Abstract

What factors underlie industry differences in research intensity and productivity growth? Wedevelop a multi-sector endogenous growth model allowing for industry specific parameters inthe production functions for output and knowledge, and in consumer preferences. We findthat industry differences in both productivity growth and R&D intensity mainly reflectdifferences in "technological opportunities", interpreted as parameters of knowledgeproduction. These include the capital intensity of R&D, knowledge spillovers, anddiminishing returns to R&D. Among these parameters, we find that the degree of diminishingreturns to R&D is the dominant factor when the model is calibrated to account for crossindustrydifferences in the US.
