The Eurace@Unibi Model

The Eurace@Unibi model provides a representation of a closed macroeconomic model with a spatial structure. The main objective is to provide a micro-founded macroeconomic model that can be used as a unifi ed framework for policy analysis in different economic policy areas and for the examination of generic macroeconomic research questions. In spite of this general agenda the model has been constructed with certain specific research questions in mind and therefore certain parts of the model, e.g. the mechanisms driving technological change, have been worked out in more detail than others.

The Eurace@Unibi model presented here is based on the agent-based macroeconomic simulation platform developed within the EURACE  project. After the completion of the EURACE project in Nov. 2009 a group consisting of Herbert Dawid, Simon Gemkow, Philipp Harting, Michael Neugart and Sander van der Hoog has extended and altered the model substantially in numerous directions leading to the current version of the model.

The model can be executed in the ETACE Virtual Appliance.

Ongoing Research Using the Eurace@Unibi Model

The Eurace@Unibi model is used for several economic policy studies:

  • The effects of different kinds of innovation policies in economies with heterogeneous regions and spatial factor flows.
  • The effects of stabilization policies on technological change and economic growth.
  • The effects of technological change on the transformation of skill heterogeneity into wage inequality (SFB 882 project description).
  • The effects of Basel II/III banking regulation on the financial fragility of the macroeconomic system.

FLAME Simulation Framework

The Eurace and Eurace@Unibi models are implemented in the simulation framework FLAME.

FLAME (Flexible Large-scale Agent Modelling Environment) is a generic agent-based modelling system. It is a program generator which can be used to develop agent-based applications that can be compiled and built on the majority of computing systems ranging from laptops to high-performance super computers and grid systems, and works under Linux, MacOS or Windows.

FLAME programs can be compiled as serial code (single CPU use) or parallel code (for multi-node systems such as grids), and links in the message board library Libmboard to provide MPI (Message Passing Interface) facilities.

Overview

The ETACE Virtual Appliance is a stand-alone Linux-based simulation platform that provides a full suite of programmes for (large-scale) agent-based modelling and simulation. It builds on the core Flexible Large-scale Agent Modelling Environment (FLAME), adding programs such as Graphical User Interfaces, an editor for agent-based model design and an integrated solution for data visualisation using R.


Aims

The idea behind the software package is to make every step related to the initialization, simulation and analysis of the Eurace@Unibi model as easy as possible. The following versions of the model are included:


Purpose

The programme suite allows Academics, Practitioners, Regulators, and the general public to create, edit, and simulate models that have been developped using the Flame agent-based modelling environment, such as the Eurace@Unibi model.

The virtual appliance serves multiple purposes: (i) to ensure the reproducibility of results, (ii) as a form of model documentation and communication, (iii) it heightens the credibility of the model.


For questions and support

We regret that we do not have the capacity to support you in any way, shape, or form. The Virtual Appliance is provided as is, without any warranty that it will work. We do however appreciate any remarks, comments, or suggestions for improvement, or other hints that you may have, and would appreciate any and all feedback on the following email address: etace@wiwi.uni-bielefeld.de
