This paper proposes that bank runs are unique equilibrium outcomes instead of
self-fulfilling prophecies. By assuming that depositors make their withdrawal
decisions sequentially, the model provides an equilibrium-selection mechanism in
the economy. A bank run would occur if and only if depositors perceive a low
return on bank assets. Furthermore, a panic situation arises only when the
market information is imperfect. A two-stage variant of the model shows that
banks would deliberately offer a demand-deposit contract that is susceptive to
bank runs.
