Revisiting the impact of dams on malaria and agriculture

Mary, Sébastien; Craven, Kyle; Stoler, Avraham; … - In: Economies : open access journal 11 (2023) 7, pp. 1-19

We estimate the effect of large dams on malaria incidence in India between 1975 and 1995. We combine instrumental variables approach with a panel model with unobserved common factors allowing us to fully capture the endogeneity of dam location and unobserved time-varying heterogeneity. Dams...
