The development of Advanced Traveler Information Systems (ATIS) with en-route navigation systems has opened the door to new traffic regulation policies such as collective route guidance based on social costs, i.e. routes that minimize total travel time. However, a critical element for their efficiency is compliance travelers recommendations. It well established optimum different from user equil...

Cost-benefit analysis is probably the most comprehensive method of economic evaluation available and it can be applied in two ways. The human capital approach means that the value of people's contributions is linked to what they are paid. The approach based on individuals' observed or stated preference means that their personal valuations are placed on an activity by assessing how much money th...

One of the more difficult ethical questions from a public decision-making perspective is whether the estimation of benefits from risk reducing projects should be influenced by factors such as age groups and risk domains. For example, should a project that saves the lives of elderly people be assigned a more different benefit value in cost-benefit analyses than one that saves the same number of ...

In some, but not all, contexts, respondents to stated preference valuation studies state a willingness to pay (WTP) higher than what lab or field experiments indicate is the actual amount they would pay. However, several ex ante survey design strategies and ex post calibration techniques can be used to minimize or eliminate hypothetical bias. This article reviews and presents evidence on the ef...

This paper discusses different design techniques for stated preference surveys in health economic applications. In particular, we focus on different design techniques, i.e. how to combine the attribute levels into alternatives and choice sets, for choice experiments. Design is a vital issue in choice experiments since the combination of alternatives in the choice sets will determine the degree ...

I wish to thank several people for their guidance and assistance. First, I thank V. Kerry Smith, Michael Hanemann, Cathy Kling, Ju-Chin Huang, and Nathan Knust for expanding my understanding and encouraging my exploration. I thank Don Lien and De-Min Wu for their statistical guidance and David Popp for his editorial guidance. I thank Todd Abplanalp and Marian Martinez-Pais for their excellent r...

Stated preference (SP) methods are widely used in travel behaviour research and practice to identify behavioural responses to choice situations which are not revealed in the market, and where the attribute levels offered by existing choices are modified to such an extent that the reliability of revealed preference models as predictors of response is brought into question. This paper reviews rec...

In a static setting, willingness to pay for an environmental improvement is equal to compensating variation. In a dynamic setting, however, willingness to pay may also contain a commitment cost. In this paper we incorporate the dynamic nature of the value formation process into a stated preference study designed to test whether there is an important dynamic component (commitment cost) in stated...
