This paper studies how firm heterogeneity in terms of productivity affects the balance between agglomeration and … mark-ups. It shows that firm heterogeneity matters. However, whether it shifts the balance from agglomeration to dispersion … 'evenness'. Accordingly, the role of firm heterogeneity in selection models of agglomeration cannot be fully understood without …
