How much of a loan should a lender dynamically retain and how does retention affect loan performance? We address these questions in a dynamic agency model in which a lender originates loans that it can sell to investors. The lender reduces default risk through screening at origination and...

Capital ages and must eventually be replaced. We propose a theory of financing in which firms finance new capital with debt and optimally deleverage to free up debt capacity as their capital ages, thereby generating debt cycles. Concurrently, firms shorten the maturity of their debt to match the...
