We explore the macro-financial consequences of the disruption of a supply chain in an agent based framework characterized by two networks, a credit network connecting banks and firms and a production network connecting upstream and down-stream firms. We consider two scenarios. In the first one,...

This paper brings novel insights into group coordination and price dynamics in complex environments. We implement an overlapping-generation model in the lab, where the output dynamics is given by the well-known chaotic quadratic map. This model structure allows us to study previously unexplored...

This chapter surveys work dedicated to macroeconomic analysis using an agent-based modeling approach. After a short review of the origins and general characteristics of this approach a systemic comparison of the structure and modeling assumptions of a set of important (families of) agent-based...

I propose a novel method to test rational expectations. This method views the conditional expectation operator as a self-adjoint linear projection, which can exclude expectations formation models with only information frictions, overconfidence, or diagnostic expectations using aggregate level...

I introduce a survey of economic expectations formed by querying a large language model (LLM)’s expectations of various financial and macroeconomic variables based on a sample of news articles from the Wall Street Journal between 1984 and 2021. I find the resulting expectations closely match...

In this paper we develop a Hybrid Macroeconomic ABM. The economy is populated with firms heterogeneous in term of financial fragility, measured via the Equity Ratio. Firms are maximizing profit by choosing capital, which can not be raised on the stock market. Therefore they have to rely on a...

In a NK model with two types of rational agents, savers and capitalists, and non-maximizing banks, financial shocks do affect the macroeconomic dynamics depending on banks' behaviour as for their leverage ratio. We first show that the level of banks' leverage - which may be imposed by banks...
