We document asymmetric announcement effects of consumer sentiment news on United States stock and stock futures markets. While a negative market effect occurs upon the release of bad sentiment news, there is no market reaction for the counterpart good news. This supports the “negativity effect” hypothesis. Notably, this effect seems most likely to occur in salient stocks, which is consistent with the availability heuristic.  相似文献

It is claimed that the concept of ‘sustainable economic development’ is central to the new ‘practical’ environmentalism of the 1980s. Intuitively, sustainability perspectives seem to suggest that knowledge accumulated in the natural sciences ought to be applied to economic processes. They contain the proposition that there is a real prospect that increasing per capita real incomes over time can be achieved in an environmentally benign manner, or at least without posing severe environmental risks. A working definition of sustainable development might be as follows: Sustainable development involves maximising the net benefits of economic development, subject to maintaining the services and quality of natural resources over time. Economic development is broadly construed to include not just increases in real per capita incomes but also other elements in social welfare. Development will necessarily involve structural change within the economy and in society. Maintaining the services and quality of the stock of resources over time implies, as far as practicable, acceptance of the following rules: utilise renewable resources at rates less than, or equal to, the natural or managed rate at which they can regenerate; optimise the efficiency with which non-renewable resources are used in the long run, subject to substitutability between resources, and technological progress.  相似文献

This note provides an empirical analysis of the potential for heuristic-based approaches to derive a divisional cost of equity from a firm's total cost of capital. Since an empirical relationship between fundamental information and systematic risk has previously been shown in other studies, idiosyncratic information on risk and performance ought to serve as a good proxy to calculate divisional adjustments. Two practically used, heuristic-based approaches are tested and a significant relationship is found between one of the measures and CAPM beta. This method may offer a plausible and comparatively uncomplicated method for adjusting a firm's total cost of capital for divisional use.  相似文献

High-quality science communication to the public depends to a large extent on the way research findings are translated into comprehensible language and common speech. In this communicative process, a reasonable evaluation of the trustworthiness of empirical findings, based on an adequate interpretation of statistical analyses, is absolutely crucial. This paper’s authors argue that the credibility of science is jeopardised by two compromising developments within science itself: on the one hand, an inflation of ostensible empirical evidence related to misuses and misinterpretations of the concept of statistical significance, and, on the other, a sensationalist overvaluation of the results of single studies instead of an adequate representation of the available body of evidence in a given scientific field.  相似文献

Since the outbreak of the financial and economic crisis, confidence in politicians as well as the economists in their advisory expert panels seems to be at an all-time low. Why do politicians reject science-based advice unless it fits into their political agenda? Are economists misunderstood by politicians and vice versa? The tension between the ideal of evidence-based policy-making and the reality of policy-based evidence-making is hardly a new phenomenon. Therefore, the expectation that Donald Trump, the Brexiteers and European populists will necessarily disappoint their voters because they simply cannot deliver what they have promised is misleading. Experts would be well advised to use the debate on the post-factual era as an impetus to reflect critically on their profession. One opinion expressed in this Zeitgespräch is that the contested societal and political impact of modern economics is due to its restricted scientific self-concept. A more open, pluralistic and transdisciplinary self-definition of economics would strengthen its societal influence. Another contributor ponders the proper incentives to persuade academic economists to provide economic policy advice. Key is the independence of advisory institutions like the German Council of Economic Experts. The selection of people with the best scientific qualifications will ensure the reputation of such institutions.  相似文献

We investigate when organizational justice matters to employees’ commitment in the postacquisition process after a company is taken over in a cross‐border acquisition. Overwhelming evidence from the literature suggests that employees who are treated fairly during acquisitions are more committed to their new firms. We extend this finding by dividing organizational justice into three subdimensions: informational justice, interpersonal justice, and procedural justice. We find evidence that procedural justice is an important antecedent of affective merger commitment at an early stage of the integration period, while informational justice becomes important at a later stage. Further analysis on heterogeneity between the target firm's employees and the bidder firm's employees reveals that, immediately after the acquisition, target firm's employees value knowing where they will be at the new firm (procedural justice), while bidder firm employees are more concerned about communication and transparency (informational justice). Our results point to the importance of organizational justice in a cross‐border merger and acquisition (M&A) setting and the need for a separate study of issues related to bidder firms and target firms. © 2016 Wiley Periodicals, Inc.  相似文献

Since 2002, the Institute for Peace Promotion and Injury/Violence Prevention (CISALVA) at the Universidad del Valle, Cali, Colombia and the Colombia Program at Georgetown University have developed and implemented 21 epidemiologically based municipal crime observatories in intermediate-sized municipalities in Colombia. These crime observatories serve as monitoring centres that provide low cost, geo-referenced methods of data collection and analysis, which allow cities to develop more responsive policies and prevention programmes and enhance governance. This article focuses on the methodology employed and lessons learned that may be applicable to similar settings. Worth noting within the results was a significant decrease in homicides after the first year of the programme. Whether or not such results could be attributed to the method or to the nature of the interventions and policy initiatives stemming from it remains open to conjecture.  相似文献
