"A World More Concrete marks the arrival of an exciting new voice in American political and social history. Through a fascinating history of Miami, Connolly brings together politics, culture, and economics in a riveting account of how shared understandings of property rights and real estate were central to the racial segregation that has plagued America's cities. Connolly unpacks the complex dynamics of property transactions and urban development, meticulously analyzing all the various institutional actors who shape this market in order to understand the political economy of racism."
