“…For instance, direct investments in child health, such as deworming (Baird et al, 2016a), nutritional supplementation (Hoddinott et al, 2008), and perinatal interventions (Charpak et al, 2016) have all been found to generate meaningful impacts on adult labor productivity. Certain investments in education, including cognitive stimulation in early childhood Kagitcibasi et al, 2009) and scholarship programs (Bettinger et al, 2018) also yield positive returns. Interventions that aim to improve child education, nutrition and health by leveraging a conditional cash transfer similarly appear to have persistent effects on earnings in some cases (Barham et al, 2017), although not in others: Molina Millán et al (2018b) find no meaningful impacts, possibly because their sample population is still relatively young.…”
