| Abstract: | This paper seeks to explain why more than half of the German service sector firms that introduce a product innovations do not advertise their new or markedly improved product. One part of the explanation is that they do not need to advertise because they are closely related to their customers anyway, and another part of the explanation is that product innovation and product innovation advertising are strategic substitutes. |
