Information disclosure quality: correlation versus precision

We investigate how a multidimensional disclosure quality (i.e., correlation and precision) determines an optimal information disclosure strategy. We find that, for an infinitely lived, unlevered firm with market perfection, a truth‐telling disclosure is optimal at increasing the expected firm value. However, for a finitely lived, levered firm in the presence of market imperfections (e.g., bankruptcy cost), the optimal disclosure quality depends negatively on the level of imperfections. Once we consider the agency problem, such dependence can become positive, thereby highlighting the importance of a proper managerial‐incentive scheme to align the information disclosure interests of managers and shareholders.     

Trading timing and the returns to trend-following

We document a negative impact of realistic trading timing on trend-following profits, across an international sample of equity indexes and stocks. The discount effect is substantial but reduces as trend signals become less accurate. The size of this trading timing bias is largely driven by the volatility of buy-and-hold returns and that of trend signals.     

Does increased hedging lead to decreased price efficiency? The case of VIX ETPs and VIX futures

We examine the impact of the introduction of VIX exchange‐traded products (ETPs) on the information content and pricing efficiency of VIX futures. We document that trades in VIX futures have become less informative and that pricing errors exhibit more persistence after the introduction of VIX ETPs. In addition, we observe that the price process of the VIX futures has become noisier over time. These findings suggest that the introduction of the VIX ETPs had a prominent effect on the properties and dynamics of the VIX futures.     

Alternative balanced scorecards built from paradigm models in strategic HRM and employment/industrial relations and used to measure the state of employment relations and HR system performance across U.S. workplaces

This paper constructs alternative balanced scorecards based on high‐performance work system (HPWS) and employment relations system (ERS) models. The models are depicted and compared in diagrams and used as framework skeletons for building separate HPWS and ERS scorecards, intended to provide a detailed data picture of the operational health and performance of an organization's employment/HR system and its operations, processes, and inputs/outputs. The scorecards are filled in with nationally representative data from 2,000+ U.S. workplaces using more than 50 employment/HR indicators, as reported by separate panels of managers and employees. The indicators for each workplace are aggregated into an overall HR/employment system score, ranked from low‐to‐high, and graphed as frequency distributions. These distributions provide a unique snapshot picture of the mean and dispersion of the state of employment relations and HR system performance for companies across the United State. They also reveal that “models matter” since the HPWS and ERS scorecards provide distinctly different evaluation assessments.     

Online customer experience in e-retailing: implications for web entrepreneurship

Providing consumers with unique experiences and immersing them in original contexts are the goals of web entrepreneurs. Researchers and web entrepreneurs have expressed a particular interest in the online customer experience, agreeing on its importance in creating satisfaction, revisiting intention, e-trust and e-loyalty. This paper explores customer experience in the online retail context. The online customer experience is central in forming customers’ perceptions of expectations of online retailers because this experience is highly personal. However, empirical research on the online customer experience remains scarce. The objectives of this unique study are twofold. The first is to compare the effect of online customer experience on the responses of Romanian and Tunisian customers. The comparative analysis is based on two dimensions of the online customer experience assessment tool. These dimensions are cognitive experiential state (flow) and affective experiential state. The second objective is to examine the contribution of each of these two dimensions in explaining overall perceived value, e-satisfaction, e-trust and repurchase intention in the online context, as well as their effects on web entrepreneurial initiatives. The findings reveal the impact of cultural influences on the constructs embedded in the research framework. The implications for practice relate to the increasing importance of online customer experience in tailoring online marketing campaigns. The implications for web entrepreneurship are clearly emphasised by the pathways from online customer experience to entrepreneurial initiatives. These pathways capture the value of customer-generated content in designing innovative business models.

     

The magic of the new: How job changes affect job satisfaction

We investigate a crucial event for job satisfaction: changing one's workplace. For representative German panel data, we show that the reason why the previous employment ended is strongly linked to satisfaction with the new job. Workers initiating a change of employer experience extraordinarily high job satisfaction, though in the short term only. To investigate causality, we exploit the event of plant closure as an exogenous trigger of job switching. In this case, we find no significantly positive effect of job changes on job satisfaction. Our findings complement research on workers’ well‐being and concern labor market policies and human resource management.     

Work motivation and public service motivation: disentangling varieties of motivation and job satisfaction

Research on motivation in the public sector has used public service motivation (PSM) and self-determination theory (SDT) interchangeably. This paper compares both theories, develops hypotheses pertaining to their assumptions, and empirically tests them in two public offices in Switzerland. We then explore their relationship with job satisfaction as an indicator of predictive validity. We find that SDT and PSM display conceptual differentiation and SDT has a strongest relationship to job satisfaction. However, moderation analysis suggests that employees with high levels of PSM have more stable job satisfaction compared to their low-PSM counterparts.     

The role of peer-to-peer voice in severe work environments: organisational facilitators and barriers

Encouraging and facilitating employee voice among frontline employees is important in organisations to draw out problems and issues that can potentially be addressed and mitigated by organisational policies and practices. Using Conservation of Resources theory, this study focuses on paramedics and the formal and informal voice mechanisms used to safeguard their well-being. We observe that paramedics are often unwilling to use formal support mechanisms, at least in the first instance immediately following exposure to a traumatic event, but they see informal peer-to-peer voice as critical in preventing resource loss and regaining resources for subsequent call-outs. We also found that without an awareness of the importance of this support mechanism, changes in work organisation can unintentionally and unknowingly limit their capacity to engage in this form of support. Losing peer-to-peer voice can lead to the build-up of stress that could otherwise be mitigated, resulting in diminished well-being.     

Biofuels technology development in Southern Africa

ABSTRACT

The benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, will reduce both the costs of biofuels production, and the environmental impacts. Compared to petroleum fuels, the current commercial biofuels (ethanol, biogas and biodiesel) typically offer carbon emission reductions of 30–50% but are marginally more expensive. The extent of biofuels market penetration will therefore be influenced by mandates (blending targets) and subsidies (green premium). Advanced biofuels promise greater efficiencies and carbon emission reductions at reduced cost but will require further research and development to reach commercialisation. If developed appropriately, biofuels can reduce carbon emissions and improve energy security, while enabling sustainable agriculture and improved natural resources management.
