Company bankruptcy prediction models and their comparison

Topic: Company bankruptcy prediction models and their comparison

I have to add that I would need a short empirical study with a sample of 20 companies (listed comps that went bankrupt, Data Stream Navigator-Worldscope TH7/Reuters) and its company´s data of a time frame of 1-5 years.

Models include Merton-Model, Z-Score, Moody´s KMV (based on Merton), Neuro-science models (if possible, I did not find anything on it).

Research questions: 1. How are bankruptcy prediction models categorized? On which factors do they rely on? Can economic data connected to the models? 2. Can bankruptcy prediction models predict exactly company´s bankcuptcy? 3. Which bankruptcy prediction models shall be used in Credit management?
