We examine how firms’ productivity level, measured by the total factor productivity (TFP), is affected by their use of academic workers. A panel dataset of Norwegian manufacturing firms is used. Firms’ production level is shown to be negatively affected by their share of academic workers, but we find no clear relationship between this share and the TFP. If we account for the fact that there is an interaction between the share of academic workers and the capital stock, we find that this share has a non‐significant effect on the production level.
