I don’t always agree with economist Edward Glaeser, but I really enjoyed the talk that he gave at the Vancouver Urban Forum back in 2012 (at least part 2 of it). I came across it on Twitter today and, since it only has about 300 views, I figured that some of you also haven’t seen it.

The argument he makes is that knowledge and education are the bedrock of cities. And since we continue to cluster in cities, despite all of our technological advances, knowledge is clearly more important than space. One of the ways he defines cities is by their lack of space and the closeness of the people.

Of course, this isn’t anything new. If you’ve read his book Triumph of the City, you’ve heard all of this before. But that didn’t stop me from enjoying his talk. It’s a great overview of declining transportation costs, locational advantages, agglomeration economies, the importance of urban density, the impact of small and large firms in a city, and so on.

I also really liked this idea that knowledge is worth more than space. So if you have 20 minutes and you want to get geared up about cities, have a watch.
