A set of agents is organized in a social network, which conveys synergies in two activities. Each agent has one unit of a resource to allocate between two activities. We show that individual choices are shaped by Bonacich centrality measures and an attractiveness multiplier. The latter, combined with the elasticity of Bonacich centrality with respect to the intensity of interaction, drives the sign of the network reaction to a modication of the costs of activities.
