Coalition Stability with Heterogeneous Agents [PDF]
Economics Bulletin, 2011 We analyze coalition formation with heterogeneous agents based on an individual stability concept. Defining exchanging and refractory agents, we give existence and enlargement conditions for coalitions with heterogeneous agents.

Searching by Heterogeneous Agents [PDF]
Journal of Computer and System Sciences, 2019 In this work we introduce and study a pursuit-evasion game in which the search is performed by heterogeneous entities. We incorporate heterogeneity into the classical edge search problem by considering edge-labeled graphs: once a search strategy initially assigns labels to the searchers, each searcher can be only present on an edge of its own label. We

Contests With Heterogeneous Agents [PDF]
SSRN Electronic Journal, 2006 We study tournaments with many ex-ante asymmetric contestants, whose valuations for the prize are independently distributed. First, we characterize the equilibria in monotone strategies, second, we provide sufficient conditions for the equilibrium uniqueness and, finally, we reconcile the experimental evidence documenting the 'workaholic' behavior in ...

Fiscal multipliers: A heterogenous‐agent perspective [PDF]
Quantitative Economics, 2021 We use an analytically tractable heterogeneous‐agent (HANK) version of the standard New Keynesian model to show how the size of fiscal multipliers depends on (i) the distribution of factor incomes, and (ii) the source of nominal rigidities. With sticky prices but flexible wages, the standard representative‐agent (RANK) model predicts large multipliers ...

Smart Agents and Sentiment in the Heterogeneous Agent Model [PDF]
Prague Economic Papers, 2009 In this paper we extend the original heterogeneous agent model by introducing smart traders and changes in agents’ sentiment. The idea of smart traders is based on the endeavor of market agents to estimate future price movements. By adding smart traders and changes in sentiment we try to improve the original heterogeneous agents model so that it ...

Distributed Bandits with Heterogeneous Agents
IEEE INFOCOM 2022 - IEEE Conference on Computer Communications, 2022 This paper tackles a multi-agent bandit setting where $M$ agents cooperate together to solve the same instance of a $K$-armed stochastic bandit problem. The agents are \textit{heterogeneous}: each agent has limited access to a local subset of arms and the agents are asynchronous with different gaps between decision-making rounds.

Heterogeneous Retirement Savings Strategy Selection with Reinforcement Learning
Entropy, 2023 Saving and investment behaviour is crucial for all individuals to guarantee their welfare during work-life and retirement. We introduce a deep reinforcement learning model in which agents learn optimal portfolio allocation and saving strategies suitable ...

Monetary Policy with Heterogeneous Agents [PDF]
SSRN Electronic Journal, 2012 We build a New Keynesian model in which heterogeneous workers differ with regard to their employment status due to search and matching frictions in the labor market, their potential labor income, and their amount of savings. We use this laboratory to quantitatively assess who stands to win or lose from unanticipated monetary accommodation and who ...

Heterogeneous Agents Situated in Heterogeneous Spaces
Applied Artificial Intelligence, 2002 This paper introduces the Multi-layered Multi-Agent Situated System model (MMASS), a model for Multi-Agent Systems (MAS) situated in an environment. The main feature of the MMASS model is to give an explicit definition of the spatial structure of the environment in which the system of situated agents are acting and interacting.
