Scope Insensitivity in Child's Health Risk Reduction: A Comparison of Damage Schedule and Choice Experiment Methods

The focus of this study is to explore the issue of scope insensitivity concerning two different elicitation formats with regard to differences in preferences distributions. For this purpose, we apply choice experiment (CE) and damage schedule (DM) methods to elicit preferences for different child’s health risk reductions in school in Thailand. The data comes from 1,116 parents who have at least one child attending school from prepared kindergarten to grade 9. Empirical evidences first suggest that these two methods provide the same preferences of respondents on the most preferred and the least preferred of risk reduction issues. However, scope insensitivity occurs for some risk reductions issues elicited by CE. Namely, willingness to pay of higher level of risk reduction and those of lower level of risk reduction in the same issue are statistically indifferent. On the other hand, there is no occurrence of scope insensitivity in all risk reduction issues obtained by DM. This pattern is still unchanged even when the sample is separately analyzed by socio-economic factors such as education and income.
