The processes involved in an individual's response to the Delphi method are conditioned by a number of psychological affects. This paper examines aspects of two of these processes: the basis for changing opinions, and the factors related to continued participation in subsequent Delphi rounds. The attitudinal perspective is shown to be promising in explaining an individual panelist's response in the Delphi method. Cognitive dissonance apparently has a significant role to play in bolstering the assimilation of nonconforming respondents. This is, however, complicated by the respondents' perception of the credibility of the feedback received. Careful choice of panels may reduce dropouts, presumably by selecting those with a high degree of ego involvement. Nonetheless, elements of cognitive dissonance apparently lead certain panelists to abandon the Delphi process. It is evident that numerous parallels exist between psychological explanations of attitude change and the behavior of Delphi panelists. 相似文献

It has been claimed that good environmental performance can improve firms’ economic performance. However, because of e.g. data limitations, the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings. We discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green. Then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of Norwegian plants. A pooled regression where observable firm characteristics like e.g. size or industry are controlled for, confirms a positive effect of environmental performance on economic performance. However, the estimated positive effect could be due to omitted unobserved variables like management or technology. When the regression model controls for unobserved plant heterogeneity, the effect is generally no longer statistically significant. Hence, although greener plants tend to perform economically better, the analysis provides little support for the claim that it is because they are greener. These empirical findings further indicate that a conclusion that it pays to be green is premature. 相似文献

The topic investigated competition in marketing as a survival yardstick for small and medium enterprises (SMEs) in Nigeria. The objectives addressed by this study were: (1) identifying different types and intensity of competition that SMEs are exposed to along the life-cycle portfolio in Nigeria; (2) quantifying the strength of SMEs vis-a-vis some foreign enterprises in terms of market competition; and (3) proffering solutions on how best they could match competitively these foreign enterprises. Relevant models and theories were employed in literature to evolve detailed analysis of issues relating to the variables used in terms of competition in marketing and survival of juice-producing SMEs. Two hypotheses were investigated through the survey of 20 prominent Ikeja based SMEs using Cluster sampling, 5-points Likert summated rating scale was adopted, while Yard's formula with 95% confidence level and 5% error tolerance was used. Alternative form validity of the instrument was measured at 0.63 while its reliability was measured at Cronbach's alpha of 0.70. Pearson's product-moment correlation was used in testing hypothesis 1 while standard multiple regressions were used to test hypothesis 2. Findings revealed that there was strong relationship between survival of juice-producing SMEs with forms of competition on a firm's life-cycle; while competition had positive effects on survival components for the enterprises. It was concluded that since competition subsists in any firm's life-cycle, strategies to support operations for survival must be adopted. It was recommended that operators of SMEs have to monitor and manage competition as it affects their businesses positively and/or negatively. 相似文献

针对传统企业并购价值评估模型的局限性,本文从期权的角度阐述了企业并购的期权特性,指出企业并购实质上相当于取得了一个看涨期权;并以连续支付红利的美式期权定价理论为基础,建立了企业并购价值评估的期权定价模型。最后,通过实例论述了如何应用该模型来评估企业并购价值,对实践中企业并购价值的合理确定具有重要的指导意义。 相似文献
