聘请新的博士可以让公司获得最新的科学进步。我们开发了新的措施的基础上相关的主题模型来估计专利和论文的相似性，并将这些措施应用于博士发明的公司专利在德国激光行业。专利是更具探索性的公司，如果基本的论文工作是不太相似的公司的先验知识股票。在论文提交之前提交的专利更具探索性。当德国在学术发明中采用大学所有制时，博士发明的专利并没有变得不那么具有探索性。
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.
