We present an experiment designed to investigate the presence and nature of ordering effects within repeat-response stated preference (SP) studies. Our experiment takes the form of a large sample, full-factorial, discrete choice SP exercise investigating preferences for tap water quality improvements. Our study simultaneously investigates a variety of different forms of position-dependent and p...

This paper presents an econometric technique for circumventing the lack of individual choice data in a framework of binary choice model by utilizing aggregate choice data. The probability of observing a certain number of individuals making choice A out of the total number of individuals in a group is presented as a sum of probabilities of disjoint events, in which some individuals are picked to...

According to decision making theory, if we know the user’s utility Ui = U(si) of all possible alternatives si, then we can uniquely predict the user’s preferences. In practice, we often only know approximate values Vi ≈ Ui of the user’s utilities. Based on these approximate values, we can only make probabilistic predictions of the user’s preferences. It is empirically known that in many real-li...

Allowing for variations in behaviour across respondents is one of the most fundamental principles in discrete choice modelling, given that the assumption of a purely homogeneous population cannot in general (or ever) be seen to be valid. Two approaches have classically been used to address this problem; the use of deterministic segmentations of the population, and the use of a random continuous...

Abstract This work deals with consumers' preferences about coffee. Firstly, a choice experiment is performed on sample of potential consumers. Following this, sensory test involving the tasting two varieties coffee carried out respondents, after which same supplied to them again. An innovative approach for building heterogeneous designs specifically developed case-study, based approximate desig...

Climate change and uncertain economies challenge small Native communities of the North American Arctic, with their reliance on local fish and wildlife resources. Methodological boundaries of single-discipline analyses limit the contribution of academic research to the real-world questions facing Arctic residents. Oversimplified assumptions and lack of data hamper mainstream economic approaches ...

This paper proposes a rank-based estimator for a location parameter in the binary choice model under a monotonic index and symmetry condition, given an initial Jnconsistent estimator for the slope parameter. The estimator converges at the usual parametric rate. Compared with existing estimators, no nonparametric smoothing is needed here. A small Monte Carlo study illustrates the usefulness of t...

Discrete choice models are employed (as the name suggests) to explain a discrete choice that an individual makes. For example, such a choice might be whether or not to join the labor force, whether or not to buy a car, whether or not to continue on to graduate school, whether or not to accept a job with a consulting …rm, or whether or not to sign up with an internet provider. Later in the cours...

Strategic planning, product design and marketing decisions often require a thorough understandinq of consumers' preferences and choice behaviors. This paper describes the use of the Analytic Hierarchy Process (AHP) for eliciting preferences by questionnaire. Using AHP, consumers can comfortably provide quantitative measures of numerous, diverse and intangible influences on their choices. The pr...

INTRODUCTION The national junior doctor recruitment crisis prompts an appraisal of medical student attitudes to different career pathways. The purpose of this study was to perform a national review of surgical career intentions of Irish final year medical students. METHODS Ethical and institutional approval was obtained at each study location. A questionnaire was designed and distributed to f...
