This paper describes a search model with a continuum of worker and job types, free entry and transferable utility. We apply a second-order Taylor expansion to characterize the equilibrium, derive the "cost of search" and show that it is decreasing in the substitutability of worker types. This cost of search is then decomposed into three components: unemployment, vacancy costs and mismatch. Our contact technology rules out congestion effects between different worker types and therefore exhibits increasing returns to scale. One third of those increasing returns in contacts are shown to be absorbed by firms and workers being more choosy. The resulting equilibrium is not efficient. Unemployment benefits can reduce the loss by serving as a search subsidy. Numerical simulations of the model show that our Taylor expansions are quite accurate. 相似文献
There is a tradition in the Netherlands to publish an annual ranking of economic and business researchers working in Dutch universities. The most recent such ranking, published in 2013, emphasizes research quantity over research quality. We propose an alternative ranking based on quality. Important information about a researcher’s quality and impact is lost when moulding it to fit a template of numbers. Our ranking is no exception. Nevertheless, we argue and demonstrate that our ranking fits international consensus on research prominence and that the 2013 ranking does not. 相似文献
Integration is one of the important concepts in supply chain management. Both in theoretical and empirical contributions, it is shown that integrative practices improve supply chain performance. Our knowledge with respect to which integrative practices are appropriate under different circumstances is limited. This paper develops propositions regarding the influence of business conditions and the type of resources on integrative practices in links between buyers and suppliers. We will study nine business units and the relationship with their key buyers. For each unit, we will investigate the business conditions, the employment of resources for key buyers and the type and level of integrative practices. Higher complexity in business conditions requires higher levels of integration (specifically in the areas of planning and organisation), which are stimulated by buyer-focused resources and restricted by shared resources. In case of lower complexity, we find lower levels of integrative practices. Here, the influence of shared resources on integration is limited. 相似文献
Abstract Although researchers and practitioners have come up with many good ideas for improving the employment relationship, there is no evidence for universally applicable practices. Prior theoretical work and research in the area of (international) human resource management indicate that cultural and contextual constraints are responsible for the problematic nature of transference of practices. This study illustrates and explains the contextual as well as cultural boundaries through a direct comparison of practices as used in a matched sample of industrial companies in China (n=97) and The Netherlands (n=47). It is argued that differences in organizational structure, cultural values and labour regulations account for the variation between countries. The results show considerable differences between China and The Netherlands in the HRM practices of industrial enterprises. Also, the organizational culture of the companies studied varies between the two countries and the differences found are clearly in line with differences on the national cultural level. 相似文献
Socio‐emotional wealth (SEW), defined as the firm's non‐financial aspects meeting the family's affective needs, has become the dominant paradigm in family firm research. Recent debate acknowledges potential SEW heterogeneity within family firms. This study considers the effect of polarizing opinions on SEW preservation among TMT members as a source of separation in the TMT. More concretely, we study the effect of SEW separation on TMT decision‐making quality, while taking into consideration behavioural integration as a team process and psychological safety as a team context. Based on a unique multiple respondent sample of 300 managers from 55 Belgian private family firms, we find that behavioural integration mediates the negative effect of SEW separation on TMT decision‐making quality. In addition, we find that the negative effect of SEW separation on behavioural integration is mitigated by psychological safety and even turns into a positive effect at high levels of psychological safety. 相似文献
This paper investigates the impact of negative screening on the investment universe as well as on financial performance. We come up with a novel identification process and as such depart from mainstream socially responsible investing literature by concentrating on individual firms’ conduct and by studying a much wider range of issues. Firstly, we study the size and financial performance of fourteen potentially controversial issues: abortion, adult entertainment, alcohol, animal testing, contraceptives, controversial weapons, fur, gambling, genetic engineering, meat, nuclear power, pork, (embryonic) stem cells, and tobacco. We investigate an international sample of more than 1,600 stocks for more than twenty years. We then analyze the impact of applying negative screens to a market portfolio. Our findings suggest that the choice for negative screening strategies does matter for the size of the investment universe as well as for risk-adjusted return performance. Investing in controversial stocks in many cases results in additional risk-adjusted returns, whereas excluding them may reduce financial performance. These findings suggest that there are opportunity costs to negative screening. 相似文献
In spite of the EU's prohibition on brand placement in children's programmes, it is argued that children may still be exposed to this advertising format in many occasions. Consequently, and as children may have even more difficulties than adults to distinguish the commercial content from the editorial media content in which it is embedded, an advertising disclosure may be necessary to enable them to cope with brand placement. Entailing two one-factorial between-subjects experiments, the current article examined how different types of brand placement warning cues influenced cognitive advertising literacy and the attitude toward the placed brand, among children between 8 and 10 years old.
In a first study, it was investigated how these outcomes were influenced by warning cues with different perceptual modalities (no vs. auditory vs. visual cue, N = 98). The results showed that a visual warning cue was more effective than an auditory warning cue (vs. no warning cue) in addressing cognitive advertising literacy. However, this higher cognitive advertising literacy could not account for the effect of the visual warning cue on brand attitude.
In a second study, it was examined whether the effectiveness of this visual warning cue was influenced by the timing of disclosure (cue prior to vs. during media containing brand placement, N = 142). Additionally, it was tested whether the effect of the cue on brand attitude could be explained by cognitive advertising literacy if children's sceptical attitude toward the brand placement format was taken into account. The results showed that cognitive advertising literacy was higher when the cue was shown prior to than during the media content. This cue-influenced cognitive advertising literacy resulted in a more positive brand attitude, but only among children who were less sceptical toward brand placement. This positive relation disappeared among moderately and highly sceptical children.
These findings have significant theoretical, practical and social implications. 相似文献
