Are product and Process Innovations Independent of Each Other

This paper studies the relationship between product- and process-innovation. After discussing the determinants of product- and process-innovation, a simultaneous equation model is estimated. A positive impact of product-innovation on process-innovation can be proved, but no evidence for a reverse effect to the respect to the inclusion of product-innovation.
