The Dynamic Gravity dataset seeks to make several improvements over the commonly used dataset made available by CEPII. Specifically, we have aimed to closely follow the ways in which countries and borders have changed between 1948 and 2016, provide more information about countries and their relationships, and have greater transparency with respect to sources and methods underlying the construction of the variables. For more details, please see the  paper, which provides a more in-depth discussion of the differences and similarities between the two datasets.
