Notes on the Econometrics of Asset Allocation and Risk Measurement
These notes, gathered over several years with the inputs of many colleaugues (Celso Brunetti,Francesco Corielli, Massimo Guidolin, Marco Giacoletti, Andrea Tamoni), are focussed on the main econometric ingredients for portfolio allocation and risk measurement: forecasting the distribution of returns of financial assets. The project is empirical and for each topic EVIEWS, R, and MATLAB programmes have been constructed to practically implement the tools introduced (with MATLAB we shall usethe Econometric Toolbox and codes on the Lesage website and download and install the spatial econometrics toolbox).
