My PhD dissertation was entitled “A city to sell. Digitalization and financialization of the housing market in Cape Town: stratification & segregation in the emerging global city”.
The thesis demonstrates how the digitalization of the real estate industry, structured around the implementation of credit scoring and the rise of real estate platforms, profoundly reshaped the functioning of the housing market in post-apartheid South Africa. This re-mediation of the market enabled a selective financialization of housing, enacted by restrictive lending policies and by the consolidation of the private rental sector, characterized by the emergence of institutional investors. This evolution of the market renewed mechanisms of social stratification and patterns of urban change in Cape Town.
I used a mixed-method framework combining expert interviews, participant-observation, and spatial data science. I conducted 18 months of in-depth fieldwork across the real estate industry (real estate agents, mortgage lenders, institutional investors, buyers and tenants). In parallel, I source Deeds data and longitudinal census data to analyze how the spatial dynamics of price and credit influence the evolution of urban segregation, building a new database of 900,000 residential transactions, while reconstructing the zoning of apartheid with GIS and archival maps. I used open source tools such as R and QGIS.
