Obviously strategyproof (OSP) mechanisms maintain the incentive compatibility
of agents that are not fully rational. They have been object of a number of
studies since their recent definition...A research agenda, initiated in
[Ferraioli&Ventre, AAAI 2017], is to find a small (possibly, the smallest) set
of conditions allowing to implement an OSP mechanism. To this aim, we define a
model of probabilistic verification wherein agents are caught misbehaving with
a certain probability, and show how OSP mechanisms can implement every social
choice function at the cost of either imposing very large fines for lies or
verifying a linear number of agents.(read more)
