Abstract in English:

In this paper we quantify the "Cost of Non-Europe", i.e. the trade-related welfare gains each country member has reaped from the European Union. Thirty years after the terminology of Non-Europe was used to give estimates of the gains from further integration, we use modern versions of the gravity model to estimate the trade creation implied by the EU, and apply those to counterfactual exercises where for instance the EU returns to a "normal'', shallow-type regional agreement, or reverts to WTO rules. Those scenarios are envisioned with or without the exit of the United Kingdom from the EU (Brexit) happening, which points to interesting cross-country differences and potential cascade effects in doing and undoing of trade agreements.

Abstract in English:

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.

Abstract in English:

Are presented growth scenarios for 147 countries to 2050, based on MaGE (Macroeconometrics of the Global Economy), a three-factor production function that includes capital, labour and energy. We improve 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 33% of the world economy in 2050, which would be much more than the United States (9%), India (8%), the European Union (12%) and Japan (5%). They suggest also that China would overtake the United States around 2020 (2040 at constant relative prices). However, in terms of standards of living, measured through GDP per capita in purchasing power parity, China would still lag 10 percent behind the United States at the 2050 horizon.

MIRAGE-e: A General Equilibrium Long-term Path of the World Economy

Abstract in English:

Thinking of how the relative sizes of countries and how the geography of world production and trade will be affected in the long run must be based on sound economic reasoning about the determinants of long term growth. It must also be embedded in a general equilibrium framework that takes account of the interactions among markets and sectors, as well as between countries. This paper takes stock of a three phase research project. The first step consists of deriving and estimating a three-factor (labour, capital, energy) macroeconomic growth model for a large set of individual countries, which fits two forms of technological progress (standard TFP and energy efficiency). The second step consists of recovering the sectoral detail with an energy-oriented Computable General Equilibrium model of the world economy calibrated to fit these projections. In a third step we confront the assumptions for our baseline to alternative scenarios.
