从信息化人力资源管理到大数据人力资源管理的演进——以腾讯为例

当前大数据人力资源管理的研究日益增加,然而大多数文章中所谓的大数据人力资源管理仍是对信息化人力资源管理概念的修补,少有研究界定信息化人力资源管理和大数据人力资源管理的区别和演进关系.本文基于资源基础观,从有形、无形和人力等资源的动态演进出发,对腾讯人力资源数据管理演进过程进行探索性案例研究.研究发现:大数据人力资源管理在信息化人力资源管理的基础上有了质的变化,大数据人力资源管理能够为组织带来竞争优势.研究进一步归纳出大数据人力资源管理与企业竞争优势的逻辑模型.     

资本结构与股权价值关系研究

本文通过理论分析和实证检验发现净资产收益率与资本结构之间的关系依赖于整体宏观经济环境和公司特征变量,当公司治理水平上升、增长机会增大、赢利能力增强、行业竞争程度下降时,净资产收益率与资本结构之间的相关系数上升。这表明净资产收益率与资本结构之间的关系并非绝对的正相关或负相关关系,有助于解释为什么学者在研究两者之间的关系时结论大相径庭。因此,提升经济发展水平、加强对投资者的保护、建立基于资本供求关系的利率体系有助于优化资本市场资本配置的基础性功能。     

“对症下药”还是“避重就轻”:环境违规企业补救行为研究

在践行绿色发展理念的背景下,研究环境违规企业补救行为对加强环境治理具有重要意义。文章采用印象管理理论将企业环境违规后用来修复组织形象的策略分为"对症下药"（积极进行绿色创新实现绿色转型）和"避重就轻"（实行其他社会责任转移公众注意力）两方面,将"避重就轻"分为外部社会责任与内部社会责任,利用2013-2017年中国A股上市的制造业企业数据,实证检验环境违规的经济后果以及企业的后续补救方式,并进一步探究其补救行为地区异质性。研究结果表明：环境违规行为会降低企业价值,说明投资者进行投资决策时已逐渐将企业的环境表现纳入考量;但违规企业没有通过绿色创新实现绿色转型,告知公众有关公司环境表现和行为的改变,而是通过加强其他社会责任以转移公众注意力,且更偏向于加强外部社会责任,内部社会责任反而降低了。进一步研究表明环境违规企业"对症下药"行为在西中东三个地区之间并无明显差异,但"避重就轻"行为存在地区异质性,即主要发生在经济较为发达的东部地区。文章提供了环境违规企业重获合法性的可能途径,发现面临合法性压力,企业会选择性参与社会责任。这为深化环境管制成效提供了指引,并在一定程度上揭示了企业社会责任的"伪善"。     

从美国次贷危机看金融创新的风险管理

该文指出美国次贷危机的根源是对金融创新的风险管理不到位,文章分析了金融创新的特征以及市场参与者对金融创新的风险意识淡薄的现状,指出美国次贷危机的教训在于金融机构应充分重视金融创新中的风险管理,而监管机构对金融创新的风险监管则是业务发展和市场稳定的有力保障;最后文章对如何加强我国金融创新的风险管理提出相关的意见和建议。     

Information acquisition,referral, and organization

Each of two experts may provide a service to a client. Experts' cost comparative advantage depends on an unknown state, but an expert may exert effort to get a private signal about it. In a market, an expert may refer the client to the other for a fee. In equilibrium, only one expert exerts effort and refers, and the equilibrium allocation is inefficient. Referral efficiency can be restored when experts form an organization, in which a referring expert must bear the referred expert's cost. However, the referred expert shirks from work effort because of the lack of cost responsibility.     

Deregulation,Pricing Strategies,and Claim Behavior in the Taiwan Automobile Insurance Market

Stringent pricing regulations have long been in effect in the Taiwan automobile insurance market. In April 2009, a pricing deregulation was adopted, enabling insurers to establish their own auto insurance premium rates. This study examines the effects of deregulation in terms of three hypotheses that we propose pertaining to market shares, loading factors, and last policy month claims. The quantitative analysis results show that pricing deregulation prompts insurers to lower their rates. The effects of deregulation for insurers are determined by not only the decision to deduct premiums and the deduction percentages, but also by policy type.     

Corporate social responsibility and provision of trade credit

In this article, we identify and examine three different views of corporate social responsibility (CSR) and the relationship between CSR and firms’ provision of trade credit. The trust view of CSR argues that CSR and trade credit provision are related positively, because CSR, as a trust-enhancing device, complements the incomplete contract nature of trade credit. The CSR literature shows that CSR firms tend to have higher cash holdings. With this in mind, the precautionary motive view of CSR suggests that cash holdings serve as a hedge against trade credit risk, while, on the other hand, the substitution view of CSR predicts that cash hoarding discourages the provision of trade credit. Using a dataset of 20,591 firm-year observations from 1991 to 2015, we find strong evidence that supports both the trust and substitution views of CSR but not the precautionary view of CSR.     

On the reliability of unitizing textual continua: Further developments

This paper builds on an agreement coefficient proposed by Krippendorff (Content analysis: an introduction to its methodology, 2013) for measuring the reliability of unitizing and coding continuous phenomena, for example, of texts, videos, or sound recordings. It serves three purposes: It modifies Krippendorff’s definition which turned out to behave not as expected when applied to more than two observers, coders, or annotators. It extends this reliability measure to a family of four coefficients able to assess the reliabilities of diverse properties of unitized continua. It adds a way to obtain the confidence intervals of these coefficients as well as the probability of failing to reach targeted reliability levels. And it describes and provides access to free software that calculates all values of this family of reliability coefficients.     

Comparison of Cramer–Rao lower bounds of variances for at least equal protection of respondents

In this paper, a new randomized response model is proposed, which is shown to have a Cramer–Rao lower bound of variance that is lower than the Cramer–Rao lower bound of variance suggested by Singh and Sedory at equal protection or greater protection of respondents. A new measure of protection of respondents in the setup of the efficient use of two decks of cards, because of Odumade and Singh, is also suggested. The developed Cramer–Rao lower bounds of variances are compared under different situations through exact numerical illustrations. Survey data to estimate the proportion of students who have sometimes driven a vehicle after drinking alcohol and feeling over the legal limit are collected by using the proposed randomization device and then analyzed. The proposed randomized response technique is also compared with a black box technique within the same survey. A method to determine minimum sample size in randomized response sampling based on a small pilot survey is also given.     

The Clean Development Mechanism in a world carbon market

This paper discusses the role of the Clean Development Mechanism (CDM) in the market for carbon quotas and countries' commitments to reduce their carbon emission levels. We show that the CDM contributes to an efficient funding of clean technology investments in least developed countries. However, the CDM is not neutral on the global level of carbon emissions as it entices countries to raise their emission caps. The CDM may also make inappropriate the inclusion of any country that takes no emission abatement commitment. It can even make inefficient a country's decision to commit to an emission target. The implications of the presence of non‐additional projects are also analyzed.
