When It Rains It Pours: The Long-run Economic Impacts of Salt Iodization in the United States

Abstract: In 1924, The Morton Salt Company began nationwide distribution of iodine-fortified salt. Access to iodine, a key determinant of cognitive ability, rose sharply. We compare outcomes for cohorts exposed in utero with those of slightly older, unexposed cohorts, across states with high versus low baseline iodine deficiency. Income increased by 11%; labor force participation rose 0.68 percentage points; and full-time work went up 0.9 percentage points due to increased iodine availability. These impacts were largely… Show more

“…For example, Nilsson () examines a change in alcohol policy that affected binge drinking, Schwandt (2017) examines the impact of contracting influenza during pregnancy (which is preventable by vaccination), and Isen, Rossin‐Slater, and Walker () examine the long‐term effect of having been exposed to higher levels of particulate air pollution in utero or in early childhood. In a developing country context, several authors have demonstrated the effects of reducing infectious disease (Baird, Hamory Hicks, Kremer, & Miguel, ; Beach, Ferrie, Saavedra, & Troesken, ; Bhalotra & Venkataramani, ) and improving nutrition (Adhvaryu, Bednar, Molina, Nguyen, & Nyshadham, ). In an important study, Gertler et al () examined the importance of attending to psychological needs by training mothers to provide psychosocial stimulation.…”

“…The indirect benefits for children from having healthier parents is discussed in Section 5.2.16 A similar specification is used byAdhvaryu, Bednar, Molina, Nguyen, and Nyshadham (2014) in a study of the effect of salt iodization on labor force participation.17 The results are similar if we analyze the number of years an individual was exposed to the tuberculosis control campaign since birth.…”
