This paper analyzes a structural model of corporate debt in the spirit of Leland (1994) model within a more realistic general context where payouts and asymmetric tax-code provisions are introduced. We analytically derive the value of the tax benefit claim in this context and study the joint...

In this paper a structural model of corporate debt is analyzed following an approach of optimal stopping problem. We extend Leland model [5] introducing a dividend paid to equity holders and studying its effect on corporate debt and optimal capital structure. Varying the parameter affects not...

Equity returns and firm's default probability are strictly interrelated financial measures capturing the credit risk profile of a firm. Following the idea proposed in [20] we use high-frequency equity prices in order to estimate the volatility risk component of a firm within Merton [17]...

We want to recover the transition kernel P of a Markov chain X when only a sub-sequence of X is available. The time gaps between the observations are iid with unknown distribution. We propose a method to build an estimator of P under the assumption that it has some zero entries. Its asymptotic...

This paper analyzes the capital structure of a firm in an infinite time horizon following Leland (1994) under the more general hypothesis that the firm’s assets value process belongs to a fairly large class of stochastic volatility models. By applying singular perturbation theory, we fully...

We consider financial market models based on Wiener space with two agents on different information levels: a regular agent whose information is contained in the natural filtration of the Wiener process W, and an insider who possesses some extra information from the beginning of the trading...

We deal with the problem of outsourcing the debt for a big investment, according two situations: either the firm outsources both the investment (and the associated debt) and the exploitation to a private consortium, or the firm supports the debt and the investment but outsources the...

This paper is the sequel of a paper by the authors (1993) and it has a complete version in (1995). We develop a stochastic calculus which allows to integrate non-adapted processes taking their values in the space of second-order 1-forms that are above a manifold valued anticipating process....

In this paper, generalizing results in Alòs, León and Vives (2007b), we see that the dependence of jumps in the volatility under a jump-diffusion stochastic volatility model, has no effect on the short-time behaviour of the at-the-money implied volatility skew, although the corresponding Hull...

We develop a financial model with an "influential informed" investor who has an additional information and influences asset prices by means of his strategy. The prices dynamics are supposed to be driven by a Brownian motion, the informed investor's strategies affect the risky asset trends and...
