Recent empirical work has pointed to a positive correlation between product market competition and productivity growth. In this lecture we try to reconcile this evidence with the Schumpterian growth paradigm. Three alternative explanations are successively considered, respectively based upon agency considerations, the tacit nature of knowledge, and the decomposition of R and D activities into research and development.
