CEPII, Recherche et Expertise sur l'economie mondiale

Update : adding of years 2007-2015

Mise à jour: February 10, 2017

CEPII makes available a "square" gravity dataset for all world pairs of countries, for the period 1948 to 2015, allowing the estimation of international flows as a function of GDP, population and trade costs.

We also provide for replication of Head et al. (2010) , a lighter dataset covering trade flows (cleaned and treated as described in the data appendix) but restricted to observations where those trade flows are non-missing.
 Methodology: a Short Description
The main variables relating to trade costs come from GeoDist, the CEPII distance dataset. A few variables are added to GeoDist. Furthermore, Gravity is arranged in such a way that it can be easily merged with any matrix of bilateral flows (trade,  FDI, migrations, or other types of bilateral flows),  using standard ISO codes for countries and for any year between 1948 and 2015.

GDP and populations come mainly from the World Bank Development Indicators (WDI). regional trade agreements and currency unions are built from Baier and Bergstrand, the WTO web site, Frankel (1997) and Glick and Rose (2002).
