Lecture 8 (Evolutionary theory) Flashcards
Two evolutionary approaches
-Population ecology > Oranizational ecology > industry level
-Theory of evolution > evolutionary economics > firm level
Population ecology 3 main concepts
- Carrying capacity
- Niche partitioning
- Inertia
Carrying capacity meaning
Maximum load of firms given the scarce resources
Niche partitioning meaning
The environment is shared in various areas to give room for all
members, which are selected by natural selection
Inertia meaning
Evolution from generalists to specialists, it is slow, difficult, and often
unsuccessful
Theory of evolution focus
Focus on genes which evolve over time and are selected out by the environment or transmitted to
offspring
VSR principle
Variation of a given species
Selection of the fittest variants
Retention of heredity (features retained and passed on)
Evolutionary economics focus
focuses on firm evolution, drawing upon assumptions made by the Behavioural Theory of the Firm. It explains this evolution by applying the VSR principle
Evolutionary economics assumptions
-Incomplete information
-Bounded rationality
-Satisfying rather than optimizing
Two types of searches:
-Exploitation - firms refine existing processes
-Exploration - firms try out new ideas
Organizational Ambidexterity meaning
Balance between exploitation and exploration, they must co-exist
Factors driving variation in theory of evolution
-prior routines
-information available & bounded rationality
-satisfying rather than optimizing
selection meaning in theory of evolution
misfit firms go bankrupt
retention or inheritance meaning in theory of evolution
today’s choices are rooted in past choices
Lamarchian explanation of evolutionary theory
the inheritance of acquired
characteristics and the principle of use and disuse (those parts of a body that are used grow larger. Those parts that are not used tend to wither away)
