Answer: Probability of 30-day delinquency
An **incentive function** measures the borrower's economic motivation to prepay, especially through refinancing. It typically includes variables such as: - the **present value of payment savings** from refinancing, - the **rate differential** between the existing mortgage and current market rates, - the **monthly payment reduction** obtained by refinancing. The **probability of 30-day delinquency** is not an incentive for voluntary prepayment; it is related to credit performance and default risk, not refinance motivation.
