Metaphoria 2019

Timothy Gooding | Published Sunday, February 24, 2019

This model test the efficiency of the market economy in comparison with a hunter/gatherer economy. It also compares the model outcomes between a market economy when using eternal agents with one using mortal agents.

This model aims to study the dynamic propagation of individual behaviour within social networks, focusing on how normative expectations (NE) and experiential expectations (EE) jointly influence behavioural decisions. It also explores the long-term effects of different intervention scenarios (such as enhancing visibility, considering indirect social links, and education) on behavioural propagation patterns and the overall behaviour of the group.
The model was developed in NetLogo 6.4. It generates simulated groups based on large-scale survey data, utilizing NetLogo’s CSV, Table, and Matrix extensions. The model also employs the NW extension to enable network analysis functionality.
The model is designed for research “Shaping social norms to promote individual response behavior in public crises: An agent-based modeling approach” in Journal of Cleaner Production, Volume 554, 8 April 2026, 148014

Polarization

Grant Eads | Published Tuesday, November 30, 2021

A model depicting how individuals change political opinions and are influenced by others with similar opinions, and how those people form into groupings. We also model the impact that a large amount of unchanging, automatic agents impact the established groupings

Peer reviewed Artificial Anasazi

Marco Janssen | Published Tuesday, September 07, 2010 | Last modified Saturday, April 27, 2013

Replication of the well known Artificial Anasazi model that simulates the population dynamics between 800 and 1350 in the Long House Valley in Arizona.

A simple model is constructed using C# in order to to capture key features of market dynamics, while also producing reasonable results for the individual insurers. A replication of Taylor’s model is also constructed in order to compare results with the new premium setting mechanism. To enable the comparison of the two premium mechanisms, the rest of the model set-up is maintained as in the Taylor model. As in the Taylor example, homogeneous customers represented as a total market exposure which is allocated amongst the insurers.

In each time period, the model undergoes the following steps:
1. Insurers set competitive premiums per exposure unit
2. Losses are generated based on each insurer’s share of the market exposure
3. Accounting results are calculated for each insurer

In this agent-based model, agents decide to adopt a new product according to a utility function that depends on two kinds of social influences. First, there is a local influence exerted on an agent by her closest neighbors that have already adopted, and also by herself if she feels the product suits her personal needs. Second, there is a global influence which leads agents to adopt when they become aware of emerging trends happening in the system. For this, we endow agents with a reflexive capacity that allows them to recognize a trend, even if they can not perceive a significant change in their neighborhood.

Results reveal the appearance of slowdown periods along the adoption rate curve, in contrast with the classic stylized bell-shaped behavior. Results also show that network structure plays an important role in the effect of reflexivity: while some structures (e.g., scale-free networks) may amplify it, others (e.g., small-world structure) weaken such an effect.

NetLogo agent-based model to simulate the transmission of COVID-19 in a university dormitory. User can set the number of initial students, buildings, floors, rooms, number of initially infected, and transmission rate. They can also test the effect of masks, sanitizations, elevator allowance, and visits on the effect of the SEIR curve.

TRAINING AND TURNOVER

Kehinde Salau | Published Tuesday, December 16, 2008 | Last modified Saturday, April 27, 2013

The purpose of the model presented by Glance et al is to study the ‘contribute vs. free-ride’ dilemma present in organizations.

Village Ecodynamics Project

ipem | Published Friday, May 13, 2011 | Last modified Saturday, April 27, 2013

The Village Project is designed to help archaeologists understand the factors influencing settlement patterns of small-scale agrarian peoples. Although such societies are becoming increasingly rare, they represent the norm throughout most of the Neolithic period the world over.

Transitions between homophilic and heterophilic modes of cooperation

Genki Ichinose | Published Sunday, June 14, 2015 | Last modified Sunday, November 14, 2021

In our model, individual agents are distributed over a two-dimensional square lattice. The agents play the prisoner’s dilemma game with their neighbors, imitate the highest strategy, and then migrate to empty sites based on their tag preference.
