We ask whether imposing fees on redeeming investors can prevent runs on money market mutual funds (MMFs) and related intermediation arrangements. We first show that imposing a fee only in extraordinary times often leaves the fund susceptible to a preemptive run where investors rush to redeem...

This paper studies the effects of introducing a Central Bank Digital Currency (CBDC) on economic output, bank intermediation and financial stability in a closed economy using an Agentbased Stock Flow Consistent (AB-SFC) Model. Thereby a digital bank run is simulated across various economic...

Theory suggests that in the face of fire sale externalities, banks have incentives to overinvest in order to issue excessive money-like deposit liabilities. The existence of a private market for insurance such as contingent capital can eliminate the overinvestment incentives, leading to...

The federal banking agencies—the Comptroller of the Currency, the Federal Reserve Board, and the Federal Deposit Insurance Corporation—supervise. They work cooperatively with banks and their remedial powers are so extensive they rarely use them. Oversight is designed to proceed through...
