“…A number of recent studies have shown, with plausible strategies for identifying causal impacts, that girls' attitudes toward, and willingness to study, quantitative and scientific subjects are affected by the social influence of family, peers, and role models on their perceived competence in math and beliefs about gender‐appropriate behavior. This may explain why many gender gaps in performance and attitudes, such as the male advantage in math and higher levels of female risk aversion, emerge only in adolescence as gender identity concerns intensify (Fahle and Reardon, 2018; Andreoni et al ., forthcoming). There has been less research in economics on the educational underperformance of boys, and much of it is descriptive, pointing to behavioral problems more prevalent among boys as evidence of a deficit in non‐cognitive skills that increases the costs of persisting in formal education (Goldin et al ., 2006; Becker et al ., 2010).…”
