A Financial Market Model Incorporating Herd Behaviour

Christopher M. Wray, Steven R. Bishop, Daniele Marinazzo
2016 PLoS ONE  
While numerous studies investigate herd behaviour in financial markets, it is often considered without reference to the pricing of financial instruments or other market dynamics.  ...  Here, a trader interaction model based upon informational cascades in the presence of information thresholds is used to construct a new model of asset price returns that allows for both quiescent and herd-like  ...  Feng, et al [39] suggests one reason for the lack of acceptance of agent-based financial market models is the insufficient quantitative accuracy of such models-and the paper advocates combining an agent-based  ...

Preface to the special feature

Akira Namatame
2015 Evolutionary and Institutional Economics Review  
Many studies analyze the socioeconomic systems such as cascading failures and financial stability issues using network theory and agent-based modeling.  ...  Agent-based modeling provides answers to questions where traditional analysis methods are weak, and it is leading to improved models across wide types of financial risks.  ...  The authors show that agent-based modeling is useful in order to study market dynamics and acquire information to devise market rules.  ...

Market Efficiencies and Market Risks

Pierre André Maugis
2010 Social Science Research Network  
In recent years numerous papers constructed or simulated financial markets at an agent level, aiming to explain the non-stationarity of price processes.  ...  By modeling agents as black boxes that receive information that they transform into an output information, information according to which they then act upon the financial market, we show that the diversity  ...  So the key concept to be studied is the propagation of the information: from the agent level to the market level, from the market level to the agent level and in-between agents.  ...

A queueing theory description of fat-tailed price returns in imperfect financial markets

H. Lamba
2010 European Physical Journal B : Condensed Matter Physics  
Such an approach may prove useful in the development of mathematical models for rapid deleveraging and panics in financial markets, and the stress-testing of financial institutions.  ...  In a financial market, for agents with long investment horizons or at times of severe market stress, it is often changes in the asset price that act as the trigger for transactions or shifts in investment  ...  agent' to model an entire economy.  ...

Decision Making in Ignorance and Consequent Market Outcomes: Equilibrium Analysis

Partha Gangopadhyay
2011 Modern Applied Science  
The main innovation of this paper is to make rational decision-maker aware of the adverse consequences of informational, or information, cascades in markets characterised by ignorance due to their uncertain  ...  This paper offers for the first time, to the best of our understanding, a simple modelling of a market with uncertain and dynamic environments and explains the existence of an equilibrium that is immune  ...  An informational cascade signifies a situation in which subsequent agents, based on the observations of others, makes the same choice independent of their private signals.  ...
