Food‐aid dependency in Lesotho: Issues and policy implications

This article analyses food‐aid dependency in Lesotho and how it can be reduced. The study uses primary data on food aid, statistics collected from various food‐aid agencies and institutions, and secondary data obtained from government sources. Food‐aid de pendency is likely to continue in the long term, as food aid enhances food security in Le sotho by supplementing commercial imports to meet the shortfall in local cereal produc tion. Food aid improves the nutritional and consumption levels of vulnerable Lesotho households but shows no correlation with producer and consumer prices. If the level of food‐aid dependence is to be reduced, measures to alleviate poverty and generate income must be implemented.     

A model of a rural household in KwaZulu

This paper reports an attempt to model household economic behaviour on a small farm in KwaZulu using mathematical programming techniques. To some extent the effects of risk, leisure and off‐farm employment opportunities on resource allocation and farm output are captured in the model Different decision rules including versions of the Wald maximin criterion (Maximin), the Savage regret criterion (Minmax), Motad and maximisation of a ‘sumex’ utility function were used in the optimisation process. Predicted and observed enterprise levels are compared and the paper concludes with comment on the model and problems involving specification of income, leisure and consumption relationships in the programming approach.     

When and why? A critical survey on coordination failure in the laboratory

Coordination games with Pareto-ranked equilibria have attracted major attention over the past two decades. Two early path-breaking sets of experimental studies were widely interpreted as suggesting that coordination failure is a common phenomenon in the laboratory. We identify the major determinants that seem to affect the incidence, and/or emergence, of coordination failure in the lab and review critically the existing experimental studies on coordination games with Pareto-ranked equilibria since that early evidence emerged. We conclude that there are many ways to engineer coordination successes.      

The link between the Shapley value and the beta factor

In this article, we provide a link between the Shapley value in cooperative game theory and the capital asset pricing model (CAPM) in finance. In particular, the Shapley value of a suitably defined cooperative game is closely related to the beta factor in the CAPM. The beta factor for any given security may be interpreted as the asset’s fairly allocated share of the market risk or as the asset’s average marginal contribution to the market risk, respectively. Other fairness properties and axioms of the Shapley value may be reinterpreted in this context to attain a deeper understanding of the beta factor and the connotation of systematic risk. Our game theoretic approach further allows for a generalisation of the CAPM with respect to arbitrary risk measures other than variance. Last but not least, we discuss the volatility of an asset’s theoretical fair assessment of risk and of its systematic risk, respectively. This result lends itself to face the challenge of an empirical investigation on real stock markets.     

Business Cultural Intelligence Quotient: A Five‐Country Study

Cultural intelligence (CI) has often been linked to performance at the individual, team, and firm levels as a key factor in international business success. Using a new measure of CI, the business cultural intelligence quotient (BCIQ), our study provides empirical evidence on several key antecedents of CI using data on business professionals across five diverse countries (Austria, Colombia, Greece, Spain, and the United States). The findings suggest that the most important factors leading to cultural intelligence, in order of importance, are the number of countries that business practitioners have lived in for more than six months, their level of education, and the number of languages spoken. We find that cultural intelligence varies across countries, suggesting that some countries have a higher propensity for cross‐cultural business interactions. By teasing out the common antecedents of BCIQ among professionals, our findings may help with screening and training professionals for international assignments. Future research may examine the environmental (country‐specific) factors associated with a higher propensity for cultural intelligence (such as immigration, cultural diversity, languages spoken, and international trade) to explain the effect of country of origin on cultural intelligence in the professional community. © 2016 Wiley Periodicals, Inc.     

Engagement with Retirement Savings: It Is a Matter of Trust

People who engage with their retirement savings are more likely to opt out of unsuitable defaults. We use cluster analysis of matched survey and administrative data to identify groups of pension plan members that are alike in their attitudes toward retirement saving. We find that engaged and disengaged members segregate into groups based on their interest and trust. Group membership in turn helps predict plan engagement, as proxied by nondefault choices. Specifically, engagement is stronger among interested groups. Trust, however, has a more complex relationship with engagement, particularly as it interacts with interest. While members with low interest and high trust are less likely to engage (e.g., by not checking plan performance), less trusting members engage more (e.g., by actively choosing asset allocations). As interest and trust successfully determine group membership, and ultimately engagement, pension plan providers should address members' diverse needs and circumstances with personalized approaches.     

Life Satisfaction,Income Comparisons and Individual Traits

People gain utility from occupying a higher ranked position in the income distribution of the reference group. This paper investigates whether these gains depend on an individual's set of personality and affective traits. Using the 2000 to 2013 waves of the German Socio‐economic Panel dataset (SOEP), a subjective question on Life Satisfaction, and three different measures of personal and affective traits, we find significant and robust differences across groups and conclude that traits determine the relationship between rank and life satisfaction. The heterogeneity on the importance of income comparisons is relevant, for example, when building economic models, predicting individuals' behavior, or making welfare judgments.     

Stromspeicher im Quartier

Electricity storage is a possible flexibility option to increase the share of fluctuating electricity sources from renewable energies in the electricity system. In the past, most attention was paid to household and large storage facilities. Community storage solutions at the meso level have so far been largely neglected. It is only in the context of the change in legislation for the electricity supply of tenants that neighborhood solutions have recently been increasingly discussed.In essence, this article examines the challenges currently arising in the context of the implementation of electricity storage facilities at community level in Germany. To this end, the term “community storage” is first being discussed and outlined. Subsequently, economic-legal and socio-cultural challenges are presented and discussed as central challenges in the implementation of neighborhood storage solutions in Germany. Based on the discussion of current challenges, possible business models for the implementation and operation of district storage facilities in Germany will then be derived.
