What will the global economy look like in a generation? EconMap is the database developed by the CEPII in 2010 to picture the world economy in the long term. Based on a three-factor production function of labour, capital and energy, plus two forms of technological change, we propose a long-run growth scenario for 170 countries at the 2050 horizon, relying on the model MaGE (Macroeconometrics of the Global Economy).
