Statistical Economics on Multi-Variable Layered Networks
Tom Erez, Martin Hohnisch, Sorin Solomon
We propose a Statistical-Mechanics inspired framework for modeling economic systems. Each agent composing the economic system is characterized by a few variables of distinct nature…
Socioeconomic Interaction and Swings in Business Confidence Indicators
Martin Hohnisch, Sabine Pittnauer, Sorin Solomon +1
We propose a stochastic model of interactive formation of individual expectations regarding the business climate in an industry. Our model is motivated by a business climate survey…
The Emergence of Spatial Complexity in the immune System
Yoram Louzoun, Sorin Solomon, Henri Atlan +1
Biological systems, unlike physical or chemical systems, are characterized by the very inhomogeneous distribution of their components. The immune system, in particular, is notable…
Discrete Financial Means: When exception rules, mean means nothing; Auto-catalytic Individuals Survive by all Means
Sorin Solomon
The origin of macroscopic complexity is traced in a wide range of systems (imunology, ecology, finance, marketing, etc) to the discrete and auto-catalytic (i.e. multiplicative) cha…
Power Laws and Cities Population
Aharon Blank, Sorin Solomon
We study a few dynamical systems composed of many components whose sizes evolve according to multiplicative stochastic rules. We compare them with respect to the emergence of power…
