Evolution of cooperation in costly institutions exhibits Red Queen and Black Queen dynamics in heterogeneous public goods
https://doi.org/10.1038/s42003-021-02865-w
Public goods are often subject to heterogeneous costs, such as the necessary costs to maintain the public goods infrastructure. However, the extent to which heterogeneity in participation cost can affect groups’ ability to provide public goods is unclear. Here, by introducing a mathematical model, I show that when individuals face a costly institution and a free institution to perform a collective action task, the existence of a participation cost promotes cooperation in the costly institution. Despite paying for a participation cost, costly cooperators, who join the costly institution and cooperate, can outperform defectors who predominantly join a free institution. This promotes cooperation in the costly institution and can facilitate the evolution of cooperation in the free institution. For small profitability of the collective action, cooperation in a costly institution but not the free institution evolves. However, individuals are doomed to a winnerless red queen dynamics in which cooperators are unable to suppress defection. For large profitabilities, cooperation in both the costly and the free institution evolves. In this regime, cooperators with different game preferences complement each other to efficiently suppress defection in a black queen dynamic.

Why can spin glasses help us understand neural systems? Because they captured the key complexities related to memory, learning, and hierarchy. It was a revolution. Check this paper by Sompolinsky in PhysicsToday #sfiscience https://t.co/x6Yq8Sahyo
🦠💉 Seriously, how much vaccination is enough to reach herd immunity? How does the expected epidemic size depend on homophily in vaccine adoption?
🔗 arxiv.org/abs/2112.07538.
1) We find that already a small level of homophily (h) can considerably increase the critical vaccine coverage (πᶜᵥ) required for herd immunity and that stronger homophily can push this threshold entirely out of reach.
2) Our framework is general enough to account for homophily by adherence to other epidemic interventions that reduce the susceptibility or infectiousness of individuals, such as #social_distancing practices, use of protective equipment, and adoption of digital #contact_tracing.
3) Vaccines' efficacy against susceptibility or transmitting the infection can vary. For perfect vacc, the epidemic size increases monotonically as a function of homophily, while for vacc with limited efficacy, the epidemic size is max. at an intermediate level of homophily.

In this talk I will review the chronology of my works trying to find some logical explanation for the sequence of works I have done.
