实物货币与数字货币：一种产生差异的差异
Physical versus digital currency A difference that makes a difference
摘要
This paper compares digital and physical currency, focusing on a single intrinsic difference: digital, unlike physical currency, allows the monetary authority to trace the monetary flows in and out of the accounts. We show that this technological advance in recordkeeping can be used by the monetary authority to improve upon physical currency and achieve efficiency in a wide range of circumstances.
