“…Studies of the characteristics of the peer or cooperating group that influence the agent's decision to collaborate address the question of who to cooperate with or who cooperates with whom. The literature on Latin America shows that cooperation is conditioned by the political identity of mayors, geographical proximity and prior relations or social capital (Abrucio et al, 2013;Angnes et al, 2013;Mazzalay et al, 2006;Mazzalay, 2011;Mazzalay, 2016;Piterman et al, 2016;Rodríguez-Oreggia & Tuirán, 2006).
