英文摘要:
We study decentralized protection strategies against Susceptible-Infected-Susceptible (SIS) epidemics on networks. We consider a population game framework where nodes choose whether or not to vaccinate themselves, and the epidemic risk is defined as the infection probability at the endemic state of the epidemic under a degree-based mean-field approximation. Motivated by studies in behavioral economics showing that humans perceive probabilities and risks in a nonlinear fashion, we specifically examine the impacts of such misperceptions on the Nash equilibrium protection strategies. We first establish the existence and uniqueness of a threshold equilibrium where nodes with degrees larger than a certain threshold vaccinate. When the vaccination cost is sufficiently high, we show that behavioral biases cause fewer players to vaccinate, and vice versa. We quantify this effect for a class of networks with power-law degree distributions by proving tight bounds on the ratio of equilibrium thresholds under behavioral and true perceptions of probabilities. We further characterize the socially optimal vaccination policy and investigate the inefficiency of Nash equilibrium.

中文摘要:
我们研究了针对网络上易感感染易感(SIS)流行病的分散保护策略。我们考虑一个种群博弈框架,其中节点选择是否接种疫苗,流行病风险定义为基于度的平均场近似下流行病流行状态下的感染概率。受行为经济学研究表明人类以非线性方式感知概率和风险的推动,我们专门研究了这种误解对纳什均衡保护策略的影响。我们首先建立了一个阈值均衡的存在性和唯一性,其中度大于某个阈值的节点接种疫苗。当疫苗接种成本足够高时,我们发现行为偏差会导致较少的玩家接种疫苗,反之亦然。我们通过证明行为和真实概率感知下均衡阈值比率的紧界,量化了一类具有幂律度分布的网络的这种影响。我们进一步刻画了社会最优疫苗接种政策,并研究了纳什均衡的无效性。
