AB - This study examines the relative price dynamics of apartment prices in Seoul following the January 2023 deregulation of speculative control zone designations across 21 non-Gangnam districts, while considering the Special Bogeumjari Loan as part of the contemporaneous policy-finance environment. Using district-level monthly panel data, the study applies difference-in-differences and event-study models to examine both the average relative change and its dynamic adjustment paths.
The results show that deregulation did not lead to a relative price increase in non-Gangnam areas. Instead, non-Gangnam districts followed a weaker relative price path than Gangnam, with the gap gradually widening over time. The results of pre-trend and placebo tests suggest limitations in interpreting the estimates as the isolated policy effect of deregulation. The findings suggest that Seoul’s post-deregulation housing market should be understood as a differentiated adjustment process shaped by overlapping policy measures, policy-finance conditions, and submarket structure.
