This report presents a comprehensive overview of both recent and long-term trends in productivity levels and growth across OECD countries and, where possible, in accession countries. It covers a range of topics, including recent developments in labour productivity, economic growth, sectoral reallocation, and multifactor productivity - both at the industry level and adjusted for cyclical effects. The report also examines trends in investment, labour productivity by firm size, and presents experimental estimates of productivity developments in 2024 for all 38 OECD member countries.
