Commodities, Financialization, and Heterogeneous Agents [PDF]
SSRN Electronic Journal, 2016 The term 'financialization' describes the phenomenon that commodity contracts are traded for purely financial reasons and not for motives rooted in the real economy. Recently, financialization has been made responsible for causing adverse welfare effects especially for low-income and low-wealth agents, who have to spend a large share of their income ...

Frontiers in Neuroscience, 2023 Humans do not learn everything from the scratch but can connect and associate the upcoming information with the exchanged experience and known knowledge. Such an idea can be extended to cooperated multi-reinforcement learning and has achieved its success

Wealth distribution across communities of adaptive financial agents
New Journal of Physics, 2015 This paper studies the trading volumes and wealth distribution of a novel agent-based model of an artificial financial market. In this model, heterogeneous agents, behaving according to the Von Neumann and Morgenstern utility theory, may mutually ...

Complexity, 2003 AbstractIn this article, we present a multiagent system (MAS) simulation of a financial market and investigate the requirements to obtain realistic data. The model consists of autonomous, interactive agents that buy stock on a financial market. Transaction decisions are based on a number of individual and collective elements, the former being risk ...

Multi-level opinion dynamics under bounded confidence. [PDF]
PLoS ONE, 2012 Opinion dynamics focuses on the opinion evolution in a social community. Recently, some models of continuous opinion dynamics under bounded confidence were proposed by Deffuant and Krause, et al. In the literature, agents were generally assumed to have a

Evaluation Mechanism of Collective Intelligence for Heterogeneous Agents Group
IEEE Access, 2020 Collective intelligence is manifested when multiple agents coherently work in observation, interaction, decision-making and action. In this paper, we define and quantify the intelligence level of heterogeneous agents group organized in a flat structure ...

Monetary policy and inequality under household heterogeneity and incomplete markets
Economía, 2022 Motivated by the empirical evidence of the effects of unanticipated nominal interest rate increases on the evolution of household inequality in Mexico, which highlight the importance of insurance mechanisms to deal with idiosyncratic risks, the paper ...

Programming Verifiable Heterogeneous Agent Systems [PDF]
, 2009 Our overall aim is to provide a verification framework for practical multi-agent systems. To achieve practicality, we must be able to describe and implement heterogeneous multi-agent systems. To achieve verifiability, we must define semantics appropriately for use in formal verification.

Wealth Share Analysis with “Fundamentalist/Chartist” Heterogeneous Agents
Abstract and Applied Analysis, 2014 We build a multiassets heterogeneous agents model with fundamentalists and chartists, who make investment decisions by maximizing the constant relative risk aversion utility function. We verify that the model can reproduce the main stylized facts in real
