The Effects of Search-Related and Purchase-Related Mobile App Additions on Retailers’ Shareholder Wealth: The Roles of Firm Size,Product Category,and Customer Segment

Mobile channel additions have been shown to increase consumer-brand relationships, brand satisfaction towards and overall purchasing from a retailer, but what is less apparent is whether shareholders are fully rewarded for retailers’ mobile channel additions. Results from an event study on 115 announcements relating to mobile app additions of publicly traded U.S. retail firms between 2009 and 2016 indicate that the stock market responds generally positively to mobile app additions, but specifically to the two mobile app addition types. Stock market responses to search-related and purchase-related app additions are moderated by firm size, product category, and target customer age. For announcements of search-related apps, the market responds more positively to product retailers than to service retailers, and to small firms than large ones. For announcements of purchase-related apps, the market responds less positively to firms that target younger customers than firms who do not especially target them.     

Relative-to-rival corporate philanthropy,product market competitiveness,and stakeholders

Unlike most of the literature that examines the relationship between corporate philanthropy and financial performance, this study investigates the mechanisms through which corporate socially responsible behaviors produce financial outcomes. We propose that corporate philanthropy improves corporate competitiveness by eliciting positive responses from stakeholders, who assess a firm’s philanthropic contribution in relation to its rivals to determine what level of support they wish to provide to the firm. We predict that a firm’s philanthropy relative to its rivals has a positive effect on its product market competitiveness, and that this positive effect is moderated by three conditions that influence stakeholder response: stakeholder attention to philanthropy, its perceived legitimacy, and expectations of corporate giving. Our predictions are generally supported by our analyses. Overall, this paper shows that strategic philanthropy has a quantitative dimension, and firms obtain the market competitiveness associated with corporate philanthropy by integrating their rivals’ positions into their decision making.

防范合谋的激励机制研究综述

通过对合谋内涵、舍谋成因以及防范合谋的激励机制设计三个方面的国内外主要文献进行的回顾与述评结果发现，我国在防范合谋的激励机制设计方面主要存在下列问题：国内许多文献认为信息不对称是合谋的成因，但实际上合谋的成因是互惠，信息不对称只是为合谋提供了条件；现有理论主要从激励经济学角度研究防范合谋的机制设计的，但人类行为动机的产生和发展、变化是一个复杂、微妙的心理过程，仅从激励角度研究合谋问题不足以取得满意的效果。

信息的编码、抽象与会计准则——会计准则的信息空间理论诠释

本文从信息空间理论的角度出发,对会计准则的性质进行探讨。在回顾并评价传统解释的基础上,试图得出会计准则“是什么”的一个全新诠释:就静态角度看,会计准则是一种关于企业财务信息编码和抽象的规范体系,其产生根源在于为经济交易的各方提供信息交流和标准化信息转换的平台;就动态角度看,会计准则的变迁则是体系内微观经济个体基于信号发送需要而推动的内涵性变迁和跨体系交易所要求的信息环境共享推动的外延性变迁的共同结果。此外,本文还从会计准则外延性变迁的角度解析了当前各国会计准则存在重大差异的现象。     

公开市场操作与利率期限结构行为——基于混频数据信息的研究视角

在混频数据信息环境中,精准识别公开市场操作(央行政策利率)和国债收益率曲线(基准利率体系)之间的关联机制至关重要,其影响了货币政策期限结构传导的有效性。本文在混频Nelson-Siegel(N-S)利率期限结构模型框架下,引入央行政策利率,揭示公开市场操作与利率期限结构(水平、斜率、曲度)因子之间的作用机制。实证结果表明:混频数据信息条件下,引入的公开市场操作信息显著改进国债收益率曲线的拟合效果;斜率因子冲击对公开市场操作具有显著的正向影响,而利率期限结构因子对政策调控的反应不敏感。进一步研究表明,2015年以来,公开市场操作对斜率因子的影响逐渐扩大,政策利率向国债收益率曲线的传导效率得到显著提高,我国现代货币政策框架日益健全。     

城市土地出让的收益分配与土地市场效率

通过研究城市国有土地出让的收益分配和市场效率之间的关系,建立土地开发的社会决策模型,对土地出让时的七种不同收益分配模式的市场效率分别进行了分析。分析结果表明,无论是过去的协议出让模式,还是现行的基于成本或者现状价值对原土地使用者进行补偿的出让模式,土地市场都缺乏效率,而以土地开发净收益进行分成的模式能够最大化土地市场的效率。     

构建东北区域性产权交易市场的探讨

伴随着东北三省国有企业改制、重组和国有经济结构的调整，企业国有产权转让日益增多。要在短时间内完成东北国企产权的改制，以促进东北振兴大业的顺利完成，就必须加强东三省产权交易市场的建设。由此，构建东北区域性产权交易市场就有值得研究的必要。
