The Mutual Credit Currency System, this most radical form of endogenous money, was evaluated and compared with Marx’s Commodity-Money-Commodity requirement.  A simple simulation of a small community closed loop economy was used to illustrate the functioning of two types of mutual credit currency systems. The first, dubbed MCSG, behaved according to the specifications and recommendations of the mutual credit currency system’s founding fathers, Riegel and Greco. The second, dubbed the Komoko Monetary System, or abbreviated to KMS, was a sub-type of the mutual credit currency system with some additional restrictions and one additional liberty. The main restriction introduced in the KMS was that it almost exclusively supported the exchange of only newly produced goods and services. The liberty introduced is forecast-based credit allocation. It was shown that the MCSG has an inconsistency that could potentially lead to instability. The restrictions applied within the KMS can provide a remedy for this potential flaw, while at the same time rendering the KMS compliant with Marx’s requirement. The monetary control measures applicable in KMS were discussed, which guarantee robustness and stability and make KMS a true complement to the official fractional reserve banking.

Psychological factors influencing the use and development of Complementary Currencies

This paper presents a novel socio-psychological analysis of the motivations and experiences of mutual credit members in the United Kingdom and in the United States. Primary data comprised of interviews and participant observation, supplemented with secondary data analysis of organisation documents, and a review of the literature in psychology, sociology and economics. Group members were motivated to secure personal resilience against hardship, and the personal agency that results from this, along with the experiences of community and cultural identity positioning, motivates engagement. Consequently these groups are defined as cultural communities offering personal resilience to members through informal reciprocity. This approach, which prioritises the social aspects of exchange, has implications for the design of complementary currencies, particularly mutual credit initiatives, and demonstrates the value of engaging with the fields of psychology and sociology in developing interdisciplinary understandings of alternative economic practice.

A Report from Vermont (USA): The VBSR Marketplace

This paper described and evaluates a  peer to peer mutual credit system now in operation in the State of Vermont. It is called the VBSR Marketplace and is an innovative partnership between a statewide membership association, Vermont Businesses for Social Responsibility (VBSR) and a currency design and management organization, Vermont Sustainable Exchange (VSE). This project is a significant step forward in the community currency world as it makes participation in a mutual credit system a membership benefit for businesses that belong to an already existing and well-established business association.

Mutual Credit Systems and the Commons Problem: Why Community Currency Systems such as LETS Need Not Collapse Under Opportunistic Behaviour

This paper analyses theoretically how the Mutual Credit System (MCS) is affected by the Commons Problem. The MCS is defined as a pure accounting system of exchange, of which the Local Exchange and Trading System is a real life example. The Commons problem is caused by the incentive of members to issue units without the intention to repay this ‘debt’. This can potentially cause an MCS to collapse. It is found that eight institutional design principles for overcoming the Commons problem can also be applied to the MCS. Moreover, the dynamic interaction of economically motivated members of the MCS is analysed. This yields the conclusion that the MCS can provide a robust and stable alternative to the Central Money Supply System, whilst preserving its important special feature of an endogenous supply of money.

Commodity Currencies for Fair and Stable International Exchange Rates

For the greater part of the history of money, we humans have used commodities as the basis of our currency systems. In 1971 the world went to a fiat currency system and the problems have increased. During the last 30 years the United States has seen a previously unheard of rate of bank failures. Since the early 70s labor wages have stagnated, corporate taxes have been shifted onto the individual, and the gap between the rich and the poor — countries and individuals — has escalated at similarly unheard of rates. This paper shows why fiat currencies are unworkable, why commodity currencies have also failed and how mutual credit systems may be the answer.
