Built a functioning economy engine based on the paper Emergent Economies for Role Playing Games by Jonathon Doran and Ian Parberry. By giving the program a resource desire and base output per person, the engine will find a price each programmed person will pay for a good, how many people are needed to reach an equilibrium for supply and demand, and will adjust these numbers based on given environmental factors (floods, droughts, and fires).
