Impacts of demand and supply-side interventions on South Korea’s housing markets: a dynamic housing-CGE analysis

Abstract

<p>This paper examines the impacts of housing market policies in Korea by developing a dynamic computable general equilibrium model integrating regional housing markets and multiregional mobility. We compare simulation outcomes of demand- and/or supply-side approaches in housing market interventions and address how these various policy instruments affect housing prices, demand, and household welfare. Policy simulation results suggest that supply-based interventions would be more effective than housing tax policies for cooling down overheated housing markets without decreasing consumer welfare. Tax-based demand-side approaches result in a 1.8–2.2% housing price drop and a 1.1–1.2% welfare decline annually between 2021 and 2024. In the supply-side policy, investing in housing construction leads to 3.4–4.1% lower housing prices and 1.5–1.8% enhanced welfare.<br></p>
