This is an astounding book for anyone interested in an in-depth look, and I wrote about it in a post in January, read at https://riverparkwayblog.wordpress.com/2018/01/09/learning-about-suburbia/
Here is an excerpt from one of the articles I was just reading.
“A number of economic studies, however, find considerable support for the existence of urbanization economics and a nonrivalrous relationship between central cities and their suburbs. The economists Edward Glaeser, Hedi Kallal, Jose Scheinkman, and Andei Shleifer find that industrial diversity fosters city growth, indicating that urbanization economies dominate and cities grow best when knowledge spreads from one industry to another. Applied to the central city-suburb relationship, these findings suggest that the exchange of ideas between industries ties together the economic fortunes of all parts of an urban area.” (p.330)
Infinite Suburbia (2017). Edited by Alan M. Berger, Joel Kotkin, with Celina Balderas Guzman. Princeton Architectural Press: New York.
For an interesting thought experiment, substitute government for industries and quality of life for economic fortunes, if this kind of city/county partnership could arise around homelessness right here in Sacramento.
