How altruism works: An evolutionary model of supply networks
Zehui Ge,Zi-Ke Zhang,Zi-Ke Zhang,Zi-Ke Zhang,Linyuan Lü,Linyuan Lü,Tao Zhou,Tao Zhou,Ning Xi +8 more
TL;DR: In this article, the authors developed an evolutionary decision-making model to characterize the effects of suppliers' altruism in supply networks, and find that the performances of both suppliers and supply chains are improved by introducing the role of altruism.
Maximum entropy model for business cycle synchronization
TL;DR: A pairwise maximum entropy model is used to analyze the business cycle synchronization of the G7 economic system and obtains a pairwise-interaction network, which exhibits certain clustering structure and accounts for 45% of the entire structure of the interactions within the G8 system.
Power-law distributions in circulating money: effect of preferential behavior
TL;DR: In this paper, preferential behavior was introduced into the study on statistical mechanics of money circulation and the computer simulation results showed that the preferential behavior can lead to power laws on distributions over both holding time and amount of money held by agents.

Cultural evolution: The case of babies’ first names
Ning Xi,Zi-Ke Zhang,Zi-Ke Zhang,Yi-Cheng Zhang,Yi-Cheng Zhang,Yi-Cheng Zhang,Zehui Ge,Li She,Kui Zhang +8 more
TL;DR: In this paper, the authors employ the historical data on baby names from the United States to investigate the evolutionary process of culture, in particular focusing on how inequality among baby names changes over time.
The economic mobility in money transfer models
Ning Ding,Ning Xi,Yougui Wang +2 more
TL;DR: In this article, the authors investigate the economic mobility in four money transfer models which have been applied into the research on wealth distribution and demonstrate the mobility by recording the time series of agents' ranks and observing their volatility.
