University versus Firm Knowledge Spillovers- a Comparison of Productivity E¤ects in Swedish Regions¤

This paper uses a new Swedish dataset of 299 …rms, aimed at analysing within-regional spillover e¤ects of …rms ’ and univeristies ’ research on the productivity of …rms for 1997. The regional unit of analysis is the labour-market region, a functional region de…ned based on commuting patterns. We believe this is a more appropriate region for analysis than those pre-viously used. Due to statistical problems, which may be the result of spatial autocorrelation, we …nd no evidence whatsoever of spillover e¤ects of knowledge, but the results must be considered as preliminary.
