IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this paper we propose a model to evaluate the performance of a Constant Proportion Debt Obligation (CPDO) and assess its rating. We model credit spread evolution in a HJM framework and default events for CPDO are generated by using a reduced form approach. Implementing a numerical algprithm that simulates the strategy of a CPDO, we obtain a rating for CPDO by using Monte Carlo simulations. We find a rating inferior to the one assigned by rating agencies. using our model for credit spread dynamics, the revealed default probability for CPDO could have been predicted.
