This paper examines the role of regional aggregation in measuring agglomeration externalities. Using Dutch … agglomeration externalities at a higher spatial scale. We quantify subgroup differentials and find that high-educated workers have … agglomeration externalities twice as high as low-educated workers. We show that workers who lose their job in denser LLMs experience …

We propose an integrated framework to discuss the empirical literature on the local determinants of agglomeration … density on productivity but we also consider many other local determinants supported by theory. Empirical issues are then … developing economies. We finally provide a discussion of attempts to identify and quantify specific agglomeration mechanisms …
