This paper reports on a questionnaire survey about share valuation practices among investors and their intermediaries in Saudi Arabia. The findings suggest that fundamental analysis is used most by investor respondents where a P/E multiple is applied to an earnings forecast to generate a prediction of future price. However, technical analysis is also used to a much greater extent than in developed markets. Finally, the results indicate that quarterly and annual reports as well as newspapers are widely consulted by investors when forming their expectations about share valuations.  相似文献

The authors address the need for supply relationships to generate, support, and respond to discontinuous innovation (DI), noting that established ways of working appear insufficient. The peculiarities of DI are explained and contrasted with well-known concepts within innovation. The need for customer firms to be both closely collaborative with suppliers while also exploring potential, unpredictable DI elsewhere is proposed, by means of strategic dalliances . A model is presented for understanding and exploring this emerging management challenge.  相似文献

We show, using the modified rescaled range statistic, that none of the return series of indices of five European countries, the United States and Japan exhibits long term dependence. This statistic — introduced by Lo (1991) — correct Hurst's (1951) ‘classical’ rescaled range statistic for short term dependence. We also report the classical rescaled range statistic after adjusting the series for short term dependence. This procedure shows, for cases where the results of the modified rescaled range statistic are mixed, that no long term dependence can be found. Simulations indicate reasonable power of this adjustment procedure. Furthermore, we find that estimates of the Hurst exponent, a related measure of long term dependence, are also biased by short term dependence. Simulations show that this measure — that has recently attracted growing interest — cannot distinguish between models with or without long term dependence.  相似文献

Protected areas are key to the conservation of global biodiversity and ecosystem services; however, their success is contingent upon adequate funding. One possibility to increase funding for park management is to “sell” a wider suite of ecosystem services “produced” by protected areas, such as carbon sequestration. We conducted 420 tourist surveys to analyze willingness to pay (WTP) for ecosystem service benefits via a conservation fee in the Tambopata National Reserve in Peru. We also interviewed eight tour operators about their perceptions of the proposed fee. The average stated WTP was 15 USD. Sixty-six percent of tourists stated they would pay 10 USD or more, which, if actually paid, would have resulted in 318,000 USD for park management in 2015. Most respondents stated they would pay an additional fee if it supported biodiversity conservation or local ecosystem services, such as water, but less than 10% of tourists were motivated by carbon sequestration as a reason to pay the fee. Most tour operators supported the additional fee. Our findings suggest that tourists are willing to pay higher fees to support conservation but that interest in paying for additional ecosystem services from parks may not extend to global and intangible benefits such as carbon sequestration.  相似文献

Nonprofit organizations are experiencing a new world of fundraising, marketing, and stakeholder engagement on a scale previously unseen and due largely to social media. This study investigated the extent to which nonprofits craft social media policies using ethical frameworks to guide online activity mindful of this new reality. Assessing the top 100 U.S. nonprofits and their social media policies, this study examined the 80,000 words of text extant within the available 55 nonprofit social media policies and found emergent themes that articulate the current ethical state of nonprofit social media policies. Hand-coding processes yielded themes of engagement, responsibility, privacy, protection, transparency, and respect. Computer-coding additionally aggregated these themes into larger themes of privacy, sharing, communication, accuracy, inaccuracy, engagement, and dialogue. Further analysis explored the ways in which nonprofit social media policies imply a dialectical model of ethical frameworks between legal and dialogic dimensions.  相似文献

This paper addresses the question, whether attribute values derived from a CE study of one nature restoration and preservation project depend on the overall scale of nature preservation activities in which it is embedded. A split-sample CE study was undertaken in which a particular nature preservation project was evaluated in three plausible and strictly different embedding contexts. Respondents' attention was drawn to a varying number of forthcoming substitute preservation projects to be implemented prior to the one in question. Results show that while WTP for the project in focus is sensitive to the presentation of substitute projects as such, there does not seem to be any clear and unidirectional relationship between WTP and the number of substitute projects. Furthermore, effects vary across the project's attributes.  相似文献
