چکیده

We study the effect of size-based regulation on an economic system. A multiple-trait model of self-organized criticality is used to simulate the economic system. The major difference of this work from previous studies is that firm’s fitness is not characterized by a single number but by M traits. Each trait represents one aspect of the competitiveness of the firm, and firm’s size is one of these traits. Major finding drawn from the present study is that the effectiveness of regulations decreases with increasing M, i.e., size-based regulations are less effective when the overall fitness of a firm is determined by more factors. r 2006 Elsevier B.V.

Cellular Automata and Self Organized Criticality

Cellular automata provide a fascinating class of dynamical systems capable of diverse complex behavior. These include simpliied models for many phenomenaseen in nature. Among other things, they provide insight into self-organized critical-ity, wherein dissipative systems naturally drive themselves to a critical state with important phenomena occurring over a wide range of length and time scales...

Avalanche Dynamics in Piles of Two Types of Sand

Some real systems usually drive themselves into a critical state. These systems are said to be in a state of selforganized criticality [1]. The theory of self-organized criticality aims to describe interactive, dissipative and self sustaining systems with many degrees of freedom. Hence it complements the chaos concept. These systems are characterized by power law statistics. Self-organized crit...

A Self-organized Multi Agent Decision Making System Based on Fuzzy Probabilities: The Case of Aphasia Diagnosis

Aphasia diagnosis is a challenging medical diagnostic task due to the linguistic uncertainty and vagueness, large number of measurements with imprecision, inconsistencies in the definition of Aphasic syndromes, natural diversity and subjectivity in test objects as well as in options of experts who diagnose the disease. In this paper we present a new self-organized multi agent system that diagno...

Urban self-organization in practice: identifying a model for understanding collective action in neighborhoods of Sabzevar City

Introduction: Studies show that the concept of urban self-organization can pave the way for researchers to achieve actual citizen participation. Despite the importance of this issue, there is a significant cognitive gap in this field in Iran. Due to the contextual nature of urban self-organization, to use this concept in the development of the country's neighborhoods, one must first understand ...

Dynamical Explanation for the Emergence of Power Lawin a Stock Market

Power laws are found in a wide range of diierent systems: from sand piles to word occurrence frequencies and to the size distribution of cities. The natural emergence of these power laws in so many diierent systems, which has been called self organized criticality, seems rather mysterious and awaits a rigorous explanation. In this letter we study the stationary regime of a previously introduced...
