Access to the Exclusive City

I recently coauthored an article in Urban Studies with Julia Harten titled “Access to the Exclusive City: Home Sharing as an Affordable Housing Strategy.” We examined how shared housing serves increasingly diverse populations as a pathway into otherwise unaffordable housing submarkets.

From the abstract:

Home sharing, particularly via online platforms, is becoming a mainstream housing strategy as social processes evolve and housing costs rise. Recent research has studied shared rentals as a modality for students and kin-based households, as one strategy among diversifying pathways to housing and as a social phenomenon. However, we still know little about whether it actually creates opportunities for home seekers in unaffordable markets. Analysing online rental listings in Los Angeles, we find that shared rentals are both more affordable and more widely available across diverse neighbourhoods than traditional whole-unit rentals. Shared rentals have historically been understudied due to their limited data trail, but they offer important entryways into unaffordable markets. We argue for shared housing research to shift its traditional focus away from students and young adults and towards a broader exploration of the diverse populations that may benefit from or depend on shared housing.

AI and NLP for Urban Mixed Methods Research

One area where urban AI research seems promising is in mixed methods work. For example, it’s hard to use traditional qualitative methods on really large text data sets because of the overwhelming manual labor involved. But if you could train a model to do, say, topic labeling for you, you’d be able to (potentially) analyze nearly unlimited text data nearly instantly after that initial training work. The mixed methods holy grail.

I coauthored an article recently in Computers, Environment and Urban Systems with Madison Lore and Julia Harten which takes up this challenge. Using Los Angeles’s housing crisis and rental market as a case study, we demonstrate how and when modern AI and NLP techniques can generate qualitative insights on par with traditional manual techniques, but at a far larger scale and requiring far less labor.

Housing Tech and Tilted Platforms

I have a new article out now in a special issue on platform urbanism, co-authored with Max Besbris, David Wachsmuth, and Jake Wegmann, titled Tilted Platforms: Rental Housing Technology and the Rise of Urban Big Data Oligopolies. We reflect on short-term and long-term rental housing technologies and how they’re affecting the housing search, equity, and affordability.

From the abstract:

This article interprets emerging scholarship on rental housing platforms—particularly the most well-known and used short- and long-term rental housing platforms—and considers how the technological processes connecting both short-term and long-term rentals to the platform economy are transforming cities. It discusses potential policy approaches to more equitably distribute benefits and mitigate harms. We argue that information technology is not value-neutral. While rental housing platforms may empower data analysts and certain market participants, the same cannot be said for all users or society at large. First, user-generated online data frequently reproduce the systematic biases found in traditional sources of housing information. Evidence is growing that the information broadcasting potential of rental housing platforms may increase rather than mitigate sociospatial inequality. Second, technology platforms curate and shape information according to their creators’ own financial and political interests. The question of which data—and people—are hidden or marginalized on these platforms is just as important as the question of which data are available. Finally, important differences in benefits and drawbacks exist between short-term and long-term rental housing platforms, but are underexplored in the literature: this article unpacks these differences and proposes policy recommendations.

Rental Housing Spot Markets

My new article, “Rental Housing Spot Markets: How Online Information Exchanges Can Supplement Transacted-Rents Data,” with Jake Wegmann and Junfeng Jiao is now published in the Journal of Planning Education and Research (download free PDF).

How much does it cost to rent a typical apartment in your city? Answering this basic housing question can be surprisingly difficult. Consider the case of San Francisco in early 2018.
