Title
Productivity distribution, firm heterogeneity, and agglomeration: Evidence from firm-level data
Abstract
This paper empirically examines how productivity distributions of firms vary across regions based on Japan's manufacturing census data. We find that firm productivity is distributed with wide dispersions, especially in core regions. Our firm-level estimates demonstrate that the productivity distribution of firms tends to be noticeably left-skewed, deviating from the normal distribution, especially in regions with weak market potential but also in agglomerated or urbanized regions. These findings suggest that agglomeration economies are likely to accommodate heterogeneous firms that co-exist in the same region.
