In July 2015 the International Financial Reporting Standards (IFRS) Foundation launched its third five year review of its structure and effectiveness of the organisation. In a public call, the Trustees solicited stakeholders’ input on the relevance of IFRS Standards with respect to broadening the IFRS scope and to the impact of new technology, on the consistent application of IFRS and on the governance and funding of the International Accounting Standards Board and the IFRS Foundation. The European Accounting Association (EAA)’s Financial Reporting Standards Committee responded to this request for views by submitting a comment letter based on research-informed opinions. This article provides an overview of this Review of Structure and Effectiveness of the IFRS Foundation and the EAA’s opinions in response to this Review.  相似文献

Patent Breadth, Patent Life, and the Pace of Technological Progress   总被引:8,自引:1,他引:7  
In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a non-infringing innovation displaces its product in the market. We define the length of time until one of these happens as the effective patent life, and show how it depends on patent breadth. We distinguish lagging breadth, which protects against imitation, from leading breadth, which protects against new improved products. We compare two types of patent policy with leading breadth: (1) patents are finite but very broad, so that the effective life of a patent coincides with its statutory life, and (2) patents are long but narrow, so that the effective life of a patent ends when a better product replaces it. The former policy improves the diffusion of new products, but the latter has lower R&D costs.  相似文献

Recent asset-pricing models incorporate jump risk through Lévy processes in addition to diffusive risk. This paper studies how to detect stochastic arrivals of small and big Lévy jumps with new nonparametric tests. The tests allow for robust analysis of their separate characteristics and facilitate better estimation of return dynamics. Empirical evidence of both small and big jumps based on these tests suggests that models for individual equities and overall market indices require incorporating Lévy-type jumps. The evidence of small jumps also helps explain why jumps in the market index are uncorrelated with jumps in its component equities.  相似文献

The importance of involving patients and the public in health care research is globally recognized, but how best to do this in critical care is unclear. The aim of this first published review was to explore the extent and nature of evidence on service user involvement in critical care research and quality improvement. Using the scoping review framework described by Arksey and O'Malley ( 2005 ), a team of service user and critical care researchers searched eleven online databases, reviewed relevant web sites, conducted forward and backward citation searching and contacted subject experts. Extracted data were subjected to a narrative synthesis based on the objectives of the review. Findings from a broad range of evidence support that involvement is becoming more commonplace and that experiences are generally positive. Data extracted from 34 publications identify that involvement is most commonly reported at the level of consultation or participation in project teams, however, the extent to which involvement impacts on projects output remains unclear. Key barriers and facilitators relate to the challenge of recruiting a diverse group of service users, dealing with power hierarchies, being adaptable and effective consideration of the resource requirements. More research is required to identify the most effective methods to support the opportunity for involvement and more thorough reporting of service user involvement practices is strongly recommended.  相似文献

Abstract

In recent years, the validity of the weak form efficient market hypothesis (EMH) has been called into question as several studies have uncovered evidence that technical trading rules have predictive ability with respect to both developed and emerging stock market indices. This study analyses the forecasting power of 2 of the most popular trading rules using index data for a selection of 11 European stock markets over the January 1991 to December 2000 period. The findings indicate that the emerging markets included in this paper are informationally inefficient; these markets displayed some degree of predictability in their share returns, although the developed markets did not. Furthermore, the results point to large differences in the performance of the rules examined; while small size filters consistently outperformed the buy-and-hold strategy in the emerging markets examined even after the consideration of transaction costs, the performance of the moving average rules was erratic and varied dramatically from market to market.  相似文献

ABSTRACT

In this paper, we unify two popular approaches for the definition of actuarial ruin with implementation delays, also known as Parisian ruin. Our new definition of ruin includes both deterministic delays and exponentially distributed delays: ruin is declared the first time an excursion in the red zone lasts longer than an implementation delay with a deterministic and a stochastic component. For this Parisian ruin with mixed delays, we identify the joint distribution of the time of ruin and the deficit at ruin, therefore providing generalizations of many results previously obtained, such as in Baurdoux et al. (2016) and Loeffen et al. (in press) for the case of an exponential delay and that of a deterministic delay, respectively.  相似文献

National health objectives are driven to increase participation rates. Individual health decisions are determined by attitudes, behavior, lifestyles, and government policies. This research, therefore, examined not just the development and delivery of a message targeting individual voluntary behavior change, but the intention of changes in social structures that will facilitate individuals reaching their potential; thus the purpose of this article is to shed light on the uptake of the human papillomavirus (HPV) immunization using the health belief model (HBM). Research was conducted with the use of focus groups by drawing on the framework of the HBM. This research approach is conceptual by nature, based on the virtue of marketing promotion and on HBM literature. Though offering the vaccine free to the general public provides additional evidence to certain groups on the intention to act or uptake of the vaccine, awareness levels were found to be poor despite increased efforts by the government trying to promote this vaccine. There was evidence that social capital and trust can produce effective communication message strategies that reinforce social bonds. This article provides an interesting basis for further investigation; however, as implausible as it seems the article also contributes to the concept of perceived benefits and of self-efficacy.  相似文献

The World Trade Organization (WTO) has since its inception in 1995 produced a cohort of 108 “fully litigated” trade cases. Quantitative and qualitative analysis of this cohort of cases reveal that South Korea ranks first among all Asia Pacific nations in appearances as complainant. Similarly, Korea ranks first among the 13 most litigious WTO members in the relative frequency with which it converts WTO Consultation Requests to formal litigation. Furthermore, its litigation history reflects a strategy to employ the formal WTO litigation venue in the service of two key exports: steel and semiconductors. Through this strategy, Korea has challenged U.S. safeguard measures on steel and defended its own putative subsidization of semiconductor manufacturers from countervailing duties imposed by the United States, European Union, and Japan.  相似文献

Micro and small businesses contribute the majority of business activity in the most developed economies. They are typically embedded in local communities and therefore well placed to influence community wellbeing. While there has been considerable theoretical and empirical analysis of corporate citizenship and corporate social responsibility (CSR), the nature of micro-business community responsibility (mBCR) remains relatively under-explored. This article presents findings from an exploratory study of mBCR that examined the approaches, motivations and barriers of this phenomenon. Analysis of data from 36 semi-structured interviews with micro-business owner-operators in the Australian city of Brisbane revealed three mBCR approaches, suggesting an observable mBCR typology. Each mBCR type was at least partly driven by enlightened self-interest (ESI). In addition to a pure ESI approach, findings revealed ESI combined with philanthropic approaches and ESI combined with social entrepreneurial approaches. The combination of doing business and doing good found amongst participants in this study suggests that many micro-business owner-operators are supporters of their local communities and, therefore, driven by more than profit. This study provides a fine-grained understanding of micro-business involvement in community wellbeing through a lens of responsible business behaviour.  相似文献

Abstract

In recent decades, Australian universities have corporatized. Encouraged by government policies, universities adopted modernization practices that have been widely questioned. ‘Collegial entrepreneurialism’ is an approach that builds on collegial processes to protect academic values from the excesses of modernization. This paper examines the perceptions of business academics about the impacts of modernization in autonomous graduate schools of business. The research was undertaken prior to the most recent wave of higher education reform under which most of these schools disappeared. Their experience of three consequences of modernization, ‘hard’ managerialism, academic consumerism and fragmentation of work, provides insight into whether collegiality and academic values can exist within an entrepreneurial academic unit. Results indicate that overt manifestations of modernization are not threatening to ‘collegial entrepreneurialism’. However, in the absence of academic leadership, the more covert influences of consumerism and fragmentation pose a threat to the survival of ‘collegial entrepreneurialism’.  相似文献
