Why another book about cities?

city books

The starting point for Jacobs’s analysis and the focus of much of her thought is the city, its nature and significance. There are plenty of books out there that in some way celebrate cities.  Many describe cities as engines of economic development, wellsprings of art and culture, and incubators of ideas religious, social, and scientific.  But few go very far in explaining why and how all that usually happens in a city.  Fewer still view the urban processes as expressions of “emergence,” or what some social theorists describe using the related term “spontaneous order.”  That is the perspective of this book and its main contribution: To look closely at what makes a city a spontaneous order and an engine of innovation, and to trace the analytical and policy consequences of viewing it this way. Jane Jacobs is one of those exceptions, indeed an outstanding one.  In fact, she is probably the first to carefully examine, not only the nature and significance of cities, but to distill realistic principles that govern urban systems and to analyze the mechanisms of economic change that follow from those principles. Her analysis of the relation between the design of public space and social interaction offer insights that complement, and often exceed, those of Max Weber, Henri Pirenne, Georg Simmel (pdf), Kevin Lynch, and others. Her work also has deep connections with modern social theorists such as F.A. Hayek, Elinor Ostrom, Mark Granovetter, and Geoffrey West. But she was not the first to develop conceptual tools congenial to understanding urban processes as emergent, spontaneous orders.  In fact they have largely been available for decades in the field of economics, although few professional economists, including urban economists, have fully appreciated the urban origins of many of their standard concepts and tools of analysis. Indeed, there is a […]

Rothbard The Urbanist Part 6: Traffic Control

Maybe the delay in posts led you to believe the Rothbard Series was complete.  The good news is that there are a few more posts to go, and the ones coming up next should be the most interesting to urbanists. If you haven’t kept up with our discussion, Murray Rothbard’s classic For A New Liberty can be downloaded free from Mises.org as pdf, web page, and audio book read by Jeff Riggenbach, and you can read the first five posts: Rothbard the Urbanist Part 1: Public Education’s Role in Sprawl and Exclusion Rothbard the Urbanist Part 2: Safe Streets Rothbard the Urbanist Part 3: Prevention of Blockades Rothbard the Urbanist Part 4: Policing Rothbard the Urbanist Part 5: Diversity and Discrimination Not long ago, I posted a video from a friend showing one traffic intersection in Cambodia that appears to function well without any signaling.  Here are some other resources on the emergent order of traffic without signals: Econtalk podcast with Mike Munger on Cultural Norms Cafe Hayek: The arc of emergent order and Traffic without Traffic Signals. Kids Prefer Cheese:  Movie from atop the Arc Tom Vanderbilt: News for Traffic Signal Manufacturers Infrastructurist on the Dutch City of Drachten I caught some flak from a commenter who considered it “disingenuous” to present the video of the intersection as evidence “of a workable intersection.”  Of course I had to remind the commenter that I don’t consider these types of intersection something that I advocate as a “free market” solution: Don’t mistake me as an advocate of a world without traffic signals. I am quite certain that some sort of traffic signaling would likely emerge from a free-market street system. But, my bigger point is that when information is dispersed widely among decision-makers without government monopoly, sustainable solutions emerge from the […]

The Nature of the Living City

Sandy Ikeda posted an abstract for a short essay he is contributing to a Festschrift honoring Jane Jacobs.  He quite eloquently describes the nature of the living city: A city is not a man-made thing.  Rather, it emerges from the actions of its inhabitants, who interact in unpredictable yet orderly ways.  Under the right conditions – the right “rules of the game” – what arises is vital, creative, radically unpredictable, and profitable:  the living city. Neither can it be inefficient, because that too presupposes a system-wide plan.  Both efficiency and inefficiency presume that we know how things ought to be, what success and failure look like, and that’s impossible in the urban dynamic.  Instead, borrowing from ecology (and certain heterodox schools of economic thought), we might say that a living city is a “dynamically stable” process, in which the forces of positive and negative feedback, as well as sudden mutation and diversity, combine under the right conditions to generate order through time.  It embodies trial and error, surpluses and shortages, apparently useless duplication, conflict and disappointment, trust and opportunism, and discovery and radical change.  These are in the nature of the living city. Another piece to look forward to!  Sounds like Sandy touches on some similar themes to Mathieu Helie’s upcoming piece on Emergent Urbanism.
