This book outlines the core concept of the theory of mixed oligopoly and presents recent results that have arisen in a mixed oligopolistic market. The wave of privatization since the 1980s has taken the development of the theory of mixed oligopoly in several directions. Although the main concern of the theory of mixed oligopoly focuses on the effect of regime change-especially privatization of a public firm-on social welfare, existing studies have not considered the difference in economic environments. With drastic changes in economic environments along with economic development in recent years, the domestic and foreign markets have become more and more integrated, firms have become concerned about corporate social responsibility, and governments or politicians have had various interests and preferences. Against that background, this book revisits the question of how privatization affects social welfare by incorporating regional and international interdependency and investigates how firms' activities for corporate social responsibility, governments' preferences, and political economic situations affect the market circumstance in a mixed oligopoly. The dynamic aspect of privatization is also investigated.

This book gives readers advanced insights into macroeconomics with historical perspectives and proposes policies to resolve the problems the Japanese economy faces. In the past decade, Japan has experienced a rapidly aging population with an ever-decreasing number of children. This causes significant problems related to macroeconomics covered by this book: a decreasing population, an increasing public debt, an increasing social security expenditure, and deteriorating labor productivity. Thus, the government must change the course it has followed until now. These problems can be categorized into two types: (1) human capital and (2) political institutions. The book therefore consists of two parts. The first, using a macroeconomic model, is mainly a discussion of health and education problems related to human capital. The second part deals with policy problems related to political institutions, that is, the intergenerational imbalance, preventive medicine, local public utilities, and other political issues. Through the arguments presented here, readers gain knowledge that will help to achieve the necessary economic policies in Japan.

This book introduces recent developments in both theoretical and empirical analyses of local public economics. Theories of those economics as well as empirical analyses have been developed dramatically in various directions in recent years. One direction has been to reflect real economic circumstances, especially in Japan. In the early 2000s, Japan experienced the so-called great merger (or consolidation) of municipalities in the Heisei era (1999 through the present), with the number of municipalities shrinking from 3,232 to 1,821 for increasing administrative and financial efficiency. This phenomenon is mainly due to a drastic change in demography in Japan: the dimishing birthrate and aging population. Following the consolidation, regional coordination has been undertaken to raise overall administrative and financial efficiency. In sum, various types of public policies for tackling the decreasing birthrate and aging population have been carried out. Urban sprawl and the timing of municipal mergers are dealt with from a broad point of view, and public child care services and tax competition are investigated from a policy standpoint. Another direction has been to incorporate new ideas for forming theoretical frameworks for local public finance, most of which have been based on static situations. In the recent trend toward globalization, local governments have attended not only to the welfare of residents but also to the interests of regional economic development. In addition, decision making by local governments has tended to be affected by political activities. Thus, the endogenous growth setting and lobbying activities for the activities of local governments are discussed in the book. With these new directions for analyses, the author tackles the topics of tax competition, cross-border shopping, local provision of public goods, and soft budgets, thus covering a broad range of aspects of local public finance.
