CEPR mourns the passing of the extraordinary French activist and intellectual Bernard Cassen, who played a key role in building the global movement of opposition to neoliberalism, first by helping create, in 1998, the Association for the Taxation of Financial Transactions and for Citizens’ Action (ATTAC) — which spread to over 40 countries — and then as the driving force behind the 2001 creation of the World Social Forum, a worldwide gathering of social movements opposed to corporate globalization. Cassen, who directed the influential foreign policy monthly Le Monde Diplomatique between 1996 and 2008, was also a tireless advocate for Latin America’s political and economic independence and a fierce and effective critic of Europe’s neoliberal turn in the 1990s and 2000s. With his big ideas and big dreams he taught us that “another world is possible.” R.I.P.
