The paper introduces the appropriate within estimators for the most frequently used three-dimensional fixed effects panel data models. It analyzes the behavior of these estimators in the cases of no self-flow data, unbalanced data, and dynamic autoregressive models. The main results are then...

This paper extends the FIGARCH long-memory volatility model to a multivariate framework. The proposed quasi maximum likelihood estimator for the parameters of the model is analyzed through Monte Carlo simulations and is found to perform satisfactorily. A trivariate specification is applied for...
