Notes on Bonds: Illiquidity Feedback During the Financial Crisis
研究了金融危机期间国债的极端流动性折价，发现折价通过反馈循环放大，流动性差的债券流向长期投资者，同时流动性提供者提高价格，加剧了交易成本。
We trace the evolution of extreme illiquidity discounts among Treasury securities during the financial crisis, when bond prices fell more than 6% below more liquid but otherwise identical notes. Using high-resolution data on market quality and trader identities and characteristics, we find that the discounts amplify through feedback loops, where cheaper, less-liquid securities flow to longer-horizon investors, thereby increasing their illiquidity and thus their appeal to these investors. The effect of the widened liquidity gap on transactions costs is further amplified by a surge in the price liquidity providers charge for access to their balance sheets in the crisis.
