Notes: Chapter 2

1. The full statement was: "[A]ny information obtained, say a new method of production, should, from the welfare point of view, be available free of charge (apart from the costs of transmitting information). This insures optimal utilization of the information but of course provides no incentive for investment in research. In a free enterprise economy, inventive activity is supported by using the invention to create property rights; precisely to the extent that it is successful, there is an underutilization of information." Kenneth Arrow, "Economic Welfare and the Allocation of Resources for Invention," in Rate and Direction of Inventive Activity: Economic and Social Factors, ed. Richard R. Nelson (Princeton, NJ: Princeton University Press, 1962), 616-617.

6. At most, a "hot news" exception on the model of International News Service v. Associated Press, 248 U.S. 215 (1918), might be required. Even that, however, would only be applicable to online editions that are for pay. In paper, habits of reading, accreditation of the original paper, and first-to-market advantages of even a few hours would be enough. Online, where the first-to-market advantage could shrink to seconds, "hot news" protection may be worthwhile. However, almost all papers are available for free and rely solely on advertising. The benefits of reading a copied version are, at that point, practically insignificant to the reader.

Walsh, "Protecting Their Intellectual Assets: Appropriability Conditions and Why U.S. Manufacturing Firms Patent (or Not)" (working paper no. 7552, National Bureau Economic Research, Cambridge, MA, 2000); Richard Levin et al., "Appropriating the Returns from Industrial Research and Development"Brookings Papers on Economic Activity 3 (1987): 783; Mansfield et al., "Imitation Costs and Patents: An Empirical Study," The Economic Journal 91 (1981): 907.

8. In the 2002 Economic Census, compare NAICS categories 5415 (computer systems and related services) to NAICS 5112 (software publishing). Between the 1997 Economic Census and the 2002 census, this ratio remained stable, at about 36 percent in 1997 and 37 percent in 2002. See 2002 Economic Census, "Industry Series, Information, Software Publishers, and Computer Systems, Design and Related Services" (Washington, DC: U.S. Census Bureau, 2004).

9. Levin et al., "Appropriating the Returns," 794-796 (secrecy, lead time, and learningcurve advantages regarded as more effective than patents by most firms). See also F. M. Scherer, "Learning by Doing and International Trade in Semiconductors" (faculty research working paper series R94-13, John F. Kennedy School of Government, Harvard University, Cambridge, MA, 1994), an empirical study of semiconductor industry suggesting that for industries with steep learning curves, investment in information production is driven by advantages of being first down the learning curve rather than the expectation of legal rights of exclusion. The absorption effect is described in Wesley M. Cohen and Daniel A. Leventhal, "Innovation and Learning: The Two Faces of R&D," The Economic Journal 99 (1989): 569-596. The collaboration effect was initially described in Richard R. Nelson, "The Simple Economics of Basic Scientific Research," Journal of Political Economy 67 (June 1959): 297-306. The most extensive work over the past fifteen years, and the source of the term of learning networks, has been from Woody Powell on knowledge and learning networks. Identifying the role of markets made concentrated by the limited ability to use information, rather than through exclusive rights, was made in F. M. Scherer, "Nordhaus's Theory of Optimal Patent Life: A Geometric Reinterpretation," American Economic Review 62 (1972): 422-427.
