(Un)Ethical Behavior and Performance Appraisal: The Role of Affect,Support, and Organizational Justice

Performance appraisals are widely used as an HR instrument. This study among 332 police officers examines the effects of performance appraisals from a behavioral ethics perspective. A mediation model relating justice perceptions of police officers’ last performance appraisal to their work affect, perceived supervisor and organizational support and, in turn, their ethical (pro-organizational proactive) and unethical (counterproductive) work behavior was tested empirically. The relationship between justice perceptions and both, ethical and unethical behavior was mediated by perceived support and work affect. Hence, a singular yearly performance appraisal was linked to both ethical and unethical behaviors at work. The finding that ethical and unethical aspects of employee behavior share several of the same organizational antecedents, namely organizational justice perceptions, has strong practical implications which are discussed as well.     

Naturally designed for masculinity vs. femininity? Prenatal testosterone predicts male consumers' choices of gender-imaged products

In this paper, we find that a proxy of prenatal testosterone exposure (i.e., digit ratio) is a significant predictor of preferences for products that differ in perceived masculinity vs. femininity. A more masculine (feminine) digit ratio predicts choice of products that have an increasingly masculine (feminine) image. This relationship is statistically significant for male consumers, but not for females.

Abstract

The sustained reduction in mortality rates and its systematic underestimation has been attracting the significant interest of researchers in recent times because of its potential impact on population size and structure, social security systems, and (from an actuarial perspective) the life insurance and pensions industry worldwide. Despite the number of papers published in recent years, a comprehensive review has not yet been developed.

This paper attempts to be the starting point for that review, highlighting the importance of recently published research—most of the references cited span the last 10 years—and covering the main methodologies that have been applied to the projection of mortality rates in the United Kingdom and the United States. A comparative review of techniques used in official population projections, actuarial applications, and the most influential scientific approaches is provided. In the course of the review an attempt is made to identify common themes and similarities in methods and results.

In both official projections and actuarial applications there is some evidence of systematic overestimation of mortality rates. Models developed by academic researchers seem to reveal a trade-off between the plausibility of the projected age pattern and the ease of measuring the uncertainty involved. The Lee-Carter model is one approach that appears to solve this apparent dilemma.

There is a broad consensus across the resulting projections: (1) an approximately log-linear relationship between mortality rates and time, (2) decreasing improvements according to age, and (3) an increasing trend in the relative rate of mortality change over age. In addition, evidence suggests that excessive reliance on expert opinion—present to some extent in all methods—has led to systematic underestimation of mortality improvements.     

Freia and Kompas,The Central Planning Bureau's new generation of macro-economic policy models: A review article

Summary On the eve of the 50th anniversary of macro-economic model building in the Netherlands, the Central Planning Bureau introduced two new models for policy analysis, the annual model FREIA and the quarterly model KOMPAS. The main novelty of these models as compared to their predecessors is a fully fledged submodel of the financial sector. This review article highlights some features of both models and compares their properties with those of other models and with results from the literature. The models have been explicitly constructed for practical use and therefore do not reflect any theoretical approach in particular.Critical comments on a previous version of this article by the Department's colleagues and a referee are gratefully acknowledged.
