We find that the topology of transfer networ ks violate some of the predictions of both models. We then generalize the m odel of pure altruism to include caps on transfers that represent transacti on costs\, liquidity constraints\, and social norms. Even with a parsimonio us parametrization\, the generalized model predicts equilibrium networks wi th topological features that match closely those of intra-village transfer networks in rural Gambia. Using a simulation-based indirect inference appro ach\, we estimate the structural parameters of this model\, relying only on income data and the topology of the transfer network for identification. W e test for the existence of binding caps on transfers and find that network topologies are consistent with strong caps on transfers. Our structural es timates confirm that kinship is a strong predictor of altruistic preference s. We corroborate our structural estimates using proxies for transaction co sts from surveys.\\n\\nContact: Gaëtan Fournier : gaetan.fournier[at]univ- amu.frEvgeny Tsodikovich : evgeny.tsodikovich[at]univ-amu.fr\n\nPlus d'inf ormations: https://www.amse-aixmarseille.fr/fr/evenements/simon-hess LOCATION:Îlot Bernard du Bois - Salle 23\, AMU - AMSE\, 5-9 boulevard Maur ice Bourdet\, 13001 Marseille URL;VALUE=URI:https://www.amse-aixmarseille.fr/fr/evenements/simon-hess CONTACT:Gaëtan Fournier : gaetan.fournier[at]univ-amu.frEvgeny Tsodikovich  \;: evgeny.tsodikovich[at]univ-amu.fr TRANSP:OPAQUE END:VEVENT END:VCALENDAR
