Review of Financial Studies, forthcoming


Recent empirical studies show that innovative firms heavily rely on debt financing. Debt overhang implies that debt hampers innovation by incumbents. A second effect of debt is that it stimulates innovation by entrants. Using a Schumpeterian growth model with endogenous R&D and financing choices, we demonstrate that this second effect always dominates, so that debt fosters innovation and growth at the aggregate level. Our analysis suggests that the relation between debt and investment is more complex than previously acknowledged and highlights potential limitations of empirical work that focuses solely on incumbents when measuring the effects of debt on investment.

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 remaining life of their capital, generating maturity cycles. These firm-level financing cycles drive aggregate leverage and maturity dynamics when capital age is correlated across firms. We provide time series and cross-sectional evidence that strongly supports these independent predictions and highlights the key roles of capital age and asset life in financing cycles.


We examine how product life cycle affects investment and financing by estimating an industry equilibrium model that embeds product portfolio characteristics. In the model, firms trade off higher profitability of newer products versus product introduction costs. Using product-level data, we find that the product dimension is critical in quantitatively explaining cash flow dynamics, corporate policies, and industry structure. We show that product introductions and capital investment are complements and that product dynamics incentivize preserving more debt capacity. Our estimates reveal that product life cycle is more pronounced for firms with smaller and more concentrated product portfolios as well as those with high product variety.


I develop a dynamic capital structure model to examine how the nature of risk affects debt policy. In the model, the firm's fundamental risk, captured by its cash flow process, consists of transitory and persistent parts with markedly different dynamics. The model explains the observed dispersion in the risk-leverage relationship. Firms with similar total volatility adopt distinctive debt policies when the composition of their risk differs and issue less debt when their cash flows are more persistent to preserve debt capacity needed to fund investment. The model also provides rationale why the observable dispersion in cash flow persistence is low, which is at odds with the large degree of heterogeneity in other firm characteristics, as well as why persistence and leverage are weakly related in the data.
