Title Optimizing open-ended questions in online questionnaires for measuring price perception and willingness to pay
Year 2006
Access date 21.09.2006
Abstract Open methods for the measurement of willingness to pay, like van Westendorp method, represent a sensible replenishment of the method portfolio. They avoid some of the systematic effects and artefacts other methods are threatened by. While open question formats usually are unproblematic used in telephone and personal interviews, conducting online-surveys open questions can lead to higher drop-out or click-through rates. Conduction pricing studies intended to discover statistically small effects in order to determine optimal pricing, the problems associated with open questions are especially disadvantageous. For this kind of research rather large sample sizes are necessary for which the number of cases can be highly affected by drop-out and click-through effects. To this moment there does neither exist a quantification of these effects necessary to determine accurate sample sizes, nor do we know about the premises and effects that can be influenced to reduce drop-out and click through effects. With this background we conducted a survey in an Online-Access-Panel. Different design aspects of the entry forms (size, position) and the kind of entry (forced, unforced) were systematically varied and their effects on drop-out and click-through effects assessed. In addition, several subjective measures (e.g. the felt difficulty of the task) were included for statistical control. Taken the results, best-practice recommendations for the conduction of online-pricing surveys will be derived and their possibility of implementation will be illustrated.
