Recent literature has pointed out that information asymmetries may be the reason for the poor performance of structural credit risk models to fit corporate bond data. It is well known in fact that these models lead to a strong understatement of the credit spread terms structure, particularly on...

We propose a model and an estimation technique to distinguish systemic risk and contagion in credit risk. The main idea is to assume, for a set of $d$ obligors, a set of $d$ idiosyncratic shocks and a shock that triggers the default of all them. All shocks are assumed to be linked by a...

We propose a new index for measuring the systemic risk of default of the banking sector, which is based on a homogeneous version of multivariate intensity based models (Cuadras – Augé distribution). We compute the index for 10 European countries, exploiting the information incorporated in the...

We provide a model able to compute a threshold level for the public debt/GDP ratio, such that a country can be rescued by an official lender (e.g. ESM or IMF). The critical level is defined as the maximum level of debt/GDP, such that it is still possible to put the debt/GDP ratio on a...

We discuss the economic model and the econometric properties of the Convolution Autoregressive Process of order 1 (C-AR(1)), with focus on the simplest gaussian case. This is a first order autoregressive process in which the error terms are dependent on the lagged value of the process. We show...

We model the climate change impact on the risk free term structure in a time deformation model with a persistent component in the stochastic clock. In the spirit of the "rare disaster" representation of climate change we specify a "pure" jump model for consumption. Climate change is claimed to...

We provide a structural model of sovereign credit risk, where the risk premium paid by the government is linked to some key economic variables of a country: public debt and deficit, GDP growth. This model is then applied to measure the impact of splitting the public debt into a senior and a...
