Appropriability, Preemption, and Firm Performance
نویسندگان
چکیده
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 economic performance, as measured by the stock market valuation of a firm’s R&D assets. Among commonly used ‘nonconventional’ patent strategies, preemptive patenting allows incumbents to strengthen their market power. Consistent with theory, such effect is higher for incumbents with higher ex ante market power and facing a higher threat of entry, and lower when R&D competition is characterized by the discovery of drastic innovations.

Evaluating Appropriability Defenses for the Exclusionary Conduct of Dominant Firms in Innovative Industries
In response to antitrust cases challenging the exclusionary conduct of dominant firms, some dominant firms offer an “appropriability defense”: a claim that prohibiting the challenged conduct would harm innovation by lessening the dominant firm’s return to investment in research and development (R&D) and, in consequence, undermining that firm’s incentive to innovate. This paper explains that an ...
متن کاملEffects of Managerial Ties and Appropriability Regimes on Open Innovation
In today’s globalized world, firms are increasingly seen shifting from the traditional innovation model 1 which relied on a firm’s internal R&D to the more porous open innovation paradigm which utilizes resources both internal and external to a firm to come up with innovations. However success in the open innovation paradigm is contingent upon some internal and external factors of a firm. This ...
متن کاملIntra-Organizational Integration and Innovation: Organizational Structure, Environmental Contingency and R&D Performance
It is widely thought that intra-firm integration has a positive effect on organizational performance, especially in environments characterized by complex and uncertain information. However, counter arguments suggest that integration may limit flexibility and thereby reduce performance in the face of uncertainty. Research and development activities of a firm are especially likely to face complex...
متن کاملAppropriability and the timing of innovation: Evidence from MIT inventions
At least since Arrow (1962), economists have believed that strong property rights are necessary for firms to invest in innovation. This belief was a key principle underlying the Bayh-Dole Act, which gave universities the right to own and license federally funded inventions, because the commercialization of university inventions requires private firm investment in development, given the early st...
متن کاملOptimal Timing of Firm's R&D Investment under Incomplete Information: A Real Options and Game-theoretic Approach
In a real options and game-theoretic framework, this paper examines the optimal R&D investment timing of an incumbent (firm 1) under uncertainty, which faces the threat of preemption by a potential entrant (firm 2). We incorporate incomplete information into the model by assuming that the incumbent does not know the entrant’s investment threshold but know its distribution. We find that incomple...
