Habit Formation Hypothesis in Repayment

RCTReview

Lenders frequently worry that providing a grace period prevents borrowers from developing regular repayment habits, thereby increasing default rates through behavioral complacency rather than business risk.

Picture this

Think of brushing your teeth every morning. Doing it every single day without interruption makes it an automatic habit, whereas taking a two-month break might make it harder to get back into the routine once you have to start again.

What the evidence says

Grace period and regular contract clients were equally likely to make their first payment on time (95.3% control vs 97.7% treatment) and equally likely to repay at least 50% of the loan balance (98.8% control vs 97.2% treatment), disproving habit formation disruption as the driver of higher overall default.

Who was studied
N = 845 low-income female microfinance borrowers in Kolkata, India.
How
Field RCT analyzing installment compliance dates, administrative payment logs, and initial meeting attendance across grace period and regular loan groups.

What to do

Maintain strict post-grace period installment enforcement to preserve repayment discipline once initial payments commence.

From the source

"An alternative explanation for the default result is habit formation: a grace period may prevent clients from acquiring regular payment habits... In contrast, columns 5-7 of Table 3 indicate that grace period and regular clients were equally likely to make their first payment and just as likely to repay at least half of the loan."
