摘要：In this study, we revisit the issue as to the presence of Rational Bubbles in the Korea stock market during the May 1996 to November 2007 period using three cointegration tests, namely JJ (Johansen and Juselius, 1990), KSS (Kapetanois et al., 2006) and BN (Bierens, 1997, 2004) approaches. The results from the conventional JJ test support the existence of rational bubbles, whereas those from both nonlinear test of KSS and nonparametric test of BN attest to the absence of rational bubbles in the Korea stock market.
