Path creation and destruction in industries, regions, and firms Strengths and limitations of the concept of path dependence in innovation studies Path creation and destruction – C. Davis – ISRN – Vancouver - May 2004
agenda • Path dependent processes • Narrow and broad definitions of path dependence • Path dependence and increasing returns to scale • Agents and trajectory lifecycles • What does it mean to contribute to theory in this area of management and policy? Path creation and destruction – C. Davis – ISRN – Vancouver - May 2004
Polya urn process simulations • This simulation models only the internal dynamics of a Polya process (there is no competition from another system) • The feedback mechanism is the rule: Probability (Add Redt+1) = f (Proportion Redt) Balmann et al., 1996 Path creation and destruction – C.

Degrees of genetic determinism in path dependence • Antonelli • A state at time t that is predictable at time t-1 is past dependent • A state at time 1 that is predictable from the sequence of prior states at times t-n is path dependent Path creation and destruction – C.

Famous pathways 1: Matthew Effect "For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath." (Matthew 25:29) Path creation and destruction – C. Davis – ISRN – Vancouver - May 2004
Famous pathways 2: Noah Effect Severe environmental selection with some recovery Path creation and destruction – C. Davis – ISRN – Vancouver - May 2004
Famous pathways 3: Joseph Effect Seven fat years and seven lean years Path creation and destruction – C. Davis – ISRN – Vancouver - May 2004
Path dependence claims in social sciences (usually refer to Polya Urn processes of advantage accumulation) • Importance of specific sequences of events • Importance of specific timing of outcome-shaping events • Similar starting conditions yield a wide range of possible outcomes • Small or contingent events can have large consequences • Practical irreversibility • In economic systems, effects of increasing returns to scale (IRS) Path creation and destruction – C. Davis – ISRN – Vancouver - May 2004
Sources of increasing returns (Arthur, 1988) • Large set up or fixed costs such as R&D, distribution networks, brand names, or specialized position in a division of labor, which provide an incentive to recover investment over longer production runs. • Learning effects: investments in learning to operate and manage complex technology systems produce increases in efficient and effective actions and constitute a disincentive to change systems • Coordination effects (externalities) are the benefits that one receives when others adopt the same option. Standardization leads to decrease in coordination costs. • Adaptive expectations: individuals’ expectations about the future are based on their reading of the past (rather than on rational analysis), and these expectations can be self-fulfilling.

Externalities as positive feedback mechanisms (centripetal forces) in agglomeration processes • Pecuniary externalities • Market-mediated geographically proximate backward and forward linkages • Technical or non pecuniary externalities • Spillovers and untraded interdependencies • Location economies vs. urbanization economies Path creation and destruction – C.

Exploitation of IRS implies ability to leverage externalities: case of NB IT gazelles, 1999-2001 Gazelles have higher rates of product innovation and use innovation support infrastructure more intensely than non-gazelles Gazelles earn greater portion of IT revenue from recently-commercialized products than non-gazelles Gazelles have learned to tap sources of growth in distant markets Path creation and destruction – C.

conclusions • Path dependence goes beyond IRS phenomena • IRS and other factors are generating “black noise” in the business environment • Actors are boundedly rational at best • Many paths are possible: pathways are created by actors within constraints that they discover or impose on each other • It is easier to generate autoregressive models than to test them with real data.
