Abstract
Decision-makers often rely on external sources for their information such as
consultants, real estate agents, or “helpful sales agents. In politics, decision
makers often rely in information from interest groups.
This paper ana-
lyzes how much the decision-maker can learn from such interested parties—
informants who themselves have a stake in the decision to be made.
I show that the information provider has an incentive and the ability
to withhold some information if he is not known to be fully informed.
Since the decision-maker learns about some states of the world but never
about others, learning from interested information providers is asymmetric.
Applying the results to the problem of delegation, I show that it a legislature
can elicit more information from interest groups when it delegates the
decision to a bureaucrat while constraining the bureaucrat’s discretion. The
paper thus extends the theory of delegation by endogenizing bureaucratic
expertise, recognizing that the latter is, at least in part, the result of
voluntary information revelation by interest groups.
