06 EiLab V1.36 – Entropic Index Laboratory (version 1.3.0)

There is a new type of economic model called a capital exchange model, in which the biophysical economy is abstracted away, and the interaction of units of money is studied. Benatti, Drăgulescu and Yakovenko described at least six capital exchange models – now referred to as the BDY models – which are replicated as models A through H in EiLab. In recent writings, Yakovenko goes on to show that the entropy of these monetarily isolated systems rises to a maximal possible value as the model approaches steady state, and remains there, in analogy of the 2nd law of thermodynamics. EiLab demonstrates this behaviour. However, it must be noted that we are NOT talking about thermodynamic entropy. Heat is not being modeled – only simple exchanges of cash. But the same statistical formulae apply.

In three unpublished papers available with this model, the concept of “entropic index” is defined for use in agent-based models (ABMs), with a particular interest in sustainable economics. Models I and J of EiLab are variations of the BDY model especially designed to study the Maximum Entropy Principle (MEP – model I) and the Maximum Entropy Production Principle (MEPP – model J) in ABMs. Both the MEPP and H.T. Odum’s Maximum Power Principle (MPP) have been proposed as organizing principles for complex adaptive systems. The MEPP and the MPP are two sides of the same coin, and understanding of their implications is key, I believe, to understanding economic sustainability. Both of these proposed (and not widely accepted) principles describe the role of entropy in non-isolated systems in which complexity is generated and flourishes, such as ecosystems, and economies.

EiLab is one of several models exploring the dynamics of sustainable economics – PSoup, ModEco, EiLab, OamLab, MppLab, TpLab, and CmLab.

Release Notes

Models A through H are complete replications of BDY models. Model I (complete) is designed for study of an analogy of the 2nd law of thermodynamics. Model J (incomplete) is designed for study of an analogy of the proposed 4th law of thermodynamics, commonly referred to as either the MEPP, or MPP. Study of the MPP has proceeded with other models in the series, but I intend to return to model J to explore improvements in its design, and the insights it can provide.

This is a work in progress. There are lots of options for data export to MS Excel in CSV format. It is a bench tool, and not meant for careless use. Any help available is in the IWiz panels, or MLRSN panels, or the included documentation. Read those carefully.

BUT, it will fail if you ask it to do some things. Not all components of a windows application have been added or tested. Do not save the results of any run. Do not use the help features of a standard windows application (e.g. the F1 key).
