In this paper, we examine the dynamic behavior of credit spreads on corporate bond portfolios. We propose an econometric model of credit spreads that incorporates portfolio rebalancing, the near unit root property of spreads, the autocorrelation in spread changes, the ARCH conditional...

No consensus has yet emerged from the existing credit risk literature on how muchof the observed corporate-Treasury yield spreads can be explained by credit risk. In thispaper, we propose a new calibration approach based on historical default data and showthat one can indeed obtain consistent...

Recent work has suggested that strategic underperformance of debt-service obligations by equity holders can resolve the gap between observed yield spreads and those generated by Merton (1974)-style models.(...)

We examine the question of the determinants of corporate bond credit spreads using both weekly and monthly option-adjusted spreads for nine corporate bond indexes from Merrill Lynch from January 1997 to July 2002. (...)

Diversification benefits of three “hot” asset classes—Commodity, Real Estate Investment Trusts (REITs), and Treasury Inflation-Protected Securities (TIPS)—are well-studied on an individual basis and in a static setting. Using data from 1970 to 2010, this paper documents both that the...

In this paper, we propose an alternative approach for pricing and hedging non-standard American options. In principle, the proposed approach applies to any kind of American-style contract for which the payoff function has a Markovian representation in the state space. Specifically, we obtain an...

In this article, we present a new method for pricing and hedging American options along with an efficient implementation procedure. The proposed method is efficient and accurate in computing both option values and various option hedge parameters. We demonstrate the computational accuracy and...
