Jamel: Java Agent-based MacroEconomic Laboratory

The structure of an economic model that is relevant to a capitalist economy needs to include the interrelated balance sheets and income statements of the units of the economy.

Hyman Minsky (1996)

An agent-based macroeconomic simulator

Jamel (Java Agent-based MacroEconomic Laboratory) is a cross-platform macroeconomic simulator developed in Java. This application leads to an agent-based computational macroeconomic model with endogenous money (about the model).

Jamel as an applet

Jamel is available as an applet, and can be directly executed by browsers for many platforms without any installation (Java 1.6 is required - How do I test whether Java is working on my computer?).

The first time you visit this page, you may have to wait a few minutes for the applet to be loaded. Then click on the New Simulation button to launch a simulation.

A virtual laboratory

Jamel is designed as a virtual laboratory, in which the user can define the conditions of an experience, through describing the initial conditions of the studied economy (number and type of agents, behaviour parameters), eventually completed by the introduction of 'exogenous' shocks at given date. We follow 'in real time' the effects of these shocks on the system behavior, observing the main macroeconomics indicators (income distribution, unemployment, inflation, money velocity, inventory levels, capacity utilization, bankruptcies...).

Code source and documentation

Jamel is a free software project targetting the Java platform. It is provided 'as is', without warranty of any kind. The application and its code source are distributed under the terms of the General Public Licence (GPL).

I started to publish the code source of the application, together with its documentation. Fives packages with classes and interfaces for markets, monetary and real objects are already available: Code source and documentation (Last update : december 2010).
