Abstract or Description

We study the impact of time-varying macroeconomic conditions on optimal dynamic capital structure and the aggregate dynamics of firms in a cross-section. Our structural-equilibrium framework embeds a contingent-claim corporate financing model within a standard consumption-based asset- pricing model. This enables us to investigate the effect of macroeconomic conditions on asset valuation and optimal corporate policies as well as study the impact of preferences on capital structure. We find that capital structure is pro-cyclical at refinancing dates when firms relever, but counter-cyclical in aggregate dynamics, consistent with empirical evidence. Financially constrained firms follow more pro-cyclical policies. Capital structure is path-dependent. Leverage accounts for most of the macroeconomic risk relevant for predicting defaults. The paper also develops a number of novel empirically testable conjectures on capital structure in a dynamic economy.
