"Awrey reframes Gresham’s Law for the technological age. In its original formulation, Gresham’s Law notes that good and bad money cannot circulate together. . . . For now, non-bank consumer money remains a small part of the picture. But as it proliferates, risks will emerge. To stay ahead of them, Dan Awrey’s book, Beyond Banks, is worth the read."---Marc Rubinstein, Net Interest
