Chapter Eight - Changes with future ICT technologies and future studies

Abstract

This book has addressed land use regulations, disentangling complex mechanisms of the dependency between spatial externalities and land use regulations theoretically, and derives practical ways for optimizing them. Each chapter explores a different situation in a city to illustrate the mechanisms. Chapter 2, assuming a closed two discrete city model, shows the necessity for minimum and maximum FAR regulations to maximize social welfare. Chapter 3 explores the difference in optimal regulation between an open city and a closed city. Chapter 4 targets a growing city with congestion. Chapter 5 addresses a city with agglomeration economies and transport congestion. Chapter 6 introduces cordon pricing in a city with land use regulation. These chapters show that a second-best situation has different regulations because distortions can depend on land use regulations differently. This final chapter first discusses a different situation that can arise in the future. Information and communication technology (ICT) has drastically changed our life. By virtue of the fast-improving rate of ICT, at this rate, our society will soon change to a totally different society. ICT is expected to drastically reduce the supply-side cost in many situations and to produce convenient life.
