- Use of the contingent valuation method is controversial among economists because it is based on hypothetical rather than real choices. Previous experiments have suggested that the commonly used dichotomous choice contingent valuation method leads to hypothetical bias, i.e., overestimates the real willingness to pay. We carried out an experiment to compare the dichotomous choice contingent valuation method with real purchase decisions for a consumer good. We confirm previous findings that hypothetical yes responses overestimate real purchase decisions, but we cannot reject the null hypothesis that definitely sure yes responses correspond to real purchase decisions.

- We compare hypothetical and real payments in a Vickrey auction. The use of hypothetical payments overestimates the real willingness to pay. The results cast doubt on the validity of hypothetical willingness to pay questions for the typical respondent.

Calibrating hypothetical willingness to pay responses

- Experimental data comparing hypothetical and real dichotomous choice responses for two different goods were used to estimate a statistical bias function to calibrate the hypothetical yes responses. The probability that a hypothetical yes response would be a real yes response was estimated as a function of - the individual's self-assessed certainty of the hypothetical yes response (assessed on a 0-10 scale) and a variable representing the price level. Without calibration the hypothetical yes responses significantly exceeded the proportion of real yes responses, but after calibration the null hypothesis of no difference between hypothetical and real responses could not be rejected in any of the experiments.

Preference Measurement in Health
- 2014
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Measurements of individual benefits of different health and medical interventions are fundamental for prioritizing among different alternative uses of resources in the healthcare sector. While psychometric measures do not necessarily provide information sufficient for assigning relative values to different health states, preference-based approaches produce measures that allow comparisons of such values. In this volume of the series of Advances in Health Economics and Health Services Research, entitled Preference Measurement in Health, the papers cover altruism within families, differences in risk attitudes, and estimation of health benefits of food safety. Specific topics include efficiency and altruism, comparison of mother and daughter values of HPV vaccination for daughters, differences in risk attitudes between women and men, how context matters in valuing food safety programs, and valuation of health risks associated with pesticide use.
