A Consumer-Based Approach to Designing Product Line Extensions   总被引:1,自引:0,他引:1  
A high proportion of new product introductions entail line extensions (e.g., new flavors, sizes, convenience packs, features) rather than totally new products. An attendant problem with line extending involves the possibility of cannibalization of the firm's current products. Paul Green and Abba Krieger describe an approach for designing line extensions that employs consumer tradeoff data and a variety of search heuristics to find "optimal" extensions that explicitly consider the cannibalization of current offerings. The methodology is applied to a case in which an agricultural chemicals firm is introducing a new soybean herbicide.  相似文献

Appropriate real‐time forecasting models for the US retail price of gasoline yield substantial reductions in the mean‐squared prediction error (MSPE) at horizons up to 2 years as well as substantial increases in directional accuracy. Even greater MSPE reductions are possible by constructing a pooled forecast that assigns equal weight to five of the most successful forecasting models. Pooled forecasts have lower MSPE than the US Energy Information Administration gasoline price forecasts and the gasoline price expectations in the Michigan Survey of Consumers. We also show that as much as 39% of the decline in gas prices between June and December 2014 was predictable. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

We provide empirical tests of a general version of targeting theory that greater scrutiny could lead to executive abuses. Our results show that new CEOs under higher expectations or pressure are more likely to report meeting analyst forecasts; however, this apparent superior performance dissipates after excluding firms having characteristics synonymous with earnings manipulation. We find evidence that new CEOs under greater pressure are considerably more likely to engage in manipulation while the link between expectations and manipulation is much weaker. The results are strongest for new CEOs whose firms report meeting forecasts and do not “walk down” earnings estimates.  相似文献

Major contributors to the obesity epidemic are societal and result from sedentary lifestyles and consumption of high-calorie diets. Previous studies suggest that food choice behavior is socially transmissible. Hence, knowledge of the impact of social influence on calorie intake is critical to improve the understanding about the outcomes of policies related to healthful diets. There is the need to analyze the influence of social networks on choosing food in a public place. Thus, we interviewed groups of food court patrons in an all-you-can-eat college dining hall. Results show individuals dining in a group with at least one obese group member are consuming more calories from high-calorie foods and fewer calories from low-calorie foods. Food-related interactions in a group influenced food consumption. Hence, dining with obese peers likely increases calorie intake.  相似文献

This study explores how supervisor career mentoring contributes to contemporary organizational career development, which strives to foster employees' promotability while strengthening their intention to stay. Specifically, we focus on the implications of career mentoring in team contexts. Applying a multilevel framework, we distinguish between individual‐level differentiated mentoring (i.e., an employee's mentoring perceptions as compared to those of other team members) and group‐level career mentoring climate (i.e., the average perception across all group members). In a workplace setting, we collected data from vocational job starters (N ranged from 230 to 290) and their company supervisors (N ranged from 56 to 68). We find that career mentoring climate positively relates to promotability, more so than differentiated career mentoring. Both career mentoring climate and differentiated career mentoring are positively related to the intention to stay. At the individual level, this relationship is mediated by job satisfaction. We discuss theoretical and practical implications of differentiated and group‐level mentoring.  相似文献

Drawing on and contributing to materialist state theory, the regulation approach and institutional economics for more than three decades, Bob Jessop can certainly be considered one of the foremost Marxist political economists of our time. Recently, he has taken on board the cultural turn in social analysis by developing a highly original cultural political economy of the knowledge-based economy. As a contribution to the further development of a cultural political economy that is sensitive to the cultural dimensions of social life while retaining an emphasis on capital accumulation and state regulation, this article directs attention to the limits of Jessop's approach and suggests possible amendments to the theory. In particular, the article highlights the need to move beyond a concern with regulation towards a cultural political economy of complexity and emergence.  相似文献
