In this paper, we provide a model for diffusion of products, which are available in limited quantity until a known expiration date, after which the unsold products have no value. We consider the case of a performing arts company. The model development is built on the foundation of classical product diffusion model by Bass (1969) and the psychological effect known as the scarcity principle (Cialdini, 1985). Our empirical analysis results show that the proposed model can provide significant improvement in prediction of the products characterized by the scarcity effect. 相似文献

An inequality index is called subgroup decomposable if it can be expressed as a weighted sum of inequality values calculated
for population subgroups plus inequality arising from differences among subgroup means. This paper derives the class of subgroup
decomposable inequality indices that satisfies the Bossert–Pfingsten type intermediate inequality invariance. When the intermediate
inequality equivalence concept coincides with the relative notion of inequality, the derived class becomes the Cowell–Shorrocks
generalized entropy family.
For comments and suggestions, we are grateful to Peter J. Lambert and two anonymous referees. We

Abstract Past empirical studies leave open the question of whether perceived crowding has a positive or a negative effect on shopping outcomes (Eroglu, Machleit, & Barr, 2005; Hui & Bateson, 1991). Based on the premise that shopping is a social phenomenon involving hedonic as well as utilitarian motivation, this study hypothesizes an inverted U-shaped relationship between perceived crowding and consumers' store patronage intentions. Additionally, past research considers the mediating role of emotions in the relationship between perceived crowding and shopping outcomes. In this research, the authors argue that consumers' cognitive evaluations of the store and its merchandise also mediate the perceived crowding?patronage intention relationship. Survey results of actual shoppers (n?=?201) in a hypermarket in India demonstrate that there exists an optimal level of crowding that maximises consumers' store patronage intentions. The effect of perceived crowding on patronage intention is mediated by the emotional dimension of pleasure and store evaluation. Further, the effect of perceived crowding on emotions and evaluations appears to be moderated by consumers' optimal stimulation level. In particular, the inverted U-shaped relationship of perceived crowding with pleasure and merchandise evaluation is increasingly manifested with increases in optimal stimulation level. The results also reveal that the effect of pleasure on patronage intention is stronger for individuals who score high on hedonic motivation than for individuals who score low on hedonic motivation. The article provides potential research and managerial implications of the findings. 相似文献

Brands provide a number of benefits that can make them a powerful tool for the nonprofit sector. Among other things, they make it possible for organisations to convey a consistent overall positioning while tailoring offerings for multiple publics. They also facilitate the development of trust between the nonprofit and its constituencies, provide insulation from competitive pressures and raise the organisation's profile. Brands are not appropriate for all nonprofit organisations, however, and the decision to adopt a branding strategy is one that requires careful consideration. This paper explores the pros and cons of nonprofit branding, and describes the balancing act that managers face when deciding whether and how to adopt abrand.

We address the scheduling problem with the following characteristics: (i) there is a single machine available, (ii) the machine has limited capacity, and (iii) job value deteriorates with time. The problem is motivated from several real world situations, such as, downloading process of web pages, and scheduling of multiplexes. Since the problem is NP-hard, we propose new heuristics based on a multiplicative piece-wise metric as an approximation of the slope of job value deterioration. Computational results show that the proposed heuristics perform better than other existing heuristics for similar types of problems. 相似文献

Retail Shelf Allocation: A Comparative Analysis of Heuristic and Meta-Heuristic Approaches 总被引:1,自引:0,他引:1
This research presents a retail shelf-space decision model that incorporates a nonlinear profit function, vertical and horizontal location effects, and product cross-elasticity. We propose a linear programming formulation of the nonlinear profit function that can solve the shelf-space problem optimally. We describe potential advances in heuristic and meta-heuristic algorithms and compare the approaches through simulations and a field experiment. We discuss the impact of the number of item facings, vertical location, and horizontal location (e.g., we find the vertical location effect is approximately double the size of the horizontal location effect on profit performance). 相似文献
