Based on a rich dataset of an Azerbaijani microfinance institution, we analyze what a lender can pre-determine from own collected repayment records on clients and how lending conditions are adjusted for the knowledge gains. At the same time, the repayment performances and lending policies between agricultural and non-agricultural clients are differentiated. Our results confirm a positive relationship between previous delays and recidivism, which is even enhanced by the severity of the previous overdue payment. With respect to consequences of previous delay, we find that the borrower faces an increase in loan volume rationing in the subsequent loan. All in all, we state that banks’ internal repayment records can contribute to the customer risk assessment.
