We investigated German hog-price dynamics with an innovative ‘diagnostic’ modeling approach. Hog-price cycles are conventionally modeled stochastically—most recently as randomly-shifting sinusoidal oscillations. Alternatively, we applied nonlinear time se... see more

Volatile food prices are held to threaten food security worldwide, but controversy over how to distinguish between ‘normal’ and ‘extreme’ volatility compromises threat assessment and identification of countermeasures. Whether food-market dynamics normally... see more

We devise a decision tool to help economic researchers select a causal detection method compatible with real-world dynamics of an economic system under investigation. We apply it to test for dynamic causality between promotions and sales of a case-study b... see more

In ‘dissipative’ dynamical systems, variables evolve asymptotically toward lowdimensional ‘attractors’ that define their dynamical properties. Unfortunately, real-world dynamical systems are generally too complex for us to directly observe these attractor... see more

The aim of the following paper is to show that it is not possible to penetrate into the depths of Nikolay Raynov's universe and to comprehend its wholeness, without posing and investigating the question about the origin or the foundation of his various cr... see more
