In Simple Words
Imagine a city government that pays a small insurance premium to a private bike-share company so it can offer free helmets to riders. The small payment covers the cost of lost helmets, encouraging far more people to ride bikes safely and boosting local economic activity well beyond the original cost of the subsidy.
Research question
Private microfinance institutions cannot sustainably offer grace period loan contracts because market interest rates required to break even under selection and moral hazard are too high or politically unviable, trapping micro-entrepreneurs in low-growth investments.
Participants
N = 845 MFI microfinance borrowers in Kolkata, India (simulated financial model calibrated from experimental profit and default data).
Study Design
Empirical credit market model simulation evaluating government subsidy requirements to offset lender default losses relative to client long-term profit gains.
Results
A targeted public subsidy of Rs 150 per borrower renders microfinance lenders indifferent between classic and grace period contracts at standard 17.5% APR interest rates, generating an estimated annual social return on public capital of 178% based on an average monthly profit gain of Rs 287 per client.
Takeaway
Establish first-loss government loan guarantee pools for microfinance lenders that introduce deferred payment options for business expansion borrowers.
