Due to their ties with elected leaders, central bankers may pursue pol
icies that are not in society's best interests. Consequently, the rela
tionship between the public and the central bank can be characterized
as a principal-agent problem. An inflation and stabilization bias aris
e as a result of this agency problem and the magnitudes of these biase
s depend on the political environment. Various institutional proposals
for eliminating these biases are examined, and we find that central b
ank independence and performance contracts work best. However, we argu
e that central bank independence is preferable for resolving the agenc
y problem.
