Market Efficiency And The Problem Of Retail Flight, Alicia J. Davis
Market Efficiency And The Problem Of Retail Flight, Alicia J. Davis
Articles
In 1950, 91 % of common stock in the U.S. was owned directly by individual inves tors. Today, that percentage stands at only 23%. The mass exodus of retail investors and their investment dollars has negative implications not only for capital formation and investor protection, but also for market efficiency. Individual investors are often assumed to be noise traders who distort stock prices and harm market functioning. Therefore, some argue that their withdrawal from the market should be of little concern; indeed, it should be celebrated. Recent empirical evidence calls this assertion of retail noise trading into doubt, and this …
Competition Policy And The Technologies Of Information, Herbert J. Hovenkamp
Competition Policy And The Technologies Of Information, Herbert J. Hovenkamp
All Faculty Scholarship
When we speak about information and competition policy we are usually thinking about oral or written communications that have an anticompetitive potential, and mainly in the context of collusion of exclusionary threats. These are important topics. Indeed, among the most difficult problems that competition policy has had to confront over the years is understanding communications that can be construed as either threats to exclude or as offers to collude or facilitators of collusion.
My topic here, however, is the relationship between information technologies and competition policy. Technological change can both induce and undermine the use of information to facilitate anticompetitive …
Governing Knowledge Commons -- Introduction & Chapter 1, Brett M. Frischmann, Michael J. Madison, Katherine J. Strandburg
Governing Knowledge Commons -- Introduction & Chapter 1, Brett M. Frischmann, Michael J. Madison, Katherine J. Strandburg
Book Chapters
“Knowledge commons” describes the institutionalized community governance of the sharing and, in some cases, creation, of information, science, knowledge, data, and other types of intellectual and cultural resources. It is the subject of enormous recent interest and enthusiasm with respect to policymaking about innovation, creative production, and intellectual property. Taking that enthusiasm as its starting point, Governing Knowledge Commons argues that policymaking should be based on evidence and a deeper understanding of what makes commons institutions work. It offers a systematic way to study knowledge commons, borrowing and building on Elinor Ostrom’s Nobel Prize-winning research on natural resource commons. It …
Commons At The Intersection Of Peer Production, Citizen Science, And Big Data: Galaxy Zoo, Michael J. Madison
Commons At The Intersection Of Peer Production, Citizen Science, And Big Data: Galaxy Zoo, Michael J. Madison
Book Chapters
The knowledge commons research framework is applied to a case of commons governance grounded in research in modern astronomy. The case, Galaxy Zoo, is a leading example of at least three different contemporary phenomena. In the first place Galaxy Zoo is a global citizen science project, in which volunteer non-scientists have been recruited to participate in large-scale data analysis via the Internet. In the second place Galaxy Zoo is a highly successful example of peer production, sometimes known colloquially as crowdsourcing, by which data are gathered, supplied, and/or analyzed by very large numbers of anonymous and pseudonymous contributors to an …
