Seoul has faced a housing problem due to a housing supply shortage and a high housing cost burden. Seoul has been supplying public rental housing as one of the policies to cope with housing problems in Seoul since 1985. However, negative perceptions of public rental housing cause the residents in the vicinity of public rental housing to participate in NIMBY against the provisions. This paper approaches educational perspectives of the NIMBY phenomenon against public rental housing. We research the educational effect of the supply of public rental housing by studying how public rental housing provisions affect entrance rates from high school to college. We use panel dataset analysis covering 11 years from 2010 to 2020 for the research. This paper finds that provisions of public rental housing negatively affect the entrance rate. However, we also show that the negative educational effect on the entrance rate from the supply of public rental housing is not constant by studying lagged effect of the provisions.
