The disposition effect and loss aversion: Do gender differences matter?

This paper analyzes gender differences in the disposition effect in an experiment based on Weber and Camerer (1998). The results emphasize that female investors realize less capital losses, have significantly higher disposition effects and are more loss averse than men.     

Inside the Crystal Ball: New Approaches to Predicting the Gasoline Price at the Pump

Appropriate real‐time forecasting models for the US retail price of gasoline yield substantial reductions in the mean‐squared prediction error (MSPE) at horizons up to 2 years as well as substantial increases in directional accuracy. Even greater MSPE reductions are possible by constructing a pooled forecast that assigns equal weight to five of the most successful forecasting models. Pooled forecasts have lower MSPE than the US Energy Information Administration gasoline price forecasts and the gasoline price expectations in the Michigan Survey of Consumers. We also show that as much as 39% of the decline in gas prices between June and December 2014 was predictable. Copyright © 2016 John Wiley & Sons, Ltd.     

Career mentoring in context: A multilevel study on differentiated career mentoring and career mentoring climate

This study explores how supervisor career mentoring contributes to contemporary organizational career development, which strives to foster employees' promotability while strengthening their intention to stay. Specifically, we focus on the implications of career mentoring in team contexts. Applying a multilevel framework, we distinguish between individual‐level differentiated mentoring (i.e., an employee's mentoring perceptions as compared to those of other team members) and group‐level career mentoring climate (i.e., the average perception across all group members). In a workplace setting, we collected data from vocational job starters (N ranged from 230 to 290) and their company supervisors (N ranged from 56 to 68). We find that career mentoring climate positively relates to promotability, more so than differentiated career mentoring. Both career mentoring climate and differentiated career mentoring are positively related to the intention to stay. At the individual level, this relationship is mediated by job satisfaction. We discuss theoretical and practical implications of differentiated and group‐level mentoring.     

The Effect of Behavioral Contagion and Tie-Strength on Calorie Intake in Food Courts

Major contributors to the obesity epidemic are societal and result from sedentary lifestyles and consumption of high-calorie diets. Previous studies suggest that food choice behavior is socially transmissible. Hence, knowledge of the impact of social influence on calorie intake is critical to improve the understanding about the outcomes of policies related to healthful diets. There is the need to analyze the influence of social networks on choosing food in a public place. Thus, we interviewed groups of food court patrons in an all-you-can-eat college dining hall. Results show individuals dining in a group with at least one obese group member are consuming more calories from high-calorie foods and fewer calories from low-calorie foods. Food-related interactions in a group influenced food consumption. Hence, dining with obese peers likely increases calorie intake.     

Awareness Advertising and International Market Segmentation

In recent years, multinational corporations have increasingly employed advertising in markets where their products are not available. Such ‘awareness advertising’ is only in small part for products that are likely to be introduced in those markets in the near future. A significant and larger part of awareness advertising is for products that are unlikely to be sold in the particular market because of government restrictions on commercial importation and sale. In this paper, we will analyse the motivation behind the use of awareness advertising, the benefits that multinational firms may receive from such advertising and its implications for international market segmentation. The paper concludes with a discussion of areas for fruitful future research on awareness advertising.
