Lending Without Access to Collateral: A Theory of Microloan Borrowing Rates
We develop a model of lending and borrowing in markets where the lender has no access to physical collateral and where the borrower is heavily capital constrained. Our model of micro loans, which incorporates a) the absence of access to physical collateral, b) peer monitoring, c) threat of punishment upon default, and d) costly monitoring by lenders is used to determine the equilibrium borrowing rates. Monitoring by lenders is shown to be critical for an equilibrium to exist in our model if the maturity of the loan is too long.
