We examine the externality effects of R&D investments. We find that firms’ future operating performance is positively related to industry peers’ (all peer firms, or R&D leaders in the industry) R&D expenditures. Firms also tend to experience positive abnormal returns following industry peers’ high R&D expenditures. This suggests that the market not only under react to a firm’s own R&D investmen...

In two-sided markets an intermediary brings together two distinct customer populations, such as buyers and sellers on an e-commerce platform. In these markets the growth process of customer populations depends on network effects both within and between buyers and sellers. Thus, assigning IT investments to customer populations and quantifying the monetary value of these investments is complex. W...
