Top Management Team Diversity: A Review of Theories and Methodologies

This paper reviews empirical research on top management team (TMT) diversity. A number of scholars have concluded that upper echelons findings, in particular in terms of the consequences of TMT heterogeneity, have been inconclusive. This review conducts an in‐depth analysis of conceptual and methodological issues related to upper echelons diversity studies and offers some directions for future research. Sixty journal articles, published in ten top international journals over a 22‐year period (1984–2005), were analyzed. The results suggest that upper echelons research is increasingly multidisciplinary in nature; however, in‐depth inquiries into the antecedents of TMT composition and the multilevel contextual influences on the implications of TMT heterogeneity are still needed. This review finds that clarity about level of analysis, both theoretically and empirically, remains an important issue in the field and thus a multilevel approach is strongly encouraged. Moreover, the complexity of diversity as a theoretical construct needs to be acknowledged and operationalized accordingly in upper echelons studies.     

Russian perspectives on elder abuse: an exploratory study

The purpose of this exploratory study was to analyze Russian perceptions of elder abuse as reflected in their examples of abusive behavior from an adult child to an aging parent. Also of interest was the possibility of gender differences in the Russian perspectives on elder abuse. The convenience sample consisted of 21 Russian participants (10 males, 10 females, and one without gender identified), who provided examples of extreme, moderate, and mild abuse from an adult child towards an aging parent. Most examples of extreme abuse were forms of physical violence. Typical examples of moderate abuse were instances of psychological aggression-particularly verbal aggression-and neglect. The most common examples of mild abuse were verbal aggression and neglect. One-way analyses of variance revealed statistically significant gender differences in the number of references to psychological aggression in general and to verbal aggression in particular in the examples of moderate abuse, with females giving more examples than males.     

Marriage migration: just another case of positive assortative matching?

It is a stylized fact that marriage formation involves positive assortative matching on education. We also find this in the case of immigrants, even when they tend to “import” their spouses and potentially trade off education for other favorable characteristics. For Pakistanis, we find positive compensating differentials in terms of high education to youth having adopted host country norms, when marrying a marriage migrant. This indicates that Pakistani marriage migrants pay a premium to be able to marry and live in Denmark. For Turks, individuals having source country norms pay a premium in order to import a partner, indicating that unspoiled traditional norms are traded off for education.

Kernel density estimation for heavy-tailed distributions using the champernowne transformation

When estimating loss distributions in insurance, large and small losses are usually split because it is difficult to find a simple parametric model that fits all claim sizes. This approach involves determining the threshold level between large and small losses. In this article, a unified approach to the estimation of loss distributions is presented. We propose an estimator obtained by transforming the data set with a modification of the Champernowne cdf and then estimating the density of the transformed data by use of the classical kernel density estimator. We investigate the asymptotic bias and variance of the proposed estimator. In a simulation study, the proposed method shows a good performance. We also present two applications dealing with claims costs in insurance.     

The Use of Telematics Devices to Improve Automobile Insurance Rates

Most automobile insurance databases contain a large number of policyholders with zero claims. This high frequency of zeros may reflect the fact that some insureds make little use of their vehicle, or that they do not wish to make a claim for small accidents in order to avoid an increase in their premium, but it might also be because of good driving. We analyze information on exposure to risk and driving habits using telematics data from a pay‐as‐you‐drive sample of insureds. We include distance traveled per year as part of an offset in a zero‐inflated Poisson model to predict the excess of zeros. We show the existence of a learning effect for large values of distance traveled, so that longer driving should result in higher premiums, but there should be a discount for drivers who accumulate longer distances over time due to the increased proportion of zero claims. We confirm that speed limit violations and driving in urban areas increase the expected number of accident claims. We discuss how telematics information can be used to design better insurance and to improve traffic safety.

Did Australia’s Baby Bonus Increase Fertility Intentions and Births?

In May 2004, the Australian government announced a “Baby Bonus” policy, paying women an initial A$3,000 per new child. We use household panel data from the Household, Income and Labour Dynamics in Australia Survey (N = 14,932) and a simultaneous equations approach to analyze the effects of this bonus on fertility intentions and ultimately births. The results indicate that opportunity costs influence intentions and births in predictable ways. Fertility intentions rose after the announcement of the Baby Bonus, and the birth rate is estimated to have risen modestly as a result. The marginal cost to the government for an additional birth is estimated to be at least A$3,000 per new child. We use household panel data from the Household, Income and Labour Dynamics in Australia Survey (N = 14,932) and a simultaneous equations approach to analyze the effects of this bonus on fertility intentions and ultimately births. The results indicate that opportunity costs influence intentions and births in predictable ways. Fertility intentions rose after the announcement of the Baby Bonus, and the birth rate is estimated to have risen modestly as a result. The marginal cost to the government for an additional birth is estimated to be at least A126,000.     

Pop Goes the Woozle: Being Misled by Research on Child Custody and Parenting Plans

Mental health professionals, lawyers, and judges whose work involves child custody decisions are often presented with social science research on issues related to which parenting plan is in the children’s best interests. Unfortunately, this research can be misrepresented in ways that mislead these professionals and the children’s parents, leading to child custody decisions that are not the most beneficial for the children. The process of misrepresenting the research in ways that create myths and misconceptions has been referred to as woozling. This article describes how social science data can be woozled, illustrating this with examples related to parenting plans for children under the age of 5 whose parents have separated.     

Shared Parenting After Divorce: A Review of Shared Residential Parenting Research

One of the most complex and compelling issues confronting policymakers, parents, and the family court system is what type of parenting plan is most beneficial for children after their parents' divorce. How much time should children live with each parent? An increasing number of children are living with each parent at least 35% of the time in shared residential parenting families: How are these children and their parents faring? In what ways, if any, do divorced parents who share the residential parenting differ from parents whose children live almost exclusively with their mother? How stable are shared residential parenting plans? By reviewing the existing studies on shared parenting families, these questions are addressed.
