On November 18-21, 2009, researchers from the MPIfG met with leading European and American researchers at a conference on "Commonalities of Capitalism." They debated capitalism's principles and its crises, as well as where ethics and passion play a role. They also discussed various perceptions of capitalism, which can have either a historical-institutionalist orientation or a basis in philosophical pragmatism. The issue of a "New Deal" for the twenty-first century figured prominently as well. Results of the conference will be published in a special issue of Socio-Economic Review.
