Using a sample of European real estate firms over the 2007–2010 period, this study provides some evidence that measurement-related fair value disclosures reduce information asymmetry. We find a negative association between the extent of fair value disclosures and the bid-ask spread, but no association with two additional measures of information asymmetry (zero returns and price impact). Contrary to our expectation, we fail to find evidence that firms using model estimates exclusively benefit the most from such additional disclosure. Analysing measurement errors (the absolute difference between the selling price of an asset and its fair value prior to sale), we find that firms that use model estimates exclusively and provide more measurement-related disclosures have lower errors and more accurate fair value estimates. In other words, if our lack of results is due to investors not using this additional disclosure this is to their detriment.  相似文献

由于500ml左右矿泉水瓶瓶口具有统一的螺纹规格,其次,瓶体的容量也具有接近统一的标准,这就为矿泉水瓶再生设计的开发提供了必要的前提。市场上关于矿泉水瓶的再生设计多利用矿泉水瓶作为盛水的容器,而没有继续探讨其盛放小型垃圾(瓜子壳,纸屑,铅笔屑等)的功能。本文以绿色设计中延长产品生命周期的理念为原则,以联想法、模仿法及组合法等产品设计方法为指导,推出一款全新的使用矿泉水瓶衍生功能的产品,并着重介绍在本设计进行的过程中得出的新的设计方法:系统化条件下的功能衍生法。通过这款设计来说明现有产品衍生出新的功能的可行性,并总结一定的设计经验与设计方法,为以后进行相关设计奠定理论和方法基础。  相似文献

Abstract

Objective: This study aimed to compare the cost-effectiveness of ramucirumab versus placebo for patients with hepatocellular carcinoma who progressed on sorafenib with α-fetoprotein concentrations (AFP) of at least 400?ng/ml in the United States.

Methods: A Markov model was constructed to assess the cost-effectiveness of ramucirumab. Health outcomes were measured as quality-adjusted life years (QALYs). With TreeAge software, the disease process was modeled as three health states: progression-free survival (PFS), progressive disease (PD), and death. Costs were extracted from the REACH-2 trial, and utility was derived from published literature. Incremental cost-effectiveness ratios (ICERs) were calculated to compare ramucirumab with placebo. Probabilistic sensitivity analyses were developed to examine the robustness of the results.

Results: In the base case analysis, ramucirumab therapy had a cost of $55,508.41 and generated 0.54 QALYs, while placebo therapy had a cost of $761.09 and generated 0.47 QALYs, leading to an additional $54,747.32 in costs and 0.07 QALYs. The ICER was $782,104.57 per QALY, which was much higher than the willingness-to-pay threshold of $100,000 per QALY. According to sensitivity analyses, the utility of PD in the two groups was the dominant parameter influencing the ICER.

Conclusion: Although ramucirumab was associated with prolonged survival for patients with advanced hepatocellular carcinoma who progressed on sorafenib treatment with an AFP of at least 400?ng/ml, it is not a cost-effective treatment from a United States payer perspective.  相似文献

This article provides an in‐depth, longitudinal analysis combining real‐time and retrospective data on a set of Mondragon's industrial cooperatives that are organized as international groups. We examine the life cycle of these international cooperative groups, which is expected to evolve differently to that of small‐ and medium‐sized cooperatives that operate exclusively on a local scale. The article is theoretically informed by the cooperative life cycle theory, as well as by recent insights from the degeneration and regeneration theses. Our analysis yields an intricate picture of the evolution of cooperatives faced with a ‘grow‐or‐die’ dichotomy. On the one hand, our findings reject the highly simplistic and deterministic view of the degeneration thesis by demonstrating that these cooperatives can mobilize resources to revitalize cooperative values and practices. On the other, we find that regeneration may not occur in a consistent, sequential fashion as the previous literature suggests, but rather degenerative and regenerative tendencies can occur simultaneously, even leading to long‐lasting, unresolvable situations. In light of this, the article asks future research to draw on power‐aware and politically informed approaches for further understanding of how cooperatives manage the tensions at each organizational stage of their life cycle, and of which organizational actors benefit, and how, from reversing some degenerative tendencies while maintaining others intact.  相似文献

The Royal Swedish Academy of Sciences awarded the Nobel Prize in Economic Sciences for 2014 to Jean Tirole, Toulouse School of Economics (TSE), Toulouse, France ‘for his analysis of market power and regulation’. What commonly characterizes Jean Tirole's work is a combination of rigorous scientific analysis of markets and provision of useful scientific insights and policy guidance for regulation and competition policy in such markets. This paper focuses on two of Tirole's papers, both co-written with Jean-Charles Rochet, which probably best exemplify his policy-oriented research. It summarizes and then explains how the theory that these papers develop led to the implementation of a new policy regulating the payment card industry in the European Union.  相似文献

This paper investigates the reasons why some technologies, defying general expectations and the established models of technological change, may not disappear from the market after having been displaced from their once-dominant status. Our point of departure is that the established models of technological change are not suitable to explain this as they predominantly focus on technological dominance, giving attention to the technologies that display highest performance levels and gain greatest market share. And yet, technological landscapes are rife with technological designs that do not fulfil these conditions. Using the LP record as an empirical case, we propose that the central mechanism at play in the continuing market presence of once-dominant technologies is the recasting of their technological features from the functional-utilitarian to the aesthetic realm, with an additional element concerning communal interaction among users. The findings that emerge from our quantitative textual analysis of over 200,000 posts on a prominent online LP-related discussion forum (between 2002 and 2010) also suggest that the post-dominance technology adopters and users appear to share many key characteristics with the earliest adopters of new technologies, rather than with late-stage adopters which precede them.  相似文献

The South African Life Assurance Company (SANLAM) entered global markets after 1990, with varied success. Contextual pressures exerted a ‘push’ on financial services companies, which led to strategic changes in firm strategy, structure and performance. Theories of internationalisation afford more attention to industrial production internationalisation. This article explores the SANLAM experiences with internationalisation since the early 1990s. Initial internationalisation attempts were less successful, leading to strategic business changes, which led to a change in the globalisation strategy and more success in alternative markets. This article explores the different stages of SANLAM’s internationalisation strategy and what determined eventual success. The article contextualises the SANLAM internationalisation strategy by drawing on aspects of the process theory, the Matthews Linkage, Leverage and Learning (LLL) framework, and the Strategy, Structure, Organisation and Performance (SSOP) analytical framework. The SANLAM case underlines the crucial role of tacit knowledge of the host market as prerequisite for successful globalisation strategies of financial services’ firms.  相似文献
