Stafan Hut (IDE’13) studies changes in diet quality among migrants to learn how changes in the environment affect dietary choice. Using detailed household level panel data on food purchases he finds that diet is very persistent in the short-run. After three to four decades, however, a migrant household’s diet quality converges almost fully to that of non-migrants in the destination. Stefan argues that these results are consistent with social interactions playing a role in driving differences in dietary choice across space, as opposed to differences in the retail environment or inherent food preferences.
Stafan graduated from IDE in 2013 and does his PhD at Brown. Please find below the link to the full paper as provided by his supervisor Prof Emily Oster.
