Larger firms (by sales or employment) have higher leverage. This pattern is explained using a model in which firms produce multiple varieties and borrow with the option to default against their future cash ow. A variety can die with a constant probability, implying that bigger firms (those with...

We propose a theory of optimal firm financing given nested information problems of adverse selection and agency cost. We prove that there exists a unique perfect Bayesian equilibrium with novel features: First, three types of optimal contracts arise endogenously, i.e., equity, transparent debt...

In this article we argue that asymmetric information can explain why seignorage is an inferior choice to debt for governments. We also argue that the Ricardian equivalence for governments is very similar to what the Modigliani-Miller proposition is for corporations. Our model is based on Bolton...

Models based on asymmetric information predict that debt is least sensitive to private information and cannot explain the illiquidity of corporate debt in secondary markets. We analyze security design with moral hazard and offer a new explanation. First, the optimal compensation contract creates...

We study a dynamic agency model where the agent privately observes the firm's cash flows that are subject to persistent shocks. We characterize the policy dynamics and implement the optimal contract by financial securities. Because bad performance distorts investors' beliefs downward, the agent...

In this paper, we adapt a continuous-time agency model to incorporate the loss-aversion preferences of agents. To this end, by distinguishing between the gains in capital and income driven by variations in the agent's continuation payoff, we provide a theoretical model which overcomes the...

We propose a theory of security design in financing entrepreneurial production, positing that the investor can acquire costly information on the entrepreneur's project before making the financing decision. When the entrepreneur has enough bargaining power in security design, the optimal security...

Building on the trade-off between agency costs and monitoring costs, we develop a dynamic theory of optimal capital structure with financial distress and reorganization. Costly monitoring eliminates the agency friction and thus the risk of inefficient liquidation. Our key assumption is that...

The global economy is in the midst of an unprecedented slump caused by the coronavirus pandemic. This systemic risk like no other at a time of record-breaking debt levels, especially among nonfinancial firms across the world, could exacerbate corporate vulnerabilities, deepen macro-financial...

I hypothesize firms in highly innovative industries — those with high risk, yet higher potential return — will be more likely to raise funds through stock markets than firms in mature industries. Using the product life-cycle as a theoretical framework, this is all placed within the context...
