Agent-based modelling

An agent-based model (ABM) is a computational model for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) in order to understand the behavior of a system and what governs its outcomes. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo methods are used to understand the stochasticity of these models. [Wikipedia]

ABMs at Sant'Anna

Some of the most important ABMs developed at Sant'Anna in the past years are available here.

K+S Models

Basic K+S

The Keynes + Schumpeter computer-simulation model (K+S) was designed to allow the study of several relevant properties of the macroeconomic system. K+S is a general disequilibrium, stock-and-flow consistent agent-based theoretical model, populated by heterogeneous firms, who behave according to bounded-rational rules.

The model was first introduced in:

    Dosi, G., G. Fagiolo, and A. Roventini (2010). Schumpeter meeting Keynes: A policy-friendly model of endogenous growth and business cycles. Journal of Economic Dynamics and Control, 34(9):1748-1767, DOI.

Finance-augmented K+S

The finance-augmented Keynes + Schumpeter computer-simulation model (K+S) was designed to allow the study of several relevant properties of the macroeconomic system, with an emphasis on the financial side of the economy. K+S is a general disequilibrium, stock-and-flow consistent agent-based theoretical model, populated by heterogeneous firms and banks, which behave according to bounded-rational rules.

The model was first introduced in:

    Dosi, G., G. Fagiolo, A. Roventini, and T Treibich (2015). Fiscal and monetary policies in complex evolving economies. Journal of Economic Dynamics and Control, 52(C):166-189, DOI.

Energy-augmented K+S

The energy-augmented Keynes + Schumpeter computer-simulation model (K+S) was designed to allow the study of several relevant properties of the macroeconomic and energy systems, and their impacts on climate change. K+S is a general disequilibrium, stock-and-flow consistent agent-based theoretical model, populated by heterogeneous firms, banks, and energy producers, which behave according to bounded-rational rules.

The model was first introduced in:

Labor-augmented K+S

The Labor-augmented Keynes + Schumpeter computer-simulation model (K+S) was designed to allow the study of several relevant properties of the macroeconomic system. K+S is a general disequilibrium, stock-and-flow consistent agent-based theoretical model, populated by heterogeneous firms and workers, who behave according to bounded-rational rules.

The model was first introduced in:

    Dosi, G., M. C. Pereira, A. Roventini, and M. E. Virgillito (2017). When more Flexibility Yields more Fragility: the Microfoundations of Keynesian Aggregate Unemployment. Journal of Economic Dynamics and Control, 81:162-186, DOI.

Multi-industry K+S

The Multi-industry Keynes + Schumpeter computer-simulation model (K+S) was designed to allow the study of several relevant properties of the macroeconomic system. K+S is a general disequilibrium, stock-and-flow consistent agent-based theoretical model, populated by heterogeneous industries, firms, and workers, which behave according to bounded-rational rules.

The model was first introduced in:

    Dosi, G., M. C. Pereira, A. Roventini, and M. E. Virgillito (2021). Technological paradigms, labour creation and destruction in a multi-sector agent-based model. LEM Working Papers, 2021-17, WP.

DSK Model

DSK Refresh

The Dystopian Schumpeter Meeting Keynes computer-simulation model (DSK) was designed to allow the study of several relevant properties of the macroeconomic system, and its impacts on climate change. DSK Refresh is a general disequilibrium, stock-and-flow consistent agent-based theoretical model, populated by heterogeneous firms and banks, which behave according to bounded-rational rules.

The model was first introduced in:

    Lamperti, F., G. Dosi, G. Fagiolo, M. Napoletano, A. Roventini, and A. Sapio (2018). Faraway, So Close: Coupled Climate and Economic Dynamics in an Agent-based Integrated Assessment Model. Ecological Economics, 150(C):315-339, DOI.

Industry Model

Base model

This is a very parsimonious evolutionary model whereby the dynamics is driven by learning by incumbent and entrant firms (or at least by entrants alone) together with competitive selection.

The model was first introduced in:

    Dosi, G., Pereira, M. C., Virgillito, M. E. (2017). The footprint of evolutionary processes of learning and selection upon the statistical properties of industrial dynamics. Industrial and Corporate Change, 26(2):187-210, DOI.

Island Model

Base model

This is a model of endogenous growth in which firms are modeled as boundedly-rational, locally interacting, agents.

The model was first introduced in:

    Fagiolo, G., Dosi, G., (2003). Exploitation, exploration and innovation in a model of endogenous growth with locally interacting agents. Structural Change and Economic Dynamics, 14:237-273, DOI.
