Public preferences for establishing nephrology facilities in Greenland: estimating willingness-to-pay using a discrete choice experiment
At present there are no nephrology facilities in Greenl and . Greenl and ic patients with renal failure needing dialysis thus have to travel to Denmark to obtain treatment . For patients in haemodialysis this necessitates a permanent residence in Denmark . Our study was aim ed at examining Greenl and ers ’ preferences for  establishing nephrology facilities in Greenl and at Queen Ingrid ’s Hospital in Nuuk , and to estimate the associated change in welfare . Preferences were elicited using a discrete choice experiment ( DCE ) . A r and om sample of 500 individuals of the general population was sent a postal question naire in which they were asked to consider the trade-offs of establishing nephrology facilities in Greenl and as opposed to the current situation . This involved trading off the benefits of having such facilities in their home country against the costs of the intervention . Besides including a payment attribute described in terms of incremental tax payment , the DCE included two interventions attributes related to ( 1 ) the organisation of labour , and ( 2 ) the physical setting s of the patients . Respondents succeeded in answering the DCE despite cultural and linguistic disparity . We found that all the included attributes had a significant effect on respondents ’ choices , and that respondents ’ answers to the DCE were in keeping with their values as stated in the question naire . DCE data was analyzed using a r and om parameter logit model reparametrized in willingness-to-pay space . The results showed that establishing facilities in Greenl and were preferred to the current treatment in Denmark . The welfare estimate from the DCE , at DKK 18.74 million , exceeds the estimated annual costs of establishing treatment facilities for patients with chronic renal failure . Given the estimated confidence interval this result seems robust . Establishing facilities in Greenl and therefore would appear to be welfare-improving , deriving positive net benefits . Despite the relatively narrow policy focus , we believe that our findings provide some insight into individuals ’ preferences for de central ization of public services and on citizens ’ views of ‘ self-governance ’ that go beyond the case of Greenl and . More generally , this paper illustrates how DCE can be applied successfully to developing countries with culturally , demographically , and geographically distinct features
