Road pricing with limited information and heterogeneous users: A successful case (original) (raw)

Since strictly optimal (first-best) road pricing policies require information that we will probably never have, it is important to investigate what can be done under more restrictive assumptions as to what information is available. One such case is examined in this paper, where the main restrictive assumptions are that all users have the same choice set and that all alternatives have the same monetary cost. Individuals have utility functions with constant marginal utilities of time and money, but these marginal utilities vary across individuals, and are assumed to be unobservable.
