Air Pollution and Housing Values in Korea: A Hedonic Analysis with Long-range Transboundary Pollution as an Instrument

We estimate the degree and scope of PM2.5-induced negative price shock in Korea’s local housing markets, taking a two-stage hedonic approach. For the analysis, Korea’s local PM2.5 levels are treated as endogenous and are instrumented with regional air pollutants from China. We find that a unit µg/m3 PM2.5 level increase in a Korean city is associated with a 3.7% decline in local residential property value. Long-range transboundary pollution has significant effects on Korea’s local PM2.5 levels with an elasticity of 0.05. These results enrich the sparse hedonic literature on local air-quality valuation in connection to long-range transboundary pollution in East Asia. The advanced methodological features presented in our two-staged identification strategy with a novel instrument is another contribution of this paper.
