Growing Unpopular Norms. A Network-Situated ABM of Norm Choice.

C Merdes | Published Tue Nov 22 21:11:26 2016 | Last modified Sat Mar 17 18:41:43 2018

The model’s purpose is to provide a potential explanation for the emergence, sustenance and decline of unpopular norms based on pluralistic ignorance on a social network.

PolicySpace models public policies within an empirical, spatial environment using data from 46 metropolitan regions in Brazil. The model contains citizens, markets, residences, municipalities, commuting and a the tax scheme. In the associated publications (book in press and we validate the model and demonstrate an application of the fiscal analysis. Besides providing the basics of the platform, our results indicate the relevance of the rules of taxes transfer for cities’ quality of life.

Machine Learning simulates Agent-based Model

This is an initial exploratory exercise done for the class @ Text available here:
The program:
Reads output from an ABM model and its parameters’ configuration
Creates a socioeconomic optimal output based on two ABM results of the modelers choice
Organizes the data as X and Y matrices
Trains some Machine Learning algorithms

Extended Flache and Mas (2008)

Hadi Aliahmadi | Published Wed Aug 16 22:32:04 2017 | Last modified Mon Feb 26 20:03:46 2018

We extend the Flache-Mäs model to incorporate the location and dyadic communication regime of the agents in the opinion formation process. We make spatially proximate agents more likely to interact with each other in a pairwise communication regime.

A simple agent-based spatial model of the economy

Bernardo Alves Furtado Isaque Daniel Rocha Eberhardt | Published Thu Mar 10 18:26:16 2016 | Last modified Tue Nov 22 15:08:38 2016

The modeling includes citizens, bounded into families; firms and governments; all of them interacting in markets for goods, labor and real estate. The model is spatial and dynamic.

This is an adaptation and extension of Robert Axtell’s model (2013) of endogenous firms, in Python 3.4

Land Use in the Chitwan Valley

Alex Zvoleff | Published Mon Jun 2 01:42:22 2014

chitwanabm is a spatially explicit agent-based model of population and land use in the Chitwan Valley, Nepal, designed to explore feedbacks between population and environment, with a heavy focus on community context and individual-level variation.

This Python module contain a function that is able to test the ergodicity of a given agent based model. It is sufficient to produce one long time series and many smaller time series. The function uses

Stationarity Test

This is a stationarity test, it tests whether a given moment is constant during the time series (null hypothesis). The Wald Wolfowitz nonparametric fitness test is applied to time series.
