This paper studies the dependence in Mexican and Brazilian financial markets through a method that has proved to obtain better results —along with the characterization of non-linearity and asymptotic dependence— than the use of simple correlation analysis: the copula approach. Using weekly...

“Orthogonal portfolios” methodology applied by Roll (1980), in order to get an orthogonal zero-beta portafolio when we have a nonefficient market index in Mean-Variance approach, is used by MacKinley and Pastor (2000) to obtain a non observed risk factor that considers the information aj?0...
