We analyse the effect of differing uncertainty assumptions on the costs of shareholder-bondholder conflicts arising from partially debt-financed investments. A partial equilibrium model, valid for a large class of diffusion processes, is developed and then applied to the specific cases of a...

This paper develops a model of debt renegotiation in a structural framework that accounts for taxes, bankruptcy costs and renegotiation costs. To our knowledge, all the previous work on debt renegotiation implies an infinite number of renegotiations. This feature preempts the analysis of the...

This paper looks at divestitures by 144 UK firms listed on the London Stock Exchange from 1985 to 1991 and investigates whether and how accurately investors price the firm’s option to abandon assets in exchange for their exit value. Theory prices this real option as an American style put and...

In [4], the authors introduced a Markov copula model of portfolio credit risk. This model solves the top-down versus bottom-up puzzle in achieving efficient joint calibration to single-name CDS and to multi-name CDO tranches data. In [4], we studied a general model, that allows for stochastic...

We study to what extent firms spread out their debt maturity dates across time, which we call granularity of corporate debt. We consider the role of debt granularity using a simple model in which a firm's inability to roll over expiring debt causes inefficiencies, such as costly asset sales or...

Merton (1974) suggested a structural model for default prediction which allows using timely information from the equity market. The literature describes several specifications to the application of the model, including methods presumably used by practitioners. However, recent studies demonstrate...

Credit risk models should reflect the observation that the relevant value of collateral is generally not the average value of the asset over all possible states of nature. In most cases, the relevant value of collateral for the lender is its secondary market value in bad states of nature, where...

The standard measures of distress risk ignore the fact that firm defaults are correlated and that some defaults are more likely to occur in bad times. We use risk premium computed from corporate credit spreads to measure a firm’s exposure to systematic variation in default risk. Unlike...

We show that option prices can always be obtained as the values of simple optimization problems. This easy remark has two consequences: sensitivity analysis is simplified (by applying the envelope theorem) and numerical procedures are improved. We give two examples of applications: options on...

This paper presents new closed form solutions for the valuation of European put options and of "down-an-in" barrier options written on leveraged equity. Unlike in past literature (Toft and Prucyk, 1997) and in keeping with empirical evidence, the model allows equity to retain value even after...
