Brandon DonnellyCanada must become a global superpower
The silver lining to the US starting a trade war with Canada and regularly threatening annexation is that it has forced this country out of complacency. Indeed, I'm hard pressed to remember a time, at least in my lifetime, when patriotism and nationalism has united so much of Canada. According to a recent survey by Angus Reid, the percentage of Canadians expressing a "deep emotional attachment" to the country jumped from 49% in December 2024 to 59% in February 2025. And as further evidence of...
Brandon DonnellyThe bank robbery capital of the world
Between 1985 and 1995, Los Angeles' retail bank branches were robbed some 17,106 times. In 1992, which was the the city's worst year for robberies, the number was 2,641. This roughly translated into about one bank robbery every 45 minutes of each banking day. All of this, according to this CrimeReads piece by Peter Houlahan, gave Los Angeles the dubious title of "The Bank Robbery Capital of the World" during this time period. So what caused this? Well according to Peter it was facil...
Brandon DonnellyThe story behind those pixelated video game mosaics in Paris
If you've ever been to Paris, you've probably noticed the small pixelated art pieces that are scattered all around the city on buildings and various other hard surfaces. Or maybe you haven't seen or noticed them in Paris, but you've seen similarly pixelated mosaics in one of the other 79 cities around the world where they can be found. Or maybe you have no idea what I'm talking about right now. Huh? Here's an example from Bolivia (click here if you can't see...

We often talk about agglomeration economies in terms of their horizontal clustering within cities. But a new paper in the Journal of Urban Economics – summarized here by Richard Florida – has looked at the other dimension: the vertical clustering of economic activity within tall buildings.
Here is an excerpt from Florida’s piece in CityLab:
Economic activity is also sorted vertically, with higher-profile and more profitable firms occupying higher building floors. Law offices are disproportionately represented on the highest floors, taking up more than a third of floor space above the 40th floor, compared to 12 percent of floor space between the second and 40th floors. Finance, insurance, and real estate take up roughly 20 percent of floor space above the 40th floor, compared to 23 percent between the second and 40th floors. Business services, engineering, and miscellaneous other industries are also more likely to take up more space below the 40th floor.
The other takeaway is that there appears to be a greater rent premium attached to higher floors (vertical movement) than for being located closer to the central business district (horizontal movement). This surprised me. But I also don’t have access to the full paper. Is the dataset just US cities?
Nevertheless, the idea of a vertical city interests me a lot. And I agree with the authors of the report that, for perhaps obvious reasons, it is far less studied compared to horizontal development patterns.
