“…In the same period, girls also made gains relative to boys on standardized math and reading tests (Goldin, Katz, and Kuziemko, 2006;Cho, 2007) and grades (Fortin, Oreopoulos, and Phipps, 2015). Previous research has found evidence that boys are more sensitive than girls with respect to both parental (Bertrand and Pan, 2013;Riphahn and Schwientek, 2015) and school/preschool inputs (Krueger, 1999;Machin and McNally, 2008;Chetty et al, 2011;Havnes and Mogstad, 2011). This is supported by evidence showing that boys benefit more strongly than girls from early childhood interventions (Campbell et al, 2014;Conti, Heckman, and Pinto, 2015) and are more impatient (Bettinger and Slonim, 2007;7 Dohmen, Falk, and Sunde, 2010;Castillo, Ferraro, Jordan, and Petrie, 2011;Golsteyn, Grönqvist, and Lindahl, 2014).…”
