Advances in Japanese Business and Economics – serie

Symmetry and Economic Invariance (second enhanced edition) explores how the symmetry and invariance of economic models can provide insights into their properties. Although the professional economist of today is adept at many of the mathematical techniques used in static and dynamic optimization models, group theory is still not among his or her repertoire of tools. The authors aim to show that group theoretic methods form a natural extension of the techniques commonly used in economics and that they can be easily mastered. Part I provides an introduction that minimizes prerequisites including prior knowledge of group theory. Part II discusses recent developments in the field.

Developments of International Trade Theory offers the life-long reflections of a distinguished Japanese scholar who pioneered the application of general equilibrium theory to international trade. Written in a style that makes it easily accessible to scholars and students, the book combines standard topics on international trade with a discussion of the evolution of the theory and as well as recent discussions on topics such as immiserizing growth.This book consists of two parts. Part I examines the historical progression of international trade theory, and Part II addresses the modern theory and recent developments of international trade. In this way the book offers a comprehensive evaluation of the non-monetary problems of international economics.Taking advantage of the publication of this new edition, the author includes two new chapters, “Adam Smith and Disequilibrium Economic Theory” and “Complete Specialization in Classical Economics,” which readers will profit from reading after they have studied the basic theories of international trade in the main part of the book.

This book aims to explain to the readers the basic idea of the general equilibrium theory, which forms the core of the current mainstream economics called neoclassical school. To understand this theory is absolutely necessary, either to study further or to criticize the contemporary economic theories. The author not only explains traditional theories, but also makes clear the many problems which are still unsolved.As a text book or reference book for those students who are studying microeconomics for the first time, the author recommends the use of Chapter 1, Chapter 2 (except section 9), Chapter 3 (from section 1 to section 3, section 6, section 11), Chapter 4 (from section 1 to section 4), Chapter 5 (from section 1 to section 5, section 8), Chapter 6 (except sections 6 and 7), Chapter 7 (from section 1 to section 5), Chapter 8 (from section 1 to section 6) and Chapter 9 (sections 1, 4 and 7). For more advanced readers, the author recommends the remaining sections and the literature recommended in the last part of each chapter. Problems given at the end of each chapter allow readers to confirm understanding of the content of the chapter and suggest to the readers more advanced studies. Incidentally, the author tried to avoid the use of the advanced mathematics. Only elementary knowledge of differential calculus and linear algebra are required to read this book.

Despite the globalization of accounting standards occurring through convergence to International Financial Reporting Standards, local accounting systems are deeply intertwined with each country’s unique institutions such as its corporate system, disclosure practices and enforcement mechanisms. First, this book empirically analyzes the effects of globalization and localization of accounting rules on corporate behavior such as earnings management, signaling, investment behavior and dividend payout policy. Second, the book unravels the economic consequences of disclosure based on the concept of self-disciplining enforcement such as management forecasts, environmental disclosures and risk disclosures by Japanese firms. This volume is a step forward in understanding the link between accounting and corporate behavior based on a new institutional accounting approach.

This book investigates the reasons for persistent public deficits and delayed fiscal reform in Japan, placing a special emphasis on political economy aspects. Japan is confronted with the need to pursue fiscal discipline for fiscal consolidation and implement structural reforms for reorganizing fiscal expenditures. Focusing on particular policy fields including social security, female labor supply, public works, and intergovernmental transfer schemes, the book clarifies economic and political elements that have hindered effective steps toward these two goals. Facing population aging and a business downturn, the Japanese government was urged to increase social security expenditures and the budget for Keynesian stimulus policies. As elucidated in the book, the institutional design has worked to over-represent the demands of elderly generations and local interest groups and to expand these expenditures. Rigorous theoretical and numerical analyses reported throughout the book consequently provide readers with insights into incentive designs and institutional reforms necessary for fiscal consolidation, also presenting points of view for public policy and public debate.

This book reconstructs Keynesian macroeconomics so that it is compatible with the neoclassical dynamic microeconomic theory. This theory adopts three postulates: rational expectations, perfect price flexibility, and exclusion of the money in utility function (MIU). Based on the new theoretical finding that the Lucas model (1972) contains multiple equilibria, the author unifies Keynesian and monetarist theories within the same framework. The book applies the above basic theory to international macroeconomics and economic growth theory.New Keynesian theory contains logical inconsistencies: menu costs that have no close relationship with microeconomics and MIU, which implies that the money accumulated as wealth is never spent. These two assumptions do not proximate the real world. In this volume, the author discusses how various segregated theoretical approaches in macroeconomics relate to one another and proposes how to integrate them.

