    Question Description

    Discussion Question:

    Credit assessment helps banks in assessing and evaluating their potential borrowers in order to ascertain whether a potential borrower will be able to discharge his loan obligations as per contractual agreement with bank. There are many different credit assessment models commonly used in the market for standardized evaluation of credit assessment data, including heuristic models, empirical statistical models, and causal models. In practice, hybrid models are also used which combine two or three above mentioned models for credit assessment.

    Being a student of Credit and Risk Management (FIN725), you are required to give your opinion that whether heuristic or empirical statistical models are more suitable for the credit assessment of potential borrowers? Elaborate your answer by writing various features of heuristic and empirical statistical models.

    Important Instructions:

    1. Your discussion must be based on logical facts.

    2. The GDB will remain open for 06 working days.

    3. Do not copy or exchange your answer with other students. Two identical / copied comments will be marked Zero (0) and may damage your grade in the course.

    4. Obnoxious or ignoble answer should be strictly avoided.

    5. Questions / queries related to the content of the GDB, which may be posted by the students on MDB or via e-mail, will not be replied till the due date of GDB is over.

    NOTE: Copied Comments from any source will be marked as ZERO.

    Heuristics are the strategies derived from previous experiences with similar problems. These strategies depend on using readily accessible, though loosely applicable, information to control problem solving in human beings, machines and abstract issues.[3][4]

    The most fundamental heuristic is trial and error, which can be used in everything from matching nuts and bolts to finding the values of variables in algebra problems. In mathematics, some common heuristics involve the use of visual representations, additional assumptions, forward/backward reasoning and simplification.[5] Here are a few commonly used heuristics from George Pólya’s 1945 book, How to Solve It:[6]

        If you are having difficulty understanding a problem, try drawing a picture.
        If you can't find a solution, try assuming that you have a solution and seeing what you can derive from that ("working backward").
        If the problem is abstract, try examining a concrete example.
        Try solving a more general problem first (the "inventor's paradox": the more ambitious plan may have more chances of success).

    features of heuristic and empirical statistical models

    Much research has highlighted incoherent implications of judgmental heuristics, yet other findings have demonstrated high correspondence between predictions and outcomes. At the same time, judgment has been well modeled in the form of as if linear models. Accepting the probabilistic nature of the environment, the authors use statistical tools to model how the performance of heuristic rules varies as a function of environmental characteristics. They further characterize the human use of linear models by exploring effects of different levels of cognitive ability. They illustrate with both theoretical analyses and simulations. Results are linked to the empirical literature by a meta-analysis of lens model studies. Using the same tasks, the authors estimate the performance of both heuristics and humans where the latter are assumed to use linear models. Their results emphasize that judgmental accuracy depends on matching characteristics of rules and environments and highlight the trade-off between using linear models and heuristics. Whereas the former can be cognitively demanding, the latter are simple to implement. However, heuristics require knowledge to indicate when they should be used.
