Given the increasingly high cost of new product development (NPD), it is important for firms to terminate unsuccessful NPD projects as soon as possible. This article investigates the role of intellectual capital in the discontinuation of NPD projects. The three dimensions of intellectual capital (human, structural, and social capital) are posited to decrease the likelihood of discontinuation of NPD projects, while contextual factors such as the firm's discontinuation experience and the size of the drug development portfolio are expected to affect this relationship. The research model is tested using a unique data set of 1,168 drug discovery and development projects. The results suggest that NPD projects rich in all three dimensions of intellectual capital are less likely to be discontinued. The size of the firm's drug development portfolio, however, is found to mitigate these effects, while discontinuation experience enhances the relationship between intellectual capital and discontinuation duration. As only a fraction of new product development initiatives result in success, timely discontinuation of unsuccessful projects is critical for sustained performance of organizations. Our findings make an important contribution to this stream of work. By highlighting the role of intellectual capital in the discontinuation process, we offer an interesting twist to the literature that invariably assumes intellectual capital to be important for innovation.

In this study, we explore the extent to which diversity of educational levels among research scientists and engineers (RSEs) in the context of a firm's level of technological diversity influences innovation performance. We used data from the 2004-2008 National R&D Survey in Singapore. The results from 366 firms across different industries indicate that when a firm's technological domains are heterogeneous, those firms with an RSE workforce comprising similar educational levels have positive innovation performance, measured as the number of patent applications, while those comprising diverse educational levels have negative innovation performance. Our further exploration of the positive interaction between technological domain heterogeneity and similarity of educational levels suggests that firms that had a high ratio of RSEs with lower educational levels had more positive patent outcomes compared to those that had a high ratio of RSEs with higher educational levels. The results show that there are limits to the strength of technological diversity in a firm's absorptive capacity as explained by organizational demography.
