COUNTERFEITERS: FOES OR FRIENDS? Yi Qian
Counterfeits ... steal demand from low-end authentic products, but [have] positive spillover effects for high-end authentic products.
In fiscal 2009, the U.S. Customs and Border Protection seized more than $260 million worth of counterfeit goods, with counterfeit footwear accounting for 40 percent of the total seizures. Counterfeit footwear has topped the seizure list of the customs service for four years. How does the existence of such counterfeits affect the sales of authentic products?
In Counterfeiters: Foes or Friends? (NBER Working Paper No. 16785), author Yi Qian analyzes product data from Chinese shoe companies over 1993-2004. She can study the impact of policy changes, such as the 1995 change in government enforcement efforts in monitoring footwear trademarks in China. That change had different effects on counterfeit entry for branded companies with varying degrees of closeness to the Chinese government.
Qian finds that counterfeits have positive advertising effects for the brand of shoes they copy. However, they have negative substitution effects for the authentic products, driving buyers away from the authentic shoe to the counterfeit one. For sales of high-end authentic products, the positive advertising effect dominates the substitution effect. For sales of low-end authentic products, the negative substitution effect outweighs the advertising effect. All of the effects last for a few years before leveling off. And, these different effects for different products reinforce incentives for authentic producers to innovate and to move upward in the quality portfolio. Finally, after the entry of counterfeiters, market shares for the higher quality products increase while those of the lower end products decline.
Qian tests these results by conducting some surveys and finds similar effects regarding the purchase intent of high-end, medium-end, and low-end branded products. Her subjects' responses suggest that counterfeits signal brand popularity, at least to some consumers. Counterfeits thus appear to steal demand from low-end authentic products, but their presence has positive spillover effects for high-end authentic products.

Levine on Blog Spam comments(2)] A paper Peter J. Huckfeldt and Christopher R. Knittel examining generic entry. Not a great advertisement for patents:
We study the effects of generic entry on prices and utilization using both event study models that exploit the differential timing of generic entry across drug molecules and cast studies. Our analysis examines drugs treating hypertension, high blood pressure, type 2 diabetes, and depression using price and utilization data from the Medical Expenditure Panel Survey. We find that utilization of drug molecules starts decreasing in the two years prior to generic entry and continues to decrease in the years following generic entry, despite decreases in prices offered by generic versions of a drug. This decrease coincides with the market entry and increased utilization of branded reformulations of a drug going off patent. We show case study evidence that utilization patterns coincide with changes in marketing by branded drug manufacturers. While the reformulations---often extended-release versions of the patent-expiring drug---offer potential health benefits, the FDA does not require evidence that the reformulations are improvements over the previous drug in order to grant a patent. Indeed, in a number of experiments comparing the efficacies of the patent-expiring and reformulated drugs do not find statistical differences in health outcomes calling into question the patent-extension policy.

While it's been watered down a bit, it's still quite obnoxious, and almost bound to choke off innovation. Via Hinnerk Gnutzmann a group of European academics, largely lawyers, has a petition against the current form of the ACTA. It's quite a moderate document - it conceded the basic usefulness of ACTA, which I view as very counterproductive - but still represents a step in the right direction. If I were a European academic I would sign it. [Posted at 05/02/2011 11:41 PM by David K. Levine on Blocking Technology comments(1)] As do Joel and his coauthors. I've long wondered about the role of "mechanics" and other tinkerers - if you ask me why not the industrial revolution in Rome my answer would be: not enough of the low level tinkerers needed to make technology take off. I'm glad to see some careful research into this.
The Rate and Direction of Invention in the British Industrial
Revolution: Incentives and Institutions
by Ralf Meisenzahl, Joel Mokyr
Abstract:
During the Industrial Revolution technological progress and
innovation became the main drivers of economic growth. But why was
Britain the technological leader? We argue that one hitherto little
recognized British advantage was the supply of highly skilled,
mechanically able craftsmen who were able to adapt, implement,
improve, and tweak new technologies and who provided the micro
inventions necessary to make macro inventions highly productive and
remunerative. Using a sample of 759 of these mechanics and
engineers, we study the incentives and institutions that facilitated
the high rate of inventive activity during the Industrial Revolution.
First, apprenticeship was the dominant form of skill formation.
Formal education played only a minor role. Second, many skilled
workmen relied on secrecy and first-mover advantages to reap the
benefits of their innovations. Over 40 percent of the sample here
never took out a patent. Third, skilled workmen in Britain often
published their work and engaged in debates over contemporary
technological and social questions. In short, they were affected by
the Enlightenment culture. Finally, patterns differ for the textile
sector; therefore, any inferences from textiles about the whole
economy are likely to be misleading.

