1. In a computer system, a method for pricing equity securities and fixed-income securities having a no arbitrage constraint, the method comprising:
- determining a fixed-income security pricing based on an inflation value, a real rate value and a term structure parameter;
determining equity security pricing based on the inflation value, the real rate value, the term structure risk parameter, a dividend growth value, and an equity correlation parameter; and
generating pricing data corresponding to the fixed-income security pricing and the equity security pricing.

Abstract
The pricing module of the present invention provides a single module that models both fixed-income securities and equity securities into the future in an arbitrage-free model. Because the modeling includes both fixed-income securities and equity securities that are modeled based on common input state variables and does not allow arbitrage conditions between the fixed-income securities and the equity securities (as well as no arbitrage within a security class), the present invention provides an improved pricing module as compared to those in the prior art.

24. In a computer system, a method for pricing equity securities and fixed-income securities having a no arbitrage constraint, the method comprising:
-
determining a term structure risk parameter based on observed term structure data; determining an equity correlation parameter based on a correlation between equity dividends and fixed-income securities; determining a heteroskedastic inflation value; determining a heteroskedastic real rate value; determining a homoskedastic dividend growth value; pricing fixed-income securities based on the term structure risk parameter, the inflation value and the real rate value; and pricing equity securities based on the term structure risk parameter, the inflation value, the real rate value, the dividend growth value, and the equity correlation parameter; and generating pricing data corresponding to the fixed-income security pricing and the equity security pricing.

25. A system for analyzing asset portfolios comprising:
-
a value module that provides one or more values; a pricing kernel communicably coupled to the value module, the pricing kernel to generate prices for fixed-income securities based on a term structure risk parameter, an inflation value and a real rate value and to generate prices for equity securities based on the term structure risk parameter, the inflation value, the real rate value, a dividend growth value, and an equity correlation parameter, wherein the pricing of fixed-income securities and the pricing of equity securities are subject to a no arbitrage constraint; and a simulation module communicatively coupled to the pricing kernel, the simulation module to estimate future asset worth based on the prices generated by the pricing kernel, the simulation module to generate pricing data corresponding to the fixed-income security pricing and the equity security pricing. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. An apparatus for pricing fixed-income securities and equity securities having a no arbitrage constraint, comprising:
-
an input device; an output device; and a processor coupled to the input device and to the output device to output pricing of fixed-income securities and equity securities, wherein fixed-income securities are priced based on a term structure risk parameter, an inflation value and a real rate value, and further wherein equity securities are priced based on the term structure risk parameter, the inflation value, the real rate value, a dividend growth value and an equity correlation parameter. - View Dependent Claims (37, 38, 39)
