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…
Exact conditions for evolutionary stability in indirect reciprocity under noise
Nikoleta E. Glynatsi, Christian Hilbe, Yohsuke Murase
Indirect reciprocity is a key mechanism for large-scale cooperation. This mechanism captures the insight that in part, people help others to build and maintain a good reputation. T…
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…
Indirect reciprocity with stochastic rules
Yohsuke Murase, Christian Hilbe
Cooperation is a crucial aspect of social life, yet understanding the nature of cooperation and how it can be promoted is an ongoing challenge. One mechanism for cooperation is ind…
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 direct reciprocity in group-structured populations
Yohsuke Murase, Christian Hilbe, Seung Ki Baek
People tend to have their social interactions with members of their own community. Such group-structured interactions can have a profound impact on the behaviors that evolve. Group…
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…
Social norms in indirect reciprocity with ternary reputations
Yohsuke Murase, Minjae Kim, Seung Ki Baek
Indirect reciprocity is a key mechanism that promotes cooperation in social dilemmas by means of reputation. Although it has been a common practice to represent reputations by bina…
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…
Local stability of cooperation in a continuous model of indirect reciprocity
Sanghun Lee, Yohsuke Murase, Seung Ki Baek
Reputation is a powerful mechanism to enforce cooperation among unrelated individuals through indirect reciprocity, but it suffers from disagreement originating from private assess…
Lockdowns need geographic coordination because of propagation of economic effects through supply chains
Hiroyasu Inoue, Yohsuke Murase, Yasuyuki Todo
In order to prevent the spread of COVID-19, governments have often required regional or national lockdowns, which have caused extensive economic stagnation over broad areas as the…
Do economic effects of the anti-COVID-19 lockdowns in different regions interact through supply chains?
Hiroyasu Inoue, Yohsuke Murase, Yasuyuki Todo
To prevent the spread of COVID-19, many cities, states, and countries have `locked down', restricting economic activities in non-essential sectors. Such lockdowns have substantiall…
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…
Five rules for friendly rivalry in direct reciprocity
Yohsuke Murase, Seung Ki Baek
Direct reciprocity is one of the key mechanisms accounting for cooperation in our social life. According to recent understanding, most of classical strategies for direct reciprocit…
Automata representation of successful strategies for social dilemmas
Yohsuke Murase, Seung Ki Baek
In a social dilemma, cooperation is collectively optimal, yet individually each group member prefers to defect. A class of successful strategies of direct reciprocity were recently…
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…
CARAVAN: a framework for comprehensive simulations on massive parallel machines
Yohsuke Murase, Hiroyasu Matsushima, Itsuki Noda +1
We present a software framework called CARAVAN, which was developed for comprehensive simulations on massive parallel computers. The framework runs user-developed simulators with v…
Conservation of population size is required for self-organized criticality in evolution models
Yohsuke Murase, Per Arne Rikvold
We study models of biological evolution and investigate a key factor to yield self-organized criticality (SOC). The Bak-Sneppen (BS) model is the most basic model that shows an SOC…
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…
An open-source job management framework for parameter-space exploration: OACIS
Yohsuke Murase, Takeshi Uchitane, Nobuyasu Ito
We present an open-source software framework for parameter-space exploration, named OACIS, which is useful to manage vast amount of simulation jobs and results in a systematic way.…
