| Research Abstract |
To determine the influence of income reduction on utility scores, we obtained utility scores of eight health states with three instruction types. Respondents were randomly sampled from the on-line panel and asked to evaluate one of 24 patterns by both standard gamble (SG) and time trade-off (TTO) methods.
An assumed income reduction clearly influenced utility scores; however, compensation for lost income failed to sufficiently improve utility scores. In our view, the effect of income on utility scores does not only reflect wage loss. Our results suggest that the impact of double counting is negligible.
