Clustering

Clustering is the central mechanism of Richard Florida’s The New Urban Crisis, and the concept Kyle’s marginalia returns to most. Florida’s formulation: “The clustering force is at once the main engine of economic growth and the biggest driver of inequality.” Two kinds of clustering happen in cities — of firms and industries, and (more importantly) of “skilled and ambitious people” — and the concentration of talent and economic activity in fewer and fewer places is “now the basic engine of innovation and economic growth,” driving the Santa Fe finding that each doubling of a city’s population makes its residents ~15% more innovative, productive, and wealthy. But the same force divides the world’s cities into winners and losers and makes the winners unaffordable for all but the most advantaged. Florida’s policy agenda flows from this: reform zoning and tax policy “to ensure that the clustering force works to the benefit of all,” and invest in infrastructure (mass transit over highways) “to spur density and clustering and limit costly and inefficient sprawl.”

For Kyle the clustering paradox reads as an investment thesis as much as a policy problem. His notes seize on the “paradox of land” — the gulf between $64,800-an-acre superstar land and $6,700-an-acre small-metro land — as “a huge buying opportunity… if you have a formula / strategy for increasing the value of that land,” the seed of his Alternative Real Estate idea. Clustering also frames his answer to Florida’s crisis: deliberately designed Micro Cities over Suburban Sprawl or Mega Cities of inequality, and the recognition (per Florida) that “not everyone who works in a superstar city has to live in one” — pointing toward The New City / Prosperable and the EPCOT hub-and-spoke model. He also flags the constraint that “New Urban Luddites” who block development throttle the very clustering that drives growth.

Context: “Clustering” is the popular term for agglomeration economies — the productivity and innovation gains that arise when firms and skilled workers concentrate geographically. It is a long-standing idea in urban and economic geography; Florida’s contribution in The New Urban Crisis is to argue that the same force simultaneously generates growth and entrenches spatial inequality.

Where this appears

• The New Urban Crisis — clustering is the book’s central mechanism: “at once the main engine of economic growth and the biggest driver of inequality,” underpinning the land paradox, the micro-cities answer, and the zoning/transit policy agenda Kyle annotates throughout.
