SP-off-RP questions are a recent innovation in choice modelling that solicits information from respondents in a different way than standard stated-preference (SP) experiments. In particular, the alternatives and choice of a respondent in a real-world setting are observed, and the respondent is...

Using data from two Choice Experiment environmental valuation surveys we investigate several different ways of handling respondent uncertainty. In both surveys respondents are asked to state their certainty of choice after each single choice set. We evaluate three different recoding-of-answers...

Car purchase taxes in The Netherlands are among the highest in the EU. The Dutch government plans to gradually replace car purchase and ownership taxes by a national road user charging system (kilometre charge) in the period 2012 to 2016. As a result, new and second hand car prices in the...

When prompting respondents to act on the hypothetical markets that are presented to them in stated preference surveys, it is often observed that a proportion of the sample state a zero demand for the good in question even though their genuine demand is positive. Though the literature comes up...

A brief review of theoretical and empirical literature on the effort expended in making choices is followed by the description of an experiment in which participants were asked to respond to a series of road charging scenarios. Participants were asked to estimate the charges payable, to indicate...

Modeling route choice behavior is problematic, but essential to appraise travelers’ perceptions of route characteristics, to forecast travelers' behavior under hypothetical scenarios, to predict future traffic conditions on transportation networks and to understand travelers' reaction and...

This study uses latent class modeling (LCM) to explore the effects of channel-specific perceptions, along with other variables, on purchase channel intention. Using data on book purchases collected from an Internet-based survey of two university towns in Northern California, we develop a latent...

Motivated by the notion that consumers' use of the internet creates a wealth of data on information search, we put forward the idea that observed information searches may be used for deriving consumer preferences. First, we derive a theoretical model of consumer behaviour under uncertainty and...

Model misspecification is a serious issue since misspecification generally renders statistical inference invalid. However, specification testing of discrete choice models is rarely applied. This paper describes a nonparametric test procedure which uses a combination of smoothed residual plots...
