英文摘要:
We propose an option approach for pricing bond illiquidity that is reminiscent of the celebrated work of Longstaff (1995) on the non-marketability of some non-dividend-paying shares in IPOs. This approach describes a quite common situation in the fixed income market: it is rather usual to find issuers that, besides liquid benchmark bonds, issue some other bonds that either are placed to a small number of investors in private placements or have a limited issue size. We model interest rate and credit risks via a convenient reduced-form approach. We deduce a simple closed formula for illiquid corporate coupon bond prices when liquid bonds with similar characteristics (e.g. maturity) are present in the market for the same issuer. The key model parameter is the time-to-liquidate a position, i.e. the time that an experienced bond trader takes to liquidate a given position on a corporate coupon bond. We show that illiquid bonds present an additional liquidity spread that depends on the time-to-liquidate aside from bond volatility. We provide a detailed application for two issuers in the European market.

中文摘要:
我们提出了一种债券非流动性定价的期权方法,这让人想起Longstaff(1995)关于IPO中一些非股息支付股票的非市场性的著名著作。这种方法描述了固定收益市场中的一种非常常见的情况:除了流动性基准债券之外,发行人通常还会发行一些其他债券,这些债券要么以私募方式交给少数投资者,要么发行规模有限。我们通过一种方便的简化方法对利率和信贷风险进行建模。当具有类似特征(如到期日)的流动债券存在于同一发行人的市场中时,我们推导出非流动公司息票债券价格的简单闭合公式。关键模型参数是平仓时间,即有经验的债券交易员平仓公司息票债券的给定头寸所需的时间。我们表明,非流动性债券表现出额外的流动性利差,这取决于除债券波动性之外的清算时间。我们为欧洲市场的两家发行人提供了详细的申请。
