Over the years, cognitive biases have been examined throughout the decision-making literature, but little work has investigated the cognitive biases operating in ethical decision making. The present effort explores a taxonomy of biases through interviews with university faculty members. Additionally, this study identifies the psychological processes giving rise to these biases in ethical decision making. Results suggest that the biases listed in the taxonomy are indeed operating in the ethical decision making of university faculty. Implications of these results are discussed. 相似文献

Abstract The article analyses the impact of various types of reform options on social security pension system financial sustainability and on a range of macroeconomic variables. The HERPOR model is used to consider the likely effects of parametric reforms of the existing pay-as-you-go system, as well as those of a systemic reform. The article concludes that the former are sufficient to ensure financial sustainability, although they should be accompanied by employment implementation measures. The article concludes that a fully pre-funded system does not seem to be a viable option for policy-makers in the redesigning of social security pension systems, due to the high transition costs involved. 相似文献

This article analyses the impact of replacement migration on the financial sustainability of the old‐age pension system in Portugal, a country with one of the largest ageing populations in Europe. We do this using demographic forecasts and prospective exercises for the evolution of the Portuguese economy. During the 2015–2060 period, our results evidence the positive impacts of international migration on old‐age pension system financial balances, reaching over 3 per cent of GDP after 2045. Moreover, even when taking into considering the low dynamics for the Portuguese economy, replacement migration is an important input to improve pension system financial sustainability. 相似文献

Training is a costly investment. As such, it is of great interest to know the extent to which that investment is yielding a positive return. Recent meta-analytic efforts have observed that ethics training programs are, indeed, having a positive effect, leading to the conclusion that the programs are working. However, they have also uncovered considerable variability in the effectiveness of ethics training programs, which leads to the purpose of the present study—to review current practices in ethics training evaluation. Through this review of 243 studies, consisting of 380 ethics trainings, we identified major themes in evaluation practices and training design. The tradeoffs associated with these evaluation procedures and designs are discussed, along with directions for future research. 相似文献

In this article, we propose a class of logarithmic autoregressive conditional duration (ACD)-type models that accommodates overdispersion, intermittent dynamics, multiple regimes, and asymmetries in financial durations. In particular, our functional coefficient logarithmic autoregressive conditional duration (FC-LACD) model relies on a smooth-transition autoregressive specification. The motivation lies on the fact that the latter yields a universal approximation if one lets the number of regimes grows without bound. After establishing sufficient conditions for strict stationarity, we address model identifiability as well as the asymptotic properties of the quasi-maximum likelihood (QML) estimator for the FC-LACD model with a fixed number of regimes. In addition, we also discuss how to consistently estimate a semiparametric variant of the FC-LACD model that takes the number of regimes to infinity. An empirical illustration indicates that our functional coefficient model is flexible enough to model IBM price durations. 相似文献

Ethical codes of conduct exist in almost every profession. Field-specific codes of conduct have been around for decades, each articulating specific ethical and professional guidelines. However, there has been little empirical research on researchers’ perceptions of these codes of conduct. In the present study, we interviewed faculty members in six research disciplines and identified five themes bearing on the circumstances under which they use ethical guidelines and the underlying reasons for not adhering to such guidelines. We then identify problems with the manner in which codes of conduct in academia are constructed and offer solutions for overcoming these problems. 相似文献

Realized Volatility: A Review 总被引:1,自引:1,他引:0
This article reviews the exciting and rapidly expanding literature on realized volatility. After presenting a general univariate framework for estimating realized volatilities, a simple discrete time model is presented in order to motivate the main results. A continuous time specification provides the theoretical foundation for the main results in this literature. Cases with and without microstructure noise are considered, and it is shown how microstructure noise can cause severe problems in terms of consistent estimation of the daily realized volatility. Independent and dependent noise processes are examined. The most important methods for providing consistent estimators are presented, and a critical exposition of different techniques is given. The finite sample properties are discussed in comparison with their asymptotic properties. A multivariate model is presented to discuss estimation of the realized covariances. Various issues relating to modelling and forecasting realized volatilities are considered. The main empirical findings using univariate and multivariate methods are summarized. 相似文献

This article is the result of an Ergonomic Diagnosis in a study for a Specialization Course in Ergonomics. The research is being done in a public hospital in the city of Rio de Janeiro, where the target system is the radiology sector. For diagnosis purposes, subjective techniques were used, such as an open-ended survey, Corlett questionnaire and techniques for evaluating ergonomic risk such as Owas and Rula. Systematic observation was emphasized using photos and films. Preliminary observations made to the radiographers found that these professionals suffer risks of physical and verbal harassment, as well as sexual harassment. Most of them feel discriminated against in terms of race and accumulate activities demanding a lot of attention, as the medical diagnosis and subsequent procedures will depend on the outcome of this task. They accumulate tension due to the weight of responsibility, since there are cases where the patient has risk of death. 相似文献

To deal with the problem of underestimation of top incomes in household surveys, we propose a methodology to combine the income distributions of the Brazilian 2010 Census (survey) and of 2010 DIRPF (personal income tax reports). The method consists in estimating a system of non-response weights that uses as frame the tax register and is applied to the top of the distribution. After applying this calibration methodology, we decompose inequality income sources. Correcting survey distributions with tax data increases the contribution of non-labor income to inequality, as the case of the Brazilian Census shows. Changes in the methodology do not affect the results substantially. 相似文献

Gambling is currently widespread across the globe and despite legally restricted, it is significantly common in Brazil. A traditional and common form of gambling in Brazil is the Brazilian animal game (BAG)—“Jogo do bicho” in Portuguese. In 2013, BAG activities collected approximately 19 billion Brazilian reais—equivalent to more than 8 billon American dollars, a figure almost 60 % higher than legal lotteries. Although a common form of gambling, the gambling behavior and psychopathology of gambling disorder (GD) associated with BAG has never been systematically studied. The aim of this study is to conduct, the first research approaching GD due to BAG. We assessed 897 participants of whom 63 subjects (7.0 %) presented with GD due to BAG and 834 with GD associated with other forms of gambling. After comparing these two groups, major differences were found in demographics, gambling behavior elements and psychopathological variables. This research reinforces the need for further research on BAG and the need for specific approaches in GD. The particularities of BAG may affect treatment strategies as, for example, suggest some adaptations in social and psychotherapeutic approaches. We also highlight the need to acknowledge the “hidden” BAG as a potential addictive game. 相似文献
