Task Polarisation in Japanese Labour Market: Evidence form the Japanese employer-employee matched data

This is an international project involving researchers from Japan, Australia, the US, Canada and Denmark.

Nobu Yamashita is part of a team developing a practical measure of skill of workers that focuses on the content of the tasks in which workers engage, and whether they perform tasks that require specialised expertise or ability.

The skill content of jobs (tasks) is matched to the Career Matrix which is a comprehensive database of the skill content of occupations developed by the Japan Institute of Labour Policy and Training.

This is then merged to the employer-employee matched dataset by combing firm-level data of the Basic Survey of Business Activities by the Ministry of Economy, Trade and Industry (METI) and worker-level information (age, sex, education, the tenure, salaries and wages) extracted from the Basic Survey on Wage Structure (BSWS), compiled by the Ministry of Health, Labour and Welfare. In 2015, Nobu spent three months working on these datasets at Hitotsubashi University.

This is an international project involving researchers from University of Tokyo (Japan), University of Queensland (Australia), the John Hopkins University (US), McMaster University (Canada) and Arhus University (Denmark).
