The Social Architecture model is an agent-based simulation originally created by Classical Econophysics co-author Ian Wright. It works by creating n number of agents who first interact in a labor market to either hire or be hired, creating firms. Agents randomly expend their money, adding it to a general pool of latent demand. Employees are paid a fixed wage and add value to their employer by taking a random amount of from the pool of latent demand. When firms don't have enough money to pay employees they go bankrupt. While the rules of the model are very simply, it has shown itself to be capable of reproducing a wide variety of distributions as they appear in actually existing capitalist economy, including the income distributions of workers and capitalists.

Let's talk about ways to recreate the model, improve upon it, and anything related to it here. My next project is to attempt to add Marx's departments to the model.
