This study contributes to the existing literature by combining the multiple methods to clarify the influence of the macroeconomic factors on the real estate investment trust (REIT) index in three Asian countries. The authors, first, use an autoregressive distributed lag (ARDL) bounds test to find that a long-run equilibrium exists between the REIT index and the interest rate, inflation rate, and stock index for China and Singapore. The authors, then, analyze the long- and short-run elasticity of the macroeconomic variables on the REIT index. Finally, using the Granger non-causality test, the authors demonstrate that a unidirectional relationship, in which inflation-rate shifts cause REIT index changes, exists in Japan and Singapore and that a wealth effect, in which stock index movements cause REIT index changes, exists in Singapore. The findings have economic implications for investors seeking to gain from REITs using macroeconomic factors. Keywords: REITs, macroeconomic factor, ARDL bounds test, ARDL long-run model, error-correction model, Granger non-causality test. JEL Classification: C22, G11, L85, D53, C58, F14
