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.     

DO FIRMS SEEK A TARGET BOARD STRUCTURE? EVIDENCE FROM THE POST‐SOX PERIOD

We investigate whether firms restructure board composition to align with changes in their contracting environment. Board size and independence increase with firm complexity, consistent with theoretical predictions. However, the hypothesized negative relation between board independence and information costs is evident only for firms completing acquisitions. Furthermore, board independence increases to offset increases in CEO power in a sample of firms making acquisitions, but decreases when CEO power increases in a large cross‐section of firms. We conclude that after the Sarbanes–Oxley Act of 2002, firms face constraints adjusting to target board structure, but these constraints can be mitigated by a shock to the contracting environment via acquisition.

辽西北地区农业干旱危险性评价与区划

[目的]开展农业干旱危险性评价与区划研究,为辽宁省西北地区农业防旱抗灾工作提供科学依据。[方法]文章根据联合国国际减灾战略署(ISDR)对农业干旱危险性的定义,分析了构成研究区作物干旱危险性的致灾因子和孕灾环境因子,采用层次分析法确定了各因子的权重,构建了研究区农业干旱危险性评价指标和模型。以2009年为例,通过利用降雨、土壤、农业生产类型及地形等数据计算了辽西北地区农业干旱危险性评价指数,利用自然间断点法分级干旱危险性评价指数,并借助GIS技术,绘制研究区农业干旱危险性等级区划图。[结果] 2009年作物生长期间研究区农业干旱危险性由高到低排列为:朝阳市葫芦岛市锦州市阜新市铁岭市沈阳市。[结论]辽西北地区农业干旱危险性等级区的划分,能够帮助政府管理部门为面临干旱威胁不同的区域建立适当的防灾方法和有效的应急预案。

甘孜州农牧区县域发展水平综合评价与特征分析

[目的]对甘孜州各县市的发展状况进行研究探讨,为区域可持续发展策略的制定实施提供科学依据,对提升县域发展水平和发展质量具有重要意义。[方法]建立涵盖经济、社会、资源环境三大模块共计24项指标的评价体系,选取发展较快的2007—2014年为研究时段,运用极差法、改进熵值法、耦合协调度模型与GIS工具,对甘孜州各县市的发展水平进行综合评价与分析。[结果](1)全州综合发展水平指数平均值为0. 500 8,发展水平整体较低,其中康定市得分最高,石渠县最低,县市之间呈现两级分化。(2) 2007—2014年全州综合发展指数平均增幅0. 262 6,年均增速13. 77%,所有县市均处于上升过程,但县市之间增速不一,发展差距逐步扩大。(3)全州发展协调度平均值为0. 390 5,协调度较低,各县市均处于轻度失调或濒临失调水平。(4)发展水平、活力、协调度较高县市均集聚于州东部和南部,尤以东路片区最为典型。[结论]下一阶段需依据各县市实际,立足优势,制定实施合理的发展规划,缩小区域差异,提升综合发展水平。
