We study the effect of new product introduction on firm value. Using a unique sample on mobile phone handset introduction by 16 major handset manufacturers over 10 years, we distinguish between imitative product introduction and truly innovative product introduction.

We use the data compiled from the USPTO patent and patent citations concerning the patented knowledge intensive technologies in three areas : cryptography, image analysis and data processing/software. The data is restricted to those patents between the years 1980-2003 that have two or more assignees, i.e. we consider only joint patents. We find some evidence

Our study aims at shedding light on the organizational mechanisms that produce differences in the firmsŽ innovation performance.

However, we find evidence that the public R&D finance has substantially influenced the innovation output of the firms that have

The primary findings of our study suggest that software firms that adopt the OSS-based business model are notably less productive than companies that merely offer proprietary software solutions. Our estimation results further show that the OSS business model adopters have not become notably less productive after beginning to supply OSS. Therefore, its seems that not
