WHAT IS IT?

This model WealthDistribRes can be used to study the distribution of wealth in function of using a combination of resources classified in two renewable and nonrenewable.
This agent-based computational model created in NetLogo 4.0.5 has the following fundamental characteristics:
(i) the turtles are of two types: female and male;
(ii) these turtles have a limited life expectancy determined by the parameters LifeExpectancyMax (maximum life expectancy) and LifeExpectancyMin (minimum life expectancy);
(iii) patches stores a certain amount of water ResWater?0, a certain amount of food ResFood?0, a certain amount of coal ResCoal?0, a certain amount of oil ResOil?0, a certain amount of gas ResGas?0, a certain amount of uranium ResUranium?0, a certain amount of wind ResWind?0, a certain amount of sun ResSun?0, a certain amount of tides ResTides ?0, and a certain amount of geothermal heat ResGeothermalHeat?0; all these resources are converted in energy; these ten resources are divided in two: the first type are renewable resources and here are included water, food, wind, geothermal heat, tides and sun resources that are replenished on every simulation step; the second type are nonrenewable resources (coal, oil, gas, uranium);
(iv) a male and female turtle can create a couple, and a number of children;
(v) the children can inherit the wealth of their parents;
(vi) the needs of every turtle are 1 of energy per one year processed from the available resources found on the patches;
(vii) if these basic needs are not fulfilled then the respective turtle dies.

HOW IT WORKS

The model has the following buttons:
- <Setup> - that declare and setup parameters, initial variables, agents and patches
- <Go> - Start the simulation and stop the simulation when 1000 simulation steps passed or there are no agents;
- <rs> - set the random seed in the interval {-2, -1, 0, 1, 2}.
In addition, the interface tab has the following monitors:
- Low - the number of turtles of low social class;
- Medium - the number of turtles of medium social class;
- High - the number of turtles of high social class;
- AvgVisionLow - the average vision of low class;
- AvgVisionMedium - the average vision of medium class;
- AvgVisionHigh - the average vision of high class;
- WealthLow - the average wealth of low class;
- WealthMedium - the average wealth of medium class;
- WealthHigh - the average wealth of high class.
The user can modify the following sliders that set the efficiency of processing resources: EfficiencyProcessingFood, EfficiencyProcessingWater, EfficiencyProcessingWind, EfficiencyProcessingSun, EfficiencyProcessingTides, EfficiencyProcessingGeoHeat, EfficiencyProcessingCoal, EfficiencyProcessingOil, EfficiencyProcessingGas, and EfficiencyProcessingUranium.
