“…Many scholars [Cameron andHeckma, 2001, Moretti, 2012], indeed, attribute the lack of STEM graduates to the low quality of the US school system. Some studies look at the effects of school inputs (usually at the university level), like peers [De Giorgi et al, 2010, Anelli andPeri, 2015], teachers [Scott E. Carrell and West, 2010], teaching structure [Machin and McNally, 2008] and university coursework [Fricke et al, 2015]. Still, excluding some recent studies that evaluate the effects of secondary school curricula using quasiexperimental evidence [Joensen and Nielsen, 2009, Cortes et al, 2015, Goodman, 2012, there is little quantitative work on the effects of secondary school courses [Altonji et al, 2012].…”
