The system allows the simulation of an economic system which is described with a model. The economic model evolves over time according to its status and to the inputs received from the external world. The experimenter is able to change the parameters of the economic model and is unique in the system. The economic subjects are asked by the economic model to give inputs on the basis of the actual model status. The economic model is characterized by a state, exogenous and endogenous variables that evolve over time.
Evolution depends on the state and on the inputs of the system.
The state of the system evolves according to the model equations while the inputs are given by the economic subjects. The experimenter has the role to supervise the model evolution and to change some of the exogenous variables. In the market, each subject may buy and sell chips in a sequence of periods. The subjects uses one type of currency in the market. Each subject play in the market for two consecutive periods at a time.
