“While it would be nice to simply wait for the lessons from America’s metros to bubble up to the federal level, we may need to more quickly bottle the magic elixir,” note authors Manuel Pastor and Chris Benner in their book, Equity, Growth, and Community. Pastor and Benner analyze 11 U.S. metropolitan regions that have demonstrated resilience despite economic restructuring and find the presence of “epistemic communities,” partnerships that bring together diverse stakeholders and knowledge sources, which enable communities to better withstand shock. To scale these collaboratives, Pastor and Benner suggest the creation of a learning network in which communities can share their experiences.
