Public and private roles in road infrastructure: an exploration of market failure, public instruments and government failure [PDF]
Starting with a 'greenfield' situation, we discuss reasons for market failure in road infrastructure provision. We show why it may not be optimal from a welfare perspective to leave road provision fully to the market and government intervention in this ...