This book is one of the first comprehensive works to fill the knowledge gap resulting from the limited number of empirical studies on interfirm networks. The in-depth empirical research presented here is based on a massive transaction relationship database of approximately 400,000 Japanese firms. This volume, unlike others, focuses on the role of interfirm networks in three different fields: (1) macroeconomic activities, (2) economic geography and firm dynamics, and (3) firm–bank relationships. The database for this work is constructed in collaboration with Japan's largest credit research company, Teikoku Data Bank, and covers a substantial portion of Japanese firms with information on firms' transaction partners, shareholders, financial institutions, and other attributes, including their locations and performance.Networks prevail in many aspects of economic activities and play a major role in explaining a wide variety of economic phenomena from business cycles to knowledge spillovers, which has motivated economists to produce a number of excellent works.  In the policy arena, there has been a growing concern on the vulnerabilities of networks based on the casual observation that idiosyncratic shocks on firms can be amplified through inter-firm connections and leads to a systemic crisis. Typical examples are the manufacturing supply-chain networks in the automobile and electronics industries which propagated regionally concentrated shocks (the Great East Japan Earthquake and floods in Thailand in 2011) into global ones. An abundance of theoretical literature on the formation and functions of networks is available already.This book breaks new ground, however, and provides an excellent opportunity for the reader to gain a more integrated understanding of the role of networks in the economy. The Economics of Interfirm Networks will be of special interest to economists and practitioners seeking empirical and quantitative knowledgeon interfirm and firm–bank networks.

Over the past two decades, the issue of equilibrium indeterminacy has been one of the major research concerns in macroeconomic dynamics. Growth and Business Cycles with Equilibrium Indeterminacy discusses the main topics in this literature. Based on comprehensive surveys and the author’s original research, this book explores sunspot-driven fluctuations in real business cycle models, multiple equilibria in endogenous growth models, and the stabilization effects of fiscal and monetary policy rules.  The book also considers equilibrium indeterminacy in open economy models.

Based on recent advances in economics, especially those in behavioral economics, this book elucidates theoretically and empirically the mechanism of time-inconsistent decision making that leads to various forms of self-destructive behavior. The topics include over-eating and obesity, over-spending, over-borrowing, under-saving, procrastination, smoking, gambling, over-drinking, and other intemperate behaviors, all of which relate to serious social problems in advanced countries.In this book, the author attempts to construct a bridge between the basic theory of time discounting, especially as of hyperbolic discounting, and empirically observed “irrational (non-classical)” behavior in the various contexts just mentioned. The empirical validity of the theory is discussed using unique micro data as well as public macro data. The book proposes prescriptions for individual decision makers, whether sophisticated or naïve, to make better choices in self-control problems, and also provides policy makers with useful advice for influencing people’s decision making in the right directions. This work is recommended not only to general readers who seek to learn how to attain better self-regulation under self-control problems. It also helps researchers who seek an overview of positive and normative implications of hyperbolic discounting, and thereby reconstruct economic theory for a better understanding of actual human behavior and the resulting economic dynamics.

This book develops new, original methods of welfare comparison and comparative dynamics between distinct and discretely positioned (rather than continuously related) socioeconomic situations. These methods are not only realistic but also extremely relevant to serious economic problems. Using them, the book sheds illuminating new light on the theoretical analysis of Keynesian economics and other important issues of political economy. For instance, it shows that the principle of effective demand applies exactly as Keynes put it to the unemployment equilibrium in the short run. It also shows that the equilibrium may change along the expansion path as the government chooses to vary its expenditure to maximize national welfare. The same methods are effectively employed theoretically to investigate modern trade policy issues such as gains from trade, the theory of tariffs, free trade agreements, and the role of the WTO. Those methods are also used to study the welfare and efficiency of various socioeconomic situations.

This book, based on economics and game theory, analyzes the changes that Japan is now facing as a reflection of changes in Japanese families and society. The author presents a simple framework for the structural relationship among markets, communities including families, and the state; and uses it to explain the changes that have occurred in Japanese society. Social changes have created a series of social problems such as population ageing, poverty, and regional disparities, which require changes in public policies. The book provides readers with rich information about the Japanese social security system, social policies and regional policies by explaining why they are developed, how they are designed, and what challenges they face. Readers will find that the transformation of Japanese society is not really a special case but a fairly common one that many developed countries have experienced and many developing countries are going to experience. The book will be useful not only to those who are interested in Japanese society and public policies but also to anyone who is interested in the transformations of families, communities, and roles of the state in a modern market economy.

This book answers the question of how exactly property price indexes should be constructed.The formation and collapse of property bubbles has had a profound impact on the economic administration of many nations. The property price bubble that began around the mid-1980s in Japan has been called the 20th century's biggest bubble. In its aftermath, the country faced a period of long-term economic stagnation dubbed the "lost decade." Sweden and the United States have also faced collapses of property bubbles in the 20th and early 21st centuries, respectively.It has been pointed out that the "information gap" that existed between policy-making authorities and the property (including housing) and financial markets was a problem. In 2009, the IMF proposed the creation of a housing price index to the G20 in order to fill this information gap, and the proposal was adopted. Furthermore, in 2011, it was suggested that the next economic crisis would be caused by a bubble incommercial property prices, and it was decided to create a commercial property index as well.This book provides practical examples of how the theory of property price indexes can be applied to the issues of property as a non-homogenous good and a technological and environmental change.

