Over the past few months on this blog, I’ve started to introduce business terms into the way I describe and talk about cities. I’ve referred to residents and visitors as customers of a city, experiences within a city as products and services, and cities themselves as businesses. Until now though, I hadn’t explicitly talked about this parallel or fleshed it out in any sort of detail. But I think it’s an interesting one so I’d like to do a bit of that today.

The reason I started referencing cities with business terms is because I think it speaks to 3 important characteristics of cities. First, cities, just like businesses, are in direct competition with each other. We rank cities. We compare GDP per capita. And they fight, or at least should, to attract the best people and to achieve economic dominance.

Second, city prosperity can be ephemeral. We tend to think of cities as being quite permanent–centuries old–but history is littered with failed cities or cities that simply lost their economic importance (see Detroit). Consider this: The center of trade at one point was the Mediterranean Sea. Then, as the New World emerged, it shifted to the Atlantic. And now, one might argue that it’s moving over to the Pacific (and Asia). Either way, these macro shifts push certain cities to thrive and others to decline. The time horizon is longer than, say the rise and fall of Blackberry, but it’s similar nonetheless. Nothing is guaranteed.

Third, cities have become centers of lifestyle and consumption. That’s why I previously argued that any economic development strategy should consider lifestyle, and whether or not people actually want to live in the place. In business terms, you need to offer products and services that people actually want. You need to respond to customer needs.

And if you think of cities in this way, I think you’ll come to the conclusion that, just like businesses, strong cities require strong leadership and management. They need to ensure that they’re delivering the right products and services to their customers and that they’re staying ahead of the innovation curve.

The switching costs may be higher for cities compared to, again, something like a mobile phone, but that doesn’t mean people won’t eventually vote with their feet and leave for somewhere better.

This morning I woke up to a tweet from somebody asking me why–despite my obvious love of cities and real estate–do I seem more influenced by venture capitalists on my blog. He wondered if it was because of a lack of public/online real estate thought leaders.

I responded by saying yes; that’s part of the reason. I honestly can’t think of one real estate developer that hosts a personal and regular blog. (If you know of any, please pass them along.) Whereas I can’t think of a major VC who doesn’t blog.

Sure there are other real estate professionals who blog, but a lot of those sites just feel like giant lead generation tools and those aren’t enjoyable to read. I’m trying not to create that kind of blog. The trust of readers is more important to me than trying to promote my businesses.

But the other reason I often cite venture capitalists and “tech” centric topics is because I believe in cross pollinating industries. I don’t believe the world operates neatly under silos and neither should our minds and businesses. I’ve also argued many times before that with software eating the world, nobody should be ignoring technology.

At the same time, the consumer web feels to me like this profound social force changing the way people live and interact with each, which, if you think about it, is what cities have always been about. And so I see all kinds of interesting overlaps.

Of course, I also look to planners, designers and other urbanists for inspiration. But I don’t like to do so exclusively. Industries, like anything else, can quickly become insular–whether tech or urban planning. My interest–and the focus of this blog–is cities. And I will continue to incorporate ideas and viewpoints from any discipline that I think touches them.
