Climate change has become an issue which touches upon all spheres of life. To combat the problem, understanding the perceptions of all that have stake in it provides with stronger ground for decision-making. Ethiopia is one those countries that are or going to be severely affected by climate change, the solution of which partly depends on how its key decision-makers perceive the problem. In light of this a questionnaire survey was conducted on 195 volunteering members of the House of People’s Representatives in Ethiopia. The results of data analysis reveal that most identified rainfall variability, declining hydrology and increasing temperature as manifestations of climate change, and emission reduction and forest protection as its key solutions. 相似文献

We explore a large sample of analysts' estimates of the cost of equity capital (CoE) to evaluate their usefulness as expected return proxies (ERP). We find that the CoE estimates are significantly related to a firm's beta, size, book-to-market ratio, leverage, and idiosyncratic volatility but not other risk proxies. Even after controlling for the popular return predictors, the CoE estimates incrementally predict future stock returns. This predictive ability is better explained as the CoE estimates containing ERP information rather than reflecting stock mispricing. When evaluated against traditional ERPs, including the implied costs of capital, the CoE estimates are found to be the least noisy. Finally, we document CoE responses around earnings announcements, demonstrating their usefulness to study discount-rate reactions of market participants. We conclude that analysts' CoE estimates are meaningful ERPs that can be fruitfully employed in a variety of asset pricing contexts. 相似文献

When the underlying stock price is a strict local martingale process under an equivalent local martingale measure, the Black–Scholes PDE associated with a European option may have multiple solutions. In this paper, we study an approximation for the smallest hedging price of such an European option. Our results show that a class of rebate barrier options can be used for this approximation. Among them, a specific rebate option is also provided with a continuous rebate function, which corresponds to the unique classical solution of the associated parabolic PDE. Such a construction makes existing numerical PDE techniques applicable for its computation. An asymptotic convergence rate is also studied when the knock-out barrier moves to infinity under suitable conditions. 相似文献

This paper examines the determinants of consumers’ buying attitudes for houses from January 1984 through June 2005. Data on
buying attitudes are from responses to the Surveys of Consumer Attitudes conducted by the Survey Research Center, University
of Michigan. The determinants considered include current and expected interest rates, wealth, expected real disposable income,
expected change in financial status and house prices. The empirical estimates show that a long-run relationship exists between
buying attitudes for houses and each of the above variables. Each of these determinants also Granger cause buying perceptions.
Generalized impulse responses show that shocks to each of the above variables have a predictable and permanent impact on buying
attitudes. Furthermore, generalized variance decompositions suggest that both current and expected interest rates explain
a large proportion of the variation in consumers’ perceptions towards buying houses. Since consumers’ attitudes towards buying
houses are likely to be translated into actual purchases, this study shows that in order of importance, interest rates—both
current and future—have the maximum impact on decisions to purchase houses followed by expectations of real disposable income.

Gonzalez et al. (2012) apply the Unified Theory of Acceptance and Use of Technology (UTAUT, Venkatesh et al., 2003) to the issue of adoption of continuous auditing (CA) by internal auditors. The authors make a very convincing case for the slow evolution of CA and propose that this can be explained by the four factors contained in the UTAUT as well as annual sales and voluntariness of use. They find, in their revised model, that effort expectancy and social influence directly impact intentions to use the technology, while performance expectancy is moderated by annual sales and social influence is moderated by voluntariness of use. Interestingly, the authors also identify geographical differences in these influences. I offer commentary on these findings and suggest avenues for future research in the domain of technology adoption and use in accounting. 相似文献

Many studies have examined the relationship between various individual variables and people's perceptions of genetically modified (GM) food. A problem with this type of research is that contextual factors are completely ignored. This article explores the use of multi‐level modelling in the field of risk research, by re‐analysing a recent British study of public perceptions of GM food. As the study employed a multi‐stage sampling strategy, it could be used to examine simultaneously the individual and spatial variation in trust and the acceptability of GM food. While the geographical variation in acceptability was largely due to compositional differences between the sampling points, a geographical variation in trust remained after controlling for individual differences. The analysis demonstrated that city‐dwellers commonly have more trust in the regulation of GM food than other respondents. Next to being associated with a number of socio‐demographic variables, both acceptability and trust were related strongly to voting intention. Moreover, the results suggest that there is a link between vulnerable groups, feelings of exclusion, and (dis)trust. The article is concluded by arguing that multi‐level modelling provides new opportunities for simultaneously examining the individual and contextual basis of public perceptions of controversial risk issues. 相似文献

