Network-mediated competitive pressures. Peer comparison affects strategic behavior. Heterogeneity creates asymmetries. Related but Paper 1 more financial, Paper 2 more epidemiological.
Agents care about their performance relative to connected peers. Relative performance concerns create strategic interdependencies through network links. Risk-taking behavior adjusts based on peer comparisons. Network topology determines how competitive pressures propagate. This peer comparison mechanism affects equilibrium asset prices through aggregated strategic adjustments.
view paper→Cooperation and disease transmission coevolve through network structure. Structural heterogeneity creates leverage points - highly connected hubs adopt protection due to amplified risk, catalyzing cooperation. Cost heterogeneity creates weakest links - low-risk individuals free-ride and act as disease reservoirs, undermining cooperation. Heterogeneity is double-edged: influence asymmetry facilitates cooperation, motivation asymmetry degrades it.
