DEPLOYERS: An agent based modeling tool for multi country real world data

TL;DR

DEPLOYERS is an agent-based macroeconomic modeling framework capable of simulating multi-country economic systems with detailed sector and agent interactions, useful for analyzing complex economic data and stylized effects over time.

Contribution

This work extends the DEPLOYERS framework to a multi-country setting, enabling detailed simulation of inter-country economic interactions using real-world data.

Findings

Successfully simulated 46 countries with 64 sectors each.

Parallelized simulation runs on multiple CPU cores for efficiency.

Generated detailed economic activity data suitable for input-output analysis.

Abstract

We present recent progress in the design and development of DEPLOYERS, an agent-based macroeconomics modeling (ABM) framework, capable to deploy and simulate a full economic system (individual workers, goods and services firms, government, central and private banks, financial market, external sectors) whose structure and activity analysis reproduce the desired calibration data, that can be, for example a Social Accounting Matrix (SAM) or a Supply-Use Table (SUT) or an Input-Output Table (IOT).Here we extend our previous work to a multi-country version and show an example using data from a 46-countries 64-sectors FIGARO Inter-Country IOT. The simulation of each country runs on a separate thread or CPU core to simulate the activity of one step (month, week, or day) and then interacts (updates imports, exports, transfer) with that country's foreign partners, and proceeds to the next step. This interaction can be chosen to be aggregated (a single row and column IO account) or disaggregated (64 rows and columns) with each partner. A typical run simulates thousands of individuals and firms engaged in their monthly activity and then records the results, much like a survey of the country's economic system. This data can then be subjected to, for example, an Input-Output analysis to find out the sources of observed stylized effects as a function of time in the detailed and realistic modeling environment that can be easily implemented in an ABM framework.
