Book excerpt: Los efectos positivos y negativos de la aglomeración de la población y el empleo son más fuertes en las ciudades que en cualquier otro lado. Las externalidades medio ambientales negativas y sus efectos en la calidad de vida de la población, -en otras palabras, la sostenibilidad urbana-, están tomando mayor importancia en los temas principales de discusión en la Economía Urbana. Cada vez un número mayor de estudios confirma que dichas externalidades dependen de las características funcionales y la organización espacial de las áreas urbanas El policentrismo es la estructura urbana espacial en la que coexiste más de un centro de empleo, es decir, aglomeraciones relevantes de actividad económica. Al policentrismo, se le ha asociado teóricamente la ventaja de permitir distancias entre los lugares de residencia de los trabajadores y los de la actividad económica más cortas. No obstante, hay trabajos que muestran que los efectos de la forma y la estructura espaciales urbanas en las pautas de suelo y movilidad pueden diferir según sean las condiciones económicas, sociales y demográficas de la población. Así pues, mientras que en las ciudades de los países desarrollados las periferias son menos densas y más ricas que las áreas centrales; en los países en desarrollo, las periferias son mayoritariamente las áreas más densas y pobres de las ciudades. "Cities in developing countries are both important and problematic realities, being the recipient of rural unemployment for a long time, and thus locus where the rural crisis generates its negative effects: poverty, social tensions and social disease, high income inequalities, natural resources scarcity, environmental decay: they all mirror unprecedented and dramatic appearances, concentrated in particular territorial settings, and call for particular attention in spatial economic analysis" (Capello & Nikjamp, 2005: 3). En este escenario, la MAMV es un caso de estudio relevante. De un lado su estructura espacial ha estado evolucionando de un monocentrismo fuerte, a un policentrismo cuando menos incipiente. Detrás de esta evolución, se hallan un largo proceso de descentralización de la población durante la última mitad del siglo pasado y un intenso proceso de descentralización del empleo ocurrido en el último par de décadas. Por otro lado, el área metropolitana y especialmente la Ciudad de México, se halla en el top tres del ranking de ciudades más pobladas y grandes del mundo. Finalmente, también se la reconoce como una de las ciudades con los más altos niveles de congestión y de contaminación atmosférica en todo el globo, hasta generar la idea de que el sistema de transporte público en la ciudad está colapsando. El objetivo principal de la tesis es responder a la cuestión de en qué medida los subcentros de empleo influyen en la pauta de uso del suelo y de commuting. Los objetivos particulares, según se fueron abordando dichas cuestiones en cada capítulo, son analizar la relación entre la estructura espacial o la forma espacial urbana con la pauta de usos de suelo y la pauta de commuting, así como la pauta de emisiones de GEI en la MAMV. De este modo, indirectamente intentamos responder a la cuestión de qué tanto la planeación urbana relacionada con el modelo de desarrollo urbano policéntrico puede ser un mecanismo para aliviar las externalidades negativas de la aglomeración de la población y de la actividad económica. En la tesis tratamos dos retos empíricos. Primero, intentamos tener en cuenta los problemas de endogeneidad que por la estructura de los datos es relevante en la identificación del efecto de las variables de estructura y forma espaciales urbanas sobre las pautas de uso de suelo y de commuting. Y segundo, pocos estudios abordan el efecto neto de cada tipo de variables, de las variables de estructura urbana espacial por un lado y de las variables de forma urbana por otro. Aunque como señalamos puntualmente hay aún cuestiones pendientes sobre ambos temas econométricos.

Available in PDF, EPUB and Kindle. Book excerpt: In any country the options for national urban and spatial development must be reviewed in light of the present urban system and spatial structure. This book aims to interpret urban and spatial development in Mexico from the pre-industrial era into the third quarter of the twentieth century. The book is divided into three parts, with an introductory chapter on the conceptual framework of the study. Part one describes the development of the modern urban system. Part two describes the structure of the modern urban system. Part three discusses the issues arising from the urban and spatial structure and reviews some of the options that might be considered in formulating a future urban and spatial strategy. Although the study is concerned specifically with Mexico, it is relevant for other countries in which similar problems will undoubtedly become increasingly urgent.

Book excerpt: One of New York Magazine's best books on Silicon Valley! The true, behind-the-scenes history of the people who built Silicon Valley and shaped Big Tech in America Long before Margaret O'Mara became one of our most consequential historians of the American-led digital revolution, she worked in the White House of Bill Clinton and Al Gore in the earliest days of the commercial Internet. There she saw firsthand how deeply intertwined Silicon Valley was with the federal government--and always had been--and how shallow the common understanding of the secrets of the Valley's success actually was. Now, after almost five years of pioneering research, O'Mara has produced the definitive history of Silicon Valley for our time, the story of mavericks and visionaries, but also of powerful institutions creating the framework for innovation, from the Pentagon to Stanford University. It is also a story of a community that started off remarkably homogeneous and tight-knit and stayed that way, and whose belief in its own mythology has deepened into a collective hubris that has led to astonishing triumphs as well as devastating second-order effects. Deploying a wonderfully rich and diverse cast of protagonists, from the justly famous to the unjustly obscure, across four generations of explosive growth in the Valley, from the forties to the present, O'Mara has wrestled one of the most fateful developments in modern American history into magnificent narrative form. She is on the ground with all of the key tech companies, chronicling the evolution in their offerings through each successive era, and she has a profound fingertip feel for the politics of the sector and its relation to the larger cultural narrative about tech as it has evolved over the years. Perhaps most impressive, O'Mara has penetrated the inner kingdom of tech venture capital firms, the insular and still remarkably old-boy world that became the cockpit of American capitalism and the crucible for bringing technological innovation to market, or not. The transformation of big tech into the engine room of the American economy and the nexus of so many of our hopes and dreams--and, increasingly, our nightmares--can be understood, in Margaret O'Mara's masterful hands, as the story of one California valley. As her majestic history makes clear, its fate is the fate of us all.

Download or read book Cities of Knowledge written by Margaret O'Mara and published by Princeton University Press. This book was released on 2005 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the magic formula for turning a place into a high-tech capital? How can a city or region become a high-tech powerhouse like Silicon Valley? For over half a century, through boom times and bust, business leaders and politicians have tried to become "the next Silicon Valley," but few have succeeded. This book examines why high-tech development became so economically important late in the twentieth century, and why its magic formula of people, jobs, capital, and institutions has been so difficult to replicate. Margaret O'Mara shows that high-tech regions are not simply accidental market creations but "cities of knowledge"--planned communities of scientific production that were shaped and subsidized by the original venture capitalist, the Cold War defense complex. At the heart of the story is the American research university, an institution enriched by Cold War spending and actively engaged in economic development. The story of the city of knowledge broadens our understanding of postwar urban history and of the relationship between civil society and the state in late twentieth-century America. It leads us to further redefine the American suburb as being much more than formless "sprawl," and shows how it is in fact the ultimate post-industrial city. Understanding this history and geography is essential to planning for the future of the high-tech economy, and this book is must reading for anyone interested in building the next Silicon Valley.
