This paper has a twofold objective. First, we develop a new method to assess the monetary valuefor individuals of external effects. The method makes use of an ordinal index of life satisfaction asscored by individual respondents who are subjected in varying intensity to the external effect....

We analyse congestion pricing in a road and rail network with heterogeneous users. On the road there is bottleneck congestion. In the train there is crowding congestion. We separately analyse "proportional heterogeneity" that varies the values of time and schedule delay scalarly in fixed...

We assess the monetary value of the noise damage, caused by aircraft noise nuisance around Amsterdam Airport, as the sum of hedonic house price differentials and a residual cost component. The residual costs are assessed from a survey, including an ordinal life satisfaction scale, on which...

We analyse river sharing games in which a set of agents located along a river shares the available water. Using coalition theory, we find that the potential benefits of water trade may not be sufficient to make all agents in the river cooperate and acknowledge property rights as a prerequisite...
