A new study by Neil Lee and Andrés Rodríguez-Pose of the London School of Economics takes a hard look at this important issue. In a forthcoming paper in the journal, Environment and Planning A (that expands upon a working paper from the U.K.-based innovation think tank Nesta, summarized in a post over at the World Economic Forum blog), they takes a close empirical look at the varied contributions to innovation made on the one hand by creative firms, and on the other by individual creative workers, regardless of where they work.
