Do capability and functioning differ? A study of U.K. survey responses
研究基于英国943人样本，发现约三分之一的人在至少一个生活领域报告了能力与功能的差异，且差异与教育程度和健康状况相关，提示评估空间的选择可能影响公共支出优先级的设定。
A core feature of the capability approach is that a person's capabilities (what they are able to do and be in their life) can differ from their functionings (what they actually do and are in their life). However, the degree to which capability and functioning differ in practice is unclear. This paper investigates this issue, focusing on capability and functioning differences (CFD) across different aspects of life and different individuals. In the study, the ICECAP-A capability questionnaire was modified to measure both functionings and capabilities and was completed by U.K.-based convenience sample of 943 people. Around one third of people reported CFD in at least one area of their life, most commonly in terms of their "achievement." People were more likely to report CFD when they had a degree-level education and when they had impaired health. An additional finding was that capability varied more with education whereas functioning varied more with health status. This finding needs further examination, but it suggests that the choice of evaluative space may influence how priorities are set for public spending.
