Title: The Inner Circle Revisited


1
The Inner Circle Revisited

Introduction
  • Michael Useem (1984) The Inner Circle
  • Linked Politics and Interlocking Directorates
  • Multiple Directorships Political Leadership
  • Limitations
  • statistics cross tabs
  • no controls
  • The Puzzle Multiple directorships correlate with
    a lot of important characteristics of
    corporations and directors, but which
    characteristics most important?

3
Purpose of this paper
  • Untangle the correlations in Inner Circle What
    are the most important forces driving corporate
    interlocking?
  • Apply p model/exponential random graph (ERG)
    model to corporate network.

4
Structure of this paper
  • Overview of The Inner Circle theory (and
    related hypotheses)
  • Brief introduction to ERG (p) models
  • Preliminary results

5
The Inner Circle What drives interlocks/multiple
directorships?
  • Not collusion, power/influence, cooptation.
  • Instead desire for business scan
  • Scan Information on business environment
    (including politics)
  • business scan gives directors/corporations
  • class-wide perspective
  • status within corporate community
  • Inner Circle Directors with multiple
    directorships

6
The Inner Circle What drives interlocks/multiple
directorships?
  • Directors with multiple positions (Inner Circle)
    overrepresented in
  • political donations
  • business associations
  • media
  • arts bodies
  • Entry to Inner Circle increased by
  • Exclusive schools upper class, family, networks
  • Businessmen's Clubs upper class, networks
  • Wealth/Family upper class, stockholding

7
Main Hypotheses
  • H1 Politics Politically active firms have
    greater interlocking.
  • Think tanks
  • Business Association Executives
  • Government Boards
  • Political Donations
  • H2 Status Firms with high status directors have
    greater interlocking.
  • Directors in Whos Who

8
Main Hypotheses
  • H3 School Firms with exclusive school graduates
    have greater interlocking.
  • School attendance from Whos Who
  • H4 Clubs Firms with members of top
    businessmens clubs have greater interlocking
  • Club membership from Whos Who
  • H5 Wealth/Family Firms with wealthy directors
    have greater interlocking
  • Rich 200 List (publication)

9
Secondary Hypotheses
  • H6 Geography
  • H6a Firms in same region have greater ties to
    firms in the same region (homophily)
  • State of firm headquarters
  • H6b Firms in dominant economic region have
    greater interlocking (activity).
  • H7 National/Foreign
  • H7a Local firms have greater interlocking with
    other local firms (homophily).
  • H7b Local firms have greater interlocking
    (activity).

10
Secondary Hypotheses
  • H8 Corporate Liberalism Theory Politically
    moderate firms have greater interlocking.
  • Donation to both major parties (bipartisan
    donors)
  • H9 Political Factions Politically moderate
    (conservative) firms have greater interlocking
    with other politically moderate (conservative)
    firms (homophily)
  • Donation to conservative parties only vs
    bipartisan donors

11
Secondary Hypotheses
  • H10 Regulation Companies which are highly
    regulated have greater interlocking.
  • H11 Publicly Listed Companies which are
    publicly listed have greater interlocking.
  • H12 Revenue/Size Larger firms have greater
    interlocking.

12
Exponential Random Graph (ERG or p) models
  • Also called p models or ERGMs
  • For more
  • Harrigan 2007. An introduction to ERG models for
    corporate networks. On Politics and Interlocking
    Directorates Research Community website
  • http//sna.pl/politicsandinterlocking/

13
ERG (p) models
  • Key ideas of ERG models
  • We can model the fundamental building building
    blocks of graphs (generative).
  • Building blocks are small sub-graphs. For
    example
  • edge
  • triangle
  • edge between two attributes
  • Sub-graph is called a configuration.
  • Relationship between each sub-graph
    (configuration) and an observed graph (our
    network) can be expressed as a number (parameter)

14
Specifications for Experiment
  • Software PNet (Robins, Pattison and Wang
    University of Melbourne). Both user friendly and
    efficient (handles large networks, lots of
    functionality).
  • See also Harrigan 2007, PNet for Dummies.

