A New Consensual Approach
Part of the Contributions to Economics book series (CE)
A feature common to all survey approaches suggested in the literature so far is that stimulus and response categories differ: all questionnaire designs either use household income as a stimulus variable and ask for the corresponding level of household welfare or vice versa. As mentioned above, this questionnaire characteristic casts doubts on the reliability of the collected data. We will present a new questionnaire design that overcomes this problem by using household income as the dimension for both, stimulus and response. A typical question reads:
“According to your opinion, which family income level can make a household with one adult and two children achieve the same well-being as a household with one adult only and an income of DM 1,000?”
