The Social Accumulation of Knowledge
The mere production of knowledge does not guarantee that otherswill be able to exploit that knowledge (Polanyi; Mokyr)
Tacit Knowledge
Trade Secrecy
Intriguingly, the ability to provide private incentives to produceknowledge that can be exploited by others is a the heart of moderntheories of endogenous growth (Romer)
Open Science and Patenting are two institutional arrangementsthat require the disclosure of knowledge (Dasgupta and David)
By and large, the spheres of knowledge governed by Open Scienceand Patenting are assumed to be relatively independent

Disclosure of Perfume“Anyone who cracks the code to know just how molecules of a certainformation produce a certain smell is liable, not only to advance basic humanknowledge, but also to gain a great deal of money.” (Turin, 2003 )
• Knowledge of perfume highly scientific - grounded in a complex mix of
organic chemistry, studies of the olfactory system but also useful -however two distinct disclosure strategies exist in parallel.
• Three Nobel Prizes for “perfume” in the last century• Wallach, 1910 - essential oils, including terpenes, were previously a mysterious field now
presented clearly in experimental as well as in theoretical respects, “must be regarded asone of the greatest triumphs which chemical science has celebrated”
• Ruzicka, 1939 – for the investigation of very large number of important polyterpenes
which included many “ odora ” occurring in musk and civet, muscone and civetone.• Noyori, 2001 - concerns molecules that occur in two forms that are mirror images of each
other - two forms often have totally different effects on cells e.g. the receptors in ournose. One form of the substance limonene smells like lemons, while its mirror imagesmells like oranges.

Nobels vs. NosesHigh levels of disclosure grounded in patents and
publicationsKnowledge of perfume highly scientific - grounded in organicchemistry, studies of the olfactory system etc.
In 1887, German scientist, Albert Bauer accidentally discovered
the organic molecule for musk & patented it. He also went on tosynthesize derivatives – musk xylene, musk ketone etc. (in ChanelNo. 5).
Scientists began to elucidate rules linking structures to smell: e.g.to smell musky macro-cycle ring must have 14-18 members. Bothnew molecules and synthetic pathways are patented & published.
Japanese scientist, Ryoji Noyori (academic & industry scientist),shared the 2001 Nobel Prize in chemistry for the “asymmetric”synthesis of new molecules such as menthol (> 400 publications &> 100 patents)
At the Takasago plant for ( – )-menthol synthesis(February, 1984). K.Tani, H. Takaya, R. Noyori, S. Otsuka, S. Akutagawa,and H. Kumobayashi.

Secrecy also widespreadHigh levels of secrecy with very limited disclosure,
strongly fought secrecy and mythical status of knowledge
Highly formalized training e.g. InternationalSuperior Institute of Perfume, Cosmetics and
Food Aromas, Paris.Individual “noses” who create the perfume“recipes” are highly paid but secretive(although their claim on royalties is subject tolegal challenge – so credit is complex)
Tacit learning – often family links among
“noses”Also scientific – 2004 Nobel Prize fordescribing how odor-sensing proteins in thenose translate specific tastes and smells intoinformation in the brain

The Disclosure of Knowledge in Pasteur‟s Quadrant
A given piece of new knowledge may simultaneously have potential as agreat scientific discovery and as an important source of commercialreturns
Multiple potential disclosure outcomesNo systematic disclosures (Secrecy)
Patenting (Commercial Science)
Scientific Publication (Open Science)
Both Patenting and Scientific Publication (Patent-Paper Pairs)
A disclosure strategy is the choice among these disclosure choices, and will be grounded in the microeconomic, strategic, and institutional environment in which knowledge is funded, developed and diffused

