A fundamental statistical problem is to indicate which of two hypotheses is better supported by the data. Statistics designed
for this purpose are called weight of evidence. In this paper we study the problem of robust weights of evidence, optimal
in their performance while robust in the infinitesimal sense of the influence function. 相似文献

Managers confronted with evidence of employee misconduct were biased in their recommendations for disciplinary action depending on whether they liked or disliked the accused employee. As expected, when evidence was strong, managers more frequently recommended that the subordinate receive assistance-focused and punishment-focused disciplinary action than when evidence was weak. When managers indicated they liked the employee, they were not inclined to suggest use of disciplinary actions but endorsed use of discipline when they disliked the accused employee. Joint effects of evidence and liking were found for assistance-focused and punishment-focused actions. Implications and the relevance of the biasing effects of managers' recommended actions are discussed. 相似文献

The paper focuses on how the traditional textbook approach to econometrics, by conflating statistical and substantive information, has contributed significantly to the mountains of untrustworthy evidence accumulated over the last century. In a nutshell, the problem is that when one's favorite theory is foisted on the data, the end result is invariably an empirical model which is both statistically and substantively misspecified, but one has no way to disentangle the two sources of error in order to draw reliable inferences. It is argued that ignoring statistical misspecification, and focusing exclusively on the evaluation of the statistical results – taken at face value – on substantive grounds, has proved a disastrous strategy for learning from data. Moreover, the traditional textbook stratagems of error-fixing designed to alleviate statistical misspecification often make matters worse. Instead, the paper proposes a number of strategies that separate the statistical and substantive sources of information, ab initio, and address the problem by replacing goodness-of-fit with statistical adequacy to secure the statistical reliability of inference, and then proceed to pose questions of substantive adequacy. 相似文献

Whilst there is growing recognition across the non-profit literature, that the giving of resources ought to be informed by rigorous evidence, few studies to date have examined how high and ultra-high-net-worth donors use evidence to inform their philanthropy, the type and quality of the evidence they utilise, and how they measure the performance of the charities they support. The primary objective of this study was to examine whether and how philanthropists employ evidence to inform their decision-making. We employed in-depth qualitative research methods to elicit the perspectives of philanthropists on how they engaged with evidence and, in so doing, filled a gap in the data. We found barriers to utilising evidence included challenges in accessing evidence, difficulties in assessing the quality and appropriateness of evidence and insufficient resources to capture evidence. Facilitators of evidence use included: making evidence more accessible and enhanced access to professional philanthropy advice and advisors. Despite growing awareness of the importance of evidence, few donors employed sound evidence-based models of philanthropy. 相似文献

Administrative data on monthly wages in Iceland during 1998–2010 provide new insight into nominal wage rigidity. Unlike the data used in previous work, ours have a higher frequency, minimal measurement error, and a long sample including a period of substantial macroeconomic instability. We find that the monthly frequency of nominal wage changes is 13 percent. Although nominal wage cuts are rare, their frequency rises following a large macroeconomic shock. Timing of wage changes is both time-dependent and state-dependent: we find evidence of synchronization of adjustment and contracts of fixed duration, but also that inflation and unemployment over the wage spell affect the timing of adjustment. 相似文献

In this paper we provide evidence on the budgetary practice of 135 large firms located in Spain. The results have allowed us to evaluate a wide range of weakness attributed to the traditional budgeting approach, still called into question, as well as to discern towards what emerging paradigm budget is aligned the practice analyzed. Evidence shows that the budgetary approach used by the firms have managed to resolve many of the weakness imputed to the traditional budgeting. At the same time, we note that in the most of the cases studied these procedures are in line with the conceptual ideas defended by the Better Budgeting. 相似文献
