CEPII presents growth scenarios for 128 countries to 2050, based on a three-factor production function that includes capital, labour and energy. CEPII improves on the literature by accounting for the energy constraint through dynamic modelling of energy productivity, and departing from the assumptions of either a closed economy or full capital mobility by applying a Feldstein-Horioka-type relationship between savings and investment rates.
Results suggest that, accounting for relative price variations, China could account for 28% of the world economy in 2050, which would be much more than the United States (14%), India (12%), the European Union (11%) and Japan (3%). They suggest also that China would overtake the United States around 2025 (2035 at constant relative prices). However, in terms of standards of living, measured through GDP per capita in purchasing power parity, only China would be close to achieving convergence to the US level, and only at the end of the simulation period.
ORBIS is powered by ESPAS, the European Strategy and Policy Analysis System, a unique inter-institutional project aimed at strengthening the EU's efforts in the crucial area of forward planning. ESPAS brings together the European Commission, the European Parliament, the Secretariat General of the Council of the European Union and the European External Action Service to strengthen the Union's collective administrative capacity to identify and analyse the key trends and challenges, and the resulting policy choices, which are likely to confront Europe and the wider world in the decades ahead.
