We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … generosity with a sequence of dictator games conducted in the field. We find that networks of different dimensions differ … substantially in density, clustering, and centrality. When relating generosity to networks we observe that social distance only …

On the contrary, the economics approach is very precise in explaining why networks emerge but …