This monograph is devoted to the analysis of the dynamics of business cycles and stabilization policies. The analysis is conducted in models of the AS-AD type, focusing on involuntary unemployment and capital accumulation. Major conclusions are the following. (1) Sectoral imbalances, once emphasized by such business-cycle theorists as K. Marx, A. Spiethoff, and F.A. Hayek, are rectified in finite time by competitive investment allocation, leaving aggregate variables as the main variables of business cycle dynamics. (2) The chronology of events during a cycle is established, which resolves the so-called real wage puzzle. (3) Owing to the crowding-out effect on investment, fiscal stabilization policies can destabilize the business cycle dynamics if implemented too intensively. (4) If coordinated properly, monetary stabilization policies can remove the destabilizing tendency of fiscal stabilization policies.

This book reappraises the Japanese employment system, characterized by such practices as the periodic recruiting of new graduates, lifetime employment and seniority-based wages, which were praised as sources of high productivity and flexibility for Japanese firms during the period of high economic growth from the middle of the 1950s until the burst of bubbles in the early 1990s. The prolonged stagnation after the bubble burst induced an increasing number of people to criticize the Japanese employment system as a barrier to the structural changes needed to allow the economy to adjust to the new environment, with detractors suggesting that such a system only serves to protect the vested interests of incumbent workers and firms. By investigating what caused the long stagnation of the Japanese economy, this book examines the validity of this currently dominant view about the Japanese employment system. The rigorous theoretical and empirical analyses presented in this book provide readers with deep insights into the nature of the current Japanese labor market and its macroeconomic impacts.

This book explores the linkages between the evolution of corporate social responsibility (CSR) and corporate financing and governance in Japan since the late 2000s. Since the 1990s, increasing economic and financial globalization has steadily eroded the Japanese style of business based on relationships and influenced the awareness and practices of CSR that are unique to Japanese companies. In Japan’s two “lost decades” after the bubble economy, the business model and corporate financing seem to have continued a gradual financial reform toward a more market-oriented system. CSR awareness and practices of Japanese companies have been influenced by social and environmental issues that global society and communities face. Furthermore, the Fukushima nuclear accident in 2011 triggered increasing attention paid to the responsibility of business toward society. In this process, major players in corporate governance and components of governance structure have continued to change. The conventional view of Japanese corporate governance and corporate finance is too narrow to understand this field in Japan. This book is based on empirical research to investigate how multifaceted CSR has aligned with business and finance and has influenced the corporate governance structure of Japanese companies. The findings and discussions in this book act are stepping stones in further research on the linkages between business and society, and provide empirical evidence on changes in Japanese corporate finance and governance.

This book is the first book that provides comprehensive economic analysis of cross-border outsourcing by Japanese manufacturing firms based on microdata. Previous literature on many other countries has often been constrained by limited data availability about outsourcing, but research contained in this book exploits unique firm-level data and directly tests theoretical hypotheses derived from new firm heterogeneity trade models. Productivity, capital–labor ratio and R&D intensity are examined at the firm level. While rich empirical results in this book convince us how powerful the orthodox economic theory is in understanding Japanese firms, detailed firm-level findings, combined with accessible and concise overviews of Japanese international trade, are widely informative for international economists, experts of Japanese society, business strategists for offshoring, and policy makers in both developed and developing economies. This book further discusses how boundaries of Japanese firms, traditionally sheltered by language and cultural barriers, are affected by outsourcing decisions simultaneously crossing national borders and firm boundaries. The interpretations of Japanese characteristics in outsourcing have deep implications for understanding drastically changing Japanese business amid globalization.

This book addresses essential questions about housing by building theoretical models based on various real world problems in Japan and testing these models using econometric methods. Almost all related empirical analyses use Japanese household longitudinal data. Accordingly, the author analyzes whole aspects of the data, based on an understanding of the actual situation, theory, and empirical analysis, to directly derive a vision of a future housing policy.Why are houses expensive and difficult to obtain in Japan? Why do people have to live in small houses? Why do people not relocate frequently? Why is the earthquake insurance subscription rate so low, particularly in an earthquake-prone country such as Japan, even after such a catastrophic event as the Great East Japan Earthquake of 2011? How do existing housing finance and tax policies or laws relate to these real world problems? To answer these questions, the book clarifies the unique criteria that characterize housing problems in Japan and presents a vision of future housing policy.The short answer is that existing housing finance policy that adopts criteria based on the floor space of houses creates incentives for people to live in even smaller houses. Furthermore, the Japan Rental Act, which affects people renting homes, reduces residential mobility. The incidence of underinsurance against earthquake risk is a result of earthquake insurance market imperfections such as crude and rough geographical risk ratings.The book elaborates on these factors in four parts and will be of interest to all readers who are concerned with the housing market and household behavior in Japan.
