Elements of the parametrical regulation theory of the national economy evolution based on computable general equilibrium models

摘要

The paper presents some results on the development of the parametrical regulation theory based on computable general equilibrium (CGE) models, that are discrete dynamic systems (semi-cascades), and shows the efficiency of application of this theory. We propose methods of parametrical identification, assessment of weak structural stability of the discrete dynamic system and the method of parametrical regulation of the dynamical system evolution in the form of formulating and solving the problem of variational calculus. We present some theorems about the existence and continuous dependence of the criterion's optimal value on the parameter of the stated variational calculus problem. The effectiveness of the theory of parametrical regulation is illustrated with the help of a CGE model.
