Pricing commercial mortgages and their mortgage-backed securities

This article has taken considerable effort to accurately model the complexity of a commercial mortgage and its mortgage-backed security. In fact, it is the first example in the general literature on mortgage pricing to present a comprehensive set of numerical results in which the valuation of a mortgage-backed security is explicitly tied to that of the underlying mortgage. The conclusion we reach is that option pricing provides an accurate and flexible approach to valuing the complex mortgage instruments now being developed in the financial community.     

Pricing securities with multiple risks: A case of exchangeable debt

Building on the work of Das and Sundaram (2007), we develop a widely applicable model to price securities subject to interest rate, equity, and default risks and use it to price exchangeable bonds. The extension features a trivariate recombining lattice instead of the original model’s bivariate recombining lattice. We also show how to estimate some critical non-observable inputs to implement the model by using current market data so that the model’s prices reflect current market information. We test the model on a sample of exchangeable bonds to determine the model’s empirical performance. Besides exchangeable bonds, we can also use the model to price securities such as reverse exchangeable bonds, bonds exchangeable to indexes, and bonds exchangeable to commodities.     

Pricing mortgage-backed securities in a multifactor interest rate environment: a multivariate density estimation approach

Multivariate density estimation (MDE) suggests that mortgage-backedsecurity (MBS) prices can be well described as a function ofthe level and slope of the term structure. We analyze how thisfunction varies across MBSs with different coupons. An importantfinding is that the interest rate level proxies for the moneynessof the option, the expected level of prepayments, and the averagelife of the cash flows, while the term structure slope controlsfor the average rate at which these cash flows should be discounted.     

Regulating securities analysts

We examine the effects of regulations designed to address the potential conflict of interest that arises when sell-side analyst research is not independent of investment banking. We focus on two types of regulation: (1) internal barriers between equity research and investment banking that restrict communication; and (2) disclosure requirements relating to analyst compensation. We find that information barriers can increase research effort and improve report quality by limiting an investment bank's ability to distort its analyst's incentives. However, this type of regulation can also reduce information production and lower the quality of reports if an investment bank benefits directly from research activity. Disclosure requirements, on the other hand, unambiguously lead to more informative prices and a higher report quality relative to either information barriers or no regulation.     

发行通货膨胀指数化债券探讨

按一只债券在整个生命期内其未来现金流(包括本金和利息)是否固定,分为固定利率债券和浮动利率债券.其中浮动利率债券的未来现金流=利差 参考指数.当参考指数是与通货膨胀相关的指数时,这类债券就可以称为通胀指数债券(IIS).

Performance based mortgage-backed securities indexing

The traditional approaches to indexing first developed for equities and then adapted to bonds are not effective for mortgage-backed securities. This paper details a new technique for indexing portfolios of mortgage-backed securities which rectifies the deficiencies of the older cellular method. By focusing on the performance characteristics of the bonds adjusted for their embedded options, we at once simplify the process of portfolio selection and increase the accuracy of performance tracking.
