주택시장과 거시경제의 관계에 관한 실증분석

Abstract

The purpose of this paper is to analyze the relationship between the housing market and the macroeconomy using macroeconomic variables, and housing price variables of South Korea from the first quarter of 1991 to the fourth quarter of 2021. In consideration of the macroeconomic transmission mechanism of housing price fluctuations, I built a VAR model with variables such as real GDP, private consumption, housing investment, private credit, policy interest rate, and housing transaction price. In respect of the impulse response, the result of the analysis showed that housing prices rose when real GDP, private consumption, housing investment, and private credit had risen. When housing prices rose, real GDP, prices, private consumption, private credit, and policy interest rates rose. As a result of forecast error variation decomposition, I found that the contribution of changes in housing prices to changes in each variable was not significant, but changes in real GDP and interest rates had a major impact on changes in housing prices. In the historical decomposition I performed, the contribution of policy interest rates to fluctuations in housing prices was also high. In particular, private credit was considerably affected by the rapid increase in housing prices in 2020. Based on the above results, I found that the increase in housing prices had a relatively long-term impact on the credit market but a poor impact on the real economy through increased consumption and housing investment, while I confirmed that the GDP and interest rates had a major effect on changes in housing prices.
