The CEPII Country Profiles put forward an original tool to analyse the insertion of eighty countries in international trade using databases developed by the CEPII. Thus, CHELEM which provides a complete and coherent representation of international trade flows, balance of payments and world revenues since the 1960s; EconMap which allows to project by 2050 or 2100 GDP with its components in a global context and taking into account climate scenarios; EQCHANGE which includes nominal, real and equilibrium effective exchange rates since the 1970s; MAcMap-HS6 which estimates the average country’s protection; BACI which offers harmonised statistics on values and quantities at a very detailed level of products since the late 1980s; and WTFC which defines type and price range of trade flows since 2000, are used to present a consistent set of indicators. Tables and figures are grouped under seven thematic sections: broad patterns; projections; balance & forex; tariff protection; comparative advantages; types & ranges; products & partners. This document specifies the indicators, databases and classifications used in the CEPII Country Profiles.
