First Micro-Simulation Model of a LEDDA Community Currency-Dollar Economy

Results are presented for a first-in-class microsimulation model of a local-national currency system. The agent-based, stock-flow consistent model uses US Census income data as a starting point to project the evolution of local currency (community currency) and dollar flows within a simplified county-level economy over a period of 28 years. Changes in the distribution of family income are tracked. The community currency system under investigation is the Token Exchange System (TES), a component of the larger Local Economic Direct Democracy Association (LEDDA) framework under development by the Principled Societies Project. The model captures key design features of a TES, and results suggest parameter ranges under which the simulated TES is capable of achieving stated aims. Median and mean take-home family income more than double during the simulation period, income inequality is nearly eliminated, and the un- employment rate drops to a 1 percent structural level. The need for more sophisticated modeling of a TES, and avenues of future research, are discussed.

Is A Global Virtual Currency With 
Universal Acceptance Feasible?

As digital goods and services become an integral part of modern day society, the demand for a standardized and ubiquitous form of digital currency increases. And it is not just about digital goods; the adoption of electronic and mobile commerce has not reached its expected level at all parts of the globe as expected. One of the main reasons behind that is the lack of a universal digital as well as virtual currency. Many countries in the world have failed to realize the potential of e-commerce, let alone m-commerce, because of rigid financial regulations and apparent disorientation & gap between monetary stakeholders across borders and continents. Digital currency which is internet-based, non-banks issued and circulated within a certain range of networks has brought a significant impact on the development of e-commerce. The research and analysis of this paper would focus on the feasibility of the operation of a digital currency and its economic implications.

Taking Moneyless Exchange to Scale: Measuring and Maintaining the Health of a Credit Clearing System

Every day brings reports of new financial crises and financial malfeasance within the banking and financial establishment. In an effort to keep the banking system functioning, the largest banks and financial institutions have been relieved by national governments of tremendous amounts of their bad debts, shifting that burden onto the shoulders of the citizenry. At the same time, governments are imposing austerity upon their citizens in order to reduce the extremity of their budget shortfalls. Clearly, the global system of money and finance contains structural flaws that must be recognized and transcended. Reform is very unlikely to come in time to avert widespread social, political, economic, and environmental disasters. That leaves it to citizens, businesses, and communities to take action on their own behalf to ameliorate the negative effects of the failing system. Parallel systems of exchange and finance are both necessary, and easily implemented at the local and regional level. The most effective approach is the process of direct clearing of credits amongst buyers and sellers. This credit clearing process, which is being used in such systems as LETS and commercial trade exchanges, enables the creation of local liquidity based on local production, avoiding the use of conventional money and bank borrowing and moving local economies toward resilience, independence, and sustainability. The focus of this article is on credit clearing as a local exchange option, and deals specifically with the proper allocation of credit within credit clearing exchanges. It explains the causes of (1) the “pooling” of credits, (2) stagnation of circulation, and (3) failure to thrive, it prescribes policies to be applied in credit allocation, and it describes metrics that are important in assessing the performance of individual member accounts and in monitoring the overall health of a credit clearing system. Further, it explains the distinction between private credit and collective credit and the role of each in facilitating moneyless exchange, and recommends procedures for preventing excessive negative and positive balances while enabling both saving and investment within the system.

Improving Complementary Currency Interchange By A Regional Hub-Solution

Groups involved in complementary currencies (CC’s) that push for an interchange between their member-currencies are not yet a favourite subject in the existing CC-grassroots movement. One reason could be the existing doubts of activists that such structures might be non-transparent, support instability, raise corruption or be a gate for the comeback of the ruling system of limitless inequality. On the other side, an interchange could open bigger markets, add more diversity or raise the number of participants above a critical number for long term survival. The authors present the case of the region of Zurich, Switzerland, where a council of different CC-organizations was founded. As a result a new software platform cc-hub was developed to bundle regional LET systems. The platform is based on the open source Online Banking software, Cyclos, and covers many possible needs of a regionally or purpose-linked network of CC’s. It is able to support interchange, improve the efficiency of clearing and help to build up the necessary resilience for long term stability. It could serve as a model for cooperation between small neighbouring CC’s, for organizational improvement and additional economical benefit. But to verify such benefits will be a subject of further research.

Complementary Currency Open Source Software in 2010

This report briefly covers the field of non-commercial mutual credit software, discussing the issues and challenges the projects collectively faced in meeting the needs of the movement. There is a clear cultural divide between commercial barter software which helps businesses exchange spare capacity within the law, and free open source projects which help neighbours to exchange under the radar of the tax man. There is almost no cross-fertilisation between nonprofit, idealistic, community projects, and the business barter. The aims of both cultures are very different, though their methods are similar.
