The current stable-NAV model for prime money market funds exposes fund investors and systemically important borrowers to runs like those that occurred after the failure of Lehman in September 2008. This working paper, by the Squam Lake Group, argues that, to reduce this risk, funds should have...

In recent years, U.S. banks have increasingly relied on deposits from financial intermediaries, especially money market funds (MMFs), which collect funds from large institutional investors and lend them to banks. In this paper, we show that intermediation through MMFs allows investors to limit...
