International Migration as a Climate Change Adaptation Strategy

A person with the ability to migrate to higher ground suffers less from climate change.   Nations with larger land areas offer migrants more places they can move to.  Some young economist should take the Alesina and Spolaore model of the number of nations  and incorporate climate change adaptation.  A key comparative static of such a paper would be that merging nations together into larger nations reduces the cost of adapting to climate change because migrants would move to more productive areas within the same nation. Political boundaries hinder efficient migration.   These migrants would vacate areas that are suffering.  For more about my thoughts on international migration and climate adaptation, read this.
