A diversity of integrated assessment models (IAMs) coexists due to the different approaches
developed to deal with the complex interactions, high uncertainties and knowledge gaps …

Purpose The term “agent-based modelling”(ABM) is a buzzword which is widely used in the
scientific literature even though it refers to a variety of methodologies implemented in …

This paper presents the results of investigating the dynamics of an economic system with
chaotic behavior and a suboptimal control proposal to suppress the chaotic behavior …

We discuss a method for obtaining exact solutions of nonlinear partial differential equations
called the Simple Equations Method (SEsM) which is based on representation of the …

A fractional-order finance system with negative values for system's parameters is introduced.
Based on an integer-order finance system with two nonlinearities, we discovered chaos in …

The inherent instability of the financial system itself may lead to chaos and unpredictable
economic disorder. It is meaningful to study the stability and control theory of financial …

Modeling complex systems with large numbers of degrees of freedom has become a grand
challenge over the past decades. In many situations, only a few variables are actually …

Abstract While Data Science has become increasingly significant for business strategies,
operations, performance, efficiency and prediction, there is little work on this to provide a …

A novel fractional order dynamical system with a variable double-scroll attractor on a line,
lattice and 3D grid is introduced. This system belongs to a class of chaotic systems with …

We reinvestigate the classic portfolio optimization problem where the notion of portfolio risk
is captured by the “Foster–Hart risk”—a new, bankruptcy-proof, reserve based measure of …
