Growth patterns through the 1990s and into this decade have turned received wisdom on its head. For most of the post-war period, OECD countries with relatively low GDP per capita grew faster than richer countries. Since the late 1990s, however, that pattern has broken down with the United States notably drawing further ahead of the field. This publication provides a comprehensive overview of growth drivers across the OECD and the extent to which disparities are attributable to factors like new technology and R&D, macroeconomic policy, education and training, labour market flexibility, product market competition, and barriers to business start-up and closure.
