We study the impact of agglomeration effects on firms’ total factor productivity (TFP) for industry groups defined by technology intensity. This allows for non-uniform effects on firms depending on their technological level. We find that urban economies have the largest impact on firm productivity in high-technology industries, while they have no effectin low-technology industries. For firms in the ...
