The (Express)Way to Segregation: Evidence from Chicago (Sara Bagagli)
Sara Bagagli (https://sarabagagli.github.io/) is an Assistant Professor of Real Estate Economics and Finance at London School of Economics and Political Science. Her research contributes to our understanding of what drives the (unequal) distribution of people and economic activity across space, focusing on the role of transportation infrastructure and urban forms. Her 2023 paper, The (Express)Way to Segregation: Evidence from Chicago (https://drive.google.com/file/d/1f45RDOze8EiGvJVv1chgOp3cOPu5i_qn/view), examines the long-established view that highways acted to increase segregation. Did expressways increase racial segregation in urban centers? Professor Bagagli establishes that expressways contributed to racial segregation in Chicago through two channels: (1) local price and amenity effects and (2) barrier effects. From these findings, she then constructs a structural urban model to study the link between urban barriers and racial preferences in shaping the allocation of people across space.

Published 27 Aug 2026 · Transcript excerpt
[…] And the notion of spatial equilibrium says that in equilibrium, by definition, no one wants to move. So that means that if in equilibrium there is a high amenity city and a low amenity city, there has to be some kind of compensating differential in terms of cost of living that makes the residents not want to move between these two cities. So that means the high amenity cities will be cities that, to fix ideas, let's think consumption amenities that households value. If a city has high consumption amenities, households will want to move into that city But not everyone can move there. It would be inconsistent with spatial equilibrium. […]
