  • (written as Agglomeration)
    The process by which economic activity becomes increasingly concentrated in a geographical area, like a city. Agglomeration tends to increase when there are beneficial externalities for businesses arising from adjacency to other businesses (as in shopping malls) or where skills can be shared, and to decrease when the externalities become negative (as through congestion or pollution, or criminal activity that itself is nurtured by beneficial - to criminals - externalities also arising from agglomeration).
