In this book, Professor Tachibanaki investigates the empirical and theoretical issues of wage determination and wage differentials in Japan since the War, concentrating on recent developments. He also examines the relationship between the role of wages and such features of the labour market as employment and unemployment.

Japan's institutional singularities - including what the OECD called the 'Three Sacred Treasures of the Imperial Houses': nenko-joretsu (seniority system), lifelong employment, and enterprise unionism - are investigated on both efficiency and equity grounds.

The Japanese authorities collect a great variety of macroeconomic data, including data relating to the labour market which is categorized according to a large number of demographic variables and firm characteristics. Professor Tachibanaki reports and analyses the data that is publicly available, including the Ministry of Labour's annual Wage Structure Survey of over one million employees, enriching it with his own research observations.

An introduction to the main characteristics of the labour market, industrial relations systems, and wages in Japan, explaining the degree of difference from Europe and the USA, establishes a framework for labour economists relatively new to the study of Japan. Detailed explanations of wage determination according to sex, age, education, experience, occupation, size of firm, and performance take the reader beyond stylized assumptions about average behaviour in Japan.
