We estimate the intensity of choice parameter in heterogenous agent models in both a static and dynamic setting. Mean-variance optimizing agents choose among mutual funds of similar styles but varying performance. Actively managed funds have a lower Sharpe ratio than passive index funds, yet...

Traders in this simulation of an asset market endogenously select from available information sources in order to maximize expected profits. The information options include two noisy signals of future dividends (the fundamentals) and a simple trend following technical trading rule. Traders use...

The paper analyzes the intensity of choice in an agent based financial optimization problem. Mean-variance optimizing agents choose among mutual funds of similar styles but varying performance. We specify a model for the allocation of new funds, switching between funds, and withdrawals and...

In a dynamic asset pricing model informed traders receive a noisy signal of the value of a risky asset while uninformed traders learn to extract the information from the price. The relative popularity of the two strategies depends on past performance. The asymptotic properties of the model and...

A counter example to the Grossman and Stiglitz (1980) finding of the impossibility of informationally efficient markets is produced using discrete choice dynamics to govern the evolution of the trader population that choose between being informed or uninformed based on past performance.

A least-squares model governs the learning process as traders attempt to extract private information from the market price of an asset. Replicator dynamics govern the evolution of the popularity of this strategy against the alternative, directly acquiring the private information through...

Investors select how to distrubute funds between a number of projects. This paper departs from the standard financial market model by endogenizing the intrinsic value of the assets to be dependend upon the amount of funding they attract. Investment strategies based on fundamental and a momentum...

In the developed model, without knowing the trading strategies of the other traders in a financial market, traders cannot derive a rational expectations equilibrium. In a dynamic setting, market participants employ learning and adaptation to develop trading strategies to accommodate for this...
