Formative versus reflective measurement models: Two applications of formative measurement 总被引:1,自引:0,他引:1
Tim Coltman Timothy M. Devinney David F. Midgley Sunil Venaik 《Journal of Business Research》2008,61(12):1250-1262
This paper presents a framework that helps researchers to design and validate both formative and reflective measurement models. The framework draws from the existing literature and includes both theoretical and empirical considerations. Two important examples, one from international business and one from marketing, illustrate the use of the framework. Both examples concern constructs that are fundamental to theory-building in these disciplines, and constructs that most scholars measure reflectively. In contrast, applying the framework suggests that a formative measurement model may be more appropriate. These results reinforce the need for all researchers to justify, both theoretically and empirically, their choice of measurement model. Use of an incorrect measurement model undermines the content validity of constructs, misrepresents the structural relationships between them, and ultimately lowers the usefulness of management theories for business researchers and practitioners. The main contribution of this paper is to question the unthinking assumption of reflective measurement seen in much of the business literature. 相似文献

This paper is a brief look at a wide range of risks that are said to present great threats to humankind. It was stimulated by several interacting factors. First, too many books and articles about astrophysical catastrophes, in the scientific and semi-scientific press, give relatively little attention to their timeframe or the measures to anticipate and prepare for them. Second, and most important, is that the overblown effects of 9/11 have distorted the United States of America's perspective and agenda on catastrophes. The result is that billions of dollars have been wasted and attention turned away from threats that could be truly catastrophic for the United States and, in many cases, for the rest of the world. Third, are books that have become popular by raising the threat that what will happen to us will be similar to what happened to earlier societies such as the Maya and the Easter Islanders. Most notably among these is Jared Diamond's Collapse [Jared Diamond, Collapse: How Societies Choose to Fail or Succeed, Penguin Group, 2005]. The failure in these doomsday arguments is to overlook the greater sophistication, knowledge, awareness, monitoring and preparation currently in the United States and in other parts of the globe. The institutional structure and scientific knowledge today would either prevent or deal with the kind of socio-economic decline anticipated by the “collapse” arguments. In contrast several geophysical and celestial risks do imply global catastrophe. The value of this paper is as broad background to the specific scenario papers that follow. While it leans heavily on the work of others, it offers three new features for the analysis of any extreme risk. First is a scale of devastation, based on deaths. Second is a comprehensive time frame—now to the end of the Earth. Third is an outline of general questions that must be addressed for any risk, however large or small, if it is to provide insight into policy choices and promote systemic thinking. 相似文献

abstract Previous research has portrayed buyer–supplier and supplier–supplier alliances as important mechanisms to foster learning and exchange efficiencies. Controversy remains, however, as to how these alliances interact. While some propose they reinforce one another (e.g. learning in horizontal ties generates positive spillovers to vertical ties), others propose a negative interplay (e.g. when increasing vertical-tie intensity, suppliers may weaken horizontal ties to avoid retaliation from buyers who wish to preserve bargaining power). We empirically test these competing views using survey data from the Brazilian auto-parts industry. In an attempt at reconciliation, we propose that the positive or negative interaction between vertical and horizontal alliances depends on the level of technological uncertainty of goods exchanged. Vertical ties seem to inhibit horizontal ties when technological uncertainty is low; when technological uncertainty is higher, vertical and horizontal ties do not seem to have any meaningful form of interaction. We discuss implications for theory and practice. 相似文献

Beladi and Chao (2006) and Bárcena-Ruiz and Garzón (2006) considered the role of environmental policy on the decision whether to privatize a public firm in different market structures. This paper re-examines whether privatization improves (or deteriorates) the environment in a mixed duopolistic framework with differentiated product and pollution abatement. It is shown that, due to privatization, less attention is paid to pollution abatement by all the firms coupled with less environment taxes levied by the government in a differentiated duopoly, and the environment is more (less) damaged when the product is less (more) substitutable. When the product is highly substitutable, industry profits increase because this softens the intensity of the product market, but social welfare deteriorates accompanied with the path of privatization because the loss of consumer surplus and tax revenue exceeds the increases in profits, even if the environment is less damaged. 相似文献

The main purpose of this work consists of displaying the different attitudes of men and women towards organic food, and their willingness to pay for it, in three different consumer intensities: usual, occasional and potential consumers. Several surveys have been carried out to obtain a representative sample of regular food purchasers living in Castilla‐La Mancha (Spain). Statistic analysis previously detecting significant differences with regard to gender and type of consumer has been conducted by univariate analysis to describe attitudes, and multivariate analysis, through ‘logit’ models, to calculate maximum willingness to pay. Results show that women have a more favourable attitude (directly related to their lifestyle) to the purchase and consumption of organic food than men, whereas men are inclined to pay a higher price for organic food than women. In general, men are disposed to pay a higher increase in price than women. 相似文献

Alternative indexes for monitoring customer perceptions of service quality: A comparative evaluation in a retail context 总被引:3,自引:0,他引:3
Customer satisfaction and service quality measures obtained through consumer surveys invariably have skewed distributions.
As such, researchers have questioned the appropriateness of the popular approach of using the mean rating to summarize such
data. However, no detailed study on this topic has yet been conducted. In two independent studies, the relative validity of
the various indexes that can be used to summarize consumer’s service quality ratings (e.g., mean, median, mode, kurtosis,
skewness, top/bottom-tail percentiles) are examined. In Study 1, using typical commercial survey data from a fast-food/convenience
retail chain, both the mean and top-box percentiles are found to be the best indicators of service quality, based on their
correlation with customer-driven business performance measures. In Study 2, the results are further confirmed by an extensive
simulation that varies factors such as the shape of the underlying distribution of customer ratings and the strength of the
relationship between customer ratings and business performance measures. The article concludes with a discussion of the findings
and implications for future research.

Analyzing Real Estate Data Problems Using the Gibbs Sampler 总被引:2,自引:0,他引:2
John R. Knight C.F. Sirmans Alan E. Gelfand Sujit K. Ghosh 《Real Estate Economics》1998,26(3):469-492
Real estate data are often characterized by data irregularities: missing data, censoring or truncation, measurement error, etc. Practitioners often discard missing- or censored-data cases and ignore measurement error. We argue here that an attractive remedy for these irregularity problems is simulation-based model fitting using the Gibbs sampler. The style of the paper is primarily pedagogic, employing a simple illustration to convey the essential ideas, unobscured by implementation complications. Focusing on the missing-data problem, we show dramatic improvement in inference by retaining rather than deleting cases of partially observed data. We also detail Gibbs-sampler usage for other data problems. 相似文献

This study monitors the effects of economic transition on wages and employment in a former Soviet Republic. Estonia's case is of particular interest because of its early adoption of relatively free labour market policies. Relative wages for the highest educated groups rose for all age groups. There were also rapid increases in returns to job experience, particularly at young ages. Increasing wage dispersion across human capital groups was accompanied by narrowing wage dispersion within human capital groups. Relative wages rose in sectors which gained relative employment, while they fell in shrinking sectors. In addition, there were large flows of labour between shrinking and growing sectors, suggesting that labour market equilibrating mechanisms developed very rapidly in Estonia. 相似文献
