A large literature establishes that cognitive and non-cognitive skills are strongly correlated with educational attainment and professional achievement. Isolating the causal effects of these traits on career outcomes is made difficult by reverse causality and selection issues. We suggest a...

We estimate the impact of changes in unearned income on the height and weight of young children in a developing country. As source of variation we use changes in the eligibility criteria for receipt of an unconditional cash transfer in Ecuador. Two years after families lost the transfer, which...

It is an established fact that gay men earn less than other men and lesbian women earn more than other women. In this paper we study whether differences in competitive preferences, which have emerged as a likely determinant of labour market differences between men and women, can provide a...

Men are generally found to be more willing to compete than women and there is growing evidence that willingness to compete is a predictor of individual and gender differences in career decisions and labor market outcomes. However, most existing evidence comes from the top of the education and...

We present evidence on the role of the social environment for the development of gender differences in competitiveness and earnings expectations.

We estimate the impact of changes in unearned income on the height and weight of young children in a developing country. As source of variation we use changes in the eligibility criteria for receipt of an unconditional cash transfer in Ecuador. Two years after families lost the transfer, which...

A large empirical literature in behavioral economics investigates heterogeneity across individuals and groups in preferences for competition. In this study, we provide a more detailed view on competitiveness by differentiating between four different motivations for entering competitions –...

Competitive environments often leave room for "dirty" practices such as sabotage, retaliation, or dishonesty. We use an online experiment to document aggregate levels and individual differences in the willingness to engage in dirty competition and in the willingness to enter competitions where...
