The OECD has invited Nobel laureates and many of the world’s leading thinkers from government, the private sector and academia to debate innovative approaches to the major questions facing humanity. This series summarises their analyses and proposals on the interlinked challenges facing our societies, environment and economies: from the climate emergency to inequality, the digital economy, or the financial system. The OECD’s New Approaches to Economic Challenges (NAEC) initiative was launched in 2012 to investigate the roots and lessons of the financial crisis, and renew and strengthen analytical and policy approaches with fresh thinking, engaged research and dialogue.
