Theregisteredcompanyaddressis:152BeachRoad,#21-01/04GatewayEast,Singapore189721,Singapore Preface In the1980s, the Japaneseeconomy reached its high watermarkof prosperity with its GDP growing at an average annual rate of 4%. However, after the burst of the economic bubble in early 1990s, the Japanese economy entered a long period of stagnation. Since then, its growth rate has been holding at around 1%, repeatedly registering negative growth. This drastic deterioration of economic performance inducedmanypeopletorevisetheirappraisaloftheJapaneseemploymentsystem, characterized by periodic recruitment of new graduates, lifetime employment, and seniority-based wages. Before experiencing the long stagnation, the system had been praised as a source of high productivity and flexibility for Japanese firms. Now, in contrast, it is criticized as a barrier to the structural changes needed to allow the economy to adjust to the new environment, with detractors suggesting thatsuchasystemonlyservestoprotectthevestedinterestsofincumbentworkers and firms. This book theoretically and empirically investigates what caused the long stagnation of the Japanese economy, thereby examining the validity of this cur- rentlydominantviewoftheJapaneseemploymentsystem.Thebookisdividedinto five chapters that are organized as follows (authors of each chapter are in paren- theses).AfteroverviewingrecentdevelopmentsinthestateofJapan’slabormarket in Chap. 1 (by Souichi Ohta and Hiroshi Teruyama), we present two theoretical modelsastheirpossibleexplanationsinChaps.2and3(bothbyAkiomiKitagawa). Then, in Chaps. 4 and 5 (the former by Teruyama and the latter by Ohta and Teruyama), we use Japanese data to examine the empirical validity of our expla- nations. Although different authors have written the individual chapters, the five chapters as a whole provide a unified view of the current state of the Japanese employment system. As they are aimed at professional economics researchers, the analyses presented in this book might be somewhat technical. Nevertheless, we hopethattheywillhelpreadersunderstandthenatureofthecurrentJapaneselabor market and its macroeconomic impacts. Ourresearchprojectbeganinthespringof2007,withAkihisaShibataatKyoto University.Althoughheafterwardfoundhimselftoobusytobecomeacoauthorof this book, there is no part of the book that has not benefited from stimulating v vi Preface discussionwithhim.Inaddition,manyothercolleagueshavehelpedusimprovethe original manuscript, either with specific comments on earlier versions of the chapters or through discussions over the years on some of the covered topics. A nonexhaustive list includes Masahiro Abe, Kenn Ariga, Koichi Futagami, Yuji Genda, Ryo Horii, Ryo Kambayashi, Daiji Kawaguchi, Noritaka Kudoh, Makoto Saito, and Katsuya Takii. Above all, special thanks go to Hiroyuki Toda and Masako Kimurafor permission toquote from theircollaborative work with two of us, thereby contributing to the empirical part of this book. Much of the material found in Chap. 4 is based on Teruyama’s articles coauthored with Hiroyuki Toda. The empirical results in Chap. 5 are obtained through Ohta and Teruyama’s col- laborative research with Masako Kimura. We are also grateful to an anonymous reviewerforusefulcomments(and,ofcourse,forapositiveverdictonpublication). Much of the research underlying this book received the financial support of the Japan Society for the Promotion of Science (JSPS KAKENHI Grant Numbers 19330039, 23330060, 24243035, 24330074, 26285068, and 16H03631), and we would like to acknowledge it.
