Reppenhagen (Rev Account Stud, 2010) investigates how and through which channels contagion, i.e., accounting methods used by related firms, can influence a firm’s
accounting choice. My discussion focuses on research design choices and the potential effect of factors other than those investigated
in the study. 相似文献

Aims: Patients with psoriasis often undergo treatment with a sequence of biologic agents because of poor/loss of response to initial therapy. With the availability of newer agents like ixekizumab and secukinumab, there is a need for cost-effectiveness analyses to better reflect current clinical practice. This study aimed to assess the cost-effectiveness of a sequence of biologic therapies containing first-line ixekizumab vs first-line secukinumab in patients with moderate-to-severe plaque psoriasis in the UK.Materials and methods: A Markov model with a lifetime horizon was developed to compare the cost-effectiveness of ixekizumab and secukinumab treatment sequences: ixekizumab → ustekinumab → infliximab → best supportive care (BSC) vs secukinumab → ustekinumab → infliximab → BSC. The model used monthly cycles, and included four health states: trial period, treatment maintenance, BSC, and death. At the end of the trial period, responders transitioned to maintenance therapy; non-responders transitioned to the next biologic in the sequence. An annual discontinuation rate of 20% was assumed for maintenance therapy.Results: The ixekizumab sequence provided cost savings of £898 (£176,203 vs 177,101) [year 2015 values] and gained 0.03 more quality-adjusted life-years (QALYs: 1.45 vs 1.42) vs the secukinumab sequence over the lifetime horizon. Probabilistic sensitivity analysis showed an 89.8% likelihood that the ixekizumab sequence would be cost-effective at a threshold of £20,000 per QALY gained.Limitations: The analysis used list prices for drugs rather than confidential, preferentially priced Patient Access Scheme costs. In addition, efficacy input data were based on a network meta-analysis, as there were no head-to-head trials comparing ixekizumab and secukinumab.Conclusion: First-line treatment with ixekizumab as part of a specific sequential biologic therapy for moderate-to-severe plaque psoriasis in the UK provided slight advantages in cost savings and QALYs gained over a similar treatment sequence initiated with secukinumab. In view of the small magnitude of these differences, factors such as patient preferences (e.g. for number of injections) and long-term safety (e.g. related to time on the market) may also be important for clinical decision-making. 相似文献

Does the effect of fuel taxes on clean innovations (e.g. hybrid technology) depend on the legal system’s rigidity? Using 1986–2005 data from more than 1900 firms, evidence suggests that auto-industry firms located in civil law (with more rigid laws) countries increase clean technology patenting more than common law (with more flexible laws) firms when the tax-inclusive fuel price rises. A rigid legal system appears to raise clean technology innovation. 相似文献

Globalization, high growth rates in high-tech industries, growing emerging markets and harmonization of patent institutions across countries have stimulated patenting in foreign markets. We use a simple model of international patenting, where the decision to patent in a foreign country depends on country characteristics and the quality of the patented invention. With access to a detailed database on individual patents owned by small Swedish firms and inventors, we are able to estimate some of these relationships and test their validity. Our results indicate that the propensity to apply for international patent protection increases with indicators of the quality of the invention, technological rivalry and market size in the host market. 相似文献

The authors' analysis of the patenting activity of 472 companies that received private equity investments between 1986 and 2005 provides suggestive evidence of an increase in the effectiveness (though not necessarily the quantity) of their innovative activities. After such companies received private equity backing, the patents they applied for received more frequent citations than patents awarded before the involvement of PE firms. Companies acquired by private equity also show no sign of deterioration in patent “originality” and “generality,” which have been shown to be fairly reliable indicators of the fundamental nature of the research. And while there is no clear pattern of change in the level of patenting activity, corporate patent portfolios become more focused in the years after the private equity investments. The increases in our measure of patent “impact” are greatest in the areas that constitute the companies' historical core strengths. These findings are likely to prove increasingly important as private equity continues its incursions into growth areas of the economy. 相似文献

Risk preferences related to accidents or other situations involving the possibility of multiple fatalities were studied in 87 persons in Sweden belonging to two separate groups with professional or educational knowledge of risk‐ and crisis‐management issues. Use was made of a tradeoff method, the results obtained consisting of von Neuman–Morgenstern utility functions over the range of 0–1000 fatalities. Most of the utility curves for the number of fatalities were found to be convex, implying the majority of subjects to display risk‐seeking behaviour. Implications of the findings for societal risk decision making are discussed, along with prospective areas of application and the possibilities of considering other dimensions than the number of fatalities. 相似文献

This article empirically investigates if firms focusing on service innovation perform better financially than firms not focusing on service innovation. Analysis of the financial performance of 3575 Norwegian firms in the manufacturing industries supports the proposition that firms focusing on service innovation have significantly higher growth of operating results than firms not focusing on service innovation. However, this proposition is not supported in a corresponding analysis of 1132 Norwegian firms in the service industries. We elaborate on these results by investigating a variety of performance measures and by comparing the effects of service innovation between manufacturing and service industries. The article contributes to the service innovation measurement literature and to a better general understanding of the determinants of service innovation performance effects. 相似文献

This essay explains why cost accounting, ethical accountability, and accounting principles are interrelated concepts. During the past two decades, the relationship between accounting systems and discharge of accountability has increasingly drawn the attention of researchers. However, researchers have shown a marginal interest in the inclusion and examination of the theme of cost accounting, and in particular, no interest has been oriented to explore the potential role of cost accounting in serving presentation of the trustful cost information as regards the discharge of accountability. In this essay, we will reason that the traditional discourse of cost accounting is fundamentally different from the managerial discourse of cost accounting. The traditional cost accounting is built upon the ethical, legal, professional, and principle-based discourses. By exploring the differences between the two cost accounting discourses, this essay will reduce the effect of current skeptical views with which quality of our academic education, relevance of our research, and our understanding of the potential role of cost accounting in serving the provision and presentation of trustful information have been seriously undermined. 相似文献

Reflecting on real and perceived differences between European and North American research cultures, I challenge views that ‘European’ research is under appreciated or discriminated against, and caution against isolationist European positions. Instead, I argue that although no distinctive and coherent European tradition or culture really exists, there may be elements of the prevalent research culture that can be turned into an advantage for Europe-based and/or European-trained researchers in helping to influence and improve one, global research conversation. Of course, a range of sub-communities and sub-conversations will and should exist, but there is no reason for these to be based on geography. 相似文献
