文摘

We model trading interactions of money and commodities/services in a network of agents with dyadic interactions. The results obtained agree very well with published data of wealth distribution in different countries and price distribution. One striking result is the effect of trust in trading relations. Trust reinforces trading transactions, and helps to make society more even and the distribution of wealth is fairer. This model allows us to predict that the fundamental features in trading are the freedom to change prices and the importance of trust in dyadic interactions.
