“…For example, Baker et al (2008) provide evidence on the short-run developmental effects of universal child care in Quebec, Canada, while Gupta and Simonsen (2010) and Black et al (2014) provide medium-run evidence for the Danish and Norwegian systems, respectively. In the United States, Herbst andTekin (2012, 2016) estimate the short-and medium-run impact of the CCDF, a subsidy program restricted to the working poor, while a large number of studies examine the short-and medium-run impact of pre-kindergarten programs, only some of which are universal (e.g., Gormley and Gayer 2005;Fitzpatrick 2008;Barnett et al 2013;Cascio and Schanzenbach 2013;Weiland and Yoshikawa 2013). In addition, a noteworthy paper by Cascio (2009a), which estimates the long-run impact of kindergarten introduction in the United States, finds some positive effects for white adults but not for black adults.…”
