An MCDA-based Approach for Creditworthiness Assessment

In this paper we propose a deterministic methodology for creditworthiness evaluation based on the Multi-Criteria Decision Analysis (MCDA) method known as MUlticriteria RAnking MEthod (MURAME). This approach allows to rank the firms according to their credit risk characteristics and to sort them into a prefixed number of homogeneous creditworthiness groups. Moreover, the methodology allows to estimate ex-post proxies of the probabilities of default and of the probabilities of transition. Then, we apply the proposed approach to check its capability to evaluate the creditworthiness in real cases; in particular, we consider the case of an important north eastern Italian bank.
