Voluntary Standard Setting Organizations (SSOs) use a consensus process to create new compatibility standards. Practitioners have suggested that SSOs are increasingly politicized, and perhaps incapable of producing timely standards. This paper develops a simple model of standard setting committees and tests its predictions using data from the Internet Engineering Task Force, an SSO that produces many of the standards used to run the Internet. The results show that an observed slowdown in standards production between 1993 and 2003 can be linked to distributional conﬂicts created by the rapid commercialization of the Internet.
Consensus standardization—explicit agreement on compatibility standards—is marred by severe delays. We explore tradeoffs between speed and the quality of outcomes in a private-information model of the war of attrition. In this model, the consensus process can be excessively slow—even on an optimistic view of its quality-selection merits. However, we find that adding “vendor neutral” players can mitigate the tradeoff between screening and delay. We also show that intellectual property policies designed to reduce vested interest, and hence delays, do not necessarily weaken the players' incentive to innovate.
This paper measures the technological significance of voluntary standard setting organizations (SSOs) by examining citations to patents disclosed in the standard setting process. We find that SSO patents are cited far more frequently than a set of control patents, and that SSO patents receive citations for a much longer period of time. Furthermore, we find a significant correlation between citation and the disclosure of a patent to an SSO, which may imply a marginal impact of disclosure. These results provide the first empirical look at patents disclosed to SSOs, and show that these organizations not only select important technologies, but may also play a role in establishing their significance.
This paper studies the intellectual property strategy of firms that participate in the formal standards process. Specifically, we examine litigation rates in a sample of patents disclosed to thirteen voluntary Standard Setting Organizations (SSOs). We find that SSO patents have a relatively high litigation rate, and that SSO patents assigned to small firms are litigated more often than those of large publicly-traded firms. We also estimate a series of difference-in-differences models and find that small-firm litigation rates increase following a patent's disclosure to an SSO while those of large firms remain unchanged or decline. We interpret this result as evidence of a "platform paradox" -- while small entrepreneurial firms rely on open standards to lower the fixed cost of innovation, these firms are also more likely to pursue an aggressive IP strategy that may undermine the openness of a new standard.
This short book chapter documents a large and rather sudden increase in intellectual property disclosure at nine standard setting organizations during the early 1990s. It also examines the specificity of disclosure statements, the significance of disclosed patents, and the differences between disclosing firms. After considering several possible explanations for the increase in disclosure, the paper concludes with a discussion its policy implications.
This is a book chapter that explores the tension between collaboration and competition in the non-market standard setting process—with particular emphasis on the role of intellectual property rights. The chapter develops a simple framework that emphasizes the distinction between standards, implementations, and products. The framework is used to explore a number of factors that influence the efficiency of the standards developing process. I also develop a simple taxonomy of “IPR strategies” for standard setting and close with a discussion of the ongoing policy debates about the hold-up problems created by IPR in standards.
Are CEOs’ attitudes and beliefs linked to their firms’ innovative performance? This paper uses Malmendier and Tate’s measure of overconfidence, based on CEO stock-option exercise, to study the relationship between a CEO’s "revealed beliefs" about future performance and standard measures of corporate innovation. We begin by developing a career concern model where CEOs innovate to provide evidence of their ability. The model predicts that overconfident CEOs, who underestimate the probability of failure, are more likely to pursue innovation, and that this effect is larger in more competitive industries. We test these predictions on a panel of large publicly traded firms for the years 1980 to 1994. We find a robust positive association between overconfidence and citation-weighted patent counts in both cross sectional and fixed-effect models. This effect is larger in more competitive industries. Our results suggest that overconfident CEOs are more likely to take their firms in a new technological direction.
How much are we influenced by an author’s identity when evaluating their work? This paper addresses this question in the context of open standards development. We exploit a natural experiment, whereby author names were occasionally replaced by "et al" in a series of email messages used to announce new submissions to the Internet Engineering Task Force (IETF). By comparing the effect of obscuring high versus low status author names, we measure the impact of status signals on the IETF publication process. Our results suggest that name-based signals can explain up to three-quarters of the difference in publication outcomes across status cohorts. However, this signaling effect disappears for a set of pre-screened proposals that receive more scrutiny than a typical submission. We also show that working papers from high status authors receive more attention on electronic discussion boards, which may help in developing these ideas and bringing them forward to publication.
This paper studies how firms reorganize following diversification, and proposes that firms use outsourcing, or vertical dis-integration, to manage diseconomies of scope. We also consider the origins of scope diseconomies, showing how different underlying mechanisms generate contrasting predictions about the link between within-firm task heterogeneity and the incentive to outsource following diversification. We test these propositions using micro-data on taxicab and limousine fleets from the Economic Census. The results show that taxicab fleets outsource, by shifting towards owner-operator drivers, when they diversify into the limousine business. The magnitude of this shift toward driver ownership is larger in less urban markets where the task performed by taxicab and limousine drivers are more similar. These findings suggest that: (1) firms use outsourcing to manage diseconomies of scope; and (2) inter-agent conflicts are an important source of scope diseconomies.
A growing body of research uses patent citations to analyze economic phenomena, and many of these papers are interested in the distribution of citations over the life of a patent. However, this question leads directly to the age-year-cohort identification problem, i.e. co-linearity between the birth year, citation year, and "age" of a patent. Existing research has relied on functional form assumptions to separate these three effects. This paper proposes an alternative non-parametric identification strategy which uses the lag between application and grant as a source of exogenous variation. We provide statistical evidence to support our assumption that the "citation clock" should not start ticking until a patent actually issues, and we examine the potential bias introduced by our method if the lag between application and grant is correlated with citation levels. Finally, we use our proposed identification strategy to re-examine some prior results on the citation age profile of patents from different technological fields and application-year cohorts.
We develop a simple model that links the adoption of a productivity-enhancing technology to increased vertical integration and a less skilled workforce. We test the model’s key prediction using novel micro data on vehicle ownership patterns from the Economic Census during a period when computerized dispatching systems were first adopted by taxicab firms. Controlling for time-invariant firm-specific effects, firms increase the proportion of taxicabs under fleet-ownership by 12 percent when they adopt new computerized dispatching systems. These findings suggest that increasing a firm’s productivity can lead to increased vertical integration, even in the absence of asset specificity.
