demurrage charge: As used herein, a charge made by the sponsor to spur the use of the Millennium Dollars® in commerce. The demurrage charge would be announced in advance, thereby encouraging people to spend their MR$ before the payment of the charge comes due. In effect, this is meant to be a counterweight to Gresham’s Law, where people may be hoarding the private currency as “good money” that holds its value better than the government-issued currency. Such hoarding is not good for society, since it reduces employment, as well as reducing trade and tax revenues. In addition, the sponsor requires a certain volume of monetary conversions in order to fund the operating costs of the liquid-payment market, which preserves the present value of the assets securing the issuance of the private currency. By spurring trade in MR$, monetary conversions would presumably increase. If the announcement of the demurrage charge has the desired effect of spurring trade, then the charge itself could be waived by the sponsor before it comes due.
