Corporate Liquidity and Capital Structure

We solve for a firm's optimal cash holding policy within a continuous time, contingent claims framework using dividends, short-term borrowing, and equity issues as controls assuming mean reversion of earnings. Optimal cash is non-monotone in business conditions and increasing in the level of long-term debt. The model matches closely a wide range of empirical benchmarks and predicts cash and leverage dynamics in line with the empirical literature. Firm value is quite insensitive to changes in the level of long-term debt. The model has interesting implications for asset substitution, hedging, and pecking order. Growth opportunities do not greatly affect cash holding policy. The Author 2011. Published by Oxford University Press on behalf of The Society for Financial Studies. All rights reserved.
