The database on Institutional Characteristics of Trade Unions, Wage Setting, State Intervention and Social Pacts (ICTWSS) was 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 was rebranded as the OECD/AIAS ICTWSS database to reflect the joint effort by the OECD and AIAS-HSI to ensure the continuation of the database following Prof. Visser’s retirement. The OECD/AIAS ICTWSS database is publicly available at: http://www.oecd.org/employment/ictwss-database.htm
