National Parliaments in the EU Dataset (NPdata)

The National Parliaments in the European Union Dataset (NPdata) codes formal rights and mechanisms for parliamentary involvement in EU affairs from 1952 to 2020. It contains information on oversight institutions, which specify parliamentary information and participation rights in relation to the government’s involvement in EU policymaking. NPdata also includes information on parliamentary rights in the European Semester (ES) and decision-making of the European Stability Mechanism (ESM).

The data is available via Harvard Dataverse.
