In this paper we compare the magnitude of local productivity advantages associated to two different spatial … findings. We detect local productivity advantages for both UA and ID. However, firms located in UA attain a larger Total Factor … Productivity (TFP) premium than those operating within ID. Besides, it turns out that the advantages of ID have declined over time …

We compute aggregate productivity of three categories of regions, classified by level of urbanization in the … Netherlands, from firm-specific total factor productivity (TFP) measures. TFP measures are estimated by a semi … over the period 1997-2006. We analyse the productivity differentials across urbanization categories by decomposing them …

Additionally, the QR and IVQR estimators find a progressively … decreasing, but still positive, effect of employment density along the conditional distribution of labor productivity. …
