This indicator is a measure of the dispersion of trade value across an exporter’s partners. A county with a preponderance of trade value concentrated in a very few markets will have an index value close to 1. Thus, it is an indicator of the exporter’s dependency on its trading partners and the danger it could face should its partners increase trade barriers. Measured over time, a fall in the index may be an indication of diversification in the exporter’s trading partnerships. The user has the option of selecting product clusters, which will return the index calculated only for that specified subset of countries. Note that if a country exports to only a single market, then the indicator returns no value.
