The main task of this work is to develope a model able to encompass, at the same time, Keynesian, demand-driven, and Marxian, profit-driven determinants of fluctuations. Our starting point is the Goodwin's model (1967), rephrased in discrete time and extended by means of a coupled dynamics...

Advances in Physics and Mathematics have proven that our complex world does not obey anymore the standard linear modelling systems rules. This paradigm seems to take over much of the scientific research in all sciences. Psychologists, no matter what their orientation is, are striving to create...

This paper applies non linear methods to analyze and predict the daily open S&P index which is one of the most important stock index in the world .The aim of the analysis is to quantitatively show if the corresponding time series is a deterministic chaotic one and if one or more days ahead...

In preparation for the UN Decade of Education for Sustainable Development, UNESCO communicated its conceptualization of education for sustainable development (ESD). This paper does not assume that UNESCO was ineffective in communicating its approach to ESD; rather, the premise is that UNESCO’s...</i>

The literature on tourism development has focused on a one dimensional relationship between tourism development and quality of life. The impact of shock events on the relationship tourism development and quality of life seems ignored. Rather less attention has been paid to the multi-dimensional...

This article presents an exhaustive analysis of the normal distribution assumption in terms of emerging capital markets. The accuracy of such assumptions is fundamentally contested by the results of empirical analysis. In addition, this paper is also a conceptual debate between classical theory...

Because of sensitive dependence on initial conditions (SDIC), characteristic to chaotic systems, the prediction of such system can be made with an accepted accuracy only for relatively small number of steps ahead. Using artificial techniques like neural networks and support vector machine to...

It is said that theories explain laws, and laws are facts of observation. At the first sight these two concepts reduced to axioms are perfectly logical and consistent, but the law is a valid creation only in an unit of time, starting with the laws of physics and finishing with the ones of...

The article approaches the modelling and simulation of risks in the training of the human resources, as well as the forecast of the degree of human resources training impacted by risks by applying the mathematical tools offered by the Chaos Theory and mathematical statistics. We will highlight...

"The Butterfly Effect In Competitive Markets illustrates through logical market behavior analysis how chaos in the market drives tactics among the market competitors that causes shifts in consumer preferences and guides the buying behavior. Such shifts in consumer behavior are often radical and...

The aim of the article is to show that organization’s potential can be differently described as only by results. The proposals concern using both the category of balance or unbalance and the concept of the chaos edge for describing organization’s potential. The paper takes a closer look at...

In this article we develop a supply chain model of four levels through the utilization of system dynamics with Ithink® and Mathlab® softwares to analyze data. The supply chain is studied from the chaos theory perspective, which helps identifying the sensitive variables that can lead to a state...

The aim of this paper is to develop a continuous time exchange rate model that allows for heterogeneity of the agents' beliefs, in order to explore non-linearities and possible chaotic behaviour. The theoretical model contains an intrinsic non-linearity that gives rise to a jerk differential...

We provide a methodology to study the role of market distortions on the emergence of indeterminacy and bifurcations. Most of the specific market imperfections considered in the related literature are particular cases of our framework. Comparing them we obtain several equivalence results in terms...

Chaotic phenomena, chaos amplification and other interesting nonlinear behaviors have been observed in supply chain systems. Chaos can be defined theoretically if the dynamics under study are produced only by deterministic factors. However, deterministic settings rarely present themselves in...

In this paper, we develop themes from complexity and chaos theory that help to explain the technological change process. We apply two quantifiers, correlation dimensions and Lyapunov exponents, to examine the signs and degrees of chaotic technological dynamics. To illustrate our ideas, we study...

Risk is considered as an important issue in hazardous materials routing problems, in particular once a certain part of the road network has been affected by natural disasters. It could even be a more serious concern when vital hazmat substances, are required to be transported to the affected...
