Abstract: The authors discuss the hiring patterns of some insurers and examine why insurers do not always seek out students with risk management and insurance backgrounds. The authors suggest that it is important for universities and insurers to work more closely so that students coming out of college insurance programs are well prepared to work in the insurance industry. 相似文献

Given the rising emphasis on environmental disclosures and the expressed importance of ‘good’ governance in determining the extent of information disclosure in general, we examine the relation between specific aspects of governance and media coverage and the quality of voluntary environmental disclosure (VED). Using a sample of 127 firms over a 6-year period (2000–2005), we empirically test characteristics of governance and media in relation to VED. Our results suggest that VED quality is positively associated with environmental media coverage, negative environmental media and board attributes of independence, diversity, and expertise. Results from supplemental analysis suggest that institutional investors exert influence over managerial decisions on environmental reporting only in the face of negative environmental media. Additionally, results from longitudinal analyses indicate that the quality of environmental disclosures increases over time. Our conclusion discusses the implications of these findings. 相似文献

Urban containment policies, including urban growth boundaries (UGBs), are a common tool used by city planners to promote compact development. We analyze how well UGBs do in containing development using fine-scale GIS data on cities in Oregon. Earlier studies on UGBs yield mixed results, with some authors finding no effects of UGBs on housing market variables and urbanization rates and others finding significant effects. A challenge in measuring these effects is that the location of the UGB is unlikely to be an exogenous determinant of a land parcel's value for development. The panel structure of our dataset allows us to estimate the UGB's effect on the probability of development using a difference-in-difference estimator applied to a narrow band of plots along each city's UGB. This estimator controls for time-invariant unobservable variables and common temporal effects among plots, thereby mitigating the potential for biased estimates due to the endogeneity of the UGB's location. We also pursue a novel approach to controlling for time-varying factors that exploits our fine-scale data. We find that UGBs contain development in many of the Oregon cities we examine, although there are some cities in which development rates are the same inside and outside of the UGB. Our results reveal that, in most cities, the effect of the UGB is small relative to pre-existing differences in development probabilities. This suggests that it may be difficult to identify UGB effects with cross-sectional data, the approach commonly taken in previous studies. 相似文献

The Renewal Energies Act has so far been one of the cornerstones of the energy revolution. As a result of the Act the production of electricity from renewable sources has been considerably increased. As the most expensive forms of renewable energies have grown fastest, average costs have not shrunk but have risen significantly. The ongoing growth led to increasing subsidies for renewable energies and growing costs for electricity consumers in business and private households. It would be insufficient to look at absolute cost developments only, as distribution effects may be critical. As electricity consumption only slightly depends on household income, higher income leads to lower significance of electricity costs. Therefore, low income households bear a relatively higher burden of costs for renewable energies. Furthermore, wealthy households could benefit from the subsidies as they can invest in renewable energy systems. 相似文献

Technology choice under changing peanut policies 总被引:2,自引:0,他引:2
The effect of marketing quotas and price supports on technology adoption are examined for peanut production in the southeastern United States using a real options model of investment with output price and yield uncertainty. The optimal choice of peanut production technology (dryland versus irrigated) in the southeast is shown to depend on price supports and how they change. The manner in which price supports change will have an effect on the choice and rates of abandonment or adoption of production technologies. 相似文献

At the inception of the internal market in health care GP fundholding was seen rather as a 'sidesho' to the main reforms. But as the reforms have worked through, GP fundholding has emerged as pivotal to the purchaserlprovider agenda and the changes now associated with GP fundholding will be major issues in directing future health care policy initiatives. Drawing on empirical data from three Scottish regions, this paper argues that fundholding is now significant because GPs perceive benefits for primary health care. The paper uses the data collected from the case studies in the regions to assess these gains on two levels: the 'micro' impact of fundholding on primary health care processes and the 'macro' issues raised for health care policy by involving GPs more closely in resource management. Some GPs wish to use resource management as a vehicle for enhancing equity within the NHS, others are more concerned to manage resources so as to expand their practices into sites which combine primary, secondary and community health care, still others envisage developing the market to include monetary rewards for 'efficient' practices. 相似文献

When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment. 相似文献

We compare and contrast time series momentum (TSMOM) and moving average (MA) trading rules so as to better understand the sources of their profitability. These rules are closely related; however, there are important differences. TSMOM signals occur at points that coincide with a MA direction change, whereas MA buy (sell) signals only require price to move above (below) a MA. Our empirical results show MA rules frequently give earlier signals leading to meaningful return gains. Both rules perform best outside of large stock series which may explain the puzzle of their popularity with investors, yet lack of supportive evidence in academic studies. 相似文献
