Emergence of two-phase behavior in markets through interaction and learning in agents with bounded rationality
نویسندگان
چکیده
Phenomena which involves collective choice of many agents who are interacting with each other and choosing one of several alternatives, based on the limited information available to them, frequently show switching between two distinct phases characterized by a bimodal and an unimodal distribution respectively. Examples include financial markets, movie popularity and electoral behavior. Here we present a model for this biphasic behavior and argue that it arises from interactions in a local neighborhood and adaptation & learning based on information about the effectiveness of past choices.

Development of Reinforcement Learning Algorithm to Study the Capacity Withholding in Electricity Energy Markets
This paper addresses the possibility of capacity withholding by energy producers, who seek to increase the market price and their own profits. The energy market is simulated as an iterative game, where each state game corresponds to an hourly energy auction with uniform pricing mechanism. The producers are modeled as agents that interact with their environment through reinforcement learning (RL...
متن کاملThe Use of Artificially Intelligent Agents with Bounded Rationality in the Study of Economic Markets
The concepts of ‘knowledge’ and ‘rationality’ are of central importance to fields of science that are interested in human behavior and learning, such as artificial intelligence, economics, and psychology. The similarity between artificial intelligence and economics both are concerned with intelligent thought, rational behavior, and the use and acquisition of knowledge has led to the use of econ...
متن کاملBehavioral Economics
Behavioral Economics is the combination of psychology and economics that investigates what happens in markets in which some of the agents display human limitations and complications. We begin with a preliminary question about relevance. Does some combination of market forces, learning and evolution render these human qualities irrelevant? No. Because of limits of arbitrage less than perfect age...
متن کاملEvolving Strategic Behaviors through Competitive Interaction in the Large
The purpose of this paper is to provide a new approach for investigating the competitive interactions in the large. Another purpose of this paper is to study emergent strategic behaviors and to analyze the effects of bounded rationality and the mimicry strategy in the competitive situations. We show how the society gropes for its way towards equilibrium in an imperfect world where agents are se...
متن کاملComparing Bandwidth and Self-control Modeling on Learning a Sequential Timing Task
Modeling is a process which the observer sees another person's behavior and adapts his/her behavior with that which is the result of interaction. The aim of present study was to investigate and compare effectiveness of bandwidth modeling and self-control modeling on performance and learning of a sequential timing task. So two groups of bandwidth and self-control were compared. The task was pres...
