We analyze the role of debt in persuading an entrepreneur to pay out c
ash flows, rather than to divert them. In the first part of the paper
we study the optimal debt contract-specifically, the trade-off between
the size of the loan and the repayment-under the assumption that some
debt contract is optimal. In the second part we consider a more gener
al class of(nondebt) contracts, and derive sufficient conditions for d
ebt to be optimal among these.
