Lecture 6 Flashcards
What are stylised facts?
Empirical observations which date identified in a small number of observations
If these stand up to imperial testing then they become established facts
E.g observing an Apple fall from a tree
What conditions must be met for one theory to be accepted over another
Be consistent with an existing set of observations
Be consistent with new/ other observations
What are the stylised facts of industry evolution
Occasionally new industries are born These can have major impacts on the wider social and political system Schumpeter New change leads to structural change New skills Knowledge
What is the relevance of kondratiev waves o ILC
Illustrate the rise and fall of economic fortunes
Steam engine, rail, electrical engineering, auto, it
All waves show
Prosperity recession
Depression
Improvement
Takes approx 55yrs
What is an invention
A new/ novel engineering or scientific discovery that is commercially applied in the form of a new product or service
The first firm to do this is the radical innovator
What is diffusion
The degree of economic and social impact is determined by the extent to which the invention diffuses across society
In this process many incremental innovation occur
Tell me about s shaped diffusion curves
Inflection point
Exponential growth up to inflection point
After we see a slowing down in the rate of adopters
M is the maximum potential adopters which is affected by social norms, laws and customs
M can be challenging to to estimate if the product is radical
Normal distribution explains up until inflection point
What are the 6 stylised facts of ILCs
Product diversity peaks and falls
A rise and fall in the number of new market entrants
Over time producers devote increasing effort to process innovation and less to product
The most recent entrants account for a disproportionate share of product innovations
Shake out- the number of of producers grows, peaks and declines steadily despite growth in industry output
Rate of change Olof the market shares of largest firms slows and leadership of the industry stabilises
What does vernon argue
The country of CA changes as the product matured and competition changes
Shows how the comparative advantage of production shifts between countries
Combines both demand and supply to explain international trade patterns
Dynamic approach
Recognised the mobility of factors and firms across national borders p
What are some important assumptions of Vernons model
Information and knowledge are critical factors for the creation of radical new products
Inputs needed to produce the good changes over time
Market size and structure also play a role in determining patterns
What is vernons model of globalisation
Over time the competitive advantage of production changes. The basis for this is the theory of international trade
As products mature both the optimal production location and sales changes
An exporter may become a net importer as the product standardised
Could be the same firm that moves cross borders
What is Abernathy and utterbacks explanation
Link innovation patterns to development of industry structure
Initially highly competitive but becomes an oligopoly in maturity
What is the dominant design explanation
New technologies have different options and ideas
One design comes to dominate
Explains the closure of innovative capacities
Opens up a link between product and process innovation
What is Abernathy and utterbacks 3 stage model
Stage 1
High degree of uncertainty and fluidity
Uncertainty ends with emergence of a dominant design
Major market shakeout occurs amongst firms who develop alternative losing designs
Stage 2
Shift in competitive focus to cost competition and process technologies
Process innovation enables firms to exploit scale economies and there may be another shakeout
Stage 3
Maturity
Relative homegenity amongst firms
Focus on innovation is a gradual process
What strategy predictions can be derived from Abernathy and utterbacks
Firm should evaluate safe of its life cycle and if
In takeoff- engage in radical product
In growth- engage in radical process and incremental product
If in maturity - engage in incremental process and product
What difference do gort and keeper have
Do not support the dominant design hypothesis
What does Klepper argue
What drives industry is ongoing process innovation
Firms differ with R+ D capabilities
R+D knowledge is cumulative and difficult to imitate by others
Profit fed back into more process R+D and the most innovative firms ultimately win
What is the relevance of the R+D learning curve
As R+D costs fall, firms become better at process R+D
Virtuous cycle exists between R+D- sales - profit and growth
Path dependence- successful past innovators are more likely to be successful innovators in the future
How does Rogers say the diffusion curve can be explained
Look at various traits
3 variables governing adoption behaviour
Personality
Socioeconomic
Communication
What are the 5 categories of adopters
Innovators Early adopters Early majority Late majority Laggards
What are the strategy predictions of demand side
Need to target different user types at different stages of the ILC
Key for successful diffusion of a new technology product is the targeting of new adopters
What are the 3 main limitations of ILC
Existence of niches
Does not consider late entry
Reverse life cycles
What are the implications of multiple niches
Assumes each firm has one target type
Each consumer type has a given preference set
Each consumer can switch membership
Is dominant design a special case?
More common is multiple niches
Each nice contains a distinct consumer type
What are the implications of niches
Need to understand consumer groups
Do consumers face switching costs?
Firms can create stable market niches by innovating to specific groups
E.g transport sector and sub markets
