Pundits have been predicting the death of cash for as long as the plastic card has been in existence – more than 60 years. This perception has been intensified of late by the rapid acceleration in payments innovation, driven in large part by the mobile phone, in both developed and developing...

We discuss the pros of adopting government-issued digital currencies as well as a supranational digital iCurrency. One such pro is to get rid of paper money (and coinage), a ubiquitous medium for spreading germs, as highlighted by the recent coronavirus outbreak. We set forth three policy...
