110 Financial Reporting and Transparency in Corporate Governance
to achieve these goals—especially the latter—has been the
subject of considerable research, with the distinction between
outside and inside directors being the most commonly
examined dimension of board structure.
Corporate boards typically consist of both outside
and inside directors.

For example, in a broad sample of
U.S. rms that were publicly traded between 1990 and 2004,
Linck, Netter, and Yang (2008) found 67 percent to be the
median percentage of outside directors on a board. Outside
directors are typically experienced professionals, such as
CEOs and executives of other rms, former politicians and
regulators, university deans and presidents, and successful
entrepreneurs. e value of having outside directors on the
board derives, in part, from their broad expertise in areas
such as business strategy, nance, marketing, operations,
and organizational structure. Further, outside directors can
bring an independence that carries with it an expectation of
superior objectivity in monitoring management’s behavior.
eir diligence in this respect may stem partially from the
monetary incentives associated with serving as a director
(Yermack 2004), but possibly even more important may be
their desire to enhance, cultivate, and protect their signicant
personal reputational capital.
Inside directors, who are typically executives of the rm, can
facilitate eective decision making because they are a valuable
source of firm-specific information about constraints and
opportunities (see, for example, Raheja [2005], Harris and Raviv
[2008], and Adams, Hermalin, and Weisbach [2010]). As Jensen
and Meckling (1992) note, the allocation of decision (or control)
rights within an organization is a fundamental building block of
organizational structure. And because it can be costly to transfer
information within the corporate hierarchy, it can be ecient
to assign decision rights to the individuals who possess the
information necessary to best make decisions, even in the face of
agency conicts (Aghion and Tirole 1997). In addition to their
decision-making responsibilities, inside directors can also be
particularly helpful in educating outside directors about the rm’s
activities (Fama and Jensen 1983). Inside directors, who typically
hold relatively large amounts of the rm’s stock and options, as

Pursuant to Item 470(a) of Regulation S-K of the U.S. Securities and
Exchange Commission, rms must disclose whether each director is
“independent” within the denition prescribed by the exchange on which the
rm’s shares are traded. Directors are typically classied as insiders, outsiders,
and aliates (or gray directors). Insiders are current employees of the rm,
such as the CEO, CFO, president, and vice presidents. Outsiders have no
aliation with the rm beyond their membership on its board of directors.
Aliates are former employees of the rm, relatives of its CEO, or those who
engage in signicant transactions and business relationships with the rm as
dened by Items 404(a) and (b) of the regulation. Directors on interlocking
boards are also considered to be aliated, where interlocking boards are
dened by Item 402(j)(3)(ii) as “those situations in which an inside director
serves on a non-inside director’s board.”
well as have their human capital tied to the rm, may also have
stronger incentives than outside directors to exert eort and to
maximize shareholder value.
At the same time, however, inside directors are potentially
conicted in their incentives to monitor because of their lack of
independence from the CEO and a desire to protect their own
private benets.

Further, even though well-informed outside
directors are likely to be more eective in advising the CEO,
insiders may be reluctant to share their information if it will
be used to interfere with the CEO’s strategic decisions (Adams
and Ferreira 2007). is scenario is particularly true if the
information could be used to discipline the executives or to
curtail their private benefits.
Holmstrom (2005, 711-2) provides a succinct charac-
terization of the issues related to information ow between
management and outside directors:
Getting information requires a trusting
relationship with management. If the board
becomes overly inquisitive and starts questioning
everything that the management does, it
will quickly be shut out of the most critical
information flow—the tacit information that
comes forward when management trusts that
the board understands how to relate to this
information and how to use it. Management will
keep information to itself if it fears excessive board
intervention. A smart board will let management
have its freedom in exchange for the information
that such trust engenders. Indeed, as long as
management does not have to be concerned
with excessive intervention, it wants to keep
the board informed in case adverse events are
encountered. Having an ill-informed board is also
bad for management, since the risk of capricious
intervention or dismissal increases.

However, see Drymiotes (2007) for a situation in which an increase in
the number of inside directors might actually improve the eciency of the
board’s monitoring role. In his model, outside directors have an incentive to
shirk their monitoring duties and to shortchange the CEO with respect to
his performance ex post. Inside directors, who represent the CEO’s interests,
can commit themselves to expending monitoring eort ex post, thereby
increasing the CEO’s incentive to exert productive eort.
Outside directors can bring an
independence that carries with it an
expectation of superior objectivity in
monitoring management’s behavior.
