You can also refer to these as "external economies of scale". DC and politics/government seems like a clear pick. High Point, NC used to be one for furniture. [1]<p>Wasn't Michigan one for the automotive industry? I don't know that for sure, though.<p>[1] <a href="https://en.wikipedia.org/wiki/High_Point,_North_Carolina#Evolution_of_furniture_industry" rel="nofollow">https://en.wikipedia.org/wiki/High_Point,_North_Carolina#Evo...</a>
I’m not sure “Schelling point” is the right term for places that have become hubs of particular industries because of their well-known connections to people and organizations in those industries. This isn’t quite the same as the tacit coordination Schelling discussed in <i>The Strategy of Conflict</i> (his 1960 book on game theory), in which participants have to make a common choice <i>without</i> being able to communicate.<p>That said, other U.S. examples include Los Angeles for motion pictures and television, Nashville for music, Houston for oil and gas, Phoenix for semiconductors, Sioux Falls for credit cards, and San Diego for triathlon.
