Stochastic ultimatum game: Spite-driven resource feedback fosters fairness
Arunava Patra, Prosanta Mandal, Sagar Chakraborty
The paper introduces a stochastic ultimatum game where offerers and responders negotiate over a self‑renewable resource, showing that high resource growth rates favor fairness whil…
Upstream reciprocity versus downstream reciprocity: Catalyzing cooperation
Vikash Kumar Dubey, Sagar Chakraborty
Why would anyone help a stranger, knowing they may never meet again? Indirect reciprocity offers one of the most compelling evolutionary answers, yet its two canonical forms -- ups…
Overcoming unfairness via repeated interactions in mini-ultimatum game
Prosanta Mandal, Arunava Patra, Sagar Chakraborty
Repeated interactions are ubiquitous and known to promote social behaviour. While research often focuses on cooperation in the Prisoner's Dilemma, experimental evidence suggests re…
Braess's paradox in tandem-running ants: When shortest path is not the quickest
Joy Das Bairagya, Udipta Chakraborti, Sumana Annagiri +1
Braess's paradox -- where adding network capacity increases travel time -- is typically attributed to selfish agents. Although eusocial colonies maximize collective fitness, we fin…
Collaboration drives phase transitions towards cooperation in prisoner's dilemma
Joy Das Bairagya, Jonathan Newton, Sagar Chakraborty
We present a collaboration ring model -- a network of players playing the prisoner's dilemma game and collaborating among the nearest neighbours by forming coalitions. The microsco…
Adaptive dynamics of eco-evolutionary repeated games: Effect of reward and punishment
Prosanta Mandal, Suman Chakraborty, Vaibhav Madhok +1
Long-term evolutionary processes can strongly influence common-pool resource conservation by generating new traits or behaviours that modify the feedback between population strateg…
