초등학생의 시간선호율과 지속가능미래 인식의 관계 ; Elementary students' Rate of Time preference and Perception of sustainable future

학위논문 (석사) -- 서울대학교 대학원 : 사범대학 협동과정 환경교육전공, 2021. 2. 홍종호. ; Many people wish to receive the utility at present rather than in the future. This tendency can be quantified to a numeric value which is called the rate of time preference. A low rate of time preference would indicate that someone is future-oriented. However, scholars have various points of view on which rate should be socially appropriate. Because people who have a high rate can underestimate future benefits, some scholars consider it as a concept that discriminates against future generations. Under these circumstances, studies are being conducted to estimate time preference directly from people. However, there is a lack of research related to time preference or perception on sustainable development(SD), for elementary students who can be considered as a part of the future generation. Therefore, this study estimates the rate of time preference among elementary school students. In addition, this study also attempts to find environmental educational implications by exploring which attitudes, perceptions and practical intentions on SD are related to the rate of time preference. A discrete choice model was constructed to estimate the rate of time preference for saving lives and statistical analysis was performed using the Logit model. The choices are to save lives either at present or in the future from the environmental pollution. A survey was targeted towards students in the sixth grade of elementary schools within the metropolitan area of Korea and 301 samples were used for the model construction. As a result of the model estimation, it was estimated that students consider saving 100 people at present equivalent to saving approximately 464 people in the future. Based on this, the students' rate of time preference for saving lives was estimated to be approximately 6% (0.0626). This is lower than the adults' rate of time preference. Therefore, it can be deduced that students make more future-oriented choices than adults. In terms of attitudes on SD, it ...
