Conventional legal and economic analysis assumes that opportunistic behavio
r is discouraged and that cooperation is encouraged within firms primarily
through the use of legal and market incentives. This presumption is embedde
d in the modern view that the corporation is best described as a "nexus of
contracts, " a collection of explicit and implicit agreements voluntarily n
egotiated among the rationally selfish parties who join in the corporate en
terprise. In this Article we take a different approach. We start from the o
bservation that, in many circumstances, legal and market sanctions provide,
at best, imperfect means of regulating behavior within the firm. We consid
er an alternate hypothesis: that corporate participants often cooperate wit
h each other not because of external constraints but because of internal on
es. In particular, we argue that the behavioral phenomena of internalized t
rust and trustworthiness play important roles in encouraging cooperation wi
thin firms.
In support of this claim, we survey the extensive experimental evidence tha
t has been produced over the past four decades on human behavior in "social
dilemmas." This evidence demonstrates that internalized trust is a common
phenomenon, that it is at least in part learned rather than innate, and tha
t different individuals vary in their inclinations toward trust. Most impor
tantly, the experimental evidence indicates that decisions whether or not t
o trust others are in large part determined by social context rather than e
xternal payoffs. By altering social con text-subjects' perceptions of other
s' beliefs, expectations, likely actions, and relationships to themselves-e
xperimenters can reliably produce in subjects in social dilemmas everything
from nearly universal trust to an almost complete absence of trust. In oth
er words, most people behave us if they have two personalities or preferenc
e functions. One is competitive and self-regarding. The other is cooperativ
e and other-regarding Social framing is key in triggering when the cooperat
ive personality emerges.
These behavioral findings carry important implications for corporate law, F
or example, in this Article we demonstrate first that the phenomenon of tru
st offers insight into the substantive structure of corporate law and parti
cularly into the nature and purpose of that elusive legal concept, fiduciar
y duty. Second, the experimental evidence on trust sheds light on how corpo
rate law works, by suggesting that judicial opinions in corporate cases inf
luence corporate officers' and directors' behavior not only by altering the
ir external incentives but also by changing their internalized preferences.
This possibility helps explain the notoriously puzzling relationship betwe
en the duty of care and the business judgment nde, Third, trust highlights
the limits of law by explaining how cooperative Patterns of behavior can so
metimes develop within firms even when external incentives, such as legal s
anctions, are unavailable or ineffective. In the process, it underscores th
e dangers of the contractarian approach by suggesting that an excessive emp
hasis on external sanctions-including formal contract and even the rhetoric
of contract-may be not only ineffective but counterproductive, serving to
undermine trust and trustworthiness within the firm.
