# Chase Abram

I am a PhD Candidate in the Kenneth C. Griffin Department of Economics at the University of Chicago. My research concerns firm dynamics and labor markets in the macroeconomy, with an eye towards bettering our understanding of worker job flows and earnings inequality. Additionally, I study the the spatial distribution of economic activity, with a focus on developing tools for modelling dynamics in quantitative spatial models.
