In this paper, we explore ways in which the theoretical constructs of scope and adding up can inform and improve the practice of benefit transfer. Specifically, we examine how the stated preference literature on scope and adding up can inform three critical steps in benefits transfer: study site selection, including studies to select for use in a meta-regression; calibrating benefit functions; and assessing transfer validity. 相似文献

Several methods have been developed for filtering seasonal influences and extreme returns in financial and economic time series. The theoretical support for these approaches is rather questionable since it focuses on the effects of shocks on prices and not on their sources. Removing such effects modifies the true generating system of market dynamics because of the non-proportional character of non-linearity. Thus, taking into account that the underlying process of economic time series is highly non-linear we cannot be certain a priori what the impact of new information will be on the dynamic structure of a system. The main contribution of this paper is to demonstrate using the methodology of simulations the eventual distortions in time series data arising from the arrival of news when agents follow non-linear trading strategies. We argue that if news can really modify the dynamical behaviour of a system, then the methodology of filtering exogenous distortions needs to be re-examined. 相似文献

Several studies have shown a relationship between the stocks of migrants and country-level investment in the home country; however the mechanism through which this relationship operates is still unexplored. We use a field experiment in which participants who are recent immigrants send information about risky decisions to others in their social network in their home country. The results demonstrate how this information influences decisions in the home country. We find that the advice given by family members and decisions made by friends significantly affects an individual’s risky decision-making. 相似文献

Background: A phase III trial evaluated the efficacy and safety of Daklinza (daclatasvir or DCV) in combination with sofosbuvir (SOF) for treatment of genotype (GT) 3 hepatitis C virus (HCV) patients.Aim: This study evaluated the cost-effectiveness of DCV?+?SOF vs SOF in combination with ribavirin (RBV) over a 20-year time horizon from the perspective of a United States (US) payer.Methods: A published Markov model was adapted to reflect US demographic characteristics, treatment patterns, costs of drug acquisition, monitoring, disease and adverse event management, and mortality risks. Clinical inputs came from the ALLY-3 and VALENCE trials. The primary outcome was the incremental cost-utility ratio. Life-years, incidence of complications, number of patients achieving sustained virological response (SVR), and the total cost per SVR were secondary outcomes. Costs (2014 USD) and quality-adjusted life years (QALYs) were discounted at 3% per year. Deterministic, probabilistic, and scenario sensitivity analyses were conducted.Results: DCV?+?SOF was associated with lower costs and better effectiveness than SOF?+?RBV in the base case and in almost all scenarios (i.e. treatment-experienced, non-cirrhotic, time horizons of 5, 10, and 80 years). DCV?+?SOF was less costly, but also slightly less effective than SOF?+?RBV in the cirrhotic and treatment-naïve population scenarios. Results were sensitive to variations in the probability of achieving SVR for both treatment arms. DCV?+?SOF costs less than $50,000 per QALY gained in 79% of all probabilistic iterations compared with SOF?+?RBV.Conclusion: DCV?+?SOF is a dominant option compared with SOF?+?RBV in the US for the overall GT 3 HCV patient population. 相似文献

We identify and analyse several dynamic implications of setting environmental standards such as to balance marginal costs and benefits. The adoption of such a regulatory approach is shown to effect (i) the speed of improvement of abatement technologies; (ii) the direction (in a sense to be defined) of that improvement; (iii) its source and the distribution of the rents from it; and (iv) the rate of development of defensive (averting) technologies. Existing views are thoroughly synthesised in the context of a simple diagrammatic model, several new results are derived and at least one conventional wisdom questioned. The message of the analysis for legislators and regulators is that cost–benefit balancing should be done with care. 相似文献

Much of the literature on authenticity is Western-centric, while little work addresses the concept in the Asian environment. The literature relating to authenticity from Asian tourists’ point of view is even underdeveloped. This study therefore aims to fill the knowledge gap by investigating Chinese tourists’ perspective of authenticity. It also examines tourists’ perceived authenticity as a multi-dimensional construct in a consumer-based model, the relationship with heritage motivation and tourist satisfaction. Findings indicate that Chinese tourists’ perceptions of authenticity are closely related to objective and constructive authenticity. The study demonstrates that heritage motivation has a significant positive influence on perceived authenticity and that perceived authenticity has a strong ability to predict tourist satisfaction. 相似文献

This study aims to explore the determinants and outcome of career competencies. Based on the notion that organizations and individuals have respective obligations in the career management of employees’, this study developed perceived “organizational career management’ (OCM) and “career commitment” as determinants and career satisfaction as an outcome of career competencies. Data were collected in the state-owned hotels in China, and structural equation modeling was used to test the proposed relationships. The findings indicate that both perceived OCM and career commitments have positive, direct effects on career competencies. The findings of this study may benefit both hotels and hotel employees by providing valuable implications. 相似文献

The purpose of this study is to explore the relationships between perceived hotel career management, career competency, and career satisfaction. It also aims to examine the mediating processes through which hotel career management contribute to employees’ career satisfaction. Results from structural equation modeling (SEM) show that career competency mediates the effects of three dimensions of hotel career management (career appraisal, career development, and career training) on career satisfaction. The article concludes with implications for theory development and management practice. 相似文献

This study measured membership changes in private clubs in the United States during the economic downturn from 2008 to 2010. Specifically examined were the changes clubs experienced with their number of members, waiting lists, and attrition rates. A letter was sent via e-mail to the same 1,000 private clubs that were sent a survey in a similar study conducted by Ferreira and Gustafson (2006) The managers of these clubs were members of the Club Managers Association of America. The majority of respondents managed country clubs and member-owned clubs, representing different areas of the United States. An overall response rate of 53% was achieved. Most clubs experienced a decrease in the overall number of members and an increase in annual attrition rate. Fewer clubs reported having a waiting list of members wanting to join. The clubs without waiting lists reported a larger number of membership openings in their clubs. The results of this study suggest the levels of memberships in many private clubs are heavily influenced by economic conditions. An implication from this study is that clubs need to implement membership development strategies during economic downturns because of the decline in the number of members, candidates proposed, and waiting lists during these periods. 相似文献

This study aims to develop a measurement scale for organizational career management (OCM) in China's hotel industry. The scale development procedure includes four steps: developing initial items, implementing purifying measures, data collection, and assessing the reliability and validity of the proposed measurement scale. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are used to test the reliability and validity of the measurement scale thus developed. The development process results in a reliable and valid scale for hotel career management incorporating three dimensions: (1) career appraisal and advice, (2) a career development program, and (3) career training. Given the scarcity of research on career management in China, the measurement scale developed in this study will serve as a foundation for future research. The findings of this study may help to stimulate further empirical research on the relationship between hotel career management and employees’ career commitment and career satisfaction. 相似文献
