"...the obvious solution is not merely to foster the use of transferable product-specific vouchers as stores of value but to make them company-specific and include expiry dates on them. Businesses that issue them could then be confident about the level of sales they can achieve before the end of the expiry period. This is where we go, roughly speaking, if we follow the ingenious Digital Coin proposal of Paul Grignon, a Canadian film maker whose excellent animated documentary Money as Debt deserves to be screened to all students of economics.
Grignon’s plan is available in summary form in its own must-see animated video. It appears to be a way of simultaneously overcoming both Say’s Law and the problems of the Bartercard concept. From the standpoint of scholars of the evolution of Keynes’s General Theory of Employment, Interest and Money, Grignon’s proposal amounts to using modern technology to replace an ‘entrepreneur economy’ with a ‘co-operative economy’ (see Keynes’s Collected Works, Vol. XXIX, pp. 77-80). This is because workers and other suppliers of inputs used by a company accept payment for their inputs in the form of claims on the output to whose production they have contributed. Since they cannot be sure what they can exchange these claims for in terms of claims on outputs of other firms, they are sharing the risk of the business with the owners of the business."
"...I find Grignon’s Digital Coin proposal especially well thought out. The time for this self-issued credit system to be implemented seems ripe both because of the failure of the existing bank-credit system and because we now have the technology to make it work."
