In this paper we consider several time-varying volatility and/or heavy-tailed models to explain the dynamics of return time series and to fit the volatility smile for exchange-traded options where the underlying is the main �Borsa Italiana� stock index. Given observed prices for the...

Estimates of the real term structure for the euro area implied by French index-linked bonds are obtained by means of a smoothing spline methodology. The real term structure allows computation of the constant-maturity inflation compensation, which is compared with the surveyed inflation...

This paper uses the celebrated no-arbitrage affine Gaussian term structure model applied to index-linked and standard government bonds to derive expected inflation rates and inflation risk premia, in the euro area and in the US. Maximum likelihood estimates show that the model describes the...

The no-arbitrage affine Gaussian term structure model is used to analyse the impact of macroeconomic surprises on the nominal and the real term structure in the euro area and in the United States. We find that nominal rates are affected by surprises in economic growth, the labour market and the...

The information content of stock prices is analysed without imposing strong restrictions on traders' preferences and the distribution of dividends. Noise in the information contained in equilibrium prices arises from endogenous asset supply, which offsets price movements due to informed trading....

We study the one-dimensional Ornstein-Uhlenbeck (OU) processes with marginal law given by the tempered stable and tempered infinitely divisible distributions proposed by Rosinski (2007) and Bianchi et al. (2010b), respectively. In general, the use of non-Gaussian OU processes is impeded by...

In this paper we conduct an empirical analysis of daily log-returns of Italian open-end mutual funds and their respective benchmarks in the period from February 2007 to June 2013. First, we estimate the classical normal-based model on the log-returns of a large set of funds. Then we compare it...

We develop a dynamic multivariate default model for a portfolio of credit-risky assets in which default times are modelled as random variables with possibly different marginal distributions, and L�vy subordinators are used to model the dependence among default times. In particular, we...

In this paper we develop a portfolio optimization strategy based on the extraction of option-implied distributions and the application of robust asset allocation. We compute the option-implied probability density functions of the constituents of the Euro Stoxx 50 Index. To obtain the...

Most of the important models in finance rest on the assumption that randomness is explained through a normal random variable because, in general, the use of alternative models is obstructed by the difficulty of calibrating and simulating them. In this paper, we empirically study models for...
