Rebates, inventories, and intertemporal price discrimination

We demonstrate that universally redeemed rebates can increase manufacturer profits by reducing the incentives of downstream retailers to hoard inventories when optimal wholesale prices vary predictably over time. By bypassing retailers and making direct contracts with buyers, the manufacturer can increase the variations in effective prices paid by consumers without concomitantly creating larger incentives for retailers to hold inventories. During profitable, high-demand periods, manufacturer revenues are ordinarily constrained by'competition'from retailer inventories, thus limiting profits. However, by selectively offering rebates to consumers while maintaining high wholesale prices, low-demand periods can be accommodated without inducing retailer hoarding.     

Health benefits of volunteering in the Wisconsin longitudinal study

We investigate positive effects of volunteering on psychological well-being and self-reported health using all four waves of the Wisconsin Longitudinal Study. Confirming previous research, volunteering was positively related to both outcome variables. Both consistency of volunteering over time and diversity of participation are significantly related to well-being and self-reported health. The relationship of volunteering to psychological well-being was moderated by level of social integration, such that those who were less well integrated benefited the most. Mattering appears to mediate the link between volunteering and wellbeing. Controls for other forms of social participation and for the predictors of volunteering are employed in analyses of well-being in 1992. We find volunteering effects on psychological well-being in 2004, controlling for 1992 wellbeing, thus providing strong evidence for a causal effect.     

Reliant behavior in the United States and Japan

Japanese economic success is often attributed to culturally reinforced psychological conditioning that promotes interpersonal reliance, cooperation, and a group interest orientation. This article provides direct experimental evidence on differences in behavior among future business people in the United States and Japan. Utilizing a simple, two person extensive form game of perfect information introduced by Selten (1975), we provide evidence that, contrary to some views, the Japanese can be less reliant on the behavior of others and are more likely to take actions at variance with group welfare in some settings. Thus, popular explanations of Japanese economic achievements may require further exploration.     

Accessing a hard to reach population: reflections on research with young carers in Ireland

In keeping with developments in children's rights, research is increasingly including the views of children. Accessing a hard to reach population of children can, however, raise significant ethical and methodological challenges for researchers. Negotiating access through gatekeepers, securing parental consent and limits on confidentiality are central issues in the recruitment process of children. This paper is based on a qualitative study of young carers in the Irish population. It outlines the methodological approaches employed to access a representative sample of young carers and the measures taken to fulfil ethical obligations. In the recruitment phase of the study, researchers attempted to strike a balance between two sometimes competing requirements, the need to protect children from harm and to respect children's competence. This paper reflects on the success and limitations of the approaches adopted towards achieving this balance, exploring the use of gatekeepers as a method to identify and recruit a hidden population, and revisiting the measures taken to comply with the ethical requirements of parental consent and limits on confidentiality.     

Nonverbal Decoding on Facebook: Applying the IPT-15 and the SSI to Personality Judgments

This study uses the lens model paradigm to explore whether two interpersonal sensitivity tests [i.e., Interpersonal Perception Task (IPT-15), Social Skills Inventory (SSI)] are associated with the accuracy of personality judgments made from Facebook (FB) profile pages. Target participants’ (N = 100) personality, self-monitoring, and FB honesty were self-reported, and the FB profile of each target was downloaded. Observers (N = 35) completed the IPT-15 and SSI and then estimated each profile owner’s personality from the profile pages. Observers’ scores on the IPT-15 were positively associated with the accuracy of estimates of targets’ extraversion and neuroticism. Observers’ SSI-ES scores were positively associated with the accuracy of estimates of targets’ agreeableness, conscientiousness, and openness. Characteristics of targets, such as self-monitoring, FB honesty, and overall FB use, also affected the accuracy of estimates. Results demonstrate that offline measures of sensitivity are associated with the accuracy of online personality judgments.
