The Economy of Cities (Vintage) [マスマーケット]

The title of this book is slightly misleading, because the thesis of the book is that cities play an essential role in the process of economic development. Although its anecdotal style gives this book a disarmingly unsystematic appearance, this is a profound book. It is easily one of the most important books written during the 20th century. Economic development is something about which conventional marginal utility economics has very little to say. The Economy of Cities, therefore, fills a kind of void. It stands to conventional economics in much the same position as quantum physics stands to classical physics.

A simply wonderful book.

This book is almost as good as Jacobs' must-read classic, The Death and Life of Great American Cities. Whereas Death and Life deals more with how to foster vitality in individual city neighborhoods, this work deals with the broad importance of thriving urban areas. Here Jacobs gives the reader an understanding of how economically healthy and diverse urban areas are essential to creating healthy economies in general - and more than that, to ultimately creating a healthy global economy. Her ideas fly in the face of much conventional wisdom. But I think she proves the essence of her case with pages of compelling, reasoned argument.

Most reformers, many of whom start out with earnest good intentions, end up wreaking havoc and plunging their countries into tyranny because they attack their countries' economic problems from the wrong end. Most reformers in recent history, from Pancho Villa, through Stalin and Mao, down to current day missionaries - set out to "help" struggling economies by first digging into the dirt of the poorest rural areas. They assume that change must start in the agricultural sector. So they reapportion land; they attempt to introduce modern technology to subsistence farmers; they establish schools, clinics, and communal wells in the rural areas. But often, these efforts come to naught. Indeed they frequently backfire and leave area residents worse off than before.

A typical scenario of the type Jacobs cites - a volunteer worker sets up a well in a parched rural area of some Third World country. But soon after the volunteer leaves, a valve in the well breaks. And there is no way for local residents to get a replacement valve. There is no nearby urban industry to supply valves or any other replacement parts for anything. So the well stagnates, becomes a breeding ground for mosquitoes and a hazard.

Jacobs illustrates why these good will projects so often fail. There is no surrounding urban industry to back them up, to supply all the quirky, often small but oh-so-necessary parts to rural endeavor. Urban areas are also necessary as markets for rural produce. Without recourse to diverse urban economies, virtually all rural areas will fail to thrive in the long run, no matter how much charitable reform is pumped into them.

Jacobs goes further. She illustrates how the very idea of agriculture, as well as most advances in agricultural technique likely STARTED in denser urban areas. This is the most controversial, frequently contested idea in her book. Most people are geared to dismiss urban areas as being devoid of "nature. But the reverse is actually true. There is often more flora, more planting activity, more wildlife and domestic animal husbandry, more agricultural cross-fertilization of all kinds going on in cities than in rural areas. But because the city is by definition "urban," people don't see it and continue to feel they must escape to rural areas in order to experience nature.

However, even if you are of this frame of mind, and if you therefore trip on Jacobs' early contentions about the primacy of cities - I urge you to keep reading. You may not end up being completely convinced, but you will come away with a new tool kit of ideas that you can apply in a myriad of ways as a citizen of the world.

Any politician who will have to make decisions touching on the national or global economy should definitely read this book. Everyone from well-intentioned celebrity reformers down to individuals who simply send a few dollars a month to Guatemalan waifs should read this book, and learn how they might redirect some of their future contributions into more sustainable projects. Every voter should read this book. It's a well-written, interesting book that gives insights into how an economy can develop and diversify into vitality. It suggests definite solutions. In short, it's a book for everyone.

This book has some great insights but is getting a bit outdated. I thought the section on the origin of agriculture was fascinating stuff, but I'd like to know how Ms. Jacobs' theories square with recent research.

The comparison of Manchester and Birmingham was great. I think Ms. Jacobs is basically correct with her analysis of what it takes to make a vibrant, prosperous city. Her basic recommendations for city layout--small, short blocks, high concentrations of people walking, a mix of buildings of various types and ages--are very good. She is right on point with her criticism of urban renewal programs and freeways.

Ms. Jacobs' analysis of how business development occurs is fun to read and very relevant to today. She makes it very clear that rural towns that try to develop by attracting a local assembly plant or the like for a large company are barking up the wrong tree.

The book has some problems. Ms. Jacobs dismisses problems with resource depletion far too easily as the product of a stagnant economy. She also dismisses population growth, seeing it as a symptom of a growing economy, not a problem. There is of course some truth to this, but in my opinion migration is perfectly adequate to take care of local labor shortages. The side effects of nationwide and worldwide population growth are too severe to be treated lightly as Ms. Jacobs does.
