Credit underwriting is a dynamic process involving multiple interactions between borrower and lender. During this process, lenders have the opportunity to obtain hard and soft information from the borrower. We analyze more than 108,000 home equity loans and lines‐of‐credit applications to study the role of soft and hard information during underwriting. Our data set allows us to distinguish lender actions that are based strictly on hard information from decisions that involve the collection of soft information. Our analysis confirms the importance of soft information and suggests that its use can be effective in reducing overall portfolio credit losses ex post. 相似文献

The ultimate challenge with which we are presented in connection with social investing is no more and no less than this: enhancing the function of conscience in the modern global business corporation. As with individual conscience, however, corporate conscience can be influenced in two ways: from the inside and from the outside. Investment decisions provide external influences, while management values provide influence from the inside. 相似文献

针对最小值控制递归平均(Minima Controlled Recursive Averaging,MCRA)算法不能快速跟踪突变噪声的问题,提出了一种基于频谱排序和筛选的突变噪声快速估计方法。该方法在MCRA算法的基础上对带噪语音的功率谱进行排序,筛选出不含语音信号的频点来估计噪声的平均功率谱;当检测到噪声突变时,对当前的平滑参数和状态变量进行校正。仿真结果表明,该方法可以将突变噪声的跟踪时间缩短90%以上;用于语音降噪处理时,音质可以提升约0.4分。该方法具有一定的工程应用价值。 相似文献

Should we screen the population routinely for the presence of breast or prostatic cancer? This simple proposition masks a landscape of complexities, including the economics of screening, the prevalence and probability of the disease, desired frequencies of intervention and a willingness to adopt preventive screening. These ‘risk factors’ form part of a broader landscape of uncertainty that characterises the intricacies of clinical decision-making. Deepening our understanding of the way in which clinicians evaluate risk and uncertainty requires a framing of insights into language, communication, psychology and epistemology. This paper explores perspectives in forecasting and uncertainty as a basis for understanding individuals’ perceptions of risk when assessing their options in both preventative and curative medicine. At the heart of the issue is the prevalence of diagnostic error; this paper argues for the use of systematised approaches to medical error management and inclusive approaches to research in the field. The advantages of augmenting the management of unforeseen consequences through an improved understanding of the issues that are of concern to patients, carers, and medical practitioners alike forms a key construct in this paper. We conclude with an exploration of potential opportunities for improvements in medical practice: changes that may reduce the disbenefits of uncertainty and enhance the management of the general risks associated with clinical decision-making. 相似文献
