Housing the Homeless: The Effect of Placing Single Adults Experiencing Homelessness in Housing Programs on Future Homelessness and Socioeconomic Outcomes

Using linked administrative records and caseworker placement tendencies, I find that rapid housing placement reduces returns to the homeless support system, crime, and emergency cash assistance, with no detectable effect on health services utilization.

The Effect of Immigration Restrictions on Local Labor Markets: Lessons from the 1920s Border Closure
with Ran Abramitzky, Philipp Ager, Leah Boustan, and Casper W. Hansen

Better Partitions of the United States into Geographic Labor Markets

Homeless Housing and Local Homelessness: Evidence from Los Angeles Communities
single-authored
I construct a longitudinal inventory of physical homeless housing and shelter sites in Los Angeles and link it to small-area measures of sheltered and unsheltered homelessness. The analysis studies spatial sorting, spillovers, and changes around first exposure to temporary and permanent housing sites.
