A bstract . The use of benefit-cost analysis in federal water resources planning is examined. In addition, its role in the decision-making process is assessed. An argument is made that its use might be more effective if government planners at the sub national level were better trained in economics. The costs of such investments in the quality of water resource planners are shown to be inconsequential with respect to the costs of inefficient projects. In addition, it is argued that investments in high quality analysts at the Washington, D.C.- level may be of less consequence because of the decentralized nature of the decision-making process.  相似文献

A Danish survey with 1,003 respondents, reporting in detail on 278 cases of complaints to the place of purchase of a product or service, shows that consumers with a short education obtain as good results from complaining as do consumers with a longer education. They also have the same propensity to complain in case of dissatisfaction.The bias among complainers therefore seems to be associated with the fact that consumers with short education have a much smaller propensity to be dissatisfied.
Was Verbraucher von Reklamationen im Geschäft erwarten und was sie tatsächlich erhalten
Zusammenfassung Der Beitrag berichtet über eine für Dänemark repräsentative Studie mit 1003 Befragten und 278 Fällen von Reklamationen bei Gütern oder Dienstleistungen. Dabei zeigt sich, daß Verbraucher mit niedrigerer Bildung ebenso gute Ergebnisse bei Reklamationen erzielen wie Verbraucher mit höherer Bildung. Tabelle 4 faßt die erwarteten und erzielten Ergebnisse in Form einer Kreuztabelle zusammen. Auf Grund dieser Daten können drei verschiedene Fallgruppen unterschieden werden.1. Fälle, wo die Reklamation zu dem erwarteten Ergebnis führte.2. Fälle, wo die Reklamation nicht zu dem erwarteten, aber auch zu einem Ergebnis führte.3. Fälle, wo die Reklamation ganz ohne Erfolg blieb.Bei den Gruppen 1. und 3. war der Anteil von Beschwerdeführern mit einer Schulbildung bis zu 9 Jahren 31% bzw. 32%.Tabelle 3 zeigt, daß die Bereitschaft zur Reklamation nicht von der Länge der Schulbildung abhängt, wenn ein Kauf zu subjektiver Unzufriedenheit geführt hat.Wie Tabelle 2 zeigt, liegt das Problem vielmehr darin, daß Verbraucher mit kürzerer Bildung in geringerem Ausmaße Unzufriedenheit empfinden als Verbraucher mit höherer Bildung.

This article investigates the factors that are important to humanitarian organizations when determining locations for inventory prepositioning in preparation for emergencies—a critical decision faced by humanitarian managers. Current research in the sector is rich with mathematical models that focus on this decision, although these models have a limited scope in terms of decision factors. Through a Delphi study our article investigates, identifies, and orders a comprehensive set of factors that decision makers in the humanitarian sector take into consideration when determining where to preposition inventory on the global level. Through this process, 10 main factors are identified, with the top five factors being required: speed of emergency response, the availability and quality of infrastructure, the availability and quality of business support services, the cost of operating the facility, and the availability and quality of labor. We also include suggestions for facility location research based on the outcomes of our study.  相似文献

This paper examines the causal link that runs from classroom quality to student achievement using data on twin pairs who entered the same school but were allocated to different classrooms in an exogenous way. In particular, we apply twin fixed‐effects estimation to assess the effect of teacher quality on student test scores from second through eighth grade of primary education, arguing that a change in teacher quality is probably the most important classroom intervention within a twin context. In a series of estimations using measurable teacher characteristics, we find that (a) the test performance of all students improves with teacher experience; (b) teacher experience also matters for student performance after the initial years in the profession; (c) the teacher experience effect is most prominent in earlier grades; (d) the teacher experience effects are robust to the inclusion of other classroom quality measures, such as peer group composition and class size; and (e) an increase in teacher experience also matters for career stages with less labor market mobility, which suggests positive returns to on‐the‐job learning of teachers.

ABSTRACT

While companies usually prefer private to hybrid governance, they sometimes transfer governance to governments. This paper assumes that this emerges from a decline in a firm’s relative market position. It tests this assumption in a two-stage qualitative analysis: First, it conducts a fuzzy-set QCA of these decisions based on BP’s Annual Company Reports. Second, it presents a process tracing of the voluntary self-nationalisation of the Anglo-Persian Oil Corporation. The paper produces three core findings: First, threats to a company’s survival enable a preference reversal in favour of governmentalisation. Second, shareholder dissatisfaction is a crucial motivator for governmentalisation. Third, managers with an entrepreneurial role-model are more sensitive to autonomy costs and more likely to opt for unconventional governance options.  相似文献

Over the last decade, dividends have become a standalone asset class instead of a mere side product of an equity investment. We introduce a framework based on polynomial jump‐diffusions to jointly price the term structures of dividends and interest rates. Prices for dividend futures, bonds, and the dividend paying stock are given in closed form. We present an efficient moment based approximation method for option pricing. In a calibration exercise we show that a parsimonious model specification has a good fit with Euribor interest rate swaps and swaptions, Euro Stoxx 50 Index dividend futures and dividend options, and Euro Stoxx 50 Index options.  相似文献

Background: Continuous prophylaxis for patients with hemophilia B requires frequent injections that are burdensome and that may lead to suboptimal adherence and outcomes. Hence, therapies requiring less-frequent injections are needed. In the absence of head-to-head comparisons, this study compared the first extended-half-life-recombinant factor IX (rFIX) product—recombinant factor IX Fc fusion protein (rFIXFc)—with conventional rFIX products based on annualized bleed rates (ABRs) and factor consumption reported in studies of continuous prophylaxis.

Methods: This study compared ABRs and weekly factor consumption rates in clinical studies of continuous prophylaxis treatment with rFIXFc and conventional rFIX products (identified by systematic literature review) in previously-treated adolescents and adults with moderate-to-severe hemophilia B. Meta-analysis was used to pool ABRs reported for conventional rFIX products for comparison. Comparisons of weekly factor consumption were based on the mean, reported or estimated from the mean dose per injection.

Results: Five conventional rFIX studies (injections 1 to >3 times/week) met the criteria for comparison with once-weekly rFIXFc reported by the B-LONG study. The pooled mean ABR for conventional rFIX was slightly higher than but comparable to rFIXFc (difference=0.71; p?=?0.210). Weekly factor consumption was significantly lower with rFIXFc than in conventional rFIX studies (difference in means?=?42.8–74.5?IU/kg/week [93–161%], p?Conclusion: Comparisons of clinical study results suggest weekly injections with rFIXFc result in similar bleeding rates and significantly lower weekly factor consumption compared with more-frequently-injected conventional rFIX products. The real-world effectiveness of rFIXFc may be higher based on results from a model of the impact of simulated differences in adherence.  相似文献

The objective of this study is to describe the ‘empirical characteristics’ of scholarly journals in hospitality and tourism research by assessing selected journals. A sample of scholarly journals was selected on the basis of journal ranking lists. The ‘empirical characteristics’ assessed in this study were found to be variable across the studied journals.  相似文献
