International mergers and acquisitions: A jump diffusion model application

This paper empirically investigates international mergers and acquisitions (M&As) of foreign targets and bidders by analyzing the stock price behavior of the firms involved. The jump diffusion model is employed to study the effects of the M&A announcements on stock prices. The results indicate that acquisition announcements are perceived as a surprise by the market, but prices seem to adjust rather rapidly, supporting the semi-strong form of the market efficiency hypothesis. In addition, a comparison of the pure diffusion and jump diffusion models indicates that the jump diffusion model is statistically superior to the traditional event study methodology (pure diffusion model).

International briefing 7: Training and development in Singapore

Singapore’s only resource is its people. It has made HRD as a key strategy for economic development since its inception. Its economic success story is entwined with the training and development of its workforce. A national manpower development infrastructure has been put in place to facilitate training and lifelong learning of its people for the twenty‐first century under a master plan called Manpower 21. Continuous training and skills development has been possible through close cooperation between the state, employers and the unions through unique working relationships between several policy‐making institutions, such as the National Manpower Council and the National Wages Council.     

The 1994–1995 Mexican Currency Crisis and U.S. Bank Stock Returns

We investigate the impact of the 1994–1995 Mexican currency crisis on U.S. bank stock returns. We use a jump-diffusion model rather than a pure diffusion model to describe daily stock returns, because the public release of unexpected information generally is associated with discrete jumps in prices. Traditional event study models pool both announcement effects and trading effects and may lead to inefficient estimators. The jump-diffusion model can separate the impact of informed trading from unanticipated public announcements. Our results indicate that the variance of the jumps is large and increases with bank size and portion of loans to Mexico.     

Learning lessons: how to practice nudging around the world

Abstract

The aim of this article is to cover three things: (1) to introduce the context behind why a report prepared by the Organisation for Economic Co-operation and Development (OECD) in 2017 would be of such importance to researchers in various academic disciplines and public policy, (2) to present the details of a simple classification system that was applied to all 111 case studies of behavioural interventions (better known as nudges) referred to in the OECD (2017a OECD. 2017a. Behavioural Insights and Public Policy Lessons from Around the World.1-408 pp. OeCD Publishing. https://read.oecd-ilibrary.org/governance/behavioural-insights-and-public-policy_9789264270480-en. doi:10.1787/9789264270480-en.[Crossref] , [Google Scholar]) report, and (3) to discuss what needs to be done to help advance practitioners’ pursuit of effective behavioural interventions. This article aims to highlight the importance of accurately cataloguing the types of behavioural interventions that have been trialled/implemented across the world. By adopting an agreed classification system, researchers and practitioners can benefit from knowing what can work, and where it can work, as well as what does not work, in order to be better armed when considering the use of behavioural interventions to solve social policy issues.     

Stressors,work engagement and their effects on hotel employee outcomes

Our study aims to revisit the challenge-hindrance stressor framework among customer-contact employees. Specifically, our study links challenge and hindrance stressors to four critical employee outcomes via work engagement (WE). These outcomes are quitting intentions, service recovery performance, creative performance, and job performance. Data came from hotel employees in customer-contact positions in three waves and their direct supervisors in Nigeria. As hypothesised, WE fosters service recovery, creative, and job performances, while it mitigates quitting intentions. Inconsistent with our predictions, hindrance stressors boost WE and challenge stressors exert detrimental effects on WE. Although WE links challenge and hindrance stressors to the aforementioned outcomes, the signs of the mediating effects are not congruent with what is hypothesised in the study. These unexpected findings agree with Bakker and Sanz-Vergel’s [2013] proposition that categorisation of job demands as challenge or hindrance stressors may not always be straightforward.     

Affectivity and organizational politics as antecedents of burnout among frontline hotel employees

This study investigates perceptions of organizational politics as a mediator of the effects of negative affectivity and positive affectivity on burnout. Based on data obtained from frontline hotel employees in Turkey, results reveal that the impacts of negative affectivity on exhaustion and disengagement, through perceptions of organizational politics, are stronger than positive affectivity.     

Can Loan Valuation Adjustment (LVA) approach immunize collateralized debt from defaults?

This study focuses on structuring tangible asset backed loans to inhibit their endemic option to default. We adapt the pragmatic approach of a margin loan in the configuring of collateralized debt to yield a quasi‐default‐free facility. We link our practical method to the current Basel III (2017) regulatory framework. Our new concept of the Loan Valuation Adjustment (LVA) and novel method to minimize the LVA converts the risky loan into a quasi risk‐free loan and achieves value maximization for the lending financial institution. As a result, entrepreneurial activities are promoted and economic growth invigorated. Information asymmetry, costly bailouts and resulting financial fragility are reduced while depositors are endowed with a safety net equivalent to deposit insurance but without the associated moral hazard between risk‐averse lenders and borrowers.     

The effect of job resourcefulness on role stress,emotional exhaustion and overall performance: A study of frontline bank employees

This article develops and tests a conceptual model that examines the effects of co-worker support and job resourcefulness on role stress, emotional exhaustion and job performance. The data obtained from frontline bank employees with a time lag of two weeks in Northern Cyprus were used to test these relationships. The results of structural equation modelling suggest that the partially mediated model seems to have a better fit than the fully mediated model. The results further suggest that job resourcefulness partially mediates the effect of co-worker support on role ambiguity and emotional exhaustion. However, there is no empirical support for job resourcefulness as a mediator of the impact of co-worker support on role conflict and job performance. The implications of the results are discussed and their future research directions are offered.     

The extent of marketability and consumer preferences for traditional leafy vegetables – a case study at selected markets in Ghana

This paper reports on a survey conducted at two major marketing centres in Ghana; Tamale in the dry savannah zone and Kumasi in the forest zone. One hundred traders were interviewed using a semi‐structured questionnaire and focus groups discussions held on traders’ perceptions and consumer preferences, relative importance and indigenous nutritional knowledge of traditional leafy vegetables (TLVs). The survey established that, with the exception of Xanthosoma mafafa (cocoyam leaves), inter‐market distribution of TLVs is limited because of their perishable nature, narrow utilization base and lack of storage techniques. Socio‐culturally related factors limiting the distribution of TLVs include regional diversity and ethnic differences in the dietary patterns of the Ghanaian populace, inadequate knowledge about the methods of preparations as well as nutritional and medicinal values of TLVs. The most preferred TLVs as reflected in the consumers’ buying behaviour and traders’ perceptions are Xanthosoma mafafa (cocoyam leaves), Corchorus spp.(Ayoyo), Amaranthus spp (Alefu) and Hibicus sabdariffa (Bra). The order of preference in the forest zone is Xanthosoma mafafa (cocoyam leaves) > Corchorus spp.(Ayoyo) > Amaranthus spp (Alefu) > Hibicus sabdariffa (Bra), while the reverse order pertains in the savannah zone.
