The OSE was contracted by the European Trade Union Institute (ETUI) to conduct research, which resulted in a book on “Social developments in the European Union 2013”. The 15th edition of this publication (published in July 2014) featured authors such as Anton Hemerijck (Fault lines and silver linings in Europe’s social market economy), Frank Vandenbroucke, Bart Vanhercke and John Morley (A European Social Union), and Ferdinand Fichtner (Euro area-wide unemployment insurance).
