We construct an empirical measure of market frictions in the corporate market based on the difference between the corporate bond spread and the credit default swap spread for a large number of firms in a new, large dataset that we construct. Under fairly standard assumptions, the two spreads...

When one constructs long-term investment plan, one needs to consider the fact that long-term bonds are still exposed to inflation risk. This paper studies the intertemporal portfolio-consumption decision where the investment opportunities include "inflation-indexed bonds" -- a modern financial...

The research on financial engineering by means of genetic programming is gradually popular and appealing. For example, Kaboudan (1999, 2001) and Iba and Sasaki (1999), Iba and Sasaki (1999), used standard GP to evolve forecasting models. Neely, et al. (1997), Allen and Karjalainen (1999), Fyfe...

A popular argument states that most of the diversification in a portfolio can be obtained with a rather small number of securities. In this paper we present three algorithms to approach the underlying NP-hard problem of portfolio optimization with a cardinality constraint. All three of these...

Various Computational Intelligence (CI) tools have been devised to depict the essential learning or adapting processes people adopt when they are making decisions. If the learning process people possess is indeed well described by some CI algorithms, then there arise an interesting question:...

We present an spectral numerical method for the numerical valuation of bonds with embedded options. We use a CIR model for the short term interest rate. The method is based in a Galerkin formulation of the relevant partial differential equation for the value of the bond discretized by means of...

This paper reports on the use of multi-agent games to model financial markets. Our research employs multi-agent games to address three questions which are of great practical importance in quantitative finance: how profit opportunities may be identified, large price movements predicted, and...

This paper investigates whether insiders use private information in their decision to exercise executive stock options. Consistent with existing research, exercises overall do not yield subsequent abnormal returns. Categorising exercises by the proportion of stock sold at exercise yields a...

This paper uses an evolutionary approach incorporating the idea of natural selection to examine market behavior in a one-sided buyer auction market. Even with no traders' rationality (such as rational expectations and adaptive learning) and with each trader's behavior preprogrammed with its own...
