Network centrality → productivity through strategic complementarities vs cooperation-epidemic coevolution with heterogeneity. Both show heterogeneity affects strategic behavior but mechanisms differ.
An agent's position in a collaboration network determines their productivity. Higher network centrality increases output through strategic complementarities with connected agents. Activity in one domain (scientific) enhances productivity in another domain (technological), but this effect is asymmetric - the reverse direction shows no detectable influence.
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.
