The implications of Willingness to Pay of Respondents Ignoring Specific Attributes
Published 2005-01-01
Individuals processing the information in a stated choice experiment are typically assumed to evaluate each and every attribute offered within and between alternatives, and to choose their most preferred alternative. ...

Recovering costs through price and service differentiation: Accounting for exogenous information on attribute processing strategies in airline choice
Published 2005-06-01
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 ...

Combining RP and SP data: Biases in using the nested logit ‘trick’ – contrasts with flexible mixed logit incorporating panel and scale effects
Published 2007-09-01
It has become popular practice that joint estimation of choice models that use stated preference (SP) and revealed preference (RP) data requires a way of adjusting for scale to ensure that parameter estimates across data ...

Ordered choices and heterogeneity in attribute processing
Published 2008-07-01
A growing number of empirical studies involve the assessment of influences on a choice amongst ordered discrete alternatives. Ordered logit and probit models are well known, including extensions to accommodate random ...

Heteroscedastic Control for Random Coefficients and Error Components in Mixed Logit
Published 2006-03-01
Developments in simulation methods, and the computational power that is now available, have enabled open-form discrete choice models such as mixed logit to be estimated with relative ease. The random parameter (RP) form ...

Accounting for Exogenous Information on Decision Maker Processing Strategies in Models of Discrete Choice: Attribute Exclusion Strategies in Airline Choice
Published 2005-08-01
In this paper, we examine the impact of individual specific information processing strategies (IPS) on the inclusion/exclusion of attributes on the parameter estimates and behavioural outputs of models of discrete choice. ...

A Latent Class Model for Discrete Choice Analysis: Contrasts with Mixed Logit
Published 2002-09-01
The multinomial logit model (MNL) has for many years provided the fundamental platform for the analysis of discrete choice. The basic model’s several shortcomings, most notably its inherent assumption of independence from ...
