Money for health: the equivalent variation of cardiovascular diseases

Abstract

This paper introduces a new method to calculate the extent to which individuals are willing to trade money for improvements in their health status. An individual welfare function of income (WFI) is applied to calculate the equivalent income variation of health impairments. We believe that this approach avoids various drawbacks of alternative willingness-to-pay methods. The WFI is used to calculate the equivalent variation of cardiovascular diseases. It is found that for a 25 year old male the equivalent variation of a heart disease ranges from 114,000 euro to 380,000 euro depending on the welfare level. This is about 10,000 euro - 30,000 euro for an additional life year. The equivalent variation declines with age and is about the same for men and women. The estimates further vary by discount rate chosen. The estimates of the equivalent variation are generally higher than the money spent on most heart-related medical interventions per QALY. The cost-benefit analysis shows that for most interventions the value of the health benefits exceeds the costs. Heart transplants seem to be too costly and only beneficial if patients are young.

Does happiness adapt? A longitudinal study of disability with implications for economists and judges

“…Like Clark and Oswald (2002), Groot et al (2004), Van Praag and Ferrer-i-Carbonell (2004) and Powdthavee (2008), we can ask the conceptual question: how much extra real income would be required to exactly compensate someone for a change in another of the influences 15 upon well-being (in this particular case, for disability)? 14 However, in a somewhat related spirit, Posner (2000) argues persuasively for a better understanding of the emotions.…”

Happiness economics

“…In the empirical literature, there are various proxy measures for individual health, such as individuals' self-reported disabilities or incapacity to perform daily activities, self-reported chronic illnesses or the number of visits to the doctor or days staying at hospital. Some studies, for example, estimate the importance of different chronic illnesses on self-reported health satisfaction while controlling for individual characteristics such as income, age, and working situation (for example, Ferrer-i-Carbonell and Van Praag 2002; Groot et al 2004). This type of estimations allows identifying the relative importance of the different chronic illnesses from an individual subjective perspective, which in turn may help to assess the benefits of various medical interventions when having a limited budget.…”

“…In health economics it has been used to value illnesses (Ferrer-iCarbonell and Van Praag 2002;Groot et al 2004), hours of provided informal care (Van den Berg and Ferrer-i-Carbonell 2007), and the death of a relative (Oswald and Powdthavee 2008b). This method has also been used to value many other non-market goods, notably noise (Van Praag and Baarsma 2005), climate (Brereton et al 2008;Frijters and Van Praag 1998), family size (Plug and Van Praag 1995), flood disasters (Luechinger and Raschky 2009), air quality or pollution (Welsch 2006;Levinson 2009;Luechinger 2009), and terrorism (Frey et al 2009b).…”

The efficiency of a risk reduction program for debris-flow disasters – a case study of the Songhe community in Taiwan

“…Notably, CEA provides information about whether a given program is more cost-effective than others, but not about whether it contributes to an increase in resident welfare (Groot et al, 2004). Conversely, BCA can assess the shifts in resident welfare.…”
