When producing International Financial Reporting Standards (IFRS), one of the main goals of the International Accounting Standards Board (IASB) was to create a set of standards which were more useful to investors as a predictive tool. We assess the success of the IASB in achieving this goal by investigating the effects of the introduction of IFRS on the relative information content of reported earnings and forecasted earnings under UK generally accepted accounting practices (GAAP) and IFRS. Results indicate that the value relevance of forecasted earnings is significantly lower under IFRS while the value relevance of reported earnings is significantly larger. These findings suggest that IFRS substitutes price‐relevant information previously provided to the market in the form of analyst forecasts with information encoded by companies in their reported earnings. This implies that the IASB was indeed successful in its stated goal and points towards IFRS forecasts being more accurate and less dispersed than UK GAAP forecasts. This, in turn, implies that analysts are able to provide more informative forecasts under IFRS than under pre‐IFRS regimes and that the aforementioned substitution effect is not a consequence of any decrease in the quality of forecasts under the new regime.  相似文献

Organizations are becoming more and more aware of how important it is to strengthen the competences of their project managers. This fact acquires greater relevance in the development and international cooperation sector because of the need to have qualified professionals who can take up the challenges and address the specific demands of an ever more demanding and constantly evolving sector. This article provides the results of research that more than 100 experts in project management and administration participated in to detect which competences are the most relevant in this context.  相似文献

We examine how the interaction between education and corruption affects institutional reform and economic development. While corruption reduces average income and education, education increases not only output and hence potential corruption rents, but also produces more informed electorates that better monitor government actions. We find that economies with intermediate levels of education remain in a poverty trap since the level of skills creates sufficient corruption rents but not enough monitoring. Economies with low or high levels of education can escape the poverty trap, and inequality plays a key role in determining whether this occurs through a change in institutions or an expansion of education.  相似文献

Evidence is provided on the PPP hypothesis using a sample of 50 Spanish cities for a long time period through the application of panel data unit root tests. Although results suggest non-rejection of the PPP, short-run deviations – as measured by half-lives – indicate that real factors might be causing a slow rate of convergence to a common price index, even in highly integrated economies.  相似文献

This paper provides evidence that audit reports convey relevant evidence for inferring the existence of underlying, unrevealed, financial imbalances. Unlike previous works, which studied US listed-firms bankruptcy, our research deals with Spanish non-financial SMEs under financial stress. Our results indicate that the audit of distressed SMEs has several distinctive features: higher auditor rotation, more qualified reports, and non-compliance with deadlines to approve and file the annual financial statements. We use this evidence to build and test a parsimonious and reliable forecast model. Several implications for auditors’ independence, information quality, and failure forecast are discussed.  相似文献

Research conducted over past decades has investigated selected service encounter behaviors from either a customer or service provider perspective. However, a comprehensive, dual‐perspective framework is lacking. Such a framework is needed to organize knowledge of these behaviors, and thereby provide structure, clarity, and parsimony to the field. This paper describes a three‐tier framework of service encounter behavior that was developed by applying grounded theory principles to interviews with customers, service employees, and other stakeholders. These informants described many ways in which they behave when executing service exchanges, dealing with service difficulties, and managing themselves in the process. Using an iterative inductive approach, a conceptual framework was developed in which specific (Tier 1) behaviors were placed within broader (Tier 2) categories, and these lower classification levels were, in turn, interpreted within a conceptual space defined by the (Tier 3) dimensions of task, relationship, and self. This framework was then elaborated and refined by reference to the psychology and marketing literature, a set of 157 audio‐recorded service interactions, and an expert panel study. The paper includes comparisons between the framework and those previously proposed, propositions regarding service encounter processes and outcomes, and implications for future research and practice.  相似文献

We analyze licensing contracts between informed innovators and developers exerting profit‐increasing effort. Those contracts must simultaneously induce innovators to convey information on the value of their ideas, while inducing developers to exert effort and protecting the innovators' intellectual property rights. We show that the best innovators signal themselves by taking more royalties even if it reduces the developers' share of returns and their incentives. Moreover, royalties are more likely to be used when property rights are easy to enforce and pre‐contractual evidence on innovation quality is hard to produce.  相似文献

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.  相似文献
