The Ghost in the Model (and Other Effects of Floating Point Arithmetic)

Polhill, J. Gary; Izquierdo, Luis R.; Gotts, Nicholas M. - In: Journal of Artificial Societies and Social Simulation 8 (2004) 1, pp. 5-5

This paper will explore the effects of errors in floating point arithmetic in two published agent-based models: the first a model of land use change (Polhill et al. 2001; Gotts et al. 2003), the second a model of the stock market (LeBaron et al. 1999). The first example demonstrates how branching...

Simulating Online Business Models

Schuster, Stephan; Gilbert, Nigel - Volkswirtschaftliche Fakultät, … - 2004

The online content market for news and music is changing rapidly with the spread of technology and innovative business models (e.g. the online delivery of music, specialised subscription news services). It is correspondingly hard for suppliers of online content to anticipate developments and the...

Modelling the effect of learning and evolving rules on the use of common-pool resources

Smajgl, Alexander - Society for Computational Economics - SCE - 2004

The extend to which common-pool resources are used and managed sustainably depends highly on incentives. Incentives influence the behaviour of individuals with respect to natural resource management and are determined by institutional arrangements comprising of formal and informal rules and...

Simulating knowledge dynamics in innovation networks (SKIN)

Ahrweiler, Petra; Pyka, Andreas; Gilbert, Nigel - 2004

An agent-based simulation model representing a theory of the dynamic processes involved in innovation in modern knowledge-based industries is described. The agent-based approach allows the representation of heterogeneous agents that have individual and varying stocks of knowledge. The simulation...

SYLVOPAST: a Multiple Target Role-Playing Game to Assess Negotiation Processes in Sylvopastoral Management Planning

Etienne, Michel - In: Journal of Artificial Societies and Social Simulation 6 (2003) 2, pp. 5-5

After a brief description of the framework of the model developed to simulate vegetation dynamics, fire propagation and agentsâ€™ behaviour, the role-playing game rules are presented and related to the different points they are supposed to deal with: climatic hazard, animal grazing, forest...

An Agent-Based Model of Ethnic Mobilisation

Srbljinovic, Armano; Penzar, Drazen; Rodik, Petra; … - In: Journal of Artificial Societies and Social Simulation 6 (2003) 1, pp. 1-1

In this paper we used the methodology of agent-based modelling to help explaining why populations with very similar …, ideas and modelling constructs that were already used in agent-based modelling of social processes. The model has been …

Agent-based modelling - A methodology for the analysis of qualitative development processes

Grebel, Thomas; Pyka, Andreas - Institut für Volkswirschaftlehre, Fakultät für … - 2003

focused on stylized empirical phenomena. With agent-based modelling, however, the trade-off between simplicity in modelling … serves as a basic instruction on how to model qualitative change using an agent-based modelling procedure. The necessity to … focus on qualitative change is discussed, agent-based modelling is explained and finally an example is given to show the …

A computational view of market efficiency

Hasanhodzic, Jasmina; Lo, Andrew; Viola, Emanuele - In: Quantitative Finance 11 (2011) 7, pp. 1043-1050

We study market efficiency from a computational viewpoint. Borrowing from theoretical computer science, we define a market to be efficient with respect to resources S (e.g., time, memory) if no strategy using resources S can make a profit. As a first step, we consider memory-m strategies whose...

Econophysics review: II. Agent-based models

Chakraborti, Anirban; Toke, Ioane Muni; Patriarca, Marco; … - In: Quantitative Finance 11 (2011) 7, pp. 1013-1041

This article is the second part of a review of recent empirical and theoretical developments usually grouped under the heading Econophysics. In the first part, we reviewed the statistical properties of financial time series, the statistics exhibited in order books and discussed some studies of...
