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

Income smoothing, as defined in Statistical Activity Cost Theory (SACT), is the rational statistical adjustment of periodic accounting earnings to reduce their time volatility around average long-term profit per period. This article demonstrates how overhead cost allocations can be applied to smooth accounting earnings optimally in accordance with this definition. Such an approach parallels earlier work, such as that by Lane and Willett (1997 , 1999 ), in which a depreciation formula was derived and applied for this purpose. In particular, it is shown that, to realize an income smoothing effect in profit making firms, the usual optimal strategy is to over-allocate costs, giving support to the accounting principle of conservatism.  相似文献

Background:

Telaprevir (TVR,T) and boceprevir (BOC,B) are direct-acting antivirals (DAAs) used for the treatment of chronic genotype 1 hepatitis C virus (HCV) infection. This analysis evaluated the cost-effectiveness of TVR combined with pegylated interferon (Peg-IFN) alfa-2a plus ribavirin (RBV) compared with Peg-IFN alfa-2a and RBV (PR) alone or BOC plus Peg-IFN alfa-2b and RBV in treatment-experienced patients.

Methods:

A Markov cohort model of chronic genotype 1 HCV disease progression reflected the pathway of experienced patients retreated with DAA therapy. The population was stratified by previous response to treatment (i.e., previous relapsers, partial responders, and null responders). Sustained virologic response (SVR) rates were derived from a mixed-treatment comparison that included results from separate Phase III trials of TVR and BOC. Incremental cost per life year (LY) gained and quality-adjusted-life-year (QALY) gained were computed at lifetime, adopting the NHS perspective. Costs and health outcomes were discounted at 3.5%. Uncertainty was assessed using deterministic and probabilistic sensitivity analyses. Sub-group analyses were carried out by interleukin (IL)-28B genotype.

Results:

Higher costs and improved outcomes were associated with T/PR relative to PR alone for all experienced patients (ICER of £6079). T/PR was cost-effective for each sub-group population with high SVR advantage in relapsers (ICER of £2658 vs £7593 and £20,875 for partial and null responders). T/PR remained cost-effective regardless of IL-28B sub-type. Compared to B/PR, T/PR prolonged QALYs by 0.57 and reduced lifetime costs by £13,960 for relapsers. For partial responders T/PR was less costly but less efficacious than B/PR, equating to an ICER of £128,117 per QALY gained.

Limitations:

No head-to-head trial provides direct evidence of better efficacy of T/PR vs B/PR.

Conclusion:

T/PR is cost-effective compared with PR alone in experienced patients regardless of treatment history and IL-28B genotype. Compared to B/PR, T/PR is always cost-saving but only more effective in relapsers.  相似文献

Despite the increasing recognition of the salience of core competencies in the process of competition, the notion of core competencies has remained largely ambiguous in the literature. Neither is it clear what strategies, institutions, and resources are necessary for developing and sustaining core competencies. This paper uses the binary-logit model to explore the determinants of core competencies, and identifies investment in intangible assets, marketing/promotional activities and firm size as significant determinants of core competencies. An evaluation of the technology strategies of two competence-seeking firms also points to the increasing salience of intangible assets, decentralization/globalization of the R&D function, and the intensive search for knowledge and capabilities.  相似文献

The intrinsic motivation of a firm’s management for engaging in prosocial behavior is an important determinant of a firm’s social conduct. I provide the first model in which firms run by morally motivated managers engage in corporate social responsibility (CSR) in a competitive setting. Moral management crowds out a competitor’s strategic CSR, increasing profitability and leading shareholders to strategically delegate moral managers, although necessary for socially optimal CSR is that shareholders be morally motivated as well. Shareholders appoint managers that engage in a socially excessive amount of CSR, counter to existing literature, whenever product‐market competition is sufficiently intense.  相似文献

Multinational Activity and CEO Compensation: Preliminary Evidence from Large UK Firms. — Since the early 1980s the rate of growth in executive remuneration has consistently outpaced that of average earnings. This phenomenon has been widely assumed to be part of an internationalization of the executive labor market. This paper starts from the premise that the multinational enterprise will be a major agent in such a market and presents some preliminary tests for the impact of multinational activity in general, and specific regional effects in particular, on CEO remuneration using a sample of large UK firms. Surprisingly, we find no evidence to support our conjecture that CEO pay will be positively related to firm involvement in the United States. However, multinational activity does generate a significant premium over purely domestic activity.  相似文献

Previous theoretical work suggests that it is appropriate to adjust the CAPM for information contained in analysts' earnings forecasts. This paper uses non-parametric statistical methods to test the relation between estimation risk and security returns. The evidence supports the theory that neglected firms earn abnormally high risk adjusted returns.  相似文献
