A Liquidity-based Model of Security Design
研究发行人如何设计并出售以特定资产为支持的证券，权衡保留现金流带来的成本与包含现金流导致的流动性成本，并刻画最优证券设计及标准债务的最优条件。
We consider the problem of the design and sale of a security backed by specified assets. Given access to higher-return investments, the issuer has an incentive to raise capital by securitizing part of these assets. At the time the security is issued, the issuer's or underwriter's private information regarding the payoff of the security may cause illiquidity, in the form of a downward-sloping demand curve for the security. The severity of this illiquidity depends upon the sensitivity of the value of the issued security to the issuer's private information. Thus, the security-design problem involves a tradeoff between the retention cost of holding cash flows not included in the security design, and the liquidity cost of including the cash flows and making the security design more sensitive to the issuer's private information. We characterize the optimal security design in several cases. We also demonstrate circumstances under which standard debt is optimal and show that the riskiness of the debt is increasing in the issuer's retention costs for assets.
