Condorcet Jury Theorem: An example in which informative voting is rational but leads to inefficient information aggregation

Recent research on the Condorcet Jury Theorem has proven that informative voting (that is, voting according to one’s signal) is not necessarily rational. With two alternatives, rational voting typically leads to the election of the correct alternative, in spite of the fact that not all voters vote informatively. We prove that with three alternatives, there are cases in which informative voting is rational and yet leads to the election of a wrong alternative.     

Novel indicators of the trade and welfare effects of agricultural distortions in OECD countries

Agricultural markets in OECD countries have long been highly distorted by government policies. Traditional weighted average aggregates of the price distortions involved, such as producer and consumer support estimates (PSEs and CSEs), can be poor indicators of the trade restrictiveness and economic welfare losses associated with them, especially if a country’s support estimates vary a lot across the product range. Certainly estimates of trade and welfare effects of price supports can be obtained from sectoral or economywide models using price elasticity estimates, but the results can be contentious if there is no consensus on what model specification and elasticity parameters to use. This paper shows that, if there is a willingness to accept simple assumptions about elasticities, it is possible to generate indicators of the welfare and trade restrictiveness of agricultural policies using no more than the price and quantity data needed to generate PSEs and CSEs. These new indexes thus provide an attractive supplement to the current policy monitoring regime developed by the OECD Secretariat.     

Information seeking by female apparel consumers in South Africa during the fashion decision‐making process

Fashion information is sought during the fashion decision‐making process and can be obtained from various sources such as magazines, fashion consultants, websites and store displays. Various levels and methods such as internal and external search for information are used to assist the consumer in making informed fashion decisions. The broad research aim of this study was to determine which methods, sources and economics of fashion information are sought and used by female educators in Vanderbijlpark (South Africa) during the fashion decision‐making process, and to which extent. A self‐administered, structured questionnaire was used to collect the data. Section A measured methods of information seeking, section B determined the economics of information search and section C investigated sources of fashion information. Demographic information was investigated in Section D. A random cluster sample of eight schools was chosen from the female educating staff of 22 schools. The biggest group of the educators (40.18%) was between the ages of 41 and 50, which according to a South African categorization represents baby boomers. Almost all (95.5%) had a higher education qualification obtained at a university and most (82.14%) were married. Regarding the methods of information seeking, the respondents depended on internal information seeking more than on external methods and were moderately involved in the process. Shopping in stores was regarded the most important source of fashion information. Cluster analysis revealed that four clusters of respondents could be distinguished, each with a specific disposition towards the methods and economics of search as well as sources used during the fashion decision‐making process.     

Income inequality between Chinese regions: newfound harmony or continued discord?

This paper develops an improved test of economic convergence or divergence using time series methods by introducing nonlinear trends in the form of logarithmic trend functions into the vector error correction model. The usefulness of the method is illustrated in an analysis of the growth pattern between Chinese regions in 1952–2007. Comparing all combinations of regional pairs, the analysis yields support for economic divergence in roughly half of the cases. In the other half, we instead find that regions have grown while maintaining stable income differences. As such, the results show the co-existence of divergence and conditional convergence among China’s regions.     

Inhabited Actors: Internalizing Institutions through Communication and Actorhood Models

We argue that accounts of relationships among actors, actorhood and institutions are predominantly based on a spatial metaphor of actors operating within institutions. We outline how an inversion of this metaphor – i.e., the perspective that institutions inhabit actors – may prove generative for theory, particularly with respect to recent discussions about the microfoundations of institutions. We outline how communication and actorhood models function as transmission mechanisms of institutions from one actor to another. We conclude with a discussion of how the inverted metaphor of institutions inhabiting actors can be useful for future theoretical developments.     

Context and mobile services' value-in-use

Context is an inherent part of service use experiences that helps to understand when mobile services generate superior value-in-use for customers and are preferred to other services, but little research exists on the subject. In order to fill this void, a theoretical value framework incorporating context is proposed. The findings of 85 mobile service use situations indicate strong evidence for two types of value: context value and value-in-use. Furthermore, the paper identifies new context value categories such as uncertain conditions, refines the meanings of other context and value-in-use categories, and concludes that conditional value enhances the value of mobile services.     

The Corporate Ethical Virtues Scale: Factorial Invariance Across Organizational Samples

This study investigated the factorial validity of the 58-item Corporate Ethical Virtues scale (CEV; Kaptein, J Organ Behav 29(7):923–947, 2008). The major aim was to test the invariance of the factor structure across different organizational samples. The CEV scale was designed to measure eight corporate virtues: clarity, congruency of supervisors, congruency of senior management, feasibility, supportability, transparency, discussability, and sanctionability. The data (total N = 3,702) consisted of four organizational samples that are operated in the private and public sector. The results of confirmatory factor analyses supported the hypothesized eight-factor structure, as well as its alternative second-order factor structure, where high correlations between the first-order factors (virtues) were explained by a general CEV factor. These factor structures (including factor loadings) remained the same across samples, lending strong support for the group invariance assumption of the scale. Thus, the 58-item CEV scale was found to be a valid tool for measuring the aspect of ethical organizational culture in different organizations, and its use can be recommended for future research.     

The Influence of Internal Communities of Practice on Customer Perceived Value in Professional Service Relationships

Effective customer-related knowledge transfer can be seen as the cornerstone of customer value creation in collaborative relationships between professional service organisations and their customers. Our intention in this paper is to describe how different work groups within organisations (communities of practice) influence the perceived customer value. We approach this phenomenon from a relationship management perspective and use literature from relationship marketing, organisation research and knowledge management as a theoretical basis. Empirically the paper is based on an information-rich explorative case study of a professional service organisation, operating in the consultancy and training business, and its relationship with one of its customers.     

Workplace problems,mental health and substance use

Little is known about how workplace problems may influence diagnosable mental health and substance use (MHSU) disorders. We examine the associations between three common workplace problems (experiencing problems with co-workers, job changes and perceived financial strain) and three MHSU disorders (mood, anxiety and substance abuse/dependence). The analysis utilizes longitudinal data on a sample of working-age adults from the National Epidemiological Survey on Alcohol and Related Conditions. These data are well suited for our research objective as the survey was specifically designed to study MHSU disorders. Results show that experiencing these workplace problems is associated with an increased risk for mental health disorders, but not substance use disorders. Importantly, various robustness checks and sensitivity analyses demonstrate that our findings cannot be not fully explained by omitted variables, reverse causality or sample attrition.
