By applying the deterministic heterogenous agent model developed by Huang et al. [Financial crises and interacting heterogeneous agents. <italic>Journal of Economic Dynamics and Control</italic> 34, no. 6: 1105--22], this paper examines the phenomena of asymmetric returns, gradual bubbles and sudden crashes. It...

We propose a two-market heterogeneous agents model with coupling mechanism to study Financial crisis with contagion effect. It manages to calibrate sudden crash behavior of US and UK stock markets during "Black Monday" of 1987 besides smooth crisis and disturbing crisis categorized in...

Conventional economic beliefs that 'equilibrium' is better than 'disequilibrium' and 'stability' is better than 'fluctuation' are challenged with a heterogeneous oligopolistic model that consists of a naive firm and a group of sophisticated firms. The naive firm is assumed to adopt a simple...

In this paper we examine assets price deviation in a multi-market system with heterogeneous investors in each market. Coupled map lattices (CML) is introduced to the market maker framework. It results in market cluster sharing the same sign of deviation in the chaotic interval. Distribution...

With the development of globalization and regional market integration, regional markets with common currency emerge. We develop a heterogeneous agents model based on the frameworks of Day and Huang (1990) as well as Westerhoff and Dieci (2006). Two markets using same currency are populated by...

Though the price-volume relations are widely documented by practitioners and empirical studies, few theoretical models can reproduce these relations and provide persuasive arguments. By simply generalizing the classical market maker framework, our heterogeneous agent model not only simulates...
