The paper draws a sharp distinction between organizations and institut
ions. Organizations are agents like households, firms, and states that
have preferences and objectives. Institutions are formal and informal
social constraints (rules, habits, constitutions, laws, conventions)
which apparently reduce the total scarce resources available. Economis
ts debate whether organizations are individuals with their own objecti
ves, or whether they are artificial things created ultimately to serve
the objectives of their members. In contrast, economists debate wheth
er institutions are real schemes which define the cognitive ability of
the agent, or whether they are the subject of optimization rationalit
y and, hence, are nominal social constraints.
