Return predictability in African stock markets

This paper models weekly index returns adjusted for thin trading as a nonlinear autoregressive process with conditional heteroscedasticity to investigate the weak-form pricing efficiency of 11 African stock markets. Specifically, the use of the EGARCH-M model allows us to capture how conditional volatility affects the pricing process without imposing undue restrictions on the parameters of the conditional variance equation. On the basis of such a robust model, we are able to reject the evidence in prior studies that the Nigerian stock market is weak-form efficient. On the other hand, we confirm extant results that the markets in Egypt, Kenya, and Zimbabwe are efficient while that of South Africa is not weak-form efficient. We also generate new results, which point to the efficiency of the stock markets in Mauritius and Morocco, while the markets in Botswana, Ghana, Ivory Coast, and Swaziland are not consistent with weak-form efficiency.     

What Makes a Blockbuster Video Game? An Empirical Analysis of US Sales Data

This study uses a unique data set of individual video game titles to estimate the effect of an exhaustive set of observable characteristics on the likelihood of a video game becoming a blockbuster title. Due to the long‐tailed distribution of the sales data, both ordinary least squares and logistic regression models are estimated. The results consistently show that blockbuster video games are more likely to be released by one of the major publishers for popular hardware platforms. Results also show that games of higher quality are significantly more likely to sell a greater number of units than those of a lower quality. Copyright © 2013 John Wiley & Sons, Ltd.     

Hedging dairy production losses using weather-based index insurance

This article proposes a temperature–humidity index insurance product and examines whether this product can effectively protect against the risk of reduced milk production caused by heat stress. Results suggest that even when premiums are at higher than actuarially fair levels and the insurance purchaser is faced with both spatial and temporal basis risks, a temperature–humidity index insurance product would provide risk management benefits to a representative south‐central Georgia dairy producer.     

Cause‐related marketing and customer donations in an online marketplace

• eBay for Charity provides mechanisms for embedding charitable fundraising and donations into the UK's largest online marketplace, with 18 million unique visitors each month. This paper explores some of our findings concerning the impact of charitable activity on the behaviour of those who participate, including buyers, sellers, and the charities themselves, and suggests ways these findings could be applied to other forms of online fundraising in the future.

Modeling Job Pursuit Intention: Moderating Mechanisms of Socio-Environmental Consciousness

Many scholars have suggested the relationship between corporate social performance and its ability to attract a large number of high-quality job applicants, because previous literature indicates that employees with strong social awareness help create a high-performance organization. For that reason, an important issue for successful business recruitment is how to boost the pursuit intention of job seekers. This study discusses such issue by proposing a model based on signaling theory and cognitive dissonance theory. In the proposed model of this study, the positive relationships between four dimensions of corporate social performance and job pursuit intention are hypothetically moderated by socio-environmental consciousness. The proposed hypotheses of this research were empirically tested using the data from graduating students seeking a job. The empirical findings of this study complement previous literature by discussing how corporate social performance benefits business firms from a perspective of strengthened human resources and recruitment. Finally, managerial implications for business managers based on the findings herein are provided.     

Strategic human resource management and inertia in the corporate entrepreneurship of a multinational enterprise

Abstract

Corporate entrepreneurship (CE) supports sustained competitive advantage through the continuous exploration and exploitation of new sources of knowledge. With an emphasis on combining knowledge in new configurations, strategic human resource management (HRM) activities are core to these entrepreneurial endeavours. We explore how strategic HRM activities may facilitate and impede CE through a rich, qualitative case study of three local entities within a business unit of a large multinational enterprise facing business stagnation and low levels of corporate entrepreneurship. Responding to a call for more empirical research that probes the subtle and complex interactions between HRM activities and other organisational factors affecting CE, we identify a configuration of inter-dependent factors that mutually reinforce each other and sustain inertia in corporate entrepreneurship. We also make two novel contributions to theory by (1) elaborating the links between organisational process-orientation, strategic HRM and CE; and (2) refining to our current understanding of human competencies for CE.     

To Share or Not to Share: Assessing Knowledge Sharing, Interemployee Helping, and Their Antecedents Among Online Knowledge Workers

Sharing and helping are important issues in ethical research. This study proposes a model based on flow theory by postulating key antecedents as the critical drivers of knowledge sharing and interemployee helping. Flow is the holistic sensation that employees feel when they act with total immersion and engagement, facilitating individuals’ reciprocal activities such as knowledge sharing and interemployee helping. In the proposed model, knowledge sharing is influenced by flow experience directly and also indirectly via the mediation of interemployee helping. Accordingly, the flow experience is influenced simultaneously by four exogenous factors related to individuals’ perception about their work: work skills, self-fulfillment in challenges, perceived control, and vividness. This study contributes to the knowledge management literature by extending flow theory to the area of knowledge sharing and interemployee helping, by validating idiosyncratic antecedent drivers of the flow theory, and by performing a practical operationalization of the flow experience. This research also provides managerial implications for business leaders to boost their employees’ ethical behavior in terms of sharing and helping.
