When do firms get ideas from hiring PhDs?

Research Policy, 2020, vol. 49, issue 3

Abstract: Hiring new PhDs allows firms to access recent scientific advances. We develop new measures based on correlated topic models to estimate the similarity of patents and dissertations, and apply these measures to PhD-invented firm patents in the German laser industry. Patents are more exploratory for the firm if the underlying dissertation work is less similar to the firm’s prior knowledge stock. Patents filed prior to dissertation submission are more exploratory. PhD-invented patents did not become less exploratory when Germany adopted university ownership in academic inventions.
