This paper discusses consequences of violating the normal distribution assumption imbedded in Structural Equation Modeling (SEM). Based on real data from a large sample customer satisfaction survey we follow the procedures as suggested in leading textbooks. We document consequences of this practice and discuss its impact on decision making in marketing. 相似文献

In trying to explain the often painful process of corporate restructuring, fingers are frequently pointed at inefficient management. This gives short shrift, however, to an important result of breaking up large, integrated corporations and selling them in smaller pieces: it makes the capital market more nearly complete, and there are strong theoretical arguments that this enhances value. We report the results of a natural experiment that occurred in the oil and gas industry, in which eleven integrated corporations formed publicly traded partnerships to hold their domestic production properties, yet (with few exceptions) retained most of the partnership units under corporate ownership. This behavior avoids any significant change in corporate governance, and is inconsistent with the tax motive popularly attributed as the reason for forming these partnerships; yet we find that significant positive abnormal returns accrued to stockholders when the formations were announced. The results we observe, therefore, support the theory that additional value can be realized by expanding the set of opportunities available to the investment community. 相似文献

This study brings together findings from different research angles on informal feedback in the workplace. We explore the individual and joint influences of three contextual antecedents of seeking feedback: support for learning, psychological safety, and work pressure. Based on our survey of 138 employees from various organizations, hierarchical regression analyses revealed that support in the work environment positively influenced the quality of the self‐initiated feedback from colleagues and (in particular( from the supervisor. Psychological safety positively related to the quality of the self‐initiated feedback from colleagues. No relation was found between support, psychological safety and the frequency of feedback seeking, however, an indication for the existence of a curvilinear effect of work pressure on the frequency of feedback seeking was found. The study highlights the importance of fostering supportive and psychological safe work environments, so that employees and supervisors will look for and give constructive feedback. Learning in organizations can be stimulated by creating enough time and opportunities for informal feedback, and the results suggest several valuable and promising avenues for future research. 相似文献

Summary This address deals with factors contributing to the inequality of income, with particular reference to the Netherlands and to the U.S.A. Sections 2 and 3 survey the shape of the income distribution curve, and the (possible) impact of the length of the reference period and of capital income on income variance. Section 4 shows the modest contribution of intergroup (compared with intra-group) differences in (mean) income, after classification of income recipients by occupation, age and sex. Special attention is paid to estimation of schooling and intelligence effects in multivariate analysis. All systematic factors taken together appear to account for less than 1/3 of the total income variance, so that a major part of it is still unexplained; mainly entrepreneurial income seems to be responsible for it. Finally, possible changes in income distribution - autonomous or resulting from policy measures -are discussed summarily. 相似文献

Mortality forecasting has crucial implications for insurance and pension policies. A large amount of literature has proposed models to forecast mortality using cross-sectional (period) data instead of longitudinal (cohort) data. As a consequence, decisions are generally based on period life tables and summary measures such as period life expectancy, which reflect hypothetical mortality rather than the mortality actually experienced by a cohort. This study introduces a novel method to forecast cohort mortality and the cohort life expectancy of non-extinct cohorts. The intent is to complete the mortality profile of cohorts born up to 1960. The proposed method is based on the penalized composite link model for ungrouping data. The performance of the method is investigated using cohort mortality data retrieved from the Human Mortality Database for England & Wales, Sweden, and Switzerland for male and female populations. 相似文献

This editorial summarizes and comments on the papers published in issue 11(3) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper proposes spatial and a-spatial indicators to describe the networks of airline companies around the world. The second paper sets forth a two-regime gravity-type model with an endogenous threshold parameter to assess the effect of labour market conditions on interregional migration flows. The third paper utilizes micro-data to explain student migration flows to higher education institutions. The fourth paper is among the first to make use of simulation-based location quotients in a multiregional input–output model. Finally, the last paper provides a purely economic–theoretical model on cooperative limit pricing in the context of spatial competition. 相似文献

This editorial summarizes and comments on the papers published in issue 11(4) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper deals with common factors and spatial dependence in the error term specification of a production function model. The second paper sets forth a New Economic Geography (NEG) model with production activities that vary in their complexity, so as to analyse the impact on specialization patterns across different regions. The third paper measures the efficiency of local public investments using a relatively unknown econometric technique in which the time span over which the variables in the regression equation are measured is increased by one time period every run. The fourth paper adopts a conditional quantile regression approach to determine the impact of people employed in informal jobs on the wage distribution in Colombia and five of its regions. Finally, the last paper proposes and tests two new Bayesian variable selection approaches for spatial econometric models. 相似文献
