We study decentralized and optimal urbanization in a simple multi-sector model of a rural-urban economy focusing on productivity differences and internal trade frictions. We show that even in the absence of the typical externalities studied in the literature, such as agglomeration, congestion or public goods, the decentralized city size can be either too large or too small relative to that chosen by a planner. In particular, optimal urbanization exceeds decentralized levels when productivity differences in location specific non-traded goods is small, a case typically arising in developed economies. In contrast, developing countries are likely to display overurbanization. A numerical exercise calibrated to Brazilian data suggests that the wedges can be quantitatively important. Urban biased policies - placing a higher weight on the welfare of city dwellers - are closer to optimal policies than decentralized allocations whenever productivity differences in non-traded sectors are either very small or very large. For intermediate productivity differences, the urban bias leads to larger cities even relative to decentralized policies.

Urbanization refers to a process in which an increasing proportion of an entire population lives in cities and the suburbs of cities. Historically, it has been closely connected with industrialization. When more and more inanimate sources of energy were used to enhance human productivity (industrialization), surpluses increased in both agriculture and industry. Larger and larger proportions of a population could live in cities. Economic forces were such that cities became the ideal places to locate factories and their workers. This new book presents recent and significant research from around the globe.

Based on a discussion of conflicts in the urbanization process, this book provides theoretical and practical solutions for the preservation and development of urban localities. On the basis of informative case studies, it reveals the similarities and unique aspects of urbanization in Germany and China. The process of urban growth and the future trend of locality and urbanization are also examined. The book gathers contributions from architects, landscape designers, environmental engineers, urban planners and geographers, who analyze urban issues from their individual perspectives and provide methods for preserving and developing urban localities. As such, it expresses responses to urban development trends against the backdrop of sustainability in the 21st century.
