Stock-Flow Consistent Agent-Based Models

I wasn’t too excited about “agent-based models” before this, but I saw this paper What Drives Markups? Evolutionary Pricing In An Agent-Based Stock-Flow Consistent Macroeconomic Model by Marc Lavoie (co-authored with Pascal Seppecher and Isabelle Salle) and it got me a bit interested.

From the paper:

ABMs are conceived to analyze out-of-equilibrium dynamics and adaptation processes
from heterogeneous and interacting entities … On a more specific note, we use a stock-flow consistent (hereafter, SFC) framework … there has been a multiplicity of macroeconomic models that combine two important features: the principle of decentralization/disaggregation which is found in ABM and the principle of stock-flow consistency … In an ABM, macroeconomic variables are the result of a simple process of aggregation of individual data, as in the real word [sic] …, so that the accounting accuracy provided by the SFC ensures the relevance of the aggregation process …, as well as the interconnected nature of the balance sheets of all agents. Symmetrically, AB principles could provide micro-foundations to SFC macroeconomics, that is, a way to logically articulate and rigorously organize the interactions between the micro and the macro levels.
