Jobs versus amenities in the analysis of metropolitan migration
Abstract:
"This paper demonstrates that jobs and wages are considerably more important than location-specific amenities in explaining net metropolitan migration of employed persons [in the United States]. These results, which are derived mainly from a unique set of annual migration data, differ considerably from the earlier findings of P. E. Graves...that show amenities to be powerful contributors to the analysis of net metropolitan migration. Several hypotheses are offered and tested to explain the appreciable difference between Grave's results and those of the present study, but the importance of economic factors as opposed to amenities persists."