Scientific Researchers andPrivate Research Investors
Regardless of potential commercial returns, scientific researchers realizebenefits from knowledge disclosure through scientific publications
Intrinsic preferences for kudosSignaling to both private and public employers
Regardless of potential impact on the scientific community, privateresearch investors realize benefits through the protection of ideasFormal intellectual property rights (patents)Trade secrecy and inimitability
Researcher preferences for scientific disclosure may conflict with the
commercial objectives of research fundersMay be willing to trade of wages for ability to publish in the scientificliterature
Disclosure strategy results from the contract between researchers and research funders when bargaining over compensation

http://slidepdf.com/reader/full/gms-disclosure-strategy-080806 12/31
The ModelSingle researcher is hired by a single firm in order to produceknowledge that potentially has significant scientific value and/orcommercial returnsThe firm‟s expected return from the innovation depends on their ability to limit potential competition
Relative to secrecy, a patent grant increases the fixed cost of entry ( l) However, disclosures through patenting ( d PAT ) or publication ( d ) reduce thefixed cost of entry
The researcher cares about their monetary compensation ( w) andtheir ability to earn “kudos” through publication ( bs)The disclosures requires for patenting and publication may beindependent of one another (low-fidelity) or completelyoverlapping (high-fidelity)

Consider a potential entrant who faces the following profitfunction
l is the strength of patent protectionb E is the reduced marginal cost of entry due todisclosures d and d PAT
q is distributed uniformly on [0,1]p + b
E < 1 (entry always uncertain)
The potential for entry is increasing in both patenting andpublication disclosure, while the cost of entry is increasingin the receipt of a patent

Two key expressions shape the decision of whether to allowscientific disclosure, patenting, or produce patent- paper pairs…
Consider the choices that maximise surplus
Scientific disclosure? … consider the ratio of the marginal
benefit versus marginal cost of scientific disclosures.Choose no disclosure if
Patent?… consider the ratio of the marginal benefit to themarginal cost of publication…choose to patent if

Strategic OverlapSuppose that the knowledge published could be chosen andrelated to the knowledge disclosed through patenting.
No cost to same disclosures as in patent, so CommercialScience does not arise.
If choose to publish and patent disclosure requirements arelow, then worthwhile patenting even if it would otherwiseencourage entry; so no Open Science

IP Protection Through DisclosuresBaseline model: IP protection increases entry costs
Suppose workaround not guaranteed to „work‟Entrant sinks costs, l , and generates probability, 1 – r , that
will still be excluded.Expected entrant profit:
Expected firm profit:
Marginal cost of publication falls when you have a patent

The Anti-Commons EffectFear that patent thickets will deter scientific research
Murray and Stern (2006) found that papers with patentsattached attracted fewer citations
Assume that patent protection alters scientific kudos:

DynamicsSuppose that scientists and firms live two periods
Overlap with other generations
Past knowledge reduces future capital costs, k
Full transfer (under contracting): zero future costsPartial transfer (through publication): (1- d t -1)k
Firm owns patent and can license it to next generation
Disclosure, fee & wages now a 3-way negotiationUse Nash bargaining solution
Past publication gives future pair an easier work-around if there is no license – work-around possible (on same researchpath) with probability r .

License NegotiationsOutcomes
If no patent, t = 0
If patent but no publication, t = k /3
If patent but publication, t = k (1-(1- r )d t -1
)/3
Patent-Paper PairsFor d sufficiently high, patent-paper pairs can be anequilibrium
Presence of patent reduces incentives for publication and viceversa when r < 1
Increasing r causes more disclosure under patent-paper pairs

Other implicationsLook only at symmetric dynamic equilibria
Inter-temporal complementarityOnly worthwhile publishing if expect future scientific work to
be published (so can earn a citation)Therefore, always exists a commercial science or secrecyequilibrium.
Domain of open science is expanded as a result of substitutability

ConclusionsThe disclosure strategy of privately funded research is grounded in thedisclosure environment and is shaped by the bargaining over disclosurebetween scientific researchers and their funders
Rather than an anomaly, patent-paper pairs emerge as an equilibrium
outcome in which scientific researchers trade off wages in order to gainscientific credit, while investors (private or public) seek to retain theability to capture value from these “dual - purpose” discoveries
Interestingly, in most circumstances, increases in the strength of formalintellectual property protection enhances the scope for patent-paper
pairs.More generally, the model suggests that the key requirements forcumulative disclosure in the aggregate requires a careful evaluation of the strategic foundations of disclosure strategy.
