Economic interpretation of fractional derivatives
Valentina V. Tarasova, Vasily E. Tarasov
An economic interpretation of the Caputo derivatives of non-integer orders is proposed. The suggested economic interpretation of the fractional derivatives is based on a generaliza…
Logistic map with memory from economic model
Valentina V. Tarasova, Vasily E. Tarasov
A generalization of the economic model of logistic growth, which takes into account the effects of memory and crises, is suggested. Memory effect means that the economic factors an…
Concept of dynamic memory in economics
Valentina V. Tarasova, Vasily E. Tarasov
In this paper we discuss a concept of dynamic memory and an application of fractional calculus to describe the dynamic memory. The concept of memory is considered from the standpoi…
Dynamic intersectoral models with power-law memory
Valentina V. Tarasova, Vasily E. Tarasov
Intersectoral dynamic models with power-law memory are proposed. The equations of open and closed intersectoral models, in which the memory effects are described by the Caputo deri…
Fractional Dynamics of Natural Growth and Memory Effect in Economics
Valentina V. Tarasova, Vasily E. Tarasov
A generalization of the economic model of natural growth, which takes into account the power-law memory effect, is suggested. The memory effect means the dependence of the process…
