Men are from Mars and Women too: a Bayesian meta-analysis of overconfidence experiments, with Oriana Bandiera, Barbara Petrongolo and Nidhi Parekh. Economica, 89: S38-S70 (2022).
Gender differences in self-confidence could explain women's under-representation in high-income occupations and glass-ceiling effects. We draw lessons from the economic literature via a survey of experts and a Bayesian hierarchical model that aggregates experimental findings over the last 20 years. The experts’ survey indicates beliefs that men are overconfident and women underconfident. Yet the literature reveals that both men and women are typically overconfident. Moreover, the model cannot reject the hypothesis that gender differences in self-confidence are equal to zero. In addition, the estimated pooling factor is low, implying that each study contains little information over a common phenomenon. The discordance can be reconciled if the experts overestimate the pooling factor or have priors that are biased and precise.
Working Papers
Women and Cash transfers: how program design and local conditions relate to causal estimates of impact, with Gabriela Diaz-Pardo.
In this paper, we conduct a systematic review of the literature on the impact of cash transfers on women’s employment and empowerment. We construct a dataset of 265 impacts of cash transfers on adult women across 56 studies and 30 programs in Lower and Middle-income countries. Our dataset is the first that matches estimated treatment effects with harmonised information on the design of cash transfer programs, including the transfer size, payment methods and frequencies, and program conditionalities. Across studies, we find that cash transfers have a positive and insignificant impact on women’s employment and empowerment. We use our data to explore how the impact of cash transfers differs by program design features and baseline country conditions, including local labor market structures and gender social norms. We find that cash transfers have a larger impact on women’s labor force participation when they are larger in size, and when there is a higher proportion of women who work in formal employment before the program evaluation. Overall, our results suggest that cash transfers have more meaningful impacts on women’s employment and empowerment when pre-existing gender constraints are low. Our findings highlight the importance of interpreting estimated program impacts in the context of country-level conditions and program design.
Gender differences in altruism: a Bayesian hierarchical analysis of dictator games.
I aggregate evidence on gender differences in dictator game giving from experiments published in all working papers and peer-reviewed journals since 1990. Using a two-stage Bayesian hierarchical model, I find that on average women give around 3 percentage points more than men in studies of dictator games. I show that while this estimate is smaller than that found in previous studies, it is likely to be an upper bound estimate due to publication bias. Using a truncated selectivity model, I estimate the conditional probability of publication as a function of experiment results. My findings suggest that experiments that find positive results (i.e. women contribute more than men) and are statistically different from zero at the 5% level, are around 13 times more likely to be published than statistically significant and negative results.