The recent crisis has caused some finance theorists and practitioners to rethink the effects of managerial incentives on the total enterprise value of large financial institutions. This re-examination has identified and analyzed a number of potential problems with the use of equity-based compensation, including insufficiently long managerial time horizons as well as the temptation for excessive risk-taking provided by “asymmetric” payoff structures in which shareholders have virtually all the upside while debtholders bear most of the downside risk. In an attempt to address such problems, finance and governance scholars have increasingly explored the possible value of aligning managerial interests with those of not only shareholders, but other important corporate claimants such as debtholders and taxpayers. After reviewing the latest thinking about risk and managerial incentives at financial institutions, the authors come to the following conclusions:
- • The design of incentives for value maximization needs to reflect a healthy appreciation of downside risk as well as upside reward, and both senior and subordinated debt may be ideal instruments for establishing that balance. At the same time, most senior executives should continue to receive equity-linked compensation in addition to significant proportions of “inside debt.”
- • Since decision-makers below the highest level executives of large financial institutions collectively wield enormous power to assume and manage risks, this “upper-middle” tier of managers deserves special attention. Rather than rewarding these managers with stock or options, the authors suggest use of a combination of uncapped but “held-at-risk” bonuses denominated in subordinated inside debt as the best way of rewarding effort and competence while controlling opportunities for risk-shifting.

This article looks at the future of futures studies (FS) over the next 20 years from a practitioner’s viewpoint. It begins with favorable developments for FS in the organizational context. The main body covers how FS can take advantage of these more favorable developments. It then anticipates some key methodological and professional challenges and how FS might meet them. It concludes with a few comments about the prospects for a self-actualized FS.The single biggest challenge for FS over the next generation from my practitioner’s point-of-view is to get beyond the cyclicality of interest in the future and get FS firmly integrated into the organizational context. Our experience to date convinces me that we have earned “the right to practice,” and we must now focus the next few decades on sinking roots “inside”. The good news is that there are several developments suggesting that this is not just a preferable but also a probable future. 相似文献

This paper assesses the impact of a certain structure of interbank exposures on the stability of a stylized financial system. Given a certain balance sheet structure of financial institutions, a large number of valid matrices of interbank exposures is created by a random generator. Assuming a certain loss given default, domino effects are simulated. The main results are, first, that financial stability depends not only on the completeness and interconnectedness of the network, but also on the distribution of interbank exposures within the system (measured by entropy). Second, looking at random graphs, the sign of the correlation between the degree of equality of the distribution of claims and financial stability depends on the connectivity of the financial system as well as on additional parameters that affect the vulnerability of the system to interbank contagion. Third, the more concentrated the assets are within a money center model, the less stable it is. Fourth, a money center model with asset concentration among core banks is less stable than a random graph with banks of homogeneous size. 相似文献

We re-examine the widely held belief that analysts?? earnings per share (EPS) forecasts are superior to random walk (RW) time-series forecasts. We investigate whether analysts?? annual EPS forecasts are superior, and if so, under what conditions. Simple RW EPS forecasts are more accurate than analysts?? forecasts over longer horizons, for smaller or younger firms, and when analysts forecast negative or large changes in EPS. We also compare the accuracy of a third forecast of longer-term earnings based on a na?ve extrapolation of analysts?? 1-year-ahead forecasts. Surprisingly, this na?ve extrapolation provides the most accurate estimate of long-term (2- and 3-year-ahead) earnings. These findings recharacterize prior generalizations about the superiority of analysts?? forecasts and suggest that they are incomplete, misleading, or both. Moreover, in certain settings, researchers can rely on forecasts other than these explicit forecasts. 相似文献
