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.

Covering a wide range of aspects surrounding economic integration in East Asia, this well-researched text will appeal to undergraduate and postgraduate students of development studies, regional economics and Asian studies. It will be of particular value to those on courses concerned with economic and regional integration.

Economic Integration in East Asia addresses these issues from the perspectives of both spatial and neoclassical economics. As the book highlights, if the regional disparities continue to grow, this may constitute a fatal obstacle to deepening integration and the growth potential of East Asia.

With its focus firmly on recommendations for the future, this book will be of great interest to academics and researchers of development, Asian studies and economic geography as well as development specialists in government and international organizations involved in East Asian integration.

The central theme of this book is national land and infrastructure design in the age of the declining population and the recovery from the Great East Japan Earthquake in the affected regions in Japan. Based on the theory of spatial economics and evidence from Japanese history, the authors show that the growing economy with a population increase develops into a multi-cored and complex structure. In the population decline phase, however, such construction will be destabilized because of agglomeration economies in the central core. Then, a catastrophic shock that strikes may provoke the decline of the lower-rank-size provincial cities and their eventual disappearance if they compete  only in lower prices of staple products. Not only is the practice bad for the residents; it also leads to lower national welfare resulting from the loss of diversity and overcrowded big cities. The authors argue that small local towns can recover and will be sustained if they will endeavor in innovative production by making good use of local natural resources and social capital. Under the ongoing declining population in Japan, an undesirable concentration in Tokyo will proceed further with increasing social cost and risk. The recent novel coronavirus pandemic has highlighted that concern.
