行实地调查,委托亳州市农业局和农业科学院组织主题为小麦生产和消费的座谈会,收集小麦种植品种、种植面积以及产量等相关数据,分析小麦产业化发展现状及现存主要问题。结果 亳州市形成以优质强筋小麦、中强筋小麦、中筋小麦为主,弱筋小麦为辅的种植结构,2019年优质专用小麦种植面积占小麦总面积69%。现有规模化面粉企业28家,合计年加工小麦约200万t,消费当地近60%的小麦。小麦产业发展过程中存在“农业合作社规模较小,种植规模和专业技能不足”“订单农业较少,小麦优质不优价”“面粉企业规模较小,下游食品加工企业少”“产业链间的融合不够紧密”等问题。结论 提出“构建大规模小麦加工体系,发挥龙头企业的产业带动作用”“发展农业专业合作组织,实现规模化、标准化、专业化种植”“研发优质品种配套栽培技术,实现良种良法”“打造优质专用小麦生产示范区,培育区域品牌”等策略建议。     

Hedonic models and air pollution: Twenty-five years and counting

This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper.

高科技企业研发投入同群效应研究

探讨高科技企业研发投入的同群效应,特别是企业面临的市场环境不确定性,以及体现制度环境的知识产权保护对高科技企业研发投入同群效应的影响。实证分析沪深A股2009—2017年高科技上市公司数据,结果表明：①高科技企业研发投入存在显著的同群效应;②环境不确定性显著负向调节高科技企业研发投入的同群效应,即环境不确定性弱化了企业研发投入的行业趋同;③知识产权保护显著正向调节高科技企业研发投入的同群效应,即知识产权保护强化了企业研发投入的行业趋同。结论丰富了企业研发投入同群效应研究成果,为考察企业所处外部市场与制度环境对企业研发投入同群效应的影响提供了新视角。     

Do funding sources matter?: The impact of university-industry collaboration funding sources on innovation performance of universities

ABSTRACT

The nature of funding sources for university-industry collaboration (UIC) has gradually changed, which may motivate universities to pursue different goals. Therefore, a question arises concerning whether and how funding sources influence the innovation performance of universities. This study explicates this relationship by using organisational control theory. Results of structural equation modelling using partial least squares based on a sample of 146 Taiwanese universities revealed that both governmental and industrial funding facilitated UIC management mechanisms and regulation implementation, which subsequently influenced the innovation performance of universities. Moreover, governmental funding has a greater impact on implementing UIC regulations and industrial funding has a greater impact on building UIC management mechanisms. The results also revealed that only industrial funding exerts a positive influence on the innovation climate of a university. Policy implications are discussed at the end of this paper.
