Stochastic mortality, i.e. modelling death arrival via a jump process with stochastic intensity, is gaining an increasing reputation as a way to represent mortality risk. This paper is a first attempt to model the mortality risk of couples of individuals, according to the stochastic intensity...

The most common approach for default dependence modelling is at present copula functions. Within this framework, the paper examines factor copulas, which are the industry standard, together with their latest development, namely the incorporation of sudden jumps to default instead of a pure...

In this paper, we address the mortality risk of individuals and adopt parsimonious time- homogeneous a±ne processes for their mortality intensities. We calibrate the models to different generations in the UK population and investigate their empirical appropriateness. We find that, in spite of...

In a recently reprinted paper Borch wonders whether an increase in loadings, together with a consequent increase in deductibles, may start a vicoius circle, ad infinitum. This paper rules out the possibility of a vicious circle, in a model à la Borch. First of all, in his setting, increases in...

The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

This paper provides the static, swap-based hedge for an annuity, and compares it with the dynamic, delta-based hedge, achieved using longevity bonds. We assume that the longevity intensity is distributed according to a CIR-type process and provide closed-form derivatives prices and hedges, also...

We analyze theoretically banks’ choice of organizational structures in branches or subsidiaries in the presence of government bailouts, default costs and - possibly - economies of scale as sources of financial synergies. We compare with stand-alone banks. Subsidiary and branch structures...
