Title: Ecological Approaches
1Ecological Approaches
- Why are there so many kinds of organizations?
- Org ecologists explain how social, economic, and
political conditions affect the relative
abundance and diversity of organizations and
account for their changing composite over time - Empirically oriented Cumulative findings
2Ecological Approaches
- Three common observations
- Diversity is a property of aggregates of
organizations that has no analogue at the level
of the individual organization - Organization often have difficulty devising and
executing changes fast enough to meet the demands
of uncertain, changing environments - The community of organizations is rarely stable
3Ecological Approaches
- Research Focus
- Population and community levels
- Rates of founding and failure as diversity
- Population
- A set of organizations engaged in similar
activities and with similar patterns of resource
utilization - Forms as a result of processes that isolate or
segregate one set of organizations from another
4Ecological Approaches
- Organizational communities
- Functionally integrated systems of interacting
populations - The outcomes for organizations in any one
population are fundamentally intertwined with
those of organizations in other populations that
belong to the same community system
5Ecological Approaches
- Structural inertia theory vs critics
- Determinism and loss of human agency
- Determinism opposed to voluntarism or probablism
- Level of analysis
- Individual actions to organizations vs
- Individuals actions to organizational populations
- Changes in organizational populations
- Variation, selection, retention, and competition
6Ecological Approaches
- Assumptions
- Individuals do matter
- But individual cannot always determine in advance
which variations will succeed - Individuals have difficulty changing existing
organizations strategies and structures quickly
enough to keep pace with the demands of
uncertain, changing environments
7Demographic Process
- Traditional approach to founding and failure
- Individual traits?
- Managerial inexperience, incompetence, inadequate
financing? - Ecological approach
- Volatile nature of organizational populations and
communities - Focus on socio, economic, and political factors

9Structural Inertia Theory
- What is the main thesis of this theory?
- How does this theory view organizations?
- What are two main questions?
- 1) How changeable are organizations?
- 2) Is change beneficial for organizations?
10Structural Inertia Theory
- Organizations are relatively inert entities for
which adaptive response is not only difficult and
infrequent, but hazardous as well - Change in individual organizations are viewed as
contributing less to population-level change than
organizational founding and failure
11Structural Inertia Theory
- Organizational ecologists focus on the influence
of organizational and environmental factors on
rates of organizational changes, as well as the
survival consequences of different kinds of
changes
12Structural Inertia Theory
- Selection processes explain change in
organizational populations - Inertia is viewed as consequence of selection
processes, not antecedent - Organizations with inert features are more likely
to survive
13Structural Inertia Theory
- Core and Periphery Structure
- Core features have higher levels of inertia,
lower levels of change - Organizations may change change
- Inertia relative to environmental change
- Structures of organizations have high inertia
when the speed of reorganization changes in core
featuresis much lower than the rate at which
environmental conditions change
14Age and Size Dependence in Rate of Organizational
Change
- Organizational age and size resistant to change
- But could organizations be fluid with age and
size?
15Fluidity with Age and Size
- But could organizations be fluid with age and
size? - Singh et al (1988)
- Discontinuous pattern of org change
- Left-censored organizations
- Theoretical support
- Internal complexity, differentiation,
specialization are associated with the adoption
of innovation (Haveman, 1993) - Slack resource theory
- Size and market power
-
16Repetitive Momentum
- Organizations history of change (Amburgey and
colleagues) - Organizational learning routinizes change
- Repetitive momentum
- The tendency to maintain direction and emphasis
of prior actions in current behavior - Address a dynamic effect of prior change
- The likelihood of change high immediately after
each additional change, but declines with
increases in the time since that type of change
last occurRed -
17Future research on size and age
- Age and size reveal little coefficients
- Attention to how age and size affect rates of
change or the conditions under which fluidity,
inertia, or momentum will predominate - Use of more direct measures of the underlying
processes
18Is Change Beneficial?
