| Abstract: | This research studies the welfare consequences of product differentiation on congested networks with the help of consistent agent-based techniques. The economic analysis concentrates on the source, evolution, measurement, and effect of product differentiation with heterogeneous users on a mixed ownership network. Path differentiation and space differentiation are defined and measured for a base scenario and several variants. The implications favour a fixed-rate road pricing policy compared to full pricing freedom on toll roads. It is also shown that the effect of production differentiation on welfare can also be negative depending on the level of user heterogeneity. |
