This paper considers observation driven models with conditional mean and variance dynamics for non-negative valued time series. The motivation is to relax the restriction imposed on the higher order moment dynamics in standard multiplicative error models driven only by the conditional mean...

In this paper we investigate three empirical aspects of emerging stock markets. First, we use the endogenous structural break techniques of Bai (1996) and Bai and Perron (1998) to identify stock market opening dates in 16 different emerging market countries. The results indicate that there is...
