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...

After Hurricane Andrew the U.S. Congress entertained proposals to allow insurers to employtax-deferred loss reserves. Interest was strong at first, but as the events receded interestwaned. After the most recent hurricane seasons, interest in the proposals has rejuvenated. Weexamine the use of...

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...

This paper presents analytical models for optimizing firm's cybersecurity spending and cyber insurance based on the effectiveness of spending in reducing cyber threats, vulnerability and impact, respectively. At the macro-level, the paper shows how private-sector contribution toward countering...

In this paper we present a conceptual framework for regulatory and policy responses to systemic risks, in light of lessons learned from the recent financial crisis. We argue that capitalism works best when it facilitates fair market discovery of prices. However, the market is imperfect; there...

The purpose of this paper is to build a modeling and pricing framework to investigate the sustainability of the Home Equity Conversion Mortgage (HECM) program in the United States under realistic economic scenarios, i.e., whether the premium payments cover the fair premiums for the inherent...

In this paper we propose a Good Asset Purchase Plan (GAPP), as a cure for the falling U.S. housing market and a stimulus for economic recovery. The central theme of the plan is that the U.S. Government directly purchases minority shares (say, up to 20%) of good assets such as residential...

In this paper, we investigate the relationship between comonotonicity and stoploss order. We prove our main results by using a characterization of stop-loss order within the framework of Yaari's (1987) dual theory of choice under risk. Wang and Dhaene (1997) explore related problems in the case...
