What is A Marketplace for Spatio-temporal Resources and Truthfulness of Its Users about?

In this paper we propose a platform called Spatio-Temporal rEsources Marketplace (STEM) for users of spatio-temporal transportation resources such as electric vehicle charging stations or parking spaces. STEM exploits the gap between optimum and equilibrium in game theory in order to improve the position of users in competing for such resources, as well as improve social welfare. It does so via a proposed payment scheme called Guaranteed-Agent-Gain (GAG). In this scheme users pay STEM, but if STEM refunds its profit to the users, then the scheme amounts to peer-to-peer transactions. We prove that in many cases GAG does not need to be subsidized in order to deliver its gains to travelers and society. We show that GAG raises the issue of user truthfulness, in the sense that users can gain from being untruthful about their private information, such as their current location. Thus we also analyze the application of Vickrey-Clarke-Groves (VCG) mechanisms studied in economics to the problem of location truthfulness in STEM. We show that these mechanisms can indeed induce location truthfulness, but at the cost of reduced revenue.