- Relationship between core features and liability
of newness (Stinchcombe, 1965) - Attempting core change to survive produces a
renewed liability of newness by robbing an
organizations history of survival value - Reliability, accountability, legitimacy
undermined - Structural inertia theory predicts that
organizations may fail as a result of their
attempts to survive
19Organizational Change and Failure
- Organizations do not necessarily fail as a result
of their efforts to change - But they do not necessarily improve their
organizational survival chances, either - More research needed in
- Adaptiveness of organizational change
- Left-censored organizations
- Right-censoring problem
- On-going organizational performance
20Reconciling Adaptation and Selection
- Organizations appear to change frequently in
response to environmental change, and often
without any harmful effects - Rates of change are often not constrained by age
and size as predicted by structural inertia
theory - The evolution of organizational populations
shaped jointly by processes of selection and
adaptation and their interaction
21Organizational Learning
- How experiential processes shape organizational
survival - How ageing influences organizational failure by
modelling more directly experiential learning
constructs invoke by the liability of newness and
ageing hypotheses
22Organizations Operating and Competitive
Experience
- Learning curve
- Competency traps
- Exploration of new routines and exploitation of
old ones (March, 1991) - Experiential processes in organizational
adaptation and selection processes - Between-organization differences in learning
23Key Topics Key Variables Key Predictions Key Predictions
Organizational Founding Spatial heterogeneity Variation in social, institutional and economic conditions across regions produce unobservable region-specific proneness to experiencing the founding of particular organizational forms Variation in social, institutional and economic conditions across regions produce unobservable region-specific proneness to experiencing the founding of particular organizational forms
Entrants similarity to incumbents Avoidance of direct competition pushes entrants away from similar organizations, while complementary differences pull them together agglomeration economies pull entrants toward competitors Avoidance of direct competition pushes entrants away from similar organizations, while complementary differences pull them together agglomeration economies pull entrants toward competitors
Age Dependence Organizational age Liability of newness failure rates decline with age as roles and routines are mastered and links with external constituents are established Liability of newness failure rates decline with age as roles and routines are mastered and links with external constituents are established
Liability of adolescence failure rates rise with age until initial buffering resource endowments are depleted, then decline with further increase in age Liability of adolescence failure rates rise with age until initial buffering resource endowments are depleted, then decline with further increase in age
Liability of obsolescence failure rates increase with age as their original fit with the environment erodes Liability of obsolescence failure rates increase with age as their original fit with the environment erodes
Liability of senescene failure rates increase with age as internal friction, precedent and political pacts accumulate, impending action and reliable performance
24Key Topics Key Variables Key Predictions Key Predictions
Size Dependence Organizational size Liability of smallness failure rates decline with size, which buffers organizations from threats to survival Liability of smallness failure rates decline with size, which buffers organizations from threats to survival
Structural Inertia Organizational change Change structural inertia increases as organizations age and grow, lowering rates of organizational change Change structural inertia increases as organizations age and grow, lowering rates of organizational change
Failure the failure rate increases after a core change, but then declines with the passage of time the disruptive effects change increase (decrease) with organizational age (size) Failure the failure rate increases after a core change, but then declines with the passage of time the disruptive effects change increase (decrease) with organizational age (size)
Organizational Momentum Cumulative organizational change The rate of an organizational change of the same type increases with the number of prior changes of the same type, but then declines with the passage of time since the last change of the same type The rate of an organizational change of the same type increases with the number of prior changes of the same type, but then declines with the passage of time since the last change of the same type
Organizational Learning Organizational operating experience Initial increases in operating experience lower failure rates as organizations move down learning curves for their routines, but further increases reduce responsiveness to changing environmental demands, raising failure rates Initial increases in operating experience lower failure rates as organizations move down learning curves for their routines, but further increases reduce responsiveness to changing environmental demands, raising failure rates
Organizational competitive experience The greater an organizations historical exposure to competition, the lower its failure rate
25Niche Width Dynamics
- Specialists vs Generalists
- Resource Partitioning
- In environments characterized by economies of
scale, competition among generalists to occupy
the center of the market where resources are most
abundant frees peripheral resources that are most
likely to be used by specialists - Increasing market concentration increases the
failure rate of generalists operating in the
center of the market and lowers the failure rate
of specialists operating at its periphery

of specialists operating at its periphery
27Population Dynamics and Density Dependence
- Population dynamics
- The number of prior foundings and failures in a
population - Density dependence
- The number of organizations in a population
28Elaborations of the Density Dependency Model
- Criticisms
- assumption (equal competition) questioned
- methodology questioned unobserved heterogeneity
in population - Weighted emphasis on generality
- Elaborations (Table 1.2.6)
- Legitimation and population
- Focus on organizational-level differences within
populations
29Density and Institutional Processes
- Cognitive
- Zucker (1977) institutionalization is a
cognitive phenomenon reflected in
taken-for-granted assumptions - Density dependence theory
- Emphasizes only cognitive legitimacy
- Legitimacy defies measurement focus on
observables - Indirect measurement vs direct measurement
- Legitimation variable or process?
30Density and Institutional Processes
- Sociopolitical
- Meyer Rowan (1977) and DiMaggio Powell (1983)
legitimacy is embedded in relational networks
and normative codes of conduct - Institutionalization as both a sociopolitical
process through which certain organizational
forms come to be regarded as obligatory, and as a
state in which organizational forms are
buttressed by legal mandate or by widely shared
cultural, professional and political norms and
values.
