This paper advances understanding of multiplier-accelerator interaction in European
countries in the 21st century. More than eight decades from the contributions of Keynes and …

This review analyzes articles on the mathematical modeling of economic facts and
processes. Mathematical modeling of the economy has rapidly developed in the past and …

This paper examines modern economic growth according to the multidimensional scaling
(MDS) method and state space portrait (SSP) analysis. Electing GDP per capita as the main …

In this article, we use a generalized system of differential equations of fractional‐order to
incorporate memory into an electricity market model. By using this idea, essential …

In this article, we consider a class of systems of differential equations with multiple delays.
We define a transform that reformulates the system with delays into a singular linear system …

In this article, we study a class of non-linear neutral delay differential equations of third
order. We first prove criteria for non-existence of non-Kneser solutions, and criteria for non …

In this work, new conditions were obtained for the oscillation of solutions of fourth-order non-
linear neutral differential equations (NDEs) using the Riccati technique. These oscillation …

This paper studies the equilibrium of an extended case of the classical Samuelson's
multiplier–accelerator model for national economy. This case has incorporated some kind of …

The main objective of this article is to develop Bayesian optimal control for a class of non-
autonomous linear stochastic discrete time systems. By taking into consideration that the …

In this article, we assume a union of countries where each national economy interacts with
the others. We propose a new model where (a) delayed variables are incorporated into the …
