It has been argued that platform technology owners co-create business value with other firms in their platform ecosystems by encouraging complementary invention and exploiting indirect network effects. In this study we examine whether participation in an ecosystem partnership improves the...

In this study we examine the antecedents of small independent software vendor (ISV) decisions to join a platform ecosystem. Using data on the history of partnering activities from 1201 ISVs from 1996 to 2004, we find that appropriability strategies based on intellectual property rights and the...

We examine whether ownership of intellectual property rights (IPR) or downstream capabilities is effective in encouraging entry into markets complementary to a proprietary platform by preventing the platform owner from expropriating rents from start-ups. We study this question in the context of...

The impact of strategies used to appropriate innovation rents on firm performance is analyzed using a sample of U.S. public manufacturing firms. Stronger appropriability at the firm level, achieved through patent protection or the ownership of specialized complementary assets, leads to superior...

This paper analyzes the relationship between technology licensing and the effectiveness of patent protection. Using the 1994 Carnegie Mellon survey on industrial R&D in the United States, we develop and test a simple structural model in which the patenting and licensing decisions are jointly...

We analyze the effect of patenting on R&D with a model linking a firm's R&D effort with its decision to patent, recognizing that R&D and patenting affect one another and are both driven by many of the same factors. Using survey data for the U.S. manufacturing sector, we estimate the increment to...
