Performance Evaluation of Multicast Cost Sharing Mechanisms
In this paper we investigate experimentally the performance of Marginal Cost (MC) and Shapley Value (SH) mechanisms for sharing the cost of multicast transmissions. We implement a...

Analysis of Multi-Actor Policy Contexts Using Perception Graphs
Policy making is a multi-actor process: it involves a variety of actors, each trying to further their own interests. How these actors decide and act largely depends on the way the...
