Real estate agencies unevenly operate and specialize across space, price and type of properties, thereby segmenting the housing market into submarkets. We introduce a new methodology based on multipartite networks to detect spatial segmentation using online listings.

South Africa
After thirty years of democracy during which South Africa became an emerging economy, these dividing lines of electoral geography confirm that apartheid, as a multiscalar system of racial and ethnic segregation, remains key to understanding South African society spaces.

Commentary for the Tijdschrift voor Economische en Sociale Geografie’ annual lecture delivered at the 2023 AAG in Denver. I suggest to understand Desiree Fields’ intervention as a fourth conceptual moment in the study of housing markets and inequalities, for it brings racial capitalism and settler colonialism as theoretical starting points to analyse the political economy of housing in the era of digital property technologies.

The good, the bad and the tenant: rental platforms renewing racial capitalism in the post-apartheid housing market

This article examines how racial capitalism intersects with platform capitalism in post-apartheid South Africa. I argue that rental platforms, built upon technologies of credit scoring, extend the extractive logic of racial capitalism through two joint rentier mechanisms. the transformation of rental housing into a new asset class; the extraction and assetization of rental data.

In the age of platform capitalism, how is digital technology reconfiguring real-estate markets and access to housing? In Cape Town, South Africa, credit scoring—a form of selection based on financial behavior—has become the norm in this regard, contributing to the reappearance of apartheid-era segregation.

Urban geographies of financial convergence: situating Indian financial centres across global production and financial networks

With Dariusz Wójcik and Michael Urban
Published in Economic Geography.
Finance
Digital Technologies
How does finance transform global production networks and affect the hierarchy of financial centres? Recent advancements in the global production networks (GPNs) literature seek to better emphasize the role of finance by identifying where and how global financial networks (GFNs) intersect with GPNs. Financial centers (FCs) operate as key sites for articulating financial convergence, understood as the merging of financial and nonfinancial sectors enacted by cross-sectoral investments. Yet, how such entanglement both feeds on and impacts intercity networks, affecting metropolitan hierarchies, remains largely overlooked. Using a novel data set of 12,147 intersectoral, cross-border and domestic merger and acquisition deals involving finance and insurance firms throughout the period of 2000–20, this article unpacks the sectoral dynamics that underpin the intersection of GFNs with GPNs at the city level in India, the fifth largest economy in the world.

Digital Technologies
This paper explores the potential of FinTech to change the geography of finance and financial centres through a longitudinal and multiscalar analysis of FinTech in India. Using a financial ecology approach and a mixed-method framework, we document Bangalore’s emergence as India’s FinTech capital and the rise of New Delhi, demonstrate how Mumbai and Bangalore structure India’s financial geography as complementary ecosystemsm, and conceptualize FinTech in India as a “Tech-Fin-State” ecosystem.

À l’heure du capitalisme de plateforme, comment le numérique reconfigure-t-il les marchés immobiliers et l’accès au logement ? En Afrique du Sud, au Cap, la pratique du credit scoring est devenue la règle. Fondée sur une sélection par les comportements financiers, elle contribue à renouveler la ségrégation héritée de l’apartheid.

Dissertation

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.
