The EMU Choices consortium gathered data on the positions of member states on different issues of fiscal and economic integration that have been discussed since Maastricht. The resulting datasets are based on primary and secondary documents as well as about 180 interviews conducted in all 28 EU member states and EU institutions in Brussels. The final datasets will be made available as the flagship publications get accepted in academic journals in the course of 2018 and 2019.

There are 3 principal datasets:

  1. EMU Positions: This dataset of member state preferences on contested issues of fiscal and economic integration that were discussed between 2010 and 2015. It covers 47 issues related to EFSF, ESM, Six/Two Packs, Fiscal Compact and the banking union legislation and is based on the document analysis complemented by 25 validation interviews.
  2. EMU Formation: This dataset is focused on the role of national and international actors in the formation of member states’ preferences on four contested issues as well as the roles and strategies of  national parliaments and governments in EU negotiations. It is based on 141 interviews in all 28 member states.

The legal experts compiled fact sheets on legal foundations for fiscal, economic, and monetary integration for all 28 EU member states. They provide concise information on the main characteristics of the national constitutional systems, including the system and role of national jurisprudence, parliaments and governments. Further, they brief on the constitutional foundations and limits in the field of Economic and Monetary Union. This covers among others specific constitutional provisions on EMU membership, accession, treaty amendments, or limits to the (further) transfer of powers through Treaty amendments.
