Multicomponent dynamics of competitive single-sector economy development

Models of multicomponent dynamics of competitive single-sector economy development are formalized and studied. The first model is completely deterministic and describes economy under conditions of perfect competition. It is supposed that companies plan their product output due to Cournot game strategy. In two other models external parameters are stochastic. Different approaches to formalization of stochastic models and numerical schemes to solve their equations are proposed. Examples are given.
