One of the defining features of the global economic landscape over the past decade has been the increasing integration and cohesion of the transatlantic economy. Globalization is happening faster and reaching deeper between Europe and America than between any other two continents. Transatlantic markets are the cutting edge of globalization. Key sectors of the transatlantic economy are integrating as never before. Europeans and Americans have become so intertwined that they are literally in each other¡¯s business. These linkages underpin a $3 trillion economy that provides up to 14 million ¡®insourced jobs¡¯ on both sides of the Atlantic. Deep integration, however, can also generate frictions when different systems rub up against each other. Neither the framework for our relationship nor the ways our governments are currently organized adequately capture these new realities. Case studies illustrate the phenomenon of deep transatlantic integration and its implications for a truly free Transatlantic Market in such sectors as aerospace and civil aviation, biopharmaceuticals, services, financial markets and telecommunications, and in such controversial policy areas as climate change and emissions trading, corporate governance and chemicals regulation.
