Paolo is Professor in Financial Econometrics at Imperial College Business School. He has a summa cum laude degree in economic statistics from Roma and holds a PhD in Econometrics from the London School of Economics. He is also teaching at the University of Rome La Sapienza and has previously taught at the London School of Economics and at the University of Cambridge.
Paolo's main research interests are empirical asset pricing, portfolio choice, financial econometrics and econometric theory. His publications include The Annals of Statistics, The Journal of Econometrics, The Journal of Time Series Analysis, The Journal of Empirical Finance, The Journal of Monetary Economics, The Review of Financial Studies and Econometric Theory. His work includes:
1 cross-sectional asset pricing:
- asset pricing with unsystematic risk
- asset pricing and portolio choice with misspecified model
- testing for anomalies
- factor models for conditional asset pricing
- inference on risk premia
2. ECONOMETRIC THEORY
- generalized dynamic factor models
Paolo acts as quantitative consultant in asset and risk management and as instructor of executive courses for various financial institutions.
