Gender differences in decision making is a topic that has attracted much attention in the literature and the debate seems to be inconclusive. In a recent study, Bouchouicha et al. (2019) using data from an incentivised experiment with almost 3000 students and 30 different countries, estimate gender effects assuming four commonly employed definitions of loss aversion. Despite the fact that their analysis is based on the same data and the same functional forms and econometric setup, their results are inconclusive regarding the existence and the direction of gender effects for loss aversion. In this study, we investigate two extensions of their work in an effort to shed some light on the potential reasons behind this contradictory result. In particular, we explore whether: (1) a more flexible estimation method that allows for individual heterogeneity and generates more robust estimates in the presence of noise and; (2) a different utility function, can generate more robust inference regarding gender effects. We show that while a more flexible Hierarchical Bayesian estimation method is not sufficient to explain the contradictory results, an alternative utility function detects a uniform gender effect, with women being always more loss-averse, regardless the adopted definition of loss aversion.

The lost-letter technique (Milgram et al., 1965) has been used for almost 60 years to measure social attitudes and helping behavior in psychological, sociological, and economic research. We provide a meta-analysis of lost-letter experiments to summarize the evidence. We analyze 78 studies with an overall sample size of 53,504 letters from 18 countries on five continents. We find an average return rate of 50 percent across all countries. Our meta-analysis shows that the return rate is lower for political or deviant issues. Stamped letters are also more likely to be returned, but letters with money are not more likely to be returned. A high socio-economic environment increases the chances of the return. We conclude that in line with the lost-letter paradigm, the technique allows capturing citizens’ attitudes toward the issue communicated. However, citizens do not act selflessly but react differently depending on the type of incentives.

We use a lab experiment to explore whether gender composition and gender identity salience influence team coordination. Identity in the experiment is induced using gender-specific and neutral avatars. In contrast with many previous studies, we do not find the presence of in-group favoritism, irrespective of whether gender identity or random avatars define the group. In addition, behavior remains unchanged when the gender of the counterpart is revealed. However, females are found to cooperate significantly more when gender information is disclosed, implying an elevation in the salience of gender identity induces the females to choose based on social expectations. This research adds to the discourse on gender dynamics in decision-making and suggests that gender identity plays a role in economic choices, innovating traditional views on diversity in teamwork. Our research sheds light on the intricate dynamics of gender composition in team settings, particularly under conditions of risk and uncertainty. These findings have the potential to inform both organizational practices and public policy, thereby contributing to a more equitable and efficient labor market.
