Key risks and threats of the long-term development of the Russian economy, originating from the social sphere, are revealed and analyzed. The article focuses on human capital development and replenishment problems, as well as on the social effects of these problems on education, health conditions, labor migration, and pension provision.  相似文献

Prior research indicates that analysts do not fully adjust for the general downward bias in earnings guidance issued by management. We report the results of two experiments designed to investigate how guidance track record and analysts’ incentives jointly explain the extent to which analysts adjust for guidance bias. Our results suggest that analysts with accuracy incentives adjust for management’s track record of downwardly biased guidance when the bias is relatively small (one cent), but those with relationship incentives do not. Furthermore, the difference in adjustment is larger when the bias track record is inconsistent than when it is consistent. Also, when guidance bias is larger (two cents) relative to smaller (one cent), analysts with relationship incentives partially adjust, as they appear to strike a balance between accuracy and their desire to please management. These findings hold implications for investors, regulators, and the interpretation of prior research.  相似文献

Transparency research related to the regulatory process would benefit most from two types of empirical studies. One batch of studies, described in the fifth section of this essay, would focus on the American states and the member states of the European Union to identify the factors that determine whether regulatory processes are more transparent and whether transparency is successful in improving regulations and the regulatory process. In other words, we need comparative state (for the US) and member state (for the EU) studies to develop metrics for the quality of regulations and the role of transparency is advancing or weakening the quality of regulations at the state (for the US) and member state (for the EU) level. The second batch of studies, described in the sixth section of this essay, would explore who uses the information currently provided at the levels of transparency currently available in regulatory processes at the European Union and federal government of the United States. Who benefits from transparency and how are they using the available transparency mechanisms?  相似文献

The events triggered by the Global Financial Crisis (GFC) have led to calls for the regulation of financial markets. Given that regulation may involve opportunity costs, this paper examines whether tighter futures price limits can reduce the effectiveness of a futures hedge. We propose a new model that uncovers the underlying spot-futures dynamics when futures prices are subject to limits. We use the model to determine the maximum number of limit days that can occur before minimum variance hedging outcomes are adversely affected. Application of this model to the US soybean and corn markets reveals that existing limits do not reduce hedge effectiveness. If the frequency of limit days increases from current levels of 1% to approximately 3–4%, conventional hedging approaches will experience economically and statistically significant increases in portfolio variance. These results are important for hedgers, clearing houses and regulators in light of the recent calls for derivatives regulation.  相似文献

The last-mile problem presents a daunting challenge for many logistics service providers, especially some 7000 small, localized operations for whom the cost of complex software solutions is often prohibitive. As a result, last-mile dispatchers rely on simple heuristics to ensure adequate customer service at an acceptable cost. This research effort extends prior qualitative work by developing and testing a simple vehicle routing heuristic, based on behaviors observed in practice, that prioritizes customer service over cost against other simple vehicle routing heuristics across a variety of environments using simulation. The results support the inclusion of a customer service focus in vehicle routing and the addition of such heuristics to existing algorithm portfolios, specifically in urban areas with well-developed highway systems.  相似文献
