A rich literature links knowledge inputs with innovative outputs. However, most of what is known is restricted to manufacturing. This paper analyzes whether the three aspects involving innovative activity - R&D; innovative output; and productivity - hold for knowledge intensive services....

Hochentwickelte Volkswirtschaften wie Deutschland können im internationalen Wettbewerb am ehesten mit solchen Dienstleistungen und Gütern Erfolge erzielen und damit Wachstum und Beschäftigung sichern, die einen hohen Einsatz von Wissen und Technologie erfordern. Die Studie untersucht deshalb...

In Germany, the productivity of professional services, a sector dominated by micro and small firms, declined by 40 percent between 1995 and 2014. This productivity decline also holds true for professional services in other European countries. Using a German firm-level dataset of 700,000...

We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over...

This paper analyzes the effect of agglomeration economies on firms' total factor productivity. We propose the use of a control function approach to overcome the econometric issue inherent to the two-stage approach commonly used in the literature. Estimations are conducted separately for four...
