The course focuses on the state of the art of methodologies and practices of credit risk management in financial institutions, as well as in finance departments of large non-financial corporations. Risk measurement models and management policies are constantly linked in order to provide a comprehensive picture of key methodologies and tools that are currently under implementation in banks, non-financial institutions, and rating agencies. The course capitalizes on large real-world data-bases and statistical software tools such as SPSS, in order to learn how to build, manage and validate risk models; lectures are held in computer room. There are no particular prerequisites of statistics and/or SPSS software for those attending the course; SPSS will be downloaded on students’ lap tops.
