Managing basis risk with multiscale index insurance

Agricultural index insurance indemnifies a farmer against losses based on an index that is correlated with, but not identical to, her or his individual outcomes. In practice, the level of correlation may be modest, exposing insured farmers to residual, basis risk. In this article, we study the impact of basis risk on the demand for index insurance under risk and compound risk aversion. We simulate the impact of basis risk on the demand for index insurance by Malian cotton farmers using data from field experiments that reveal the distributions of risk and compound risk aversion. The analysis shows that compound risk aversion depresses demand for a conventional index insurance contract some 13 percentage points below what would be predicted based on risk aversion alone. We then analyze an innovative multiscale index insurance contract that reduces basis risk relative to conventional, single‐scale index insurance contract. Simulations indicate that demand for this multiscale contract would be some 40% higher than the demand for an equivalently priced conventional contract in the population of Malian cotton farmers. Finally, we report and discuss the actual uptake of a multiscale contract introduced in Mali.     

Comparative study of cognitive styles in Egypt,Greece, Hong Kong and the UK

Cognitive style has been described as consistent individual differences in the organising and processing of information. It is has been argued that it is an important factor in managerial learning and cognition. A number of authors have suggested that groups from different national cultures are likely to exhibit style differences and that this has important implications for management training and development. In the present study, which employed closely matched samples of business and management undergraduates from Egypt, Greece and the UK, there were no statistically significant differences in style. However, in post‐graduate samples from Egypt, Hong Kong and the UK that were less closely matched, statistically significant differences were observed. Comparison of these data with those from other studies suggests that amongst under‐graduates from a variety of national cultures there do not appear to be significant differences in style. Among post‐graduates and managers the picture that emerges was more equivocal and the extent to which any observed differences are artefacts of sampling and method remains unclear. The implications of the findings for style theory and management education, training and development are discussed.     

Factors affecting undergraduates' commitment to career choice in the hospitality sector: Evidence from Saudi Arabia

Little is known about the factors underlying students’ commitment to career choices in the hospitality industry in non-western contexts. This research explores the drivers of commitment to career choice among undergraduates studying hospitality in Saudi Arabia. Employing the Social Cognitive Career Theory, this research examines commitment to hospitality career against personal and contextual variables, together with two control variables of (i.e., “year of study” and “industry experience”), expected to influence students’ career decisions. From a valid sample of 227 students, it was found that “self-interest,” “outcome expectations,” “the nature of working environment,” “the nature of working day,” “nepotism (wasta),” “industry experience,” and “year of study” were the best predictors of students’ commitment to career choice; in contrary, “social status” and localization (saudization) of workforce were not significant determinants. Implications of the findings and avenues for future research are also discussed.     

Return predictability: The dual signaling hypothesis of stock splits

This paper aims to differentiate between optimistic splits and overoptimistic/opportunistic splits. Although markets do not distinguish between these two groups at the split announcement time, optimistic (overoptimistic/opportunistic) splits precede positive (negative) long‐term buy‐and‐hold abnormal returns. Using the calendar month portfolio approach, we show that the zero‐investment, ex ante identifiable, and fully implementable trading strategy proposed in this paper can generate economically and statistically significant positive abnormal returns. Our findings indicate that pre‐split earnings management and how it relates to managers’ incentives, is an omitted variable in the studies of post‐split long‐term abnormal returns.     

A framework for analyzing flexibility of generic objects

Flexibility is a loosely defined term used in a number of application areas with different and frequently contradicting views. In this paper, adopting as a starting point the use of the term in the manufacturing and information systems domains, we present a framework for the examination of generic objects utilizing cloud diagrams. We first portray the potential flexibility of a designed object and then its actual flexibility expressing its ability to adapt to changes. Examples of its use illustrate the ideas and their application. We believe that this research will be helpful in offering guidelines to designers of new systems where flexibility is important.     

Migrants’ Remittances and Financial Development: Macro‐ and Micro‐Level Evidence of a Perverse Relationship

Financial development is commonly identified as an important condition for fostering investment and economic growth. It is also believed that migrants’ remittances stimulate financial development in the receiving economy, contributing indirectly to economic growth. We explore the relationship between remittances and financial development using macro‐ and micro‐level data. From cross‐country panel data, we find evidence of a negative relationship between remittances and financial deepening in developing countries. Using household survey data from a study of migrants’ remittances in two CIS countries, Azerbaijan and Kyrgyzstan, we also investigate the relationship between remittances, financial intermediation and ‘financial literacy’ among remittance‐receiving households. While we find some evidence of a positive, albeit weak, relationship for Kyrgyzstan, in Azerbaijan, the relatively more financially developed economy, we uncover a strong perverse relationship. Remittances appear to deter bank intermediation and use of formal banking services. Possible reasons are explored and areas for further investigation identified.
