The aim of this paper is to compare the forecasting performance of competing volatility models, in order to capture the asymmetric effect in the volatility. We focus on examining the relative out-of-sample forecasting ability of the models (SETAR-TGA

The paper analyzes the empirical performance between the Stochastic Volatility (SV) and TAR-GARCH models. SV models are flexible enough to explain excess kurtosis, although the inclusion of TAR in the GARCH model improves the variance asymmetry in th

Predicting sales using cannibalization effects is a current major challenge. Several approaches deal with the estimation of cannibalization of new product launches or promotion effects but how to account for it when predicting future sales is still m
