Acceptability, Means of Payment, and Media of Exchange


This essay explains the use of fiat money, or why intrinsically useless objects are accepted as payment in transactions. People accept a particular object as a means of payment because others do: social conventions matter more than the intrinsic characteristics of the object itself. Not everything can become a fiat money, though. If an object is especially costly to hold, for example, it will not be accepted as a means of payment. This explanation of fiat money is illustrated in a simple theoretical economic model.
