Willingness to pay for public health care: a comparison of two approaches

When applying willingness-to-pay (WTP) in economic evaluations, there have been strong theoretical arguments for the use of ex ante insurance-based questions, which can be framed either as insurance premiums or taxation contributions. This paper suggests theoretical reasons why respondents may value a programme differently in these two different ex ante approaches, and inquires empirically into the potential existence of such differences. A split-sample interview study was undertaken in Denmark. The proportion of respondents willing to pay is higher in the community version, and the respondents use different reasons for being and not being willing to pay.
