CREDIT RISK MODELING USING TIME-CHANGED BROWNIAN MOTION

Motivated by the interplay between structural and reduced form credit models, we propose to model the firm value process as a time-changed Brownian motion that may include jumps and stochastic volatil...

We consider structural credit modeling in the important special case where the log-leverage ratio of the firm is a time-changed Brownian motion (TCBM) with the time-change taken to be an independent i...

We provide a surprising new application of classical approximation theory to a fundamental asset-pricing model of mathematical finance. Specifically, we calculate an analytic value for the correlatio...
IS BROWNIAN MOTION NECESSARY TO MODEL HIGH-FREQUENCY DATA?
Semimartingale Brownian motion jumps finite activity infinite activity discrete sampling high frequency
2014/3/13
This paper considers the problem of testing for the presence of a continuous part in a semimartingale sampled at high frequency. We provide two tests, one where the null hypothesis is that a continuou...

Truncated Variation Brownian Motion Applications

In [6] for c > 0 we defined truncated variation, T V c μ , of Brownian motion with drift, Wt = Bt+μt, t 0, where (Bt) is a standard Brownian motion.

In this paper we study Backward Stochastic Differential Equations with two reflecting right continuous with left limits obstacles (or barriers) when the noise is given by Brownian motion and a Poisson...
