Titel:
A fractional credit model with long range dependent hazard rate 
Abstract:
Motivated by empirical evidence of long range dependence in macroeconomic variables like interest rates, domestic gross products or supply and demand rates, we propose a fractional Brownian motion (fBm) driven model to describe the dynamics of the short rate in a bond market as well as the default rate for possible default. We aim at results analogous to those achieved in recent years for affine models. We start with a bivariate fractional Vasicek model (with time dependent coefficient functio...    »
