Researchers’ attentions have recently focused on how salespeople cope with role stress. This study focuses on salespersons’ use of six upward influence tactics (UITs) with the immediate sales manager, and how salespeople use UITs to lessen the impact of two role stressors (perceived role conflict and role ambiguity) associated with the sales job. The study also evaluates the potential moderating role of UITs on relationships between role stress and manager satisfaction and propensity to leave. Analysis of data gathered from a heterogeneous sample revealed differences in use of UITs between salespeople classified as either high or low in role stress. Salespeople who perceive high role conflict employ assertiveness and upward appeal UITs more frequently. Salespeople who perceive high role ambiguity use exchange and coalition-building UITs more frequently. Results also suggest that salespersons’ use of assertiveness and ingratiation UITs exacerbate relationships between perceived role ambiguity and two outcomes: satisfaction with supervisor and propensity to leave. Implications of the study findings for sales managers are reviewed, as are implications for further research. His research interests are in the areas of personal selling and sales management. His work has appeared inJournal of Education for Business, Journal of Marketing Theory and Practice, and various national and international conference proceedings. Jeffrey K. Sager, Ph. D., conducts research in the areas of salesperson turnover and job stress. His work has appeared in theJournal of the Academy of Marketing Science, Journal of Personal Selling and Sales Management, andJournal of Business Research. His research interests are in the fields of strategic management and organizational behavior. His research has been published in theAcademy of Management Journal, Journal of Applied Psychology, and several other journals.  相似文献

A new micro-data set demonstrates that, in urban China, own-built dwellings are 75% larger than state-owned dwellings. A switching regression with endogenous switching demonstrates that families with less privileged positions in the Chinese economy are more likely to inhabit own-built housing. The relationships between family characteristics and dwelling sizes in the own-built and state-owned sectors differ dramatically. However, unobserved characteristics, probably includingguanxi, play crucial roles in both. Depending on these characteristics, families in state-owned dwellings might have two-thirds more living space were they to choose own-built dwellings.  相似文献

This paper presents an econometric analysis of the diffusion of the sulfate pulping process throughout the U.S. pulp and paper industry. A dynamic equilibrium, Gompertz diffusion function is employed to derive a multivariate estimation model which incorporates more information than the traditional approach of estimating the growth rate function alone. The empirical results suggest that the econometric approach provides a useful integration of the technological diffusion process and the comparative static theory of demand. The sulfate pulping process is projected to continue capturing market share at a relatively rapid rate, and could account for 90% or more of total U.S. woodpulp production by the year 2000.  相似文献

Abstract .  In this paper we analyse the influence of characteristics of the income distribution in modelling aggregate consumption expenditure. We model the aggregate consumption relation of a heterogeneous population, using a statistical distributional approach of aggregation, and apply it to UK-Family Expenditure Survey data. A bootstrap test based on a non-parametric estimation methodology, which accounts for the presence of continuous and discrete variables, suggests that the mean and the dispersion of the income distribution significantly influence aggregate consumption expenditure. Also, the parameters of the aggregate relation are time varying. These findings have implications for constructing empirically sound models of aggregate consumption expenditure.  相似文献

Recently economists have become interested in why people who face social dilemmas in the experimental lab use the seemingly incredible threat of punishment to deter free riding. Three theories with evolutionary microfoundations have been developed to explain punishment. We survey these theories and use behavioral data from surveys and experiments to show that the theory called social reciprocity in which people punish norm violators indiscriminately explains punishment best.JEL Classification: C91, C92, D64, H41 Correspondence to: Jeffrey P.

Project Management Characteristics and New Product Survival   总被引:6,自引:0,他引:6  
We develop a conceptual model of new product development (NPD) based on seminal and review articles in order to answer the question, “What project management characteristics will foster the development of new products that are more likely to survive in the marketplace?” Our model adopts Ruekert and Walker's theoretical framework of situational dimensions, structural/process dimensions, and outcome dimensions as an underlying structure. We conceptualize their situational dimensions more narrowly as project management dimensions, allowing us to examine more specifically how project management practices affect the NPD process. In our model, project management dimensions include project manager style, project manager skills, and senior management support. Structural/process dimensions include cross‐functional integration and planning proficiency. Outcome dimensions include process proficiency and new product survival. Our empirical analysis finds support for 20 hypotheses, a reversal of one hypothesis, and nonsignificant results for one hypothesis. These results show that projects are best led by managers with strong technical, marketing, and management skills, using a participative style and enjoying early and continuous support from senior management. These project management dimensions promote cross‐functional integration and planning, which are important to process proficiency and new product survival. Our study suggests two broad conclusions. First, it confirms the links in the extant literature between situational (project management) dimensions, structural/process dimensions, and outcome dimensions in NPD. Second, firms can improve cross‐functional integration and planning through various project management practices. Generally, we find that firms interested in improving both proficiency in their development process and the survival rate of new products should take steps to promote cross‐functional integration and to improve their planning processes. While the linkage between cross‐functional integration and NPD outcomes is well established in the literature, the impact of the planning process on NPD outcomes is a research area ripe with opportunity. Our study highlights three aspects of planning that contribute to NPD outcomes. Plans should be detailed, team members should participate actively in the planning process, and teams should be given flexibility and autonomy to respond to unanticipated issues as they appear.  相似文献

Liquidity in private asset markets is notoriously variable over time. Therefore, indices of changes in market value that are based on asset transaction prices will systematically reflect intertemporal differences in the ease of selling a property. We define and develop a concept of "constant-liquidity value" in the context of a model that is characterized by pro-cyclical volume of trading. We then present an econometric model that allows for estimation of both a standard transaction-based price index and a constant-liquidity index. Our application to the NCREIF database reveals that, in the case of institutional commercial real estate investment, constant-liquidity values tend to lead transaction-based and appraisal-based indices in time, and also to display greater volatility and cycle amplitude. The differences can be significant for strategic investment policy viewed from a mean-variance portfolio optimization perspective.  相似文献

In this study we examine the association among confirming management forecasts, stock prices, and analyst expectations. Confirming management forecasts are voluntary disclosures by management that corroborate existing market expectations about future earnings. This study provides evidence that these voluntary disclosures affect stock prices and the dispersion of analyst expectations. Specifically, we find that the market's reaction to confirming forecasts is significantly positive, indicating that benefits accrue to firms that disclose such forecasts. In addition, although we find no significant change in the mean consensus forecasts (a proxy for earnings expectations) around the confirming forecast date, evidence indicates a significant reduction in the mean and median consensus analyst dispersion (a proxy for earnings uncertainty). Finally, we document a positive association between the reduction of dispersion of analysts' forecasts and the magnitude of the stock market response. Overall, the evidence suggests that confirming forecasts reduce uncertainty about future earnings and that investors price this reduction of uncertainty.  相似文献

This article examines the distributional implications of mandatory longevity insurance when mortality heterogeneity exists in the population. Previous research has demonstrated the significant financial redistribution that occurs under alternative annuity programs in the presence of differential mortality across groups. This article embeds that analysis into a life‐cycle framework that allows for an examination of distributional effects on a utility‐adjusted basis. It finds that the degree of redistribution that occurs from the introduction of a mandatory annuity program is substantially lower on a utility‐adjusted basis than when evaluated on a purely financial basis. In a simple life‐cycle model with no bequests, complete annuitization is welfare enhancing even for those with higher‐than‐average expected mortality rates, so long as administrative costs are sufficiently low. These findings have implications for policy toward annuitization, particularly as part of a reformed Social Security system.  相似文献
