There is a rising trend among companies to publish their sustainability or corporate social responsibility (CSR) reports. Assurance of these reports is a valuable voluntary tool to provide them with higher credibility. Nonetheless, the quality of assurance reports differs in practice and the objective of this paper is to provide evidence in this new area of research. Indeed, we are pioneers in developing an index to measure the quality of assurance reports. We choose the Spanish setting because it is the worldwide leading country as regards CSR reporting (KPMG, 2011; Sierra et al., 2012). We have found evidence on the determinants for CSR reporting posited by existing literature that have an impact on (a) the decision of companies to publish their CSR reports, (b) the decision to assure the CSR report or not and (c) the decision to hire the assurance services from an auditor or a consultant and the subsequent quality of the assurance report. Last but not least, our results from a sample of 161 CSR assurance reports evidence that assurance reports are of fairly acceptable quality, according to the index proposed. Furthermore, the value of the quality index is significantly higher if the assurance services are provided by an auditor (as opposed to a consultant) and if the CSR reporting company is larger.

The airport problem is a widely studied allocation problem, with the aim of providing simple and fair sharing rule for the landing fees. In this note we introduce some fairness criteria and characterize the classical Baker-Thompson allocation rule.  相似文献

Modern science is characterized by an increasing trend in collaborations and interactions among researchers. This paper aims to analyse the effects of this phenomenon on the productivity of the science sector and on the growth rate of the economy. Basic research is modelled as a contest where only those who arrive first at an innovation obtain the reward and where the interactions among researchers do contribute to production of scientific knowledge. An important result is that when interactions are significant multiple steady states emerge. Hence the ‘science globalization’ process could have enhanced the heterogeneity among scientific sectors of different countries. When there are low interactions, policies that increase connectivity could have low or even perverse effect at improving the efficiency of science, the contrary happens in high connectivity environments.  相似文献

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

The aim of this chapter is to run through the history of marketing research applied to measuring the effectiveness of advertising and deepen in all those theories that have shed light on this aspect and have influenced subsequent theories and models. This historical review offers the opportunity of knowing the past and understanding better the present of market research applied to advertising. It is a chronological analysis to present day, which introduces the development of the explanatory models for the functioning of advertising and the theoretical and empirical contributions in this area.  相似文献

The present study investigated the effect of culture on a much-prescribed management practice, that of employee participation in decision making. A survey was conducted among employees from two countries culturally distinct in the dimensions of power distance and individualism, namely Canada and the Philippines. Given eight decision-making scenarios that varied in terms of whether voice and/or choice was given to the employee and in terms of the importance of the outcomes, the respondents were asked about their perceptions of fairness of the procedures and outcomes, satisfaction with the procedures and outcomes, and preference for the decision-making procedures. Results show a highly significant country decision-making mode outcome importance interaction effect, but not in the directions expected. Overall, the Philippine sample registered more positive reactions to participation in decision making, although the Philippines' higher rank in power distance and lower rank in individualism than Canada seem to indicate otherwise. The results, together with a previous study conducted in high power distance-low individualism Mexico, forcefully suggest that employee participation in decision making may be successfully transferred.  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
