This paper aims at increasing our insights into the way financial markets respond to news. We view the market as a (nonlinear) filter of news on fundamentals. A stylized version of this situation is obtained by considering by a time dependent dividend rate which is driving the market. To model...

Option pricing model with non-constant volatility models are compared to stochastic volatility ones. The non-constant volatility models considered are the Dupire's local volatility and Hobson and Rogers path-dependent volatility models. These approaches have the theoretical advantage 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...

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...

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...

Base rate neglect has been shown to be a very robust bias in human information processing. It has also been show to be ecologically rational in some environments. However, when arguing about base rate neglect usually isolated individuals are considered. I complement these results by showing that...

We study the extent to which self-referential adaptive learning can explain stylized asset pricing facts in a general equilibrium framework. In particular, we analyze the effects of recursive least squares and constant gain algorithms in a production economy and a Lucas type endowment economy....

In this paper we analyze a dynamic, asset pricing model where an arbitrary number of heterogeneous, procedurally rational investors divide their wealth between two assets. Both fundamental dividend process and behavior of traders are modeled in a very general way. In particular, agents' choices...

Centralized exchange has a worst-case size-complexity many orders of magnitude lower than decentralized monetary exchange for the same number of agents and goods. A more rapid approach to competitive equilibrium may therefore be possible through centralized exchange. An additional benefit of...

We consider a simple pure exchange economy with two assets, one riskless, yielding a constant return, and one risky, paying a stochastic dividend, and we assume trading to take place in discrete time inside an endogenous price formation setting. Traders demand for the risky asset is expressed as...
