A model of local and global reciprocity
Mari Kawakatsu, Yohsuke Murase, Taylor A. Kessinger +1
We often decide how to treat friends based on observations of their past behavior, whereas actions toward strangers are typically guided by their public reputations. These two kind…
Editorial Trajectories in Wikipedia Reflect Underlying Hyperlink Structure
Yeonji Seo, Mi Jin Lee, Seung-Woo Son +2
Wikipedia hyperlinks have primarily been studied as navigational tools for readers, but their role in how information providers move between articles during editing remains less ex…
Incomplete Reputation Information and Punishment in Indirect Reciprocity
Heejeong Kim, Yohsuke Murase
Indirect reciprocity promotes cooperation by allowing individuals to help others based on reputation rather than direct reciprocation. Because it relies on accurate reputation info…
Indirect reciprocity under opinion synchronization
Yohsuke Murase, Christian Hilbe
Indirect reciprocity is a key explanation for the exceptional magnitude of cooperation among humans. This literature suggests that a large proportion of human cooperation is driven…
Costly punishment sustains indirect reciprocity under low defection detectability
Yohsuke Murase
Cooperation is fundamental to human societies, and indirect reciprocity, where individuals cooperate to build a positive reputation for future benefits, plays a key role in promoti…
Grouping promotes both partnership and rivalry with long memory in direct reciprocity
Yohsuke Murase, Seung Ki Baek
Biological and social scientists have long been interested in understanding how to reconcile individual and collective interests in iterated Prisoner's Dilemma. Many effective stra…
Evolution of global development cooperation: An analysis of aid flows with hierarchical stochastic block models
Koji Oishi, Hiroto Ito, Yohsuke Murase +2
Despite considerable scholarly attention on the institutional and normative aspects of development cooperation, its longitudinal dynamics unfolding at the global level have rarely…
A second-order stability analysis for the continuous model of indirect reciprocity
Sanghun Lee, Yohsuke Murase, Seung Ki Baek
Reputation is one of key mechanisms to maintain human cooperation, but its analysis gets complicated if we consider the possibility that reputation does not reach consensus because…
Deep learning based parameter search for an agent based social network model
Yohsuke Murase, Hang-Hyun Jo, János Török +2
Interactions between humans give rise to complex social networks that are characterized by heterogeneous degree distribution, weight-topology relation, overlapping community struct…
Friendly-rivalry solution to the iterated -person public-goods game
Yohsuke Murase, Seung Ki Baek
Repeated interaction promotes cooperation among rational individuals under the shadow of future, but it is hard to maintain cooperation when a large number of error-prone individua…
Sampling networks by nodal attributes
Yohsuke Murase, Hang-Hyun Jo, János Török +2
In a social network individuals or nodes connect to other nodes by choosing one of the channels of communication at a time to re-establish the existing social links. Since availabl…
Structural transition in social networks: The role of homophily
Yohsuke Murase, Hang-Hyun Jo, János Török +2
We introduce a model for the formation of social networks, which takes into account the homophily or the tendency of individuals to associate and bond with similar others, and the…
Stylized facts in social networks: Community-based static modeling
Hang-Hyun Jo, Yohsuke Murase, János Török +2
The past analyses of datasets of social networks have enabled us to make empirical findings of a number of aspects of human society, which are commonly featured as stylized facts o…
Multiplex Modeling of the Society
Janos Kertesz, Janos Torok, Yohsuke Murase +2
The society has a multi-layered structure, where the layers represent the different contexts. To model this structure we begin with a single-layer weighted social network (WSN) mod…
What does Big Data tell? Sampling the social network by communication channels
János Török, Yohsuke Murase, Hang-Hyun Jo +2
Big Data has become the primary source of understanding the structure and dynamics of the society at large scale. The network of social interactions can be considered as a multiple…
Modeling the role of relationship fading and breakup in social network formation
Yohsuke Murase, Hang-Hyun Jo, János Török +2
In social networks of human individuals, social relationships do not necessarily last forever as they can either fade gradually with time, resulting in link aging, or terminate abr…
A Universal Lifetime Distribution for Multi-Species Systems
Yohsuke Murase, Takashi Shimada, Nobuyasu Ito +1
Lifetime distributions of social entities, such as enterprises, products, and media contents, are one of the fundamental statistics characterizing the social dynamics. To investiga…
Multilayer weighted social network model
Yohsuke Murase, János Török, Hang-Hyun Jo +2
Recent empirical studies using large-scale data sets have validated the Granovetter hypothesis on the structure of the society in that there are strongly wired communities connecte…
