Peer-to-peer file sharing communities present a paradox for standard public goods theory, which predicts that free-riding should preclude the success of the community. We present a model in which users choose their level of sharing, downloading, and listening in the presence of sharing costs and endogenous downloading costs. In our model, sharing emerges(More)
An experimental structure is demonstrated that represents end-use customers in electricity markets who can substitute part of their usage between day and night. Each customer's demand relationship is represented by a two-step value function for each period, disaggregated from observed market demand relationships, that varies between day and night and during(More)
Robert Thomas has shown, using simulations of experimental results, that the power flow on any line in an electric network is linearly proportional to the total system load when that system is optimally dispatched using accurate generator cost data. By comparison, when offers from generators obtained in a wholesale market that is not perfectly competitive(More)
– How line flows, capacity requirements and system design might be altered under deregulated market structures is explored through simulations of experimentally-obtained loads and generator dispatches under alternative market structures, including a regulated base-case dispatch. Eight generators were located on the Power Web 30 bus simulated transmission(More)
An experimental structure is demonstrated that represents end-use customers in electricity markets who can substitute part of their usage between day and night. Individuals' demand relationships are represented by a two-step value function for each period that are disaggregated from observed market demand relationships. Demand varies between day and night(More)
