Insensitivity to scope is an issue of much debate in contingent valuation (CV) even today. Although the literature about insensitivity to scope is abundant, the reasons for it are not yet well known. Through a meta-analysis of CV studies of biodiversity, the treatment of the different possible measures of the quantity of the good is explored in relation to scope sensitivity. Overall, the findings suggest that CV results are sensitive to the amount of the good being valued, although the result depends on how the environmental change is measured. Results support the use of absolute sizes when conducting CV studies. 相似文献

We examine the role of school grades as a signal of worker productivity under different examination systems in relation to
errors that may affect student performance. Firms use school grades as a signal of workers’ effective skills, taking into
account that these evaluations are effected by stochastic shocks. We show that more precise evaluation systems, being associated
with a higher reactivity of wages to school grades, induce students to provide more effort. Low ability students tend to react
less than high ability students. Moreover, individuals with low abilities may prefer less accurate evaluation systems. Nevertheless,
when productivity increases, these systems become less convenient and the number of individuals preferring them diminishes.
Our analysis highlights an important trade-off between centralised and decentralised evaluation systems. On the one hand,
frequent evaluations, typical of decentralised systems, weaken the impact on grades of those errors which influence student
performance and, so, reduce signal noise, while, on the other hand, different teachers generally adopt different performance
assessment standards, leading to noisier evaluations. 相似文献

Intermodal transport has been recognized as a priority by the European Union, that has defined different budget allocations
of investments to improve the shifting from road to intermodal transport, which is more sustainable. In this context, the
main aim of the paper is to discuss the macroeconomic effects, in terms of economic growth, welfare and trade, of these public
investments for combined transport, which aspects have been neglected in literature. A multi-country computable general equilibrium
model has been used. The main results have been that the European Union benefits from these investments, but at international
level, USA and Japan would lose in terms of welfare. Furthermore, the welfare change has been decomposed in its components
and the results show that the trade effects are higher than the allocative effects. The robustness of the results has been
tested over time and by a sensitivity analysis of the exchange rate. 相似文献

The authors report on the development of a novel construct, internal environmental locus of control (INELOC), which captures consumers’ multifaceted attitudes pertaining to personal responsibility towards and ability to affect environmental outcomes. Using data gathered from a sample of consumers, the linkages between INELOC and a wide array of environmental behaviors were investigated. Exploratory and confirmatory factor analyses revealed four first‐order dimensions (“green consumer,” “activism,” “advocate,” and “recycling attitudes”) embedded within a second‐order INELOC factor. Structural equations modeling techniques showed that INELOC was a strong positive predictor of many behaviors. However, the nature of the attitude–behavior relationship varied considerably across behavioral contexts, implying that people do not consistently behave in a proenvironmental manner. © 2012 Wiley Periodicals, Inc. 相似文献

This article aims to evaluate the production line automation projects developed by Brazilian and Colombian companies from the Project Management perspective, through the analysis of the application degree of PMBOK processes, to understand how formal techniques are being employed in these countries and also to identify improvement opportunities, when necessary. Data were collected through a survey. The similarity index between the ten processes, with the highest application degree in the Brazilian and Colombian samples, was 70%. For the processes with the lowest application degree, the similarity index was 60%. No similar study was found in the literature. 相似文献

This paper considers the consequences of a large scale mortality shock arising from a famine or epidemic for long run economic and demographic development. The Great Irish Famine of 1845–1852 is taken as a case-study and is incorporated as an exogenous mortality shock into the type of long-run unified growth theory pioneered by Galor and Weil (1999, 2000), and modelled by Lagerlöf (2003a,b) among others. Through calibration, the impact of such a mortality shock occurring on the cusp of a country's transition from a Malthusian to a Modern Growth regime is then depicted. 相似文献

This article aims to build on previous research analyzing the effects of perceived justice on customers' satisfaction with service recovery and the attitudinal consequences of the recovery strategies firms adopt after service failures occur. The results obtained from a conceptual model developed for the mobile‐phone sector support the idea that justice perceptions positively influence satisfaction with service recovery. Other findings are that satisfaction with service recovery positively affects trust and commitment, and that these two variables, in turn, positively affect overall customer satisfaction. Finally, the results also suggest that positive past experiences mitigate the effects of inadequate service recovery strategies on the quality of the relationship with the customers. © 2010 Wiley Periodicals, Inc. 相似文献

Most literature on economic growth focuses on expenditure in research and development (R&D) because of its ability to produce technological change. Models based on this principle, however, fail to account for the exceptional growth exhibited in recent year by country such as China where R&D expenditure is virtually non-existing and for the lack of growth observed in countries such as Japan where R&D expenditure is significant. We propose a model in which entrepreneurs may be research-based (those incurring R&D expenditure) or imitators (those not incurring R&D expenditure) and show that, when the returns to R&D expenditure are low, such as in many emerging economies, the presence of a high number of imitative entrepreneurs who increase competition and product supply is sufficient to generate economic growth regardless of the distribution of activity between research-based and imitative and in spite of low R&D expenditure. 相似文献

As far as we are aware, this study presents the first comparative analysis of the stock picking and market timing abilities of managers of conventional and socially responsible (SR) pension funds, and of their use of superior information. For the United Kingdom, the results obtained show a slight stock picking ability on the part of SR pension fund managers (although it disappears if multifactorial models are considered), and a negative market timing ability on the part of both SR and conventional pension fund managers (these results hold for multifactorial models controlled by home bias). In relation to the management styles, both conventional and SR pension funds usually invest in small cap and growth values, although it is the SR pension funds that are the most exposed to these styles. We also observed that, while conventional pension fund managers make certain use of superior information to follow stock picking strategies, managers of SR pension funds use superior information to follow market timing strategies. 相似文献
