“…Similar pathways suggest that health investments pay off over and above the increases in longevity and reductions in morbidity that are beneficial at the individual level. The literature focuses especially on the following channels: (1) healthier workers are more productive and contribute more to aggregate output (Fogel 1994(Fogel , 1997Shastry and Weil 2003;Weil 2007;Kuhn and Prettner 2016;Bloom,Kuhn, and Prettner 2019b); (2) healthier children tend to perform better in school, which enhances their potential for human capital accumulation (Miguel and Kremer 2004;Bleakley and Lange 2009;Field, Robles, and Torero 2009;Bleakley 2010Bleakley , 2011Bloom, Kuhn, and Prettner 2017b;Baldanzi et al 2021); (3) healthier individuals are more inclined to educate themselves and to invest (Ben-Porath 1967;Kalemli-Ozcan et al 2000;Bloom, Canning, and Graham et al 2003a;2007;Bloom, Canning, Moore 2014b;Cervellati andSunde 2005, 2013;Prettner 2013); and (4) health investments (such as vaccination) that cure or prevent infectious diseases have positive spillovers to other individuals (Luca and Bloom 2018). Here, too, the positive effect found in micro-based studies is consistent with the macro-based evidence that health is an important determinant of economic growth (Barro 1991;Sala-i-Martin 1997;Sala-i-Martin,Doppelhofer, and Miller 2004;Lorentzen et al 2008;Suhrcke and Urban 2010;Aghion, Howitt, and Murtin 2011;Cervellati and Sunde 2011;Bloom, Canning, and Fink 2014a;Bloom et al 2019a).…”
