TRANSWORLD was a consortium of 13 academic and research centres from the EU, the US and Turkey formed to research the evolution of the transatlantic relationship and its role in shaping global governance architectures. Funded under the 7th framework of the European Commission, TRANSWORLD, launched in March 2012 as a three-year project.

The project examined the future of the transatlantic relationship in four main areas (economics, security, climate change, and human rights and democracy), by combining an inter-disciplinary analysis of transatlantic relations. In so doing, TRANSWORLD contributed to an inter-disciplinary transatlantic research area, with in-built connections to policymaking.

Chatham House led the Work Package on transatlantic economic relations, together with the Istituto Affari Internazionali (Rome), the German Marshall Fund of the United States (Washington), the University of Edinburgh (Edinburgh), and the Sabanci University (Istanbul).

The research focused on long-term trends in the world economy and policy adjustments made by the US and the EU. The aim was to assess whether in the field of international economics the transatlantic relationship is a) drifting apart b) a functional partnership or c) an enduring partnership.
