摘要: Over recent years there has been renewed interest in cost-benefit analysis (CBA) health care but the 'hypothetical bias' concern (i.e. belief that WTP values overstate real preferences) is a remaining anxiety. This paper reports new empirical data comparing hypothetical and preferences context, using clinical setting of patient self-management (PSM) anticoagulation (warfarin) therapy. The offer considerable support for use CBAs context; bias hypothesis not supported by our data. generalisability these results to other settings needs be explored.
