Do frequency reward programs create switching costs? A dynamic structural analysis of demand in a reward program

This paper examines a common assertion that customers in reward programs become “locked in” as they accumulate credits toward earning a reward. We define a measure of switching costs and use a dynamic structural model of demand in a reward program to illustrate that frequent customers’ purchase incentives are practically invariant to the number of credits. In our empirical example, these customers comprise over 80% of all rewards and over two-thirds of all purchases. Less frequent customers may face substantial switching costs when close to a reward, but rarely reach this state.

Number needed to treat based on real-world evidence for non-vitamin K antagonist oral anticoagulants versus vitamin K antagonist oral anticoagulants in stroke prevention in patients with non-valvular atrial fibrillation

Aims: Non-vitamin K antagonist oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) are used to prevent stroke in patients with atrial fibrillation (AF). This paper aimed to evaluate the clinical efficacy and safety of NOACs when compared to VKAs by calculating the number needed to treat (NNT) at 2 years using incidence rates and hazard ratios (HRs) derived from a meta-analysis of studies conducted in real-world settings.

Materials and methods: HRs were sourced from a published systematic literature review and a meta-analysis of real-world evidence on the use of NOACs vs VKAs. Rivaroxaban, dabigatran, and apixaban vs VKAs were investigated. The efficacy outcomes included: a composite of ischaemic stroke and systemic embolism (IS/SE), ischaemic stroke (IS), and all-cause mortality. The safety analysis assessed major bleeding and intracranial haemorrhage (ICH).

Results: Superiority of NOACs vs VKAs was observed in 10/15 comparisons. Treating patients with rivaroxaban and dabigatran was associated with a reduced risk of IS and all-cause mortality compared to VKAs, with one death prevented every 22 and 32 patients, respectively, and one IS prevented every 206 and 166 patients, respectively. Rivaroxaban was significantly associated with a reduced risk of IS/SE compared to VKA (NNT: 107). No significant differences were observed between apixaban and VKAs. Dabigatran and apixaban were associated with a reduced risk of major bleeding compared to VKA (NNT: 59 and 38, respectively). No significant difference was observed between rivaroxaban and VKAs regarding major bleeding. Rivaroxaban, dabigatran, and apixaban were significantly associated with a reduced risk of ICH (NNT: 205, 115, and 108, respectively).

Limitations: Heterogeneity in definitions of major bleeding across studies.

Conclusions: The NNT calculation, when approached and interpreted properly, is a practical measure of the effectiveness of a treatment. The calculation based on HRs showed that NOACs are safe and effective alternatives to VKAs in real life.     

The Effects of Working Time, Segmentation and Labour Market Mobility on Wages and Pensions in Ireland

Most research on pay and benefit differences between full– and part–time work focuses on characteristics of part–time workers and part–time jobs. However, part–time jobs are more open to labour market 'outsiders', and such labour market mobility can influence wages. We analyse the effects of working time, gender, segmentation and mobility on wages and pension benefits in Ireland. Both segmentation and mobility influence wages directly, and controlling for segmentation in a wage model eliminates the negative effect of part–time working. The wage effects of labour market mobility differ by gender and labour market segment. Pension entitlement is strongly influenced by gender, working time, labour market segment and mobility.     

The Role and Determinants of Concession Sales in Movie Theaters: Evidence from the Spanish Exhibition Industry

The importance of concession sales in the movie exhibition industry is widely acknowledged among economists and other social scientists that have studied this industry in the past. Despite this recognition, the lack of appropriate data has constrained existing studies that document the role that concessions play in movie theaters. Using detailed weekly movie theater data on concession sales, box office revenues and transaction characteristics from a major exhibitor in Spain, we shed light on the relation between concession sales and the following factors (i) theater attendance, (ii) non-traditional channels of ticket distribution, (iii) audience composition, and (iv) theater and market specific factors.      

Management accounting systems, top management team heterogeneity and strategic change

Institutional and market changes force many organizations across economic sectors to reconsider their strategic position and engage in strategic change. Organizations differ in their ability to realize strategic change, however, which appears to depend on several factors in their strategic management process. In this paper we explore two such factors simultaneously, which are the composition of the top management team and the characteristics of the management accounting system. In particular, the paper investigates how top management team heterogeneity affects strategic change both directly, and indirectly, through the design and use of the management accounting system. Hypotheses are developed and tested through a survey study among 103 Spanish public hospitals. We find significant effects of top management team heterogeneity on the extent and direction of strategic change, and find that the use of the management accounting system partially mediates the relationship between top management team heterogeneity and strategic change. The paper contributes to the extant literature on the complex relationships between strategic change and MAS [Gerdin, J., & Greve, J. (2004). Forms of contingency fit in management accounting research – a critical review. Accounting, Organizations and Society, 29, 303–326], by analysing both extent and direction of strategic change, and by recognizing the importance of top management teams’ use of the management accounting system for strategic change.     

New telecommunications services in Austria : A technology assessment

Public fears have grown up surrounding the uncertain potential benefit or harm of recent rapid technological advances in Austrian telecommunications. A technology assessment was called for, to proffer comprehensive and balanced information on the current state of, and future developments in, Austrian telecommunications. This paper explains the organization of the Austrian PTT, discusses successful new services, considers their relationship to the law and the economy, and analyses their social impact.     

Who are the Stakeholders Now? An Empirical Examination of the Mitchell, Agle, and Wood Theory of Stakeholder Salience

Two environmental accidents in the mining industry provide the context for this study of the Mitchell, Agle, and Wood (1997, The Academy of Management Review 22, 853–886) analysis of stakeholder salience. I examine the reactions of two stakeholder groups: shareholder response is examined in terms of changing share returns and risk; management response through change in disclosure. I find the two decision-makers reacted at different times. Management responded to the first accident, though not the second. Shareholders responded to the second accident alone. My findings support the Mitchell, Agle, and Wood (MAW) assertion that stakeholder status is impermanent, and determined through the eyes of the decision-maker.

International Consumer Attitudes Toward Cloud Computing: A Social Cognitive Theory and Technology Acceptance Model Perspective

The purpose of this article is to examine the factors affecting consumer attitudes toward cloud computing in the United States and Australia. The technology acceptance model and social cognitive theory are utilized to test relationships between technology acceptance model constructs (perceived ease of use and perceived usefulness) with individual characteristics that are shaped by environmental factors as part of social cognitive theory (consumer innovativeness, security concerns, performance expectations, and social networks) on consumer attitudes toward adopting cloud computing services. Consumers in the youth segment are used to test the hypotheses in two different countries (the United States and Australia). The results of the analysis indicate similarities and differences related to behavioral intentions and adoption behavior toward cloud computing services. © 2015 Wiley Periodicals, Inc.
