“…We assume that the epidemic is fast relative to 6 For more related literature, see the excellent discussion in Toxvaerd (2020). Galanis (2020) study in a static model the potential to use social proximity, and within-group random testing and anonymous notification of positive cases as a tool to induce social distancing. 7 See, however, Rowthorn and Toxvaerd (2017) for a problem of managing an infection in an SIS model (where recovered can become infected again) with homogenous population and no risk of infection-induced mortality.…”

“…the probability of being infected by j if all i's neighbors had active links to j. As a result, bδ n−1 ≥ (1 − λ)θ(1 − φ)(1 − σ ij )L ≥ (1 − λ)θ(1 − φ)φ n−2 L which, again from (9), implies that in a collection of isolated cliques where every node has n − 1 active links no node wants to cut a link. As a result, a collection of isolated cliques with n members must be stable.…”

“…As a result, a slow intervention is always dominated by a fast one. In contrast, in the largest 9 Optimality requires that n-member cliques should acquire a new member whenever the benefit from an additional active link bδ n is larger than θ(1 − φ). However, for λ = 0 (i.e.…”

“…In the smallest equilibrium, cliques tend to be too small relative to the social optimum. 9 In this case, even an intervention causing full crowding out always increases welfare. In contrast, in the largest equilibrium there are typically too many active links and the intervention will typically exacerbate a situation of excessive risk taking.…”
