I have four brilliant students graduating this year. You should check out their websites!
Zahin Haque's dissertation shows that poor households both consume and produce relatively larger shares of staple foods, develops a theory to explain the relationship between the well-known consumption Engel curve and her new fact about the production Engel curve, and estimates a structural model to understand the effects of counterfactual policies such as food subsidies. In other work she uses tools from asset pricing to understand how crop choices respond to risk.
Vasily Rusanov's dissertation studies internal migration in the United States in the 19th century. He quantifies a new explanation for how migrants from the East picked their destinations - crop similarity - and shows that there were important spillovers: frontier counties with more (internal) immigrants from more educated states also had higher education for native born children. Vasily digitized the Census of Social Statistics, an enormous public good, and uses this new resource to show that part of the channel was cheaper schools.
Isabelle Salcher's main dissertation, which is currently in the field, studies gender roles and how norms about home production affect entrepreneurship. She has developed and managed impact evaluations and surveys around the world, and has written several interesting papers on both labor markets and gender inequality, including a large-scale RCT in Ghana studying the effects of apprenticeship programs.
Lena Song's dissertation studies persuasion, and uses a model + experimental data to discuss how people with different backgrounds are influenced by different types of messages, where the potential for backlash means that the same message can have opposite effects on people's behavior & beliefs. Lena has written many excellent papers at the intersection of firms, information technology, and inequality (and you don't have to take my word for it, since journal editors also agree)
