The decision-making and policy formation context in Iceland has been largely devoid of total economic valuations in cost-benefit assessments. Using an internet survey and applying the double bounded dichotomous choice methodology, this contingent valuation study sets out an estimate of the total economic value pertaining to Heiðmörk, a popular recreational area of urban open space located on the fringes of Reykjavík, Garðabær and Kópavogur. In so doing, this case study advances the practice of using non-market valuation techniques in the country. The welfare estimates provide evidence that Icelanders consider Heiðmörk to possess considerable total economic value, with taxpayers willing to pay a mean lump-sum tax in the range 17,039 to 24,790 ISK per payment to secure its preservation, equating to an estimated total economic value of between 5.87 and 35.47 billion ISK. In the light of possible competitive land management demands among Heiðmörk's three owners and many recreational users in the future, the establishment of these values and their potential use in cost-benefit assessments informs the debate concerning whether the area should be preserved or further developed to satisfy economic objectives. Additionally, a body of experimental evidence is formed suggesting that the increased duration of a fixed payment vehicle is associated with much higher total economic valuations compared to a one-year payment period.
冰岛的决策和政策制定背景在很大程度上缺乏成本效益评估中的全面经济评估。本研究采用在线调查和双边界二分选择法,对位于雷克雅未克、加尔扎拜尔和科帕沃古尔边缘的城市开放空间热门休闲区海德马克的总经济价值进行了评估。通过这种方式,本案例研究推进了在该国使用非市场估值技术的实践。福利估计为冰岛人认为海德马克具有相当大的总经济价值提供了证据,纳税人愿意为确保其保护而支付每笔 17039 至 24790 冰岛克朗的平均一次性税款,这相当于总经济价值估计在 58.7 至 354.7 亿冰岛克朗之间。鉴于海德马克的三个所有者和未来众多休闲使用者之间可能存在竞争性土地管理需求,这些价值的确定及其在成本效益评估中的潜在用途为该地区是否应保留或进一步开发以满足经济目标的辩论提供了信息。此外,形成了一套实验证据,表明与一年付款期相比,固定付款期限的延长与更高的总经济估值相关。
