Public services in the UK are increasingly expected to account for their outputs and performance. This article describes a retrospective evaluation of the benefits from the R&D funded by a regional office of the NHS Executive. The methods adopted enabled the various elements of the region's R&D portfolio to be examined and provided a basis for the development of a plan for regular monitoring. The proposals for implementation are now also feeding into a debate as to how health services R&D might best be monitored nationally in a way that is compatible with the norms and practices of research in other contexts.  相似文献

We examine the stock price reactions of four Swiss banks to negotiations between Switzerland and the European Union and between Switzerland and the United States to (i) obtain an estimate of the value of banking secrecy to Swiss banks, and (ii) distinguish between tax evasion and genuine privacy concerns as sources of that value. We find that the value of banking secrecy to the private banks is large, accounting for 8 to 14% of their market value; in contrast, the value of banking secrecy to the universal banks is small. We further find that tax evasion may be less important and privacy concerns more important a source of value of banking secrecy than might previously have been thought.  相似文献

The estimation of physical intensity processes in the context of default risk is investigated here. Using data from Moody's Corporate Bond Default Database, a term structure of default probabilities for different rating classes is constructed each year from 1970 to 2001. Two specifications used for modeling the dynamics of the (risk‐neutral) intensity process in the bond‐pricing literature are then examined empirically: the Ornstein–Uhlenbeck and square‐root cases. The results reveal that the Ornstein–Uhlenbeck case is not an adequate modeling alternative with a rejection of this specification in five out of seven credit classes and nonsignificant mean reverting behavior for all credit classes. The square‐root case obtains better results with four credit classes out of seven for which this specification cannot be rejected and significant mean reversion parameters in many cases. © 2008 Wiley Periodicals, Inc.

Critical analyses of the audit profession have become more common in recent years. Many of these analyses focus on the entire audit profession in developing their criticisms and concerns. In this paper, the scope of analysis is narrowed to examine in depth the auditing profession's use of the concepts of reasonable assurance and materiality in audit performance and audit communications. Reasonable assurance and materiality are the terms that auditors use to describe the scope of their responsibility to the public. Similarly, reasonable assurance and materiality are the key determinants of audit effort. An overview of official guidance, practitioner reports, and academic research reveals that these two key concepts are not well specified nor are they consistently applied in audit practice. These findings are evaluated from two competing perspectives on professions – the traditional, functionalist perspective and the critical theorists' perspective. Evaluation from the latter perspective leads to a conclusion that the profession's use of these key terms to guide practice and communication leaves the profession open to charges of mystification and unjustified paternalism.  相似文献

Intangibility has long been studied as a unidimensional construct with the focus being placed upon the physical element. This paper explores the effects of three unique intangibility dimensions on a consumer's ability to evaluate goods and services, and the perceived risk (PR) associated with the transaction. The authors examine these relationships in purchase environments that include both traditional bricks-and-mortar retailers and the Internet. Their investigation further incorporates prior knowledge as a moderating factor into the proposed framework. This allows for a thorough comparison of the effects and relationships that exist between intangibility and its consequences in general, evaluation difficulty (ED) and perceived risk (PR) in particular. The authors develop hypotheses pertaining to the proposed model and test them with two experiments. The empirical results are broadly supportive of the hypotheses. Theoretical and managerial implications to the services marketing literature are discussed.  相似文献

Lattice schemes for option pricing, such as tree or grid/partial differential equation (p.d.e.) methods, are usually designed as a discrete version of an underlying continuous model of stock prices. The parameters of such schemes are chosen so that the discrete version “best” matches the continuous one. Only in the limit does the lattice option price model converge to the continuous one. Otherwise, a discretization bias remains. A simple modification of lattice schemes which reduces the discretization bias is proposed. The modification can, in theory, be applied to any lattice scheme. The main idea is to adjust the lattice parameters in such a way that the option price bias, not the stock price bias, is minimized. European options are used, for which the option price bias can be evaluated precisely, as a template to modify and improve American option methods. A numerical study is provided. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:733–757, 2006  相似文献

Although brands offer different kinds of rewards through their loyalty programs, little is known about how they can impact consumer–brand relationships and brand attitude. How do loyalty program rewards influence the consumer–brand relationship? And which kinds of rewards establish or maintain closer relationships between consumers and brands than others? To answer these questions, the present research makes use of self-expansion theory (Aron & Aron, 1986) and two experiments that manipulate the extraordinary character of rewards offered to consumers. Our findings show that special rewards produce higher self-expansion than mundane rewards. Moreover, the positive effect of the rewards’ extraordinary character on brand evaluation, recommendation, and identification is sequentially and fully mediated by self-brand inclusion and self-expansion. Finally, we show that consumer satisfaction moderates the impact of special and mundane rewards on self-brand inclusion.  相似文献

This paper examines how longitudinality is investigated in innovation research. A review of longitudinal methods in innovation articles, published between 2000 and 2011, is undertaken. Our findings show that longitudinal approaches to data collection are gaining some credence, in line with increased criticism of the overuse of positivist methods to study process‐based phenomena. However, results demonstrate a dearth of systematic longitudinal analytical methods employed in product innovation research. Static analytical methods are prominent. These inevitably lead to static presentation of results, and this is borne out in our findings. Second, the paper discusses the conduct and utility of a specific technique for product innovation research: sequence analysis. By drawing on two studies, which apply sequence analysis in product innovation research, sequence analysis is shown to be a useful technique to achieve rigor in analyzing longitudinal data. The paper concludes by discussing how such systematic methods for analyzing longitudinality in the innovation field demand greater usage and exploration.  相似文献
