Capital ages and must eventually be replaced. We propose a theory of financing in which firms borrow to finance investment and deleverage as capital ages to have enough financial slack to finance replacement investments. To achieve these dynamics, firms issue debt with a maturity that matches the useful life of assets and a repayment schedule that reflects the need to free up debt capacity as capital ages. In the model, leverage and debt maturity are negatively related to capital age while debt maturity and the length of debt cycles are positively related to asset life. We provide empirical evidence that strongly supports these predictions.

We propose a model of due diligence and analyze its effect on prices, payoffs, and deal completion. In our model, if the seller accepts an offer, the winning bidder (or “acquirer”) can gather information and chooses when to complete the transaction. In equilibrium, the acquirer engages in “too much” due diligence. Our quantitative results suggest that the magnitude of the distortion is economically significant. Nevertheless, allowing for due diligence can improve both total surplus and the seller's payoff compared to a setting without due diligence. We use our framework to explore the timing of due diligence, bidder heterogeneity, and breakup fees.