15
Specifications for Experiment
  • Non-directed network Ties formed by
    Non-Executive Directors serving on two or more
    board of the 250 Largest Corporations in
    Australia (2006)
  • Structural Configurations
  • star effects rich get richer
  • triangle effects friend of a friend
  • isolates tendency for isolated nodes
  • 27 Attributes with two configurations for each
    activity and homophily
  • Covariate network Executive Directors network

22
Results
  • Structural Parameters
  • edges interlocks rare
  • isolates large number of isolates
  • k-star marginally significant and ve
  • popularity is not an organising principle
  • reverse unpopularity is an organising principle
  • k-triangle significant and ve
  • artefact of 2-mode gt 1-mode (control)
  • core-periphery driven by transitivity
  • small number of highly networked directors An
    Inner Circle

23
Results
  • Activity Effects
  • Revenue ve marginally significant
  • information and prestige for directors
  • large corporations have the means to recruit
    highly interlocked directors
  • Business Association Execs ve marginally
    significant
  • inner circle tied to the leadership of business

24
Results
  • Activity Effects
  • Whos Who ve significant
  • inner circle tied to high status individuals
  • School ve significant
  • inner circle tied to upper class
  • Club ve significant
  • inner circle tied to other important social
    networks

25
Results
  • Activity Effects
  • No effect on activity of
  • Australian vs foreign
  • Regulated vs unregulated
  • Listed vs private
  • Geography
  • Think Tanks
  • Govt Boards
  • Executive Directors Network

26
Results
  • Activity Effects
  • Political Donations -ve significant
  • donations require autonomy
  • donations crude form of influence
  • donations liability as well as benefit
  • highly networked firms more to loose
  • less networked firms more to gain by donations
  • Eg. National Australia Bank vs Ethanol Producer

27
Results
  • Activity Effects
  • Wealthy directors -ve significant
  • Similar pattern in British data
  • Why?
  • wealth as independent source of power, interlocks
    not necessary to gain social capital or
    influence?
  • interlocks interfere with power of wealthy?
    Scrutiny and unwanted influence over family
    business?
  • rich lists sensitive to new wealth with fewer
    interlocks?

28
Results
  • Homophily Effects
  • Listed Firms Community? Expertise?
  • No effect of
  • Political donations/factions
  • Australian vs Foreign
  • Geography
  • Regulation
  • Wealth/Director capital
  • Heterophily (opposites attract/hierarchy)
  • School
  • Government board
  • Number of NEDs on board
  • ( tendency for clubs, revenue, etc.)

29
Heterophily School Attendance
30
Results
  • Why heterophily?
  • Low status firms gain from upwards
    interlocking,
  • But why do High status firms engage in these
    interlocks?
  • avoiding conflicts of interest?
  • limited number of positions and directors
  • ambitious directors need low status boards
    because so few positions at the top
  • top corporations need to recruit directors from
    lower status firms because so few top directors.

31
Conclusions
  • Interlocking driven by
  • Director characteristics (vs corporate)
  • Small number of high status directors
  • Upper class network effects are strong
  • Centre of business politics and policy
  • business associations.
  • Heterophily High and Low status firms
  • limited board size and directorships
  • Political donations
  • crude form of power/influence that is avoided by
    the most networked corporations
  • Wealthy directors
  • wealth opens its own doors?
  • Interlocks constrain the power of wealthy?

32
Further Research
  • Bipartite networks (director/corporation)
  • Longitudinal (causality)
  • Social Influence p models (attributes)
  • Covariate networks
  • stockholdings
  • industry input/output monopoly/concentration
    (constraint)
  • debt, banks
  • Attributes
  • profit
  • lobbying
  • Full network 2000 corporations, 10,000 directors
  • Anglo-saxon and/or European comparisons
