The Institutional Framework 171
sustainability of social norms, conventions, and other apparently unselfish
cooperative behavior not underpinned by third-party enforcement.

The
critical insights in the second approach are that, in many social interactions,
people make decisions based on what they expect others to do. Significantly,
some cooperative behavior appears to be sustainable only when it is self-
enforcing; that is, only when multiple individuals’ actions, based on their
expectations about others’ actions, are all mutually consistent with the joint
outcome.
Institutional innovations are feasible through the endogenous decisions
of individuals in collective settings. However, formal institutional changes
are often impeded without complementary and compatible changes of a
complex array of informal rules or social norms. In postindependence Latin
America, there was a proliferation of liberal institutional innovations – new
constitutions and legal codes, reorganizations of judiciaries, modernization
of monetary and fiscal institutions, and liberalization of sectoral economic
policies. A prominent question in the literature has been whether West-
ern European liberal ideas were or could be reshaped to fit these different
political environments. New institutional theory says it may not be straight-
forward. For example, it may not be possible to achieve the intended effects
from introducing Western European ideas of the individual right of prop-
erty or the U.S. institution of federalism without complementary and con-
sistent changes in social expectations. Furthermore, introducing foreign
institutions into Latin America’s distinct social environments could have
unintended consequences. Embedded social norms or other institutional
rigidities often prevent institutions from deviating far from preexisting ideas
and practices, thus making them path dependent and highly sensitive to
the critical historical moments of institutional formation. According to the
theory, institutional frameworks with radically different formative histories
might never converge, even if one is observed to be superior to another.
Stanley Engerman and Kenneth Sokoloff, using this theoretical con-
cept, offer an alternative endogenous explanation for the persistent insti-
tutional divergence of Latin America and the United States – one that
departs from conventional culturally deterministic explanations.

Their
main insight is that the institutional divergence was associated with key
