This study shows the market value of gold mining firms contains a premium for the option to close. The sample uses 41 gold mining producers listed on the Australian Stock Exchange from 1987 to 2013. The premium of the market price over the present value of cash flows is isolated and a pooled cross‐sectional regression tests the degree of association between that premium and theoretical option premiums. The results show market prices incorporate a premium reflecting the option to temporarily close operations. The magnitude of the option premium to close depends on whether firms are out or in the money options.  相似文献

This paper examines the relative costs and benefits of International Financial Reporting Standards (IFRS) adoption in the European Union by testing the ability of earnings computed under IFRS to predict future cash flows. The study considers the contribution of net income, comprehensive income and other comprehensive income to the usefulness of earnings to predict cash flows, and it compares IFRS with domestic Generally Accepted Accounting Principles (GAAP). Evidence from a sample of Continental European banks shows that IFRS improve the ability of net income to predict future cash flows. Comprehensive income, too, provides relevant information to predict future cash flows, although with a measurement error which is higher than that in net income for greater lags of time. In our interpretation, these findings are consistent with unrealised gains and losses recognised in other comprehensive income being more transitory and volatile in nature. Overall, our results are relevant to academics and standard setters debating the merits of IFRS adoption and to those who use financial statements and adopt reported earnings to form expectations about future cash flows.  相似文献

Although public space is supposed to be democratic and accessible to all, in reality, such access is inegalitarian and exclusionary. The research aims, therefore, to understand how public space that reflects the imposition of interests of dominant ideologies affects the consumption practices of nondominant ideologies. The qualitative research data were collected in the context of urban cycling through in-depth interviews and observation and are analyzed using a hermeneutical approach. The research explains that, in order to deal with the limits of public space use, these consumers use tactics involving (1) disputes for space, (2) disorganized occupation, and (3) transgressive practices; moreover, there is an overlapping relationship between the agency of consumers and public space.  相似文献

This study presents various risk immunization strategies for fixed-income portfolios, including not only classical measures like duration, convexity, and dispersion but also modern measures such as VaR (value-at-risk) and ES (expected shortfall). Empirical tests are conducted in the Brazilian domestic and international bond market. Because it has had one of highest interest rates since the 1990s, Brazil offers an interesting case study for fixed-income studies. Our results are different for domestic and international bonds. For domestic bonds, using the highest convexity criterion to choose the best portfolio is better than using minimum dispersion, and there is a coincidence between the optimum portfolio selected by the convexity, historical VaR, and ES criteria. For international bonds, our findings indicate that the minimum dispersion strategy performs much better than the maximum convexity strategy. The overall performance of portfolios chosen by minimum VaR and ES criteria is also good, with satisfactory realized returns and squared errors.  相似文献

This article deals with online hotel distribution. Its purpose is to investigate the private sales formula, which has recently emerged as a new business model. Two case studies are presented: Expedia, a leading internet distribution system (IDS), and Voyage Privé, a private sales Website. The study highlights the main features of the private sales formula by means of a cross-case comparison between the two travel Websites. The article ends with some final remarks on the main strengths and weaknesses of the formula as compared to the leading IDS in the online travel market.  相似文献

The ongoing processes of digitalisation in economy and society have certainly important implications, not only for economic growth but also for the future labour market. But, what are the actual effects of this ?Digital Revolution“? Who will be the winners and who will be the losers? This article reviews the current empirical literature and draws relevant policy conclusions. While the growth effects will be substantial, the labour market effects of ICT and broadband technologies and their linkage with industrial production via the “internet of things” are likely to be ambivalent. The authors point to the need for political action with respect to labour market institutions that support workers in adjusting to the rapidly changing work environment in a digital world, and measures designed to reduce the skill gap between “digital natives” and “digital illiterates”. They also identify the need to help increase adoption and use intensity of the new technologies, rather than solely investing in broadband infrastructure.  相似文献

Introduction: Long-term exposure to calcineurin inhibitor-based immunosuppressant (IS) therapy in liver transplant (LT) recipients is associated with renal complications. In the randomized trial H2304, everolimus?+?reduced-dose tacrolimus (EVR?+?rTAC) demonstrated equivalent efficacy and superior renal function compared to standard-dose tacrolimus.

Methods: To evaluate the cost-effectiveness of EVR?+?rTAC vs TAC, in de novo LT patients, a Markov model simulating both liver and kidney function was developed and estimated the long-term outcomes of IS following LT. The analysis used the Italian healthcare payer perspective.

Results: Patients treated with EVR?+?rTAC gained on average 1.92 years and 1.62 quality-adjusted life years (QALYs). The incremental cost-effectiveness ratios (ICER) were €35,851 and €42,567 for LY gained and QALY gained, respectively. For the hepatitis-c sub-population, the ICERs decreased to €22,519 and €30,658, respectively.

Conclusion: EVR?+?rTAC improves survival and quality-of-life and is a cost-effective alternative to calcineurin-inhibitor monotherapy for patients requiring LT.  相似文献

Many people fear that exposure to mobile phone base stations leads to severe health effects. In addition to those fears, many citizens are unsatisfied or even angry about prevailing base station site-selection procedures. In the present study, it was investigated how these emotions, i.e. fear and anger, determine risk and benefit perceptions and the acceptance of mobile communication. Using structural equation modeling, we found that benefit perception and the acceptance of mobile phone base stations were primarily determined by anger. Risk perception, in contrast was influenced by both emotions. In addition, controllability and fairness emerged as important cognitive appraisals, or antecedents, of fear and anger, while certainty was not related to these emotions. In sum, our findings highlight that fear and anger have specific influences on risk, benefit, and acceptance of mobile communication. Furthermore, the study provides an in-depth understanding of the antecedents that lead to emotional responses within the context of mobile communication. Implications for risk communication will be derived.  相似文献

The Exchange Market Pressure (EMP) index, developed by Eichengreen et al. (1994 Eichengreen, B, Rose, AK and Wyplosz, C. 1994. Speculative attacks on pegged exchange rates: an empirical exploration with special reference to the European monetary system, NBER Working Paper No. 4898  [Google Scholar]), is widely used as a tool to signal whether pressure on a currency is softened or warded off through monetary authorities’ interventions or, rather, a currency crisis has originated. In this article we show how the index is sensitive to some assumptions behind the aggregation of the information available (exchange rates, interest rates and reserves), especially when emerging countries are involved. Specifically, we address the way exchange rate variations are computed and the impact of different definitions of the reserves, and we question the constancy of the weights adopted. These issues compound with the choice of a fixed threshold when crisis episodes are identified through the EMP index. As a result, one should exert caution in subsequent econometric analyses where a dependent binary variable is built to identify crisis periods.  相似文献

The purpose of this paper is to provide a constructive criticism of Corporate Social Responsibility (CSR) standards. After pointing out a number of benefits and limitations in the effectiveness of CSR standards, both from a theoretical point of view and in the light of empirical evidence, we formulate and discuss a Paradox of CSR standards: despite being well-intended, CSR standards can favor the emergence of a thoughtless, blind and blinkered mindset which is counterproductive of their aim of enhancing the social responsibility of the organization. We analyze three problems that might underlie the Paradox—namely the problem of deceptive measurements; the problem of responsibility erosion and the problem of blinkered culture. We apply the philosophical tradition of American Pragmatism to reflect on these issues in relation to different types of existing standards, and conclude by suggesting a number of considerations that could help both CSR standards developers and users to address the Paradox.  相似文献
