A probabilistic dealing strategy is proposed which allows all premium brands in an established market to earn nonnegative profits without cooperation. Following the strategy, brands take turns attracting deal-responsive customers. Relative to a reactive competitive strategy, the proposed strategy improves the positions of all premium brands. With use of the strategy, average deal sizes are positively related to a brand's market share, the proportion of quality conscious customers, the proportion of informed customers, the span of regular prices in a market, and the range of customers' acceptable prices. 相似文献

This article shows that unfavorable economic conditions at graduation decrease the likelihood of a good job‐worker match over a worker's subsequent career. Mismatch is quantified in terms of overeducation by both industry and occupation. The German Socio‐Economic Panel and region‐level unemployment rates from 1994 to 2012 are used. Instrumental variables estimates account for endogenous graduation timing. A single percentage point increase in regional unemployment causes an increase in the probability of overeducation of 1.6–1.7 percentage points for university graduates. Effects for technical tertiary education and apprenticeship graduates are smaller. Labor market entry conditions affect workers for up to 9 years after graduation. (JEL J23, J22, E32, I23) 相似文献

This paper chronicles the formation and development of the Global Alliance for Public Relations and Communication Management (GA) up to 2002. It sets the GA's genesis within the context of other internationalisation initiatives undertaken by the wider public relations practitioner community and draws links between the formation of the GA and the emerging phenomenon of globalisation. The paper's intent is to describe the formation of the GA from a historical perspective, to understand the forces that led to its creation and to appreciate the different drivers and motivation of founding members. These factors provide a springboard to consider some of the issues that currently challenge GA, some of which were inherent in the governance model it chose at its inception. 相似文献

In this article, we summarize evidence from observations of engineering teams for the importance of active listening in collaborative design problem solving. We focus on the way speakers use freehand sketching to convey complex design ideas, and how listeners support them whilst they do this. We argue that listeners temporarily redistribute the shared cognitive load of discourse production and comprehension within design teams: whilst speakers are engaged in sketch construction they are unable to take account of listener understanding, and listeners respond intuitively by anticipating and avoiding difficulties in this process. We conclude that this cooperativeness emerges naturally from the operation of effort conserving principles underlying collaborative social interaction, and show that by focusing on the contribution of the listener to the production of creative engineering discourse, this principle can be thrown into sharp relief. 相似文献

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention. 相似文献
