There is growing interest in adopting basic income as a new social protection policy in many countries. South Korea is no exception. There have been heated discussions on the benefits and costs of adopting basic income as a universal income support program among policy makers and academics in South Korea. However, one of the problems in the discourse of basic income discussion in South Korea has been a lack of clear definition of basic income. In this study, we develop a basic income fidelity index (BIFI) that can be applied to basic income programs to show how fully a program fits to the basic income concept. Such an index can be useful in making the terminologies and concepts of basic income clearer. We test feasibility of BIFI by applying it to four different case examples of basic income; Alaska Permanent Fund, UK Child Trust Fund, Switzerland’s Basic Income Plan, and Finland’s Basic Income Experiment. We show BIFI can be a useful tool to differentiate various types of basic income. It can be also used to identify strengths and weaknesses of a basic income scheme.

基本收入保真度指数的探索性研究

在许多国家，人们越来越有兴趣将基本收入作为一项新的社会保护政策。韩国也不例外。韩国的政策制定者和学者对采用基本收入作为普遍收入支持计划的收益和成本进行了激烈的讨论。然而，在韩国，关于基本收入的讨论中的问题之一是缺乏基本收入的明确定义。在本研究中，我们开发了可用于基本收入计划的基本收入保真度指数（BIFI），以显示该计划如何完全适合基本收入概念。这样的指数有助于使基本收入的术语和概念更加明确。我们通过将BIFI应用于四个基本收入案例来测试BIFI的可行性；阿拉斯加常设基金，英国儿童信托基金，瑞士的基本收入计划和芬兰的基本收入实验。我们证明了BIFI可以成为区分各种基本收入的有用工具。它也可以用来确定基本收入计划的优缺点。
