Joe Cortright recently wrote about a study by Kate Pennington (UC Berkeley), which looked at the impact of housing production on legal eviction in San Francisco. The goal was to figure out if new housing supply actually causes displacement.
To do this, Pennington went block-by-block and looked at new housing projects, as well as over a decades’ worth of eviction notices.
The relationship between the two was found to be “statistically indistinguishable from zero.” In other words, the “monthly probability of an eviction notice” does not change when new housing supply is completed nearby.
Some have been critical of her findings and some have questioned whether legal eviction notices are, in fact, the right proxy for displacement.
But I agree with Joe Cortright in that this still feels like a meaningful relationship to understand, especially when we’re talking about a tight housing market like San Francisco’s.

Uber CEO Dara Khosrowshahi was in Toronto today, where he announced that the company plans to invest more than $200 million over the next five years to expand the autonomous vehicle research lab that it already has here in the city.
The Toronto outpost of Uber’s Advanced Technologies Group (ATG) – which is its only international outpost – is led by renowned University of Toronto professor, Raquel Urtasun. She is also the cofounder of the Vector Institute for Artificial Intelligence and splits her time between Uber and UofT.
With this investment, Uber also expects to open its first engineering facility in Canada and grow its local headcount to 500, up from the 200 or so it has today. Some of these hires will be local. Some will be international. And some will be transplants from Uber’s other offices.
Also notable about the announcement is that Khosrowshahi mentioned that he thinks fully autonomous vehicles roaming the streets of our cities is a good 10 years away. But I wonder if that isn’t political PR speak intended not to spook its drivers. So are we closer to the mid-2020′s?
Either way, as a proud Torontonian and UofT alumnus, I was happy to see this announcement. I think it’s far more exciting than the Apple event that took place earlier this week.
This is an interesting working paper by a team of researchers at NYU’s Marron Institute of Urban Management. The paper examines the relationship between urban density and organized violence, first in Colombia and then within a sample of 200 global cities.
The finding is that organized violence actually increases the population density of the surrounding areas within a city because it creates a kind of “invisible wall” – effectively a no-go zone.
This makes perfect intuitive sense, but it’s not something I ever considered. Geography and other natural constraints typically drive density. Think about the island of Manhattan. But so too can invisible walls.
