Jappelli, Tullio, Julliard, Christian and Pagano, Marco (2001) La diversificazione del portafoglio delle famiglie italiane. In: Beltratti, A., (ed.) XIX Rapporto sul Risparmio e sui Risparmiatori in Italia. BNL / Centro Einaudi, Italy, pp. 91-121.
This paper performs an efficiency analysis of households portfolios based on the comparison of observed portfolios with the mean-variance frontier of assets returns. Data on household portfolios are drawn from the 2001 Centro Einaudi survey, a representative sample of the Italian population with at least a bank account. We find that most households' portfolios are extremely close to the efficient frontier once we explicitly take into account no short-selling constraints, while the null hypothesis of efficiency is rejected for all portfolios if we do not consider these constraints.
