 ====== Free Trade - A Wealth vs. Energy Model ======
-As an experiment for [[https://www.youtube.com/watch?v=qaASCnKNTmA|a video]], I devised a computer simulation of the free trade of wealth and energy using NetLogo's free Agent-Based Modelling (ABM) software. You can view an [[https://openaccesseconomy.org/files/Free_Trade_Model_Wealth_vs_Energy.html|interactive model online]] or download the NetLogo [[https://openaccesseconomy.org/files/Free_Trade_Model_Wealth_vs_Energy.nlogo|source code]].

+The goal was to create as fair a simulation as possible of the evolution of a free market trading economy using a few simple parameters, and compare how the transfer of wealth related to the transfer of 'energy' - where energy generally denotes effort spent or quality of life received.
-  * Each agent would start with the same amount of wealth and energy. (Capital)
+A model 'world' is created and populated with agents who follow a simple set of rules. These are:
-  * Each agent would be given a randomly applied 'skill' attribute (a number of varying value, constrained to a maximum of double the lowest)
-  * Each agent would trade with a fixed number of randomly allocated 'customer' agents
-  * A 'trade' would consist of selling 1 copy of their skill as energy, divided out and paid for equally among their customers
-  * Every trade would expend 1 unit of an agent's energy (regardless of value)
-  * There is always the same amount of money in the system

-Even running the model with conservative values (say 1.5 skill variance) reveals a strong and fast trend of the rich getting richer and the poor getting poorer.

 ===== Safety net =====
-Since the model effectively 'kills' off poor agents without mercy, I decided to add a 'safety net' feature which would roughly mimic the effect of social safety nets like state welfare, charity or microloans. Once an agent is in danger of falling below this 'poverty' threshold, they are awarded an extra wealth credit freely. This credit is then taxed across all other agents equally.

-While this is an effective way to rescue agents from the poverty line, it makes little difference to the trend of the rich getting richer, except slowing it slightly.

 ===== The transfer of energy =====
-In this model, 'energy' generally refers to work effort and quality of life. ie. Agents 'spend' energy selling their product, and 'consume' energy that they purchase from other agents as quality of life. The greater the energy they have, the higher is their quality of life.
+In this model, wealth and energy are tracked independently. 'Energy' generally refers to work / effort and quality of life. ie. Agents 'spend' energy selling their product, and 'consume' energy that they purchase from other agents as quality of life.The greater the energy they have, the higher is their quality of life.
+In this simulation, all agents spend exactly 1 unit of energy 'selling' their product regardless of price. This would appear to be a fair reflection of the similar amount of effort it requires to put in a day's work regardless of salary.

 Even though some agents are 'selling' more energy than others, the net effect is that the net increase in energy across the population is roughly evenly distributed.
+===== Conclusions =====
+Even though quality of life generally increases for all agents, there is a significant cost in terms of inequality and the suction of wealth from society by the wealthy. And it's worth emphasising that there are no greed or privilege elements in this model; the gravitation of wealth to the wealthy is simply a mathematical function of their costs becoming proportionally less and less.
+When both the transfers of wealth and energy are taken equally into consideration the net benefit to society is only marginal, whereas a society hypothetically based on the transfer of energy //only// (open access) would be significantly better off.
