Calibrating Agent-based Models to Microdata with Graph Neural Networks

no code implementations15 Jun 2022 Joel Dyer, Patrick Cannon, J. Doyne Farmer, Sebastian M. Schmon

Calibrating agent-based models (ABMs) to data is among the most fundamental requirements to ensure the model fulfils its desired purpose.

Black-box Bayesian inference for economic agent-based models

no code implementations1 Feb 2022 Joel Dyer, Patrick Cannon, J. Doyne Farmer, Sebastian Schmon

We present benchmarking experiments in which we demonstrate that neural network based black-box methods provide state of the art parameter inference for economic simulation models, and crucially are compatible with generic multivariate time-series data.

In and out of lockdown: Propagation of supply and demand shocks in a dynamic input-output model

no code implementations18 Feb 2021 Anton Pichler, Marco Pangallo, R. Maria del Rio-Chanona, François Lafond, J. Doyne Farmer

Looking back at predictions that we released in May, we show that the model predicted aggregate dynamics very well, and sectoral dynamics to a large extent.

Simultaneous supply and demand constraints in input-output networks: The case of Covid-19 in Germany, Italy, and Spain

no code implementations19 Jan 2021 Anton Pichler, J. Doyne Farmer

Natural and anthropogenic disasters frequently affect both the supply and demand side of an economy.

How Market Ecology Explains Market Malfunction

no code implementations20 Sep 2020 Maarten P. Scholl, Anisoara Calinescu, J. Doyne Farmer

Here we develop an alternative based on concepts and methods developed by biologists, in which the wealth invested in a financial strategy is like the abundance of a species.

Measuring productivity dispersion: a parametric approach using the Lévy alpha-stable distribution

no code implementations11 Oct 2019 Jangho Yang, Torsten Heinrich, Julian Winkler, François Lafond, Pantelis Koutroumpis, J. Doyne Farmer

It is well-known that value added per worker is extremely heterogeneous among firms, but relatively little has been done to characterize this heterogeneity more precisely.

Automation and occupational mobility: A data-driven network model

1 code implementation10 Jun 2019 R. Maria del Rio-Chanona, Penny Mealy, Mariano Beguerisse-Díaz, Francois Lafond, J. Doyne Farmer

The potential impact of automation on the labor market is a topic that has generated significant interest and concern amongst scholars, policymakers, and the broader public.

How production networks amplify economic growth

no code implementations17 Oct 2018 James McNerney, Charles Savoie, Francesco Caravelli, Vasco M. Carvalho, J. Doyne Farmer

Technological improvement is the most important cause of long-term economic growth.

How markets slowly digest changes in supply and demand

no code implementations4 Sep 2008 Jean-Philippe Bouchaud, J. Doyne Farmer, Fabrizio Lillo

In this article we revisit the classic problem of tatonnement in price formation from a microstructure point of view, reviewing a recent body of theoretical and empirical work explaining how fluctuations in supply and demand are slowly incorporated into prices.
