One explanation for overpricing on asset markets is a lack of traders' self-control. Self-control is the individual capacity to override or inhibit undesired impulses that may drive prices. We implement the first experiment to address the causal relationship between self-control abilities and...

We propose a continuous-time heterogeneous agent model consisting of fundamental, momentum, and contrarian traders to explain the significant time series momentum. We show that the market under-reacts in short-run and overreacts in long-run when momentum traders dominate the market, which...

This paper proposes the generalized use of fractional Brownian motion in a multifractal trading time framework to reveal variation in the index price diffusion process that appears before and after 'extreme' events of distinct origin. "Crashes" following internal self-organization and those...

We study trading behavior and the properties of prices in informationally complex markets. Our model is based on the single-period version of the linear-normal framework of Kyle (1985). We allow for essentially arbitrary correlations among the random variables involved in the model: the value of...

We propose a continuous-time heterogeneous agent model consisting of fundamental, momentum, and contrarian traders to explain the significant time series momentum. We show that the performance of momentum strategy is determined by both time horizon and the market dominance of momentum traders....

This discussion paper resulted in a publication in the <I>Journal of Economic Dynamics & Control</I>. Volume 33(11), pp. 1912-1928.<P> This paper formalizes the idea that more hedging instruments may destabilize markets when traders are heterogeneous and adapt their behavior according to experience based...</p></i>

We introduce a heterogeneous agent asset pricing model in continuoustime to show that trend chasing, switching and herding all contribute to market volatility in price and return and volatility clustering, but their impact are different. On the one hand, the fluctuations of market price and...

Asset pricing theorists have recently started to study the market impact of differences in beliefs among participants. The analysis is often carried out in the framework of Radner's perfect foresight ('rational expectations') equilibrium. Here, we study when this makes sense. In particular, we...

Suppose Rational Expectations Equilibriums (REE) that are inferred at time t materialize at time t+1. This study provides formal theoretical and empirical evidence that performance effects of skewness preference simultaneously can be evidence for demonstrations of full rationality (expertise),...
