In this interview with a news site focused on information about digital currency, Miles Kimball fields questions on negative interest rates, differences between e-dollars and cryptocurrencies like bitcoin, and why good monetary policy still requires central banks. He says: “[I]t is fine to have private cryptocurrencies perform the medium-of-exchange and store-of-value functions of money, but monetary policy requires control over the unit of account. So central banks need to retain control over the type of money that defines the unit of account — in this case the e-dollar.”
