The document discusses the future of productivity and ways to stimulate productivity growth. It notes that productivity growth has slowed across developed economies. While some firms at the global productivity frontier continue to see strong growth, diffusion of productivity gains to other firms is declining. This is widening productivity gaps. The document recommends ways to stimulate diffusion, including through trade integration, reallocating resources more efficiently to more productive firms, and maintaining investment in innovation through public and private research. International cooperation, improving university-industry collaboration, and reviewing innovation policy portfolios are also suggested.
