This paper introduces and discusses some of the statistical properties of a time-varying parameter stochastic volatility (SV) in mean model. We derive the autocovariance function of an observed series, under the assumption that the conditional variance follows a flexible parameterization, which...

The purpose of this article is twofold. Firstly, by applying the event study methodology, it provides detailed and updated evidence on the value generating effect of different modes of foreign direct investment (FDI) entry. Secondly, this is the first paper to empirically evaluate the impact of...

This article discusses the application of the EM algorithm to factor models with dynamic heteroscedasticity in the common factors. It demonstrates that the EM algorithm reduces the computational burden so much that researchers can estimate such models with many series. Two empirical applications...
