Wage inequality and team production: An experimental analysis

Numerous survey studies report that human resource managers curb wage inequality with the intent to avoid detrimental effects on workers’ morale. However, there exists little controlled empirical evidence demonstrating that horizontal social comparisons and wage inequality have adverse effects on worker behavior. In this paper, we present data from a laboratory experiment that studies the impact of wage inequality on participation and effort choices in team production. Overall, we do not find evidence that wage inequality has a significant impact on either participation or effort choices.     

Elder abuse in nursing homes: an ecological perspective

Population trends suggest that the next 20 years will witness a dramatic increase in the adult population aged 65 and older. Projected increases in the elderly population are expected to significantly increase the stress on family and professional caretakers. Stress, in the context of caregiving relationships, is a risk factor associated with increased prevalence of elder abuse in familial and institutional settings. As increasing numbers of older adults are moved from family caregiving to nursing home care settings, it becomes important to identify the pattern of elder abuse risk factors in nursing home facilities. An ecological model is proposed for better understanding the risk factors associated with elder abuse in nursing homes and the complex interaction of individual/person characteristics and contextual factors in institutional elder abuse. An ecological perspective to institutional elder abuse provides a framework for guiding and informing future research on the risk factors of nursing home abuse and, in turn, for the development of effective interventions and relevant social policies.     

Gesundheitsförderliche Arbeitsgestaltung als Ansatzpunkt für das Recruiting in der Zeitarbeit

Temporary work agencies are constantly seeking new personnel. However, the industry’s image as well as reports on unfavourable working conditions impede the recruitment of new temporary agency workers (TAW). In the present study semi-structured interviews were conducted with 11 TAW to identify work characteristics that are perceived as potentially stressful and motivating, respectively. The results of the interview study can yield valuable hints for the improvement of the quality of work and further support the recruitment of new TAW. The results show that the working conditions of TAW contain a multitude of demands – e.g., high levels of insecurity, flexibility requirements and experiences of social marginalization – but only few resources. Starting from these insights possible measures are discussed that are suitable to improve TAW’s working conditions and provide recruiters with valuable arguments for the recruitment of new staff.

The Value of Environmental Information without Control of Subsequent Decisions

The standard value of information approach of decision analysis assumes that the individual or agency that collects the information is also in control of the subsequent decisions based on the information. We refer to this situation as the “value of information with control (VOI‐C).” This paradigm leads to powerful results, for example, that the value of information cannot be negative and that it is zero, when the information cannot change subsequent decisions. In many real world situations, however, the agency collecting the information is different from the one that makes the decision on the basis of that information. For example, an environmental research group may contemplate to fund a study that can affect an environmental policy decision that is made by a regulatory organization. In this two‐agency formulation, the information‐acquiring agency has to decide, whether an investment in research is worthwhile, while not being in control of the subsequent decision. We refer to this situation as “value of information without control (VOI‐NC).” In this article, we present a framework for the VOI‐NC and illustrate it with an example of a specific problem of determining the value of a research program on the health effects of power‐frequency electromagnetic fields. We first compare the VOI‐C approach with the VOI‐NC approach. We show that the VOI‐NC can be negative, but that with high‐quality research (low probabilities of errors of type I and II) it is positive. We also demonstrate, both in the example and in more general mathematical terms, that the VOI‐NC for environmental studies breaks down into a sum of the VOI‐NC due to the possible reduction of environmental impacts and the VOI‐NC due to the reduction of policy costs, with each component being positive for low environmental impacts and high‐quality research. Interesting results include that the environmental and cost components of the VOI‐NC move in opposite directions as a function of the probability of environmental impacts and that VOI‐NC can be positive, even though the probability of environmental impacts is zero or one.     

Exploring Reductions in London Underground Passenger Journeys Following the July 2005 Bombings

We examine the reduction in London Underground passenger journeys in response to the July 2005 bombings. Using entrance data for London Underground stations between 2001 and 2007, we incorporate demand and supply factors in a multivariate time‐series regression model to estimate changes in passenger journeys between different Underground lines. We find that passenger journeys fell by an average of 8.3% for the 4 months following the attacks. This amounts to an overall reduction of 22.5 million passenger journeys for that period. Passenger journeys returned to predicted levels during September 2005, yet we find evidence of reduced travel until June 2006. Our estimates controlled for other factors, including reduced Underground service provision due to damage from the attacks, economic conditions, and weather, yet substantial reductions in passenger journeys remained. Around 82% of passenger journey reductions following the 2005 attacks cannot be attributed to supply‐side factors or demand‐side factors such as economic conditions, weather, or the summer school‐break alone. We suggest that this reduction may partially be due to an increased perception of the risk of Underground travel after the attacks.     

Prospective Relations Between Adolescents' Social‐emotional Competencies and Their Friendships

Little is known about what factors predict the formation of reciprocal same‐sex friendships during early adolescence. To examine whether social‐emotional competencies aid in establishing and maintaining these friendships at the beginning and end of seventh grade, 380 German youth (mean age = 12.6 years; 49 percent boys; 100 percent White) reported on their peer support networks and on three broad categories of social‐emotional competencies (i.e., non‐constructive anger regulation, constructive anger regulation, emotional awareness, and expression disclosure). Regression analyses indicated the number of reciprocal friendships at Time 2 (T2) was predicted by adolescents' constructive anger regulation through redirection of attention, and social support when angry at the friend, even after controlling for Time 1 number of friends and peer acceptance. Among girls, willingness to self‐disclose marginally predicted their number of reciprocal friends at T2. Results are discussed in terms of the specific social‐emotional competencies that facilitate involvement in reciprocal friendships.
