Adolescents' body‐tanning behaviours: influences of gender,body mass index,sociocultural attitudes towards appearance and body satisfaction

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.     

The Determinants of Green Product Development Performance: Green Dynamic Capabilities, Green Transformational Leadership, and Green Creativity

Because no previous literature discusses the determinants of green product development performance, this study develops an original framework to fill the research gap. This study explores the influences of green dynamic capabilities and green transformational leadership on green product development performance and investigates the mediation role of green creativity. The results demonstrate that green dynamic capabilities and green transformational leadership positively influence green creativity and green product development performance. Besides, this study indicates that the positive relationships between green product development performance and their two antecedents—green dynamic capabilities and green transformational leadership—are partially mediated by green creativity. It means that green dynamic capabilities and green transformational leadership can not only directly affect green product development performance positively but also indirectly affect it positively via green creativity. Hence, companies have to increase their green dynamic capabilities, green transformational leadership, and green creativity to enhance their green product development performance.     

A new look at the forward premium “puzzle”

We decompose the spot and forward rates into (permanent) nonlinear trend components and (transitory) stationary components. We examine the unbiasedness of the permanent (transitory) component of the forward rate in predicting the permanent (transitory) component of its corresponding future spot rate. The transitory component of the future spot rate under reacts to the transitory component of the forward rate. However, the permanent component of the forward rate is an unbiased predictor of the permanent component of the future spot rate. A robust nonlinear cotrending relation is also found between the forward and future spot rates and the hypothesis of the forward‐rate unbiasedness is sustained in the long run. These results suggest that the forward rate better explains the long‐term behavior of the future spot rate. Simulation analysis shows that if the transitory component of the forward rate fully predicts the transitory component of the future spot rate, the forward premium puzzle disappears. © 2010 Wiley Periodicals, Inc.

Consumption externalities,market imperfections and optimal taxation

In a dynamic model with a keeping‐up‐with‐the Joneses preference and market imperfections, we attempt to investigate under what circumstances and for what reason the optimal tax should be state‐varying. We extend the Ljungqvist and Uhlig (2000) proposition to include preferences that exhibit non‐homotheticity. We show that a keeping‐up‐with‐the‐Joneses preference (a non‐intertemporally‐dependent preference) can lead the social planner to commit to a state‐contingent tax on labor income. Moreover, the optimal labor income tax can be either procyclical or countercyclical with respect to economic fluctuations, this crucially depending on whether the level of contemporaneous consumption increases or decreases the wedge between the intertemporal substitution elasticity of households and of the social planner.     

The effect of consumer emotional disclosure on fairness perceptions

One way consumers cope with an unfair consumption experience is to express how they felt about it. Understandably, these disclosures are often rich with emotion. Does emotional disclosure in this context influence consumers' perceptions of fairness? Drawing hypotheses from the emotional disclosure literature, this research reveals that writing about emotions improves consumer fairness perceptions and satisfaction. However, the benefit of emotional disclosure disappears if the disclosure is solicited by the company perceived to be responsible for the unfairness and they do not offer redress. The findings lead to the recommendation that companies provide and facilitate opportunities for consumers to disclose to third parties the emotions arising from consumption experiences perceived as unfair. Implications for managing customer feedback, complaints, and negative word‐of‐mouth are discussed. © 2011 Wiley Periodicals, Inc.

JUMPING THE CURSE: EARLY CONTRACTING WITH PRIVATE INFORMATION IN UNIVERSITY ADMISSIONS*

This article introduces a new model of early contracting. Employers who have private information about the applicant's ability worry that applicants who accept their offer are precisely those who were not offered other jobs. To avoid this winner's curse, employers anticipate the time of contracting. The model is developed in the context of university admissions, and is shown to be consistent with several stylized facts in that “market.” We show that, in contrast to received wisdom, allocative efficiency may be improved by the presence of early contracting.
