This study analyzes spillover effect which occurred in emerging and advanced economies, resulting from the US financial crisis and Greece sovereign debt crisis, covering the period of January 2003-December 2011. Using the log likelihood approach, this research employs several univariate models, i.e. MA(1) GARCH (1,1)-M, MA(1) GARCH (1,1) and MA(1) GJR (1,1), with modified lag squared return of the crisis country during the pre-crisis (normal) and crisis periods. Empirical result demonstrate that : First, volatility is time varying, Second found an increase spillover effect in the crises period compare to the normal period. The magnitude of spillover is influenced at least by the degree of market openness between the crisis country and other countries. Third MA(1) GJR (1,1) is outperformed univariate model that described the data in this study compare to the others. Fourth there is not significant correlation between conditional volatility and excess return in the most country. Last, volatility is asymmetrical, and developing country is more sensitive to the negative shock in the America and Greek crises period.
