According to neoclassical economic theory, a stated preference elicitation format comprising a single binary choice between the status quo and one alternative is incentive compatible under certain conditions. Formats typically used in choice experiments comprising a sequence of discrete choice...

Underground telecommunications and low-voltage electricity networks have several advantages over overhead networks including reliability of supply, safety and improved visual amenity. The economic viability of replacing existing overhead networks with new underground networks depends on the...

The entry of low cost airlines has thrown out a challenge to all airlines to find ways of attracting passengers, through a mix of fare discounting, greater frequency, improved flight times and no-frill's levels of on-board service. These competitive strategies have an impact on cost recovery. As...

A key feature of many regulatory reviews is determination of the amount of expenditure that should be reflected in the revenue requirement for a service provider. An increasingly important driver in determining the appropriate level of this expenditure is the desired level of service quality and...

Travel time variability (i.e., random variations in travel time) leads to a travel time distribution for a repeated trip from a fixed origin to destination (e.g., from home to work). To represent travel time variability, a series of possible travel times per alternative (departure time, route or...

Within the discrete choice literature, there is growing recognition that some respondents do not process all attributes when evaluating their choice outcomes. Worryingly, the cost attribute is often among those attributes that are likely to be ignored by respondents. We use probabilistic...

In this paper we extend the independent availability logit and combined latent class mixed logit models to accommodate respondents with different consideration sets due to their cost thresholds and cut-offs. Pertinent features of our model are that it is estimated in WTP-space and that the...

Stated choice surveys are used extensively in the study of choice behaviour across many different areas of research, notably in transport. One of their main characteristics in comparison with most types of revealed preference (RP) surveys is the ability to capture behaviour by the same...

According to neoclassical economic theory, the only stated preferenceelicitation format that can feasibly be employed in field studies to which truthful responsecan be the dominant strategy for all respondents is a single binary choice between thestatus quo and one alternative. In studies where...
