Chaotic maps are known for its random property and its use in cryptography in particular image encryption is unavoidable. In this paper, Duffing map is used for permutation and two chaotic maps such as Henon map and logistic map are employed for diffusion, Henon map gets its initial values from...

The purpose of this paper is to construct a structural macroeconomic model to design monetary and fiscal policies aimed at attaining macroeconomic objectives. The study further attempts to simulate a baseline and policy scenario to evaluate the impact of such monetary and fiscal policy...

We present a global sensitivity analysis that quantifies the impact of parameter uncertainty on model outcomes. Specifically, we propose variance‐decomposition‐based Sobol' indices to establish an importance ranking of parameters and univariate effects to determine the direction of their...

The focus of this paper is an information theoretic-symbolic logic approach to extract information from complex economic systems and unlock its dynamic content. Permutation Entropy (PE) is used to capture the permutation patterns-ordinal relations among the individual values of a given time...

We present a dynamic model of competition in the media industry in which behavioral media outlets compete for the publication of scoops, and both the publication of scoops and their veracity determine an outlet’s future audience. We study the dynamics of the audiences of outlets and how those...
