Abstract

The issue of basics for successful functioning of a complementary currency has gained utmost importance in the recent years because of the crisis phenomenon in the world economic domain. In the discussed research, the focus has been put on the structural aspect of the problem with the network approach having been used as a theoretical background. During the initial stage of the research, a mathematical model of a local municipal economy has been engineered. Using this economic model and a number of other economic local system models, it has been revealed that closed exchange contours could be found in every modelled system. It has been found that the number of closed exchange contours in an economic system is greater than in the similar random or social system, and exactly these contours form a structural basis for system’s sustainability. To evaluate the effect of complementary currency introduction, an agent-based computer model has been coded. This computer model has proved the efficiency of complementary currency introduction. Complementary money supports functioning of the economy, and, in case of the lack of real money, can improve and speed up economic processes flowing in the system. The described results have been received while computer simulation with implementation of the agent-based computer model and have been verified through the experiments in the real local economic system.

Keywords

Agent-based computer model, closed contour, network approach, sustainability.

Complementary Currencies in Japan Today: History, Originality and Relevance

IJCCR

Since 1995 the number of experiments with complementary currencies in Japan has exploded. Not only is Japan the country in the world with the most systems in operation today, but also the nation with the greatest diversity of such experiments. The aim of this paper is to bring to light the strata of the heterogeneous Japanese schools of complementary currencies, and describe how they relate to each other. It provides a description of the different models used in each school, as well as their numbers and locations. Finally, the most original models are highlighted, and the relevance of these experiments for the rest of the world is evaluated.
