    Abstract: We experimentally assess the disposition effect and return performance, using electroencephalogram to measure the brain activity of the participants. The design of the experiment follows a previous protocol (Frydman et al., 2014). Our sample was made up of 12 undergraduates (all male, age range 18 to 29, mean age 22.2) and five professional stock traders (all male, age range 21 to 37, mean age 30.2). We find neural support for the finding that professionals are more likely to escape the disposition effect (Da Costa Jr et al., 2013). We also find higher heart rate variability and brainwave activation are positively related to stock returns. Electrical activity tends to increase with returns, mainly for the beta waves that are activated in conscious states.

    Abstract: Reducing food waste is a major challenge in achieving a more sustainable food system. This research analyzes the psychosocial factors and cognitions that determine actual food waste behaviors in mass catering services. 216 customers of a French worksite cafeteria completed an online questionnaire based on the theory of planned behavior extended to moral norms. Over a period of four days, the quantity of food left by each respondent was weighed and linked to the answers. Findings indicate that food waste behaviors in mass catering setting are mainly drive by perceived behavioral control. Analysis of the underlying control beliefs suggests that interventions should focus on two specific aspects: improving food quality and making portion sizes more flexible.
    Abstract: Réduire le gaspillage alimentaire est un défi majeur pour parvenir à un système alimentaire plus durable. Cette recherche analyse les facteurs psychosociaux et les cognitions qui déterminent les comportements de gaspillage alimentaire en restauration collective. 216 clients d’un restaurant d’entreprise en France ont rempli un questionnaire en ligne basé sur la théorie du comportement planifié. Sur une période de quatre jours, la quantité de nourriture laissée par chaque répondant a été pesée et reliée aux réponses. Les résultats indiquent que les comportements de gaspillage dans ce contexte de consommation dépendent principalement du contrôle comportemental perçu. L'analyse des croyances de contrôle sous-jacentes suggère que les interventions devraient se concentrer sur deux aspects spécifiques : améliorer la qualité des repas et apporter plus de flexibilité dans la taille des portions servies.

    Abstract: This paper develops a model which provides a characterization of the joint distribution of the duration of search, accepted wages and skills with unobserved heterogeneity based on Eckstein and Wolpin (1995). We aim to estimate the effect of cognitive and socio-emotional skills on first job wages and duration of job search. Observed and unobserved heterogeneity are exploited as sources of identification. The data is drawn from the 2010 ENHAB which has not been used for this purpose before and which contains full retrospective information on first job outcomes and children. The model is estimated through a maximization of the joint Likelihood. Preliminary results regarding wages show that socio-emotional skills are the most valued among high skilled individuals, whereas cognitive skills are the most valued among low skilled individuals. Predicted wages for type I individuals are always above the observed wage, for every schooling level. Regarding duration of first job search, results show that the socio-emotional high skilled individual receives more job offers than the cognitive high skilled with the same schooling level.
