Is the EU a superpower?

As China and the US battle for global supremacy, the EU seems to remain in the shadows. But what if the EU had been shaping the world economy all along without anybody noticing? Could its soft power be strong enough to shape regulations all over the world? What impact does such influence have over its own economy? This week, Giuseppe Porcaro and Guntram Wolff are joined live by Ashoka Mody, Professor in International Economic Policy at the Princeton University, and Anu Bradford, author of the book "The Brussels Effect: How the European Union rules the world".
