Applied econometrics on multilevel panel data: corporate capital structure and investment models; the role of R&D and innovation on financing; the role of uncertainty; the role of ownership; heterogeneous behaviours and clustering; dynamic models, instrumental variables and the use of the principal components. I also worked on selection bias, problems in measuring tangible and intangible capital stocks, microsimulation models of the corporate
taxation and effects of the institutional characteristics on the financial behaviour of companies.
