Knowledge sharing,knowledge leaking and relative innovation performance: An empirical study

External knowledge sharing and knowledge leakage often pose a strategic dilemma when firms conduct innovation activities. In this study, we focus on the positive and negative effects of this phenomenon. In particular, we empirically examine the effects of a firm׳s external knowledge sharing on its relative innovation performance under the contingencies of accidental and intentional leakage of business-critical knowledge. Results based on a survey of 150 Finnish technology-intensive firms show that external knowledge sharing has a positive effect on innovation performance, but high levels of accidental and intentional knowledge leakage by a firm׳s employees negatively moderate this relationship. These results contribute to the understanding of the potentially positive and negative issues related to external knowledge sharing and knowledge leakage, which have thus far remained empirically under-researched.     

Managing security risks for inter-organisational information systems: a multiagent collaborative model

Information sharing across organisations is critical to effectively managing the security risks of inter-organisational information systems. Nevertheless, few previous studies on information systems security have focused on inter-organisational information sharing, and none have studied the sharing of inferred beliefs versus factual observations. In this article, a multiagent collaborative model (MACM) is proposed as a practical solution to assess the risk level of each allied organisation’s information system and support proactive security treatment by sharing beliefs on event probabilities as well as factual observations. In MACM, for each allied organisation’s information system, we design four types of agents: inspection agent, analysis agent, control agent, and communication agent. By sharing soft findings (beliefs) in addition to hard findings (factual observations) among the organisations, each organisation’s analysis agent is capable of dynamically predicting its security risk level using a Bayesian network. A real-world implementation illustrates how our model can be used to manage security risks in distributed information systems and that sharing soft findings leads to lower expected loss from security risks.     

Stock liquidity and managerial short-termism

We examine whether stock liquidity exacerbates or mitigates managerial short-termism. Utilizing earnings management as a proxy for managerial short-termism, we establish three major findings. First, firms with liquid stocks engage in less accrual-based and real earnings management. Second, the effect of stock liquidity on earnings management is amplified for firms with high levels of managerial pay-for-performance sensitivity. Third, the positive association between the intensity of earnings management and firm cost of capital is evident only for firms with low stock liquidity. Our findings are consistent with the threat of blockholder exit as the main governance channel through which stock liquidity discourages opportunistic earnings management and mitigates managerial short-termism.

法制环境、管理者能力与企业债务契约

本文从管理者能力的视角出发,选取2010-2018年沪、深A股上市公司为样本,实证分析了管理者能力对债务契约的影响及其影响路径。研究证明:管理者能力越强,企业的债务期限结构越短、债务融资成本越低。进一步研究发现,在不同的法制环境中,二者的关系存在异质性,即管理者能力对债务期限结构、债务融资成本的影响在法制环境较高的地区较为显著。本文丰富了企业债务契约的影响因素,探寻了管理者能力影响债务期限结构、债务融资成本的路径。     

Knowledge sharing in the hospitality context: The roles of leader humility,job crafting,and promotion focus

Grounded in a view of self-transcendence, leader humility is expected to influence employees to acquire and share knowledge for self-development. This study investigates how and when leader humility activates hospitality employees’ knowledge collection and knowledge donation. The dataset was built from 674 employees and 87 direct managers working in the Vietnam-based hotel organizations. Analyzed through multilevel structural equation approach, the data provided support for the positive relationships between leader humility and knowledge collection and donation behaviors among hospitality employees. The three dimensions of job crafting functioned as mediators for these relationships. Employees’ promotion focus played a moderating role for the relationships between leader humility and seeking resources and challenges, but did not interact with leader humility to impact job demands. The discussion on the implications for hospitality scholars and practitioners from the research findings is presented.     

基于角色视角的分享经济信任机制研究

基于信任理论，从不同角色视角探究各信任要素对分享经济行为意图的影响。通过构建分享经济信任机制概念模型以及实证检验发现：从需求方视角来看，对个体（供给方）3个维度（能力、正直和善意）的信任、对平台善意的信任以及对产品能力的信任对需求意图产生积极地影响。从供给方视角来看，对个体（需求方）能力的信任和对平台3个维度（能力、正直和善意）的信任对供给意图有正向的影响。需求方更关注人与人之间的信任，而供给方则更看重对平台的信任。通过进一步比较还发现，需求方对平台和个体（供给方）的信任聚焦于善意信任，但供给方则是侧重于对平台和个体（需求方）能力的信任。

Product price and performance level in one market or two separated markets under various cost structures and functions

Market characteristics, including intrinsic demand and customer sensitivity on price and product performance level, are distinct at different markets. Comparisons of various product development strategies in one market or two geographically separated markets are conducted for three classes of products: development intensive products (DIPs) with constant unit cost, marginal cost-intensive products (MIPs) with constant fixed cost, and marginal and development intensive products (MDIPs) with non-constant unit cost and fixed cost. Results show that larger demand size, less customer sensitivity on price and/or more sensitivity on performance level lead to more profit, a higher sale price and a not-lower product performance. The customer reservation or the saturation performance level should be generally adopted though the optimal performance level does exist occasionally. Unit cost and/or fixed cost must increase in performance at an increasing rate for the existence of one optimal performance level. Due to the impact of demand size, one high-end (low-end) MDIP or DIP could be introduced into one low-end (high-end) market at a different price if the demand size is significantly large in the low-end market. For DIPs, offering one niche high-end product is not worse than offering the low-end product into two markets. For MIPs with negligible fixed cost, the product line strategy is not worse than the standard product development strategy. Additionally, the product cost reduction approach adopted in one product line has significant effects on the best product development strategy and sequence.     

The going public decision and the structure of equity markets

The industries in which listed firms are concentrated in less developed equity markets are not random, nor entirely explained by the underlying composition of production. Listed firms and market capitalization are disproportionately concentrated in industries with low beta (measured with their beta with the market portfolio in the U.S.). We document a strong positive relationship between the industry-weighted country beta and the degree of market development across countries. Recent IPO activity confirms the result since new listings have higher betas than the average firm already in the market.
