Deposit Insurance, Moral Hazard And The Risk Of Runs

The effectiveness of deposit insurance in eliminating panic runs varies with the size of coverage and the degree of supervisory involvement of the agency in charge of insurance. When the agency is not involved in the supervision of banks, partial insurance preserves the monitoring role of depositors and reduces the region for which runs occur, but it is unable of completely eliminating them. When the agency has a high degree of supervisory involvement, even with partial insurance panic runs disappear as the regulator's signal becomes more precise.
