220 million Americans crowd together in the 3% of the country that is urban. 35 million people live in the vast metropolis of Tokyo, the most productive urban area in the world. The central city of Mumbai alone has 12 million people, and Shanghai almost as many. We choose to live cheek by jowl, in a planet with vast amounts of space. Yet despite all of the land available to us, we choose to live in proximity to cities. Using economics to understand this phenomenon, the urban economist uses the tools of economic theory and empirical data to explain why cities exist and to analyze urban issues such as housing, education, crime, poverty and social interaction. Drawing on the success of his Lindahl lectures, Edward Glaeser provides a rigorous account of his research and unique thinking on cities. Using a series of simple models and economic theory, Glaeser illustrates the primary features of urban economics including the concepts of spatial equilibrium and agglomeration economies. Written for a mathematically inclined audience with an interest in urban economics and cities, the book is written to be accessible to theorists and non-theorists alike and should provide a basis for further empirical work.

When firms and people are located near each other in cities and in industrial clusters, they benefit in various ways, including by reducing the costs of exchanging goods and ideas. One might assume that these benefits would become less important as transportation and communication costs fall. Paradoxically, however, cities have become increasingly important, and even within cities industrial clusters remain vital. Agglomeration Economics brings together a group of essays that examine the reasons why economic activity continues to cluster together despite the falling costs of moving goods and transmitting information. The studies cover a wide range of topics and approach the economics of agglomeration from different angles. Together they advance our understanding of agglomeration and its implications for a globalized world.

One of our great urbanists and one of our great public health experts join forces to reckon with how cities are changing in the face of existential threats the pandemic has only accelerated Cities can make us sick. They always have—diseases spread more easily when more people are close to one another. And disease is hardly the only ill that accompanies urban density. Cities have been demonized as breeding grounds for vice and crime from Sodom and Gomorrah on. But cities have flourished nonetheless because they are humanity’s greatest invention, indispensable engines for creativity, innovation, wealth, and connection, the loom on which the fabric of civilization is woven. But cities now stand at a crossroads. During the global COVID crisis, cities grew silent as people worked from home—if they could work at all. The normal forms of socializing ground to a halt. How permanent are these changes? Advances in digital technology mean that many people can opt out of city life as never before. Will they? Are we on the brink of a post-urban world? City life will survive but individual cities face terrible risks, argue Edward Glaeser and David Cutler, and a wave of urban failure would be absolutely disastrous. In terms of intimacy and inspiration, nothing can replace what cities offer. Great cities have always demanded great management, and our current crisis has exposed fearful gaps in our capacity for good governance. It is possible to drive a city into the ground, pandemic or not. Glaeser and Cutler examine the evolution that is already happening, and describe the possible futures that lie before us: What will distinguish the cities that will flourish from the ones that won’t? In America, they argue, deep inequities in health care and education are a particular blight on the future of our cities; solving them will be the difference between our collective good health and a downward spiral to a much darker place.

This book contains the complete text of the special Golden Anniversary issue of the flagship journal of the Regional Science Association International (RSAI), Papers in Regional Science (Volume 83, Number 1), as well as the full text of Walter Isard's Presidential Address "The future (near and far) of regional science". Professor Isard originally delivered the speech in a special plenary session of the fiftieth North American Meetings of the Regional Science Association International. The session began with a ceremonial kickoff to the year-long celebration of the multidisciplinary field's first 50 years. At the ceremony, held on the morning of Friday, November 21,2004 at the DoubleTree Hotel in Philadelphia, we presented Walter Isard, the founder of our multidisciplinary field, as well as Antoine Bailly, the President of the Regional Science Association International, and David Boyce, the Association's Archivist, with commemorative first copies of the anniversary issue. This book, entitled Fifty Years of Regional Science, consists of a compendium of "thought" papers authored by a representative sampling of some of the field's leading scholars. For the special journal issue we originally titled the collection: "The Brightest of Dawns".

The new Handbook of Regional and Urban Economics: Cities and Geography reviews, synthesizes and extends the key developments in urban and regional economics and their strong connection to other recent developments in modern economics. Of particular interest is the development of the new economic geography and its incorporation along with innovations in industrial organization, endogenous growth, network theory and applied econometrics into urban and regional economics. The chapters cover theoretical developments concerning the forces of agglomeration, the nature of neighborhoods and human capital externalities, the foundations of systems of cities, the development of local political institutions, regional agglomerations and regional growth. Such massive progress in understanding the theory behind urban and regional phenomenon is consistent with on-going progress in the field since the late 1960's. What is unprecedented are the developments on the empirical side: the development of a wide body of knowledge concerning the nature of urban externalities, city size distributions, urban sprawl, urban and regional trade, and regional convergence, as well as a body of knowledge on specific regions of the world—Europe, Asia and North America, both current and historical. The Handbook is a key reference piece for anyone wishing to understand the developments in the field.

The authors show how a common approach that emphasizes the three-way interaction among increasing returns, transportation costs, and the movement of productive factors can be applied to a wide range of issues in urban, regional, and international economics. Since 1990 there has been a renaissance of theoretical and empirical work on the spatial aspects of the economy—that is, where economic activity occurs and why. Using new tools—in particular, modeling techniques developed to analyze industrial organization, international trade, and economic growth—this "new economic geography" has emerged as one of the most exciting areas of contemporary economics. The authors show how seemingly disparate models reflect a few basic themes, and in so doing they develop a common "grammar" for discussing a variety of issues. They show how a common approach that emphasizes the three-way interaction among increasing returns, transportation costs, and the movement of productive factors can be applied to a wide range of issues in urban, regional, and international economics. This book is the first to provide a sound and unified explanation of the existence of large economic agglomerations at various spatial scales.
