In this work, we investigate the Model of Employment, Production and Consumption, as introduced in a series of papers by I. Wright [1-3] from the perspective of statistical physics, and we focus on the presence of equilibrium.
The model itself belongs to the class of multi-agent computational models, which aim to explain macro-economic behavior using explicit micro-economic interactions. Based on the mean-field approximation, we form the Fokker-Plank equation(s) and then formulate conditions forming the stationary solution, which results in a system of non-linear integral-differential equations.
This approximation then allows the presence of non-equilibrium stationary states, where the model is a mixed additive-multiplicative model.
