The decline of local economies has become more serious in recent years. The reason for the widening regional disparities is the drain of people, goods, and money from local economies. Community currencies are considered to be a possible solution to the problem of regional disparities. However, it is rare for a community currency to succeed in local revitalization. The “community currency game” aims to elucidate the effects of local revitalization through experimental trading using a community currency. In this paper, we present a community currency game that aims to increase understanding of the mechanism by which the prisoner’s dilemma affects the behavior of consumers in a local economy. The community currency game “Online Shopping.com” consists of three mini games. The first is the “silent trading game”, the second is the “conversational trading game”, and the third is the “conversational trading game with community currency”. In game 3, we found that most participants chose the town stores. Also, the gross domestic product of the town (total amount purchased in the town) increased. Through the three games, we learned that community currencies have the power to allow participants to escape from the prisoner’s dilemma.

社区货币游戏“ Online Shopping.com”：囚犯的困境和当地经济中的消费者行为

近年来，当地经济的下滑已变得更加严重。区域差距扩大的原因是当地经济体的人员，货物和资金流失。共同体货币被认为是解决区域差异问题的一种可能方法。但是，很少有社区货币能够成功实现本地复兴。“社区货币博弈”旨在通过使用社区货币进行实验性交易来阐明当地振兴的影响。在本文中，我们提出了一种社区货币博弈，旨在加深对囚徒困境影响当地经济中消费者行为的机制的了解。社区货币游戏“ Online Shopping.com”包括三个迷你游戏。首先是“无声交易游戏”，第二个是“会话交易游戏”，第三个是“社区货币交易游戏”。在游戏3中，我们发现大多数参与者选择了城镇商店。此外，该镇的国内生产总值（在该镇购买的总金额）增加了。通过这三场比赛，我们了解到社区货币有能力让参与者摆脱囚犯的困境。
