Abstract Using an agent-based model to study the success of product-sampling campaigns that rely on information about social networks, this paper investigates essential decisions which consumers and how many them target with free product samples. With unweighted a weighted real-world personal communication network, we show decision is more important than target. Use network increases profits by at least 32 percent. Companies should use high-degree targeting heuristic identify most...
