We use a unique dataset of bond downgrades from a niche rating company that has been found to be reacting faster to publicly available information than its competitors. Using regime-switching models we propose risk measures to quantify stock return disturbances (distress costs) associated with...

This paper presents mathematical models for cyber breach probability as function of security spending in protecting a firm's ICT systems. We derive optimal level of security investment as percentage of value-at-risk. We show that the upper bound of optimal investment can be 1/e, 1/√2π or...
