Price Asymmetry in the International Wheat Market: Comment 总被引:1,自引:0,他引:1

This article explores the role of metaphor in product development processes and market making. Based on a sociocognitive perspective of innovation dynamics and required learning by market actors, the potential of metaphors for mental model development during new product development (NPD) processes is investigated. Three roles for metaphors as cognitive focusing devices for the co-evolution of producers' and consumers' mental models are inferred: mental model communication, mental model matching, and mental model creation. These roles are illustrated by examples that reinforce the need for creativity in applying metaphors as cognitive focusing devices in NPD and market making. 相似文献

Using time-series cross-section data from the manufacturing sector of the 11 West German 'Bundesländer' (Federal States) from 1970 to 1996, I examine the impact of public capital on private production. My econometric analysis explicitly takes into account four of the most frequent specification issues in the context of time-series crosssection data analysis: serial correlation, groupwise heteroscedasticity, cross-sectional correlation and non-stationarity of data. For all approaches and tested specifications, I find that public capital is a significant input for production in the manufacturing sector. Moreover, I find that differences in public capital endowment can explain long-term differences in productivity across the Bundesländer. One tentative conclusion that can be drawn from this finding is that differences in public capital endowment might also explain a part of the still-existing productivity gap between manufacturing in East and West Germany. However, I emphasise that the existence of positive effects of public capital on private production is a necessary, but not a sufficient condition for concluding that public investments should be boosted in the future. 相似文献

This paper describes how National Committee for Quality Assurance (NCQA) accreditation of a managed care plan can be used as a signal of plan quality. A model is then developed examining the factors affecting the probability that a plan will be accredited. Larger and older plans are more likely to be accredited. For-profit plans are also more likely to be accredited. Competition in the marketplace from other accredited plans increases the probability of a plan being accredited. The results indicate that plans that have lower costs of accrediting as proxied by size and age are more likely to be accredited. 相似文献
