The modularization of negotiating agents as proposed by the C-IPS approach provides a sound base for a concept that we call dynamic degrees of delegation. Agents following this concept enable their users at runtime to delegate particular subsets of decisions to their artificial agents. We extend our specification and implementation of fully autonomous agents to capture this concept. We have successfully implemented such a system for application in a sociological experiment.
