Sustainable development is nowadays a high priority for firms all over the world. Consequently, numerous firms have increased their social responsibility initiatives, reinforcing the credibility and trust of their stakeholders. However, prior research about the relevance of sustainability leadership for the European investment community is scarce. In this context, the aim of this study is to examine whether sustainability leadership – proxied by membership of the Dow Jones Sustainability Index Europe – is value relevant for investors on the 10 major European stock markets over the 2001–2013 period. Our overall results reveal that there exist significant differences across markets. These findings are relevant especially for investors, but also for the managers of listed firms, market regulators and policymakers. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment 相似文献

The oil and gas industry is subject to different types of risks, many of which have the potential to generate extreme results. Classifying extreme events as global, industry specific and firm specific, we use a Bayesian probability model and the Exponential Generalized Autoregressive Conditional Heteroskedasticity (EGARCH) model to evaluate the impact of disclosure of extreme events on returns and return volatilities. The results suggest political events have more of a pronounced effect compared to those classified as economic events. The overall effects are more pronounced at the global and firm‐level classifications. At the firm level, extreme economic events have a more significant impact than political extreme events. 相似文献

Preservation or Conversion? Valuation and Evaluation of a Mangrove forest in the Philippines 总被引:3,自引:0,他引:3
Mangrove ecosystems are rapidly declining in many parts of the world. This has resulted in the loss of important environmental and economic products and services including forest products, flood mitigation and nursery grounds for fish. The aquaculture industry was the single biggest threat to mangroves in the Philippines until 1981 when conversion of the remaining mangrove stands was prohibited by law. However, the decreasing yield from capture fisheries is putting pressure for the re-examination of this policy. To understand the importance of mangroves, insight is needed into the value of products and services provided is needed. This article compares the costs and benefits of mangrove preservation with those generated by alternative uses such as aquaculture and forestry. Equity and sustainability objectives are taken into account, in addition to economic efficiency and analyzed according to the perspectives of the different types of decision makers involved. 相似文献

This study implements a regular vine copula methodology to evaluate the level of contagion among the exchange rates of six Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico, and Peru) from June 2005 to April 2012. We measure contagion in terms of tail dependence coefficients, following Fratzscher's (1999) definition of contagion as interdependence. Our results indicate that these countries are divided into two blocks. The first block consists of Brazil, Colombia, Chile, and Mexico, whose exchange rates exhibit the largest dependence coefficients, and the second block consists of Argentina and Peru, whose exchange rate dependence coefficients with other Latin American countries are low. We also found that most of the Latin American exchange rate pairs exhibit asymmetric behaviors characterized by nonsignificant upper tail dependence and significant lower tail dependence. These results imply that there exists contagion in Latin American exchange rates in periods of large appreciations, whereas there is no evidence of contagion during periods of currency depreciation. This empirical regularity may reflect the “fear of appreciation” in emerging economies identified by Levy‐Yeyati, Sturzenegger, and Gluzmann (2013). (JEL C32, C51, E42) 相似文献

For many decades the US dollar has remained unchallenged as the world’s dominant international currency. What is behind its
persistent pre-eminence in the international monetary system and can this be expected to last? Could the euro rival or even
surpass the dollar as the leading currency? If it did, what would be the consequences for Euroland?

This work intends to present chaos theory (and dynamical systems such as the theories of complexity), in terms of interpretation of ecological phenomena. The chaos theory applied in the context of ecological systems, especially in the context of fisheries has allowed the recognition of the relevance of this kind of theories to explain fishing phenomena and fisheries policies. It has permitted new advances in the study of marine systems, contributing to the preservation of fish stocks. This paper deals with the way how to manage fisheries taking chaos in account of the problem. 相似文献

After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft, shipping or trucks. The customers are the failures, and their service time is the time that goes from the instant at which they occur till they are completely repaired. The failing repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application, models of Carrillo (1991) and Ferreira (1996) are considered, improved and completed. The theory is illustrated with a numerical example. 相似文献

The historical study of the Spanish nineteenth-century banking system has been almost exclusively carried out through a consideration of the experiences of the joint-stock banks. But the very scarce number of these, and their territorial distribution, makes it necessary for us to look for other financial intermediaries who were able to satisfy the demand for banking services in that time and place. We demonstrate that this role was fulfilled by the banking merchants and banking houses operating through individual firms and partnerships. The object of this work is to make their activities better known and vindicate their importance. The sources used for the study are mainly the accounting documents of several banking houses. 相似文献