31Institutional Embeddedness and Sociopolitical
Legitimacy
- Baum Oliver (1992)
- Argues that density dependence model focuses
exclusively on cognitive legitimacy and
interdepencies among organizations within
populations and neglects the evolution of a
populations interdepencies with surrounding
organizations and institutions - Institutional embeddedness
- Interconnections between a population and its
institutional environment (Dimaggio Powell,
1983 Fombrun, 1986 1988)
32Institutional Embeddedness and Sociopolitical
Legitimacy
- Baum Oliver (1992)
- Relational density
- The number of formal relations between the
members of a population and key institutions in
the populations environment - Tests proxy-vs-process prediction
- Proxy view supported
- Ecological explanations of the underlying
institutional processes suggested
33Non-density-based Measures of Legitimacy
- Certification contests, certification,
accreditation, credentialing activities signal
reliability, raising the sociopolitical
legitimacy of organizational forms as well as
their cognitive legitimacy - Print media as basic source of information
diffusion
34Density and Competitive Processes
- Logic
- If all organizations in a population are not
equal competitors, then population density may
not provide the most precise measure of the
competition faced by different organizations in a
population - Localized competition
- Level of analysis
- Organizational niche overlap
-
35Localized Competition
- Organizations compete most intensely with
similar-sized organizations - The emergence of large organizations should be
accompanied by a decline in the number of
medium-sized organizations, while small ones
flourish as their most intense competitors are
removed from the environment - Size-localized competition may also play a role
in the consolidation of organizational
populations over time
36Localized Competition
- Localized competition models imply a pattern of
disruptive or segregating selection in which
competition between like entities for finite
resources leads eventually to differentiation - This mode of selection increases organizational
differentiation by producing gaps in the
distribution of the members of a population along
some organizational dimension
37Level of Analysis
- Location as a key factor
- Appropriate level of analysis selected
- Different levels of spatial aggregation imply
different assumptions about how general processes
of legitimation and competition unfold - Competitive processes in organizational
population may be heterogeneous, operating most
strongly in local competitive arenas - The greater the geographic segmentation of a
populations environment, the more geographically
localized competitive processes in the population
will be
38Level of Analysis
- The greater the geographic segmentation of a
populations environment, the more geographically
localized competitive processes in the population
will be (Carroll Huo, 1986) - Institutional and political constraints
- Nature of a populations activities
- Any thoughts on level of analysis?
39Organizational Niche Overlap
- Baum Singh (1994)
- Resource overlap model
- The potential for competition between any two
organizations is directly proportional to the
overlap of their targeted resource bases, or
organizational niches - Each member of a population conceived as
occupying a potentially unique organizational
niche that delineates its location in a
multidimensional resource space - Organizational niche the intersection of
resource requirements and productive capabilities
at the organizational level - Organizational niche is a result of adaptation
40Accounting for Concentration
- Common path
- Slow growth
- Rapid increase to a peak
- Decline in the number of population numbers
- Increased competition
- Density dependency model
- Project the shape of the growth trajectory
- Limited in explaining later decline in numbers
and increase in concentration - 5 elaborations
41Density Dependence Model
- Density delay
- Delayed population density effect
- Mass dependence
- Population mass the sum of the sizes of all
organizations in the population population size
weighted by organizational size - Competitive intensity
- The sum of the age x size interaction for all
population members
42Density Dependence Model
- Changing basis for competition
- Coupled clocks
- Density becomes decoupled from legitimacy and
competition as a population matures - Dynamic selection and scale-based selection
43Changing Basis of Competition
- Coupled-clocks
- Dynamic Selection and Scale-based Competition
44Population-level Learning
- Exploitation (individual organizations)
- Exploration (population-level)
- Levinthal and March (1993)
- the best strategy for any individual
organization is often to emphasize the
exploitation of successful exploration of others
45Population Operating and Competitive Experience
- An organization may be able to use other
organizations operating experience to improve
its efficiency - Advantages
- An organization has a limited ability to learn
- An organization has limited resources to
experiment - A great deal of variety without violating
internal or external standards of consistency and
reliability
46Key Topics Key Variables Key Predictions
Niche width Dynamics Specialist strategy Exploit a narrow range of resources and are favored in fine-grained and concentrated environments
Population Dynamics Generalist strategy Tolerate widely varying environmental conditions and are favored in coarse-grained, high variability environments
Prior foundings Initial increases in prior foundings signal opportunity, stimulating new foundings, but further increases create competition, suppressing new foundings
Prior failures Initial increases in prior deaths free up resources, stimulating new foundings, but further increases signal a hostile environment suppressing new foundings
Density Dependence Population density Initial increases in density increase the institutional legitimacy of a population, increasing foundings and lowering failures, but further increases produce competition, suppressing foundings and increasing failures
Population-level Learning Population operating experience An organizations failure rate declines as a function of the operating experience of its population at the time of its entry and of the populations increasing operating experience after the organizations founding
Population competitive experience An organizations failure declines as a function of its populations history of competitive outcomes at the time of its entry and of the populations increasing competitive experience after the organizations founding

- Why do organizations exist?
- Why are firms the same/different?
- What causes changes in organizations?
- Why do some firms survive and others dont?
