Financial markets are typically characterized by high (low) price level and low (high) volatility during boom (bust) periods, suggesting that price and volatility tend to move together with different market conditions/states. By proposing a simple heterogeneous agent model of fundamentalists and...

Based on Dixit-Stiglitz framework of exogenous equilibrium, the basic tax competition model is developed introducing agglomeration forces. However, the short-run dynamic micro-foundation to reach such equilibrium has long been ignored in the new economic-geography tax competition literature. In...

In this paper we examine various types of financial crises and conjecture its underlying mechanisms using a deterministic heterogeneous agent model (HAM). In a market-maker framework, forward-looking investors update their price expectation according to psychological trading windows and cluster...

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...
