The effects of possession- and social inclusion-defined materialism on consumer behavior toward economical versus luxury product categories,goods versus services product types,and individual versus group marketplace scenarios

The paper builds on and extends the current understanding of materialism by investigating the effects of two forms of materialism (i.e., possession- and social inclusion-defined) on consumer behavior (i.e., purchase and patronage) toward products of different categories (i.e., economical versus luxury) and types (i.e., goods versus services) in different marketplace scenarios (i.e., individual versus group). Using data partitioning on a random sample of 323 consumers to generate usable cases for three interrelated studies, the paper reports that the effects of possession- and social inclusion-defined materialism are consistently accentuated in the purchase of luxury goods rather than economical goods, whereby consumers with high levels of possession- and social inclusion-defined materialism are more likely to purchase luxury goods than consumers with low levels of possession- and social inclusion-defined materialism. However, the paper finds that possession- and social inclusion-defined materialism have no significant effects on the individual and group patronage of economical and luxury services. The paper concludes with the implications of these findings for theory, practice, and future research.     

Beer Uses and Attitudes in the Craft Era

Abstract

This article aims to address the shifts in uses and attitudes in the era of craft beer’s growth in the United States, where brand loyalty has diminished in importance; whereas the need for exploration and trial has increased in importance. These changes have implored a need for craft beer marketers to change tactics in regards to how customers learn about new beers to try, the most trusted sources and influencers of beer choice, and how to build loyalty in an increasingly brand dis-loyal customer. The gap in research being addressed is seeking to find the pathway from how traditional beer marketers have grown brands and loyal customers to where we are today, where the customer is increasingly fickle, enjoys the newness that comes from shifting loyalties, and tends to reject brands that become too strong in this arena.     

Tailored versus Mass Produced: Portfolio Managers Concurrently Managing Separately Managed Accounts and Mutual Funds

Using a matched sample of separately managed accounts (SMAs) and mutual funds (MFs) with the same portfolio manager and investment style, we find that concurrently managed MFs consistently underperform their SMA counterparts and generate more negative return gaps. Fund characteristics and liquidity betas fail to fully explain the underperformance. An event‐study analysis finds that the weights placed into top (bottom)‐performing stocks increase for existing SMAs (MFs) and negative return gaps increase for the MFs after the onset of concurrent management. We find that higher compensation collected by SMA fund managers are associated with more unseen managerial actions which positively contribute to the SMA return gap. Our results suggest that when managers concurrently manage both SMAs and MFs, they favor SMA performance over their MF performance.     

责任导向会促进年长员工知识分享吗？基于主动动机模型

全球劳动力老化的严峻形势下,探索年长员工知识分享的实现机制,对于充分开发老年人力资本、促进企业可持续发展具有重要意义。以主动动机模型为基础,探讨了责任导向对年长员工知识分享行为的作用机制与边界条件。通过线性回归和蒙特卡洛拔靴法对200份40岁以上在职员工三时点配对数据进行分析,结果表明：责任导向会通过提升年长员工的建设性责任知觉进而激发其知识分享;反年龄歧视氛围感知对这一作用过程具有权变影响。文章丰富了年长员工知识分享行为的前因研究,对企业如何积极应对职场老龄化与年长员工知识传承具有启示意义。     

国有企业高管薪酬管制与委托代理问题

由于国企高管的经营业绩难以被准确度量，加上监督约束机制不健全，高管的超额薪酬成为国企代理问题的一种典型表现，于是政府将高管薪酬管制作为应急措施来降低代理成本，缓解国企代理问题。采用双重差分法对2011—2018年A股上市公司的分析表明：第二次限薪令在有效限制国企高管薪酬水平的同时，没有对高管在职消费产生显著影响，有效降低了国企代理成本；但第二次限薪令也降低了薪酬激励效应，导致国企高管努力程度降低，由此造成的利益损失又成为新的代理成本。国企薪酬制度改革面临激励与管制的两难选择，应在国企分类改革的基础上对不同类型国企的高管采取不同的激励机制：对公益类及特殊行业的国企增强高管政治晋升激励，对竞争行业（营利性）国企则应在推向市场的同时放松薪酬管制，从而有效降低代理成本，解决国企代理问题。     

商业判断规则对中国公司法的启示

商业判断规则是美国法院对董事注意义务审查的一项重要准则，其内容是任何人要质疑董事的决策需推翻这样一个假定：董事在知悉的基础上，基于善意并相信是为公司的最大利益而做出的决策，否则法官会尊重董事的决策。商业判断规则的产生为公司的董事和他们的行为提供了在商业决策中回避风险的安全港。与之相比，我国公司法中关于董事勤勉义务的规定过于抽象，操作性不强，可以借鉴商业判断规则对其进行完善。     

Technological character,function type,and the longevity of standardized knowledge

This study seeks to determine the validity of the current de jure standards management system. The de jure standard is an important tool for innovation policy. However, its review interval has been fixed in the management system and maintained without the use of empirical analysis to guide its development. Therefore, this study (1) examines the factors that affect the longevity of the standards, and (2) outlines methods for improving how the de jure standards are managed. Results indicate that design and mark standards influence the longevity of standardized knowledge. This is notable, given that design for innovation is an emerging area of research that is commonly studied through the analysis of design patent data. Taken together, this study’s major findings are twofold. First, different technological categories have significantly different effects on longevity. Because the longevity of some technological sectors is naturally longer than others, there exists a need for a more flexible interval system. Second, the longevity of the mark and design standard is longer than the longevity of other types of standards. Both developing and developed countries utilize the de jure standard, so the policy implications of these findings are widely applicable.
