Bonus packs created by manufacturers have been characterized by scholars as special factory packs offering the consumer extra product for the same price or at no additional cost. However, this portrayal may fail to fully capture what consumers actually encounter in stores during and following a bonus pack promotion. Indeed, little is known about the types of products that manufacturers promote as bonus packs and how offers for them are specified, how retailers price them, and also what happens when the offers are discontinued. To address these shortcomings, a content analysis is conducted. The results illustrate a richness to bonus pack promotions that previous views of the topic have not described.  相似文献

Introduction Anaplastic lymphoma kinase (ALK) targeting drugs provide an important option for advanced non-small cell lung cancer patients with this distinct tumor type; however, there is considerable uncertainty as to which drug provides the optimal value after crizotinib treatment. This study estimated the cost-utility of alectinib vs ceritinib from a US payer perspective.

Methods A cost-utility model was developed using partition survival methods and three health states: progression-free (PF), post-progression (PP), and death. Survival data were derived from the key clinical trials (alectinib: NP28761 &; NP28673, ceritinib: ASCEND I and II). Costs included drugs, adverse events, and supportive care. Utilities were based on trial data and the literature. One-way and probabilistic sensitivity analyses (PSA) were performed to assess parameter uncertainty.

Results Treatment with alectinib vs ceritinib resulted in increases of 2.55 months in the PF state, 0.44 quality adjusted life-years (QALYs), and $13,868, yielding a mean cost/QALY of $31,180. In the PSA, alectinib had a 96% probability of being cost-effective at a willingness-to-pay of $100,000/QALY. Drivers of model results were drug costs and utilities in the PF health state. The ICER ranged from $10,600–$65,000 per QALY in scenario analyses, including a sub-group analysis limited to patients with prior chemotherapy and crizotinib treatment.

Conclusions Treatment with alectinib in ALK?+?crizotinib-treated patients increased time progression-free and QALYs vs ceritinib. The marginal cost increase was driven by longer treatment durations with alectinib. This model demonstrates that alectinib may be considered a cost-effective treatment after progression on crizotinib.  相似文献

This paper explores the issue of a simultaneous reduction in tariffs at different stages of a vertically related market where each stage is oligopolistic. When vertically related markets are characterized as a successive oligopoly, reducing tariffs by an equivalent amount on upstream and downstream imports will have a differential effect on market access and hence profits at each stage as a result of a combination of horizontal and vertical effects. These differential effects have implications for the tariff structure post‐trade reform.  相似文献

Non‐profit organizations often seek volunteers to help staff a fundraising event. In the present research, an experimental study assessed volunteering time decisions for a fundraising event following manipulations of opportunity cost valence, opportunity cost avoidability and question order involving donating time and donating money. Opportunity costs represent foregone alternatives sacrificed (e.g. working) when engaging in an activity (e.g. volunteering), with valence of the opportunity cost indicating the appeal (positive or negative) of the foregone alternative and avoidability of the opportunity cost suggesting how easy it would be to forgo the alternative. Prospective donors are often asked to consider both volunteering time and contributing money, and these two questions posed to individuals can be varied in terms of order. The results of the experiment revealed that individuals intended to volunteer the most time when an opportunity cost was negative and avoidable. The lowest time donation intentions occurred when an opportunity cost was positive and less avoidable with individuals also being asked about donating money prior to being asked to donate time. The results highlighted the importance to non‐profit firms of considering opportunity costs potential volunteers face and suggested care in structuring the order of questions involving time and money posed to those individuals.

Abstract

In this article, we propose a finite-state Markov process with one absorbing state to model human mortality. A health index called physiological age is introduced and modeled by the Markov process. Under this model the time of death follows a phase-type distribution. The model possesses many desirable analytical properties useful for mortality analysis. Closed-form expressions are available for many quantities of interest including the conditional survival probabilities of the time of death and the actuarial present values of the whole life insurance and annuity. The heterogeneity or frailty effect of a cohort can be expressed explicitly. The model is also able to explain some stylized facts of observed mortality data. We fit the model to some Swedish population cohort data and life tables compiled by the U.S. Social Security Administration. The fitting results are very satisfactory.  相似文献

The present study investigates the nature of the relationship between Leader-Member-Exchange (LMX) quality and turnover intent in the South Korean hospitality industry. Self-administered survey questionnaires were collected from 232 frontline workers as well as 88 supervisors employed in hotel properties. Prior research has produced mixed results, finding linear relationships between LMX quality and turnover intent in some studies and non-linear relationships in others. Traditional hierarchical regression analyses were performed to test the nature of the relationship in these two samples. We found evidence for a U-shaped curvilinear relationship between LMX and turnover intent for non-supervisory employees, but only a linear relationship for supervisory employees. Conceptual and practical implications and recommendations for future research are provided.  相似文献

Media coverage of income inequality and the economic plight of the middle class fails to analyze the long-term effects of growing inequality and to consider possible solutions. The article examines the literature on media coverage of income inequality and the middle class, and then examines how three competing models, the neoclassical economic model, the propaganda model, and the institutionalist model, explain the inadequate coverage of the effects and solutions.  相似文献

Abstract

The following situation is considered. A fixed number (= n) or sequence of independent trials T 1 T 2,…, T n is given, and in each of these an event E mayor may not occur, It is further observed that the event E occurs a total of k times amongst the n trials T i , (i = l,…, n). It is then required to test the hypothesis H 0 that the probability of the occurrence of E is constant from trial to trial, i.e. H 0 is the hypothesis: p 1 = p 2 = ? = p n = p, if p n (i = 1, …, n) represents the probability that E occurs on the ith trial.  相似文献
