“…This paper relates to a broad literature on migration, which represents an important margin of economic adaptation. The Dust Bowl provides a rare opportunity to explore migration responses to a permanent collapse in the local environment, in contrast to more exploration of migration responses to more-temporary natural disasters and weather shocks (Piguet, Pécoud and de Guchteneire, 2011;Boustan, Kahn and Rhode, 2012;Marchiori, Maystadt and Schumacher, 2012;Bohra-Mishra, Oppenheimer and Hsiang, 2014;Cai et al, 2016;Deryugina, 2017;Deryugina, Kawano and Levitt, 2018;Boustan et al, 2019;Deryugina and Molitor, 2019;Mahajan and Yang, 2020;Spitzer, Tortorici and Zimran, 2020). The migration literature has long considered how migrant selection varies across contexts (Roy, 1951;Borjas, 1987), and characterizing the Dust Bowl migrants and their experiences provides an opportunity to refine this archetype of environmental refugee.…”
