Abstract : In this paper, we propose an agent-based analysis of a cumulative social-network game. Agents grant loans to their neighbours to maximize their intertemporal utility function. With a complete graph, we show that interest rates converge toward the theoretical equilibrium, even if ther is no centralized walrasian auctioneer and no preference transmition between agents. With a dynamic network, we explain why the network can't stabilize with a rational strategy. We introduce death and show that, even if the rational strategy is individually the best, the situation where three different strategies coexist is better for the global welfare.
