The impact of environmental degradation on migration flows across countries

In the latest working paper the authors try to answer the question whether environmental degradation may contribute to forced migration. A gravity regression model is used to detect the impact of global environmental factors on the migration flows across countries of the world. To the knowledge of the authors, this working paper is the first to include environmental variables in a gravity model, and it is shown that environment has a positive significant impact on migration, which until now has been considered unrelated.
