We sought to compare the performance of the EQ-5D and SF-6D with regard to the criteria of practicality, convergent validity, and construct validity, the level of agreement between the two measures was also assessed. Responses from 1865 individuals aged 45 years in one general practice were...

In a previous paper, the reliability of willingness-to-pay (WTP) values was found to be an increasing function of the size of WTP expressed. Here, the results of a qualitative exercise conducted alongside this quantitative study are presented. The results of this exercise suggest that higher WTP...

A general population sample of 135 Australian respondents completed one of four contingent valuation surveys that asked them to value health benefits either in the absence of an explicit reference good or in the presence of one of three different forms of reference good. Results suggest that...

A general population sample of 104 Australian respondents completed an interviewer-administered contingent valuation (CV) survey that asked them to value five scenarios representing the same core improvement in health status. These scenarios varied only in the degree of narrative used to...

A key theoretical prediction concerning willingness to pay is that it is positively correlated with benefit size and is assessed by testing the 'sensitivity to scale (scope)'. 'External' (between-sample) sensitivity tests are usually regarded as less powerful than 'internal' (within-subject)...

This paper directly compares the relative sensitivity of time-trade-off (TTO) and willingness-to-pay (WTP) values obtained for various levels of change in health status. This was achieved by administering a TTO and WTP survey to a population of 50 subjects, assessing their valuation of various...

In a recent issue of Health Economics Letters, Whynes et al. report an observation not previously reported in the willingness-to-pay (WTP) literature; that when people are asked to provide an estimate using payment scales they tend to disproportionately select prominent values (that is, 1, 2, 5,...

Little is known about the possible impact of an influenza pandemic on a nation's economy. We applied the UK macroeconomic model 'COMPACT' to epidemiological data on previous UK influenza pandemics, and extrapolated a sensitivity analysis to cover more extreme disease scenarios. Analysis suggests...
