Based on a sample of German inovating firms that contains information on formal and informal innovation cooperation between customers and suppliers, we state that firms perceive informal cooperation as being more important than formal cooperation modes. We then investigate the determinants of firms’ decisions to engage into the respective espective cooperation modes. In line with previous empirical work, we do not find much empirical evidence for the relevance of incoming spillovers. In addition, our results suggest that this finding holds as well for informal cooperations. A firm’s ability to protect its proprietary innovations, however seems to be a key determinant of formal as well as informal cooperations. Furthermor absorptive capacity and the organizational structur of in-house R&D play an important role. Another relevant driver of vertical cooperations are the innovation dynamics at the industry level. Firms who operate an R&D department and firms who ar are involved in costly R&D projects ojects lend to cooperate formally rather than informally.
