Efficient Designs for Alternative Specific Choice Experiments
Published 2005-03-01In the past, research on the construction of efficient designs for stated choice experiments has been limited to unlabeled experiments with generic parameter estimates. In this paper, by deriving the asymptotic (co)variance ...Open AccessWorking Paper -
The implications of respondent attribute processing rules and experimental design on WTP in stated choice experiments
Published 2005-06-01Individual’s process the information in stated choice (SC) experiments in many different ways. In order to accommodate decisions rules that are used in processing information, there is good sense in conditioning the ...Open AccessWorking Paper -
Accounting for Heterogeneity in the Variance of Unobserved Effects in Mixed Logit Models
Published 2005-01-01The growing popularity of mixed logit to obtain estimates of willingness to pay (WTP) has focussed on the distribution of the random parameters and the possibility of estimating deep parameters to account for heterogeneity ...Open AccessWorking Paper -
Road User Charging: The Global Relevance of Recent Developments in the United Kingdom
Published 2005-09-01Charging users of the roads for the costs they impose on the system is not new. Economists have been promoting its virtues for as long as arguments about economic efficiency have been in print. What is different today is ...Open AccessWorking Paper -
Sample optimality in the design of stated choice experiments
Published 2005-06-01Stated choice (SC) experiments represent the dominant data paradigm in the study of behavioral responses of individuals, households as well as other organizations, yet little is known about the sample size requirements for ...Open AccessWorking Paper
