In recent years, banks have become increasingly aware of the credit risk borne in lending in the interbank market and they select their counterparties accordingly. They may also fear that if they come across a bad borrower, rescue plans will be skewed towards domestic creditors; moreover,...

We propose a portfolio selection model based on a class of monotone preferences that coincide with mean-variance preferences on their domain of monotonicity, but differ where mean-variance preferences fail to be monotone and are therefore not economically meaningful. The functional associated to...

Data from the Italian Survey of Households Income and Wealth (SHIW) are used to study portfolio allocations change in response to fluctuations in wealth. In particular I test for the prediction of models with habit formation that changes in liquid wealth will affect households' risk aversion and...

The investment of the ECB reserves in US dollars and yen involves an annual performance assessment of portfolio managers, located in the Eurosystem�s national central banks. Employing new data on individual portfolios during 2002-2009, we study this peculiar tournament and show the...

This paper proposes a test for the cost-based explanation of non-participation, by estimating a lower bound to the forgone gains of incomplete portfolios; these are in turn a lower bound to the costs that could rationalize non-participation in financial markets: high bounds would imply...

This paper builds a unifying framework based on the theory of intertemporal consumption choices that brings together the limited participation-based explanation of the C-CAPM poor empirical performance and the transaction costs-based explanation of incomplete portfolios. Using the implications...

A striking feature of financial market behaviour in recent years has been the low level of price volatility over a wide range of financial assets and markets. The issue has attracted the attention of central bankers and financial regulators due to the potential implications for financial...

The data collected by the IMF in the Coordinated Portfolio Investment Survey (CPIS) provide a unique source for foreign portfolio asset holdings, with details on the breakdown by instrument and counterpart country. In the presence of sizeable cross-border positions in mutual funds, which are...

Using a clustering procedure, we classify Italian funds ex-post on the basis of the composition of their portfolios and find that the optimal number of clusters is equal to 4. The four groups which result from the statistical classification closely match the 4-level aggregation of the 20 ex-ante...

We solve two robust portfolio selection problems, where a maxmin criterion is adopted to deal with parameter uncertainty. The two models, which yield closed formulae for the optimal allocation, lend themselves to be thoroughly analyzed both from a geometric and a game-theoretic point of view.
