• The most fundamental resource in the modern economy is knowledge and the most important process is learning.
• Knowledge-based economy: increase of the relative importance of knowledge inputs in the production process.
• Knowledge & firms: the creation of knowledge is the essence of building of competitive advantages in firms
Knowledge as an Economic Resources
![Page 15: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/15.jpg)
Economics of Information
Information is an unusual economic good because:
If I give or sell a piece of information to you, I still have it (non-rivalry).
It is either very difficult or impossible for me to prevent you from passing onthe information to someone else (non-excludability).
These features of information complicate the economics of information:
The fixed costs of producing information can be spread over all of the users thatmight be willing to pay for it without incurring significant additional costs(increasing returns)
The willingness of individuals to pay for information is limited because a) itscost of reproduction are small and b) having it does not assure exclusive access(market failure and free rider problems)
Intellectual property rights are a limited solution, but create the economic distortionof monopoly
![Page 16: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/16.jpg)
Distinction between Information and Knowledge
The peculiar features of information do not fully apply to knowledge:
1. If I know something, I may not be able to transfer that knowledge to you.Information alone is not enough to reproduce knowledge.
2. In particular, my knowledge may consist of information that can be reducedto rules and procedures and tacit capabilities that I cannot effectively reduceto rules and procedures. (This leads to the division of knowledge into two types
codifiable (or articulable) and tacit.) Whether I will ‘codify’ knowledge that can be codified depends on the incentives (economic or social) for doing so.
3. In addition, even if I can reduce something I know to rules and proceduresyou may not have the contextual knowledge or experience to understand my rules
and procedures (absorptive capacity).
4. The existence of tacit or ‘unarticulable’ knowledge reduces the relevance of the problems with information as an economic good, but it raises additionalproblems in the transfer or exchange of knowledge.
![Page 17: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/17.jpg)
• Know-what, knowledge about facts or principles
• Know-who, knowledge supporting indirect access to knowledge
• Know-how, knowledge linked to skills
• Know-why, knowledge about principles and laws andthe capacity to solve problems and extend the knowledge
This taxonomy is an hierarchy with an increasing amount of tacitknowledge and difficulty in codification as you proceed down the list.
A Taxonomy of Knowledge-types
![Page 18: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/18.jpg)
Economic Considerations About the Boundary Between Codifiable and Tacit Knowledge
The extent to which knowledge is codified is determined by incentives: the costs and benefits of doing so.
To examine the costs and benefits of codification, the knowledge environment should be examined. In first approximation you can have stable or changing contexts.
A stable context is characterised by the fact that codification can proceeds on the basis of pre-existing languages and models (a partial solution to the ‘absorptive capacity’ problem).
� In a changing context languages and models are fluid and codification is costly.
� In stable knowledge environments codification has lower costs and higher benefits than in unstable environments
Whether information and communication technologies are making the codification process less costly and therefore more extensive is an issue of considerable economic and policy significance.
Note that if the environment is changing more rapidly over time, information technology cost saving may be offset or eliminated.

Determinants of innovation
• Economic factors (supply and demand) are important for an understanding of the rate and direction of technical change
• Chance and unpredictability can be important in the process
• There are forward and backward feedbacks throughout the process of innovation
![Page 22: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/22.jpg)
Innovation supply
Supply of an innovation determined by– state of the relevant scientific and technological
knowledge (technological opportunity) – cost and availability of inputs to innovation
(trained technicians, knowledge workers, appropriate equipment)
– ability to capture the increased profit from innovation (appropriability)
![Page 23: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/23.jpg)
Innovation demand
Demand for a potential innovation depends on – Amount of cost reduction from that innovation
(process innovation; new sources of supply; organizational change)
– Consumer or producer benefit from something new (product innovation)
– Consumer or producer benefit from improvement in an existing good (incremental product innovation)
![Page 24: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/24.jpg)
Direction of innovation - supply
• Lack of technological opportunity– Science/technology not always available
• Research on nanotechnology in 1910s, but lack of instrumentation – waited for electron microscope to make progress
– Many wants unsatisfied for an extended period of time• cure for AIDS • Malaria vaccine• lightweight electric batteries
![Page 25: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/25.jpg)
Direction of innovation - supply
– Treatment of diabetes held up by complexity of understanding insulin
• Appropriability considerations– Lack of patents directs invention towards
secrecy
![Page 26: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/26.jpg)
Direction of innovation - demand
• “Inducement mechanisms and focusing devices” (Nathan Rosenberg)– Importance of bottlenecks in choice of
innovative activity - “compulsive sequences,” where there is an imperative need for improvement
– Manufacturing feeds back to innovation– Shocks to relative prices of inputs
![Page 27: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/27.jpg)
Relative factor prices
Sharp changes in relative prices• Focuses attention on particular costs
– firms cannot innovate in all directions at once– Oil price shocks and fuel-efficient cars
• Threat or actual withdrawal of – labor
• strikes in mid-19th C Britain lead to labor-saving machines
– source of supply• Cotton to UK in U.S. Civil War (economizing on inputs)• US dye industry developed to replace German in WW I• Southeast Asian rubber during WW II – leads to creation of synthetic
rubber

The linear model of innovation
A useful conceptualization, but not the whole story. The idea:science base � basic research � applied
research � invention � prototype � development � commercialization � diffusion� technical progress � economic growth
Sometimes the entire process in red is referred to as innovation
Which stages need funding, and how?
![Page 29: Lecture 1 - Knowledge, technological change and Innovation Studies](https://reader034.vdocuments.us/reader034/viewer/2022051608/545634adaf79590b088b4c55/html5/thumbnails/29.jpg)
Modifying the linear model• Importance of backward links (reverse the

Innovation and learning
• During the R&D process– Knowledge concerning laws of nature (basic R)– Knowledge with useful applications (applied R)– Knowledge directed towards optimal design
characteristics and satisfying consumer wants (development)
• After the R&D process– During manufacturing – learning by doing– During the use of the product – learning by using

Beyond simple metaphors…Research Programmes on Technology and Innovation
Points of Departure
– From markets to incentives for rational and identical agents and then to innovation
– From agents (firms with asymmetrical capabilities) to markets and innovation
– From structural incentives (production system characteristics) to incentives and innovation dynamics
– Additional Questions:– What is the driving force behind asymmetrical capabilities (codified
knowledge, corporate structures, core competences, networking…)– Stylized facts and the level of theorizing [general trends and valid
metaphors: product cycle, waves, critical technologies, paradigms etc.)
