부동산가격지수와 리츠가격지수 간의 관계 - 본질가치와 일시적 가치를 중심으로 -

This paper empirically examines the link between unsecuritized real estate market and REIT market in the U.S.. In contrast to previous papers, which have studied on observed price only, observed real estate price is separated into fundamental value and transitory value, in this study. This study employs the unobserved component model to estimate fundamental value and transitory value. Federal Housing Finance Agency Housing Price Index(FHFA Index) is used for unsecuritized real estate market, and FTSE NAREIT Equity Residential Index(NAREIT Index) is used for REIT market. In the case of observed FHFA Index, the Granger causality tests show that there is one-way Granger causality from the observed FHFA Index to NAREIT Index. In the case of fundamental value, there is also one-way Granger causality from the fundamental value of FHFA Index to NAREIT Index. In the case of transitory value, there is unidirectional Granger causality from the transitory value of FHFA Index to NAREIT Index. In short, these results suggest that FHFA Index is closely related with NAREIT Index and REIT prices reflect real estate market fundamentals. FHFA Index could be used to help predict NAREIT Index. The relationship between REIT price and real estate price may be crucial implication regarding portfolio formation strategy and price prediction.
