This paper explores the criterion validity of stated preference methods through experimental referenda that capture key characteristics of a stated preference survey for a proposed environmental program. In particular, we investigate whether advisory referenda, where participant votes have either known or unknown weight in the policy decision, can elicit values comparable to that of a standard,...

Knowledge of customer valuation of flight characteristics is important for carriers to decide on service and price levels. It may also be important for regulators to have some knowledge of customer valuation of flight characteristics, as this customer valuation determines to what extent individual flights are substitutes. Furthermore, valuation of characteristics may play a role in infrastructu...

In this study we develop and test an econometric model for combining choice and preference ratings data collected from the same set of individuals. Choice data are modeled using a multinomial logit framework, while preference data are modeled using an ordered response equation. Individual heterogeneity is allowed for via random coefficients providing a link between the choice and ratings data. ...

Decisions about preservation, protection, or development of environmental “commodities” like ground water, atmospheric visibility, open space, wildlife, wetlands, and forests are often made without good information about the value of preservation relative to the cost. Clearly, the economic cost of preservation is often substantial. The cost of preserving wildlife habitat, for example, often tot...

Mode choice modelling is commonly done to estimate the patronage demand of the various available transport modes. Since the late 1990’s in South Africa, Stated Preference (SP) surveys and occasionally Revealed Preference (RP) surveys have been used to estimate the representative trip utility attributes and their associated weightings. The transit utility attributes and weightings are also used ...

6 Monte Carlo experiments are used to study the unbiasedness of several common random utility mod7 els for a proposed adaptive stated preference survey. This survey is used to study the influence of the 8 knowledge of existing mode shares on travelers mode choice. Furthermore, the survey is applied to a 9 sample of subjects selected from the University of Minnesota. The results indicate that th...
