Bayesian Exploration with Heterogeneous Agents [PDF]
The World Wide Web Conference, 2019 It is common in recommendation systems that users both consume and produce information as they make strategic choices under uncertainty. While a social planner would balance "exploration" and "exploitation" using a multi-armed bandit algorithm, users' incentives may tilt this balance in favor of exploitation.

Relative Extinction of Heterogeneous Agents [PDF]
, 2009 In all the existing literature on survival in heterogeneous economies, the rate at which an agent vanishes in the long run relative to another agent can be characterized by the difference of the so-called survival indices, where each survival index ...

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 ...

Heterogeneous-Agent Reinforcement Learning
CoRR, 2023 The necessity for cooperation among intelligent machines has popularised cooperative multi-agent reinforcement learning (MARL) in AI research. However, many research endeavours heavily rely on parameter sharing among agents, which confines them to only homogeneous-agent setting and leads to training instability and lack of convergence guarantees.

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 ...

Journal of Economic and Financial Sciences, 2009 Unemployment in South Africa has reached crisis proportions and does not seem to be decreasing in concurrence with the more propitious economic reality. Indeed, the unemployment process seems to be isolated from economic reality and has developed a life ...
