Export Similarity (updated 1962-2020)

Our 2017 Journal of Conflict Resolution (JCR) paper (\"Export Similarity and International Conflict\") uses a measure of export similarity between countries for the years 1962-2000. In February 2023, we updated this measure to cover 1962-2020. Note that this version is based on the Atlas of Economic Complexity whereas the original version was based on the World Trade Flows data. The two measures are highly correlated (0.92). For more information, please read the \"Update Notes\" document below. You can find the original measure in the 2017 JCR replication file.
