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...

We introduce a two-country no-arbitrage term-structure model to analyse the joint dynamics of bond yields, macroeconomic variables, and the exchange rate. The model allows to understand how exogenous shocks to the exchange rate affect the yield curves, how bond yields co-move in different...

We study the dynamics of risk premiums on the German bond market, employing no-arbitrage term-structure models with both observable and unobservable state variables, recently popularized by Ang and Piazzesi (2003). We conduct a specification analisys based on a new canonical representation for...

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.

When the riskiness of an asset increases, then, arguably, some risk-averse agents that were previously willing to hold on to the asset are no longer willing to do so. Aumann and Serrano (2008) have recently proposed an index of riskiness that helps to make this intuition rigorous. We use their...

This paper proposes a Bayesian regression model with time-varying coefficients (TVC) that makes it possible to estimate jointly the degree of instability and the time-path of regression coefficients. Thanks to its computational tractability, the model proves suitable to perform the first (to our...

Since the outbreak of the financial crisis in 2007, the level and volatility of Euribor � OIS differentials have increased significantly. According to the extant literature, this variability is mainly explained by credit and liquidity risk premia. I provide evidence that part of the...

This paper examines the recent behavior of sovereign interest rates in the euro area, focusing on the 10 year yield spreads relative to Germany for Italy and other euro area countries. Both previous analyses and the new evidence presented in the paper suggest that, in recent months, for several...

The ratio between current earnings per share and share price (the EP ratio) is widely considered to be an effective gauge of under/over-valuation of a corporation�s stock. Arguably, a more reliable indicator (the cyclically-adjusted EP ratio) can be obtained by replacing current earnings...

We analyse the wide array of rescue programmes adopted in several countries, following Lehman Brothers� default in September 2008, in order to support banks and other financial institutions. We first provide an overview of the programmes, comparing their characteristics, magnitudes and...