Did Plant Patents Create the American Rose?
by Petra Moser, Paul W. Rhode - #16983 (DAE PR)
Abstract:
The Plant Patent Act of 1930 was the first step towards creating
property rights for biological innovation: it introduced patent
rights for asexually-propagated plants. This paper uses data on
plant patents and registrations of new varieties to examine whether
the Act encouraged innovation. Nearly half of all plant patents
between 1931 and 1970 were for roses. Large commercial nurseries,
which began to build mass hybridization programs in the 1940s,
accounted for most of these patents, suggesting that the new
intellectual property rights may have helped to encourage the
development of a commercial rose breeding industry. Data on
registrations of newly-created roses, however, yield no evidence of
an increase in innovation: less than 20 percent of new roses were
patented, European breeders continued to create most new roses, and
there was no increase in the number of new varieties per year after
1931.

Researchers warn this will destroy prospects for stem cell treatments in Europe, driving potential investors to patent-friendly China, Japan and the US." The article is here.
Wow! Patent friendly China....The rest of the article doesn't give you a lot of confidence in "scientists." [Posted at 04/27/2011 11:52 AM by David K. Levine on IP as a Joke comments(1)] Dear Professors Boldrin and Levine,
We are writing to you regarding your book, Against Intellectual Monopoly.
We have both enjoyed, and been stimulated by, your book, and are in considerable agreement with your overall thesis that intellectual property protection is not conducive to technological innovation, at least not in the way claimed in standard economics. One of us has found it an invaluable help in teaching and research.
However, we would like to bring to your attention some facts about the invention of the radio, which you discuss in chapter 8 of the book. In it you refer to Hong's work and mention the roles of Lodge, Tesla and Popov in undermining Marconi's claim to be the inventor of the device, but not the role of Jagadis Chunder Bose.
>From the very beginning Marconi was mired in controversy regarding his claim. The question was reconsidered in the early 1990s by Phillips (1993), who concluded that Marconi did not invent the detector that he claimed to have developed. However, Phillips was unable to locate the true inventor of the so-called "Italian navy coherer". The mystery was resolved in a paper by Probir Bandyopandhyay, who provided convincing evidence that the real inventor of this device was Jagadis Chunder Bose, Professor of Physics at Calcutta University (Bandopadhyay, 1998). The device is described in a paper that appeared in the Proceedings of the Royal Society (Bose, 1899). In fact, somewhat earlier, Bose had developed what seems to be the world's first solid state diode detector for radiation and presented his findings at the Royal Society, London, on January 28, 1897. A report of this presentation appeared in the Proceedings of the Royal Society (Bose, 1897).
The centennial of this last paper was celebrated in a special section attached to the special edition of the proceedings of the Institute of Electrical and Electronic Engineers commemorating the fiftieth anniversary of the invention of the transistor (IEEE, 1998). The papers by Bose, as well as that of Phillips, are reproduced in that publication. A brief summary of these developments appears in Mervis and Bagla (1998).
We find it extraordinary that Hong is apparently unaware of the IEEE publication. Although Hong does cite Phillips's paper, we find that he does so in a somewhat misleading way and makes only cursory references to Bose. In particular, he does not refer to the crucial papers of Bose cited above.
We hope you find these observations useful. We believe that they not only serve to debunk the claims of Marconi's priority, but also to provide another illustration of the fact that inventions do occur without the protection of intellectual property.
Sincerely yours,

The report debunks all the made-up numbers used by the big media firms to direct U.S. antipiracy policy. The blog post is worth reading, and post a comment if you can figure out how to access the report. (There is link to scribd, but that site appears to be unusable.)
