Database Specific
Database Specific Abstract AbstractThe database on Institutional Characteristics of Trade Unions, Wage Setting, State Intervention and Social Pacts (ICTWSS) has been developed by Prof. Jelle Visser at the University of Amsterdam. It was first released in May 2007. In its initial form, the ICTWSS database combined data from various sources and projects with a main focus on trade union in EU and OECD countries, collective bargaining and employment relations in Europe, and social pacts. In 2021, the ICTWSS database has been rebranded as the OECD/AIAS ICTWSS database. This new name reflects the joint effort by the OECD and AIAS-HSI to ensure the continuation of the database after Prof. Visser’s retirement. The OECD/AIAS ICTWSS database is publicly available at:
