Consistent Estimation of Agent-Based Models by Simulated Minimum Distance.

Grazzini, Jakob; Richiardi, Matteo G. - Collegio Carlo Alberto, Università degli Studi di Torino - 2013

Agent-based (AB) models are considered a promising tool for macroeconomic analysis. However, until estimation of AB models become a common practice, they will not get to the center stage of macroeconomics. Two difficulties arise in the estimation of AB models: (i) the criterion function has no...

Multi-Equilibria Regulation Agent-Based Model of Opinion Dynamics in Social Networks

Koulouris, Andreas; Katerelos, Ioannis; Tsekeris, Theodore - In: Interdisciplinary Description of Complex Systems - … 11 (2013) 1, pp. 51-70

This article investigates the Multiple Equilibria Regulation (MER) model, i.e., an agent-based simulation model, to represent opinion dynamics in social networks. It relies on a small set of micro-prerequisites (intra-individual balance and confidence bound), leading to emergence of...

Analysis of Asymmetric Two-Sided Matching: Agent-Based Simulation with Theorem-Proof Approach

Shiba, Naoki - In: Journal of Artificial Societies and Social Simulation 16 (2013) 3, pp. 11-11

This paper discusses an extended version of the matching problem which includes the mate search problem; this version is a generalization of a traditional optimization problem. The matching problem is extended to a form of the asymmetric two-sided matching problem. An agent-based simulation...

Walrasian TatÈnnement by Sequential Pairwise Trading: Convergence and Welfare Implications

Miceli, Maria-Augusta; Cecconi, Federico; Cerulli, Giovanni - Dipartimento di Economia e Diritto, Facoltà di Economia - 2013

This paper characterizes the out-of-equilibrium dynamics of a symmetric, pure exchange economy with two goods and N agents with uniformly distributed preferences and identical endowments. Relaxing the auctioneer assumption, but maintaining a global price rule, sequentially random pairwise...

Investment reluctance in supply chains : an agent-based real options approach

Balmann, Alfons; Kataria, Karin; Mußhoff, Oliver - 2013

This paper shows how agent-based stochastic approaches can provide a complementary and more flexible approach to study investment incentives and price dynamics in a real options framework. We particularly study the case of two-stage production chains in which one sector produces an intermediate...

Chapter 9. Heterogeneous Agent Modeling: Experimental Evidence

Arifovic, Jasmina; Duffy, John - In: Handbook of computational economics : Volume 4: …, (pp. 491-540). 2018

We report on experimental evidence rationalizing the use of heterogeneous agent models. We provide compelling evidence that subjects in laboratory experiments often behave in ways that depart from the rational choice ideal. Further, these subjects' heuristic approaches often differ from one...

Chapter 5. Heterogeneous Agent Models in Finance

Dieci, Roberto; He, Xue-Zhong - In: Handbook of computational economics : Volume 4: …, (pp. 257-328). 2018

This chapter surveys the state-of-art of heterogeneous agent models (HAMs) in finance using a jointly theoretical and empirical analysis, combined with numerical analysis from the latest development in computational finance. It provides supporting evidence on the explanatory power of HAMs to...
