Jullien, Sinclair and Garner (2016) (henceforth JSG) state that they seek to ‘appraise the methods’ of three recent papers that estimate long-run impacts of mass deworming on educational or economic outcomes. This commentary focuses on their discussion of Baird, Hicks, Kremer and Miguel (2016) (henceforth Baird).We welcome scrutiny of our work, and appreciate the opportunity to discuss JSG. Baird finds evidence of gains in some educational and labour outcomes 10 years after a deworming programme in 75 Kenyan primary schools. Some gains are found in the full sample, and others among either males or females, in ways that are sensible given the context, e.g. there are gains in manufacturing employment among males but not females, fewer of whom work in this sector in Kenya. Below we discuss JSG’s claim that the evidence in Baird is unreliable. It is not surprising that any two scholars might interpret a body of results differently, but JSG make a series of claims that appear overstated or are somewhat misleading.
